Popis: Introduction: Accurately assessing the location, degree of stenosis, and size requirements for stenting, as well as delineating the venous anatomy to identify optimal landing zones, are crucial elements for achieving successful outcomes in deep venous stenting procedures. Aim: Is to compare and analyse the sizing of stents used in iliac vein obstruction , specifically between venography and IVUS (intravascular ultrasound) guidance. Materials and Methods: A review of retrospectively collected data at JIVAS between 2016 and 2023[the selected time frame was determined based on the comprehensive availability of data.]conducted on procedural data that were contemporaneously entered into an electronic medical records database for iliac vein stent placements, including attempted cases (N=26), for iliac vein obstruction. The analysis focused on 23 limbs from 23 patients. Out of these, 14 patients underwent stent placement guided by venography, while 9 patients had stent placement guided by intravascular ultrasound (IVUS). Three out of the 26 patients who were to undergo stenting based on Venography were not included since intraoperative IVUS revealed no evidence of compression. Results: The distribution of interventions showed that venography was employed in 61% of cases, while IVUS was used in 39% of cases. Regarding the etiology of the condition, 83% of cases were attributed to NIVL, 13% to NIVL+PTS, and 4.3% to PTS.The Stent length variable had a mean of 92.6 (with a standard deviation of 29.4) and a median of 80.0 [80.0; 110]. The range for Stent length spanned from 40.0 to 150. The median length of the intervention was significantly different between the two groups (p
