Shewanella algae: a rare cause of necrotizing fasciitis.

Background: The genus Shewanella consists of motile, gram-negative, facultative anaerobes found in marine environments. Shewanella putrefaciens and Shewanella algae are the two species with documented pathogenicity in human beings. Most documented cases of S.

Endovascular palliation of multivessel blowout syndrome in the setting of a nonresectable neck sarcoma.

Carotid blowout syndrome is a rare life-threatening complication of head and neck malignancy. Current literature has focused exclusively on the carotid system and associated branches. We present a unique case of multivessel blowout in the setting of a large nonresectable neck sarcoma requiring various endovascular techniques for palliation.

Vascular complications associated with arteriotomy closure devices in patients undergoing percutaneous coronary procedures: a meta-analysis.

Objectives: This study was designed to assess the safety of arteriotomy closure devices (ACDs) versus mechanical compression by meta-analysis in patients undergoing percutaneous transfemoral coronary procedures.

Background: Although ACDs are widely applied for hemostasis after percutaneous endovascular procedures, their safety is controversial.

Methods: Randomized, case-control, and cohort studies comparing access-related complications using ACDs versus mechanical compression were analyzed.

In-flight radiation exposure during pregnancy.

During high-altitude flight, the cosmic radiation dose rate in an airliner is greater than it is at ground level. For a casual traveler, the impact on pregnancy from cosmic radiation exposure during flight is trivial. Pregnant frequent flyers, pilots, and flight attendants can, however, receive exposures that exceed current recommended values if they do not appropriately modify their work schedules.

Impact of symptomatic peripheral arterial disease on 1-year mortality in patients undergoing percutaneous coronary interventions.

Purpose: To determine the impact of symptomatic peripheral arterial disease (PAD) on clinical outcomes in patients treated with percutaneous coronary interventions (PCI).

Methods And Results: Symptomatic PAD was identified in 1969 (18.9%) of 10440 consecutive patients undergoing PCI.

Carotid stenting with distal-balloon protection via the transbrachial approach.

Purpose: To document the feasibility of brachial artery access for carotid stenting with distal-balloon protection of the internal carotid artery (ICA).

Technique: Via percutaneous access to the brachial artery, a large double-curve catheter is advanced into the aortic arch over a hydrophilic guidewire to cannulate the left common carotid artery. Following sheath exchange, a GuardWire distal-protection balloon is positioned within the left ICA distal to the stenosis.

Subarachnoidal hemorrhage following carotid stenting with the distal-balloon protection.

A 61-year-old man underwent carotid stenting with the distal-balloon protection system for symptomatic carotid artery stenosis. During the procedure, progressive elevation of the systolic blood pressure occurred, reaching a peak of 220 mm Hg immediately following deflation of the distal balloon. This was associated with severe headaches and progressive deterioration in the mental status to a coma.

Embolization via collateral circulation during carotid stenting with the distal balloon protection system.

Purpose: To describe a potential route for embolization to the middle cerebral artery (MCA) during carotid stenting with the distal balloon protection system.

Case Report: An 82-year-old man with symptomatic severe carotid artery stenosis underwent elective carotid stenting with distal-balloon protection. Despite complete occlusion of the distal internal carotid artery, frequent emboli were detected in the ipsilateral MCA by transcranial Doppler (TCD) during the procedure.
