Perigraft reaction and incorporation of porcine and bovine pericardial patches.

Objectives: Bovine and porcine pericardial patches are frequently used in cardiothoracic and vascular surgery. There are no guidelines recommending the usage of these patches for particular surgical approaches. However, these 2 materials supposedly possess different properties.

Neither Isolated Hepatic Arterial Clamping nor Hepatic Arterial Ligation Induce Ischemic Type Biliary Lesions in Rats.

BACKGROUND Ischemic type biliary lesions (ITBL) is a troublesome complication after liver transplantation. Little is known about its pathogenesis and there is particularly little data about morphological alterations. Prolonged warm and cold ischemia time and reduced hepatic arterial perfusion are risk factors leading to ITBL.

Perigraft vascularization and incorporation of implanted Dacron prostheses are affected by rifampicin coating.

Background: Prosthetic vascular grafts are increasingly implanted to replace damaged arteries. However, their microbial contamination is highly problematic and often results in devastating clinical complications. To reduce the risk of infection, Dacron grafts may be coated with rifampicin.

Preconditioning by cilostazol protects against cold hepatic ischemia-reperfusion injury.

Background: In liver transplantation, prolonged cold storage and post-transplant reperfusion are associated with endothelial inflammation, organ dysfunction, and graft failure. We herein studied whether cilostazol, a phosphodiesterase-3-inhibitor, attenuates post-ischemic liver injury after prolonged cold storage.

Material And Methods: Sprague-Dawley rats were assigned to 5 groups (n=6 each): sham animals (cold storage time (CST): 1 h), vehicle-treated (NaCl 0.

Cilostazol improves hepatic blood perfusion, microcirculation, and liver regeneration after major hepatectomy in rats.

Major hepatectomy or small-for-size liver transplantation may result in postoperative liver failure. So far, no treatment is available to improve liver regeneration. Herein, we studied whether cilostazol, a selective phosphodiesterase III inhibitor, is capable of improving liver regeneration after major hepatectomy.
