The first measure performed in the treatment of pseudoaneurysms should be reapplication of a compression bandage, followed, if necessary, by UGCR. After failure of UGCR, spontaneous healing occurs in the majority of patients. Operation can be reserved for progressive and complicated lesions.

Background and Purpose-Embolic events are a major cause for procedure-related strokes after carotid endarterectomy (CEA). Transcranial Doppler sonography can reveal embolic events as microembolic signals (MES) during CEA. MES during declamping and shunting are frequently detected. MES during shunting are rare and known to be correlated with the neurological outcome of the patient. In the present study, we analyzed the occurrence of MES within different stages of CEA and whether MES within those stages were correlated with cerebral ischemia, as detected by diffusion-weighted imaging (DWI), and brain infarction, as detected by contrast-enhanced MRI. Methods-Thirty-three patients were monitored intraoperatively for MES using transcranial Doppler sonography. DWI was performed within 24 hours before and after surgery. Positive postoperative DWI led to reexamination with contrast-enhanced T1-MRI 7 to 10 days after CEA for detection of cerebral infarction. Results-MES were detected in 32 of 33 patients. The highest number of MES was found during shunting and declamping.A significant correlation was found between MES and DWI-lesions during dissection. A significant correlation was found between MES during dissection and shunting, and nonsignificant correlation was found between MES and the occurrence of cerebral infarction. Conclusion-MES

Background This study was undertaken to expand the understanding of ultrasound-guided compression repair (UGCR) of postcatheterization femoral artery injuries.Methods and Results In a series of 62 patients with pseudoaneurysms (n=53) or arteriovenous (AV) fistulas (n=9), UGCR was performed as a nonsurgical method in the treatment of postcatheterization femoral artery injuries. When the communicating channel could be visualized (43 cases), pressure was focused on it; otherwise (10 cases) the extraluminal cavity itself was compressed. In 45 cases, the elimination of flow in the pseudoaneurysm and/or the communicating channel could be achieved only with simultaneous temporary complete occlusion of the femoral artery. UGCR was success-
