Introduction Previous studies have suggested relationships between the rupture of intracranial aneurysms and meteorological variables such as season, barometric pressure, and temperature. Our objective was to examine the relationship between the incidence of hospital admissions secondary to aneurysmal subarachnoid hemorrhage (aSAH) and meteorological variables in central New Jersey. Methods The study population consisted of 312 patients who presented to University Hospital in Newark, New Jersey, between January 1, 2003, and December 31, 2008, with aSAH...

Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril...

BACKGROUND AND PURPOSE: A ruptured intracranial aneurysm (IA) is the leading cause of a subarachnoid hemorrhage. This study seeks to define a specific gene whose mutation leads to disease. METHODS: More than 500 IA probands and 100 affected families were enrolled and clinically characterized. Whole exome sequencing was performed on a large family, revealing a segregating THSD1 (thrombospondin type 1 domain containing protein 1) mutation. THSD1 was sequenced in other probands and controls...

BACKGROUND: The lunar cycle and seasons may be associated with rates of rupture of intracranial aneurysms, but the literature is mixed. Studies of the association between the lunar cycle and rates of aneurysm rupture used the eight qualitative moon phases. The purpose of this study was to assess any association of aneurysm rupture with the lunar cycle and with the season. MATERIALS AND METHODS: We retrospectively reviewed all cases of subarachnoid haemorrhage secondary to ruptured intracranial aneurysm treated with endovascular coiling in our institution over a 10-year period...

BACKGROUND: Delayed development of intracranial aneurysms is an extremely rare complication of gamma knife surgery (GKS), and so far only 6 cases have been reported. Furthermore, there are no reported cases after GKS for trigeminal neuralgia (TN). Of the above cases, none referred to the natural history or pathophysiology of GKS-related intracranial aneurysm formation. CASE DESCRIPTION: We treated 2 patients who suffered subarachnoid hemorrhage (SAH) due to ruptures of intracranial aneurysms that developed long after GKS...

BACKGROUND: Due to the continuing improvements in imaging technology, an increasing number of epileptogenic small (≤5mm) unruptured intracranial aneurysms (sUIA) are being diagnosed since 2000. However, they are not systematically described and reviewed until now. CASE DESCRIPTION AND THE LITERATURE REVIEW: We reported 2 patients with sUIA who initially presented with complex partial seizures (CPS). Scalp electroencephalography (EEG) showed the seizures activity arising from the mesial temporal/frontal areas, but conventional magnetic resonance imaging (MRI) scans were normal in both patients...

BACKGROUND: and Purpose: Patients with small (< 5 mm) unruptured intracranial aneurysms (UIAs) are at risk of subarachnoid hemorrhage, but risk assessment of them remains controversy in daily clinical practice. We aimed to identify the risk factors of aneurysmal rupture in these patients. METHODS: We retrospectively analyzed consecutive patients with small UIAs who were admitted to our center between February 2009 and December 2014. The enrolled patients were divided into the ruptured and unruptured groups...

BACKGROUND: Treatment of intra cranial aneurysm (ICA) can sometimes required several procedures. The aim of this study is to analyze the risk of recanalization and rupture recurrence after ICA treatment by endovascular coiling (EVC) or surgical clipping (SC) on a very long follow-up. METHODS: Clinical data of 373 consecutive patients treated in our group between January 1996 and December 2006 as well by EVC as by SC for ruptured (RIA) or unruptured intracranial aneurysm (UIA), were reviewed...

Theoretical properties of a multi-scale opening (MSO) algorithm for two conjoined fuzzy objects are established, and its extension to separating two conjoined fuzzy objects with different intensity properties is introduced. Also, its applications to artery/vein (A/V) separation in pulmonary CT imaging and carotid vessel segmentation in CT angiograms (CTAs) of patients with intracranial aneurysms are presented. The new algorithm accounts for distinct intensity properties of individual conjoined objects by combining fuzzy distance transform (FDT), a morphologic feature, with fuzzy connectivity, a topologic feature...

BACKGROUND AND PURPOSE: The analysis of the pulsation of unruptured intracranial aneurysms might improve the assessment of their stability and risk of rupture. Pulsations can easily be concealed due to the small movements of the aneurysm wall, making post-processing highly demanding. We hypothesized that the quantification of aneurysm pulsation is technically feasible and can be improved by computer-aided post-processing. MATERIALS AND METHODS: Images of 14 cerebral aneurysms were acquired with an ECG-triggered 4D CTA...

Christopher Alan Hilditch, Hemant Sonwalkar, Siddhartha Wuppalapati
Subpial hematoma is a rare type of intracranial hemorrhage with a poor prognosis. A new mechanism to explain subpial Sylvian hematoma formation in acute post-aneurysmal subarachnoid hemorrhage (SAH) was observed during coiling of a posterior communicating artery aneurysm. Multiple small bleeding points from pial branches of the left middle cerebral artery, which were remote from the ruptured aneurysm, were observed on conventional angiography. This bleeding led to the formation of a large expanding subpial Sylvian hematoma...

Rupture of an intracranial aneurysm is a life-threatening event. Only one third of intracranial aneurysms rupture during a patient's lifetime. Accurate markers that predict which intracranial aneurysms rupture and which do not are currently lacking in routine clinical practice. Therefore, the treatment decision is a careful balance between the natural history of the intracranial aneurysm and the risk of intervention based on aneurysm- and patient-specific risk factors. Many of these risk factors are also used to determine the modality of intervention...

We report a case of interhemispheric and bifrontal cortical superficial siderosis in association with two intracranial aneurysms. The patient had no clinical history suggestive of aneurysm rupture, no feature of amyloid angiopathy or other apparent etiology for cortical siderosis. We performed high resolution brain MRI with dark blood T1 sequences before and after IV contrast injection. An anterior communicating aneurysm showed partial wall enhancement on the posterior wall whereas a left posterior communicating aneurysm did not...

Training has been important to facilitate the safe use of new devices designed to repair vascular structures. This paper outlines the generic elements of a training program for vascular devices and uses as an example the actual training requirements for a novel device developed for the treatment of bifurcation intracranial aneurysms. Critical elements of the program include awareness of the clinical problem, technical features of device, case selection, and use of a simulator. Formal proctoring, evaluation of the training, and recording the clinical outcomes complement these elements...
