Endovascular treatment of stent fracture and pseudoaneurysm formation in arteriovenous fistula dialysis access.

Arteriovenous fistulae (AVF) and grafts (AVG) for hemodialysis access generally provide good long-term solutions for the patient with end-stage renal disease. However, complications of both AVGs and AVFs are common and require a multimodality approach to maintain their patency and continued use. Commonly encountered problems include stenosis, thrombosis, aneurysm or pseudoaneurysm formation, rupture, and infection.

Comparison of a suspended radiation protection system versus standard lead apron for radiation exposure of a simulated interventionalist.

Purpose: To evaluate the radiation protective characteristics of a system designed to enhance operator protection while eliminating weight to the body and allowing freedom of motion.

Materials And Methods: Radiation doses to a mock interventionalist were measured with calibrated dosimeters in a clinical interventional suite. A standard lead apron (SLA; Pb equivalent, 0.

Fiducial marker placement for intraoperative spine localization.

In recent years, there has been a great increase in the number of cases of image-guided fiducial marker placement for the purposes of stereotactic radiosurgery. At the authors' parent institution, a tertiary referral academic medical center, the placement of fiducial markers has also been used for the purposes of localization before spine surgery. Given the reported prevalence of "wrong-site" surgical intervention documented in the medical literature, particularly involving spinal surgery, the neurosurgical department at the authors' institution has requested the expertise of interventional radiology for assistance in preoperative spine localization.

Endovascular management of suprascapular artery pseudoaneurysm.

Pseudoaneurysms can be debilitating for patients and occasionally life threatening. Many imaging modalities may be used to assess and define these vascular lesions, and various methods have been employed in their treatment. Our patient suffered trauma to his left shoulder resulting in fracture of his clavicle following an automobile accident and subsequently was found to have a pseudoaneurysm of his left suprascapular artery on imaging.

Left colic artery pseudoaneurysm from pancreatitis presenting as upper gastrointestinal hemorrhage.

Visceral pseudoaneurysms resulting from pancreatitis occur in approximately 10% of cases. The present report describes a left colic artery pseudoaneurysm from pancreatitis presenting with active duodenal bleeding. Based on the clinical and endoscopic demonstration of duodenal bleeding, celiac and superior mesenteric arteriograms were initially obtained, and their findings were negative.
