We report the first case of a young patient who presented with the features of Horner's syndrome following a spinal extradural hematoma resulting from a ruptured arterio-venous malformation (AVM). Since there were features of early compressive myelopathy as well, urgent magnetic resonance imaging (MRI) scan of the spine revealed features suggestive of an extradural hematoma in the cervico-thoracic junction. The patient underwent an emergent laminectomy with an evacuation of the hematoma. The histological features were consistent with that of an AVM...

Pulmonary arteriovenous malformations (PAVMs) are atypical vascular structures involving a direct connection between the pulmonary arterial and venous circulations. While PAVMs are a relatively uncommon disorder, unmanaged cases are at risk for the development of serious complications including embolization and infection. Since their first description in 1897, PAVMs have been identified and treated in a variety of ways. Advancements in diagnostic methods and operative techniques have allowed for more effective treatment of the disease...

INTRODUCTION: The current state-of-the-art treatment modality for hypertrophic capillary malformations (CMs), laser therapy, has a considerable rate of non-responders and recurrence. Intralesional bleomycin injections (or 'sclerotherapy') are commonly used to treat venous and lymphatic malformations with an excellent effect, but these intravascular injections are not possible in CMs due to the small diameter of the vessels. Electroporation-an electric field applied to the tissue-could increase the permeability of endothelial cells, which could theoretically facilitate targeted localised bleomycin delivery...

Intracranial dural arteriovenous fistulae (DAVF) are complex vascular malformations consisting of a pathological shunt located between meningeal arteries and drainage to dural venous sinuses and/or cerebral veins. We report an unusual anatomical variation, resulting in a DAVF forming between the superior sagittal sinus and an anomalous origin of the middle meningeal artery (MMA) arising from the left ophthalmic artery. We present an atypical case requiring mini-craniotomy for catheter access, as well as cannulation of extracranial arterial supply prior to embolization of a Cognard type IIa+b fistula...

RATIONALE: Brain arteriovenous malformations (AVMs) are congenital vascular abnormalities involving abnormal connections between arteries and veins. In clinical practice, imaging studies help evaluate feeding arteries, niduses, draining venous systems, and coexisting complications in patients with brain AVM. They also have an impact on decision-making regarding clinical management. We applied a novel non-contrast-enhanced MR angiography (MRA) technique, termed "silent MRA," for evaluating an incidental brain AVM...

Developmental venous anomalies are cerebral vascular malformations that present normal venous drainage of cerebral tissue. With increased and accessible usage of modern diagnostic tools, they are now one of the most commonly diagnosed cerebral vascular malformations. Although developmental venous anomalies are considered to be benign lesions, association with arteriovenous malformation renders malignant potential to this combined pathology. In the case presented, these malformations were clinically silent and diagnosed accidentally, so they were not treated either with surgery, endovascular surgery or radiosurgery, considering the possible complications such as venous infarction of the brain, and because there was no obvious neurologic deficit related to this pathology...

Spinal dural arteriovenous fistulas are produced by direct communication between the arterial and venous systems of the spinal cord, causing hypertension in the latter with spinal cord dysfunction. It is a rare pathology with unknown etiology and non-specific clinical symptoms that usually results in a delayed diagnosis. Often radiologists are the first to guide the disease towards an adequate diagnosis. Characteristic findings can be seen through MR or MR angiography, and may even locate the fistula in a high percentage of cases, although the pathology must be confirmed by spinal angiography...

Several periorbital lesions can be clinically misdiagnosed as dermoid cyst. We retrospectively reviewed the histopathological findings for 97 biopsied periorbital lesions with a clinical diagnosis of dermoid cyst from January 2006 to July 2016 at a single center and identified 5 cases that were eventually found to have been misdiagnosed. The main presenting symptom was a long-standing mobile painless mass with intact overlying skin below the medial aspect of the brow in 4 patients and below the center of the brow in 1 patient...

BACKGROUND: Digital subtraction angiography (DSA) currently provides angioarchitectural features of cerebral arteriovenous malformations (AVMs) but its role in the hemodynamic evaluation of AVMs is poorly understood. OBJECTIVE: To assess contrast time-density time (TT) on DSA relative to AVM flow measured using quantitative magnetic resonance angiography (QMRA). METHODS: Patients seen at our institution between 2007 and 2014 with a supratentorial AVM and DSA and QMRA obtained prior to any treatment were retrospectively reviewed...

REVIEW
Zhi Gao, Yi Zhang, Wei Li, Chen Shi
A meta-analysis was conducted to investigate the efficacy and safety of polidocanol versus other conventional therapies in treating hemangiomas (HMs) and vascular malformations (VMs). Literature search was conducted in the Cochrane, Embase, PubMed, Web of Science, CNKI, CBM, VIP, and WanFang databases until March 5, 2017. A meta-analysis was conducted using Revman 5.3 software. A total of 19 randomized controlled trials (RCTs) involving 1,514 participants met the inclusion criteria. Regarding the effectiveness, statistically significant differences were observed between polidocanol and all the independent treatments (p = ...

AIM: To evaluate clinical and imaging outcomes after ultrasound (US)-guided 3% polidocanol (POL) foam-sclerotherapy of venous malformations (VMs). METHODS: We retrospectively evaluated consecutive VM cases over 1.5 years, with 6-month follow-up. US findings were used to classify VMs into four types depending upon extent of anechoic channels, connections to adjacent veins, and dysmorphism. Single or multiple needles were inserted depending upon lesion size, and used to inject up to 8 mL POL per session, every 2 to 4 weeks...

BACKGROUND: Antiepileptic treatment strategy plays an important role in the management of intracranial vascular malformations. The intracranial vascular malformations can be divided into cavernous hemangiomas, arteriovenous malformations, developmental venous anomalies and capillary telangiectasias. Seizures and hemorrhage are among their most common clinical manifestations. OBJECTIVE: The aim of this article is to review the current literature on the antiepileptic treatment in the setting of intracranial vascular malformations and offer an updated view on when antiepileptic drug treatment should be employed for each type of vascular malformation...

INTRODUCTION: Pulmonary arteriovenous malformations (PAVMs) may not be amenable to treatment by embolisation or surgical resection, and many patients are left with significant hypoxaemia. Lung transplantation has been undertaken. There is no guidance on selection criteria. METHODS: To guide transplantation listing assessments, the outcomes of the six patients who had been considered for transplantation were compared with a similarly hypoxaemic patient group recruited prospectively between 2005 and 2016 at the same UK institution...

BACKGROUND AND AIMS: Until now, no study has focused exclusively on low-flow retrobulbar intraconal venous malformations (RIVMs) which may require treatment due to cosmetic defect, pain, and visual dysfunction. The treatment for RIVMs which surround the optic nerve remains challenging. This case series aimed to evaluate the technical feasibility, effectiveness, and safety of percutaneous sclerotherapy with polidocanol for low-flow RIVMs, using local anesthesia. METHOD: This is a prospective, non-comparative, single-center, interventional case series...

Venous malformations are congenital anomalies of the vascular system. The injection of bleomycin (a cytotoxic, antitumour drug) into the lesion is a safe and effective treatment for low-flow (venous and lymphatic) malformations, but its use systemically has been associated with pulmonary fibrosis. Intralesional injection of bleomycin is considered to have a lower risk, but caution should be used when planning treatment, with particular regard to respiratory function. Electroporation is the temporary application of an electrical field across a tissue to increase (briefly) the permeability of the cell membrane in that tissue...
