The radial venae comitantes are usually considered as an accessory venous outflow tract in the free radial forearm flap because of their smaller size and thinner structure when compared with those of the cephalic vein. To evaluate the reliability of the deep venous system, a single radial vena comitans anastomosis was performed to serve as the sole venous outflow tract in 94 consecutive radial forearm free flap transfers. The suprafascial dissection technique was used in flap elevation, which allowed preservation of the cephalic vein and the dorsal branch of the radial nerve. In all cases, the external diameter of at least one vena comitans was adequate (< or = 1.5 mm) to perform a smooth microvascular anastomosis; in none of the cases was a venous anastomosis failure detected. Preselected use of a single vena comitans for the venous drainage of radial forearm free flaps was proven to be reliable and was preferred because of the ease of flap dissection and better donor site appearance.
由于与头静脉相比,桡静脉伴行静脉的管径较小且结构较薄,因此在游离桡骨前臂皮瓣中,桡静脉伴行静脉通常被视为一条辅助静脉流出道。为了评估深静脉系统的可靠性,在连续94例桡骨前臂游离皮瓣移植中,进行了单一桡静脉伴行静脉吻合术,作为唯一的静脉流出道。皮瓣掀起采用筋膜上剥离技术,这样可以保留头静脉和桡神经的背支。在所有病例中,至少有一条伴行静脉的外径足够(≤1.5mm),能够顺利进行微血管吻合;所有病例均未检测到静脉吻合失败。预先选择单一伴行静脉用于桡骨前臂游离皮瓣的静脉引流被证明是可靠的,并且由于皮瓣剥离容易且供区外观更好,所以更受青睐。
