Arteriovenous malformations represent a unique challenge to the facial plastic and reconstructive surgeon. Unlike other vascular anomalies, such as hemangiomas or capillary vascular malformations (or port-wine stains), true arteriovenous malformations are rare aberrations in vascular morphogenesis. Their rarity and high propensity toward bleeding and recurrence combined with the potential for life-threatening rupture may make the occasional surgeon who dares to resect these lesions rightfully less than intrepid in his endeavor.

Eloquent brain creates a challenge when resecting brain arteriovenous malformations (bAVMs). Here the authors present their technique of using subcortical motor mapping as an adjunct to increase safety during resection of a high-grade bAVM involving somatosensory cortex as well as cortical spinal tracts and visual tracts. After a bilateral craniotomy, they use direct cortical stimulation of the left motor cortex and subcortical stimulation using a suction stimulator to dynamically map motor tracts during the resection.

Introduction: Brain arteriovenous malformations (AVM) are complex vascular pathologies with a significant risk of hemorrhage. Stereotactic radiosurgery (SRS) is an effective treatment modality for AVM, initially popularized on the Gamma Knife (Elekta AB, Stockholm, Sweden) platform, and now benefits from the modern advances in linear accelerator (LINAC)-based platforms. This study evaluates the outcomes of LINAC-based SRS/hypofractionated stereotactic radiotherapy (hFSRT) for cerebral AVMs.

Cerebral proliferative angiopathy (CPA) is a rare subtype of cerebral arteriovenous malformation, characterized by unique angiographic features and clinical presentations. Although the clinical and angiographic characteristics of CPA have been well described, their impact on the surrounding tissues remains underexplored. Herein, we investigated the presence of calvarial thickening in patients with CPA, and discuss its potential pathogenesis.

Rationale: Temporary central venous catheters are commonly used for patients who require emergency hemodialysis. In rare instances, this procedure can result in a very serious complication known as arteriovenous fistula (AVF). Although some cases of femoral arteriovenous fistula have been reported previously in the literature; however, the incidence of iliac AVF precipitated by a hemodialysis catheter is exceedingly uncommon.

Hereditary haemorrhagic telangiectasia (HHT) is a rare genetic disease characterised by mucocutaneous telangiectasias and arteriovenous malformations that can affect multiple organs. Although rare, ischaemic cholangiopathy can occur, a serious complication that can even lead to death. We present the case of a patient with HHT disease with previous mucocutaneous and gastrointestinal manifestations in whom 8 weeks after cholecystectomy a saccular dilatation of the intrahepatic bile duct was observed.
