[Cockett's synechiae. Report on 31 cases (author's transl)]

Cockett's syndrome may arise from intraluminal adhesions near the distal end of the left common iliac vein, bone or arterial compression, etc. These synechiae are frequently observed, numerous embryological and histological arguments suggesting their congenital origin. A common complication of these synechiae is a left phlebitis, but they do not appear to be a determining factor for the development of thrombosis, and are otherwise usually asymptomatic. When complications do arise, as in the 31 cases reported, surgical treatment should involve early angioplasty in young subjects, or a late Palma-Dale type of shunt in elderly patients and those with a history of a left iliac thrombosis.
