Limits artery dissection, avoiding artery

Microsurgery - Adults
Prospective study, 101 adults
consecutive patients operated between
January and October 2005 for First
arteriovenous angioaccess creation.
2 Groups:
- 76 patients (Group A) = non yet dialysed
- 25 patients (Group B) = CVC.

Conclusion
Microsurgery allows for high rate distal
AVF creation in incidents patients ,
adults and chidren, with few early
failures, excellent long-term patency
rates and very few ischemic
complications.
Lipectomy is efficient for
superficialization.
