OBJECTIVE Left atrium (LA) and left atrial pulmonary venous anatomy have clinical importance for atrial fibrillation (AF) and cardiac tumor surgery. A detailed anatomic knowledge of these structures may faciliate clinical evaluations. The aim of this study was to assess LA size and to demonstrate other anatomic features of LA with pulmonary vein openings in normal population. METHODS This des...

PURPOSE To evaluate and model the risk of in vivo thrombosis in each hepatic vessel type during hepatic microwave ablation as a function of vessel diameter, velocity, and vessel-antenna spacing. MATERIALS AND METHODS A single microwave ablation antenna was inserted into a single porcine lobe (n = 15 total) adjacent to a hepatic artery, hepatic vein, or portal vein branch. Conventional ultraso...

BACKGROUND Recipient vessel selection in head and neck reconstruction using free flap transfers has to be standardized. However, the recipient vessel selection based on the type of neck dissection has yet to be investigated. We describe the relationship between the type of neck dissection and recipient vessel. METHODS Records of 107 consecutive patients who had undergone head and neck reconst...

Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of Jurassic age. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5 ± 2 Ma. Four trends of faults...

In consideration shunts: communication type aneurysm were defined. Additional imaging modalities utilized.Results: 11 patients included study. ages ranged from 0 158 months. T...

PURPOSE As laser speckle flowgraphy can measure blood flow distribution in the ocular fundus, the authors analyzed the relationship between retinal blood flow and aqueous vascular endothelial growth factor (VEGF) concentration in central retinal vein occlusion. METHODS This prospective observational study examined 45 eyes of 45 patients with central retinal vein occlusion before treatment. Bl...

background: deep vein thrombosis (dvt) can be an ethnicity related disease and an important health issue for health-care systems. thus, domestic recognition of risk factors and disease characteristics seem to be inevitable. this study was designed to evaluate the epidemiology, basic characteristics, and risk factors in patients with dvt. materials and methods: in this descriptive cross-sectiona...

backgrounds: there are controversies among surgeons about prophylaxis of deep vein thrombosis (dvt) in laparoscopic cholecystectomy. the aim of this study was the assessment of patients’ condition after laparoscopic cholecystectomy without any prophylactic measure. methods: 100 cases of laparoscopic cholecystectomy without dvt prophylaxis were followed by duplex scanning in the first postoperat...
