Pulmonary arteriovenous malformations: diagnosis.

Cardiovasc Diagn Ther 2018 Jun;8(3):325-337

Department of Radiology, UT Southwestern Medical Center, Dallas, Texas, USA.

Pulmonary arteriovenous malformations (PAVMs) are rare, abnormal low resistance vascular structures that connect a pulmonary artery to a pulmonary vein, thereby bypassing the normal pulmonary capillary bed and resulting in an intrapulmonary right-to-left shunt. The spectrum of PAVMs extends from microscopic lesions causing profound hypoxemia and ground glass appearance on computed tomography (CT) but with normal catheter angiographic findings to classic pulmonary aneurysmal connections that abnormally connect pulmonary veins and arteries. These malformations most commonly are seen in hereditary hemorrhagic telangiectasia (HHT). Read More

Endoscopic Transnasal Transclival Approach to a Pontine Cavernoma with Associated Developmental Venous Anomaly.

World Neurosurg 2018 Oct 18;118:212-218. Epub 2018 Jul 18.

Department of Neurological Surgery, George Washington University, Washington, DC, USA.

Background: Brainstem cavernous malformations represent around 8%-22% of all intracranial cavernous malformations but exhibit a higher annual incidence of hemorrhage (2%-3%) compared with other cavernous angiomas and tend to be more symptomatic given their proximity to critical nuclei and fiber tracts. Recently, endoscopic endonasal techniques have been used for the removal of ventral skull base lesions, with significant improvement in operative morbidity and mortality compared with open approaches. Here we demonstrate the utility and feasibility of the endoscopic transclival approach for ventrally located pontine cavernomas in carefully selected patients. Read More

Giant arachnoid granulation with a thrombosed dural arteriovenous fistula.

BMJ Case Rep 2018 Jun 27;2018. Epub 2018 Jun 27.

Radiodiagnosis, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, India.

Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously reported to cause venous hypertension and headaches. We report a case of GAG involving the proximal half of the superior sagittal sinus in a 45-year-old male patient which was associated with left temporal thrombosed dural arteriovenous fistula (AVF) whose thrombosed draining veins were seen converging towards the site of GAG.

Arterial spin labeling MR imaging aids to identify cortical venous drainage of dural arteriovenous fistulas.

Medicine (Baltimore) 2018 May;97(19):e0697

Institute of Radiation Medicine, Seoul National University Medical Research Center.

Cortical venous drainage (CVD) increases the probability of intracranial hemorrhage and mortality rate of dural arteriovenous fistulas (DAVF). Although digital subtraction angiography (DSA) is the most accurate method to determine CVD in DAVFs, this modality has limitations due to its invasive nature and radiation issues. The purpose of this study was to evaluate the diagnostic utility of arterial spin-labeling perfusion-weighted images (ASL-PWI) to identify CVD in patients with DAVF. Read More

Intracranial hemorrhage in neonates: A review of etiologies, patterns and predicted clinical outcomes.

Eur J Paediatr Neurol 2018 Jul 24;22(4):690-717. Epub 2018 Apr 24.

Department of Radiology, Great Ormond Street Hospital NHS Foundation Trust, Great Ormond St, London WC1N 3JH, UK. Electronic address:

Intracranial hemorrhage (ICH) in neonates often results in devastating neurodevelopmental outcomes as the neonatal period is a critical window for brain development. The neurodevelopmental outcomes in neonates with ICH are determined by the maturity of the brain, the location and extent of the hemorrhage, the specific underlying etiology and the presence of other concomitant disorders. Neonatal ICH may result from various inherited and acquired disorders. Read More

Three-dimensional angioarchitecture and microsurgical treatment of arteriovenous fistulas at the craniocervical junction.

J Clin Neurosci 2018 Jul 3;53:140-146. Epub 2018 May 3.

Department of Neurosurgery, The University of Tokyo Hospital, 7-3-1, Hongo, Bunkyo-ku, Tokyo 113-8655, Japan.

Digital subtraction angiography (DSA) is the gold standard for diagnosing vascular malformations; however, difficulties are associated with visualizing the angioarchitecture of arteriovenous fistulas at the craniocervical junction (CCJ AVFs) using DSA because of their complex regional neurovascular anatomy. The present study evaluated the application of 3-dimensional computer graphics (3D CG) to the surgical planning of CCJ AVFs. Six patients with CCJ AVFs who underwent microsurgery and/or endovascular treatment were included. Read More

May the Inferior Petrosal Sinus Recanalization During Endovascular Treatment for Carotid-Cavernous Fistulas Increase the Risk of Sixth Nerve Palsy?

World Neurosurg 2018 Aug 3;116:e246-e251. Epub 2018 May 3.

Department of Interventional Neuroradiology, Rothschild Foundation Hospital, Paris, France.

Background: Sixth nerve palsy is a common complication of endovascular treatment for carotid-cavernous fistulas (CCF). Two hypotheses are evoked: the spontaneous venous congestion into the cavernous sinus and the direct compression of the nerve by the embolic agent into the cavernous sinus. Nevertheless, the evidence is still uncertain. Read More

Almost all primary hemifacial spasms are associated with one or more neurovascular conflicts, most often at the root exit zone in the immediate vicinity of the brainstem. Imaging has first to exclude a secondary hemifacial spasm and secondly to search for and characterize the responsible neurovascular conflict(s). Magnetic resonance imaging should include high-resolution anatomical hyper T2-weighted sequences and magnetic resonance angiography by using 1. Read More

Embolization of a cavernous carotid fistula through the vein of Labbé: a new alternative transvenous access route.

J Neurointerv Surg 2018 Jun 7;10(6):e11. Epub 2018 Apr 7.

Department of Neurosurgery, Huntington Memorial Hospital, Pasadena, California, USA.

Endovascular treatment of carotid cavernous fistulas (CCFs) via a transvenous approach is standard, but in rare cases this approach is challenging due to absence or thrombosis of the commonly used venous routes. A 61-year-old woman presented with a symptomatic CCF with all but one of the venous access routes to the CCF thrombosed, leaving an engorged superficial middle cerebral vein (SMCV) as the only venous outflow from the cavernous sinus. Access to the CCF was made possible after careful navigation of the sigmoid sinus, the vein of Labbé and the SMCV, bypassing the need for surgical access to the SMCV or for a direct transorbital puncture.

An overlooked cause in a patient with recurrent ischemic stroke: A case report.

Medicine (Baltimore) 2018 Mar;97(13):e0146

Department of Neurology.

Rationale: The majority of ischemic strokes are due to cardioembolism, large vessel atherothromboembolism, small vessel occlusive disease, or other unusual mechanisms. In most clinical settings, many strokes without a well-defined etiology requires a thorough diagnostic evaluation, otherwise the underlying cause might be easily overlooked. Here we report on the rare cause of a patient with recurrent stroke. Read More

J Neurosurg Sci 2018 Aug 26;62(4):478-483. Epub 2018 Mar 26.

Department of Neurosurgery, Huashan Hospital, Shanghai Medical College, Fudan University, Shanghai, China -

Because of the more frequent use of noninvasive imaging methods, arteriovenous malformation (AVM) are gaining more attention. Population based studies reveal that about 35% to 50% of patients with AVM initially present with hemorrhage. Prior hemorrhage is the most consistent risk factor for future hemorrhage, other risk factors include deep venous drainage pattern, deep location, and so on. Read More

Lessons to Be Remembered from a Dural Arteriovenous Fistula Mimicking Medulla and High Cervical Cord Glioma.

World Neurosurg 2018 May 7;113:312-315. Epub 2018 Mar 7.

Department of Neurosurgery, Teaching Hospital, Angers, France.

The radiological signs of intracranial dural arteriovenous fistulas (ICDAVFs) are heterogenous. While it is commonly accepted that hyper intense T2 wedge magnetic resonance imaging of the brainstem and cervical cord mainly concern gliomas, it is so far uncommon and probably unknown that ICDAVFs can imitate similar radiological pattern, especially with gadolinium contrast enhancement and cord enlargement. Thus the angiography is poorly documented in the diagnostic workup. Read More

Transient Ischemic Attack while Injecting Intravenous Saline Contrast in a Patient with Persistent Left Superior Vena Cava.

J Stroke Cerebrovasc Dis 2018 Jul 2;27(7):e119-e120. Epub 2018 Mar 2.

Department of Neurology, Cruces University Hospital, Barakaldo, Spain.

In this case report, we describe a patient who has a persistent left superior vena cava (PLSVC) manifesting as a transient ischemic attack (TIA) and a remote brain abscess. PLSCV, when draining in the left atrium, is a cause of right to left shunt, and it has been related to brain abscesses and, as reported in a few cases, to ischemic stroke. After admission, our patient experienced 2 new episodes of TIA while being injected with agitated saline contrast through the left arm, producing echocardiographic images of right to left shunt, which gave the clue to the diagnosis.
