CT-guided cryoablation for palliation of secondary trigeminal neuralgia from head and neck malignancy.

Background: Facial pain is a common presentation secondary to tumoral invasion, rendering an individual unable to perform basic activities such as eating and talking. Cryotherapy may be appropriate in patients seeking immediate pain relief for trigeminal neuralgia (TN) near the end of life with its minimal invasiveness and procedural morbidity. While cryosurgery has been effectively demonstrated in the treatment of primary TN, this study is unique as it is the first documented use of CT guidance and treatment of secondary TN using percutaneous cryoablation.

Endovascular treatment of fusiform intracranial aneurysms.

Background And Purpose: Endovascular treatment (EVT) has emerged as an alternative therapeutic strategy for the treatment of intracranial fusiform aneurysms (IFAs), but little is known about the safety and efficacy of deconstructive and reconstructive methods, especially in patients presenting with subarachnoid hemorrhage (SAH). The purpose of this study is to describe the radiological and clinical outcomes in patients with IFAs undergoing EVT.

Methods: A retrospective analysis was conducted of 18 patients undergoing EVT of IFAs, 13 of whom (72.

Low-flow vascular malformations of the head and neck: clinicopathology and image guided therapy.

Low-flow vascular malformations are congenital lesions secondary to errors in the development of veins, capillaries or lymphatics. The majority of these lesions are sporadic although association with heritable syndromes does occur. Patients with these lesions should be treated and evaluated by a multidisciplinary team comprising medical, radiologic and surgical subspecialties.
