[Transradial approach for diagnostic angiography].

Seventy five arteriographies were performed via the transradial route using 5F 130cm - long catheter. Prior to puncture the radial artery was evaluated with Allen test. Satisfying quality examinations were obtained for the thoracic aorta, selective carotid arteries examinations, infra renal aorta, pelvic and legs arteries.

[Aneurysm of the persistent sciatic artery].

The authors report a case of persistent sciatic artery presenting with limb ischemia and pulsatile mass in the buttock treated only by femoro tibio peroneal by pass graft since follow up helical CTA at six months showed spontaneous aneurysmal exclusion by thrombosis of the persistent sciatic artery above the aneurysm. Review of the literature confirms the rarity of this anomaly, which is frequently associated with aneurysmal transformation and its specific inherent complications. It is treated by femoro popliteal shunt with endovascular embolization.

[Endovascular embolization of a splenic aneurysm and of a false aneurysm of the splenic artery].

Splenic artery aneurysms, once considered rare entities are now being reported with increasing frequency. Rupture may be the presenting and only symptom and can be fatal. The authors present two cases of splenic aneurysms treated by endovascular embolization.

[Percutaneous treatment of a common iliac aneurysm extending to the hypogastric artery with embolization and a covered endoprosthesis].

A case of iliac aneurysm treated percutaneously by endovascular stent graft (Wallgraft - Boston) and transcatheter embolization of internal iliac artery in order to prevent retrograde filling of the aneurysm from the patent hypogastric artery is presented. The initial radiographic evaluation included arteriography, and 2D and 3D spiral CT angiograms. This enabled analysis of the extent of mural thrombus, flow direction, as well as selection of stent graft and coil size.

[Throbbing buttocks syndrome].

The authors define the "throbbing buttocks syndrome" which can in fact correspond to different pathological entities: aneurysm of the persistent sciatic artery and/or congenital or traumatic arteriovenous fistula of the hypogastric and gluteal vessels. Seven cases are reported: 1 case of aneurysm of the persistent sciatic artery complicated by truncal embolism and fissuring which was treated successfully by occlusive endoaneurysmorrhaphy; and 6 cases of arteriovenous fistulas (1 traumatic and 5 congenital). In all cases of arteriovenous fistula the technique used involved initial embolization which was complicated by anterior ligature of the hypogastric artery and then by excision of the malformation which was extremely hemorrhagic in some cases.

[Embolization of arteriovenous malformations using compression. Apropos of 11 cases].

External compression of both arterial feeder and venous return of an MAV allows embolization material to be stabilized into the area of the shunts. 11 patients were treated according to this method, either by an external compression method (4 cases) or by tourniquets (4 cases) or by a balloon compressing the vena cava (3 cases). The material of embolization was in all cases Isobutyl-2-Cyano-Acrylate.

[Persistent sciatic artery. Apropos of a case, review of the literature ].

A case is reported of bilateral persisting sciatic arteries: complete on the right side but incomplete on the left, revealed by the onset of a distal embolism on the right side treated by exclusion and a right femoropopliteal shunt operation. The observation of this further case in France led to a review of the literature which demonstrated the rarity of this congenital anomaly, which usually however represents the only vascular axis to the lower limb, and the frequency of aneurysmal transformations with subsequent complications that are best treated by ligature combined with a femoropopliteal shunt.

Arteriovenous fistulae of the internal iliac vessels.

Seven patients with arteriovenous fistulae of the internal iliac artery are reported. Ages varied from 6 to 50 years (mean 32 years). Cutaneous angiomata , leg oedema and pain was present in 4 cases each, bleeding in 2 cases whilst only one was asymptomatic.

[Injuries to abdominal vessels after surgery of disk herniation].

Four cases of major vascular injury after disc surgery have been treated by the authors. In two instances the symptoms were those of an intra peritoneal haemorrhage after injury to the aorta or to the common iliac artery. These two cases were treated by resection-anastomosis of the vessel.

[Peroperative vascular accidents during orthopedic surgery. Apropos of 55 cases].

The functional or vital prognosis may be affected by the rare vascular accidents resulting from orthopedic operations. During a 10 year period (1970-1980), 55 vascular lesions were observed in 40 patients, and were either arterial (40 cases) or venous (15 cases) in type. Vascular injuries in 9 cases were due to spinal operations (cervical, lumbosacral or herniated disc arthrodesis), in 7 cases to shoulder operations (recurrent dislocation, excision of first rib), in 9 cases to hip surgery (prosthesis, plate and screws, fractured acetabulum), and in 15 cases to operations on the lower limbs (osteosynthesis of femur or tibia, meniscus operations, etc.

[Arterial injuries in civilian practice].

The authors report their experience of arterial trauma in civilian life in a series of 227 patients (average age 38.2 years) with 233 arterial lesions, treated between 1977 and 1981. Iatrogenic trauma is responsible for 45 p.
