1. Intrasaccular flow disruption (WEB) of a large wide-necked basilar apex aneurysm using PulseRider-assistance

Abstract

Large, wide-necked basilar apex aneurysms are difficult to treat. Microsurgical clipping can result in neurologic morbidity and mortality. Endovascular treatment often leaves remnants that need retreatment and/or stent placement with dual antiplatelet therapy. The Woven EndoBridge (WEB) is an intrasaccular flow disruption device that can be used without dual antiplatelet therapy. However, the WEB cannot typically be used in large or giant aneurysms > 10 mm because the largest diameter device is the 11 × 9.6 mm single layer sphere (SLS). We present a case in which we use a PulseRider aneurysm neck reconstruction device in the basilar artery to assist in WEB deployment within a 22 mm basilar apex aneurysm with 14 mm neck, thereby permitting aspirin monotherapy postoperatively.

2. Intracranial hemorrhage due to central venous occlusion from hemodialysis access: A case report

Abstract

Central venous stenosis in hemodialysis patients rarely causes venous hypertension and intracranial hemorrhage. A 54 year-old male with right arm arteriovenous fistula was transferred to our institution in a comatose state following right parietal venous infarction. Fistulography showed right brachiocephalic vein (BCV) occlusion with reflux into the right transverse sinus and obstruction of left internal jugular vein outflow due to the styloid process. Balloon venoplasty of the right BCV occlusion failed to improve the patient’s status because of the delayed diagnosis. Headaches and neurologic symptoms in hemodialysis patients can herald intracranial hypertension due to central venous occlusion and needs prompt assessment with fistulography.

3. Neurofibromatosis-associated massive right internal carotid artery aneurysm with a coexisting arteriovenous fistula

Abstract

A 47-year-old woman presented with a right cervical mass that had been slowly enlarging for 6 years, causing pulsatile tinnitus and dizziness with compression. Computed tomography angiography demonstrated a partially thrombosed 8-cm right internal carotid artery aneurysm with a coexisting arteriovenous fistula. Conventional angiography demonstrated a vertebrojugular fistula (right vertebral artery to right internal jugular vein) and retrograde flow in the right vertebral artery to the fistula. Successful repair was performed in a staged fashion: operative repair of the internal carotid artery aneurysm with interposition bypass, followed by endovascular embolization of the vertebrojugular fistula through a bilateral vertebral artery approach.

4. Endovascular biopsy: Strategy for analyzing gene expression profiles of individual endothelial cells obtained from human vessels

Abstract

Purpose: To develop a strategy of achieving targeted collection of endothelial cells (ECs) by endovascular methods and analyzing the gene expression profiles of collected single ECs. Methods and results: 134 ECs and 37 leukocytes were collected from four patients' intra-iliac artery endovascular guide wires by fluorescence activated cell sorting (FACS) and analyzed by single-cell quantitative RT-PCR for expression profile of 48 genes. Compared to CD45+ leukocytes, the ECs expressed higher levels (p

Abstract

As a refresher course on current techniques and practice of cerebral angiography, this chapter outlines the steps in effective angiography, incorporating modern quality and safety considerations. The format is step-by-step from preprocedure to intraprocedure to postprocedure for ease of reference. The chapter will serve as a framework for the fledgling angiographer, augmenting the important teaching provided by a seasoned angiographer.

6. Vascular anomalies: Classification and management

Abstract

Vascular anomalies are broadly classified into two major categories: vascular tumors and vascular malformations. Most vascular anomalies are caused by sporadic mosaic gene mutations, and recent genetic studies have advanced our understanding of the molecular pathways involved in their pathogenesis. These findings have suggested new therapeutic approaches to vascular anomalies, focusing on their pathogenetic mechanism. This chapter seeks to integrate an improved molecular understanding within the updated classification system of the International Society for Study of Vascular Anomalies. We emphasize the genetic, radiologic, and interventional aspects of diagnosis and management in hopes of allowing improved multidisciplinary collaboration surrounding these complex and interesting anomalies.

Abstract

Neurologic complications of imaging procedures are varied and largely related to either local complications of an invasive procedure or complications arising from the systemic use of intravenous contrast agents. This chapter provides a summary of neurologic complications related to those imaging procedures that are commonly performed in modern radiologic practices. Some historical perspective is presented as well, and the reader must be aware that changes in the practice of radiologic procedures affect the kinds of complications and their incidence over time.
