Application of 2-dimensional contrast studies during pericardiocentesis
The American Journal of Cardiology
|November 1, 1983
Summary
Two-dimensional contrast echocardiography accurately guided needle placement during pericardiocentesis in patients with pericardial effusion. This technique confirmed needle position, preventing misplacement and aiding fluid aspiration.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Pericardial effusion diagnosis and management can be challenging.
- Accurate needle placement is crucial for pericardiocentesis.
Purpose of the Study:
- To evaluate the utility of 2-dimensional contrast echocardiography in guiding needle placement for pericardiocentesis.
Main Methods:
- 16 patients with pericardial effusion underwent 2-dimensional echocardiographic contrast studies.
- A 4-chamber view was used, and saline solution was injected to visualize needle position.
- Contrast microbubbles were observed in all patients.
Main Results:
- Needle position was visualized in 9 patients.
- Inadvertent needle placement in the left or right ventricle was identified in 3 patients.
- Contrast confirmed needle location in the pericardial sac for 2 patients with difficult aspiration.
- A negative contrast effect suggested a stab wound laceration site in one patient.
Conclusions:
- 2-dimensional contrast echocardiography is a valuable tool for confirming needle position during pericardiocentesis.
- This technique enhances procedural safety and efficacy by preventing misplacement and facilitating fluid aspiration.
