A totally percutaneous approach to endovascular abdominal aortic aneurysm repair (PEVAR) has been shown in multiple reports to be feasible, but carries attendant risks that appear to increase with increasing sheath size. We report our methods and sequential PEVAR case experience using a new delivery system having an integrated 19Fr introducer sheath for treatment of patients with aortic necks up to 32 mm in diameter.
A single institution, prospective, controlled evaluation was conducted in 57 consecutive patients with abdominal aortic aneurysm who underwent PEVAR between December 2008 and April 2010. All patients have been followed for at least 30 days.
Patients presented at a mean age of 74 years with median AAA diameter of 5.4 cm preprocedurally. Calcified/tortuous access vessels were identified in 98% of patients. All PEVAR procedures with adjunctive "pre-close" use of the Prostar XL closure device were performed in a hybrid endovascular suite with patients maintained under conscious sedation and local anesthesia. The anatomically-fixed bifurcated stent graft and aortic/limb extensions as needed were implanted via the 19 Fr indwelling introducer sheath with minimal blood loss (79 mL). Technical success was 98%, with one conversion to open repair attributable to very small diameter (4 mm) access vessels. Cumulatively, major access-related complications were observed in five patients (8.8%) within 30 days.
PEVAR using the IntuiTrak System with 19Fr introducer sheath with vessel closure facilitated by the Prostar XL device is feasible, even in patients with challenging access anatomy. Further evaluation in a prospective, multicenter, randomized trial is warranted.

Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedur...
Aortic disease is a lifelong, progressive illness that may require repeated intervention over time. We reviewed our 25-year experience with open redo thoracoabdominal aortic aneurysm (TAAA) and descen...

Prognosis for women with abdominal aortic aneurysm might be worse than the prognosis for men. We aimed to systematically quantify the differences in outcomes between men and women being assessed for r...
Background Thresholds for repair of abdominal aortic aneurysms vary considerably among countries. Methods We examined differences between England and the United States in the frequency of aneurysm rep...
Abdominal aortic aneurysm has a lower incidence in the female population, but a higher complication rate. It was been hypothesized that some anatomical differences of abdominal aortic aneurysm in wome...
The purpose of this trial is to assess whether the new endovascular repair technique of the abdominal aortic aneurysm (AAA) is an adequate substitute of the conventional AAA repair.
The purpose of this study is to compare the cost effectiveness, quality of life and outcomes of the endovascular stent graft repair with the open surgical repair of abdominal aortic aneury...
Abdominal aortic aneurysm (AAA) is a life threatening disease. There is a consensus to propose surgical repair in patients with a reasonable operative risk when the AAA exceeds 5 cm in dia...
The durability of endovascular aneurysm repair (EVAR) has been limited by development of endoleaks which may be secondary to progressive aortic degeneration by matrix metalloproteases (MMP...
After endovascular abdominal aortic aneurysm repair, life-long follow-up is needed to monitor the effectiveness of exclusion of the aneurysm sac from blood flow. For this reason, aneurysm ...
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.
Cardiovascular manifestations of SYPHILIS, an infection of TREPONEMA PALLIDUM. In the late stage of syphilis, sometimes 20-30 years after the initial infection, damages are often seen in the blood vessels including the AORTA and the AORTIC VALVE. Clinical signs include syphilitic aortitis, aortic insufficiency, or aortic ANEURYSM.
An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.
Solitary lesions of bone that typically cause a bulging of the overlying cortex bearing some resemblance to the saccular protrusion of the aortic wall in aortic aneurysm, hence the name. (Dorland, 27th ed)
An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.

A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
