Insights

COVID-19 increases the risk of portal vein thrombosis (PVT), a condition leading to serious complications like intestinal ischemia. Early intervention is crucial for better outcomes in patients with COVID-19-associated PVT.

Area of Science:

  • Vascular Medicine
  • Infectious Diseases
  • Gastroenterology

Background:

  • COVID-19 is associated with an increased incidence of thrombotic events.
  • Portal vein thrombosis (PVT) can lead to portal hypertension and intestinal ischemia.
  • Understanding the link between COVID-19 and PVT is critical for patient management.

Approach:

  • A systematic review following PRISMA guidelines was conducted.
  • Searches were performed on PubMed, Web of Science, and Scopus.
  • Thirty-three studies (29 case studies/series, 4 cohort/cross-sectional) were included.

Key Points:

  • PVT in COVID-19 patients occurred at a younger age compared to PVT from cirrhosis.
  • Males were predominantly affected (54.83-62.1%).
  • Common comorbidities included obesity, asthma, hypertension, and diabetes. Most thrombotic events occurred within two weeks of COVID-19 diagnosis.

Conclusions:

  • COVID-19 is linked to a higher risk of PVT.
  • Early treatment focuses on preventing thrombus progression and promoting recanalization.
  • Prompt intervention can prevent poor prognosis, including intestinal ischemia and its propagation.

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 III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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...

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

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...
