Abstract
Introduction: Endovascular stenting is the standard of care for the management of symptomatic chronic venous obstruction. The increased radial resistive force and longer lengths of Nitinol stents have led to questions over persistent post-operative back pain. The purpose of this investigation was to assess the incidence and severity of post-operative back pain of Nitinol stents compared to Wallstents.
Methods: A retrospective review of data at the Center for Vascular Medicine was performed. Patient demographics, pre-operative, one week, three-, six,- and 12 month visual analog pain scores (VAS) for back pain, stent type, diameter, length, and vein locations were assessed.
Results: From April 2014 to November 2021, 627 (412 women/215 men) patients were assessed for the presence of post-operative back pain after an initial iliac vein stent placement. Stents utilized were Wallstents (n = 114), Venovo (n = 342), and Abre (n = 171). The most common Nitinol stent diameter and lengths were 14 mm, 16 mm, and 120 mm, respectively (p ≤ .03). The incidence of back pain at one week was 66% (411/627). VAS scores at one week and one, three, and six months post-operatively were the following: Wallstents-2.6 ± 3 (n = 66), 1.7 ± 2.6 (n = 43) 0.7 ± 2 (n = 51), and 0 ± 0 (n = 27); Abre-3.5 ± 3 (n = 130), 3.8 ± 3 (n = 19), 1.2 ± 2.5 (n = 12), and 1 ± 2 (n = 5); and Venovo- 2.5 ± 3 (n = 216), 2.4 ± 3 (n = 70), 0.9 ± 2 (n = 68), and 0.6 ± 1.7 (n = 49). There was no difference in the severity of back pain at any time point (p ≥ .99). The development of back pain was unrelated to stent type, diameter, length, or covered vein territory.
Conclusions: Post-operative back pain was observed in 66% of patients at one week. The average pain score at one week for the entire cohort was three, which declined to less than one at one month. No difference in the severity of back pain between groups was observed at any time point, and the development of back pain is unrelated to stent type, diameter, length, or covered vein territory.
期刊介绍:
The leading scientific journal devoted entirely to venous disease, Phlebology is the official journal of several international societies devoted to the subject. It publishes the results of high quality studies and reviews on any factor that may influence the outcome of patients with venous disease. This journal provides authoritative information about all aspects of diseases of the veins including up to the minute reviews, original articles, and short reports on the latest treatment procedures and patient outcomes to help medical practitioners, allied health professionals and scientists stay up-to-date on developments.
