Objective.The use of the axillary artery as an access site has lost favor in percutaneous intervention due to the success of these procedures from a radial or brachial alternative. However, these distal access points are unable to safely accommodate anything larger than a 7-French sheath. To date no studies exist describing the size of the axillary artery in relation to the common femoral artery in a patient population. We hypothesized that the axillary artery is of comparable size to the CFA in most patients and less frequently diseased.Methods.We retrospectively reviewed 110 CT scans of the thoracic and abdominal aorta done at our institution to rule out aortic dissection in which the right axillary artery, right CFA, left axillary artery, and left CFA were visualized. Images were then reconstructed using commercially available TeraRecon software and comparative measurements made of the axillary and femoral arteries.Results.In 96 patients with complete data, the mean sizes of the right and left axillary artery were slightly smaller than the left and right CFA. A direct comparison of the sizes of the axillary artery and CFA in the same patient yielded a mean difference of 1.69 mm ± 1.74. In all patients combined, the mean difference between the axillary artery and CFA was 1.88 mm on the right and 1.68 mm on the left. In 19 patients (19.8%), the axillary artery was of the same caliber as the associated CFA. In 8 of 96 patients (8.3%), the axillary artery was larger compared to the CFA.Conclusions.Although typically smaller, the axillary artery is often of comparable size to the CFA, significantly less frequently calcified or diseased, and in almost all observed cases large enough to accommodate a sheath with up to 18 French.

Abstract Objective To compare the histopathology of patent and nonpatent microvascular anastomosis using rat femoral artery end-to-end anastomosis model. Materials and Methods In 15 Sprague–Dawley rats, end-to-end anastomosis was performed on the right femoral artery. The classical method was used in four cases and one-way up method in 11 cases. The animals were sacrificed after 2 weeks and the anastomosis was subjected to histopathology. The pathological changes in patent and nonpatent cases were compared. Results The immediate patency rate and delayed patency (after 2 weeks) rate was 86.7% and 66.7%, respectively. The mean follow-up was 3 months. At sacrifice, 5/15 anastomosis were not patent. Marked subintimal thickening was noted in ⅘ (80%) of the nonpatent group, which was absent in the patent group. Severe loss or fibrosis of tunica media and marked adventitial inflammation were noted in all nonpatent cases (5/5, 100%). As much as ⅘ of the nonpatent cases had poor or indeterminate apposition; in contrast, good apposition was seen in 6/10 (60%) of the patent group. The mean clamp time and mean suturing time were significantly longer in the nonpatent group (69.2 minutes and 53.8 minutes, respectively) as compared with the patent group (48.8 minutes and 31.8 minutes, respectively). A single case that was initially nonpatent was found to have recanalized at 6 months. Conclusion Minimal intimal injury and reaction, minimal thinning of tunica media, mild-to-moderate adventitial changes, good apposition, and equidistant sutures were associated with a successful microvascular anastomosis. Short duration of vessel clamping time and suturing comes with experience and dedicated practice in a skills laboratory.

Endarterectomy is an effective intervention to remove the atheromatous plaque in the inner lining of the artery, aiming to revascularize the occluded/stenosed vessel in patients with peripheral arterial occlusive disease (PAOD). The most common wound-related complication is postoperative bleeding, followed by infection, hematoma, and seroma. However, hematoma complications with air surrounded have rarely been reported in clinical cases. Case presentation: A 90-year-old female patient visited our emergency department because of a rapidly growing hematoma with pulsatile bleeding over her right groin area. She had received bilateral percutaneous transluminal angioplasty with endarterectomy for PAOD one month prior. A point-of-care ultrasound revealed a large hypoechoic mass, with a dirty shadow on the right groin area. Computed tomography angiography showed a hematoma over her right femoral region, with free air surrounding the right femoral artery. Angiography revealed an irregular shaped lesion on the right femoral artery without contrast extravasation. The patient was diagnosed with right-femoral post-endarterectomy infection with infected hematoma, with the inclusion of air. She underwent urgent excision and repair of the right femoral artery infectious lesion, debridement of the infectious hematoma and stenting of the right external iliac artery, common femoral artery and superficial femoral artery.

INTRODUCTION The sciatic artery represents the earliest embryological blood supply to the lower extremity. It regresses after the 3rd month of embryologic development. The proximal part of the sciatic artery eventually persists as the inferior gluteal artery. Rarely, however, it persists into adulthood when it is frequently associated with numerous possible complications (aneurysm formation, embolism, nerve compression, rupture, thrombosis). CASE OUTLINE In March 1996, a 48-year-old male was admitted for angiography of the blood vessels of the right inferior extremity, before an elective orthopaedic procedure. Arteriography of the right leg was done in a usual manner through the right common femoral artery in order to get an angiogram of the popliteal trifurcation and crural arteries. However, on the first field we noticed a hypoplastic superficial femoral artery, as well as a huge persistent sciatic artery (PSA) originating from the internal iliac artery running distally and overlapping the deep femoral artery. There were no aneurysm and stenotic changes of PSA. CONCLUSION If clinical condition is stable, follow-ups at 12 months intervals should be done by means of ultrasound. The therapeutic decisions also depend on complete or incomplete PSA.

Introduction. Heart injuries can be classified as penetrating and non-penetrating (blunt). Penetrating wounds are usually caused by stabbing with a piercing object, weapon or projectiles - missiles. The right atrium is damaged in most cases, because of its anatomical position - making the most of the anterior side of the heart. Morbidity caused by stabbing injuries to the heart is 20%-30%, while piercing wounds cause 30%-60% of deaths. Case report. A 28-year-old patient was admitted to our clinic with acute ischemia of the extremities. Angiography revealed a bullet in the right common femoral artery, occluding it. The patient denied having any piercing or shooting wound to his leg, but he said that four years before he had been shot to his chest. Echocardiography revealed an atrial septal defect of secondary type. An event reconstruction revealed that, four years after shooting, the bullet was displaced from the heart to the right common femoral artery. Conclusion. This case report is unique because of the rare type of injury, time that passed from the injury, the way bullet entered the artery (via atrial septal defect) and especially the success of both surgical procedures (embolectomy and repair of atrial septal defect).

Abstract Background The most common vascular access for structural cardiac interventions such as transcatheter aortic valve implantation (TAVI) is the common femoral artery (CFA). Depending on the procedure CFA puncture has to be performed not only unilaterally, but also bilaterally. Since incorrect localization of femoral access can lead to severe vascular complications, specific knowledge about the exact position of the CFA bifuraction is helpful. Such information might be systematically obtained from pre-TAVI CT scans. Methods We performed a retroperspective analysis of consecutive contrast-enhanced pre-TAVI CT angiography data sets (n=1000) to determine the CFA bifurcation localization relative to the femoral head and the correlation to contralateral CFA bifurcation location. Results The site of the CFA bifurcation was in 67.2% below the femoral head (−−), in 24.3% within the lower third of the femoral head (−), in 7.4% in the mid (0) and in 1.2% within the upper third (+) of the femoral head. Bifurcations above (++) the femoral head were not detected. CFA bifurcations below the femoral head showed the highest prevalence within men and women in all age groups (50–59, 60–69, 70–79, 80–89, 90–99 years). Bilateral agreement of CFA bifurcations was observed in only 69.3% and was independent of one-sided hip replacement (agreement 72.7%) or two-sided hip replacement (agreement 78.7%). A congruent contralateral left CFA bifurcation below the femoral head could be predicted in 80.6%, whereas CFA bifurcations within the lower and upper margins of the femoral head were congruent in only 65.7% (of these, 49.2% for the lower third, 29.7% for the mid and 36.4% for the upper third). Conclusion In conclusion, punctures within the upper third of the femoral head will provide an ideal puncture site in at least 97% of cases, independent of age, sex, or previous hip replacement.

Abstract We evaluated feasibility of the newly-developed 3D printed training module for the navigation during retrograde intrarenal surgery. Two specialists provided orientation to all trainees. The 3D printing model consisted of eight calyces in each kidney. One navigation time started from the moment when the endoscope entered into the ureter. After navigation was completed, the navigation time was recorded. The goal was to perform ten times of navigation for each side, starting from the right or the left side at random. After the experiment, all trainees were asked to fill out a questionnaire. The average of training period of all 17 trainees was 3.05 ± 1.80 years. The average navigation time of 308 trials was 153.4 ± 92.6 sec. The maximum and minimum navigation time were 354.3 ± 177.2 sec and 80.1 ± 25.6 sec. The mean navigation time of the first and the last trials of all trainees significantly decreased from 251.4 ± 108.0 sec to 93.9 ± 33.2 sec. The average of reduction in navigation time was 201.3 ± 133.3 sec. Almost all trainees were satisfied with the training. The newly-developed 3D printing navigation training module seems to be effective.

1. Pressures on the right and left sides of the tails of swimming bluefish were measured and found to have a range of +5.9 to - 5.9 cm H2O. The pressures were resolved into their forward and lateral vectorial components of force to allow calculation of forward and lateral force and power at speeds ranging from 0.26 to 0.87 m/s. 2. The peak to peak changes in force of acceleration of the body, measured with a forward accelerometer averaged 209 g or 2.05 N at 0.48 m/s, and were compared with the maximum to minimum excursions of forward tail force averaging 201 g or 1.97 N at the same speed. The mean difference was 8 g, s.d. of the mean difference ± 29, s.e. of mean difference ± 10 g. 3. Mean tail thrust was calculated as the time average of tail force in the forward direction. It averaged 65 g, or 0.64 N, at 0.48 m/s. The mean forward power was 0.34 N m/s at 0.48 m/s. The drag of the gauges and wires accounted for 10% of this figure. 4. The mean lateral power of the tail was 1.28 N m/s at a mean speed of 0.48 m/s. 5. The propulsive efficiency of the tail, calculated as the ratio of forward power to forward plus lateral power, was found to be 0.20 s.d. ±0.04, s.e. ±0.01 and was not related to speed. This suggests that 80% of the mechanical power of the tail was wasted. Turbulence in the water may have contributed to this large drag and low tail efficiency.
