AI Article Synopsis
- A retrospective study evaluated the effectiveness of popliteal-to-distal bypass surgery in patients over a period from 1990 to 2001, focusing on outcomes for diabetic versus nondiabetic patients and elective versus emergency procedures.
- Primary patency at 30 days was 88.7%, with long-term rates showing 57% primary and 61% secondary patency at five years, alongside a 64% limb salvage rate.
- No significant difference was found between diabetic and nondiabetic outcomes, but elective surgeries had better results compared to emergency procedures, and great saphenous vein grafts performed better than PTFE grafts.
Article Abstract
A retrospective study was carried out to examine the patency and limb salvage rates of popliteal-to-distal bypass and compare the results of diabetic to those of nondiabetic patients and elective versus emergency procedures. From January 1990 to December 2001, 71 popliteal-to-distal bypasses were performed. Indications for surgery were rest pain, tissue loss, and acute ischemia, including extensive post-traumatic tibial lesions. Survival, graft patency, and limb salvage rates were determined according to the life-table method. The log-rank test was used to compare diabetic versus nondiabetic patients, elective versus emergency procedures, and saphenous vein bypass versus PTFE bypass. Postoperative primary patency, secondary patency, and limb salvage rates at 30 days were 88.7%, 91.4%, and 87%, respectively. Postoperative mortality was 2.8%, with one case of acute myocardial ischemia and one multiorgan failure. Life-table analysis showed primary and secondary patency rates of 57% and 61%, respectively, a limb salvage rate of 64%, and survival of 77% at 5 years Log-rank testing showed no statistical difference between diabetic and nondiabetic patients, whereas a statistical difference was observed in elective versus emergency procedures (p < 0.005) and great saphenous vein versus PTFE graf (p < 0.05). These results show that popliteal-to-distal bypass is a safe and effective procedure with good long-term patency and limb salvage rates in selected cases.

Limb salvage prediction in peripheral artery disease patients using angiographic computer vision.

Department of Vascular Surgery, University Hospital Leipzig, Leipzig, Germany.
Background: Peripheral artery disease (PAD) outcomes often rely on the expertise of individual vascular units, introducing potential subjectivity into disease staging. This retrospective, multicenter cohort study aimed to demonstrate the ability of artificial intelligence (AI) to provide disease staging based on inter-institutional expertise by predicting limb outcomes in post-interventional pedal angiograms of PAD patients, specifically in comparison to the inframalleolar modifier in the Global Limb Anatomic Staging System (IM GLASS).
Methods: We used computer vision (CV) based on the MobileNetV2 model, implemented via TensorFlow.
Limb salvage surgery has become the primary means of treatment for patients with malignant tumors of the extremities and pelvis. For these patients, endoprostheses have become the principal means to reconstruct the extremity following an oncologic resection because they offer an off-the-shelf-option that is modular, cost effective, and durable. As with other forms of arthroplasty, several modes of failure can occur, with infection being common.

Objective: The impact of great saphenous vein harvest technique on infrainguinal bypass outcomes remains a matter of debate, with no robust evidence favoring a specific technique over the other. This study aims to compare the outcomes of open vein harvest with endoscopic vein harvest in patients undergoing infrainguinal bypass surgery.
Methods: Patients who underwent an infrainguinal bypass from a femoral origin using a single-segment great saphenous vein between 2011 and 2023 were identified in the Vascular Quality Initiative infrainguinal bypass module.
Comparison of Patient-Reported Outcomes after Local Flap Coverage versus Amputation for Complex Lower Extremity Trauma.

Division of Plastic Surgery, Indiana University School of Medicine, Indianapolis, Indiana, United States.
There is a paucity of patient-reported outcomes (PROs) data in lower extremity salvage. Limb salvage can often be achieved with the use of local muscle flaps or fasciocutaneous flaps. The purpose of this study was to compare PROs of patients who underwent lower extremity salvage using local fasciocutaneous flaps or muscle flaps to lower extremity amputation.

Background/aim: Scapular osteosarcoma is a rare malignancy, and the understanding of its optimal treatment strategies and long-term outcomes remains limited. The purpose of the current study was to evaluate our institutional experience.
Patients And Methods: We reviewed 14 patients (8 females, 5 males; mean age 44±17 years) treated for scapular osteosarcoma from 1985 to 2022.
