CONTEXT Adrenal vein sampling (AVS) is essential for identifying a surgically curable form of primary aldosteronism (PA), but accurate placement of the sampling catheter is technically challenging. Intraprocedural cortisol measurement can confirm the catheter's position, thereby increasing the AVS success rate. OBJECTIVE AND METHODS We developed a quick(More)
CONTEXT Although adrenal vein sampling (AVS) is the standard method for subtype diagnosis in primary aldosteronism (PA), protocol details including the sampling position in the adrenal vein are not standardized. OBJECTIVE To establish the optimum sampling position in the left adrenal vein based on postoperative outcome in PA patients. DESIGN AND SETTING(More)
OBJECTIVES Adrenal vein sampling (AVS) is the standard criterion for the subtype diagnosis in primary aldosteronism (PA). Although lateralized index (LI) ≥4 after cosyntropin stimulation is the commonly recommended cut-off for unilateral aldosterone hypersecretion, many of the referral centres in the world use LI cut-off of <4 without sufficient evidence(More)
PURPOSE To examine whether simultaneous kindling of bilateral hippocampi [bilateral kindling (BK)] could accelerate the achievement of seizures by the breakdown of kindling antagonism or decelerate the achievement of seizures by its enhancement. METHODS The hippocampi of 17 adult rabbits were simultaneously kindled bilaterally according to Goddard's(More)
A 77-year-old man developed pulmonary tumor thrombotic microangiopathy (PTTM) 2 days after undergoing transurethral resection for urothelial carcinoma (G3) of the urinary bladder and died of respiratory failure 6 days later. Histological findings demonstrated marked intimal fibrocellular proliferation, fibrin thrombi, and both cancer cells and fibrin(More)
CONTEXT In adrenal vein sampling (AVS) for patients with primary aldosteronism, the contralateral ratio of aldosterone/cortisol (A/C) between the nondominant adrenal vein and the inferior vena cava is one of the best criteria for determining lateralized aldosterone secretion. Despite successful cannulation in some patients, the A/C ratios in the adrenal(More)
Common bile duct stones were demonstrated as high-density objects on CT in 22 of 45 cases. About 96% of the remaining cases (22 of 23) exhibited other abnormal CT findings which included common bile duct dilatation, concomitant gallbladder stones, and/or presence of intraductal air. CT is a useful diagnostic modality in the evaluation of patients with(More)
OBJECTIVE Although corticotropin is a representative secretagogue of aldosterone, the utility of the cosyntropin stimulation test (C-ST) in diagnosing primary aldosteronism (PA) has not been elucidated. Aim of the study was to evaluate the clinical utility of C-ST for confirmatory testing and subtype classification of PA. DESIGN, SETTING AND PATIENTS In(More)
Context The number of centers with established adrenal venous sampling (AVS) programs for subtype diagnosis of primary aldosteronism (PA) is limited. Objective Aim was to develop an algorithm for AVS based on subtype prediction by computed tomography (CT) and serum potassium. Design A multi-institutional retrospective cohort study in Japan. Patients(More)
Acute pulmonary thromboembolism (APTE) and deep venous thrombosis (DVT) are categorized into venous thromboembolism. APTE is one of the most critical post-operative complications because of its high mortality. Meanwhile, DVT is responsible for more than 80-95% of APTE cases. APTE occurred in 6 patients and DVT in 3 patients in the post-operative period(More)
