Brain noncontrast computed tomography (CT), CT angiography, and magnetic resonance imaging have been used clinically for decades, and emergency physicians have a good understanding of their indications, the meaning of their results, and some facility with the interpretation of CT. However, brain CT perfusion (CTP) is relatively new and emergency physicians are less familiar with its basic concepts, indications, and role in managing patients with neurological emergencies. ⋯ Taking care of patients with large-vessel occlusions is multidisciplinary, and emergency physicians need to understand CTP imaging and its clinical utility.

Multicenter Study Comparative Study
Prospective Evaluation of a Fixed-Dose 4-Factor Prothrombin Complex Concentrate Protocol for Urgent Vitamin K Antagonist Reversal.
Four-factor prothrombin complex concentrate (4F-PCC) is the standard of care for reversal of vitamin K antagonists (VKAs). Research has demonstrated noninferior efficacy with the use of lower, fixed-dose strategies for 4F-PCC dosing. ⋯ The use of a fixed-dose 4F-PCC protocol is safe and effective for the rapid reversal of VKA-associated anticoagulation.

Physical violence against women is a major public health problem in African countries; however, no studies have focused on factors associated with violent injuries to women in Africa. ⋯ Most risk factors identified for violent injury among African women are unique to the studied geography. Violence prevention programs, if designed based on these identified risk factors, may be more effective for this population.

Renal arteriovenous malformation (AVM) is a rare cause of massive hematuria, and patients with renal AVM may present with symptoms like urinary tract infections in the emergency department. ⋯ A 37-year-old woman presented to the emergency department with symptoms of hematuria, urinary hesitancy, and severe suprapubic pain that had been present for a few hours. A urine examination revealed no pyuria, but urine occult blood for 3+ and a red blood cell count of >100 per high-power field. Bedside echocardiography revealed right kidney hydronephrosis and a distended bladder with a blood clot. A 3-way Foley catheter was inserted and drained 800 mL of bloody urine. A contrast-enhanced computed tomography scan was ordered that showed a 1.1-cm hypervascular tumor in the lower pole of right kidney, with active bleeding and rupture into the adjacent collecting system. Active renal tumor bleeding or renal AVM was suspected. The patient was transferred to a tertiary medical center where right renal artery angiography was arranged and disclosed an AVM with aneurysm formation at the right renal lower pole. Transarterial embolization was performed immediately to embolize the 3 feeders of the AVM. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Renal AVM is a rare but potentially life-threatening cause of massive hematuria. Delayed or missed diagnosis is possible because renal AVM may present with symptoms like urinary tract infection, especially in young females. Renal artery angiography is the diagnosis of choice, and emergent transarterial embolization is now the standard of treatment.
