Abstract

This study compares the acute intraoperative arterial elongation technique with the interposition vein-graft method for the closure of small arterial gaps that cannot be repaired by undermining alone. Ten conditioned female mongrel dogs were divided into two groups: a vein graft interposition group and an acute expansion-elongation group. In ten cases, a 25-mm segment of the superficial femoral artery was excised. The resultant defect, measuring 45 to 60 mm, was repaired by an interpositional graft of a comparable size segment of the superficial femoral vein. In ten other cases, a same-size defect was repaired by a tension-free end-to-end anastomosis, following acute intraoperative arterial elongation. The animals were explored at various intervals. Overall results revealed a 100 percent patency rate with the acute expansion-elongation group vs. 80 percent with the vein-graft interposition group. The versatility, time saving, and ease of technique, plus previous clinical experience, is encouraging enough to recommend this method for the sound repair of small arterial defects in clinical cases.

Abstract

In this study, the 3M microvascular anastomotic system was utilized for the first time to perform an end-to-end anastomosis in a non-vascular tubular structure, which was compared to the conventional microvascular suture method. The bicornuate rat uterus was the preferred structure because of its anatomic similarity to the human fallopian tube. Thirty Sprague-Dawley rats underwent 3M and conventional end-to-end anastomoses of their bicornuate uteri. At different intervals, the animals were explored and biopsies were taken for examination under light microscopy. Overall patency rate with the 3M technique was 68 percent vs. 96 percent with the conventional technique. Complication rates were 40 percent with the 3M device and 12 percent with the conventional method. This study concludes that, if this method is to be used on non-vascular tubular structures, further modifications to the system and additional research are mandatory, in order to recommend this technique for clinical application.

45. Clinical applications of acute intraoperative arterial elongation

Abstract

This study reports four clinical cases in which acute intraoperative, extraluminal, arterial elongation was utilized. This technique was developed to facilitate end-to-end anastomoses across vascular defects traditionally bridged with vein grafts. In the reported cases, arterial defects, ranging from 17 to 25 mm, were closed primarily following the application of this technique. Follow-up, ranging from 3 to 34 months, has demonstrated patency in all cases. The authors believe this technique can be used clinically as a reliable alternative to vein grafting for the reconstruction of certain arterial defects.
