Methods: Ultrasonography (US) was used to evaluate 78 patients (151 limbs) with lower limb varices at our hospital. The distances between the tibial nerve and small saphenous vein were measured at 20-mm intervals (20, 40, 60, and 80 mm) distal to the sapheno-popliteal junction (SPJ) in 112 of the limbs. The remaining 39 limbs were excluded because the small saphenous vein did not branch off from a deep part of the vein due to a congenital abnormality. Results: The small saphenous vein and tibial nerve were immediately adjacent in 98/112 limbs at the SPJ (1.0±3.3 mm), in 25/112 limbs 20 mm distal to the SPJ (3.9±3.7 mm), in 4/112 limbs 40 mm distal to the SPJ (7.5±3.8 mm), and in none of the limbs 60 mm and 80 mm distal to the SPJ. Conclusion: We recommend points 20 to 40 mm distal from the SPJ as landmarks for the laser irradiation start position for EVLA of the small saphenous vein, because this is where the tibial nerve stops being adjacent to the small saphenous vein.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"1 1","pages":"38-42"},"PeriodicalIF":0.1,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76872587","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}

We report the case of a patient with an abnormal artery originating from the CICA accompanied by hypoplastic vertebrobasilar arteries (VBA) who developed a brainstem infarction. The patient was a 73-year-old woman. In 2013, carotid ultrasonography showed an abnormal artery (diameter 2.2 mm, time-averaged maximal velocity 34 cm/s, pulsatility index 2.4) originating from the CICA that was located 2 cm distal from the right carotid bifurcation. In December, 2014, she developed paresthesia from the neck to the right ear, numbness of the right arm and leg, and right foot motor weakness. MRI showed an infarction in the rostral pons extending to the left midbrain. The abnormal artery that originated from the right CICA associated with the right primitive trigeminal artery and hypoplastic VBAs were confirmed by MRA. This was a very rare case of an abnormal artery originating from the CICA. It is necessary to keep in mind that the presence of branching arteries cannot always be used in the differential diagnosis between the ECA and CICA in carotid ultrasonography.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"71 1","pages":"58-61"},"PeriodicalIF":0.1,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90506355","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}
