Prosthetic graft occlusion and options of reoperative modality / 中国普通外科杂志

ABSTRACT

ObjectivesTo analyse the causes of occlusion of prosthetic grafts and to explore the appropriate modality of reoperation.MethodThe clinical data of 47 patients with occlusive prosthetic grafts were analyzed retrospectively. The procedure of treatment for patients with different causes of occlusive graft included thrombectomy alone in 9 cases, thrombectomy and anastomotic plasty in 16 cases, new bypass using prosthetic graft and saphenous autograft in 22 cases. ResultsThe reoccurrence of graft occlusion in patients undergoing thrombectomy alone or thrombectomy and anastomotic plasty was 67% and 56% respectively, which was siginificantly higher than that of 9% in patients treated by a new arterial bypass with prosthetic grafts and saphenous autografts. ConclusionsThe result of new bypass for occlusive prosthetic graft is superior to thrombectomy alone or thrombectomy and anatomotic plasty.
