Abstract
PURPOSE This study aimed to investigate the effects of two different positions on lower extremity hemodynamics during robot-assisted laparoscopic radical prostatectomy (RARP) for prostate cancer. METHODS A total of 196 patients who underwent RARP in our hospital from February 2020 to March 2022 were included in this study. Among them, 98 patients who underwent surgery with the Trendelenburg position and split-leg position with calf reverse arch from March 2021 to March 2022 were assigned to the observation group, while 98 patients who underwent surgery with the Trendelenburg position and low lithotomy position from February 2020 to February 2021 were assigned to the control group. Using an ultrasound diagnostic instrument to detect the internal diameter, mean blood flow velocity, and mean blood flow volume of the left deep femoral vein at different times, such as the supine position (T0), after 5 minutes of placing the patient in the leg spilt or low lithotomy position (T1), after 5 minutes of pneumoperitoneum (T2), after 5 minutes of head-down tilt or head-down tilt and calf reverse arch (T3), 1.5 hours after the start of surgery (T4), before the removal of CO2 gas (T5), and before the patient left the operating room (T6). As well as the patency of deep venous blood flow in both lower extremities before leaving the operating room, RESULTS: After establishment of pneumoperitoneum, the internal diameter of the deep femoral vein increased significantly, while the mean blood flow velocity and mean blood flow volume decreased significantly in both groups(T0) (P<0.001). With the prolongation of surgical time, the impact on lower extremity hemodynamics in the observation group was smaller than that in the control group. From T2 to T6, the internal diameter of the femoral vein in the observation group was smaller than that in the control group, while the mean blood flow velocity and mean blood flow volume were increased compared to the control group (P<0.05). Before leaving the operating room, the patency of deep venous blood flow in the observation group was better than that in the control group (P=0.003). CONCLUSION Placing patients in the Trendelenburg position and split-leg position with calf reverse arch during RARP for prostate cancer has a smaller impact on lower extremity hemodynamics than the low lithotomy position, and can relatively reduce the risk of postoperative deep vein thrombosis.

Abstract
BACKGROUND The finding of concurrent deep venous reflux (DVR) when interrogating superficial venous reflux is common and might be a marker of more severe chronic venous insufficiency. However, the safety and clinical and patient-reported outcomes for patients undergoing superficial venous treatment in the presence of DVR remains underreported. Moreover, the factors associated with the persistence and disappearance of DVR after superficial vein treatment have not been evaluated. In the present study, we sought to address these questions. METHODS We performed a review of the institutional vascular quality initiative database from June 2016 to June 2021. Consecutive patient limbs were identified that had undergone a superficial venous intervention and had duplex ultrasound evaluations available. These patients were divided into those with and without DVR. Those with DVR were further reviewed for anatomic details and the persistence or resolution of DVR after the procedure. The primary outcome was the venous clinical severity score (VCSS) at a follow-up >3 months. The secondary outcomes included the incidence of any postoperative deep vein thrombosis or endovenous heat-induced thrombosis, differences in patient-reported outcomes, rate of resolution of DVR, and factors associated with DVR persistence. Both univariate analysis and multivariate logistic regression were applied. RESULTS Of the patients who had undergone superficial venous treatment, 644 patient limbs had had DVR and 7812 had not, for a prevalence of 7.6%. The DVR group was associated with a higher burden of chronic venous insufficiency. On univariate analysis, patient limbs, both with and without DVR, had improved significantly in the VCSS at <3 months of follow-up and were not significantly different. At >3 months of follow-up, the VCSS had again improved significantly compared with the VCSS at <3 months of follow-up. However, the difference between the two groups was statistically significant at the longer interval. The magnitude of improvement in the VCSS between the two groups at the longer follow-up were similar statistically (VCSS, 3.17 ± 3.11 vs 3.03 ± 2.93; P = .739). The HASTI (heaviness, achiness, swelling, throbbing, itching) score had similarly improved significantly in both groups but remained significantly higher in the DVR group during follow-up. On multivariate logistic regression, DVR was not associated with an increased VCSS at >3 months of follow-up. No intergroup difference was found in the incidence of postoperative deep vein thrombosis or endovenous heat-induced thrombosis. Of limbs with DVR, 40.8% no longer had evidence of detectable DVR at the latest follow-up venous duplex ultrasound, and DVR limited to a single segment was more likely than DVR in multiple segments to be no longer detectable. CONCLUSIONS Our results have shown that superficial venous procedures are safe and effective in patients with DVR, leading to improvements in clinical and patient-reported outcomes similar to those for patients without DVR. In a large proportion of the treated limbs, especially those with DVR in a single segment, no evidence of DVR was found after superficial venous intervention. Although patients with DVR will have a higher burden of chronic venous insufficiency, they still appear to derive significant benefit from superficial venous treatment.

Abstract
Femoral veins have been used as a substitute graft for limb bypass in selected patients. The long-term efficacy of deep-vein grafts in neoaortoiliac system reconstruction has been shown to be excellent but the efficacy in extremity bypass is still unclear. Here, we report a case of subclavian-to-brachial artery bypass surgery using a femoral vein graft in a chronically immunocompromised patient with previous kidney transplantation. The patient remains symptom-free at 5 years with a patent bypass without any complications, such as aneurysmal dilatation, recurrent infection, stenosis or harvested limb oedema. The femoral vein would be a good option for extremity bypass in patients with high-risk immune problems when other veins are not available.

Abstract
Tunneled central venous catheter (TCVC) placement is often an easy and uncomplicated procedure. As such, some clinicians pay little attention to the procedure, and different complications occurred. Catheter fragment loss in major vessels is a rare but serious complication of in situ catheter exchange with few reported cases in the literature. Once catheter fragments slip into a deep vein, endovascular retrieval should be attempted, due to its high success rate and minimal associated morbidity. A 37-year-old male patient underwent replacement of his temporary catheter with TCVC through a trans-right-internal-jugular-vein approach for maintenance of dialysis. As a major unintended outcome of the operation, a catheter fragment slipped into the right internal jugular vein, then migrated and lodged in the inferior vena cava. We retrieved it with a gooseneck snare without complications. We report the case hoping to emphasize on and raise awareness of the fact that catheter fragment loss is a completely evitable complication, provided the operator follows the correct safety measures and protocols. However, if catheter fragment loss occurred, the fragment should be retrieved as soon as possible. A gooseneck snare is an ideal option for retrieving catheter fragments that have migrated into deep veins.

Abstract
OBJECTIVES The mechanism by which compression therapy works is still discussed, especially at calf level. Whether lower limb deep vein diameters change under compression stockings is a matter of debate: no change versus great change. New study material helps to address this question. METHODS This was an experimental single centre controlled study on nine selected patients with mild to moderate superficial venous disease. A total of 34 deep vein segments were examined. A new hybrid (elastic + non-elastic materials) cuff pressure device enabled the deep vein diameter changes from baseline to occlusion similar to that which could be observed under stockings. The deep vein diameters were measured through the device with the patients in a standing position and their body weight distributed equally on both legs. This was compared to a 20-35 mm Hg medical compression stocking. The diameter change when patients put their whole body weight on the tested leg was also measured. RESULTS A pressure of 25.3 ± 6.4 mm Hg (mean, SD) was required to ovalise lower leg deep veins and a pressure of 43.1 ± 16.2 mm Hg (mean, SD) to occlude them. Both pressures were significantly different from baseline: p = .003 and p < .0001, respectively. No diameter reduction was achieved when the stockings were worn, and occlusion of deep veins occurred when the patients transferred their body weight onto the examined leg. CONCLUSION In the standing position, deep vein diameter reduction is not caused by compression stockings but may be due to the isometric muscle contractions required to support the patient's body weight.

Abstract
BACKGROUND Glossy balloons were used to enhance deep vein thrombolysis. However, thrombi tend to yield in the balloon dilatation due to their smooth surface. It may be preferable to enhance thrombolysis by using balloons with a rough surface, instead of balloons with a smooth surface. MATERIAL AND METHODS Four rabbits were used for the experiment and 60 blood clot samples were obtained, and the samples were randomly separated into one control group and four balloon-solubilised groups. Urokinase solution (5000 U/ml) was used as the thrombolytic drug. The balloon-solubilised groups were enhanced respectively by 1 atm and 2 atm pressurised glossy balloons, and 1 atm and 2 atm pressurised corn-shaped balloons. Thrombolysis rates and residual rates for different granularities of blood clots were calculated for comparasion. RESULTS Thrombolysis rates of the groups using corn-shaped balloons were higher than those of the groups using glossy balloons (p = 0.003 and p = 0.002). Residual rates of Φ ≥ 3.7 mm blood clots for the groups using corn-shaped balloons were lower than those for the groups using glossy balloons (p < 0.001 and p < 0.001). CONCLUSION Balloons could be used to enhance thrombolysis; under the same balloon dilatation pressure, thrombolysis rates when using corn-shaped balloons are better than those when using glossy balloons.
