- W4248935900 abstract "This article describes the treatment of 56 early and late vascular complications of native arteriovenous fistula (AVF) in patients with end-stage renal disease, between January 1987 and January 1999. Twenty-six were arteriovenous aneurysms and 2 pseudoaneurysms; 25 were thromboses. We also observed two cases of periarteritis associated with systemic lupus erythematosus (SLE) and one complex iatrogenic lesion caused by an attempt at percutaneous restoration of potency. We applied microsurgical principles, instruments, and techniques. It was possible to restore a vascular access at the original site, using the same vessels in 45 cases (80.4%). In 10.7% of cases, we were able to rescue the original AVF by microsurgical revision. A new vascular access had to be created proximally in the same limb or in the contralateral forearm in 11 cases of aneurysms (19.6% of the total, 42% of the aneurysms). After a minimum follow-up of 8 months, a total of four patients had to be reoperated for further complications (7.2%). Our data support the idea that microsurgical treatment of vascular complications of native AVF is highly successful compared with results obtained by conventional surgery and, in a defined subgroup of patients, permits salvage of the fistula. Si descrive il trattamento di 56 complicanze vascolari precoci e tardive di fistole arterovenose in pazienti uremici, fra il gennaio 1987 ed il gennaio 1999: ventisei aneurismi arterovenosi, 2 pseudoaneurismi e 25 trombosi. Abbiamo anche osservato due casi di periarterite associata a LES ed una complessa lesione iatrogena causata durante un tentativo di disostruzione percutanea. Abbiamo applicato i principi, gli strumenti e le tecniche della Microchirurgia. È stato possibile ripristinare un accesso nel sito originario, utilizzando gli stessi vasi, in 45 casi (80.4%). Nel 10.7% dei casi si è potuta recuperare la fistola originaria per mezzo di una revisione microchirurgica. In 11 casi di aneurisma (19.6% del totale, 42% degli aneurismi) è stato creato un nuovo accesso vascolare prossimalmente nello stesso lato o sull'altro avambraccio. Dopo un follow-up minimo di 8 mesi, il 7.2% dei pazienti è stato rioperato per ulteriori complicanze. I nostri dati supportano l'idea che il trattamento microchirurgico delle complicanze vascolari delle fistole arterovenose sia estremamente efficace in confronto ai risultati della chirurgia convenzionale, consentendo in un sottogruppo di pazienti il salvataggio della fistola originaria. © 2000 Wiley-Liss, Inc.
