Critical Preoperative Hemoglobin Value to Predict Anemia-Related Complications After Cardiac Surgery.

Objectives: Preoperative anemia is frequent in patients undergoing cardiac surgery and is associated with increased postoperative complications. The purpose of this observational study was to estimate the critical preoperative hemoglobin threshold associated with the occurrence of complications after cardiac surgery.

Design: A retrospective observational cohort study.

Surgery of acute type A dissection: what have we learned during the past 25 years?

Every acute dissection involving the ascending aorta (Stanford type A) must undergo emergency surgical repair. However, the surgical techniques must vary according to the clinical presentation of the patients or the anatomical patterns observed. Furthermore, surgery is generally difficult because of the poor condition of the aortic tissues.

Surgery for acute type A aortic dissection: the Hopital Foch experience (1977-1998).

Background: In 1977, we proposed the use of gelatin-resorcinol-formol (GRF) biological glue during surgery for acute type A aortic dissection.

Methods: From January 1977 to March 1998, 204 patients (146 men and 58 women) aged from 15 to 79 years (mean 54 +/- 11) underwent emergency operation for type A aortic dissection in our institution. One hundred sixty-five patients (84%) were operated on within 48 h after the onset of symptoms.
