RESUMO
Blue toe syndrome is a manifestation of distal embolization associated with significant pain and risk of tissue loss. The recommended treatment options for this problem include endarterectomy or bypass with exclusion of the source of emboli. Although focal arterial stenosis can be effectively treated with angioplasty,it is unclear whether performing angioplasty in a lesion suspected of causing distal embolization might actually worsen the condition or what long-term effects this would have in preventing future embolization. The purpose of this study was to evaluate the treatment and outcome of a series of patients with unilateral blue toe syndrome treated with percutaneous angioplasty and stenting. During a 5-year period, a total of 8 patients were identified with unilateral blue toe syndrome. Ankle/brachial indices (ABIs) were obtained, followed by arteriography. The study group included 4 men and 4 women with an age range of 35 to 83 years. Their atherosclerotic risk factors included smoking (8), hypertension (5), diabetes mellitus (3), and hypercholesterolemia (1). One patient had a history of illicit drug use. The patients were followed up by repeat clinical examinations and vascular laboratory studies. Arteriography typically demonstrated a focal preocclusive lesion with thrombus at the distal end of the lesion. Angioplasty and stent placement was technically successful in all cases. The ABIs increased following angioplasty (before 0.81 +/- 0.05; after 1.02 +/-.05). The symptoms resolved in all 8 patients over the ensuing month, and there were no recurrences with a mean follow-up of 18.5 months (range 4 to 36 months). There was 1 death at 4 months associated with preexisting colon carcinoma. Unilateral arterial to arterial emboli were found in association with focal preocclusive lesions. Despite the presence of thrombus in some of the lesions, these patients were not acutely worse following angioplasty. There was good initial angiographic success in all cases. There was also hemodynamic improvement as shown by the increased ankle/brachial indices. Although long-term follow-up is not available, these intermediate results suggest that angioplasty and stenting should be considered a reasonable alternative to standard operative approaches for patients with blue to syndrome associated with embolization from a focal stenosis.

Between January 1980 and June 1990 we treated 21 patients with invasive carcinoma of the bladder and abdominal aortic aneurysm. Three distinct groups of patients were identified. Group 1 comprised 8 patients who were initially diagnosed with invasive bladder cancer and during cancer staging a concomitant abdominal aortic aneurysm was found. Group 2 consisted of 10 patients previously treated for invasive bladder cancer who had aneurysmal disease at a later date. Group 3 included 3 patients who underwent a previous aneurysm repair and subsequently had invasive carcinoma of the bladder. Total survival was 9 of 21 patients (43%) with a mean of 84 months of followup after initial diagnosis. This finding is comparable to long-term (greater than 5 years) survival in patients with invasive carcinoma of the bladder alone. In fact, none of the 21 patients studied experienced rupture of the aneurysm and/or died of aneurysmal disease. We found that patients with abdominal aortic aneurysm and invasive bladder cancer have a poor overall prognosis. Although aneurysm repair presents technical challenges, mortality is dependent upon the carcinoma and other vascular or medical diseases, and does not bear direct relationship to abdominal aortic aneurysm.
