- Carotid Near-Occlusion: A Comprehensive Review, Part 2—Prognosis and Treatment, Pathophysiology, Confusions, and Areas for Improvement
Carotid near-occlusion is distal luminal collapse of the internal carotid artery beyond a tight stenosis. Part 2 of this systematic review focuses on prognosis and treatment and pathophysiology. Areas of confusion regarding terminology, diagnosis, and prognosis are also covered.
- Treatment of 213 Patients with Symptomatic Tarlov Cysts by CT-Guided Percutaneous Injection of Fibrin Sealant
This cohort study assesses outcomes in patients who underwent CT-guided aspiration and injection of sacral Tarlov cysts at Johns Hopkins Hospital from 2003–2013. A total of 289 cysts were treated in 213 consecutive patients, with 83% followed for 3–6 years. One year postprocedure, excellent results were obtained in 104 patients (54.2% of patients followed), and good or satisfactory results were obtained in 53 patients (27.6%).
- MR Angiographic–Guided Percutaneous Sclerotherapy for Venous Vascular Malformations: A Radiation Dose-Reduction Strategy
This case series of 5 patients describes the authors' approach to using dynamic MRA with direct puncture of venous malformations to define the angioarchitecture and draining veins in these lesions. MultiHance in a 1:100 dilution with normal saline solution was used for the contrast administration. Precontrast images were used as a mask and were digitally subtracted from the postcontrast images (13- and 51-second acquisitions, respectively). The authors conclude that they have developed a method to completely eliminate digital subtraction angiography x-ray radiation exposure during treatment of venous vascular malformations.
