[Popliteal artery thrombosis from an osteochondroma of the upper end of the tibia. Apropos of a case].

A rare case of thrombosis of the popliteal artery due to an exostosis of upper end of tibia is reported. It is rare for exostoses to develop at the upper metaphysial region of the tibia, rare fore vascular complications to develop and particularly rare for these to consist of thromboses. This lesion is a differential diagnosis in young adults with lower limb ischemia. Follow up of these exostoses should be by Doppler, after dynamic arteriography to serve as a reference. Surgical treatment should be adapted to the degree of functional disability and the course of the exostosis or the complications it provokes.

[Crossed iliofemoral bypass].

Crossed shunts between the two femoral axes constitute a useful safeguard in unilateral iliac occlusions when the abdominal approach is contraindicated. Hemodynamic considerations suggest the need for iliac implantation from the donor side. This simple technique does not complicate the operation and provides a more satisfactory result than the interfemoral shunt.

[Popliteal vascular injuries. Prognostic classification].

Despite recent advances in the treatment of vascular injuries, the prognosis of injuries to the popliteal vessels is still poor with an incidence of 10-40 p. 100 of amputations recorded in the literature. Mortality rate is 4 p. 100. The authors have seen 13 cases and have studied seven factors influencing the prognosis - the duration of ischaemia, the general condition of the patient, the type of lesion, the state of the veins, the severity of the ischaemia, the level of the lesion and associated soft tissue injury and wounds. Each of the parameters has been assessed with a grade proportional to its severity. The summation of the grades leads to a division into three degrees of increasing severity and allows an early prognosis to be made. In the most severe degree of the lesion, amputation should be performed immediately. Twenty-one attempts at conservative surgery resulted in success in only four cases, with 17 amputations and four deaths among these.

[Extra-anatomical femoropopliteal shunt].

The construction of an extra-anatomical femoropopliteal shunt resulted in the saving of a lower limb following a gunshot wound to the upper third of the thigh involving vascular lesions and extensive tissue loss. By applying this technique it was possible to obtain revascularization of the limb without the septic risks of reconstruction in situ, with the attendant difficulty of initial skin coverage of the wound.

[Bypass on a single major artery of the leg. Theoretical modalities and results apropos of 100 cases].

Sub-crural bypass operations on a single leg artery were analysed retrospectively with a follow-up period ranging from six months to eight years. The vitality of the limb was threatened in the majority of cases (91/96). Whenever possible (79/96) the internal saphenous vein was used as a graft, preferably by the in situ technique. Mortality was 6%. Morbidity with the exception of thromboses was 14.5%. Patency by actuarial analysis was 71.6% at 5 years and 65.8% beyond. The majority of thromboses occurred during the first few months and led, in the majority of cases, to amputation. Secondary thromboses were better tolerated. The influence of various parameters was studied: clinical stage, peroperative flowmeter results, material used, technique, associated procedure (sympathectomy), implantation site and permeable vessel.

[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.

[By-pass from sub-clavian to carotid artery. A rescue procedure in the treatment of common carotid artery hemorrhage (author's transl)].

Rupture of a carotid artery in an infected or irradiated environment is a tragic event that frequently causes immediate death. Plain ligature, when possible, for these patients in a state of shock, leads to cerebral ischemia in 65% of cases. This can be prevented, if one operates soon enough by an extra-anatomic by-pass, avoiding the infected or irradiated area, between the subclavian artery and the homolateral carotid artery. (Study of 2 cases). Such a procedure could be used preventively when the risk for the carotid is highest (particularly septic surgery followed by irradiation).

[Destruction of the valve of the great saphenous vein in the technique of femoro-popliteal bypass in situ (author's transl)].

Destruction of the valves of the great saphenous vein is one of the essential steps in femoro-popliteal bypass in situ. The authors suggest the use of bougies with a tip in the form a shell, the base of which is adorned with 4 rounded and smoothed teeth. After destruction of the great saphenous and ligation of the collaterals, arterial filling of the vein after superior anastomosis and the retrograde insertion of strippers may be used the collapse the valves opened by the blood flow. Amongst 40 bypasses performed using this technique, 38 were without problem.
