Determinants and outcomes of asystole during carotid artery stenting.

Purpose: To examine the predictors and outcomes of asystole in patients who undergo carotid artery stenting (CAS).

Methods: Forty-three patients (24 men; median age 69 years) with asystole were identified after reviewing the case records of 884 patients who underwent CAS at our institution between 1997 and 2009. The control group comprised 678 patients who underwent stenting in the carotid sinus area without asystole.

Endovascular exclusion of a thoracoabdominal aortic aneurysm after retrograde visceral artery revascularization.

Historically, open surgical repair of thoracoabdominal aortic aneurysms has been associated with high morbidity and mortality rates. Furthermore, endovascular exclusion alone can restrict blood flow to visceral arteries. We report a case of thoracoabdominal aortic aneurysm that was repaired using a hybrid approach: surgery followed by an endovascular procedure.

Endovascular repair of a giant carotid pseudoaneurysm with the use of Viabahn stent graft.

A 72-year-old woman presented with a large pulsatile anterior right neck mass with compressive symptoms of dysphagia and hoarseness. This was due to a large (6 cm by 4 cm) postcarotid endarterectomy pseudoaneurysm of the right common carotid artery. Successful endovascular exclusion of the pseudoaneurysm was performed with a Viabahn stent graft with significant decrease in the size on follow-up.

Percutaneous intervention for the treatment of hypoplastic aortoiliac syndrome.

Hypoplastic aortoiliac syndrome (HAIS) occurs in young women and is characterized by a small infrarenal aorta with a hypoplastic iliofemoral arterial system and advanced atherosclerotic disease. Of 304 aortoiliac interventions (AoI), 30 female patients (mean age, 50 +/- 5 years) had HAIS. HAIS patients were less likely to have coronary disease (33% vs.

Mechanical trauma as a cause of late complications: after AneuRx Stent Graft repair of abdominal aortic aneurysms.

We present a series of 4 patients in whom mechanical trauma was identified as a factor in the development of late complications after AneuRx Stent Graft placement for repair of abdominal aortic aneurysms. In all 4 patients, Type I or III endoleaks (and pseudoaneurysms in 2 patients) were discovered several months after abdominal aortic aneurysm repair with the AneuRx device. Two patients had sustained blunt abdominal trauma in a car accident one had suffered a traumatic fall, and another had been participating in vigorous rowing activity.

Aortic stent-graft infection due to a presumed aortoenteric fistula.

Purpose: To report a case of late stent-graft infection with aortoenteric fistula.

Case Report: A 76-year-old Colombian man received an AneuRx stent-graft for a 5.5-cm infrarenal AAA.

Correlation of periprocedural systolic blood pressure changes with neurological events in high-risk carotid stent patients.

Purpose: To examine retrospectively the magnitude of change in systolic blood pressure (SBP) during carotid artery stenting and its relationship to neurological events.

Methods: In a 5-year period ending October 2000, 60 patients (36 men; mean age 67 +/- 9 years) were enrolled in a study to evaluate stenting in symptomatic or asymptomatic high-risk patients with > or =70% carotid artery stenosis. The majority (48, 80%) of the patients were symptomatic.

Successful treatment of aortic endograft thrombosis with rheolytic thrombectomy.

Purpose: To report the benefits of rheolytic thrombectomy for treating aortic endograft thrombosis.

Methods: Of 40 patients who received the Ancure bifurcated endograft to treat abdominal aortic aneurysm (AAA) during a 9-month period, 6 (15%) patients (6 men; mean age 62.6 years, range 53-77) developed thrombosis of the endograft at an average of 9 weeks (range 1-20 months).
