Trichogramma wasps are tiny hymenopterous egg parasitoids widely used in biological control programs worldwide. The huge quantities of insects necessary for inundative releases are mainly produced on factitious hosts like Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae), or on silkworms. In order to simplify production, increase its flexibility, and(More)
PURPOSE Type II endoleak after endovascular abdominal aortic aneurysm repair is a failure of aneurysm sac exclusion with unknown long-term consequences. Elevated aneurysm sac pressures documented in these patients have led us to aggressively treat type II endoleaks with percutaneous transluminal coil embolization (PTCE). The purpose of this study was to(More)
BACKGROUND There are few large studies in the literature that document the clinical outcome of an acute dissection of the distal thoracic aorta (ADDA), particularly since the advent of percutaneous techniques for therapeutic and prophylactic treatment of complications of ADDA. The goal of this study was to evaluate the outcome of ADDA with respect to(More)
Although aortic endograft iliac limb occlusion is an uncommon event, its treatment is problematic because standard surgical thrombectomy risks graft dislodgment or component separation. Although femorofemoral bypass grafting can restore perfusion to the affected limb, its longevity may be inferior to reestablishing patency of the endograft itself and(More)
OBJECTIVE Endovascular aneurysm repair (EVAR) has become a popular treatment for abdominal aortic aneurysm (AAA). This study examines conformational changes in the infrarenal aortas of patients in whom proximal seal zone failures (PSF) developed after EVAR. METHODS All 189 patients with aortic endograft underwent routine post-EVAR computed tomographic(More)
The preservation of internal iliac artery (IIA) flow during endovascular repair of abdominal aortic aneurysms (er-AAA) remains a controversial area. Ectasia and aneurysmal disease of the iliac arteries represent a formidable challenge to the endovascular surgeon, particularly when aortic neck length and diameter are suitable for er-AAA. We describe a(More)
Takayasu's arteritis (TA) is a chronic inflammatory disease of unknown etiology that can produce stenosis, occlusion, or aneurysmal degeneration of large arteries. TA occurs worldwide but disproportionately affects young females of Asian descent. A variable acute phase of largely constitutional symptoms is followed by a chronic phase in which symptoms(More)
Aortic endografting has quickly been accepted as a less morbid method of aneurysm repair. However, preservation of the aortic sac after endografting remains a liability of this procedure. Late rupture has occurred, albeit rarely. Graft infections are another rare complication of endografting. We present the first reported case, to our knowledge, of aortic(More)
Anesthetic techniques vary widely in the endovascular repair of abdominal aortic aneurysms (EVAR). Previous studies have demonstrated the feasibility of using local anesthesia. However, the ideal anesthetic technique has not been determined. This study examines whether anesthetic technique influences the outcomes of EVAR. Data regarding demographics, risk(More)
