Usefulness of continuous suture using short-thread double-armed micro-suture for cerebral vascular anastomosis.

BACKGROUND

When microvascular anastomosis is performed in a deep, narrow operating field, securing space to throw knots is difficult. To simplify the procedure and avoid obstruction of the anastomosis, we use a continuous suturing with short-thread double-armed micro-suture.

METHODS

Sixty-four patients (38 cerebral revasculazation, 16 moyamoya disease, and 10 aneurysm surgery) undergoing microvaucular anastomosis were included. During anastomosis, a continuous suture was placed with short-thread double-armed micro-suture.

RESULTS

During 64 microanastomosis procedures, 64 consecutive continuous sutures were performed with 1-year follow up. All patients showed patency of anastomosis with long-term follow up.

CONCLUSIONS

This technique is especially useful for anastomosis in a deep, narrow surgical field, such as in superior cerebellar artery anastomosis.
