Stent patency rates and prognostic factors of endovascular intervention for iliofemoral vein occlusion in post-thrombotic syndrome.

Objective: Post-thrombotic syndrome (PTS), an important complication of deep venous thrombosis (DVT), adversely affects patients' quality of life. Endovascular intervention in PTS can relieve symptoms rapidly with high therapeutic value. This study mainly focuses on how to improve postoperative stent patency rates and aims to find prognostic factors impacting patency.

MicroRNA profile of circulating CD4 T cells in aged patients with atherosclerosis obliterans.

Background: To evaluate the specificity of the expression patterns of microRNAs (miRNAs) in circulating CD4 T cells in aged patients with atherosclerosis obliterans (ASO).

Methods: A comprehensive miRNA expression study was conducted using a miRNA microarray of CD4 T cells isolated from peripheral blood mononuclear cells (PBMCs) of 33 patients with ASO and 24 healthy donors. A t test was used for statistical analysis, and the average linkage method was used for hierarchical clustering.

Comparison of the Bifurcated Graft Reconstruction and Aortic Stump Closure in Open Surgical Conversion After Endovascular Aneurysm Repair.

Background: The optimal management of the aortic stump in open surgical conversion (OSC) after Abdominal aortic aneurysm (AAA) endovascular aneurysm repair (EVAR) is debated. Therefore, we aimed to compare the efficacies and safety between the bifurcated prosthetic vascular graft in situ stump reconstruction (p-graft ISSR) and aortic stump closure (ASC) in OSC.

Methods: We analyzed 973 elective AAA patients admitted from January 01, 2001 to December 31, 2020, at the First Affiliated Hospital of Sun Yat-sen University.
