本研究的目的是用能量多普勒超声评价改良根治性或选择性颈清扫术和微血管皮瓣重建术后颈内静脉的通畅性及其对游离皮瓣存活率的影响。对23例行选择性或改良颈淋巴清扫术及微血管瓣重建术的患者，于术后第1天及术后4个月以上进行能量多普勒超声检查颈内静脉通畅情况。1例患者术后第1天发现部分血栓形成，另22例患者颈内静脉正常通畅。在随访期间，17例(74%)患者发现正常的颈内静脉通畅，而3例(13%)患者发现部分或完全血栓形成。术后第1天，23个游离皮瓣中有22个(96%)可见静脉。随访期内无游离皮瓣丢失。能量多普勒超声是判断颈内静脉通畅的一种有价值的诊断技术，可作为筛查方法或临床怀疑血栓形成时判断颈内静脉通畅的有效方法。晚期颈内静脉血栓形成可能不会因新生血管而影响游离皮瓣存活率。
The objective of this study was to assess patency of the internal jugular vein following modified radical or selective neck dissection and microvascular flap reconstruction by power Doppler ultrasound and its impact on free flap survival. In 23 patients who underwent selective or modified radical neck dissection and microvascular flap reconstruction the patency of the internal jugular vein was examined by power Doppler ultrasound on the first post-operative day and after follow-up of at least four months. On the first post-operative day in one patient partial thrombosis was found, while in the other 22 patients the internal jugular vein was normal patent. During follow-up in 17 (74 per cent) patients a normal patent internal jugular vein was found, while partial and complete thrombosis were found in three (13 per cent) patients each. On the first post-operative day 22 of the 23 (96 per cent) free flap veins were visualized. There was no free flap loss during follow-up. Power Doppler ultrasound is a valuable diagnostic technique for determination of internal jugular vein patency and may be useful as screening method or in case of clinical suspicion of thrombosis to determine internal jugular vein patency. Late internal jugular vein thrombosis may probably not effect free flap survival due to neovascularization.
