Impact of New Quick Gold Nanoparticle-Based Cortisol Assay During Adrenal Vein Sampling for Primary Aldosteronism.

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 cortisol assay (QCA) that uses immunochromatography and gold nanoparticles and can be performed either semiquantitatively or quantitatively.

Emergent thoracic endovascular aortic repair for acute type-B aortic dissection with malperfusion by matsui-kitamura stent graft.

Acute type-B aortic dissection with malperfusion is a serious cardiovascular condition associated with high morbidity and mortality. Recent studies have investigated the efficacy of thoracic endovascular aortic repair (TEVAR) as treatment for acute aortic dissection. In this report, we present a case of acute type-B aortic dissection complicated with malperfusion, which was successfully treated with emergent TEVAR for entry closure by a Matsui-Kitamura stent graft (MKSG).

Risk factor analysis of thoracic endovascular repair using the Matsui-Kitamura stent graft for acute aortic emergencies in the descending thoracic aorta.

Objective: In recent years, thoracic endovascular aneurysm repair (TEVAR) has been attempted for acute aortic emergencies (AAEs). However, the risk factors for achieving good results have not been identified. Besides focusing on Acute Physiology and Chronic Health Evaluation (APACHE) II score as a general indicator of patient condition, we analyzed both preoperative factors and intraoperative/postoperative factors.

An experimental study of type I endoleak repair with a suturing device.

Purpose: An experimental study was done to investigate repair of type I endoleaks in thoracic aortic aneurysms using the T-Fix suturing device (Smith & Nephew Co, Ltd, London, United Kingdom).

Description: A saccular descending aortic aneurysm was made in 5 pigs experimentally. A stent graft was deployed to produce a proximal type I endoleak.

Stent-graft deployment to treat a perigraft seroma formed after descending thoracic aortic surgery.

Purpose: To report a case of stent-graft implantation for a perigraft seroma that formed after descending thoracic aortic surgery.

Case Report: A 70-year-old woman presented with a perigraft seroma after a descending thoracic aortic surgery 10 years ago in which a polytetrafluoroethylene graft was used. Chest radiography and computed tomography confirmed the presence of a large perigraft seroma.
