Clinical Outcome of Aortic Root Replacement With Cryopreserved Aortic Valve Allografts
Cryopreserved heart and vascular allografts are major prostheses of choice in cardiac surgery today, used in variety of treatment situations. Right and left ventricular outflow tract reconstruction in congenital heart diseases, cases of infective endocarditis, mitral valve plasty, and aortic aneurysm of infective etiology are the major indications for allograft use. Saphenous vein grafts with s...
متن کاملCryopreserved Human Allografts for the Reconstruction of Aortic and Peripheral Prosthetic Graft Infection
Background: This study aimed to present cases with cryopreserved human allografts (CHAs) for vascular reconstruction in both aortic and peripheral infected prosthetic grafts. Materials and Methods: This is a single center, observational descriptive study with retrospective analysis. In all cases, the infected prosthetic graft material was completely removed. At discharge, patients were administ...
متن کاملAcute Regeneration and Chronic Acellular Transformation of Rabbit Cryopreserved Aortic Allografts
An analysis of rabbit cryopreserved aortic allografts excised on postoperative days (POD) 2, 5, 11, 60, 210, 360, and 720, as well as controls that were untransplanted native aortas and cryopreserved aortas, was performed. On POD2, the number of medial smooth muscle cells in the allografts was reduced to approximately 50%. Ki-67 analysis revealed that medial smooth muscle cells in the allograft...
متن کاملCryopreserved human aortic root allografts arterial wall: Structural changes occurring during thawing
BACKGROUND The aim of our experimental work was to assess morphological changes of arterial wall that arise during different thawing protocols of a cryopreserved human aortic root allograft (CHARA) arterial wall. METHODS The experiment was performed on CHARAs. Two thawing protocols were tested: 1, CHARAs were thawed at a room temperature at +23°C; 2, CHARAs were placed directly into a water b...
متن کامل[The clinical use of cryopreserved human skin allografts for transplantation].
BACKGROUND The biological recovery of human skin allografts is the gold standard for preservation in Skin Banks. However, there is no worldwide consensus about specific allocation criteria for preserved human skin allografts with living cells. A report is presented on the results of 5 years of experience of using human skin allografts in burned patient in the Skin and Tissue Bank at the "Instit...
