Aneurismas das Artérias Viscerais: Alternativa Terapêutica

The authors report two cases in which stent grafts were used to treat visceral artery aneurysms. Case number 1 was a 42-year old woman with a history of renal colic who was found to have a right renal artery aneurysm. Two 6-mm x 20-mm Wallgraft endoprosthesis (Boston Scientific, Watertown, Mass) were placed across the aneurysm neck. Case number 2 was a 72 year-old woman with a past medical history significant for hepatic angioma and hypothyroidism. She was found to have a superior mesenteric artery aneurysm that was treated with a 6-mm x 17-mm Jostent stent graft (Jomed, GmbH, Ra). In both cases the aneurysm was completely excluded and distal end-organ flow preserved. Stent graft placement is a safe and effective treatment for visceral artery aneurysms. If this approach proves durable and reproducible, it can become the method of choice for the management of visceral artery aneurysms in selected patients.

Sulfite Oxidase Deficiency – An Unusual Late and Mild Presentation

Introduction: Sulfite oxidase deficiency (SOD) is an autosomal recessive inherited disease usually presenting in the neonatal period with severe neurological symptoms including seizures, often refractory to anticonvulsant therapy, and a rapidly progressive encephalopathy resembling neonatal hypoxic ischemia, with premature death. Most patients develop dislocated ocular lenses. Later or milder presentations of SOD are being reported with increasing frequency. These presentations include neurological regression with loss of previously acquired milestones or movement disorders. Case report: We report a four years old girl presenting with intermittent ataxia and uncoordinated limb movements. A similar episode of ataxia had occurred previously, one year before, with complete neurologic recovery and normal developmental milestones. Bilateral lens dislocation had been recently diagnosed. Cranial MRI demonstrated bilateral globus pallidus enhancement. Low homocysteine was found in plasma and SulfitestR was positive. Further investigations led to confirmation of isolated sulfite oxidase deficiency with no enzyme activity detected on skin fibroblasts culture. Discussion: This case illustrates the clinical variability of SOD and it is not only atypical but also seems to be the mildest form described so far. The association of ectopia lentis with a movement disorder, even without psychomotor regression, should prompt us to look for this diagnosis.
