Abstract:

In the manufacture of wires designed for the welding of low-alloy fine-grain steels, multiple internal discontinuities appear during some periods that are the cause of major failures (cracking) of the wires. To establish the causes of this phenomenon, a complex analysis was performed making use of light and electron microscopy, metallography, microfractography, computerized tomography and hardness measurement. The analysis revealed that wire cracking in course of wire drawing was due to the superposition of the effects of an inappropriate structure of the initial intermediate product (the presence of polyhedral grains of hard bainitic phase) and unsuitable conditions of the forming process.

Abstract:

The migration of Kirschner wires (K-wires) is a rare but significant complication of osteosynthesis interventions, and numerous cases of wire migrations have been reported in the literature. Nevertheless, migration into the spinal canal is very rare, with only 10 cases reported thus far. The authors present a case of K-wire migration into the spinal canal, together with a review of the relevant literature. A 30-year-old male who had suffered a right clavicle fracture in a motorcycle accident was treated with 2 K-wires. Four months after the initial fixation, while he was lifting his child, he experienced short-term pain in his back, numbness in all 4 extremities, followed by a spontaneous decrease in numbness affecting only the ulnar nerve dermatomes bilaterally, and a persistent headache. No urinary incontinence was present. Simple radiography studies of the cervical spine revealed a wire in the spinal canal, penetrating the T-2 foramen and reaching the contralateral foramen of the same vertebra. Computerized tomography showed the wire positioned in front of the spinal cord. Surgery for wire extraction was performed with the patient under general anesthesia, and he experienced relief of the symptoms immediately after surgery. This case is unique because the wire caused no damage to the spinal cord but did cause compression-related symptomatology and headache, which have not been reported in osteosynthesis wire migration to the thoracic region.

Abstract:

The wire-mesh capacitance tomography (WMCT) has been applied to visualize 2D of the distribution of electric field intensity in the treatment planning system (TPS) of electro-capacitive cancer therapy (ECCT) using human head model. WMCT is proposed in this study to estimate accurately the distribution of electric field intensity which is the main optimum factors of ECCT in order to compensate the inaccuracy of TPS ECCT simulation. The experimental and simulation studies were conducted with wire-mesh sensor consisted of 8×8 wire matrix of copper in human head model using two type of helmet ECCT. The result of electric field value at the intersection wire-mesh have been compared between experimental studies and simulation studies. The electric field average value resulted from ECCT helmet-1 is higher than ECCT helmet-2. The average electric field generated by the ECCT helmet-1 is 1585.72 V/m in an air medium, 97.43 V/m in grey matter and 80.58 V/m in the cancer. While the average electric field generated by the ECCT helmet-2 is 1413.28 V/m in an air medium, 64.20 V/m in grey matter and 52.65 V/m in the cancer. ECCT helmet-1 and helmet-2 result the different of electric field distribution pattern. ECCT helmet-1 is more optimal for used to patient has cancer position in the right and bottom, while ECCT helmet-2 is more optimal for used to patient has cancer position in the top and bottom.

Abstract:

Foreign body ingestion is a common reason for visiting the emergency room. Foreign bodies can lodge anywhere in the upper aerodigestive tract and can sometimes be difficult to extract. Wire bristles that dislodge from grill-cleaning wire brushes and which are then accidentally swallowed can be particularly challenging to remove due to their small size, propensity to become embedded, and their ability to migrate through tissues. This case reveals the speed with which wire bristle foreign bodies can migrate through tissues and exemplifies the need to obtain computerized tomography evaluations in close proximity to any planned attempt to remove them.

Full text

Abstract:

Automatic lumen segmentation from intravascular optical coherence tomography (IVOCT) images is an important and fundamental work for diagnosis and treatment of coronary artery disease. However, it is a very challenging task due to irregular lumen caused by unstable plaque and bifurcation vessel, guide wire shadow, and blood artifacts. To address these problems, this paper presents a novel automatic level set based segmentation algorithm which is very competent for irregular lumen challenge. Before applying the level set model, a narrow image smooth filter is proposed to reduce the effect of artifacts and prevent the leakage of level set meanwhile. Moreover, a divide-and-conquer strategy is proposed to deal with the guide wire shadow. With our proposed method, the influence of irregular lumen, guide wire shadow, and blood artifacts can be appreciably reduced. Finally, the experimental results showed that the proposed method is robust and accurate by evaluating 880 images from 5 different patients and the average DSC value was 98.1%±1.1%.

Abstract:

Background: Frontal sinus fractures are relatively rare. Their surgical management significantly differs depending on whether the posterior wall is invaded and the clinical features vary. A bicoronal incision or endoscopic approach can be used. However, the minimally invasive approach has been attracting attention, leading us to introduce a simple and effective surgical method using multiple-threaded Kirschner wires.Methods: All patients had isolated anterior wall fractures without nasofrontal duct impairment. The depth from the skin to the posterior wall was measured using computed tomography to prevent injury. The edge of the bone segment on the skin was marked, a threaded Kirschner wire was inserted into the center of the bone segment, and multiple Kirschner wires were gently reduced simultaneously.Results: Surgery was performed on 11 patients. Among them, seven patients required additional support for appropriate fracture reduction. Therefore, a periosteal elevator was used as an adjunct through a small sub-brow incision because the reduction was incomplete with the Kirschner wire alone. The reduction results were confirmed using facial bone computed tomography 1 to 3 days postoperatively. The follow-up period was 3 to 12 months.Conclusion: The patients had no complications and were satisfied with the surgical results. Here we demonstrated an easy and successful procedure to reduce a pure anterior wall frontal sinus fracture via non-invasive threaded Kirschner wire reduction.

Abstract:

Background: The aim is to compare the machine learning-based coronary-computed tomography fractional flow reserve (CT-FFRML) and coronary-computed tomographic morphological plaque characteristics with the resting full-cycle ratio (RFRTM) as a novel invasive resting pressure-wire index for detecting hemodynamically significant coronary artery stenosis. Methods: In our single center study, patients with coronary artery disease (CAD) who had a clinically indicated coronary computed tomography angiography (cCTA) and subsequent invasive coronary angiography (ICA) with pressure wire-measurement were included. On-site prototype CT-FFRML software and on-site CT-plaque software were used to calculate the hemodynamic relevance of coronary stenosis. Results: We enrolled 33 patients (70% male, mean age 68 ± 12 years). On a per-lesion basis, the area under the receiver operating characteristic curve (AUC) of CT-FFRML (0.90) was higher than the AUCs of the morphological plaque characteristics length/minimal luminal diameter4 (LL/MLD4; 0.80), minimal luminal diameter (MLD; 0.77), remodeling index (RI; 0.76), degree of luminal diameter stenosis (0.75), and minimal luminal area (MLA; 0.75). Conclusion: CT-FFRML and morphological plaque characteristics show a significant correlation to detected hemodynamically significant coronary stenosis. Whole CT-FFRML had the best discriminatory power, using RFRTM as the reference standard.

AbstractBackgroundThis paper reports the dangers of an ingested metal wire bristle from a barbeque brush, which resulted in oesophageal perforation.Case reportA 49-year-old gentleman presented to the emergency department with foreign body sensation and odynophagia after having consumed barbequed lamb for lunch. Computed tomography of the neck demonstrated a thin linear opacity near the thoracic inlet. The object could not be visualised on emergent rigid oesophagoscopy. Subsequent neck exploration enabled localisation of a retropharyngeal abscess and a thin wire bristle from a barbeque brush.ConclusionAlways consider the utensils employed in food preparation as a differential in ingested foreign bodies. Thin wire objects have a high propensity to migrate and result in complications, hence urgent intervention is vital.

Abstract:

Abstract Objective: To evaluate the accuracy of a novel bone-mounted miniature robotic system for percutaneous placement of pedicle and translaminar facet screws. Methods: Thirty-five spinal levels in 10 cadavers were instrumented. Each cadaver's entire torso was scanned before the procedure. Surgeons planned optimal entry points and trajectories for screws on reconstructed three-dimensional virtual x-rays of each vertebra. Either a clamp or a minimally invasive external frame was attached to the bony anatomy. Anteroposterior and lateral fluoroscopic images using targeting devices were obtained and automatically registered with the virtual x-rays of each vertebra generated from the computed tomographic scan obtained before the procedure. A miniature robot was mounted onto the clamp and external frame and the system controlled the robot's motions to align the cannulated drill guide along the planned trajectory. A drill bit was introduced through the cannulated guide and a hole was drilled through the cortex. Then, K-wires were introduced and advanced through the same cannulated guide and left inside the cadaver. The cadavers were scanned with computed tomography after the procedure and the system's accuracy was evaluated in three planes, comparing K-wire positions with the preoperative plan. A total of fifty-five procedures were evaluated. Results: Twenty-nine of 32 K-wires and all four screws were placed with less than 1.5 mm of deviation; average deviation was 0.87 ± 0.63 mm (range, 0-1.7 mm) from the preoperative plan in this group. Sixteen of 19 K-wires were placed with less than 1.5 mm of deviation. There was one broken and one bent K-wire. Another K-wire was misplaced because of collision with the previously placed wire on the contralateral side of the same vertebra because of a mistake in planning, resulting in a 6.5-mm deviation. When this case was excluded, average deviation was 0.82 ± 0.65 mm (range, 0-1.5 mm). Conclusion: These results verify the system's accuracy and support its use for minimally invasive spine surgery in selected patients.

Abstract:

Kirschner wire is frequently used in orthopedic surgery, and migration is not exceptional. Intrathoracic migration is well-known, especially after surgery on the shoulder girdle, however, intratracheal migration is extremely rare. We describe a case of intratracheal migration of two Kirschner wires in a 41-year-old man who had them placed two years previously for a right clavicle fracture. He experienced chest pain followed by hemoptysis. Thoracic computed tomography revealed intratracheal migration. Remove of the Kirschner wires was performed by a cervical-sternotomy approach. Prompt removal of migrated Kirschner wires must be carried out urgently to avoid fatal complications.

The aim of this study of 21 cadaveric wrists was to assess the usefulness of such a wire in Herbert’s B2-type fractures. A B2-type fracture was created experimentally on each scaphoid. An antirotation wire was inserted in eight wrists. Retrograde percutaneous fixation using a double-threaded headless cannulated screw was performed on all wrists. Computed tomography was used to measure interfragmentary rotation. No interfragmentary rotation was noted in either group. Our study suggests that using an antirotation wire may be unnecessary when performing retrograde percutaneous screw fixation of isolated B2-type scaphoid fractures.

Abstract:

Swallowing of foreign bodies (FB), and sensation of such in the throat, is a common complaint in the emergency department setting, with roughly 80,000 visits in 2010 for FB ingestion.1 Grill wire brushes are a rarely reported, accidental FB ingestion, although recent literature suggests that it is more common than initially thought.2 This is a report of a female with acute onset odynophagia after a meal, with a normal laryngoscopic exam that used flexible fiberoptics. Evidence of a metallic linear density was present in the retropharynx on computed tomography imaging, most consistent with a wire from a grill wire brush.

Abstract:

The characteristics of flow configuration in pipes are very important in the oil industry due to its role in governing equipment design. In vertical risers, many flow configurations could be observed such as bubbly, slug, churn, and annular flow. In this project, two tomographic techniques have been applied simultaneously to the flow in a vertical riser: the Electrical Capacitance Tomography (ECT) technique and the Capacitance Wire Mesh Sensor (WMS) technique. The employed pipe diameter was 50mm and the superficial studied velocities were 0.06-3.0m/s for gas and 0.06-0.4m/s for oil. Several techniques have been used to analyze the output data of the two tomography techniques such as time series of cross-sectional averaged void fraction, Probability Density Function (PDF), image reconstruction, and liquid hold-up profile. The averaged void fractions were calculated from the output signal of the two measurement techniques and plotted as functions of the superficial velocity of the gas. The flow patterns were identified from the PDF of the averaged void fraction. In addition, it was found that both tomographic techniques are reliable in identifying the flow regimes in pipes.

Abstract:

Tension band wiring with cerclage wiring is most widely used for treating displaced patellar fractures. Although wire breakage is not uncommon, migration of a fragment of the broken wire is rare, especially migration into the knee joint. We describe here a rare case of migration of a wire fragment into the posterior septum of the knee joint after fixation of a displaced patellar fracture with tension band wiring and cerclage wiring. Although it was difficult to determine whether the wire fragment was located within or outside the knee joint from the preoperative plain radiographs or three-dimensional computed tomography (3D CT), we found it arthroscopically through the posterior transseptal portal with assistance of intraoperative fluoroscopy. Surgeons who treat such cases should bear in mind the possibility that wire could be embedded in the posterior septum of the knee joint.

Abstract:

Hyoid suspension is a procedure to stabilise the retrolingual space in obstructive sleep apnoea. Using the Hörmann technique, a steel wire is slung around the body of the hyoid and fixed to the upper rim of the thyroid cartilage. It was observed, however, that the steel wire may lie very superficially to the pharyngeal mucosa. Evaluation of computed tomography (CT) scans showed a mean distance between the hyoid and the pharynx of only 3 mm. A modification is presented by threading a steel wire through a hole that is drilled through the hyoid bone. Thus pharyngeal exposure of the steel ligature and possible perforation of the mucosa is avoided.

Abstract:

AbstractElectrical interconnects in integrated circuits have shrunk to sizes in the range of 20–100 nm. Accurate measurements of the dimensions of these nanowires are essential for identifying the dominant electron scattering mechanisms affecting wire resistivity as they continue to shrink. We report a systematic study of the effect of line edge roughness on the apparent cross-sectional area of 90 nm Cu wires with a TaN/Ta barrier measured by conventional two-dimensional projection imaging and three-dimensional electron tomography. Discrepancies in area measurements due to the overlap of defects along the wire's length lead to a 5% difference in the resistivities predicted by the two methods. Tomography of thick cross sections is shown to give a more accurate representation of the original structure and allows more efficient sampling of the wire's cross-sectional area. The effect of roughness on measurements from projection images is minimized for cross-section thicknesses less than 50 nm, or approximately half the spatial frequency of the roughness variations along the length of the investigated wires.

Abstract:

Femoral artery injury after femoral fracture fixation is a rare complication. Previous literature studies focused mostly on proximal femur fracture. We described a case of superficial femoral artery entrapment after internal fixation augmented with cerclage wire. An 80-year-old female underwent fixation with distal femur locking compression plate augmented with cerclage wire. Six hours after the operation, she developed pulseless limb and computed tomography angiogram showed femoral artery entrapped by cerclage wire. After vascular exploration and cerclage wire removal, the femoral artery returned to normal flow without further complication. We review available literature studies on vascular injury after cerclage wiring especially in the distal part of the femur, the so-called safe zone, for the great care needed before cerclage wiring and the importance of immediate diagnosis and treatment.

Abstract:

Two-phase flow behaviour and its flow patterns have a significant effect in many applications in industry. Oil-gas is one of the two-phase flow types that have many applications in petroleum and power stations. An oil-gas two-phase flow behaviour and flow patterns have been investigated in an inclined pipe using two different tomography sensors: Wire Mesh sensor (WMS) and Electrical Capacitance Tomography (ECT). A special experimental facility was designed and built to operate the tow-phase flow application in the inclined pipe with the various angle of inclination. A set of experimental data were collected using operating conditions which covered a two-phase flow range of superficial velocity of gas (Usl) from 0.05 to 0.52 m/s and superficial velocity of liquid (Usg) from 0.05 to 4.7 m/s at atmospheric pressure and room temperature. Three inclined angles to change the pipe’s inclination 45, 60, and 80-degree were applied in the experiments. The Comparison between the Wire Mesh Sensor (WMS) and Electrical Capacitance Tomography (ECT) was completed experimentally. The results revealed that there is a good agreement between the two sensors, however; the WMS had a higher frequency which was calculated 1000 frames per second compared with the ECT which worked at 200 frames per second.

Abstract:

Video-assisted thoracoscopy (VATS) is performed for diagnosis and treatment of peripheral lung nodules. Localization of peripherally located ground-glass opacities (GGOs) can be challenging. We report the results and usefulness of preoperative computed tomography (CT)-guided wire localization. Records for patients who underwent CT-guided wire localization prior to VATS resection for peripherally located GGOs were analyzed. Our technique for targeting the GGOs, complications, and histopathology of GGOs is reviewed. Forty patients (mean age 68 years) underwent pulmonary resections following CT-guided wire localization. The mean diameter of the GGO was 11.0 mm. The mean distance from the pleural surface to the peripheral margin of the GGO was 18.6 mm. Complications from the wire localization included pneumothorax in 5 patients (12.5%), none of whom required insertion of a chest tube; parenchymal hemorrhage in 3 patients (7.5%); and pleural effusion requiring chest tube drainage (unrelated to the wire) in 1 patient (2.5%). The mean operative time was 74 (range: 21-186 ) minutes. Pathological examination revealed lung malignancy in 36 patients (90%). The diagnostic yield was 100%. Preoperative CT-guided wire localization for solitary or multiple peripherally located GGOs allows for determination of histopathologic diagnosis and high diagnostic yield.
