To evaluate hydraulic thrombectomy using a saline-jet aspiration thrombectomy catheter in the treatment of venous thrombosis.
Ten patients underwent 12 hydraulic thrombectomy procedures using 2.7 or 4.0 mm catheters. The site of the thrombus was either central, peripheral or in portal veins. The age of the thrombi was between 2 and 60 days (mean 19.7 days). The efficacy of hydraulic thrombectomy was evaluated based on the aspirated thrombus ratio (ATR), i.e. the volume of the thrombus aspirated divided by the volume of the thrombus before thrombectomy. ATR was estimated by comparing the angiograms of the lesion before and after thrombectomy.
Soft thrombi were usually rapidly removed. ATR was >2/3 in 3, 2/3-1/3 in 2, 1/3-0 in 4, and 0 in 1 patient. The activation time of the injector was 23-224 s (mean 102 s) and the volume of aspirated blood was 30-680 ml (mean 250 ml). Compensatory infusion of saline was performed for blood loss, and 400 ml of packed red blood cells was transfused in 1 patient. No complications of the hydraulic thrombectomy were observed. Thrombolysis or additional treatment were performed in 9 patients.
Hydraulic thrombectomy using this catheter can contribute to the treatment of venous thrombosis.
评估使用盐水喷射抽吸血栓切除术导管进行水力血栓切除术治疗静脉血栓形成的效果。
10例患者使用2.7或4.0毫米导管进行了12次水力血栓切除术。血栓部位为中心静脉、外周静脉或门静脉。血栓形成时间为2至60天（平均19.7天）。基于抽吸血栓比例（ATR）评估水力血栓切除术的疗效，即抽吸的血栓体积除以血栓切除术前血栓的体积。通过比较血栓切除术前和术后病变的血管造影来估计ATR。
软性血栓通常能迅速清除。3例患者的ATR>2/3，2例患者的ATR为2/3 - 1/3，4例患者的ATR为1/3 - 0，1例患者的ATR为0。注射器的启动时间为23 - 224秒（平均102秒），抽吸的血量为30 - 680毫升（平均250毫升）。针对失血进行了生理盐水补充输注，1例患者输注了400毫升浓缩红细胞。未观察到水力血栓切除术的并发症。9例患者进行了溶栓或其他治疗。
使用该导管进行水力血栓切除术有助于静脉血栓形成的治疗。
