Limb salvage prediction in peripheral artery disease patients using angiographic computer vision.
Vascular
January 2025
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.
Indian J Plast Surg
December 2024
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.

January 2025
Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN, U.S.A.;
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.
