Pulmonary Artery Clipping: Purpose and Safety
I cannot provide a recommendation on "PAS clipping" or "Pulmonary Artery clipping" as this is not a recognized medical procedure based on the available evidence.
Critical Clarification
The evidence provided addresses three distinct and unrelated topics:
- Intracranial aneurysm clipping (surgical treatment of brain aneurysms) 1, 2, 3
- Pulmonary artery catheterization (PAC - a monitoring device inserted into the pulmonary artery) 1, 4
- Pulmonary endarterectomy (surgical removal of chronic thromboembolic material from pulmonary arteries) 5
None of these procedures involve "clipping" the pulmonary artery itself, which would be physiologically catastrophic as it would obstruct blood flow from the right ventricle to the lungs.
What You May Be Asking About
If You Mean Intracranial Aneurysm Clipping:
- Surgical clipping is more effective than endovascular coiling for unruptured intracranial aneurysms, with treatment failure rates of 9% versus 19% respectively 3
- Clipping achieves higher rates of complete aneurysm occlusion (81.4% vs 57.5%) 6
- However, clipping causes more frequent neurologic deficits (22% vs 12%) and longer hospitalizations (48% vs 8% staying >5 days) 3
If You Mean Pulmonary Artery Catheterization:
- PA catheters are not recommended for routine use but may be reasonable for severe valvular disease, decompensated heart failure, or cardiogenic shock when non-invasive assessment is inadequate 4
- Complications include arrhythmias, venous thrombosis, pulmonary embolism, catheter infections, and pulmonary artery rupture 4
If You Mean Temporary Vascular Clipping During Surgery:
- Temporary clips are used during neurovascular surgery (for AVMs or aneurysms) to control bleeding and facilitate dissection 7
- This is a surgical technique, not a definitive treatment
