Thrombosis is the most frequent cause of failure in microvascular free-tissue transfer. The large communicating vein of the cubital fossa connects the deep and superficial venous drainage of the radial forearm free flap (RFFF). This vein allows the surgeon to simultaneously drain both systems by means of the large veins of the cubital fossa. We prospectively collected data on the venous anatomy of the cubital fossa in 40 consecutive RFFFs over a 3-year period. We then retrospectively reviewed available data from the 14 cases preceding the cases in the prospective series. At least 78% of our patients had a communicating vein that facilitated dual venous drainage; 87% of our RFFFs were drained by both the superficial and deep venous systems, and 90% of our RFFFs had two or more venous anastomoses. We had no RFFF failures in our series of 54 flaps. We present our venous anatomy findings in this series of forearms as well as the venous anastomoses of our 54 patients. The surgi- cal-flap harvest, including the communicating vein and its use, may provide an advantage in the dependability and quality of venous outflow.
血栓形成是游离组织微血管移植失败的最常见原因。肘窝的大交通静脉连接桡侧前臂游离皮瓣（RFFF）的深静脉和浅静脉引流。这条静脉使外科医生能够通过肘窝的大静脉同时引流这两个系统。我们在3年时间里前瞻性收集了连续40例RFFF患者肘窝静脉解剖的数据。然后我们回顾性分析了前瞻性系列病例之前14例病例的现有数据。至少78%的患者有一条便于双静脉引流的交通静脉；87%的RFFF通过浅静脉和深静脉系统引流，90%的RFFF有两个或更多静脉吻合口。我们的54例皮瓣系列中没有RFFF失败病例。我们展示了该系列前臂的静脉解剖结果以及54例患者的静脉吻合情况。包括交通静脉及其使用的手术皮瓣切取，可能在静脉流出的可靠性和质量方面具有优势。
