Aortic stent and renal autotransplantation for the management of renovascular hypertension with Takayasu's arteritis: report of a case.
ABSTRACT Takayasu's arteritis (TA) is a rare inflammatory disease affecting the aorta and its major branches. In patients with TA, middle aortic syndrome with aortic and renal artery involvement causes severe hypertension that does not respond well to medical therapy. Currently, the optimal therapeutic options have not been established, and the reported results of different treatments vary widely. We herein present a case of middle aortic syndrome with renovascular hypertension caused by TA in a 12-year-old male treated by an aortic stent and renal autotransplantation as a two-staged procedure.

ABSTRACT: This study was undertaken to define the long-term effects of renal revascularization on blood pressure, and renal and cardiac function in patients with Takayasu arteritis-induced renal artery stenosis (TARAS). Twenty-seven patients (25 women; mean age, 27 years) with TARAS underwent intervention. Primary, primary assisted, and secondary patency rates were determined, and the late effects on blood pressure, renal and cardiac function, and survival were analyzed. All patients had hypertension (mean blood pressure, 167/99 mm Hg; 2.5 antihypertensive medications per patient). Mean estimated glomerular filtration rate in patients not receiving hemodialysis was 76 mL/min, and in five patients serum creatinine concentration was greater than 1.5 mg/dL. Three patients were hemodialysis-dependent, and two had intractable congestive heart failure. Forty interventions were performed, including 32 aortorenal bypass procedures, two repeat implantations, four nephrectomies, and two transluminal angioplasty procedures. Postoperative morbidity was 19%. There were no deaths. During follow-up (mean, 68 months), three graft stenoses, all due to intimal hyperplasia, and three graft occlusions occurred. Two of three graft stenoses were successfully revised. At 1, 3, and 5 years of follow-up, primary patency was 87%, 79%, and 79%, respectively; primary assisted patency was 93%, 89%, 89%, respectively; and secondary patency was 93%, 89%, and 89%, respectively. Intervention resulted in a decrease in blood pressure to a mean of 132/79 mm Hg (P<.0001), and the need for antihypertensive medications was reduced to one per patient (P<.01). Mean glomerular filtration rate increased to 88 mL/min (P<.005), and two patients no longer required hemodialysis. Congestive heart failure resolved in both patients, and did not recur. There were three deaths during follow-up, with 5-year and 10-year actuarial survival of 96% and 80%, respectively. Renal revascularization to treat TARAS is durable, has a salutary effect on blood pressure, and enhances long-term renal and cardiac function. This response establishes renal revascularization as a successful and durable intervention for TARAS, and a benchmark to which other therapies should be compared.Journal of Vascular Surgery 04/2004; 39(4):749-57. · 2.98 Impact Factor

ABSTRACT: Criteria for the classification of Takayasu arteritis were developed by comparing 63 patients who had this disease with 744 control patients with other forms of vasculitis. Six criteria were selected for the traditional format classification: onset at age less than or equal to 40 years, claudication of an extremity, decreased brachial artery pulse, greater than 10 mm Hg difference in systolic blood pressure between arms, a bruit over the subclavian arteries or the aorta, and arteriographic evidence of narrowing or occlusion of the entire aorta, its primary branches, or large arteries in the proximal upper or lower extremities. The presence of 3 or more of these 6 criteria demonstrated a sensitivity of 90.5% and a specificity of 97.8%. A classification tree also was constructed with 5 of these 6 criteria, omitting claudication of an extremity. The classification tree demonstrated a sensitivity of 92.1% and a specificity of 97.0%.Arthritis & Rheumatology 09/1990; 33(8):1129-34. · 7.87 Impact Factor

ABSTRACT: A 13-year-old girl with middle aortic syndrome caused by Takayasu's disease was treated by balloon angioplasty of the right renal artery stenosis and the implantation of 3 stents, 2 in the stenosed thoracic segment and 1 in the abdominal segment of the aorta. Spiral computed tomography one and two years after the stents were inserted showed that the disease had progressed despite treatment with immunosuppressants.Revista Espa de Cardiologia 07/2002; 55(6):682-5. · 3.34 Impact Factor
