BACKGROUND: Glanzmann thrombasthenia (GT) is a rare disease with severe insufficiency of platelet function. There are no reports of GT associated with a cerebral hemorrhage. CASE REPORT: A 45-year-old woman had a stuporous mentality. Her computed tomographic (CT) angiography revealed a rupture of the posterior cerebral artery aneurysm. Hunt-Hess grade was 4 points and Fisher grade was 3 points. A clipping of the aneurysm was performed and proceeded to external ventricular drainage for hydrocephalus after 6 days. But, a new hemorrhage was detected several times via a follow-up brain CT. Various blood tests were conducted to evaluate the bleeding tendency, and the GT was diagnosed with PFA-200. The ventriculoperitoneal shunt was performed after the platelets transfusion, and she was discharged without other complications. CONCLUSION: With nonspecific and recurrent intracranial hemorrhage, a GT should be included in the differential diagnosis, which is important in controlling bleeding during the surgery.

OBJECTIVETo explore the diagnosis and treatment strategy of multiple intracranial aneurysms (MIA).

METHODSWe retrospectively analyzed 96 patients with MIA (234 aneurysms). The rupture site was determined on the basis of computed tomographic and angiographic findings, and the supposed ruptured aneurysm was treated with coiling OR clipping. All the patients' records were reviewed including all computed tomographic scans and angiograms.

RESULTSTwelve patients received conservative treatment, 56 patients were treated by endovascular embolization, and 28 patients received clipping; 44 patients received one-stage treatment, and 4 patients needed a second therapy. In 36 patients, only the ruptured aneurysm was eliminated. The clinical outcomes of these 84 patients evaluated by Glasgow Outcome Scale grades were: absence of deficits in 62 patients, minor deficits in 12 patients, major deficit in 8 patients; death occurred in 2 cases. Thirty patients were available for a 6-month follow-up with DSA, which revealed stable occlusion of the aneurysms in 29 patients and the need of a retreatment due to recanalization in only one patient.

CONCLUSIONCorrect localization of the rupture aneurysm based on a comprehensive diagnosis is key to MIA treatment. All the aneurysms should be treated in one session whenever possible to protect the patient from rebleeding.

PURPOSE: Rupture of pre-existing cerebral aneurysms has occasionally been reported as a cause of traumatic subarachnoid hemorrhage (TSAH) and intraparenchymal hemorrhage (IPH). SAH due to rupture of pre-existing cerebral aneurysm is an important differential diagnosis in TSAH. The aim of our study was to determine whether a rupture in a pre-existing cerebral aneurysm could be predicted based on the pattern of hemorrhage on the initial computed tomography (CT) scan in patients with traumatic brain injury (TBI). METHODS: A total of 336 patients who had undergone computed tomography angiography (CTA) for detection of rupture of pre-existing cerebral aneurysm in TBI between the years 2004 and 2013 were retrospectively studied. In order to investigate CT findings of ruptured cerebral aneurysm, patients who had a lesion of SAH, IPH, or IVH were compared with the control group (who had intracranial lesions of contusion, epidural hematoma, subdural hematoma, or hemorrhagic contusion). RESULTS: Fifty eight (17.3%) patients with TSAH harbored cerebral aneurysms, and 45 (13.4%) patients had ruptured cerebral aneurysms. The ruptured aneurysms showed significant association with CT findings of a diffuse hemorrhage in the basal cisterns (29.2%, p=0.003, OR=23.130), unilateral sylvian fissure (13.8%, p=0.039, OR=8.842), anterior interhemispheric fissure (20.0%, p=0.028, OR=14.000), and associated IPH (22.6%, p=0.011, OR=16.333). However, the ruptured aneurysms did not show association with CT findings of hemorrhage on convexities, perimesencephalic cisterns, bilateral sylvian fissure, and IVH (p>0.1). CONCLUSION: Patterns of distribution of SAH and associated IPH on initial CT can be predicted of rupture pre-existing cerebral aneurysm in patients with TBI.

Despite significant regional and risk factor-related variations, the overall mortality rate in patients suffering from aneurysmal subarachnoid hemorrhage (SAH) remains high. Compared to ischemic stroke, which is typically irreversible, hemorrhagic stroke tends to carry a higher mortality, but patients who do survive have less disability. Technologies to monitor and treat complications of SAH have advanced considerably in recent years, but good long-term functional outcome still depends on prompt diagnosis, early aggressive management, and avoidance of premature withdrawal of support. Endovascular procedures and open craniotomy to secure a ruptured aneurysm represent some of the numerous critical steps required to achieve the best possible result. In this review, we have attempted to provide a contemporary, evidence-based outline of the perioperative critical care management of patients with SAH. This is a challenging and potentially fatal disease with a wide spectrum of severity and complications and an often protracted course. The dynamic nature of this illness, especially in its most severe forms, requires considerable flexibility in clinician management, especially given the panoply of available treatment modalities. Judicious hemodynamic monitoring and adaptive therapy are essential to respond to the fluctuating nature of cerebral vasospasm and the varying oxygen demands of the injured brain that may readily induce acute or delayed cerebral ischemia.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

OBJECTIVE: A small branch-incorporated aneurysm is an aneurysm with a small branch incorporated into the sac or the neck. It is one of the most difficult aneurysms to treat with coil embolization. The aim of this study was to evaluate the safety and effectiveness of the coil-protected embolization technique for small-branch incorporated aneurysm. MATERIALS AND METHODS: Fourteen aneurysms (2 ruptured and 12 unruptured) in 12 patients (mean age, 56 years, range, 40-73 years; 6 men and 6 women) were treated with the coil-protected embolization technique during the period between February 2007 and October 2011. Clinical and angiographic outcomes were retrospectively evaluated. RESULTS: All aneurysms were successfully treated without any complications during the procedure. Immediate post-treatment angiographies demonstrated complete or near complete occlusion in 12 and incomplete occlusion in 2 patients. Two patients had a delayed small embolic infarction in the relevant posterior circulation territory and middle cerebral artery territory 10 days and 14 days later, respectively, but both recovered completely or almost completely (modified Rankin scale score [mRS score], 0 and 1, respectively). During the clinical follow-up period (mean, 21 months; range: 2-58 months), all patients reported an mRS score of 0 (n = 10) or 1 (n = 2). Vascular imaging follow-up (catheter angiography: n = 3 and MR angiography: n = 8) was available in 11 aneurysms at 6-12 months. All 11 aneurysms showed complete occlusion except for 1 minor neck recurrence that did not require further treatment. CONCLUSION: In this series of cases, the coil-protected embolization technique seems to be feasible and effective in the treatment of small-branch incorporated aneurysms.

OBJECTIVE: A new double-lumen balloon catheter was being developed for the treatment of cerebral aneurysms. The purpose of this study is to report our initial experience of a double-lumen balloon catheter for the treatment of wide-necked aneurysms. MATERIALS AND METHODS: Seventeen patients (mean age, 63 years; range, 45-80 years) with wide-necked, with or without a branch-incorporated aneurysms, (10 ruptured and 9 unruptured) were treated with balloon-assisted coil embolization using a double-lumen balloon catheter (Scepter C(TM) or Scepter XC(TM)) for 7 months after being introduced to our country. Locations of the aneurysms were posterior communicating artery (n = 7), anterior communicating artery or A2 (n = 7), middle cerebral artery (MCA) bifurcation (n = 3), basilar artery tip (n = 1) and anterior choroidal artery (n = 1). The initial clinical and angiographic outcomes were retrospectively evaluated. RESULTS: Coil embolization was successfully completed in all 19 aneurysms, resulting in complete occlusions (n = 18) or residual neck (n = 1). In one procedure, a thrombus formation was detected at the neck portion of the ruptured MCA bifurcation aneurysm near to the end of the procedure. It was completely resolved with an intra-arterial infusion of Glycoprotein IIb/IIIa inhibitor (Tirofiban, 1.0 mg) without any clinical sequela. There were no treatment-related events in the remaining 18 aneurysms. At discharge, functional neurological state improved in 11 patients (10 patients with ruptured aneurysm and 1 with unruptured aneurysm presenting with mass symptoms) and 6 patients with unruptured aneurysms had no newly developed symptoms. CONCLUSION: In this preliminary case series, the newly developed double-lumen Scepter balloon appears to be a safe and convenient device for coil embolization of wide-necked aneurysms.

OBJECTIVE: To evaluate the prevalence of incidentally found unruptured intracranial aneurysms (UIAs) on the brain MR angiography (MRA) from a community-based general hospital. MATERIALS AND METHODS: This was a prospectively collected retrospective study, carried out from January 2004 to December 2004. The subjects included 3049 persons from a community-based hospital in whom MRA was performed according to a standardized protocol in an outpatient setting. Age- and sex-specific prevalence of UIAs was calculated. The results by MRA were compared with intra-arterial digital subtraction angiography (DSA) findings. RESULTS: Unruptured intracranial aneurysms were found in 137 (5%) of the 3049 patients (M:F = 43:94; mean age, 60.2 years). The prevalence of UIAs was 5% (n = 94) in women and 4% (n = 43) in men, respectively (p = 0.2046) and showed no age-related increase. The most common site of aneurysm was at the distal internal carotid artery (n = 64, 39%), followed by the middle cerebral artery (n = 40, 24%). In total, 99% of aneurysms measured less than 12 mm, and 93% of aneurysms measured less than 7 mm. Direct comparisons between MRA and DSA were available in 70 patients with 83 UIAs; the results revealed two false positive and two false negative results. CONCLUSION: This community-hospital based study suggested a higher prevalence of UIAs observed by MRA than previously reported. These findings should be anticipated in the design and use of neuroimaging in clinical practice.

Subarachnoid hemorrhage (SAH) can be classified as traumatic SAH or spontaneous SAH based on etiology. The traumatic SAH is the common manifestation of head injury and difficult to make a diagnosis in forensic investigation. Based on practical experiences of forensic investigation and relevant references, the main points (SAH identification, examination, death mechanism) were summarized in this article. For the understanding, we try to classify the traumatic SAH into three subtypes: brain injury associated SAH, traumatic rupture of basal cerebral vessels SAH and traumatic focal SAH.

INTRODUCTIONMulti-detector computer tomography angiography (CTA) provides a fast non-invasive assessment of the cerebral vessels, is readily available in an acute setting and can potentially replace invasive digital subtraction angiography (DSA) for the diagnosis of intracranial vascular lesions in an emergency setting. We report our experience in the use of emergent cerebral CTA versus DSA in the assessment of patients presenting acutely with symptoms suspicious of brain aneurysm rupture.

MATERIALS AND METHODSThirty-seven consecutive patients presenting acutely with clinical suspicion of brain aneurysm rupture were evaluated over a 4-month period from January to April 2008. CTA with peripheral intravenous contrast injection was performed on a 32 slice helical scanner. DSA was performed within 48 hours for all cases when CTA was the initial assessment. Studies were assessed via radiology reports using DSA or surgery as the gold standard.

RESULTSAll except for 3 patients had CTA as the initial study. There were 26 cerebral aneurysms detected by CTA in these 37 patients, with 9 negative studies. There were 2 patients with arteriovenous malformations (AVM), 1 with AV fistula (AVF), 1 tumoral bleed, 2 vertebral dissections, and 1 missed sagittal sinus thrombosis (CVT) on CTA. Based solely on CTA assessment, 3 patients had direct surgical clipping of the aneurysm, while 4 proceeded to direct endovascular coiling.

CONCLUSIONEmergent CTA is a non-invasive, reliable and viable alternative to emergent DSA for the assessment of the cerebral vessels in the acute assessment of patients presenting with symptoms suspicious of brain aneurysm rupture. Where positive, it can serve as a guide to therapeutic decisions. Review of CTA source data is essential, especially for small lesions and for post-clipping assessment.
