New Office-Based Vascular Interventions

OBJECTIVE: Following contemporary trend, various vascular interventions being performed in the office. We describe our office experience with radiofrequency ablation (RFA) of incompetent perforating veins (IPV) and duplex-guided balloon angioplasties of failing/nonmaturing arterio-venous fistulas (AVF). DUPLEX-GUIDED BALLOON ANGIOPLASTIES OF AVF: Eighteen patients with 20 failing arterio-venous (AV) fistulas underwent office duplex-guided balloon angioplasties. Thirteen procedures (65%) were on non-maturing fistulas and the remaining 7 (35%)--in dialyzed patients. Sheath insertion, wire and balloon passage and inflation were guided by duplex only. RFA OF IPVS: We performed 25 radiofrequency ablations of 49 IPVs. Early follow-up scan confirmed total occlusion of 45 (92%) treated IPVs. Patients gender, CEAP class, perforator diameter or GSV patency did not correlate with current procedure failure. CONCLUSION: Excellent duplex imaging quality and technical advances in endovascular tools allowed us safely perform AVF balloon angioplasties and RFA of IPVs in the office.
