Myxofibrosarcoma (MFS), a subtype of aggressive soft tissue sarcoma, primarily arises in the extremities and trunk but rarely in the retroperitoneum.

We present a strategic plan for achieving R0 resection of a large retroperitoneal MFS. Firstly, the entire infrahepatic inferior vena cava (IVC) was replaced with a tube graft following separation of the IVC from the aorta, division of the right renal artery, and transection of both proximal and distal IVC, including its division from the renal veins. The tumor was then removed en bloc with the IVC, right kidney, and portions of the psoas and quadriceps muscles.

It is primarily characterized by stenosis or occlusion of peripheral arteries due to atherosclerosis. The infrainguinal segment is frequently involved in PAD, making revascularization decisions for infrainguinal arterial disease (IAD) complex. Multiple factors, including the patient's condition and anatomical characteristics, must be carefully considered when determining the optimal treatment approach. Once these factors are evaluated, the first revascularization strategy is selected from among open, endovascular, or hybrid modalities, based on high-level evidence. Endovascular therapy is widely accepted as the standard treatment for simple IAD, with balloon angioplasty and stenting being the commonly used techniques. However, advancements in endovascular techniques have enabled the treatment of increasingly complex lesions. Additionally, drug-based technologies have enhanced the durability of treatment outcomes, including improvements in primary patency rates and freedom from target lesion revascularization. Similar to surgical endarterectomy, percutaneous atherectomy has been developed to remove atherosclerotic plaques and mitigate intimal calcification. The purpose of this paper is to present an algorithm for revascularization of IAD through a comprehensive review of studies comparing the outcomes of various treatment modalities.</p>","PeriodicalId":52311,"journal":{"name":"Vascular Specialist International","volume":"41 ","pages":"6"},"PeriodicalIF":0.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11913610/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
