Transcranial Dopplers Revisited: Development of Novel Markers for Cerebral Vasospasm After Aneurysmal Subarachnoid Hemorrhage.

Background Cerebral vasospasm has been monitored by conventional angiography or transcranial Doppler (TCD). While angiography is the most accurate and reliable method for detection, TCDs are a noninvasive alternative to monitor onset and resolution of vasospasm. We aim to determine whether alternative TCD parameters rather than Lindegaard ratio lead to an improved method to diagnose and potentially prevent cerebral vasospasm.

Gender and Compensation: Understanding the Impact of Gender and Gender Stereotypes in Children's Rewards.

Children's understanding of rewards for task completion was examined in the context of gender, and gender-based stereotypes. Eighty-eight children (43 girls,  = 58.39 months) completed a measure assessing gender-based occupational stereotypes.

Children's utilization of emotion expectancies in moral decision-making.

This study investigated the relevance of emotion expectancies for children's moral decision-making. The sample included 131 participants from three different grade levels (M = 8.39 years, SD = 2.

Endovascular treatment of a pseudoaneurysm after an iatrogenic axillary artery injury.

The efficacy of covered stents for treatment of upper extremity pseudoaneurysms (PSA) has not been well documented. We report a case of an 82-year-old woman who presented with a hematoma in the left infraclavicular region as a result of previous permanent pacemaker placement. Subsequent ultrasound and chest computed tomography confirmed an axillary artery PSA.

Prophylactic antibiotics prior to bacteremia decrease endovascular graft infection in dogs.

Endovascular placement of vascular stent grafts in the aorta and peripheral vessels has become a prominent tool in the armamentaria of the vascular surgeon. Despite, several reports of stent graft infection, no current guidelines exist regarding the administration of antibiotics prior to episodes of potential bacterial seeding. We sought to clarify the role of prophylactic antibiotics in preventing stent graft infection after the parenteral administration of Staphylococcus aureus (S.

An in situ adjustable endovascular graft for the treatment of abdominal aortic aneurysms.

Twenty-nine patients underwent placement of the Teramed Ariba Endovascular Graft System (Maple Grove, Minn) as part of a European Feasibility study (14 patients) and a US phase I trial (15 patients). Salient features of this modular endograft system include a crimped seamless polyester bifurcation graft supplied in three diameters and three iliac limb lengths, three types of nitinol stents including a suprarenal stent with aortic barbs, a flexible delivery system capable of controlled incremental sheath retraction, a flexible tapered lead balloon, and a telescoping technique for adjusting the length of graft coverage during surgery over a range of 3 cm. Twenty-eight of the 29 patients met the primary objective of this evaluation, which was to confirm the safety of the system, defined as the absence of major device-related adverse events and type I, III, or IV endoleaks within 1 month of implantation.
