INTRODUCTION: Polyarteritis nodosa is a necrotizing vasculitis that mainly affects small and medium-sized arteries in skin and internal organs. Neurological involvement is reported in around 25% of cases: ischemic stroke is relatively common, but haemorrhagic lesions are extremely rare. Subarachnoid haemorrhage in polyarteritis nodosa is an uncommon expression of this disease, mostly associated with aneurism rupture. To the best of the authors' knowledge, there is just one published case in pediatric age with polyarteritis nodosa and subarachnoid haemorrhage with no underlying aneurismal disease...

Extra-renal complications of autosomal dominant polycystic kidney disease (ADPKD) are often unrecognized. Liver cysts are usually benign, but may cause chronic pain, may interfere with nutrition and may necessitate partial liver resection or even liver transplant. Somatostatin analogs may be an alternative therapy. Cerebral aneurisms are rare, but devastating. They must be investigated in case of positive familial history. Cardiac valvulopathies will be searched for by echocardiography. Abdominal wall herniae are often identified during the physical exam in ADPKD patients...

BACKGROUND: Several benefits have been described over the years of the transradial versus femoral endovascular approach to cardiac interventions. Consequently, its use has become habitual at most centers that perform cardiac catheterizations. This paper details a right transradial approach, incorporating a variety of coils or flow diverters, which can be utilized for the endovascular treatment of different cerebral aneurysms. METHODS: From 2014 to 2016, we performed 40 endovascular procedures to treat cerebral aneurysms adopting the same right transradial approach...

INTRODUCTION: Subarachnoid hemorrhage (SAH)represents hemorrhage in the space between arachnoidea and pia mater, due to aneurysm burst, spontaneously or as a consequence of trauma. It is condition that occurs more common in women than men, and its most common complications are rebleeding and vazospasm. As a result of vasospasm, develops ischemia in the portion of brain tissue that can cause additional neurological deficit. Transcranial Doppler Sonography (TCD) is a noninvasive ultrasound diagnostic method that allows monitoring of the state of intracerebral hemodynamics...

Intercellular communication among autonomic nerves, endothelial cells (ECs), and vascular smooth muscle cells (VSMCs) plays a central role in an uninterrupted regulation of blood flow through vascular contractile machinery. Impairment of this communication is linked to development of vascular diseases such as hypertension, cerebral/coronary vasospasms, aortic aneurism, and erectile dysfunction. Although the basic concept of the communication as a whole has been studied, the spatiotemporal correlation of ECs/VSMCs in tissues at the cellular level is unknown...

All inflammatory changes in the vessel wall are defined as vasculitis. Pediatric vasculitis may present with different clinical findings. Although Henoch-Schönlein purpura which is the most common pediatric vasculitis generally recovers spontaneously, it should be monitorized closely because of the risk of renal failure. Although Kawasaki disease is easy to diagnose with its classical findings, the diagnosis may be delayed in case of incomplete Kawasaki disease. Kawasaki disease should be considered especially in infants in case of prolonged fever even if the criteria are not fully met and intravenous immunoglobulin treatment should be administered without delay in order to prevent development of coronary artery aneurism...

We report a case of subarachnoid hemorrhage due to rupture of a cerebral aneurysm in a 29-year-old woman in the 34th week of pregnancy. The aneurysm at the anterior communicating artery was up to 10 mm in diameter on magnetic resonance imaging and scheduled for emergent coil embolization. Simultaneously, obstetricians determined that cesarean section should be performed. Maintaining anesthesia by propofol and remifentanil, coil embolization was first performed to avoid aneurism re-rupture, and the patient was then transferred from an angiography room to an operating room where a cesarean section was performed...

During open abdominal aortic aneurism (AAA) repair cerebral blood flow is challenged. Clamping of the aorta may lead to unintended hyperventilation as metabolism is reduced by perfusion of a smaller part of the body and reperfusion of the aorta releases vasodilatory substances including CO2. We intend to adjust ventilation according end-tidal CO2 tension (EtCO2) and here evaluated to what extent that strategy maintains frontal lobe oxygenation (ScO2) as determined by near infrared spectroscopy. For 44 patients [5 women, aged 70 (48-83) years] ScO2, mean arterial pressure (MAP), EtCO2, and ventilation were obtained retrospectively from the anesthetic charts...

The aim of the present work is to describe the integration of a mathematical model for the baroreceptor reflex mechanism to provide regulatory action into a dimensionally heterogeneous (3D-1D-0D) closed-loop model of the cardiovascular system. Such heterogeneous model comprises a 1D description of the arterial tree, a 0D network for the venous, cardiac and pulmonary circulations and 3D patient-specific geometries for vascular districts of interest. Thus, the detailed topological description of the arterial network allows us to perform vasomotor control actions in a differentiated way, while gaining insight about the effects of the baroreflex regulation over hemodynamic quantities of interest throughout the entire network...

In gamma knife stereotactic radiosurgery (GKSRS) treatment planning, 1.5 tesla (T)-magnetic resonance imaging (MRI) is normally used to identify the target lesion. Image artifacts and distortion arise in MRI if a titanium clip is surgically implanted in the brain to treat cerebral aneurysm. 3-T MRI scanners, which are increasingly being adopted, provide imaging of anatomic structures with better clinical usefulness than 1.5-T MRI machines. We investigated signal defects and image distortions both close to and more distant from the titanium clip in 1...
