Abstract:
Objective:To evaluate the technical aspects and examine patency rates of stent placement across the inguinal ligament for managing long-segment iliac venous obstruction.Methods:From Jan 2012 to Jan 2017, a total of 73 patients (42 cases of post-acute deep venous thrombosis(DVT) thrombolysis and 31 of post-thrombotic syndrome (PTS)) with long-segment iliac venous obstruction were treated with interventional surgery. All patients underwent balloon dilatation and placement of at least two stents extending below inguinal ligament.Results:The technical success rate was 100%. No serious perioperative complications occurred. The mean duration of the procedure in the DVT group was shorter than PTS group(35±12) min vs. (62±12) min, P<0.05). The mean number of stents did not differ between the two groups.Mean follow up periods was 28.34 months. Overall cumulative primary, assisted primary, and secondary stent patency rates were 100%, 100%, and 100% at 6 months and 87.7%, 95.9%, and 100% at 12 months and 75.8%, 85.1%, and 96.3% at 24 months, respectively(all P>0.05). Edema and pain alleviated significantly in the two groups. There was no stents compressed or fractured. Conclusions:Stenting across the inguinal ligament for treatment of long-segment iliac venous obstruction is a safe, effective, and feasible method.
