Objective: The aim of this retrospective study was to evaluate the possibility to predict postoperative graft patency in coronary surgery by means of intraoperative transit-time flow measurement.
Methods: Of 3567 patients submitted to isolated myocardial revascularization from June 1997 through June 2003, 157 (4.4%) underwent both intraoperative transit-time flow measurement and angiography at follow-up.
Background: In a previous study, we demonstrated that patients with multivessel disease benefit during the first postoperative month from elimination of cardiopulmonary bypass (CPB). We evaluated the midterm results of the same patients excluding the first postoperative month from the analysis.
Methods: From May 1997 to November 2000, 1,802 patients with multivessel disease survived the first postoperative month; 906 were operated on without (group A) and 896 with (group B) CPB.
Background: The impact of aortic manipulation on incidence of cerebrovascular accidents (CVAs) was evaluated in patients who underwent myocardial revascularization.
Methods: From January 1988 to December 2000, 4,875 patients had coronary operations; 33 who survived less than 24 hours and 19 who had aortic cannulation without cross-clamping were excluded. According to the degree of aortic manipulation, patients were divided into two groups: group A, aortic cannulation, cross-clamping, with (A1, n = 597) or without (A2, n = 2,233) side-clamping, and group B, with (B1, n = 460) or without (B2, n = 1,533) side-clamping.
