Identification of Patients with a Histologically Unstable Carotid Plaque Using Ultrasonic Plaque Image Analysis
Objectives: In patients with carotid stenosis the risk of stroke is highest in the first few days after onset of symptoms and it is low in asymptomatic patients. The ability to identify patients with a high (or low) probability of having a histologically unstable plaque might become a complimentary method that can refine the indications for surgical intervention.Methods: Two histopathologists, using validated American Heart Association criteria, independently graded plaques harvested during carotid endarterectomy. Preoperative Duplex images were independently assessed for juxtaluminal black area, plaque type, plaque area, ...

Identification of Patients with a Histologically Unstable Carotid Plaque Using Ultrasonic Plaque Image Analysis.
CONCLUSIONS: Computerized plaque analysis has the potential to identify patients with histologically unstable carotid plaques. This model requires validation, but offers the potential to influence patient selection for emergency interventions and the monitoring of medical therapy.

Trapped cerebral thrombectomy device: A case report of a rare complication.
Abstract Intravenous thrombolysis with recombinant tissue plasminogen activator is currently the standard therapy for acute ischaemic stroke when started within 4.5 h of symptom onset. Systemic thrombolytic therapy can, however, lead to potentially lethal bleeding complications and is contra-indicated in several circumstances. Intra-arterial thrombolysis and/or intra-arterial thrombectomy can overcome these drawbacks and even increase the rate of recanalization. While intravenous thrombolysis is a relatively non-complex treatment, intra-arterial therapy in acute ischaemic stroke patients requires a dedicated int...

Therapeutic application of contrast-enhanced ultrasound and low-dose urokinase for thrombolysis in a porcine model of acute peripheral arterial occlusion
In this study, we investigated the effect of additional US and microbubbles on standard low-dose intra-arterial thrombolysis in a porcine model of extensive peripheral arterial occlusion.

Minimal Thoracotomy Thoracic Bifemoral Bypass in the Endovascular Era
Conclusions: Mini-TBF bypass provides another alternative to successfully revascularize Trans-Atlantic Inter-Society Consensus II type D lesions in patients with prior abdominal revascularization, pelvic anatomy with a critical IMA, or calcification/thrombus of the infrarenal/juxtarenal aorta precludes control.

Perioperative morbidity and mortality after noncardiac surgery in young adults with congenital or early acquired heart disease: a retrospective cohort analysis of the national surgical quality improvement program database.
Abstract An increasing number of patients with congenital heart disease survive to adulthood. Expert opinion suggests that noncardiac surgery is a high-risk event, but few data describe perioperative outcomes in this population. Using the National Surgical Quality Improvement Program database, we identified a cohort of patients aged 18 to 39 years with prior heart surgery who underwent noncardiac surgery between 2005 and 2010. A comparison cohort with no prior cardiovascular surgery was matched on age, sex, race/ethnicity, operation year, American Society of Anesthesiologists physical status, and Current Procedura...

Subclavian Stump Syndrome Causing a Posterior Circulation Stroke after Thoracic Endovascular Aneurysm Repair (TEVAR) with Adjunctive Carotid to Subclavian Bypass and Endovascular Embolization of the Left Subclavian Artery
Conclusions: Consideration should be given to ligating the subclavian artery immediately proximal to the vertebral artery origin when performing adjunctive carotid subclavian bypass during TEVAR. If this is not done, surveillance computed tomography scans should monitor for the development of propagating thrombus in the subclavian stump.

Aortoiliac Occlusive Disease Presenting as Sudden Onset Paraplegia
Thromboembolism and atherosclerotic stenosis both can cause arterial occlusion. Aortoiliac occlusive disease involving bifurcation of the aortoiliac artery induces symptoms of ischemia such as claudication and pain of buttocks and thighs, decreased bilateral femoral pulses, and impotence. Here, we describe a 58-year-old woman with a past history of atrial fibrillation and lacuna stroke with minimal right side weakness. She presented to our emergency department with sudden onset bilateral pain in the legs and paraplegia. A comprehensive examination revealed paresthesia and decreasing bilateral distal pulses. Computed tomogr...

Follow-up outcomes of hybrid procedures for thoracoabdominal aortic pathologies with special focus on graft patency and late mortality
Conclusions: A hybrid procedure for thoracoabdominal aortic pathologies in high-risk patient is feasible but carries a significant rate of early and midterm reintervention and death. Long-term surveillance of the visceral bypass is necessary because one-third of the patients will have bypass-related complications.

Posterior transverse plication of the internal carotid artery to correct for kinking
Conclusions: Although the indications for additional shortening procedures following CEA need to be defined, in this small series, PTP as an additional shortening procedure of the ICA following CEA seems feasible and safe with no additional periprocedural risk for narrowing at the plicature or thrombosis of the endarterectomy plane. However, restenosis at the plicature may hamper the long term benefit of carotid reconstruction.

Finding a Needle in the Common Carotid Artery 3 Years after Ingestion
A woman presented with an ischemic stroke involving the right middle cerebral artery. Investigations revealed a foreign body in the cervical area. It was identified as a metal needle, perforating the posterior pharyngeal wall and migrating into the right common carotid artery (CCA). Three years previously, this patient had complained of odynophagia, brought on by needle ingestion. Three days before her stroke, she had hematemesis, caused by migration of the needle into the CCA. The stroke was caused by migration of the thrombus. This type of event is rarely encountered in Europe. Early recognition could avoid dangerous vascular complications.

The Validity of CHADS2 Score as a Predictor of De Novo Postoperative Atrial Fibrillation in Adult Cardiac Surgery Patients
Occurrence of atrial fibrillation (AF) following cardiac surgery portends higher mortality and is associated with increased costs and risk of thromboembolism. While many anatomic and patient factors have been associated with AF, a simple clinical scoring system to identify patients at high risk of developing AF is lacking. The CHADS2 score is widely utilized to predict the risk of stroke in patients with AF. We aimed to assess the utility of this scoring algorithm in predicting the likelihood of de novo postoperative AF in cardiac surgery patients.

Midterm Outcomes of Carotid-to-Carotid Bypass for Hybrid Treatment of Aortic Arch Disease
Conclusions: CCBs are durable at midterm follow-up. No relevant superiority was identified between the 2 types of CCB; subcutaneous and retropharyngeal routes proved to be equally safe.

Ischemic Stroke due to Paradoxical Embolism Arising from a Popliteal Vein Aneurysm
We present the case of a 63-year-old, right-handed man who presented to the emergency department with transitory ischemic accident (left superior extremity regressive monoplegia). Complete etiologic work-up led to the discovery of both a patent foramen ovale associated with an septum interauricular aneurysm, and of a PVA without mural thrombus. The diagnosis of brain paradoxical embolism was retained. The unique potentially embolic cause was the presence of the PVA. We decided to treat the PVA surgically to avoid a further cerebral vascular episode. Although uncommon, venous etiology must be considered for stroke.
