The value of three-dimension digital subtraction angiography in diagnosis and treatment of iliac vein compression syndrome / 中华普通外科杂志

ABSTRACT

Objective:To evaluate the application value of three-dimension digital subtraction angiography (3D-DSA) in the diagnosis and treatment of iliac vein compression syndrome (IVCS).Methods:A retrospective analysis was made on 171 patients with a tentative diagnosis of IVCS based on signs, symptoms, and finding of CTV or MRV, and iliac vein angiography. The diagnostic efficacy of MRV, 2D-DSA and 3D-DSA were analyzed. The imaging advantages of 3D-DSA in the diagnosis and treatment of IVCS were evaluated.Results:Ninty-three patients underwent MRV and 3D-DSA simultaneously, 101 patients had 2D-DSA and 3D-DSA simultaneously. 3D-DSA was taken as gold standard, the diagonotic sensitivity, specificity, Youden index of MRV was 75.61%, 72.73% and 0.48 respectively. The sensitivity, specificity, Youden index of 2D-DSA was 90.22%, 100% and 0.90 respectively. There are significant differences in the diagonotic sensitivity between MRV and 3D-DSA, 2D-DSA and 3D-DSA ( P<0.05). There is no significant difference in the diagonotic specificity between MRV and 3D-DSA, 2D-DSA and 3D-DSA ( P=1.000). In this study, we found that 3D-DSA has greater imaging evaluation advantages in preoperative evaluation, intraoperative guidance and immediate postoperative reexamination in the diagnosis and treatment of iliac vein disease. Conclusions:3D-DSA can improve the detection rate of IVCS, and has its advantage in imaging evaluation.
