Superficial repositioning of the artery for chronic hemodialysis: indications and prognosis.
Superficial repositioning of the artery (SRA) is a modality of the blood access operation for chronic hemodialysis that has been previously used in cases of cardiac failure. We performed 42 SRAs from 1986 to 1993; thereafter, we retrospectively investigated the operative indications, postoperative complications, and long-term results. Superficial repositioning of the artery was indicated for the lack of an appropriate vein (17 cases; 40%), frequent and early access failure due to arteriovenous fistula or polytetrafluoroethylene grafts (six cases; 14%), venous hypertension (five cases; 12%), and cardiac failure (two cases; 5%). The patency rates of the SRAs were 87% at 3 years and 58% at 4.5 years. There was some difficulty in finding the returning veins in five of 28 functioning SRAs (18%). The SRA is thus considered to be a secondary-selected blood access operation; however, it also may be used as an efficient blood access for an extended period of time without any serious complications.
