Carotid artery disease: clinical features and management
The most common cause of ischaemic carotid territory stroke is thromboembolism from stenoses in the extracranial internal carotid artery (ICA). In the majority, embolism is preceded by an acute change in plaque morphology thereby predisposing the patient to overlying thrombus formation and embolization. The management of patients with carotid artery disease mandates risk factor modification, antiplatelet and statin therapy in everyone. There is grade A, level I evidence that recently symptomatic patients with 50–99% NASCET stenoses gain significant benefit from carotid endarterectomy (CEA), despite a small risk of perioperative stroke.

Subsequent arterial ischemic events in patients receiving anticoagulant therapy for venous thromboembolism
Conclusions In patients receiving anticoagulation for VTE, the mortality due to PE recurrences was lower than the mortality due to ischemic events. Most independent predictors for ischemic events were also predictors for major bleeding and for recurrent PE.

Intraluminal Thrombus, Intraplaque Hemorrhage, Plaque Thickness, and Current Smoking Optimally Predict Carotid Stroke
Optimal discrimination of carotid-source stroke was obtained with intraluminal thrombus, intraplaque hemorrhage, plaque thickness, and smoking history but not ulceration or stenosis.

Case report: Intraluminal thrombus attached to the lesser curvature of the aortic arch and cerebral ischemic stroke after its surgical removal
Some cases of thrombi at the ascending and descending aorta have been reported, but there are only a few reports of intraluminal aortic arch thrombi. Most intraluminal thrombi are associated with atherosclerotic lesions at the aortic wall. Here we report a case of an intraluminal thrombus attached to the lesser curvature of the aortic arch. The thrombus was successfully and completely excised, and the pathological study suggested no obvious atherosclerotic changes in the aortic wall. Two months after surgical removal of the thrombus, the patient suffered a severe cerebral ischemic stroke caused by a newly formed thromboemb...

Intraluminal Thrombus Attached to the Lesser Curvature of the Aortic Arch and Cerebral Ischemic Stroke after Its Surgical Removal
Some cases of thrombi at the ascending and descending aorta have been reported, but there are only a few reports of intraluminal aortic arch thrombi. Most intraluminal thrombi are associated with atherosclerotic lesions at the aortic wall. Here, we report a case of an intraluminal thrombus attached to the lesser curvature of the aortic arch. The thrombus was successfully and completely excised, and the pathologic study suggested no obvious atherosclerotic changes in the aortic wall. Two months after surgical removal of the thrombus, the patient suffered a severe cerebral ischemic stroke caused by a newly formed thromboembo...

Regional collaborative quality improvement for trauma reduces complications and costs
We examined the relationship between outcomes and expenditures for trauma patients treated in collaborative participant and nonparticipant hospitals.
METHODS: Payer claims and collaborative registry data were analyzed for 30-day episode payments and serious complications in patients admitted with trauma diagnoses. Patients were categorized as treated in hospitals that had different CQI status: (1) never participated (Never-CQI); (2) collaborative participant, but patient treated before CQI initiation (Pre-CQI); or (3) active collaborative participant (Post-CQI). DRG International Classification of Diseases—9th Rev. codes...

Why is the management of asymptomatic carotid disease so controversial?
Conclusions The inescapable conclusion is that only a relatively small proportion of asymptomatic patients benefit from prophylactic CEA/CAS. The key question, therefore, remains; is society prepared to invest sufficient resources in identifying these ‘high risk for stroke’ patients so that they can benefit from aggressive BMT and CEA or CAS, leaving the majority of lower risk patients to be treated medically?

Balloon tamponade repair after inadvertent subclavian artery catheterization.
CONCLUSIONS: In patients with inadvertent subclavian artery catheterization, balloon tamponade is an effective first step in management, with primary technical success approaching 100% in cases of single lumen injury. It appears less effective in patients with double lumen injury. However, the ease of transition from balloon tamponade to stent placement supports an initial attempt at hemostasis with tamponade prior to placement of a permanent stent.

Iatrogenesis imperfecta: stroke caused by accidental carotid artery catheterization.
CONCLUSION:: Even with ultrasound-guided central venous catheterization, it is essential to remain vigilant for the early detection of vascular complications. Clinical suspicion combined with diagnostic modalities such as chest radiograph, transduction and manometry can increase the detection rates.

Cryptogenic Stroke Following Abdominal Free Flap Breast Reconstruction Surgery
Conclusion Surgeons and cardiologists should be aware of this cerebrovascular complication secondary to PFO following major reconstructive surgery such as microvascular breast reconstruction. It also serves to challenge microvascular surgeons to reconsider routine use of central venous pressure lines in free flap patients who might otherwise have good peripheral vessels for postoperative fluids and antibiotic administration.

Pulmonary embolism and stroke associated with mechanical thrombectomy
Mechanical thrombectomy offers the advantage of rapid removal of venous thrombi. It allows venous obstructions to be removed and requires shorter duration of infusion of thrombolytic agents. However, aspiration of thrombi can lead to complications, particularly pulmonary embolism and hemolysis. The validity of using vena cava filters during thrombectomy in order to avoid embolism has not yet been established. The authors report a case of massive pulmonary embolism associated with ischemic stroke in a patient with a hitherto undiagnosed patent foramen ovale. The patient developed respiratory failure and neurological deficit...

CT Perfusion Imaging in the Selection of Acute Stroke Patients to Undergo Emergent Carotid Endarterectomy
Severe acute stroke patients with critical carotid stenosis or occlusion without intracranial thrombus typically do not undergo emergent carotid thromboendarterectomy (CEA) because of the risk of reperfusion-related intracranial hemorrhage. Past studies have not consistently demonstrated benefit of early operative intervention. Cerebral computed tomography (CT), cervical and cerebral CT angiography (CTA), and cerebral CT perfusion (CTP) imaging may identify a subset of acute stroke patients without intracranial thrombus who may benefit from emergent CEA.
