PURPOSE To assess the feasibility of combining stent implantation in the parent artery with endosaccular coil placement for the treatment of experimentally created wide-necked aneurysms. METHODS Wide-necked aneurysms were surgically created on the common carotid artery in 12 swine. A metal stent was endovascularly implanted across each aneurysm neck and its effect documented anigiographically...

The dynamic, hemodynamic impact of a cervical dissection on an ipsilateral, intracranial saccular aneurysm has not been well illustrated. This 45-year-old female was found to have a small, supraclinoid aneurysm ipsilateral to a spontaneous cervical internal carotid artery dissection. With healing of the dissection, the aneurysm appeared to have significantly enlarged. Retrospective review of th...

Despite recent advances in three-dimensional imaging based on a voxel-rendering method, these techniques do not simulate the morphological changes that occur during surgery. The authors' goal was to develop a computer-graphics model to simulate the manipulation that occurs during surgery when clipping a cerebral aneurysm. The authors developed an application program to interpolate the contours ...

Objective: To investigate the three-dimensional reconstruction technique and intraoperative postural changes in the interventional treatment of cerebral aneurysm. Methods: A total of 52 cases involving patients with a definite CT diagnosis of cerebral aneurysm in our hospital were selected from July 2014 to August 2015. The cases were randomly and equally divided into observation and control gr...

aortic aneurysm is also increasing (1). Recent studies have shown that abdominal aortic aneurysms were detected in 4% of men and women between 65 and 80 years old and 11% of men aged 60 or over (2-5). An aortic aneurysm can be readily detected by measuring aortic diameter; dilatation of 50% or more than expected value, or that of the proximal segment, indicates its presence (6). However, the ru...

We report two HIV infected patients with ruptured abdominal aneurysm by using endovascular aneurysm repair (EVAR) technique. A 59-year-old Thai man had a ruptured abdominal aortic aneurysm and a 57-year-old man had a ruptured iliac artery aneurysm. Both patients had a CD4 level below 200 μ/L indicating a low immune status at admission. They were treated by EVAR. Neither patient had any complica...

We present a case of stent-assisted coil embolization of a wide-necked renal artery aneurysm performed at our institution. The technique involved a stent being delivered over the neck of the aneurysm. Subsequently a catheter was placed into the aneurysm through the stent mesh and the aneurysm was then filled with detachable coils. Complete aneurysm occlusion was obtained and there was no eviden...

Figure 2: An aortogram revealed a giant aneurysm (arrow heads) arising from the aortic root. There was extremely slow contrast filling and washout of the giant aneurysm (A and B). A right ventricular angiogram demonstrated obstruction at the main pulmonary artery (C). Emergent surgery was performed because of the patient’s severe condition. After opening the pericardium, a giant aneurysm with d...

IMPORTANCE Fluoroquinolones have been associated with collagen degradation, raising safety concerns related to more serious collagen disorders with use of these antibiotics, including aortic aneurysm and dissection. OBJECTIVE To examine the relationship between fluoroquinolone therapy and the risk of developing aortic aneurysm and dissection. DESIGN, SETTING, AND PARTICIPANTS We conducted a...

Purpose: Endotension has been implicated in complications following the endovascular repair of abdominal aortic aneurysm (AAA) such as continued AAA expansion and rupture, proximal aneurysm neck dilation, and endovascular graft migration. To begin to evaluate the role of endotension in the mechanisms of post-repair problems, the magnitude and distribution of endotension in an excluded aneurysm ...
