Background In preoperative lipiodol marking for small pulmonary nodules, has a potential risk of distribution in the surrounding lung structure. There are no reports about detailed accumulation and lipiodol. Purpose To evaluate computed tomography (CT) findings after before thoracoscopic surgery nodules. Material Methods Sixty-four consecutive CT-guided markings 103 nodules were performed 55 patients. Lipiodol (0.2–0.4 mL) was injected using 21-gauge needle near nodule. The appearance spots...
Abstract Aim Due to the lack of national perinatal registries, population‐wide descriptive statistics on cesarean deliveries in Japan are unknown. We aim describe for overall and multiple pregnancies using National Database health insurance claims. Methods calculated prefectural delivery rates 2014. described maternal morbidities (e.g., blood transfusion) place type institutions providing prenatal care. Results The were 18.6% 82.7% women with pregnancies. Prefectural varied from 12.5% 24.2%...
Pneumothorax is the most common complication after computed tomography (CT)-guided lung biopsy. The presence of a pneumothorax per se does not complicate patient management, but an increasing pneumothorax, making chest tube placement necessary, highly problematic.To evaluate efficacy and limitations simple aspiration air from pleural space to prevent increased avoid in cases following CT-guided biopsy.The subjects our study were 642 consecutive lesions 594 patients for which percutaneous...
Abstract Background The left dorsolateral prefrontal cortex (DLPFC) is involved in early-phase manual dexterity skill acquisition when cognitive control processes, such as integration and complexity demands, are required. However, the effectiveness of DLPFC transcranial direct current stimulation (tDCS) on motor learning whether its depends demand target task unclear. This study aimed to investigate tDCS over improves non-dominant hand performance determine if efficacy task. Methods In this...
Previous neuroimaging studies have reported dual-task interference (DTi) and deterioration of task performance in a cognitive-motor dual (DT) compared to that single (ST). Greater frontoparietal activity is neural signature DTi; nonetheless, the underlying mechanism cortical network DTi still remains unclear. This study aimed investigate regional brain changes during induced by highly demanding DT. Thirty-four right-handed healthy young adults performed spiral-drawing task. They underwent...
Background Tris-acryl gelatin microspheres (TAGM) and sponge particles (GS) have been used in uterine artery embolization (UAE) for leiomyoma. No direct comparisons of both embolic agents reported. Purpose To compare the outcomes UAE with TAGM those GS Material Methods This was a non-randomized, single-institute, non-inferiority study. Between July 2008 August 2015, 67 consecutive patients symptomatic leiomyoma underwent UAE. first 49 following 18 patients. The primary endpoint tumor...
Background: Various treatments for hepatocellular carcinoma (HCC) beneath the diaphragm have been reported. Transpulmonary radiofrequency (TPRF) ablation HCC has developed as a safe treatment, but pneumothorax reported most common complication of TPRF ablation. Purpose: To evaluate relationship between incidence and various variables after Material Methods: Seventy-six sessions unresectable were performed in 66 patients (19 women, 47 men; mean age 69.6 years) under computed tomography...
Although portal and/or splenic vein thrombosis after partial embolization (PSE) is a well-known complication, few reports evaluating risk factors have been published.To investigate and clinical course of PSE.Sixteen patients with severe hypersplenism underwent PSE between March 2005 April 2008. The correlation detected on multidetector row CT (MDCT) various were retrospectively reviewed. Further, the was observed follow-up MDCT.Splenic in eight (50%) MDCT images taken within 9 days PSE. In...
This study evaluated the feasibility and safety of transjugular intrahepatic portosystemic shunt (TIPS) procedure using hepatic artery-targeting guidewire technique for puncture step.We retrospectively reviewed 11 consecutive patients (5 men 6 women, aged 46-76 years (mean 64 years)) with portal hypertension in whom TIPS was performed. As first step all cases, a micro-guidewire inserted into arterial branch accompanying venous through microcatheter coaxially advanced from 5-French catheter...
Patients with endometrial cancer can present various complicating illnesses, including obesity, diabetes mellitus, hypertension and advanced aging. These patients are at high risk of severe post-operative complications. Thus, the question whether or not to perform systemic pelvic para-aortic lymphadenectomy remains controversial for all patients. It is reported that external iliac lymph nodes most commonly involved in cancer, node (PAN) metastases spread via a route shared by common nodes....
Objective: To retrospectively evaluate the frequency and risk factors for developing thrombus in a systemic vein such as infrarenal inferior vena cava or iliac vein, which balloon-occluded retrograde transvenous obliteration (B-RTO) catheter was indwelled.Materials Methods: Forty-nine patients who underwent B-RTO gastric varices were included this study.The procedure performed from right femoral retained overnight all patients.Pre-and post-procedural CT scans compared order to development of...
We aimed to evaluate the feasibility and safety of selective arterial embolization for refractory knee hemarthrosis.Transcatheter hemarthrosis was performed on five female patients (median age, 77 years; range, 71-80 years) between May 2009 September 2012. Selective feeding artery using a 2.5 F microcatheter coaxially advanced from 5 catheter with its tip positioned in superficial femoral artery. One- or two-millimeter gelatin particles were used as embolic agents.In all patients,...
The purpose of this study was to examine the incidence new or recurrent venous thromboembolism (VTE) after retrieval inferior vena cava (IVC) filters and risk factors associated with such recurrence. Between March 2001 September 2008, at our institution, implanted retrievable were retrieved in 76 patients. VTE reviewed numerous variables analyzed assess for redevelopment filter retrieval. In 5 (6.6%) patients, worsening seen filter. Three patients (4.0%) had deep thrombosis (DVT) lower...
The purpose of our study was to evaluate the usefulness N-butyl cyanoacrylate (NBCA) in addition microcoils percutaneous implantation a port-catheter system for repeated hepatic arterial infusion chemotherapy with fixed-catheter-tip method.We retrospectively studied 166 consecutive patients unresectable advanced liver cancer whom percutaneously implanted its tip fixed at gastroduodenal artery microcoils. In 107 patients, NBCA also used catheter fixation. We compared this group control cohort...
We investigated the effects of lasers irradiation on exposed dentinal tubule. Human tooth specimens with tubule orifices were used. Three types (CO(2) laser, Er:YAG laser and Ga-Al-As laser) employed. The parameters 1.0 W in continuous-wave mode an time 30 s for CO(2) mJ 60 laser. A non-irradiated group was used as a control. After irradiation, surface each sample observed using SEM. Afterwards, all samples immersed methylene blue dye solution order to evaluate penetration observe change...
The purpose of our investigation was to determine the safety and usefulness embolisation procedures in balloon occluded retrograde transvenous obliteration (BRTO) as treatment gastric varices after portal hypertension.Between June 2004 August 2009, 40 patients underwent BRTO for that occurred hypertension institution. When large collateral vessels had developed drainage veins other than gastro-renal shunt, these were embolised prior BRTO.Embolisation performed 18 16 cases before BRTO....
