Transoesophageal echocardiography prior to catheter ablation could be avoided in atrial fibrillation patients with a low risk of stroke and without filling defects in the late-phase MDCT scan: A retrospective analysis of 783 patients
ConclusionsFor AF patients with low risk of stroke, when MDCT images showed no filling defect in the late phase, TEE prior to catheter ablation can be avoided.Key Points•MDCT can help detect the presence of LAA thrombus.•TEE can be avoided when late-phase MDCT shows no filling defect.•TEE is required in patients whose MDCT images indicate thrombus.

Severe Symptoms, but a Truly Treatable Disease
​BY NOURA MAHDI; DARRON LEWIS; JEREMY OSBORNE; & AHMED RAZIUDDIN, MDA 73-year-old man was brought to the emergency department from his nursing home for rectal bleeding and anemia. The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2. He also complained of dyspnea but denied any other ...

The “Blush” Sign on Computed Tomography Angiography is an Independent Predictor of Hematoma Progression in Primary Hypertensive Hemorrhage
Hypertension is an important etiology of intracerebral hemorrhage (ICH) in neurosurgical practice. Contrast extravasation on computed tomography angiography, known as the “spot sign”, has been described as an independent predictor of hematoma progression and clinical deterioration. However, its role in hypertensive ICH alone has not been determined and is the primary aim of this study.

Predictor variables of abnormal imaging findings of syncope in the emergency department
ConclusionsOur data offer that the identification of predictor variables has a potential to decrease the routine use of head CT and MRI in patients admitting to the ED with syncope.

Predictors of Thrombolysis Administration in Mild Stroke Clinical Sciences
Conclusions—Mild acutely presenting stroke patients are more likely to receive thrombolysis if they are young, white, or Hispanic and arrive early to the hospital with more severe neurological presentation. Identification of predictors of thrombolysis is important in design of future studies to assess the use of thrombolysis for mild stroke.

Intraoperative cone beam computed tomography-guided endovascular recanalization of an interrupted aorta
We report a case of real-time image-guided endovascular repair to highlight the value of preprocedural planning and intraprocedural cone beam computed tomography. Two-dimensional fluoroscopy enhanced with three-dimensional landmarks from cone beam computed tomography was used to direct a Nykanen radiofrequency wire (Baylis Medical, Montreal, Quebec, Canada) through the interruption, avoiding critical adjacent structures.

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Intracranial Arterial Calcification in Black Africans with Acute Ischaemic Stroke
Conclusions: The burden of IAC is very high among native African patients with AIS and preferentially involves proximal inflow arteries. Therefore, the role of large vessel atherosclerosis in ischaemic stroke in native Africans should be explored in future multinational, multimodality studies.Cerebrovasc Dis Extra 2018;8:26 –38

What is the role of screening for pulmonary hypertension in adults and children with sickle cell disease?
Authors: Willen SM, Gladwin MT Abstract Patient case: An 18-year-old male patient with homozygous hemoglobin SS disease was evaluated for progressive dyspnea and elevated tricuspid regurgitant jet velocity (TRV) on echocardiography. The patient's case is described in detail in Lancet1 He had been treated with regular transfusions since childhood for stroke, had rare episodes of vaso-occlusive pain episodes, and did not take narcotic pain medications. He presented with progressive severe dyspnea on exertion and lower extremity edema. His laboratory tests were notable for a total hemoglobin level of 11.8 g/dL and hem...

Symptomatic and silent cerebral infarction following surgical clipping of unruptured intracranial aneurysms: incidence, risk factors, and clinical outcome
In conclusion, the incidence of CI following clipping of UIAs was not low. Larger aneurysm size and history of hypertension were independent risk factors. Postoperative symptomatic str oke correlated with an extremely high risk of disability. Silent CI was seemingly nondisabling, but the possible cognitive consequence is pending.

Cerebral Arterial Stenosis in Patients with Spontaneous Intracerebral Hemorrhage.
CONCLUSION: 19.2% of patients with spontaneous ICH had ICAS, but the prevalence of ECAS was relatively lower (7.2%) compared with ICAS. Aging and diabetes were independent factors for the presence of ICAS, whereas aging, hypertension, and diabetes were factors for the cerebral arterial stenosis. PMID: 28881113 [PubMed]

Hypertension, Acute Stent Thrombosis, and Paraplegia 6  Months after Thoracic Endovascular Aortic Repair for Blunt Thoracic Aortic Injury in a 22-Year-Old Patient
Thoracic endovascular aortic repair (TEVAR) is a less invasive option for managing traumatic injuries of the descending aorta in polytraumatized patients. Concerns arise when treating young patients with TEVAR. A 22-year-old male was admitted to the emergency department following a high-impact road traffic collision. Whole-body computed tomography (CT) scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke.

Whole body CT scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke. We decided to treat him in an endovascular fashion with a Zenith Cook (Cook Incorporated, Bloomington, IN) endograft.
