RESUMO
This report demonstrates the use of a covered stent for the correction of a fistula from a saphenous vein graft to the right ventricle. The use of this stent resulted in complete obliteration of the fistulous tract and restoration of flow into the sequential limb of the graft.

Thirty patients were treated with percutaneous coronary intervention (PCI) using a 5 Fr guiding catheter. A recently developed, mechanically advantaged hand injector was used to deliver contrast and achieved excellent visualization through the 5 Fr system. Stent sizes ranged from 2.25 to 4.00 mm in diameter and from 8 to 24 mm in length. All primary lesions were successfully treated. The average contrast use was 70 cc per case. There were no major complications and only one minor femoral hematoma. In selected patients, a balloon angioplasty and stent placement can be performed safely and successfully with 5 Fr guiding catheters using currently available products. This technique creates a smaller arterial puncture site, which may obviate the need for a closure device and allow early and safe ambulation. With 5 Fr systems, it appears that contrast usage is reduced, thereby potentially decreasing cost and morbidity. Cathet. Cardiovasc. Intervent. 51:352-357, 2000.

We present the first case of Hantavirus pulmonary syndrome in the Dallas/Fort Worth area. The patient was a 50-year-old previously healthy white man, who had adult respiratory distress syndrome (ARDS) and hypotensive shock after 1 week of nonspecific "viral" symptoms. Despite supportive care, the patient died within several hours of presentation. This case illustrates several of the classic hallmarks of hantavirus infection such as hemoconcentration, thrombocytopenia, ARDS, and shock.

We report a case of brucellosis in a young Mexican man who had weight loss, fever, and nausea. Physical examination revealed hepatosplenomegaly, and examination of the blood showed pancytopenia. This case illustrates the need for a high index of suspicion when patients living in the southern United States have these symptoms.
