Cement Pulmonary Embolus Complicating Percutaneous Vertebroplasty
Radiology Case Reports
|June 17, 2016
Summary
A rare complication of percutaneous vertebroplasty, cement pulmonary embolus, occurred due to methylmethacrylate extravasation. This case highlights diagnostic and management strategies for this serious event.
Area of Science:
- Interventional radiology
- Cardiopulmonary medicine
- Neurosurgery
Background:
- Percutaneous vertebroplasty is a minimally invasive procedure for treating vertebral compression fractures.
- Methylmethacrylate cement is commonly used, but carries risks such as extravasation.
- The paravertebral venous plexus can provide a pathway for cement migration.
Observation:
- A 63-year-old woman developed acute respiratory distress post-procedure.
- Radiographic imaging revealed cement pulmonary emboli.
- The emboli originated from methylmethacrylate extravasation during vertebroplasty.
Findings:
- Cement pulmonary embolus is a potentially fatal complication of vertebroplasty.
- Early radiographic diagnosis is crucial for prompt management.
- Prevention strategies include careful cement injection and monitoring.
Implications:
- This case underscores the importance of vigilance during vertebroplasty.
- Understanding cement migration pathways aids in preventing complications.
- Effective management strategies can improve patient outcomes in cement embolism cases.

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...

1.1K
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...

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...

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, 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...

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
