Risk factors and neurological consequences of syncopes induced by internal carotid artery angioplasty.

Background And Purpose: Syncope and carotid sinus reactions (CSR) occur frequently in patients undergoing carotid angioplasty (CA). We investigated risk factors and the neurological consequences of carotid sinus syncope induced by CA.

Methods: We examined 359 consecutive patients.

Acute subarachnoid hemorrhage associated with platelet storage pool disease and the hemoglobinopathy caused by beta-thalassemia minor.

We describe a case of acute subarachnoid hemorrhage with a complex blood-clotting mechanism and two negative angiographies. The patient was discharged from hospital with a presumptive diagnosis of idiopathic causes, but further analysis of the clinical history from the primary care provider prompted a hematologic analysis, which produced a diagnosis of platelet storage pool disease with alterations during the degranulation and aggregation functions. Electron microscopy revealed no ultrastructural abnormalities of platelet membranes, granules, or organelles.

[Percutaneous occlusion with coils of coronary artery fistulas in adults].

Coronary artery fistulas are one of the most common congenital anomalies of the coronary arteries. Most fistulas are small and of no clinical significance, although larger or multiple fistulas can be symptomatic and produce complications. Early percutaneous occlusion is now always recommended, and surgical closure is restricted to use for multiple or large fistulas.
