CIRCULATION. Anticoagulation With the Oral Direct Thrombin Inhibitor Dabigatran Does Not Enlarge Hematoma Volume in Experimental Intracerebral Hemorrhage

Background—The direct thrombin inhibitor dabigatran etexilate (DE) may constitute a future replacement of vitamin K antagonists for long-term anticoagulation. Whereas warfarin pretreatment is associated with greater hematoma expansion after intracerebral hemorrhage (ICH), it remains unclear what effect direct thrombin inhibitors would have. Using different experimental models of ICH, this study compared hematoma volume among DE-treated mice, warfarin-treated mice, and controls.

CVIR. Posttraumatic Basilar Artery Herniation Associated with Dissecting Aneurysm Formation: Follow-up Over 20 Months

Jingqin Fang, Lianqin Kuang, Jinhua Chen, Yi Wang, Rong Chen, Kunlin Xiong, Weiguo Zhang

Introduction The fracture in the clivus of occipital bone, which might be longitudinal, transverse, or oblique, accounts for 0.36–0.57% of traumatic brain injuries found by computed tomography (CT) [1, 2]. Among these, the longitudinal clivus fracture has the highest mortality rate as a result of the direct injury of brain stem and vertebrobasilar artery [1–3]. Longitudinal clival fracture with the incarceration of vertebrobasilar artery at the fracture site is unusual. Only 15 cases had been reported previously [3, 4–15], and 10 patients died [3, 4, 6–11].

JACC CARDIOVASCULAR INTERVENTIONS. Carotid Artery Stenting Before Cardiac Surgery. A Promising Path Down a Muddy Road?

William Anthony Gray, MD

The management of synchronous carotid disease and coronary or valvular disease requiring surgical repair has been a constant challenge to clinicians for decades and for a variety of reasons. First, although it is a vexing problem, it is relatively infrequent, such that any single institution/operator experience in management will always be clouded by “the last case I did” syndrome, more reflective than definitive. Second, even in patients without carotid stenosis, the risk of stroke inherent in cardiac surgery from other sources (atheroembolic from aortic manipulation, air emboli, and so on) clouds the assessment of the neurological “natural” history of the unoperated carotid stenosis in this setting. However, it seems clear enough that the patient with symptomatic carotid disease is at most risk and requires further management consideration, but that most asymptomatic patients with unilateral disease can withstand a cardiac operation with little increase in overall stroke risk and, therefore, should not be subjected to carotid revascularization risks (2). Next, the published database that generally helps guide such decisions in practice comprises largely single-center reports, and usually retrospectively analyzed.

CIRCULATION. Cerebral Abscess Due to Persistent Left Superior Vena Cava Draining Into the Left Atrium

Ming-Sum Lee, MD, PhD; Reena L. Pande, MD; Balaji Rao, MD; Michael J. Landzberg, MD; Raymond Y. Kwong, MD

A 47-year-old woman with a history of paroxysmal atrial fibrillation presented with seizure. She noted progressive fatigue in the preceding 6 months. The week before admission, she had worsening headaches and increased irritability. On the day of admission, she developed an episode of grand-mal seizure. MRI of the brain revealed a round lesion in the left frontal lobe measuring 11 cm by 15 mm with an extensive halo of T2 hyperintensity surrounding the lesion and minimal inherent T1 high signal along the border. The lesion was suspicious for an abscess. She was taken to the operating room for biopsy. Craniotomy and corticectomy revealed an abscess cavity with a large amount of purulent material. Culture of the purulent drainage grew Streptococcus intermedius. She was started on penicillin G and metronidazole. Circulation. 2011; 124: 2362-2364 doi: 10.1161/​CIRCULATIONAHA.111.046102.
