Ruptured abdominal aortic aneurysms: a review of 168 cases.

One hundred and sixty-eight ruptured aortic aneurysms presenting at the Princess Alexandra Hospital in an 11-year period have been reviewed. Surgical treatment still carries a high mortality and a very high postoperative morbidity. The survival rate in the Vascular Unit of this hospital has improved during the period studied and in the last five years has risen to 61%. The operative technique is described in detail, and the operative problems and complications are discussed. It is felt that prompt surgical treatment, and accurate assessment of blood loss with adequate replacement during surgery, combined with attention to early postoperative problems, particularly those of a respiratory nature, are the most important factors in survival.
