[Cockett's syndrome. Treatment by venous envelopment in a ringed prosthesis].

The surgical treatment of Cockett's synechiae is now well established, with only minor variations. Various techniques have been suggested to solve the problem of arterial compression, but none of these is fully satisfactory. The authors favour the use of new externally supported grafts, notably the ringed polytetrafluoroethylene (PTFE) prosthesis, to protect the left iliac vein, these grafts being effective and easy to apply.
