Intracranial aneurysm treatment with coil embolization is associated with relatively low complete occlusion and high recanalization rates. The investigators evaluate whether Willis covered...
This research study is being done to test the effectiveness of a new generation FDA approved device for treating aneurysms compared to the current standard device for endovascular aneurysm...
Middle meningeal artery (MMA) embolization via a minimally invasive endovascular approach has been attempted with the goal of eliminating the arterial supply to the vascularized membrane. ...
The purpose of this study is to evaluate safety and performance of the Surpass Aneurysm-Embolization System.
Background and Purpose: Congenital coronary artery fistula (CAF) is an uncommon anomaly. In some patients they can became symptomatic, associated with significant morbidity and mortality. ...
Chronic unilateral hematuria (CUH) is characterized by intermittent or continuous gross hematuria that cannot be diagnosed using standard radiology and hematology. The authors report a case of CUH wit...
Herein, we describe a technique for stent-assisted coil embolization with a spring-shaped microcatheter in a patient with an M1 ultrawide-necked circumferential aneurysm in the middle cerebral artery ...
Segmental arterial mediolysis is a rare disease characterized by idiopathic noninflammatory vasculopathy involving small to medium arteries. Here, we report a case of ruptured cerebral and abdominal a...
True degenerative aneurysms involving the donor renal artery after kidney transplantation are rather rare. The indications for operation and optimal therapy to combat this vascular complication are st...
Surgical repair of extensive thoracic aortic disease induced by repeated aortic dissection is challenging due to its invasive nature in some cases. We report a rare case of successful endovascular rep...
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Ischemia or infarction of the spinal cord in the distribution of the anterior spinal artery, which supplies the ventral two-thirds of the spinal cord. This condition is usually associated with ATHEROSCLEROSIS of the aorta and may result from dissection of an AORTIC ANEURYSM or rarely dissection of the anterior spinal artery. Clinical features include weakness and loss of pain and temperature sensation below the level of injury, with relative sparing of position and vibratory sensation.

Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Postoperative hemorrhage from an endovascular AORTIC ANEURYSM repaired with endoluminal placement of stent grafts (BLOOD VESSEL PROSTHESIS IMPLANTATION). It is associated with pressurization, expansion, and eventual rupture of the aneurysm.
