Acute type A aortic dissection in a patient with COVID-19

Post-COVID-19 Thoracic Aortic Rupture with an Unforeseen Spinal Epidural Hematoma

The importance of prompt diagnosis and early stenting of an aortic rupture cannot be overemphasized. We present a case of thoracic aortic rupture in a middle-aged gentleman who had recently suffered coronavirus disease 2019. The case was further complicated by the development of an unexpected spinal epidural hematoma.

Stanford Type A Aortic Dissection in A Patient with Primary Antiphospholipid Syndrome and Coronavirus Disease 2019

Acute aortic dissection is one of the most lethal diseases, affecting the lining of the aortic wall. We describe a case of Stanford Type A aortic dissection in a patient with underlying primary antiphospholipid syndrome (APS) complicated by coronavirus disease 2019 (COVID-19). APS is characterized by recurrent venous and/or arterial thrombosis, thrombocytopenia, and rarely vascular aneurysms. The hypercoagulable milieu attributable to APS and the prothrombotic state from COVID-19 posed a challenge in achieving optimal postoperative anticoagulation in our patient.

Aortic Dissection and COVID-19 Pneumonia in a Pregnant Woman at 34 Weeks of Gestation

Between 0.1% and 0.3% of all aortic dissections occur during pregnancy. Arterial hypertension, connective tissue disorders, and congenital cardiovascular anomalies-including bicuspid aortic valves-are well-known risk factors. The causality between pregnancy and aortic dissection is unclear, but there have been some observations that COVID-19 illness may increase the risk. This report describes a pregnant woman at 34 weeks of gestation who had a bicuspid aortic valve and experienced an acute aortic dissection while ill with COVID-19 pneumonia. Computed tomography confirmed a type A aortic dissection and bilateral patchy pulmonary opacities. Cesarean delivery was performed, followed by replacement of the aortic valve with a mechanical aortic prosthesis and reconstruction of the ascending aorta and hemiarch. The intraoperative course was uneventful, and the patient was successfully weaned from mechanical ventilation after 51 hours. COVID-19 during pregnancy seems to increase the risk for aortic dissection, although there is no evidence base for an association. Because guidelines for diagnosis and treatment in such complex cases are lacking, care from a multidisciplinary team is crucial for successful outcomes.

A Systematic Review of Arterial Dissections in COVID-19 Patients

INTRODUCTION

COVID-19 is often seen presenting with a myriad of signs and symptoms of multiorgan dysfunction including arterial dissection.

METHODS

Various theories have been proposed such as endothelial dysfunction triggered by hyperinflammatory response that results in rupture of atherosclerotic plaque and subsequent dissection.

RESULTS

However, the exact incidence is unknown and only case reports and case series have been published till date.

CONCLUSION

Here we carried out a systematic analysis of published case reports/series related to dissection of the aorta, coronary, cerebral, vertebral, cervical, renal, and splanchnic arteries.

The Potential Involvement of SARS‐CoV‐2 in the Immuno‐Pathogenesis of a Type A Aortic Dissection Case

The novel coronavirus disease 2019 (COVID‐19) may represent different clinical manifestations with different severities, from mild to severe. Even though the respiratory system is the mainly involved organ, numerous reports have mentioned cardiovascular complications in COVID‐19. Herein, we report a case of type A aortic dissection in a COVID‐19 patient.

In the case of severe SARS‐CoV‐2 infection, severe inflammation (i.e., cytokine storm) and downregulation of ACE2 can be associated with aortic dissection.

Cardiac surgery on patients with COVID-19: a systematic review and meta-analysis

Introduction

The COVID‐19 pandemic has had a significant impact on global surgery. In particular, deleterious effects of SARS‐CoV‐2 infection on the heart and cardiovascular system have been described. To inform surgical patients, we performed a systematic review and meta‐analysis aiming to characterize outcomes of COVID‐19 positive patients undergoing cardiac surgery.

Methods

The study protocol was registered with PROSPERO (CRD42021228533) and conformed with PRISMA 2020 and MOOSE guidelines. PubMed, Ovid MEDLINE and Web of Science were searched between 1 January 2019 to 24 February 2022 for studies reporting outcomes on COVID‐19 positive patients undergoing cardiac surgery. Study screening, data extraction and risk of bias assessment were conducted in duplicate. Meta‐analysis was conducted using a random‐effects model where at least two studies had sufficient data for that variable.

Results

Searches identified 4223 articles of which 18 studies were included with a total 44 patients undergoing cardiac surgery. Within these studies, 12 (66.7%) reported populations undergoing coronary artery bypass graft (CABG) surgery, three (16.7%) aortic valve replacements (AVR) and three (16.7%) aortic dissection repairs. Overall mean postoperative length of ICU stay was 3.39 (95% confidence interval (CI): 0.38, 6.39) and mean postoperative length of hospital stay was 17.88 (95% CI: 14.57, 21.19).

Conclusion

This systematic review and meta‐analysis investigated studies of limited quality which characterized cardiac surgery in COVID‐19 positive patients and demonstrates that these patients have poor outcomes. Further issues to be explored are effects of COVID‐19 on decision‐making in cardiac surgery, and effects of COVID‐19 on the cardiovascular system at a cellular level.

Aortic dissection and Covid-19; a comprehensive systematic review

Coronavirus disease 19 (Covid-19) has been declared as a pandemic disease since March 2020; causing wide array of signs and symptoms, many of which result in increased mortality rates worldwide. Although it was initially known as an acute respiratory disease, Covid-19 is accompanied with several extrapulmonary manifestations, of which the cardiovascular ones are of major importance. Among other cardiovascular complications of Covid-19, aortic dissection has been a significant yet underrated problem. The pathophysiology of aortic dissection consists of various inflammatory pathways, that could be influenced by Covid-19 infection. We herein have reviewed articles inclusive of aortic dissection concurrent with Covid-19 infection in a systematic manner, along with the probable similarities in pathophysiology of aortic dissection with Covid-19 infection.

Post-COVID isolated subclavian artery dissection with multiple cerebral infarctions

Background

Coronavirus disease 2019 (COVID-19) is a pandemic disease which predominantly affects the respiratory system with high critical care mortality and morbidity, yet it also causes multiple organs dysfunction in affected patients. There is a strong evidence that it increases the susceptibility of cerebrovascular strokes in such patients. Besides this prothrombotic complication, arterial dissection can be one of its mechanisms increasing the risks of stroke.

Case presentation

Herein, we report a case of spontaneous isolated subclavian artery dissection in a COVID-19 patient. Sixty-one-year-old female presented with spontaneous isolated subclavian artery dissection without any traumatic events nor history of connective tissue disorders. She had left upper limb ischemia followed by cerebellar, thalamic and occipital infarctions. Whether this patient’s subclavian artery dissection was triggered by exaggerated inflammatory response or arteriopathy secondary to COVID-19 remains speculative.

Conclusions

Nonetheless, arterial dissection can be one of its complications, it is essential for treating physicians to be attentive for the diversity of COVID-19 clinical manifestations.

Acute aortic dissection in the Marfan syndrome during the COVID-19 epidemic

A 17-year-old boy with a recent diagnosis of COVID-19 infection was admitted with acute chest pain due to type A aortic dissection and was subsequently diagnosed with the Marfan syndrome. Literature shows an increased rate of aortic dissection during flu season. The hypothesis is that a cytokine storm triggers the dissection.

Unilateral common carotid artery dissection in a patient with recent COVID-19: An association or a coincidence?

The "Corona Virus Disease 2019 (COVID-19)", caused by severe acute respiratory coronavirus 2 (SARS-CoV-2), progressed rapidly since its first outbreak, and quickly developed into a pandemic. Although COVID-19 mostly presents with respiratory symptoms, researchers have started reporting neurologic manifestations such as cerebrovascular diseases in patients, with COVID-19 as the pandemic has progressed. Herein, we report a case of 38-year-old female patient identified with a left common carotid artery dissection, with COVID-19. Clinicians must keep in mind that COVID-19 can cause vascular complications such as carotid artery dissections in the ensuing period, even after the acute phase, although there is currently a lack of sufficient evidence to identify any causal association between COVID-19 and arterial dissections.
