Major venous anomalies and abdominal aortic surgery

Patients with an infrarenal venous anomaly are relatively rare, but are most likely to suffer bleeding from an injury during abdominal aortic surgery. During the last five years, we have performed nine abdominal aortic surgeries with major venous anomalies. There was no severe haemorrhage and actually, after 3-53 months (median 28 months) all the patients have done well. Preoperative assessment and intraoperative awareness are important to prevent unexpected injuries and subsequent excessive bleeding. If the venous anomalies are recognized and treated correctly, serious injuries can be prevented and the outcome should not be affected. In elderly patients, with severe comorbidities or inflammatory aneurysms, an endoprosthesis is preferred.
