[Mechanical vascular clips with an automatic stapler in reconstructive microsurgery. Apropos of 16 clinical cases]

From October 1995 through March 1997, we performed 30 microsurgical reconstructions and achieved microvascular anastomoses in 16 with an automatic stapler (VCS) which allows insertion of titanium clips in the everted vessel walls. The mean age of the patients (15 men, 1 woman) was 42 years. Mean vessel diameter of the donor and recipient sites was 2 mm for the arteries and 3 mm for the veins. Recipient vessels had suffered radiation damage in 3 cases. Micro-anastomoses were performed in 26 cases, with end-to-end sutures in 24 and end-to side sutures in 2. There were 11 arterial procedures including 3 bypasses and 15 venous procedures with 1 bypass. Peroperative thrombosis occurred in 2 cases and were treated by undoing the anastomoses and resuturing manually. There were no early or late postoperative vascular complications. This clinical experience confirms the advantages of this mechanical approach to microanastomotic procedures for small vessels as previously demonstrated in experimental work: a system avoiding transfixation, rapid procedure, reliability.
