To assess the clinical utility of iliac vein stent placement for patients with chronic limb edema or pelvic congestion presenting with nonocclusive May–Thurner physiology.

Materials and Methods

All patients (N = 45) undergoing stent placement for May–Thurner syndrome (MTS) without an associated acute thrombotic event between 2007 and 2014 were retrospectively reviewed; 11 were excluded for poor follow-up. A total of 34 patients (28 female) were studied (mean age, 44 y; range, 19–80 y). Average follow-up time was 649 days (median, 488 d; range, 8–2,499 d).

Results

The technical success rate was 100% (34 of 34). No major and two minor (5%) complications occurred, and 68% of patients (23 of 34) had clinical success with relief of presenting symptoms on follow-up visits. Technical parameters including stent size and number, stent type, concurrent angioplasty, access site, and resolution of collateral iliolumbar vessels were not found to be statistically related to clinical success (P > .05). Similarly, no significant relation to clinical success was seen for clinical factors such as the type of symptoms, presence of chronic deep vein thrombosis (DVT), or concurrent coagulopathy (P > .05). Female sex was found to correlate with clinical success (82% vs 18%; P = .04).

Conclusions

Iliac stent placement in patients presenting with chronic limb or pelvic symptoms from MTS without acute DVT is associated with clinical success in the majority of patients.
