We report a patient with life-threatening hematemesis caused by the rupture of a ductus aneurysm into the esophagus, which was successfully treated by coil embolism for the esophageal fistula through the aorta and subsequent thoracic endovascular aortic replacement. Second-stage therapy was performed surgically after proactive antibiotic treatment and in consideration of the patient's improved general condition. This included debridement with drainage, aortic encasement with remnant aneurysmal wall, omentopexy, and jejunostomy...

Background Patients with polycystic kidney disease have a higher prevalence of intracranial aneurysms and may progress to renal failure requiring transplantation. The endovascular treatment of intracranial aneurysms may improve prognosis, since rupture often causes premature death or disability, but the nephrotoxicity risk associated with contrast medium must be always considered in cases of renal impairment. Methods A 55-year-old female patient with polycystic kidney disease and grafted kidney associated with anterior communicant artery aneurysm was successfully treated by embolization...

INTRODUCTION: There is uncertainty as to the best management of arteriovenous malformations of the brain (bAVM). However, the Spetzler-Martin grade (SMG) has been validated as an effective determinant of surgical risks. We performed a systematic review for the best evidence regarding the management of bAVM for series that incorporate an analysis based upon SMG. EVIDENCE ACQUISITION: Medline, Embase, Scopus and Cochrane databases were searched for series between January 2000 and January 2018, with a minimum of 100 cases and that incorporated SMG stratification...

Vein of Galen aneurysmal malformation is a congenital anomaly of the cerebral vasculature representing 30% of all paediatric vascular malformations. We conducted whole exome sequencing in 19 unrelated patients presenting this malformation and subsequently screened candidate genes in a cohort of 32 additional patients using either targeted exome or Sanger sequencing. In a cohort of 51 patients, we found five affected individuals with heterozygous mutations in EPHB4 including de novo frameshift (p.His191Alafs*32) or inherited deleterious splice or missense mutations predicted to be pathogenic by in silico tools...

Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the hair matrix of anagen hair follicles, due to the sensitivity of these cells to radiation. The characteristics of radiation-induced temporary alopecia are similar to those of alopecia areata as follows: (1) clinical findings of well-defined alopecic patches and (2) dermoscopic findings of yellow dots, black dots, and short vellus hairs...

BACKGROUND AND PURPOSE: Endovascular embolization of intracranial aneurysms with hydrogel-coated coils lowers the risk of major recurrence, but technical limitations (coil stiffness and time restriction for placement) have prevented their wider clinical use. We aimed to assess the efficacy of softer, second-generation hydrogel coils. METHODS: A randomized controlled trial was conducted at 22 centers in France and Germany. Patients aged 18 to 75 years with untreated ruptured or unruptured intracranial aneurysms measuring 4 to 12 mm in diameter were eligible and randomized (1:1 using a web-based system, stratified by rupture status) to coiling with either second-generation hydrogel coils or bare platinum coils...

Objective Pipeline embolization devices (PED) are commonly used for endovascular treatment of cerebral aneurysms but changes in intracranial hemodynamics after PED deployment are poorly understood. Here, we assess middle cerebral artery (MCA) and systemic blood pressure before and after PED treatment. Methods Records of patients with cerebral aneurysms proximal to the internal carotid artery terminus treated with PED at our institution between 2015 and 2017 were retrospectively reviewed. Patients were included if ipsilateral MCA pressure measurements were available...

BACKGROUND: The choice of appropriate antiplatelet therapy prior to the Pipeline Embolization Device (PED) placement is usually guided by platelet function testing such as light transmission aggregometry (LTA). In this study, we aimed to define the optimal threshold LTA value for clopidogrel responsiveness to predict the risk of post-procedural thromboembolic complications and to help guide appropriate antiplatelet regimen. MATERIALS AND METHODS: A prospectively maintained database at an academic neurosurgical center in the United States was retrospectively analyzed from 2014 to 2017 to identify patients with unruptured intracranial aneurysms treated with the PED...

OBJECTIVE Although endovascular therapy is favored for acutely ruptured intracranial aneurysms, hematological factors associated with acute subarachnoid hemorrhage (SAH) may predispose to procedure-related ischemic complications. The aim of this study was to evaluate whether an elevated level of plasma D-dimer, a parameter of hypercoagulation in patients with acute SAH, is correlated with increased incidence of thromboembolic events during endovascular coiling of ruptured aneurysms. METHODS The authors analyzed data from 103 cases of acutely ruptured aneurysms (in 103 patients) treated with endovascular coil embolization at a single institution...

Thoracoabdominal aortic aneurysms are among the most challenging pathologic conditions vascular surgeons have to face. Endovascular treatment brought the prospect of being able to treat these complex aneurysms with less invasiveness and recent outcomes already challenge those of open repair. Plus, this technique offers a therapeutic option for patients who had none, due to significant comorbidities limiting open repair. Spinal cord injury is a major complication after complex aneurysm repair that dramatically affects patient's quality of life, even if technical success - aneurysm exclusion from circulation - has been achieved...
