To evaluate the reduction in type II endoleak risk after introducing a new prevention method, "thrombization" or clotting of the aneurysm sac, during endovascular aneurysm repair (EVAR) versus the standard EVAR technique. From September 1999 to December 2008, 469 consecutive patients underwent EVAR for AAA at our institution. In 2003, ...

Endovascular aneurysm repair (EVAR) exposes patients to radiation during the procedure and in subsequent follow-up. The study goal was to calculate the radiation dose in our unit and compare it against other published data and national guidelines. All EVAR procedures were identified from a prospectively maintained database. Radiation dose, screening ...

It is uncertain which baseline factors are associated with graft-related complications and reinterventions after endovascular aneurysm repair (EVAR) in patients with a large abdominal aortic aneurysm. Patients randomized to elective EVAR in EVAR Trial 1 or 2 were followed for serious graft-related complications (type 2 endoleaks excluded) and reinterventions. Cox ...

The principal aim of this study was to demonstrate that significant sac retraction (SSR) was a predictive marker of durable success after endovascular aortic repair (EVAR). If verified, follow-up (FU) of patients with SSR may become unnecessary. In addition, the clinical features of the patients and aneurysms were analyzed to ...

To better understand the development of hydrocephalus of different origins, we evaluated cytokine and growth factor concentration in cerebrospinal fluid from patients with hydrocephalus. CSF was collected from patients developing hydrocephalus following hemorrhage (n = 15), patients with normal pressure hydrocephalus (n = 10), and following the embolization of unruptured intracranial aneurysms (n = 9). Myelography ...

The International Subarachnoid Aneurysm Trial (ISAT) concluded that "there is currently no reason to doubt that the reduction of dependent survival or death after endovascular coiling seen in all patients in the ISAT cohort should not be valid in the elderly". We feel that this generalization requires further investigation to ...

Most studies of thoracic endovascular aortic repair (TEVAR) published since the technology gained US Food and Drug Administration (FDA) approval in March 2005 have included multiple applications including dissection, trauma, and "hybrid" approaches, all of which are currently "off-label." However, little post-approval data exist for the only FDA-approved application, namely ...

Improving the safety of elective abdominal aortic aneurysm (AAA) repair has become an imperative. Five well-described risk-scoring systems developed on open aneurysm repair (OR) were tested on a multicenter contemporary sample of patients undergoing endovascular repair of AAA (EVR) to determine if they predicted 30-day morbidity and mortality. The Glasgow ...

Delayed ischemic neurologic deficit (DIND) is a serious and poorly understood complication of aneurysmal subarachnoid hemorrhage. Although advances in treatment have improved prognosis for these patients, long-term clinical outcomes remain disappointing. Historically, angiographic vasospasm was thought to result in a DIND, although an increasing body of evidence suggests that this ...

BACKGROUND: Vasospasm is one of the important factors associated with the functional prognosis after subarachnoid hemorrhage (SAH). Intracisternal administration of thrombolytic agents to dissolve subarachnoid clots may be responsible for bleeding complications. The efficacy and safety of cisternal irrigation therapy using low-dose tissue plasminogen activator were evaluated. METHODS: Sixty patients ...

Previous studies of spontaneous subarachnoid hemorrhage (SAH) have shown that global cerebral edema on the first computed tomography scan is associated with a more severe initial injury and is an independent predictor of poor outcome. Effects of secondary ischemic events also influence outcome after SAH. This study demonstrates that early ...

Endovascular repair of abdominal aortic aneurysm was originally developed for patients who were considered to be physically ineligible for open surgical repair. Data are lacking on the question of whether endovascular repair reduces the rate of death among these patients. From 1999 through 2004 at 33 hospitals in the United ...
