超声检查在门静脉栓塞病因诊断中的临床价值研究

Clinical Value of Ultrasonography in the Etiological Diagnosis of Portal Vein Thrombosis

目的对门静脉栓塞病变原因进行调查,同时对门静脉栓塞的超声表现进行研究。方法选取我院2013年7月至2014年8月50例门静脉栓塞患者,患者入院后均进行超声检查,对患者的超声表现进行研究,了解疾病的病因、性质以及发生部位;同时收集患者既往史调查患者发病原因。结果对栓子内血流信号进行检查发现有5例栓子内部发现血流信号。对此5例患者血管内血流状态进行探测后发现,所有患者均显示为高速动脉频谱,确诊为癌栓,但我院50例患者经病理证实有41例为癌栓患者。50例患者中有7例患者门静脉周围存在蜂窝样结构,3例患者门静脉周围出现条纤曲管道结构;上述10例患者的影像资料均显示为网格状红、蓝相间的彩色血流信号,多普勒提示门静脉样血流41例;发生于门静脉和脾静脉的有2例;发生于门静脉和肠系膜上静脉的共2例;发生于所有静脉的共5例。其中原发性肝癌患者36例;其余疾病14例。结论原发性肝癌是本病最常见的病因,超声诊断虽然能够起到一定的鉴别作用,但其对栓子性质敏感度的诊断率较低。

Objective Investigate the cause of portal vein thrombosis lesion, and study the portal vein thrombosis sonographic. Methods Our hospital, between July 2013 and 2014 August, 50 cases of portal vein thrombosis in patients after admission in patients underwent ultrasound examination, ultrasonography of patients studied to understand the etiology of the disease, the nature and occurrence site; at the same time collecting patient medical history investigate causes patients. Results Emboli flow signals within the inspection found that there are five cases emboli found inside blood flow.This state of the patient＇s blood flow after five cases were detected was found that all patients showed a high-speed arterial spectrum diagnosed thrombus, but our hospital 50 patients with pathologically confirmed 41 cases of patients with tumor thrombus.50 patients in the presence of a honeycomb-like structure around seven cases of patients with portal vein, there shall fiber curved tubular structure around the portal vein in three patients; 10 patients above image data are displayed as a grid of red, blue and white color flow signal, tip portal vein doppler blood sample had 41 cases; occurred in the portal vein and splenic vein has 2 cases; occurred in the portal vein and superior mesenteric vein in 2 cases; veins occur in all 5 cases. In which 36 patients with primary liver cancer; the remaining 14 cases of the disease. Conclusion Primary liver cancer is the most common cause of the disease, although ultrasound diagnosis can play a role in the identification, but a lower rate of embolic nature of its diagnostic sensitivity.
