Single loop interrupted suture technique for cerebrovascular anastomosis: Technical note

Abstract

The ideal suturing technique for cerebrovascular anastomosis remains a point of debate. Although simple interrupted sutures are considered to achieve higher patency, they require longer anastomosis time compared with running sutures. The authors describe a novel techniques named single loop interrupted suture to place interrupted sutures for cerebrovascular anastomosis. The single loop interrupted suture technique consists of repeatedly placing, tying and cutting a single loop between anchor stitches. A single loose loop was placed next to the anchor stitch, tied and cut, and then another loop was placed next to the knot. The loops resulted in efficiently placed interrupted sutures. This technique is employed for a range of end-to-side cerebrovascular anastomosis procedures, and is feasible in placing interrupted suture.
