Abstract:
Objective: To evaluate the effect of venous anastomosis by using microvascular coupler during repair and reconstruction surgery after recection of tumor in oral and maxillofacial area. Methods: 20 patients with oral and maxillofacial tumor were chosen for repair of the defects via free flap. Microvascular coupler was applied to combine venous system,however,traditional methods were used in arterial anastomosis. Results: The average time of venous anastomosis using microvascular coupler was (5. 75 ± 0. 53) min,none of the cases were suffered from thrombosis after surgery. Vascular nerosis resulted from arterial spasm occured in 1 flap,reaching the flap survival rate of 95％(19 /20). Neck bleeding occurred in 1 case after surgery,the reflux of the anastomosed vein went smoothly when the blood clot was cleared,flap healing was unaffected. In another case,the coupler released during the surgery due to thick blood vessel wall as well as hypertension among the anastomotic edge,the vessels were manually sutured. Conclusion: With the appropriate indications, application of microvascular coupler may shorten the operating time,without affecting the effect of vascular anastomosis. The possibility of coupler loosing should be alarmed when bumped into great anastomotic tension or thick wall of the vein.
