Spontaneous haemothorax caused by a ruptured pulmonary arterio-venous malformation: A manifestation of hereditary haemorrhagic telangiectasia in pregnancy.

We report our experience of managing a massive haemothorax caused by a ruptured, previously unknown, pulmonary arteriovenous malformation (pAVM) at 34 + 5 weeks of gestation, which proved to be a manifestation of hereditary haemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome. The patient underwent an emergency caesarean section under general anaesthesia after placement of a chest tube and gave birth to a healthy infant. A postoperative thoracic computed tomography angiography highlighted the presence of the large pAVM.

Non-Neurological Complications after Mechanical Thrombectomy for Acute Ischemic Stroke: A Retrospective Single-Center Study.

Introduction: The global burden of stroke is high and mechanical thrombectomy is the cornerstone of the treatment. Incidences of acute non-neurological-complications are poorly described. Improve knowledge about these complications may allow to better prevent, detect and/or manage them.

Haemothorax in a Pregnant Woman Secondary to Rupture of a Pulmonary Arteriovenous Malformation.

Unlabelled: Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between the arteries and veins of the pulmonary vasculature leading to a right-to-left shunt. We report the case of a pregnant patient who presented with chest pain revealing a haemothorax secondary to the rupture of an arteriovenous malformation. The diagnosis was made during arteriography after simultaneous performance of an urgent caesarean section and thoracic drainage.

A Randomized Trial of Intravenous Alteplase before Endovascular Treatment for Stroke.

Background: The value of administering intravenous alteplase before endovascular treatment (EVT) for acute ischemic stroke has not been studied extensively, particularly in non-Asian populations.

Methods: We performed an open-label, multicenter, randomized trial in Europe involving patients with stroke who presented directly to a hospital that was capable of providing EVT and who were eligible for intravenous alteplase and EVT. Patients were randomly assigned in a 1:1 ratio to receive EVT alone or intravenous alteplase followed by EVT (the standard of care).

Periprocedural safety and technical outcomes of the new Silk Vista Baby flow diverter for the treatment of intracranial aneurysms: results from a multicenter experience.

Purpose: The aim of our study was to assess the technical success and the safety of this new low-profile flow diverter Silk Vista Baby (SVB) by evaluating the intraprocedural and periprocedural complication rate.

Material/methods: Clinical, procedural, and angiographic data were analyzed.

Results: 41 consecutive patients (28 women; age average 50.

Endovascular treatment of intracranial aneurysms with the Woven EndoBridge device: mid term and long term results.

Purpose: To evaluate the clinical and anatomical results of treatment of intracranial aneurysms (IA) with the Woven EndoBridge (WEB) device, with emphasis on mid term and long term follow-up.

Methods: Between November 2010 and November 2015, we retrospectively identified, in our prospectively maintained database, all patients treated by WEB device placement for an IA at three institutions. Clinical charts, procedural data, and angiographic results were reviewed.

Mechanical endovascular thrombectomy for acute ischemic stroke: a retrospective multicenter study in Belgium.

Clinical trials have shown a beneficial effect of mechanical thrombectomy in acute ischemic stroke patients treated within six up to even 12 h after symptom onset. This treatment was already performed in selected hospitals in Belgium before completion of the randomized controlled trials. Outcome data on these procedures in Belgium have not been published.

Stent-assisted coiling of unruptured intracranial aneurysms: long-term follow-up in 164 patients with 183 aneurysms.

Purpose: Stent-assisted coiling (SAC) is increasingly used to treat complex unruptured intracranial aneurysms (UIA) including wide-necked and fusiform IA. However, few data are available over the long-term results of this technique. We report our 9-year-experience of SAC of UIA.

Endovascular treatment of proximal superior middle cerebral artery aneurysms.

Introduction: Aneurysms superiorly located on the proximal segment of the middle cerebral artery (PMCAA) are rare and challenging to treat. No information is available regarding their management by endovascular approach. The aim of this study was to report our experience with endovascular treatment (EVT) of PMCAA.

MR imaging of iron phagocytosis in intraluminal thrombi of abdominal aortic aneurysms in humans.

Purpose: To prospectively determine if superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance (MR) imaging could help visualize leukocyte phagocytic activities in human abdominal aortic aneurysms (AAAs).

Materials And Methods: This study was approved by the institutional ethics committee; all patients gave informed consent. Preoperative MR imaging data, including unenhanced and SPIO-enhanced T1-, T2*-, and T2-weighted transverse images of the entire AAA, obtained 1 hour after contrast enhancement from 15 patients (mean age, 72.

A rare variant of persistent trigeminal artery: cavernous carotid-cerebellar artery anastomosis--a case report and a systematic review.

We report a very rare anomalous anatomic variant of the cavernous internal carotid artery supplying directly the posterior inferior cerebellar artery, with no basilar artery opacification. A systematic review as well as a description of other variants of trigeminal-cerebellar anastomosis is given.

Free-breathing accelerated gadolinium-enhanced MR Angiography in the Diagnosis of Renovascular Disease.

Objective: The purpose of this study was to assess the feasibility and accuracy of accelerated free-breathing and breath-hold gadolinium-enhanced MR angiography of the main renal arteries compared with digital subtraction angiography.

Materials And Methods: Renal MR angiograms and catheter angiograms of 47 patients (19 men, 28 women; mean age, 68.1 +/- 15.

Quadruple-phase MDCT of the liver in patients with suspected hepatocellular carcinoma: effect of contrast material flow rate.

Objective: The purposes of this study were to evaluate the effect of contrast material flow rate (3 mL/sec vs 5 mL/sec) on the detection and visualization of hepatocellular carcinoma (HCC) with MDCT and the safety profile of iodixanol at different injection rates.

Subjects And Methods: In a prospective, randomized multicenter trial, 97 patients (83 men and 14 women, with a mean age of 64 years) suspected of having HCC underwent quadruple-phase (double arterial, portal venous, delayed phase) 4-16-MDCT. Patients were randomized to receive iodixanol, 320 mg I/mL (1.
