Free Functional Muscle Transfer in Brachial Plexus Injury Patients With Subclavian Artery Injury Using Arteriovenous Loop Grafts.
Microsurgery
January 2025
Department of Orthopaedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Background: Free functional muscle transfer (FFMT) for brachial plexus injury (BPI) requires adequate donor arterial flow for successful anastomosis. However, concomitant BPI and subclavian artery injury are not uncommon. Arteriovenous (AV) loop graft is one of the methods used to extend vessels to areas with vascular depletion.

Article Synopsis
- The study investigated how different treatments (balloon angioplasty vs. drug-coated balloons) affect the changes in blood vessel tissues following arteriovenous fistula stenosis in pigs with chronic kidney disease.
- Significant differences in tissue composition were observed, with drug-coated balloons leading to lower neointimal growth and higher endothelial cell counts compared to standard angioplasty.
- The findings suggest that using drug-coated balloons may improve vessel healing and reduce complications over time, as shown by varied immune cell responses and tissue growth patterns.

Electronic address:
Background: Hereditary hemorrhagic telangiectasia (HHT) is characterized by abnormal blood vessel formation. One treatment for HHT-related arteriovenous malformations (AVMs) is sclerotherapy, which collapses the blood vessels by irritating the endothelial lining.
Methods: This case series describes two HHT patients undergoing in-office sodium tetradecyl sulfate sclerotherapy for non-nasal telangiectasias and AVMs.
Venous aneurysm leading to fatal pulmonary thromboembolism with a history of a remote stab wound of the extremity.
J Forensic Sci

University of New Mexico Department of Surgery, MSC1056101, University of New Mexico, USA.
Venous aneurysms are rare, and their incidence is unknown. External iliac vein aneurysms are even more rare with only 50 case reports published from 1950 to 2018. We present a case of an individual who died suddenly from a pulmonary thromboembolic event due to an external iliac vein aneurysm formed by a remote penetrating injury.

Recently intermittent negative pressure has emerged as a potential treatment in vascular disease and has similarities with established experimental interventions such as lower body negative pressure. The direct, local influences of either method upon intravascular pressure still require some clarification however, particularly in the immediate moments following onset. We investigated the acute intravascular pressure responses to intermittent cycles of negative pressure in the supine and sitting postures.
