[Differential diagnosis of venous aneurysm of femoral hernia].

Eight hundred and twelve patients with varicose disease were examined, 18 (2.2%) of them had aneurysms in the region of sapheno-femoral anastomosis. Venous aneurysm was diagnosed before surgery in all 18 patients. All of them underwent surgery with positive result. Diagnosis of aneurysm of great saphena vein in inguinal region is not difficult in most cases. Difficulties usually occur in patients with overweight. In 5 patients with obesity aneurysm was initially diagnosed as femoral hernia. Duplex scanning is the best non-invasive method of diagnosis of venous aneurysm in obese patients.
