BACKGROUND: Chronic spontaneous urticaria (CSU) is one of the commonest diseases in allergological and dermatological practice. It constitutes an interdisciplinary problem, and its pathogenesis is not always easily determined. It has been suggested that metabolic syndrome and hyperlipidaemia are more frequent in patients with CSU, but the influence of overweight and obesity on the development of CSU has not been thoroughly investigated. AIM: To assess the association between body parameters and the development of CSU...

BACKGROUND: Few studies have demonstrated detailed physical risk factors of hemorrhagic complications (HC) associated with the Angio-Seal closure device. This retrospective study aimed to identify the risk factors of HC due to Angio-Seal use. METHODS: Data from 143 cases that underwent neurointerventional procedures that involved puncturing the femoral artery and that used an Angio-Seal to close the puncture site were reviewed. We divided these cases into HC and no HC groups and retrospectively compared age, sex, past medical and preference history, body mass index (BMI), femoral artery depth, dual antiplatelet therapy use, activated clotting time, general anesthesia use, sheath size, right femoral artery puncture, and treatment time...

OBJECTIVE: To determine whether rehearsal using patient-specific information loaded onto an endovascular simulator prior to carotid stenting improves procedural efficiency and outcomes. METHODS: Patients scheduled for carotid artery stenting who had adequate preoperative computed tomography (CT) imaging were considered for enrollment. After obtaining informed consent, patients were randomized to control versus rehearsal groups. Those in the rehearsal group had their CT scans loaded into an endovascular simulator (Angio Mentor) followed by case rehearsal by the attending on the simulator within 24 hours prior to the procedure; control patients underwent routine carotid stenting without rehearsal...

OBJECTIVE: Pulmonary Embolism (PE) is an emergency condition that requires immediate treatment. As the symptoms and the risk factors are nonspecific, PE differential diagnosis is often required. Even if angio-CT is considered the gold standard for PE diagnosis, the frequent allergic condition and/or chronic renal failure of patients make, in most cases, not possible the use of contrast enhancement in emergency with even more increasing use of Lung Perfusion Scintigraphy (LPS), as a simple and fast examination with no preparation/contraindication...

This study investigated for the first time brain ischemic involvement in 19 consecutive neurologically asymptomatic PNH patients by non-enhanced cerebral MRI, and by intracranial arterial and venous angio-MRI. Eleven cases (58%, 7 aged <65) showed pathological findings: 9 white matter (WM) abnormalities related to chronic ischemic small vessel disease, 2 a focal abnormality >5 mm, and 5 cases a score >4 by the age-related white matter changes (ARWMC) scale. Compared with age and sex-matched controls (1:2 ratio), patients showed an increased frequency of periventricular WM vascular degeneration (32% versus 5...

Tumours can be viewed as aberrant tissues or organs sustained by tumorigenic stem-like cells that engage into dysregulated histo/organogenetic processes. Paragangliomas, prototypical organoid tumours constituted by dysmorphic variants of the vascular and neural tissues found in normal paraganglia, provide a model to test this hypothesis. To understand the origin of paragangliomas, we built a biobank comprising 77 cases, 18 primary cultures, 4 derived cell lines, 80 patient-derived xenografts and 11 cell-derived xenografts...

OBJECTIVES: Cerebral arterio-venous malformations (AVM) are considered congenital lesions, emerging as an important cause of haemorrhagic stroke in children. The potential influence of age on clinical presentation and angio-architecture have been analysed extensively in the last years. Yet, comparative studies comprising ascending age groups may be limited in their conclusions, especially when comparing young children and adults. It is the aim of this study to evaluate characteristic clinical and angiographic features of AVM within a paediatric subgroup and their correlation to age at presentation...

BACKGROUND: The technical and clinical success of the thoracic aortic endovascular procedures rests mainly on the choice of the proximal sealing zone (PSZ). The latter can be the affected by multiple complications, all of them having a potential gravity and a direct link with the quality of the PSZ. The objective of this study was to analyze the risk factors of the occurrence of complications of the PSZ. METHODS: Between 2007 and 2015, all the patients treated by a thoracic stentgraft in zones 2, 3, or 4 were retrospectively reviewed, with analysis of the pre- and postoperative angio-CT...

Long-term iliofemoral complications induced by radiation include vascular (arterial and venous) lesions, nervous lesions and soft tissue loss that can be cutaneous and subcutaneous and potentially lead to radionecrosis with vessel exposure. We present five cases of groin radionecrosis. There were three men and two women (age 30-73 years). Radiotherapy had been delivered 15 years earlier in three cases, and 2 years earlier in two cases. Symptoms were intermittent claudication (n=1), critical ischemia (n=1), and septic hemorrhage (n=1)...

We herein report a serious vascular complication of diagnostic cardiac catheterization due to an embolization of an Angio-Seal closure device causing acute lower limb ischemia. The Angio-Seal was deployed via the right femoral artery following the catheterization which embolized several hours later to the right popliteal artery. Fogarty embolectomy restored perfusion to the right lower limb; however, compartment syndrome subsequently developed which required evacuation of a hematoma and repair of right popliteal artery...

This article discusses the protocol for myocardial perfusion scintigraphy performed with single-photon emission computed tomography (SPECT). Indications for SPECT are listed with consideration given to the results of the increasingly more common angio-CT examinations of the coronary arteries (multislice computed tomography). The paper also presents basic information about interpreting the results, including the scores of left ventricle myocardial perfusion using the 17-segment polar map, and explains the concept of total perfusion deficit...

Pregnancy and postpartum are very high-risk periods for venous thromboembolism events (TEE), which seems to extend far beyond the classical 6-8 weeks after childbirth. Pulmonary embolism (PE) is one of the 3 main causes of direct maternal death in western countries. Between 2010 an 2012 in France, 24 deaths were related to PE giving a maternal mortality ratio of 1/100,000, which is not different from the former report (2007-2009). PE is responsible of 9% of maternal deaths, in equal position with postpartum hemorrhage and amniotic fluid embolism...

Stroke is a rare event during pregnancy (10/100,000) and can be ischemic (24%), hemorrhagic (74%) or both (2%). Pregnancy probably increases the risk even if it is discussed for arteriovenous malformation (AVM), aneurismal subarachnoid hemorrhage (SAH) and cavernomas. Between 2010 and 2012, 31 maternal deaths were associated with stroke. In 22 cases, stroke was the direct cause of death giving a maternal mortality ratio of 0,9/100,000 witch is not different from the former report (2007-2009). There were 2 cerebral thrombophlebitis, 2 ischemic strokes and 18 hemorrhagic strokes (4 SAH, 2 AVM)...
