    ABSTRACT: To assess the feasibility and safety of early ambulation in patients undergoing transfemoral diagnostic angiography using 4-F catheters or sheaths. In this prospective study approved by the institutional review board, patients undergoing diagnostic angiography were randomized to ambulate 3 or 6 hours after catheter or sheath removal. All patients were assessed for hematoma formation, pseudoaneurysm development, and other groin complications during the in-hospital recovery period and after 30 days. Patient satisfaction and comfort level were also assessed by survey. Of 110 patients (66 men; mean age 64.9 +/- 12.8 years) who participated in this study, 47 were randomized to the 6-hour (6-H) group and 63 to the 3-hour (3-H) group. In the 3-H and 6-H groups, respectively, a 4-F catheter was used in 45 (71%) and 35 (74%) patients and a 4-F sheath in 18 (29%) and 12 (26%). No clinically significant groin complications were encountered in either group. Moderate to severe discomfort was reported in 9 (16%) of the 56 patients responding to the discomfort survey in the 3-H group compared to 10 (26%) of the 38 in the 6-H survey respondents. It is feasible and safe to ambulate patients 3 hours after diagnostic angiography performed with a 4-F catheter with or without a 4-F sheath. Early ambulation of patients after angiography has the additional benefits of increasing patient satisfaction and resource utilization.

    ABSTRACT: To determine long-term outcome in patients 50 years of age or younger treated with iliac artery stent placement. The records of 412 patients who underwent iliac artery stent placement during a 62-month study period were reviewed retrospectively. Forty-two patients younger than age 50 (mean age = 45 y) at the time of stent placement were included in the study population. Presenting symptoms included claudication (47%), rest pain (17%), ulceration/tissue loss (31%), and blue toe syndrome (5%). Anatomic, hemodynamic, and clinical success rates of the stent placement procedure were assessed. Stent patency rates were calculated by life-table methods. Fifty-nine iliac lesions were treated with stents; 62% of patients underwent treatment of a single lesion whereas 38% had multiple lesions treated. Thirty-one percent were treated after a failed angioplasty procedure and 69% were treated with stent placement primarily. After stent placement, 34 patients (82%) experienced symptomatic relief, although eight of these patients (19%) underwent a planned ipsilateral infrainguinal bypass procedure during the same hospitalization. During follow-up, five patients (12%) required a bypass procedure as a result of stent failure and two patients (5%) required below-knee amputation. Seven patients (17%) required endovascular stent revision, with none requiring additional surgery. At 1, 2, and 3 years, the primary patency rates were 86%, 72%, and 65%, and the secondary patency rates were 90%, 88%, and 88%, respectively. Iliac stent placement successfully addresses the presenting symptoms of young patients with peripheral vascular disease and results in patency rates that are similar to those reported in a more general population. With appropriate postprocedural surveillance, restenosis can be addressed in many patients with use of endovascular techniques, limiting the need for surgical revision.
