The small saphenous vein (SSV) is an important graft in limb salvage surgery. It is frequently translocated for bypass surgery. Sometimes, the use of the SSV as an in-situ graft for posterior tibial artery or peroneal artery reconstruction offers the advantages of reduced vein graft injury and improved patency. Recently, saphenous vein mapping through computed tomography (CT) volume rendering technique offers a great quality view to the surgeon. We experienced a patient in whom a CT image with volume rendering technique revealed an aberrant SSV connected with the great saphenous vein at the medial malleolus level. This case indicates that an aberrant SSV may be successfully used as an in-situ conduit for bypass to the dorsalis pedis artery. Here, we present the case of a popliteal-to-dorsalis pedis in-situ vein bypass using a LeMaitre valvulotome (LeMaitre Vascular Inc., USA) under mapping of the aberrant SSV by CT volume rendering technique.

PURPOSE: The purpose of this study is to compare and analyze the results of primary and secondary patency rates and limb salvage rates in DM (Diabetes Mellitus) and Non-DM patients with atherosclerosis in the lower extremity after arterial reconstruction. METHODS: A retrospective study was done by reviewing admission notes and follow up records of 95 atherosclerotic limbs which had infrainguinal arterial reconstruction due to claudication induced severe impediment and limb threatening ischemia (reat pain, minor and major tissue loss). Kaplan-Meier survival analysis was used in the comparison of the primary, secondary patency rates and limb salvage rates, and statistical examination was handled by the Log-Rank significance test. RESULTS: 1 and 3 year primary patency rates were 76.0% and 65.6% each in the DM group and 63.9% and 56.5% each in the Non-DM group. 1 and 3 year secondary patency rates were 80.0% and 69.7% in DM patients and 81.1%, 73.9% each in Non-DM patients. The 1 and 3 year limb salvage rates of DM patients were 83.8% and 72.6% while Non-DM patients revealed a 84.9% and 77.8%. CONCLUSION: Aggressive arterial reconstruction is recommended as well, in DM patients with atherosclerosis in the lower extremity, considering the insignificant differences in the risk of surgery as well as the primary, secondary patency rates and limb salvage rates.

PURPOSE: To analysis of the clinical aspects of axillofemoral (AXFBG) and aortofemoral bypass (AOFBG) for aortoiliac occlusive disease. METHODS: Between June 1996 and May 2001, 23 patients underwent AXFBG or AOFBG for lower extremity ischemia caused by aortoiliac occlusive disease at Samsung Medical Center. The decision to perform AXFBG or AOFBG was based on an assessment of surgical risk and the patient's preference. We retrospectively analyzed the preoperative clinical status, risk factors and distal runoff scores affecting the patency rate as well as the clinical outcome following surgery. RESULTS: We performed 10 AXFBGs and 13 AOFBGs. The mean age was 67.8 years in AXFBG patients and 57.4 years in AOFBG patients. Limb salvage as an indication for surgery included 8 (80%) cases with AXFBG, as compared to 13(100%) cases with AOFBG. The mean follow-up period was 20.7 months in AXFBG and 21.8 months in AOFBG. The clinical improvement following surgery was statistically higher with AOFBG. The one-year and 2-year primary patency rates in AXFBG were 100% and 82% retrospectively. All of the grafts of AOFBG were patent during this follow-up period. CONCLUSION: The clinical improvement was higher with AOFBG as compared to AXFBG. However AXFBG is a safe practice in high-risk patients.

Phlegmasia cerulea dolens (PCD) is a medical emergency that can lead to venous gangrene of the lower extremity. Early diagnosis and prompt treatment is crucial for limb salvage. There are two treatment options (endovascular or surgical). In the endovascular era, catheter-directed thrombolysis is the treatment of choice to achieve venous outflow. However, surgical thrombectomy is indicated in certain cases. The authors report successful surgical thrombectomy in a 75-year-old man with PCD and review the treatment of PCD.

PURPOSE: Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. MATERIALS AND METHODS: We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from March 2012 to November 2016. RESULTS: Critical limb ischemia was common (63.6%) indication of bypass surgery and most (90.9%) of the patients had history of failed previous treatment including endovascular treatment (36.4%) and bypass surgery (72.7%). At the 2 years after graft implantations, primary patency and amputation-free survival of below-knee bypasses using composite graft were 73% and 76%, respectively. CONCLUSION: Infrainguinal arterial bypasses with composite graft had an acceptable patency. In patients without other alternative conduits for revascularization, bypass with a composite graft can be an option.

BACKGROUND AND OBJECTIVES: With recent advances in equipment and techniques, infrapopliteal angioplasty has shown results that are comparable to those of surgical bypass in patients with critical limb ischemia (CLI). In this study, we evaluated the efficacy and the feasibility of infrapopliteal angioplasty in patients with CLI. SUBJECTS AND METHODS: Between March 2002 and May 2008, infrapopliteal angioplasty was performed on 118 limbs of 101 patients (79 males; mean age 66 years) with CLI (Rutherford category 4, 5 or 6). Freedom from reintervention, limb salvage, and overall survival were analyzed. RESULTS: The median follow-up duration was 30 months. Initial technical and clinical success rates were 69.5% and 83.1%, respectively. No major complication requiring surgical intervention developed after angioplasty. Among 82 limbs with initial technical success, the rate of freedom from any reintervention at 2 years was 70.7% and that from limb salvage was 97.6%. Young age and Rutherford category 6 at initial presentation were independent predictors associated with poor 2 year primary patency in these patients with CLI. Overall survival at 1 year was 86.4% and that at 2 years 76.3%. A history of cerebrovascular accident was an independent predictor associated with poor 2 year survival in these patients. CONCLUSION: Infrapopliteal angioplasty as a primary choice of treatment in CLI patients showed favorable clinical outcomes and feasibility.
