Effect of Obesity on Percutaneous Thrombectomy Outcomes in the Treatment of Lower Limb Deep Vein Thrombosis.

Objective: To evaluate the effect of obesity on percutaneous thrombectomy (PT) results for the management of lower limb deep vein thrombosis (DVT).

Study Design: Retrospective cohort study.

Place And Duration Of Study: Department of Cardiology, Avcilar Hospital, Istanbul, Turkey, between August 2020 and January 2021.

Methodology: Patients who underwent PT for lower limb DVT were included. Patients' demographic characteristics, operative parameters, and postoperative outcomes were recorded in prospective manner. Patients were divided into two groups, as patients with body mass index (BMI) <30 kg/m2 (Group 1) and patients with BMI ≥30 kg/m2 (Group 2). The two groups were compared according to patient demographic properties, intraoperative results, and postoperative outcomes.

Results: Eventually, 62 patients were enrolled into the non-obese group and 30 patients had BMI ≥30 Kg/m2. Comparison of the groups demonstrated that the mean operation time and the mean fluoroscopy time were significantly higher in obese patients (121.5 min vs. 134.5, p = 0.017 and 19.8 min vs. 25.9 min, p = 0.006, respectively). In addition, the mean hospitalisation period and the mean ICU stay were significantly longer in patients with ≥30 kg/m2 (p = 0.025 and p = 0.007). Postoperative visual analog scale (VAS) score in the first hour was significantly higher in obese patients (2.4 vs. 3.0, p = 0.008). The presence of obesity did not have a significant effect on success and complication rates following PT (p = 0.368 and p = 0.646).

Conclusion: Obesity prolonged operation time and fluoroscopy time during PT. Additionally, obesity was associated with significantly longer hospitalisation period, and ICU stay, and higher VAS score in the first hour following PT.
