COMPARATIVE STUDY
Konark Malhotra, James J Conners, Vivien H Lee, Shyam Prabhakaran
The absolute transcranial Doppler (TCD) velocity threshold has been validated as a screening tool for vasospasm after subarchnoid hemorrhage (SAH). We assessed whether relative changes in velocity were superior to absolute TCD thresholds in the detection of symptomatic vasospasm. We reviewed consecutive patients with aneurysmal SAH who underwent serial TCD monitoring and survived at least 7 days. We recorded initial flow velocity (IFV) and maximal flow velocity (MFV) of the middle cerebral artery (MCA) serially up to 14 days from admission...

The blood-brain barrier (BBB) plays a vital role as both a physiologic and physical barrier in regulating the movement of water from the vasculature to the brain. During a subarachnoid hemorrhage (SAH), the BBB is disrupted by a variety of mediators, one of which can result in endothelial cell death. As a result, in the present study, we investigated the role of PUMA (p53 upregulated modulator of apoptosis) following SAH injury in rats. Specifically evaluating whether through the endoplasmic reticulum (ER), PUMA could orchestrate the induction of endothelial cell apoptosis and cause a disruption in the blood-brain barrier integrity...

A 29-year-old woman with refractory hypertension who previously suffered from subarchnoid hemorrhage visited our facility. The diagnosis of renovascular hypertension due to fibromuscular dysplasia was made based on a high level of plasma renin activity (PRA) and aldosterone concentration (AC), and computed tomographic image of bilateral renal artery stenosis/obstruction. Angioplasty, which could be performed only to the left renal artery, failed to regain sufficient BP control. The addition of eplerenone, an aldosterone receptor blocker, to the conventional antihypertensive drugs successfully and safely lowered BP and preserved the renal function despite the persistence of high PRA and AC values...

Oculomotor nerve palsy (ONP) can be the presenting feature of ruptured or an unruptured posterior communicating artery (PcomA) aneurysm. Etiopathogenesis and recovery of ONP following treatment of PcomA aneurysm has been a subject of controversy. Case records of thirteen patients (mean age 42 years (range 19-65 years), M:F: 3:10) with PcomA aneurysm and ONP who underwent surgery over a period of eight years were analyzed. Twelve patients presented with subarchnoid hemorrhage and one had unruptured aneurysm...

BACKGROUND: Intraventricular hemorrhage (IVH) is an independent risk factor for both morbidity and mortality in patients with intracerebral hemorrhage and subarchnoid hemorrhage. The pathophysiological mechanisms by which blood within the ventricles causes brain damage are still poorly understood. SETTINGS AND DESIGN: We developed a canine (dog) model with long-term survival. AIMS: To study the mechanisms of pathological changes associated with IVH...

We present a case of ruptured distal middle cerebral artery aneurysm associated with occlusion of the anterior trunk of the ipsilateral middle cerebral artery. An 83-year-old man had right homonymous hemianopsia and right mild hemiparesis. CT scan revealed hematoma and a perifocal low density area at the left occipital subcortex without subarchnoid hemorrhage (SAH). MRI showed repeated bleeding at the same location as the CT scan. Moreover, cerebral angiograms disclosed an aneurysm on the leptomeningeal anastomosis from the left posterior cerebral artery to the middle cerebral artery...

Anterior communicating artery (Acom) complex and anterior cerebral artery (ACA) are the frequent sites of arterial anomalies. Aneurysms associated with triplicate ACA are rare. Blood blister-like aneurysm (BBA) of the Acom is also very rare. This report presents these two rare types of aneurysms in a 63-year old man who presented with subarchnoid hemorrhage secondary to accessory ACA aneurysmal rupture. During surgery, a BBA of the Acom was also found. Both the aneurysms were treated simultaneously. The BBA bled intraprocedurally but was repaired successfully by neck reconstruction and clipping with the preservation of the parent and the branching arteries...

For the past 50 years the pterional craniotomy has been the standard approach for anterior circulation aneurysms. However, this is a major procedure. As the trend is towards minimally invasive surgery generally, we have been developing a minimally invasive approach for anterior circulation aneurysms - the supraorbital microcraniotomy. We present first 50 patients who underwent this operation after an aneurysmal subarchnoid haemorrhage. The data were collected prospectively between 2001 and 2004. A total of 60 aneurysms were clipped (10 patients had two aneurysms)...

We report two cases of anesthetic management for emergency cesarean sections and craniotomies in patients with intracranial hemorrhage. Case 1: A 32-year-old woman at 33 weeks gestation suffered from subarchnoid hemorrhage due to the rupture of cerebral aneurysm. Case 2: A 38-week-pregnant woman aged 32 developed intracerebral hematoma resulting from ruptured arteriovenous malformation. The weights of the fetuses were estimated to be 1756 g and 1996 g respectively, and they were expected premature. Discussions with obstetricians, neurosurgeons and neonatologists encouraged us to schedule cesarean section followed by craniotomy under general anesthesia...

UNLABELLED: What is already known about this subject? The naturally occurring interlukin-1 receptor antagonist (IL-1RA) markedly protects rodents against ischaemic, excitotoxic and traumatic brain injury, suggesting it may be of therapeutic value. When administered intravenously to patients soon after stroke, IL-1RA is safe and reduces the peripheral inflammatory response. However, IL-1RA is a large protein (17 kDa), which may limit brain penetration, thereby limiting its potential utility in brain injury...

BACKGROUND: Three dimensional rotational angiography (3DRA) is a powerful method for depicting intracranial vascular lesions because of its 3D imaging capability. The purpose of this study was to analyse if 3DRA had reduced the incidence of angiogram-negative subarchnoid haemorrhage (SAH) and which type of aneurysm tended to be overlooked with conventional digital subtraction angiography. METHOD: Angiogram-negative SAH was defined as present in those patients with SAH who had no demonstrable lesion revealed by more than two adequate cerebral angiograms...

BACKGROUND: Brain natriuretic peptide (BNP) is a potent natriuretic and vasodilator factor which, by its systemic effects, can decrease cerebral blood flow (CBF). In aneurysmal subarchnoid hemorrhage (aSAH), BNP plasma concentrations were found to be associated with hyponatremia and were progressively elevated in patients who eventually developed delayed ischemic deficit secondary to vasospasm. The purpose of the present study was to evaluate trends in BNP plasma concentrations during the acute phase following severe (traumatic brain injury) TBI...

OBJECTIVE: The role of hypertension as a major risk factor for the development and rupture of cerebral aneurysms is a subject of considerable debate. METHODS: In order to substantiate or weaken the hypothesis of the atherogenic, degenerative origin of this disease, in addition to hypertension the influence of smoking and the covariates body weight, hematocrit, fibrinogen and leukocrit were examined in a hospital-based case-control and cohort study. 141 consecutive patients with subarachnoid hemorrhage (SAH) and verified cerebral aneurysms, admitted between September 1994 and August 1998, were investigated...

Cerebral aneurysm may occur in some cases of major cerebral artery occlusion. However, according to our search of the literature, only four cases of aneurysmal subarchnoid hemorrhage (SAH) associated with bilateral common carotid artery occlusion (CCAO) have been reported in addition to the case we report here with a summary of the previously reported cases. A healthy 82-year-old female was found unconscious and admitted to our hospital where her neurological state was diagnosed as Hunt & Kosnik grade II, World Federation of Neurosurgical Societies grade II...

Two macerated fetuses in utero are presented. The mothers experienced no abnormalities during pregnancy. Both fetuses were found postmortem to have intracranial angiomas. In case 1, the angioma in the choroid plexus of the right lateral ventricle was associated with intraventricular and subarchnoid hemorrhages. There was additional angiomatosis in the leptomeninges and substance of the brain. In case 2, there was leptomeningeal angiomatosis with diffuse subarchnoid hemorrhage. It is suggested that spontaneous rupture of the angioma of the choroid plexus in case 1 and of the leptomeninges in case 2 resulted in immediate death of the fetuses with subsequent maceration in utero...
