Beyond Traditional Risk Factors: Cocaine Abuse and Pulmonary Embolism

Area of Science:

• Cardiology
• Pulmonology
• Emergency Medicine

Background:

• Pulmonary embolism (PE) is a life-threatening condition requiring urgent diagnosis and treatment.
• Massive PE, characterized by hemodynamic instability or right ventricular dysfunction, carries high morbidity and mortality risks.

Observation:

• A 42-year-old male with a history of cocaine abuse presented with syncope, dyspnea, and pleuritic chest pain.
• Clinical findings included tachycardia, hypoxemia, elevated D-dimer, and echocardiographic evidence of right heart strain.
• Computed tomography pulmonary angiography (CTPA) confirmed extensive bilateral pulmonary emboli.

Findings:

• The patient had a massive, high-risk PE with significant clot burden, particularly in the right pulmonary artery.
• Mechanical thrombectomy was performed to remove the obstructing clots.
• The procedure successfully reduced the clot burden and improved pulmonary artery perfusion.

Implications:

• This case highlights the critical role of prompt diagnosis and intervention in massive PE.
• Mechanical thrombectomy can be an effective treatment for massive PE, even in younger patients with risk factors like substance abuse.
• Early intervention can mitigate the severe consequences of massive PE, improving patient survival and recovery.
