Abstract
Our current approach towards total arch replacement includes the following: (1) innominate vein mobilization, (2) no neck vessel taping, and no dissection of the vagal nerve, (3) meticulous selection of arterial cannulation site and type of arterial cannula, (4) antegrade cerebral perfusion(ACP)for neuro-protection, utilizing three balloon-tipped cannular from inside the arch, (5) whole-body hypothermia with minimal tympanic temperatures between 20 and 23 °C and minimal rectal temperatures below 30 °C, (6) distal enucleation and felt reinforcement for in zone III distal anastomosis using four branched graft, (7) early re-warming after distal anastomosis with ACP flow adjustment while monitoring brain oxygenation by near-infrared spectroscopy (NIRS) and (8) second anastomosis is proximal and last one is arch vessel reconstruction, (9) maintaining strict fluid balance below 1000 ml by the extracorporeal ultrafiltration method (ECUM) during cardiopulmonary bypass (CPB), with the expectation of more rapid pulmonary functional recovery.
