Objectives
Paucity of data assessing the safety of iliac vein stenting in an office based setting lead us to analyze our experience with 447 patients.
Methods
447 patients were treated at our office based surgery center. There were 646 limbs over a period of 18 months. Data was collected for Group 1 (less than 80 years of age) had 336 patients and 490 limbs, group 2 (octogenarians) had 94 patients and 132 limbs, and group 3(nonagenarians) had 17 patients and 24 limbs. All patients underwent femoral, iliac and vena cava venograms and intravascular ultrasound (IVUS) assessment. These groups were compared for medical comorbidities, procedure time, CEAP classification, ASA, perioperative local and systemic complications as well as transfer to hospital within 72 hours. Local anesthesia with mild anesthesia was given to all patients. All femoral vein punctures were performed under ultrasound guidance.

Perioperative Local Complications6/4902/1320/24

Out of 646 limbs treated 9 developed complications (Group 1;6, Group2;2, and Group 3;1). Complications included in 1 hematoma formation and 8 deep DVTs. There were no surgical site infections, pseudo-aneurysms, arteriovenous fistulas or femoral artery injuries. No patient required post-operative transfusion and there were no 30-day mortalities.
Conclusions
These data suggests that octogenarians and nonagenarians can safely undergo iliac vein stenting in an accredited and licensed office based surgery center(AAAASF accredited, NYS licensed).
