Background: Ambulatory management of patients is an alternative to conventional hospitalization. In this study we evaluate the results of a prospective cohort study of patients receiving ambulatory endovascular treatment for peripheral arterial lesions.
Methods: From June 2008 to October 2010, ambulatory management was proposed for endovascular treatment of peripheral arterial lesions. An arterial closure device (Angio-Seal(®); St. Jude Medical) was used. For ambulatory treatment, patients were prohibited from driving a vehicle at discharge, had to be accompanied the first night after the procedure, had to live <1 hour from a medical facility, had to be reachable by telephone the day after the intervention, and had to remain hospitalized in the event of a complication. The principal criterion was morbimortality at 1 month. Secondary criteria were clinical improvement, patency, complications related to the arterial closure, and costs evaluation at 1 month.
Results: Forty-five patients were included and 50 ambulatory procedures were carried out. The patients presented with claudication (92%) or a critical ischemia (8%) of the lower extremities. All procedures were carried out by femoral puncture (retrograde in 94% and anterograde in 6% of the cases). The patients presented with iliac (68%) and femoropopliteal (64%) lesions. Lesions included stenoses (70%), thromboses (16%), and intrastent restenoses (14%). The rate of failure of ambulatory hospitalization was 16% (n = 8) without a serious undesirable event: 2 patients were hospitalized after a surgical conversion for iliac rupture and disinsertion of stent; 3 patients developed a hematoma during the intervention at the point of puncture; and in 3 cases the system of percutaneous closure failed. The mean duration of hospitalization was 1.36 ± 1.33 days. At 1 month, clinical improvement was observed in 97.5% of cases, with a primary patency of 100%. No perioperative rehospitalization or puncture site complications were observed. Ambulatory management made it possible to save 42 days of hospitalization, with associated costs of 10,971€, compared with conventional hospitalization. The additional costs related to use of the Angio-Seal amounted to 7427€.
Conclusion: Ambulatory endovascular treatment of patients presenting with peripheral arterial lesions is reliable and effective and may contribute to savings in healthcare spending.
