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...
The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particula...
The purpose of this study is to evaluate safety and performance of the Surpass Aneurysm-Embolization System.
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 our study was to report our experience with MISACE (minimally invasive segmental artery coil embolization) to prevent spinal cord ischemia (SCI) after endovascular repair (ER) of thorac...
Recent reports have described that endovascular treatment of coil embolization of ophthalmic artery (OphA) aneurysms has a relative risk of visual disruption caused by thromboembolic infarction of the...
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...
Duplicated middle cerebral artery (dMCA) is a rare anatomical variant that can be associated with aneurysm formation and rupture. The dMCA arises from the terminal portion of internal carotid artery w...
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.
