Relationships of compression degree, type and thrombosis of left common iliac vein in patients with left lower extremity venous insufficiency / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the relationships of compression degree, type and thrombosis of left common iliac vein in patients with left lower extremity venous insufficiency (LEVI). Methods: Totally 258 patients with left LEVI underwent lower extremity CTV. The compression degree, compression type and thrombosis of left common iliac vein were observed, and their relationships were analyzed. Results: Among 258 patients, 84 patients had left iliac vein thrombosis, and the compression degree of left common iliac vein was (54.12±32.73)%. About compression type, there were 5 cases of high-order type, 241 cases of borderline type and 12 cases of low-order type. The difference in compression type between patients with left common iliac vein compression degree <50% and those with compression degree ≥50% was significant (P<0.05). There was significant difference of compression degree between patients with or without left common iliac vein thrombosis (P<0.001). Conclusion: The borderline type is main compression type of left common iliac vein in patients with LEVI, and compression degree ≥50% promotes thrombosis.
