Summary
Pulmonary embolism in pregnancy can be challenging to diagnose. Tenecteplase thrombolysis offers an effective treatment option with acceptable complication rates for pregnant patients.
Area of Science:
- Obstetrics and Gynecology
- Cardiology
- Pulmonology
Background:
- Pulmonary embolism (PE) diagnosis in pregnancy is complicated by physiological changes.
- Delayed diagnosis is common due to concerns about fetal radiation exposure from imaging.
- Systemic thrombolysis is rarely used in pregnancy due to perceived high risks.
Observation:
- A 37-year-old pregnant woman at 29 weeks gestation presented with syncope and dyspnea.
- The patient was diagnosed with pulmonary embolism.
- Persistent hypotension necessitated intervention.
Findings:
- Thrombolytic therapy with tenecteplase was administered.
- The patient showed excellent clinical and hemodynamic improvement.
- No maternal or fetal hemorrhagic complications occurred.
Implications:
- Tenecteplase is a viable treatment for severe pulmonary embolism in pregnancy.
- The complication rates of thrombolysis are acceptable when weighed against the risks of untreated PE.
- This case supports the judicious use of thrombolysis in pregnant patients with life-threatening PE.

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 I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
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...
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...
Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
