Endovascular therapy for iatrogenic occlusion of the popliteal artery after complex total knee arthroplasty: A case report.
J Vasc Surg Cases Innov Tech
April 2025
Department of Vascular Surgery, St Franziskus Hospital, Münster, Germany.
Iatrogenic arterial injury is an infrequent but limb-threatening complication of total knee arthroplasty (TKA). Open surgical reconstruction may not always be feasible or optimal, particularly in patients who have recently just undergone complex TKA procedures. In this report, we describe the treatment of a patient who developed popliteal artery occlusion following a complex TKA procedure performed the previous day.

Background: Lipopolysaccharide (LPS)-induced apoptosis of lung microvascular endothelial cells (ECs) is the main reason of lung edema and acute lung injury (ALI) in septic conditions. Telocytes (TCs) are a distinct type of interstitial cells found around the lung microvasculature, which may protect ECs through the release of shed vesicles. However, whether TCs protect against LPS-induced EC apoptosis and ALI has not been determined.

Department of Ophthalmology, Sichuan University West China Hospital, Chengdu, Sichuan Province, China.
Objective: To investigate the short-term blood flow changes and image features of the retina and choroid in patients who underwent carotid artery revascularization (CAR) for severe carotid artery stenosis using widefield swept-source OCT angiography (OCTA).
Design: Prospective study.
Participants: This prospective study included 112 eyes (56 eyes on the ipsilateral side and 56 eyes on the contralateral side) of 56 participants with severe carotid artery stenosis.
Elevated phosphate levels in CKD - a direct threat for the heart.

Elevations in systemic phosphate levels, also called hyperphosphatemia, occur in chronic kidney disease (CKD) and during the normal aging process and are associated with various pathologies, such as cardiovascular injury. Experimental studies suggest that at high serum concentrations, phosphate can induce osteogenic differentiation of vascular smooth muscle cells and contribute to vascular calcification. However, the precise underlying mechanism leading to cardiovascular injury is not well understood.

Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal vascular malformations. Multiple SDAVFs are unusual and can occur either synchronously or metachronously, as reported in the literature. We report on the unusual case of a woman with three separate SDAVFs, which were surgically treated within the same setting; the postoperative course was characterised by unexplained repeated haematoma formation within the surgical sites.
