[Transradial approach for diagnostic angiography]. / Artériographie diagnostique par voie transradiale.

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. The major advantages obtained for the technique were the very low rate complication and technical failure. Transradial route for arteriography is a reasonable alternative approach to transfemoral or brachial arteriography for out patient management (peripheral angiography) in case in which transfemoral route is not feasible but also with patients with important haemorragic-risks.

[Aneurysm of the persistent sciatic artery]. / Anévrisme de l'artère sciatique persistante.

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]. / Traitement d'un anévrisme et d'un faux anévrisme spléniques par embolisation artérielle percutanée.

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. The initial imaging work-up included sonography, angiography and helical computed tomography with multiplanar and 3D reformations. This enabled comprehensive evaluation of the aneurysms, including their configuration, essential for coil selection. Embolization was uneventful. Post-embolization angiograms confirmed exclusion of the aneurysms. Follow-up CT at 9 months showed complete thrombosis of the aneurysms and no evidence of pancreatic or splenic complication. Endovascular management for definitive treatment of splenic aneurysms is technically possible and should be considered.

[Percutaneous treatment of a common iliac aneurysm extending to the hypogastric artery with embolization and a covered endoprosthesis]. / Traitement percutané d'un anévrisme iliaque primitif étendu à l'artère hypogastrique par embolisation et endoprothèse couverte.

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. The procedure of embolization and implantation was technically uneventful. Post procedure 3D CT and arteriography demonstrated exclusion of the aneurysm, and return to a normal flow pattern. Follow-up at 6 and 12 months confirmed the stability of the results. Percutaneous treatment of common iliac artery aneurysms involving the hypogastric artery can be performed easily, especially in elderly patients. 3D CT is essential in assessing the endo and extra luminal characteristics of the aneurysm to insure optimal results and to detect complications.

[Percutaneous treatment of a superficial femoral artery aneurysm using an intravascular stent-prosthesis]. / Traitement percutané d'un anévrisme de l'artère fémorale superficielle par endoprothèse couverte.

One case of superficial femoral aneurysm treated percutaneously by endovascular stent graft (Passager Boston) is reported. The initial radiographic evaluation included arteriography and color doppler sonography which enable analysis of the flow path, the extent of the wall thrombus, the choice of stended graft size. The procedure of implantation was technically trouble free. The post-procedure 3D CT and arteriography demonstrated occlusion of the aneurysm and resaturation of normal flow path. The six and twelve month check confirmed the stability of the results locally and the integrity of run off vessels. In weakened and specially elderly patient percutaneous treatment of superficial femoral artery aneurysm can be carried out easily. The contribution of 3D CT is essential in follow up to ensure an optimal result and to detect any complication.

[Adventicial cyst of the popliteal artery]. / Kyste adventiciel de l'artère poplitée.

In a 42-year-old man with intermittent calf claudication, cystic adventitial disease of the popliteal artery was demonstrated by 3D CT. Cystic mass was seen to be compressing the arterial lumen. The diagnosis of cystic adventitial was confirmed by surgery. Compared with color doppler sonography, MR Imaging, 3D CT provides additional useful anatomic information concerning disease of the popliteal artery, usually gained only with sonography or arteriography.

-How to obtain the best results using digitalization-. / Comment obtenir le meilleur résultat de la numérisation.

The main characteristics and the relative interest of the different modalities of medical imaging digitalization are presented as well as their most appropriate clinical indications.

[Percutaneous treatment of iliac aneurysms with endovascular stented grafts]. / Traitement percutané d'anévrismes iliaques par endoprothèse couverte.

Two cases of iliac aneurysms treated percutaneously by endovascular stented graft are reported. The initial radiographic evaluation included arteriography and computed tomography with helical acquisition and three dimensional reconstruction. This enabled analysis of the flow path, the extent of the wall thrombus, the choice of stent graft's size. The procedure of implantation was technically trouble free. The post-procedure arteriography and 3D CT demonstrated occlusion of the aneurysm and restauration of a normal flow path. The three, six and twelve month check-ups confirm the good results. In weakened patients or those not requiring aorto-iliac surgery, percutaneous treatment of iliac aneurysm can be carried out easily. The contribution of 3D CT is essential in assessing the endo- and extra-luminal characteristics of aneurysm for indicating the percutaneous route and selecting size of the stented graft.

[Treatment of Cockett syndrome by percutaneous insertion of a vascular endoprosthesis (Gianturco)]. / Traitement d'un syndrome de Cockett par mise en place percutanée d'une endoprothèse vasculaire (Gianturco).

The authors report the use of endovascular stents in the treatment of one Cockett's syndrome. The compression above left iliac vein ranged on 5 cm. The number of stents placed in the patient was as follow: two stents. An ipsilateral femoral approach was used. The stents were placed immediately after dilatation.
