Authors: Wali Y, Kini V, Yassin MA Abstract Background/Objective: Stroke is a potentially fatal complication of sickle cell disease (SCD). Transcranial Doppler (TCD) is useful at identifying increased risk of stroke in children with SCD and vasospasm after subarachnoid hemorrhage. The main aim of this study was to determine the proportion of patients with SCD in the Gulf region who are at a high risk of stroke, as determined by TCD.Methods: This multicenter (Oman, Qatar, and UAE), descriptive, cross-sectional study in patients (aged 2-16 years) with SCD included a baseline visit, 1 follow-up visit for patients with...

Conclusion: There is a wide heterogeneity of postoperative cerebral hemodynamic findings among TBI patients who underwent DC, including hemodynamic heterogeneity between their cerebral hemispheres. DC was proved to be effective for the treatment of cerebral oligoemia. Our data support the concept of heterogeneous nature of the pathophysiology of the TBI and suggest that DC as the sole treatment modality is insufficient. Introduction Decompressive craniectomy (DC) may effectively decrease intracranial pressure (ICP) and increase cerebral perfusion pressure (CPP) in traumatic brain injury (TBI) patients with refracto...

Conclusion: In ischemic stroke or TIA patients with platelet count within normal range, platelet count may be a qualified predictor for long-term recurrent stroke, mortality, and poor functional outcome. Introduction Platelets exert a critical role in the pathogenesis of atherosclerotic complications of cardio-cerebrovascular disease, contributing to thrombus formation, and embolism (1, 2). Previous literature reported that platelets of various size and density are produced by megakaryocytes of different size and stages of maturation in different clinical conditions, suggesting various platelet patterns in differen...

ConclusionsThis analysis of nationally representative US data suggests that although readmission after RS for MMD is not uncommon, cerebral hemorrhagic events during the 90-day postoperative period are rare.

We describe the case of an 18-year-old female affected by HbSS genotype SCD presenting with reversible cerebral vasoconstriction syndrome (RCVS) as well as features of posterior reversible encephalopathy syndrome and convexity subarachnoid hemorrhage (SAH) after transfusion of red blood cells. We reviewed the existing literature dealing with SCD, blood transfusion, and hemorrhagic strokes. To our knowledge, this case presentation is unique with convexity SAH predominantly attributable to a RCVS spectrum disorder occurring in the setting of a recent blood transfusion in an adolescent female with SCD. As this case illustrate...

A 15-year-old boy with sickle cell disease became unresponsive after sudden-onset headache. There was no antecedent trauma. A head CT scan demonstrated subarachnoid hemorrhage at the medulla (figure). Magnetic resonance angiography of the head and neck identified the patient's known bilateral internal carotid artery stenosis (a moyamoya-like arteriopathy associated with stroke in sickle cell disease) and a new right vertebral artery dissection, which was confirmed on conventional angiography (figure). Prior MRI performed as part of routine cerebral monitoring did not reveal any preexisting abnormality of the vertebral artery.

Conclusions— Intracranial aneurysms are common in HbSS SCD. There was also a trend toward more common occurrence of aneurysmal subarachnoid hemorrhage in HbSS; women in the age group 30 to 39 years were most at risk. There was no correlation between the occurrence of intracranial aneurysms and moyamoya syndrome.

Objective: To identify differences between patients with isolated subarachnoid hemorrhage (SAH) vs SAH and sickle cell disease (SCD). Introduction: Neurological complications of SCD occur in 1/3 of cases. Ischemic strokes are the most common complication (75[percnt]), followed by intracerebral hemorrhage (20[percnt]). SAH is rare. There are several case reports of patients with SCD and SAH. However, no studies have described the frequency of SAH related to SCD among all patients with SAH. We sought to compare the demographics of SAH in SCD versus non-SCD patients. Methods: We searched the 2005-2010 Nationwide Inpatient Sam...

OBJECTIVE: To review the stroke epidemiological data, etiology and mortality rates in young adults of UAE. BACKGROUND: Stroke is a serious cause of long-term disability. The risk of having a stroke varies with age, race and ethnicity. In view of limited studies of stroke in the Middle East, especially in young age adults, it is important to highlight the rates of occurrence, etiological and risk factors, as well as mortality rates. METHODS: In the last 4 years, we retrospectively reviewed the medical records of all patients admitted with stroke. Only patients (aged 18-40 y) with a confirmed diagnosis of first ever stroke o...
