超声诊断肿瘤患者PICC置管术后并发血栓的价值

目的探讨超声检查在肿瘤患者PICC置管术后并发血栓诊断中的应用价值。方法对22例肿瘤患者PICC置管术后出现局部症状患者行超声检查，观察导管在血管内位置及走向，血管管径、血流方向及血流状态，是否有血栓形成及形成部位、大小、形态、血流情况及范围。结果20例患者有不同程度的血栓形成，形成血栓的最常见部位是置管穿入静脉处。超声检查可见局部静脉管径增宽，管腔内可见低回声，部分或全部闭塞。血栓出现时间5-37d，平均14d。结论血栓是肿瘤患者PICC置管术后的主要并发症之一，彩超随访可对该并发症及时诊断，以便临床及时处理。

Objective To explore the value of ultrasonography in the diagnosis of the PICC associated thrombosis in patients suffered from cancer. Methods After PICC, 22 cases of patients with cancer with local symptoms received ultrasound examination, the location and direction of catheter in blood vessel, the diameter of blood vessel, the direction and the status of bloodstream, the formation of thrombi and the location, size, pattern, bloodstream and range of thrombi were observed. Results 20 cases of patients suffered from different ranges of thrombosis, the commonest location of thrombosis was the venous puncture position. Local venous widening, low echo in the blood vessel, partial or total obstruction were found with ultrasonography. The time of thrombosis was 5 to 37 days and 14 days in average. Conclusion Thrombosis is one of the major complications in patients with caner after PICC.Color Doppler ultrasound can be used to diagnose the complication in time, so that the clinical treatment in time.
