aortic fenestration
A surgical procedure creating an opening between the true and false lumens in aortic dissection. Used to equalize pressures and reduce malperfusion.
Full Definition
Aortic fenestration is a surgical technique involving the creation of a controlled communication between the true and false lumens in cases of aortic dissection. This procedure helps to decompress the false lumen and restore flow to compromised branch vessels. It can be performed either surgically through direct visualization or percutaneously using balloon techniques. The fenestration equalizes pressures between the lumens and can be life-saving in acute malperfusion scenarios. This technique is particularly valuable when endovascular or open surgical repair is not immediately feasible.
Usage
Usage note: Often abbreviated as 'fenestration' in context, but specify 'aortic' for clarity in mixed surgical reports.
