One-year patency of a novel biorestorative polymeric coronary artery bypass conduit.

Interdiscip Cardiovasc Thorac Surg

December 2024

Cardiac Surgery Department, Sanatorio Italiano, Asunción, Paraguay.

Coronary artery bypass graft (CABG) surgery remains the gold standard in the treatment of complex coronary artery disease. Saphenous vein grafts (SVG) are commonly used for the non-left anterior descending artery. However, SVG failure rates in CABG surgery have been reported to be as high as 30% at 1 year and ∼50% at 10 years.

Background: Flow-through flaps (FTFs) are an advanced technique in which a free flap is anastomosed to the pedicle of another free flap to reconstruct extensive head and neck defects when recipient vessels are scarce.

Methods: A multi-institutional cohort of FTFs used for head and neck reconstruction were reviewed. For comparison, FTF outcomes were compared to free flaps that required vein grafts (VG) to reach distant recipient vessels.

Dr Hitha Antony, Post Graduation 3rd Year Student, Department of Physiology, All India Institute Of Medical Science (AIIMS), Bhopal, India; E-mail:

To assess and compare the sensory component of the saphenous nerve in Coronary artery disease (CAD) patients undergoing Coronary artery bypass graft (CABG) with great saphenous vein graft pre and post-CABG. An observational longitudinal study evaluating the effect of surgery on the saphenous nerve involved 32 CAD patients undergoing CABG. This study was carried out jointly by the Department of Physiology and the Department of Cardiothoracic Vascular Surgery (CTVS) at All India Institute of Medical Sciences, Bhopal, India from November 2022 to January 2024.

Major vessel invasion, particularly involving the portal and superior mesenteric veins, poses significant challenges during the radical resection of hepatobiliary and pancreatic cancers. Oncovascular surgery is essential for curative outcomes, and often requires portomesenteric vein reconstruction. Techniques, such as lateral venorrhaphy, patch repair, end-to-end anastomosis, and interposition grafting, have been employed.

Introduction: Initial surgical revascularization has a recognized primary role in patients with critical limb-threatening ischemia with a high-quality great saphenous vein for conduit. However, approximately one-third of lower extremity vein grafts develop lesions threatening graft patency. Traditional treatments have limitations, highlighting the need for innovative solutions.
