The influence of postoperative radiotherapy (RT) on the patency and blood flow of the internal jugular veins (IJV) after functional neck dissection (FND) was assessed in a prospective study. Doppler ultrasonography of the IJV was performed before and after surgery. Fifty-four FND were evaluated in 29 oncological patients who underwent surgery between September 1994 and February 1997. Twelve IJV received postoperative RT. There were no cases of thrombosis before or after surgery in any case. Blood-flow speed in the right Valsalva maneuver was the only parameter affected in irradiated patients.
在一项前瞻性研究中，评估了术后放疗（RT）对功能性颈清扫术（FND）后颈内静脉（IJV）通畅性和血流的影响。在手术前后对IJV进行多普勒超声检查。对1994年9月至1997年2月间接受手术的29例肿瘤患者的54次FND进行了评估。12条IJV接受了术后放疗。在任何病例中，手术前后均无血栓形成病例。在接受放疗的患者中，右侧瓦尔萨尔瓦动作时的血流速度是唯一受影响的参数。
