요오드 과민반응이 있는 인조혈관 동정맥루 폐쇄 환자에서 Gadolinium 조영제를 사용한 성공적인 혈관확장술

Percutaneous transluminal angioplasty (PTA) using iodine contrast dye has been used as the definitive method of choice for treating hemodialysis vascular access dysfunction. Occasionally, iodine material can not be used in the hemodialysis patients with a history of severe hypersensitivity reactions or the predialysis patients with premature access awaiting hemodialysis treatment. Gadolinium chelates have been reported as an alternative contrast agent for angiography or angioplasty in such patients. Here we report a case of successful angioplasty of arteriovenous graft obstruction using gadolinium chelate (gadopentetate dimeglumine) in a patient with repetitive iodine hypersensitivity reactions.
