What is debranching of aorta?
The term “partial debranching” refers to operations with revascularization of just the left carotid artery and subclavian artery, i.e. by carotid-carotid bypass whereas “total debranching” also includes revascularization of the brachiocephalic trunk.
What is the tevar procedure?
Thoracic endovascular aortic repair (TEVAR) is a procedure to treat an aneurysm in the upper part of your aorta. The aorta is your body’s largest artery. An aneurysm is a weak, bulging area in the aorta wall. If it bursts (ruptures), it can be deadly. TEVAR is a minimally invasive surgery.
What is endovascular Debranching?
Conclusion: Endovascular debranching permits planned extension of the thoracic endograft over arch vessels while further minimizing the need for open reconstruction. Short-term results indicate technical feasibility of this approach.
What is frozen elephant technique FET?
The frozen elephant trunk (FET) procedure, or open stent grafting, is a tool for the combined open and endovascular treatment via a median sternotomy of extensive aortic disease involving both aortic arch and descending thoracic aorta.
How serious is AAA surgery?
But this surgery has serious risks during surgery and soon after surgery. About 5 out of 100 people die during surgery or within 30 days. This risk may depend on your health before surgery and where the aneurysm is located. About 9 to 17 out of 100 people have complications during the surgery or within 30 days.
HOW LONG DOES A aortic stent last?
Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.
How long is TEVAR procedure?
Depending on the type of disease, the TEVAR procedure usually provides a cure. The procedure usually takes around 2 hours to complete. The alternative to TEVAR is what doctors refer to as “open repair”.
Where is the innominate artery?
mediastinum
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck. It is the first branch of the aortic arch.
What is an elephant trunk procedure?
The elephant trunk procedure is a two-stage procedure used to treat extensive aneurysms involving both the ascending aorta and aortic arch, and the descending thoracic or thoracoabdominal aorta.
Why is it called frozen elephant trunk procedure?
The so-called ‘frozen elephant trunk’ technique is adapted from the classical elephant trunk technique first described by H.G. Borst in 1983 and allows the repair of concomitant aortic arch and proximal descending aortic aneurysms in a single stage.
