Safety and efficacy of stenting nonthrombotic iliac vein lesions in octogenarians and nonagenarians in an office setting

Objectives Treatment options for venous insufficiency are rapidly evolving in the office setting and include venography, intravascular ultrasound, and venous stenting. Non-thrombotic iliac vein lesions assessment and treatment in an office setting is currently an area of interest. The purpose of this study is to demonstrate the safety and efficacy of evaluating non-thrombotic iliac vein lesion with this office-based procedure in octogenarians and nonagenarians. Methods From January 2012 through December 2013, 300 non-thrombotic iliac vein lesion limbs in 192 patients with venous insufficiency ≥80 years old were evaluated for non-thrombotic iliac vein lesion. Patients were evaluated and treated with venography, intravascular ultrasound, and stent placement for significant lesions demonstrated by greater than 50% diameter or cross-sectional area reduction. Group 1: 168 of these patients were octogenarians; female/male ratio was 1.75:1, bilateral in 89/168 patients (53%), left sided in 131/259 limbs (51%), right sided in 128 limbs (49%), average age 83.5 ± 2.6 years (range 80–89) compared to Group 2: 24 nonagenarians; female/male was 3:1, bilateral in 17/24 patients (70%), left sided in 20/41 limbs (49%), right sided in 21/41 limbs (51%), average age 92.9 ± 2.2 years (range 90–99). Stent related outcomes were evaluated with communication to the patient within 24 h to assess post-procedure pain followed by serial iliocaval ultrasonography. Results Out of the 300 limbs evaluated, in Group 1, 86% of limbs had stents placed compared to 90% in Group 2 and 11% of both groups had two stents placed. Overall improvement in pain, edema, and ulcers was reported in 147 (59%) of octogenarians and 24 (65%) of nonagenarians. There were no surgical site infections, pseudo-aneurysms, arteriovenous fistulas, or femoral artery injuries. No patients required transfusion within three days post-operatively and there were no 30-day mortalities in both sets of patients. Conclusions Our results demonstrate that there is no statistical difference in the outcome of performing venography, intravascular ultrasound, and stent placement in an office-based setting in octogenarians and nonagenarians. Both groups maintained a similar safety profile with low morbidity and mortality. In conclusion, we believe that the treatment of non-thrombotic iliac vein lesion in an office-based setting is safe and efficacious in both groups.
