[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.

[Reconstruction of the lumbosacral plexus of an embryo at stage 23 (25mm) and an embryo at stage 16 (7,5mm)].

Two embryos, one at stage 23 and another at stage 16, are reconstructed in view of studying the evolution of the lumbosacral plexus. At stage 16, the sacral plexus begins its development with anastomosis of L5, S1 and S2 roots, while the pelvic member is scarcely sketched. At stage 23, the evolution is complete, the pelvis is entirely constitued and the femoral, sciatic and obturator nerves of adult type. The coccygian plexus is in process of construction.

[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).

[Contribution of computed tomography to the exploration of aortic aneurysms (author's transl)].

A technique for exploring aortic aneurysms is described, and the results analysed in 50 cases (11 thoracic, 32 abdominal, 3 multiple, and 4 with both thoracic and abdominal aneurysms). The diagnostic value of this method appears evident for aneurysms in the thorax, and it can reduce the need for conventional radiological examinations. Results of examination of abdominal aneurysms were compared with those of ultrasonography and angiography. Angiography was more effective for studying collateral lesions, while ultrasonography is still a reliable, non-aggressive, low cost investigational procedure. Computed tomography, however, represents the most polyvalent, non-aggressive technique for evaluating the size of the aneurysm, its thrombotic components, and its extension to neighbouring organs.

The aesthetic hand prosthesis.

The high-quality aesthetic prosthesis can be equally helpful to those with acquired amputation and to those whose loss is due to agenesis. Restoring near-normal appearance improves patients' function in a global sense, enabling them to better utilize what they have in the complex socioeconomic environment of today's mobile society. The aesthetic prosthesis often also gives some prehensile assistance, providing an opposition part for remaining digits or thumb. The needs of each patient must be carefully considered, and the prosthesis must conform to the high standards of quality outlined. Its use is primarily for the unilateral amputee who is making a good adjustment to the loss with realistic expectations.

[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.

[Radio-anatomy of anastomoses between the deep femoral artery and the femoro-popliteal axis].

The anastomoses between the deep femoral artery and the femoro-popliteal arterial axes are clearly visible in angiographic studies when there is an obstruction of the main arterial axis. These anastomoses which allow blood to flow into the distal arteries occur especially in the femoral perforating arteries (ramus perforans arteriae femoralis) in the lateral circumflex femoral artery (arteria circumflexa femoris lateralis) and in the medial circumflex femoral arteries (arteriae circumflexae femoris medialis).

[Ischio-popliteal artery trunk, persistence of the axial artery].

The authors studied two cases of persistent axial artery of the lower limb, a classic but exceptional variation (42 cases in the literature). It is well explained by embryology and is a recapitulation of anatomy in the animal series. By the systematic study of the literature, we can isolate four distinct types: Type I: Complete axial artery, normal femoral artery. Type II: Id., but incomplete femoral artery, with two subdivisions: II a: Femoral artery is present but incomplete. II b: Femoral artery is absent. Type III: Axial artery only in the proximal zone. Type IV: Axial artery only in the distal zone. In these two last types, the femoral artery is complete. The I, III and IV types correspond to organogenetic perturbation at the stage 21 of Streeter. The type II implies a more early disturbance, prior to stage 18.
