UGTI was safe and effective in 94% of patients with postcatheterization pseudoaneurysms. Anticoagulant use did not hinder successful thrombosis. UGTI should be the initial treatment of choice for patients with postcatheterization pseudoaneurysms.

There was a high incidence of restenosis and reocclusion with long-segment SFA disease that required stents to achieve initial success. Despite close surveillance and reintervention, anatomic patency at 1 year was poor. However, clinical benefit was maintained in the majority of patients. The outcome was similar in the claudication population compared with those who had limb-threatening ischemia. Percutaneous revascularization of long-segment SFA disease requiring stents should be reserved for patients with critical limb ischemia for which no reasonable surgical alternative exists.

Venous stasis ulcers (VSU) account for approximately 80-90% of lower extremity ulcerations. Given their prevalence and chronic nature, VSU are thought to impose a significant economic burden on Medicare (the USA's largest health insurance program) and other third party payers. However, comprehensive studies on the costs of VSU treatment are lacking. The objective of this study therefore was to examine comprehensively the direct medical costs of treating patients with a VSU in routine clinical practice. A cohort of 78 patients who presented with a VSU to the Cleveland Clinic Foundation (CCF), a large primary and tertiary referral center, was studied retrospectively. All inpatient and outpatient costs related to VSU treatment that were incurred during the year following VSU presentation or until the ulcer healed, whichever occurred first, were quantified. A total of 71 (91%) patients healed during the study. The average duration of follow-up was 119 days (median: 84 days). The average number of visits per patient was seven (range: 2 to 57). A total of 14 (18%) patients underwent 18 hospitalizations for VSU care. The average total medical cost per patient was $9685 (median: $3036). Home health care, hospitalizations and home dressing changes accounted for 48%, 25% and 21% of total costs, respectively. Total costs were related to duration of active therapy, ulcer size and the presence of at least one comorbidity (p<0.05). VSU are costly to manage, especially when time to healing is prolonged. The present findings reflect an underestimate of VSU costs since indirect costs were not examined. Time absent from work, forced early retirement, loss of functional independence and unquantifiable suffering may be additional factors that contribute to the overall burden of VSU.

Angioplasty and primary stenting of the subclavian and innominate arteries can be performed with relative safety and expectations of satisfactory midterm success. Endovascular repair of common carotid artery lesions can be performed with a high degree of technical success, but should be approached with caution when performed in conjunction with ipsilateral bifurcation endarterectomy.

Renal artery stenosis (RAS) may cause hypertension, azotemia, episodes of flash pulmonary edema and congestive heart failure. Renal artery angioplasty and stenting was performed in 207 patients from 1991 to 1997. Thirty-nine of these patients (19%) underwent renal artery stenting for the control of recurrent episodes of congestive heart failure and flash pulmonary edema. All patients had angiographic evidence of severe (>70%) bilateral RAS (n = 18) or severe RAS to a solitary functioning kidney (n = 21). Sixteen patients (41%) were male and 23 (59%) were female, mean age 69.9 years (range 50-85 years). Of the 18 patients with bilateral RAS, 12 (66.6%) underwent bilateral stenting. Mean blood pressure decreased from 174/85 +/- 32/23 mmHg to 148/72 +/- 24/14 mmHg (p < 0.001). Mean number of blood pressure medications decreased from 3 +/- 1 to 2.5 +/- 1 (p = 0.006). Twenty-eight patients (71.8%) had improvement in blood pressure control. The mean serum creatinine decreased from 3.16 +/- 1.61 to 2.65 +/- 1.87 (p = 0.06). Six of 39 patients (15.4%) used angiotensin converting enzyme (ACE) inhibitors prior to stenting whereas 19 of 39 patients (48.7%) used ACE inhibitors poststenting (p = 0.004). Twenty of 39 patients (51.4%) demonstrated improvement in serum creatinine, 10 of 39 patients (25.6%) had stabilization of serum creatinine and nine of 39 patients (23%) demonstrated worsening. The number of hospitalizations due to congestive heart failure in the year preceding renal artery stenting was 2.4 +/- 1.4 and poststenting was 0.3 +/- 0.7 (p < 0.001). The New York Heart Association Functional Class decreased from 2.9 +/- 0.9 prestenting to 1.6 +/- 0.9 poststenting (p < 0.001). Thirty of 39 patients (77%) had no hospitalizations for congestive heart failure during a mean follow-up period of 21.3 months. Nine patients expired during the course of follow up; eight of the nine patients died within the first year after renal artery stenting. Renal artery stenting decreased the frequency of congestive heart failure, flash pulmonary edema, and the need for hospitalization in most patients. Blood pressure was markedly improved in the majority of patients with improved or stabilized renal function. Evaluation for RAS is important in hypertensive patients who present with recurrent congestive heart failure or flash pulmonary edema.
