Posterior Cerebral Circulation Stroke Secondary to Foetal Origin of Posterior Communicating Artery: an Indication for Carotid Endarterectomy
Posterior cerebral circulation strokes are most commonly caused by posterior vasculature in situ thrombosis, cardiac emboli, or arterial dissection. However, the foetal origin of the posterior communicating artery is an anatomical variant of the cerebral circulation that results in communication between the internal carotid and posterior cerebral circulation. This can, therefore, rarely result in posterior cerebral territory infarction from internal carotid artery thromboembolism. This is a report of a case in which a patient suffered posterior circulatory stroke secondary to this anatomical variation of the circle of Willis.

A giant floating thrombus in the ascending aorta: a case report
A floating thrombus in an ascending aorta with normal morphology is very rare, but when it does occur, it may induce a systemic embolism or fatal stroke. The pathophysiological mechanisms of aortic mural throm...

Antimalarial and cytotoxic drugs on COVID-19 and the cardiovascular burden: Literature review and lessons to be learned.
DISCUSSION: There is no convincing clinical evidence of chloroquine, hydroxychloroquine with or without azithromycin, and remdesivir use in COVID-19. As evidence of systemic inflammation is rapidly unfolding, there is a dire need to maximize our resources to find the best possible solutions to the current crisis while conclusive evidence from clinical trials emerges.

Completion imaging techniques and their clinical role after carotid endarterectomy: Systematic review of the literature.
CONCLUSION: Completion imaging techniques can detect defects in almost 10% of patients that may lead to immediate intra-operative surgical revision with low intra-operative stroke/transient ischemic attack rate and low early carotid restenosis. During the 30-day follow-up period, in those patients, the incidence of stroke/transient ischemic attack may be low but present. This review cannot provide any evidence on which completion imaging technique is better, and the clinical impact conferred by each technique in the absence of a randomized control studies.

Flow dynamics, false lumens and implications for endografting
The complications of endovascular stenting for type B aortic dissections are well-described and include paralysis from spinal cord ischemia, retrograde dissection, stroke, and access site complications. Owing to the inherent risk associated with this procedure, current practice is to withhold endovascular therapy unless the risk-benefit balance is in favor of intervention, such as with acute malperfusion or aneurysmal degeneration. Emphasis is placed on coverage of the entry tear, which has been advocated theoretically as the primary method to restore normal aortic hemodynamics and induce false lumen thrombosis, despite no...

Surgical thromboendarterectomy for free-floating thrombus associated with cervical carotid artery dissection: A case report
Free-floating thrombus (FFT) of the cervical carotid artery is a rare but critical condition leading to stroke. The most common underlying pathology is atherosclerotic plaque; non-atherosclerotic pathologies are much rarer. Here we report a case of FFT associated with cervical carotid artery dissection that was successfully treated by surgical thromboendarterectomy.

Protamine sulfate use during tibial bypass does not appear to increase thrombotic events or affect short-term graft patency.
CONCLUSIONS: Heparin reversal with protamine sulfate after tibial or peroneal bypass grafting is not associated with higher cardiovascular morbidity, bypass thrombosis, amputation, or mortality. Additionally, there was no statistically significant difference in post-operative bleeding or thrombosis complications for patients who did not receive protamine, although the findings are suggestive of a potential difference in a more adequately powered study. Our results suggest that protamine sulfate is safe for intraoperative use without increased risk of thrombotic complications or early tibial bypass graft failure. PMID:...

Forgetting “routine” deep venous thrombosis and stroke during COVID-19 is a parallel pandemic that will be costly if ignored
The current COVID-19 pandemic has resulted in a huge strategic and clinical change within the UK National Health Service (NHS) to ensure that it can cope with the surge in demand of respiratory patients. However, when attention is acutely shifted, routine care will suffer and that could be deadly for some and enormously expensive for the NHS in the long term. Fig, A, shows the increasing public interest over time relating to COVID-19 search terms in the Google Trends health category for the United Kingdom (UK) over the last 30  days.

A New Aortic Arch Inclusion Technique With Frozen Elephant Trunk for Type A Aortic Dissection
Conclusions: The aortic arch inclusion technique with FET provides a safe alternative for TAAD treatment, with satisfactory operative results. Short-term follow-up results are encouraging, and long-term outcomes need further evaluation.

Acute Hemispheric Stroke: Full Remission Following Surgical Thrombectomy
Carotid occlusion because of embolisation or as a distal extension of a thrombus formation in an ulcerated plaque can be the cause of a devastating stroke, caused by sudden occlusion of the internal carotid artery (ICA). Often, invasive treatments are not an option because of the limited time frame. In rare situations of acute stroke onset and admission to therapy within six hours, however, aggressive recanalisation may be considered. This technical note aims to demonstrate surgical transcatheter embolectomy of intra-extra cranial ICA by reducing inflow via placing a clamp on the common carotid artery (CCA) before puncture...

Carotid endarterectomy using a flow-reversal technique in the acute period: a novel approach that may reduce intraoperative cerebral events
Lesion manipulation during internal carotid artery (ICA) surgical dissection is the most crucial stage of carotid endarterectomy (CEA); a friable part of the carotid plaque or a thrombus may detach from the arterial wall leading to cerebral embolism. Proximal protection devices used in carotid stenting (CAS) reverse the blood flow to the brain eliminating, at least after their deployment, the chance of cerebral embolism. Based on the working principle of these devices, we propose a new approach to CEA making use of a flow-reversal technique and we report its successful application in 2 high risk patient with a soft and fri...

A Novel Shaggy Aorta Scoring System to Predict Embolic Complications Following Thoracic Endovascular Aneurysm Repair.
CONCLUSIONS: This shaggy score is a useful method to predict post-operative embolic complications following TEVAR. Because the risk of embolic complications was relatively high in patients with a high shaggy score, the indication for TEVAR in such patients should be considered carefully.
