RESUMO

BACKGROUND: Pregnancy-associated spontaneous coronary artery dissection (PSCAD) is an important cause of chest pain and acute myocardial infarction in pregnant and postpartum women. Pregnancy is considered an isolated risk factor for spontaneous coronary artery dissection. The etiology, pathogenesis, and incidence of PSCAD are not known. CASE SUMMARY: We present a case of a 33-year-old postpartum female who presented with sudden onset chest pain and was diagnosed with spontaneous coronary artery dissection and needed urgent catheterization revealing left anterior descending coronary artery dissection. She underwent emergent coronary artery bypass graft surgery with good post-operative recovery. CONCLUSION: Most patients with PSCAD can be managed conservatively with medical management and have good outcomes. Patients with high-risk presentations benefit from the invasive approach. Coronary artery bypass graft may be required in select few patients based on angiography findings. Due to the risk of recurrent spontaneous coronary artery dissection, subsequent pregnancies are discouraged.

RESUMO

The COVID-19 pandemic has created an unprecedented global health care crisis. COVID-19 patients are found to have increased thrombotic risk. Despite being on prophylactic anticoagulation, many develop serious arterial and venous thromboembolic events. Emerging reports indicate COVID-19 may be considered a novel risk factor for portal vein thrombosis. Although, intra-abdominal infections are identified as risk factors, clostridium difficile colitis has not been typically seen as a risk factor for PVT. We report a case of an elderly female with a recent diagnosis of COVID-19 and no prior history of cirrhosis or malignancy who presented with diarrhea due to clostridium difficile infection. She developed sudden onset severe abdominal pain during the course of hospitalization. Acute portal vein thrombosis was identified on CT imaging of the abdomen, and she improved well with therapeutic anticoagulation. Acute portal vein thrombosis usually results from a combination of local and systemic prothrombotic risk factors. The combination of local infection by clostridium difficile and COVID-19 coagulopathy led to development of portal vein thrombosis in our patient. To the best of our knowledge, this is the first case of portal vein thrombosis reported in a patient with clostridium difficile infection in the setting of COVID-19 coagulopathy. During the current pandemic, clinicians should strongly consider abdominal imaging in patients presenting with abdominal pain due to clostridium difficile infection in the setting of COVID-19 to rule out complications such as portal vein thrombosis. Early diagnosis and treatment of portal vein thrombosis prevent complications of portal hypertension and intestinal infarctions.

RESUMO

BACKGROUND: Venous thromboembolism (VTE) is increasingly reported in seriously ill patients with COVID-19 infection. Incidence of VTE has been reported before and results varied widely in study cohorts. AREA OF UNCERTAINTY: Incidence of major VTE (segmental pulmonary embolism and above and proximal deep vein thrombosis) which is a contributor to mortality and morbidity is not known. Also, data is unclear on the optimal anticoagulation regimen to prevent VTE. DATA SOURCES: Multiple databases including PubMed were searched until May 12, 2020, to include studies reporting VTE in hospitalized COVID-19 adult patients. MOOSE guidelines were followed in selection, and 11 studies were included. We conducted a systematic review and meta-analysis to quantitatively assess the VTE burden in hospitalized COVID-19 patients and potential benefits of therapeutic dosing of anticoagulation compared with prophylaxis dosing for VTE prevention. THERAPEUTIC ADVANCES: Many societies and experts recommend routine prophylactic anticoagulation with heparin for VTE prevention in hospitalized COVID-19 patients. In this meta-analysis, the pooled rate of major VTE was 12.5% in hospitalized patients and 17.2% in intensive care unit patients. When therapeutic anticoagulation dosing was compared with prophylactic anticoagulation, the pooled odds ratio of VTE was 0.33 (95% confidence interval 0.14-0.75; P = 0.008, I = 0%) suggesting statistical significance with therapeutic dosing of anticoagulation for primary prevention of VTE in all hospitalized patients. However, this should be interpreted with caution as the bleeding events and safety profile could not be ascertained because of lack of adequate information. We recommend applying this finding to hospitalized COVID 19 patients only after carefully weighing individual bleeding risks and benefits. CONCLUSION: Major VTE events, especially pulmonary embolism, seem to be high in COVID-19 patients admitted to the intensive care unit. Therapeutic anticoagulation dosing seems to significantly benefit the odds of preventing any VTE when compared with prophylactic dosing in all hospitalized patients.
