Embolization of renal arteries by an autoclot with thrombin was used in 16 patients. Hypernerphroma was diagnosed in 13 patients, pyonephroses--in 2 patients and adrenal tumor--in one patient. In two patients catheterization of the renal artery failed due to atherosclerotic injury of the aorta. Nephrectomy was fulfilled in 14 patients. In two patients the treatment involved only embolization of the renal artery. The important part is played by adequate anesthesia. The authors highly estimate the method and recommend it for wider use in clinics.

Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).

Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.

Objective: The aim of this study was to assess the effectiveness of non-invasive coronary computed tomography angiography (CTA) as an alternative to traditional invasive coronary angiography (ICA) for preoperative evaluation of low risk patients with an indication for non-emergent mitral surgery and to assess any difference in adverse outcomes from this strategy.

Methods: This was a retrospective cohort study from a single center with data collected from July 2014 - June 2020 for 1576 patients undergoing mitral valve surgery of all etiologies - excluding patients requiring coronary artery bypass surgery. We performed a 1:2 propensity score matching for patients evaluated with CT (n=345) to those evaluated with ICA (n=602).

Background: According to the latest Society for Vascular Surgery (SVS) guidelines, carotid revascularization for asymptomatic individuals should be offered if the perioperative stroke/death rate does not exceed 3%. Heart failure (HF) has been associated with reduced survival rates following carotid revascularization, which may significantly impact the risk-benefit decision of treating asymptomatic patients with HF. This study aimed to evaluate the 30-day postoperative risks in asymptomatic patients with newly diagnosed and/or decompensated HF undergoing carotid endarterectomy (CEA) and carotid artery stenting (CAS).

Aneurysmal rupture in microscopic polyangiitis: a case-based review.

Clin Rheumatol

January 2025

Department of Medical Laboratory Science, Faculty of Health Sciences, Hokkaido University, Sapporo, Hokkaido, Japan.

Microscopic polyangiitis (MPA) affects small and medium vessel, which sometimes leads to arterial aneurysms. In English database, only 15 reports refer to ruptured aneurysms in MPA. We experienced a fatal case with MPA who developed multiple visceral aneurysms, resulting in rupture of the hepatic aneurysm.

BACKGROUND Arterial hypertension in pediatric patients often presents complex diagnostic and therapeutic challenges. The diagnosis of hypertension in children is based on different guidelines than in adults, with arterial hypertension in children defined as systolic and/or diastolic blood pressure values at or above the 95th percentile for age, sex, and height. Unlike adult populations, it is predominantly secondary in etiology, with conditions such as renovascular hypertension as common causes.
