Introduction: Pseudoaneurysm is a dilatation of an artery with actual disruption of one or more layers of its wall, rather than just expansion of wall layers. Pseudoaneurysms are common vascular abnormalities. Computed Tomography (CT), Magnetic Resonance Imaging (MRI), sonography, and angiography all are valuable modalities in the imaging workup of pseudoaneurysms. Conventional angiography rema...

Patients undergoing endovascular repair (EVAR) of aortoiliac or iliac artery aneurysm may require sacrifice of one or both internal iliac arteries (IIAs). Until Food and Drug Administration-approved commercial grafts became available, endovascular IIA preservation was accomplished using the "sandwich" technique, but limited information is available regarding the results of this method. After ob...

BACKGROUND AND PURPOSE The treatment of epistaxis in patients with hereditary hemorrhagic telangiectasia can be very challenging. The purpose of our study was to evaluate our experience with endovascular epistaxis embolization in patients with hemorrhagic hereditary telangiectasia and to compare this with our experience in patients treated for idiopathic epistaxis. MATERIALS AND METHODS Over ...

Many cardiac surgeons are worried about their current position and importance, and even more about how they will evolve in the coming years. The development of endovascular techniques is considerably changing patient care and will most probably continue to expand as patients express their preference for less-invasive interventions. As a result, cardiac surgery has already dramatically changed, ...

BACKGROUND Iodine contrast medium (ICM) is considered gold standard in endovascular revascularization procedures. However, nephrotoxicity and hypersensitivity to ICM are causes that limit its indiscriminate use. Carbon dioxide (CO2) contrast angiography has been used as an alternative in patients with formal contraindication to ICM. However, no studies to the present date have compared in a ran...

This article discusses the current state of minimally invasive treatment options for a variety of vascular diseases. Advances that have been introduced over the last two decades have dramatically changed the practice of vascular surgery and anesthesia. The ability to treat pathology, using both intraluminal and extraluminal means,has provided vascular surgeons, interventional radiologists, and ...

Introduction Interventional CMR has been undergoing rapid development because of the availability of MR compatible interventional catheters, and the increased performance of the MR systems themselves. Much of this development has benefited from the previous groundbreaking work in MRI guided surgical technologies ; however, intravascular techniques do not carry the requirement for an open access...

Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the ha...

OBJECTIVES To analyze the values of flow obtained with an endovascular catheter, and to determine whether they are more reliable than angiographic and clinical findings for planning and for determining the outcome of invasive radiologic treatment of hemodialysis fistulas, as well as to determine the safety of this technique during interventional radiology procedures. MATERIAL AND METHODS We u...

BACKGROUND AND PURPOSE Cortical visual loss is a rare complication of cerebral angiography without a definitive pathophysiology. Given the rapid increase in endovascular procedures used to treat cerebral aneurysms, we explored the prevalence of this complication and whether we could add to the understanding of this disorder. MATERIALS AND METHODS We performed a retrospective review of all pro...
