彩色多普勒超声对围手术期盆腔肿瘤患者下肢静脉血流评估的意义

The significance of color Doppler flow image in the assessment of lower limb venous blood flow of perioperative patients with pelvic tumor

目的：应用彩色多普勒超声（CDFI）评估围手术期盆腔肿瘤患者下肢深静脉血流状况.方法：对35例伴有下肢肿胀、疼痛等症状的围手术期盆腔肿瘤患者行CDFI检查,确诊有无下肢深静脉血栓（DVT）形成,并测量股静脉的管径和血流速度.术后3～10d复查.结果：11例术前伴发DVT;23例术前未发生DVT,与术后相比术前股静脉内径增宽,股静脉血流速度降低,平静呼吸时股静脉平均最大血流速度降低（P＜0.01）.结论：对出现下肢症状的围手术期盆腔肿瘤患者,特别是恶性肿瘤患者应常规行术前CDFI检查,不仅可以及时诊断DVT,还可以提示患者的下肢静脉血流淤滞状况.

Objective ：To explore the characteristics of lower limb deep venous blood flow of perioperative patients with pelvic tumor using color doppler flow image （CDFI）. Methods：Thirty-five perioperative pelvic tumor patients with lower extremity pain and swell were were detected using CDFI. The diameter and velocity of femoral vein in patients without deep vein thrombosis （DVT） were observed,and which was reexamined at 3 to 10 days after operation. Results： DVT in 11 cases and no-DVT in 23 cases were found before operation. Compared with postoperation, the interior diameter of femoral vein widen, the velocity of femoral vein slowed down, and the average maximum velocity of femoral vein during the quiet breathing decreased before operation（ P 〈0. 01 ）. Conclusions： It is important to examine the lower limbs vein of perioperative patients with pelvic tumor using CDFI, especially for the patients with malignancy, which can early diagnose the DVT and know the lower limb deep venous blood flow of patients.
