Reconstructive endovascular treatment procedures in the area of the a. subclavia and its branches

Objective: Principles, methods and results of percutaneous therapy in acute and chronic vascular alterations of the subclavian artery and its branches.

Methods: 17 arteries in 15 patients have been treated. The patients suffered from stenoses (n = 6), occlusions (n = 7), aneurysms, (n = 2) or acute hemorrhage (n = 2). The lesions were located in the subclavian artery (n = 8), the axillary artery (n = 4) or the vertebral artery (n = 5). In all cases the procedures were performed via via a transfemoral approach. Balloon angioplasty was employed in 13 cases, in 6 cases bare stents and in 4 cases grafted stents were implanted. In one case additionally local lysis was performed.

Results: Primary technical success was achieved in all cases. No catheter complications did occur. In 13 Patients complete follow-up examinations could be performed. The life-threatening acute hemorrhages were stopped without recurrent bleeding. The aneurysms could be completely excluded without endoleaks. In 4 Patients of the stenosis-group re-stenosis occurred and following stent-implantation one occlusion after 6 months was observed. 8 patients are without clinical symptoms since the intervention.

Conclusions: Stenotic and occlusive vascular alterations as well as aneurysms and the acute hemorrhage in supraaortic arteries can be effectively and safely treated by endovascular techniques using percutaneous groin access.
