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: We wanted to define the appropriate treatment modalities for Trans-Atlantic Inter-Society Consensus (TASC) II C and D femoro-popliteal lesions. So we compared the primary patency rate and several clinical factors between percutaneous balloon angioplasty with or without stenting (PTA/S) and bypass surgery (BP). METHODS: We reviewed the medical records of patients who underwent BP or PTA/S for TASC II C (BP-C, PTA/S-C) and D (BP-D, PTA/S-D) femoro-popliteal lesions from March 2001 to May 2009. We analyzed the primary and secondary patency rates, and the major limb salvage rates. RESULTS: Eighty two limbs in 74 patients (mean age: 68.7+/-10.2 years, males: 82.9%) were treated (PTA/S-C: 18, PTA/S-D 19: BP-C 12, BP-D 33). The mean follow-up duration was 30.0+/-19.0 months. The twenty four month primary patency rates was 82.4% for PTA/S-C and 73.3% for BP-C (P=0.876), and 45.3% for PTA/S-D and 66.6% for BP-D (P=0.034). The twenty four month secondary patency rates were 88.2% for PTA/S-C and 73.3% for BP-C (P=0.669), and 54.7% for PTA/S-D and 73.3% for BP-D (P=0.077). The twenty four month major limb salvage rates were 100.0% for PTA/S-C and 75.0% for BP-C (P=0.030) but there were no statistical differences between the TASC II D groups (P=0.377). CONCLUSION: Bypass surgery is a preferred initial therapeutic option for TASC II D femoro-popliteal lesions. However, several clinical factors must be carefully considered when selecting the primary treatment modality for TASC II C lesions.

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.

We retrospectively analysed plain radiographs and MR imaging of 16 conventional osteosarcoma cases(8 children, 8 adults) which underwent amputations or limb salvage operations. Pathologic correlation was performed with gross and microscopic sections to evaluate 1) whether the open epiphyseal plate can function as a barrier against transphyseal spread of osteosarcoma and 2) the diagnostic value of MR imaging for the detection of the detection of the epiphyseal involvement of osteosarcoma. In children with open epiphyseal plates, conventional radiographs suggested transphyseal tumor growth in one of eight cases(12.5% and MR imaging in seven cases(87.5%). Pathologic examination confirmed epiphyseal involvement in six of seven cases noted with MR imaging(75%). On the the other hand, in adult patients with closed epiphyseal plates, conventional radiographs showed transphyseal tumor growth in six of eight cases(75%), while MR imaging and pathologic exam demonstrated tumor invasion in all cases(100%). We conclude that open epiphyseal plate does not function as and effective barrier against tumor extension, and MR imaging is an excellent method in detecting the extent of transphyseal tumor growth.
