Patency and Caliber Change of the Internal Jugular Vein in the Oral Cancer Patients Receiving Cancer Ablation, Modified Radical Neck Dissection and Free Flap Reconstruction

根據之前統計報告，口腔癌重建病人，在接受頸部淋巴廓清手術後，發生內頸靜脈血栓的比率並不少見。靜脈的狹窄被認為是其中一個重要因素。因此，在術前和術後評估內頸靜脈管徑的變化是很重要的。從2004年五月到2005年五月，進行了一個前瞻性研究：對於口腔癌病人的內頸靜脈通透性及管徑變化，分別在術前用電腦斷層掃描及術後一天、七天、三個月，用都普勒超音波評估。在二十位病人中，沒有內頸靜脈血栓發生；內頸靜脈的通透率為百分之百。內頸靜脈的術後術前管徑比率平均值，在術後一天、七天、三個月分別是0.706、0.724、0.962。因此，我們認為，內頸靜脈在術後初期會變得狹窄，然後在三個月的期間恢復到接近原來尺寸；然而，發生內頸靜脈血栓的比率並不如之前統計報告那麼常見。

Background The incidence of the internal jugular vein thrombosis (IJVT) after neck dissection had been reported common in reconstruction surgery of oral cavity tumor patients. Development of narrowed but patent vein was regarded as one of the factors leading to thrombus formation after neck dissection; therefore, changes in the caliber of IJV should be assessed before and after operation. Methods From May 2004 to May 2005, we performed a prospective study of 20 patients who received neck dissections that spared IJV and immediate free flap reconstruction for oral cancers. The patency and caliber of the IJV of all patients was evaluated with a CT scan preoperatively and duplex Doppler ultrasound examinations were performed at 1 day, 7days, and 3 months postoperatively. Results No thrombosis of the IJV was noted both in preoperative and postoperative evaluations. All free flap reconstruction was successful. The mean ratio of the post-over the preoperative caliber of the IJVs after 1 day, 7 days and 3 months was 0.706, 0.724, and 0.962, respectively. Conclusions The caliber of the IJV decreased during the early postoperative period; however, it returned to close to normal gradually after 3 months.
