title: Clinical correlation of anatomical location of non-thrombotic iliac vein lesion.
abstract: Objective Treatment of non-thrombotic iliac vein lesions is an active area of research. Intravascular ultrasound allows its localization. We chose intravascular ultrasound to clarify the exact anatomical location of non-thrombotic iliac vein lesions and correlate it with clinical findings. Materials and methods Over seven months, we performed ilio-femoral intravascular ultrasound studies on 217 patients, in 141 women and 76 men. The average age ± standard deviation was 68 ± 14 years. We used intravascular ultrasound intraoperatively to measure the ilio-femoral veins and compared it with adjacent non-stenotic ilio-femoral veins. If more than 50% area or diameter reduction was found, it was treated with appropriate balloon and stent. Results We identified 244 lesions, 124 in left lower extremity and 120 in the right lower extremity. The most common site was the proximal common iliac vein 38.7% (22.5% females and 16.12% males) in left lower extremity and middle external iliac vein 29.16% (18.33% females and 10.83% males) in right lower extremity. The least common site was the distal external iliac vein in 3.2% (all 3.2% females) and the distal external iliac vein 7.5% (5% females and 2.5% males) in right lower extremity. Clinical correlation was noted between laterality and location of the NIVL lesion ( p < 0.0001). Conclusion This analysis gives an insight into understanding the exact anatomical locations of the non-thrombotic iliac vein lesions helping clinicians and researchers guide their treatment and research.
