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

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• The study investigates the long-term efficacy of gelatin-resorcinol-formol (GRF) biological glue in acute type A aortic dissection surgery.
• GRF glue was first proposed for this procedure in 1977.

Purpose of the Study:

• To evaluate the impact of GRF biological glue on surgical outcomes and long-term results in patients with acute type A aortic dissection.
• To identify risk factors for reoperation and late mortality in this patient cohort.

Main Methods:

• A retrospective analysis of 204 patients undergoing emergency surgery for acute type A aortic dissection between 1977 and 1998.
• Data collected included patient demographics, surgical procedures (aortic valve replacement, arch replacement), and postoperative outcomes (mortality, reoperation rates).

Main Results:

• Hospital mortality was 21%. Reoperation was required in 15.5% of patients, with a 28% mortality rate at reoperation.
• Marfan's syndrome and absence of arch replacement were risk factors for reoperation. Emergency operation and thoracoabdominal replacement were risk factors for death at reoperation.
• Actuarial freedom from reoperation at 15 years was 66.4%. Actuarial late survival at 15 years was 46.3%.

Conclusions:

• GRF biological glue significantly facilitates and enhances the safety of emergency surgery for acute type A aortic dissection.
• The use of GRF glue appears to positively influence late results, although patient-specific factors remain critical for long-term outcomes.
