Insights

This case highlights a rare instance of mesenteric artery thrombosis in a COVID-19 patient presenting with gastrointestinal symptoms. Early recognition of thromboembolic events is crucial for managing severe coronavirus disease 2019.

Area of Science:

  • Vascular Medicine
  • Infectious Diseases
  • Gastroenterology

Background:

  • Coronavirus disease 2019 (COVID-19) is increasingly recognized as a multisystem inflammatory condition.
  • Thromboembolic complications, including deep venous thrombosis, pulmonary embolism, and stroke, are reported with higher frequency in COVID-19 patients.
  • Gastrointestinal manifestations can occur in COVID-19, potentially complicating diagnosis.

Observation:

  • A 75-year-old female with COVID-19 presented with progressive diffuse abdominal pain, diarrhea, and vomiting.
  • Abdominal computed tomography revealed evidence of mesenteric artery thrombosis, a rare but life-threatening complication.
  • The patient's gastrointestinal symptoms initially masked the severity of the underlying vascular event.

Findings:

  • Mesenteric artery thrombosis is an uncommon but critical thromboembolic complication associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
  • Gastrointestinal symptoms in COVID-19 patients can obscure the diagnosis of abdominal thromboembolic events.
  • Prompt diagnosis and management of mesenteric artery thrombosis are essential for patient survival.

Implications:

  • Clinicians should maintain a high index of suspicion for abdominal thromboembolic events in COVID-19 patients presenting with gastrointestinal symptoms.
  • Differential diagnosis in COVID-19 should include vascular complications beyond respiratory manifestations.
  • Early identification of mesenteric artery thrombosis can significantly improve patient outcomes in the context of SARS-CoV-2 infection.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis I: Introduction01:30

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
