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: Percutaneous transluminal angioplasty (PTA) is being increasingly used as a primary treatment for critical limb ischemia (CLI). The aim of this study was to evaluate the results of performing PTA for the superficial femoral arteries (SFA) for treating CLI or claudication. METHOD: From April 2003 to February 2007, PTA of the SFA was performed on 44 limbs in 39 patients. The mean follow-up was 10.1 months. RESULT: The demographic features included a mean age of 67.6 years; the patients were 89.7% males, and CLI was present in 56.8% of the subjects. The lesions were classified according to the TransAtlantic Inter-Society Consensus (TASC) as A (6.8%), B (40.9%), C (31.8%) and D (20.5%). PTA was confined to the SFA in 29 limbs (65.9%), and 15 patients (34.1%) underwent concurrent interventions in other anatomic locations. The SFA interventions included angioplasty only in 9 limbs (20.5%) and at least one stent in 35 limbs (79.5%). Clinical success was obtained in 33 limbs (75.0%) and limb salvage for CLI was achieved in 80% limbs (20/25 limbs). The complications included two access site hematomas and six intimal dissections. Interval conversion to bypass surgery was done in 5 limbs and major amputation was performed in 4 limbs. One patient died perioperatively after bypass surgery. The primary patency rates were 83.0% at 3 months, 78.9% at 6months and 72.3% at 12 months. The variables associated with the inferior primary patency rate by univariate analysis included CLI, the type of lesions (TASC A/B vs C/D), and the length of the treated lesions (P=0.01, P=0.008 and P=0.007, respectively). The modified runoff scoring system was predictive of PTA failure (P=0.003). CONCLUSION: PTA of the SFA for treating CLI or claudication is feasible and safe, and it provides acceptable clinical results. It would be appropriate to use PTA as the initial treatment option for chronic superficial femoral occlusive disease.

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.

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.
