Arteriovenous (AV) malformations of the face are rare presentations. Endovascular coiling is one of the treatment modalities. We report a case of a 65-year-old lady who presented with a large AV malformation of the face located around the nasal bride and alae nasae posted for coiling under general anesthesia. Anesthetic management of the case was a challenge as it was an anticipated difficult airway situation. Furthermore, any pressure on the swelling can lead to rupture and hemorrhage as the skin above swelling was unhealthy...

Pulmonary arteriovenous malformation, which is defined as the presence of an ab-normal connection between the pulmonary artery and pulmonary vein, is rarely seen. Although it generally presents as a congenital condition, it may be accompanied by hereditary hemorrhagic telangiectasia. Clinical signs vary according to the amount of shunt in proportion to the number and size of the fistulae. Patients may present with cyanosis and respiratory trouble. If the disease remains untreated, it may result in cardiac failure and ineffective endocarditis, thereby leading to the rupture of the an-eurysmal fistula...

BACKGROUND: Stereotactic radiosurgery (SRS) is a well-established treatment modality for cerebral arterio-venous malformations (AVMs). The main limiting factor in the radiosurgical treatment of AVMs is the volume of the nidus with high-grade lesions often requiring combined treatment to reduce the SRS target volume. To overcome this limitation, we have been using a combined treatment approach consisting of endovascular embolization with ONYX followed by SRS. OBJECTIVE: To evaluate our clinical experience for safety and feasibility of this multimodality treatment approach...

OBJECTIVE The management of brain arteriovenous malformations (bAVMs) remains controversial. The Treatment of Brain AVMs Study (TOBAS) was designed to manage patients with bAVMs within a clinical research framework. The objective of this study was to study trial feasibility, recruitment rates, patient allocation to the various management groups, and compliance with treatment allocation. METHODS TOBAS combines two randomized care trials (RCTs) and a registry. Designed to be all-inclusive, the study offers randomized allocation of interventional versus conservative management to patients eligible for both options (first RCT), a second RCT testing the role of preembolization as an adjunct to surgery or radiotherapy, and a registry of patients managed using clinical judgment alone...

AVMs are vessel anomalies where a connection between arterial and venous systems is present and the capillary bed is absent between the two. AVMs tend to present with seizures, headaches, focal neurological deficits and hemorrhage. Hemorrhage is the most common form of presentation. AVM's have a 2-4% annual risk of hemorrhage. Certain studies report this rate as 1%. The greatest discussion in AVM treatment is whether to use interventional treatment or monitor with medical treatment. There are 3 modalities that can be used for interventional treatment; microsurgical resection, endovascular embolization and stereotactic radiosurgery...

PURPOSE: Complete obliteration of treated arteriovenous malformations (AVMs) can be diagnosed only by confirming the disappearance of arterio-venous (A-V) shunts with invasive catheter angiography. The authors evaluated whether non-invasive arterial spin labeling (ASL) magnetic resonance (MR) imaging can be used to diagnose the obliteration of AVMs facilitate the diagnosis of AVM obliteration after treatment with stereotactic radiosurgery (SRS). MATERIAL AND METHODS: Seven patients with a cerebral AVM treated by SRS were followed up with ASL images taken with a 3T-MR unit, and received digital subtraction angiography (DSA) after the AVM had disappeared on ASL images...

Pulmonary varix is a rare entity that presents as a focal aneurysmal dilatation of the pulmonary vein and is frequently mistaken for a pulmonary arteriovenous malformation (PAVM). It is important to distinguish between pulmonary varix and PAVM because the former does not usually require treatment. We present the findings of non-contrast-enhanced magnetic resonance angiography with the time-spatial labeling inversion pulse technique in case of pulmonary varix and PAVM and the utility of this method for differentiating between these diseases...
