ABSTRACT

Percutaneous patent foramen ovale (PFO) closure is a treatment for cryptogenic stroke and migraine headache. The goal of this study was to assess long-term outcomes of patients treated with percutaneous PFO closure. Records of patients with percutaneous PFO closure at Emory University Hospital from February 2002 to July 2009 were reviewed. Follow-up telephone questionnaire and chart review assessed recurrent stroke, migraine, and complications. Data was reviewed on 414 consecutive patients. Long-term follow-up was obtained in 207 of patients, and mean follow up was 4.6 ± 2.0 years. Cryptogenic stroke was the primary indication for intervention in 193 (93%) patients. Thirteen (7%) patients had a recurrent neurologic event post closure. In patients with multiple neurological events at baseline, 17% (n = 11) had a recurrent event, compared with 2% (n = 2) of patients with a single neurological event prior to PFO-closure (P < 0.002). Post closure, migraine frequency and severity declined from 4.5 to 1.1 migraine/month (P < 0.01) and 7.2 to 3.6 out of 10 (P < 0.01) in patients with history of migraine (n = 60). Thirty-day mortality was 1% (n = 2). One patient had device erosion 5 years post-procedure requiring emergent surgery. Atrial fibrillation was newly diagnosed in 8 (4%) patients within 6 months. In conclusion, the long-term rate of recurrent stroke after PFO closure is low in patients with a single neurological event at baseline. Serious long-term complications after PFO closure are rare. PFO closure may decrease the frequency and severity of migraine.

ABSTRACT

Copper is an essential cofactor in many enzymatic reactions vital to the normal function of the hematologic, vascular, skeletal, antioxidant, and neurologic systems. Copper deficiency in the United States is believed to be relatively rare but has been described in the setting of zinc supplementation, myelodysplastic syndrome, use of parenteral nutrition and chronic tube feeding, and in various malabsorptive syndromes, including following gastrectomy and gastric bypass surgery. Features of copper deficiency include hematologic abnormalities (anemia, neutropenia, and leukopenia) and myeloneuropathy; the latter is a rarer and often unrecognized complication of copper deficiency. We here describe two patients who presented with severe gait abnormalities and anemia combined with neutropenia several years after roux-en-Y gastric bypass (RYGB) surgery for obesity who were found to be severely copper deficient. Intravenous copper repletion resulted in the rapid correction of hematologic indices; combined intravenous and oral copper supplementation and eventual oral copper supplements alone normalized serum copper levels in each patient, but resulted in only partial resolution of the neurologic deficits. This report serves to alert physicians of the association between RYGB procedures and subsequent copper deficiency in order to avoid diagnostic delays and to improve treatment outcomes.

ABSTRACT

Cardiac nocardiosis is a rare disease that is nearly always associated with cardiac operation. We report the case of a patient with a 10-month history of intermittent fevers after coronary artery bypass operation who presented with progressive shortness of breath and fever. He was found to have a large aortic aneurysm secondary to Nocardia nova infection likely transmitted during his original bypass operation. This is the first reported case of Nocardia aortitis after coronary bypass operation and serves to alert physicians of this rare but serious postoperative complication.
