Here we describe the clinical manifestations and ultrasound findings of ipsilateral VA in patients with high-grade stenosis of the SCA, and the role of VA ultrasound in percutaneous transluminal angioplasty (PTA) stenting of the SCA. Patients : Twelve patients (male: 10, female: 2; age: 17–86 yr) were selected from among inpatients with SCA stenosis treated in our department between 2009 and 2015. Results : The affected vessel was the left in 8 cases and the right in 4. The causes of stenosis were atherosclerosis in 10 cases, congenital in 1, and arteritis in 1. The symptoms were dizziness, faintness, syncope, diplopia, dysar-thria, rest pain, coldness and arm claudication on effort. The cases were divided into SSS (n=7), SSP (n=2), and SCA stenosis only (n=3). The Doppler flow patterns were classified as normal antegrade (n=3), bunny waveform (n=0), alternating (n=6), reverse (n=2), and not detected (n=1). Ten of the patients underwent PTA stenting and 2 conservative therapy. Conclusions : Alternating and reverse flow patterns in the VA might lead to the surgical indication for PTA-stenting of SCA.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"63 1","pages":"18-22"},"PeriodicalIF":0.1,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88898036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mobile lesions ≥2 mm in diameter were observed for 7 patients (6 men, 1 woman) treated in our hospital between January 2002 and July 2015. Mean age was 67.8 years (range, 52-84 years). Diagnosis was major stroke in 1 patient and transient ischemic attack/minor stroke in 6 patients. Surgical treatment was performed in 6 cases: carotid endarterectomy in 4 and carotid artery stenting in 2. The remaining patient did not undergo surgery because of a marked reduction in size of the mobile lesion after observation for 5 days. Surgical intervention was performed at a mean of 20 days (range, 1-52 days) after onset. None of the 6 operated patients had any complications pre- or postoperatively. We proposed four mechanisms for mobile lesions on imaging, based on pathological findings and responses to antithrombotic therapy: floating plaque entangled with ulcer edge; mobile thrombus adherent to ulcer edge or erosion of the plaque; pulsatile dissected arterial wall; and oscil-lating lodged embolus in the carotid artery. Choosing the operative procedure and timing in accordance with the underlying mechanism is important.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"58 1","pages":"22-27"},"PeriodicalIF":0.1,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78532407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ichihashi","doi":"10.2301/NEUROSONOLOGY.29.13","DOIUrl":"https://doi.org/10.2301/NEUROSONOLOGY.29.13","url":null,"abstract":": Pediatric patients presenting with head masses are not rare. However, it is difficult to make a diagnosis based solely on clinical findings. Although CT or MRI can be used for diagnosis, the former has problems associated with radiation exposure. In addition, pediatric patients must be sedated for examination using these methods. Ultrasonography can be performed easily at the bedside, and using a high-frequency probe, it is possi-ble to obtain high-resolution images that surpass MRI images. Here, we report the usefulness of ultrasonography for the diagnosis of superficial soft-tissue head lesions in two children. Case 1 : A 6-month-old girl was referred to our hospital due to a pulsatile mass in the midline of the occipital re-gion. Ultrasonography showed a compressible, hypoechoic, tubular structure, and its vascular communication between the superior sagittal sinus and extracranial vessel through the cranial defect was detected by the color Doppler method. A diagnosis of sinus pericranii was made. Case 2 : A 7-month-old boy was referred to our hospital due to a swelling in the right temporal region. Scalp he-matoma and skull fracture were confirmed by ultrasonography. The patient was closely observed without treat-ment until the fracture healed. Conclusions : Ultrasonography is useful in the diagnosis of superficial soft-tissue head lesions in children. As ultrasonography can be performed repeatedly and noninvasively, it is useful not only for diagnosis, but also for fol-low-up.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"1 1","pages":"13-17"},"PeriodicalIF":0.1,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79049205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
