Abstract

BACKGROUND:
Basilic vein transposition via single long incision is a renowned technique despite its known wound-related complications. Contrary to that, multiple skip incisions technique is thought to have relatively lower wound-related complications. But to the best of our knowledge, these 2 techniques have never been formally compared. Therefore, we conducted this study to compare both.
MATERIAL AND METHODS:
This was a retrospective cohort study. Patients who underwent basilic vein transposition arteriovenous fistula (AVF) from January 2011 till May 2016 at Aga Khan University Hospital, Pakistan were eligible for inclusion in the study. Study population was divided into 2 groups; one group comprising of patients who underwent fistula formation through single long incision and the other group had the procedure carried out via multiple skip incisions. Wound-related complications including wound infection and dehiscence, fistula maturation time, duration of surgery, and primary patency at a follow-up of 12 months were recorded. RESULTS:
Both the groups were comparable regarding baseline variables. Incidence proportion of wound infection, hematoma, and dehiscence was higher in long incision group; however, it was statistically insignificant. Primary patency at 12 months in skip versus long incision group was 73.0% vs. 69.7% (P-value: 0.62). The mean maturation time for fistula was 42.8 ± 9.5 days and 44.3 ± 10.4 days in skip and long incision group, respectively (P-value:0.31). Duration of surgery was comparable in both.
CONCLUSIONS:
Although skip technique does not have significant benefit over long incision technique based on these results, but it is a valid alternative. Randomized control trial is required to better differentiate between these two.
