Bilateral pulmonary embolism and pulmonary infarctions in active ulcerative colitis

Area of Science:

• Gastroenterology and Hematology
• Vascular Medicine

Background:

• Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis (UC), are chronic conditions associated with a significantly increased risk of thromboembolism (TE).
• Understanding the specific risks and management strategies for TE in IBD patients is crucial for improving patient outcomes.

Observation:

• A young male patient with active ulcerative colitis presented with acute symptoms of shortness of breath and syncope.
• Diagnostic imaging revealed extensive bilateral pulmonary embolism (PE) with evidence of right heart strain and pulmonary infarctions.

Findings:

• The patient's presentation of severe PE was directly linked to his active ulcerative colitis.
• Initial management involved a heparin infusion, followed by transition to a direct-acting oral anticoagulant (DOAC).

Implications:

• This case underscores the critical need for vigilance regarding thromboembolic complications in patients with active IBD.
• Effective anticoagulation therapy, including DOACs, can lead to clinical improvement in IBD-associated pulmonary embolism.
• Further research into the mechanisms linking IBD and TE may reveal novel therapeutic targets.
