What is Debranching of aortic arch?
Type I hybrid debranching: a dacron graft is directly sutured onto the ascending aorta using a partial clamping without the need for ECC, from which all the branches to SAT arise, with or without revascularization of the LSA.
What is hybrid TEVAR?
The hybrid thoracic endovascular aortic repair (TEVAR) approach combining techniques of arch and viscero-renal artery debranching or translocation with subsequent endovascular repair of the aneurysm has emerged as a potential tool to extend the envelope of intervention in those patients with a poor physiological …
What is the difference between TEVAR and Evar?
EVAR patients were more likely to have wound complications (1.7% vs 7.6%, P . 031), whereas TEVAR patients had a higher incidence of neurologic (10.7% vs 0.9%, P . 001) and pulmonary complications (5.8% vs 1.8%, P .
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 a Debranching procedure?
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 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 long is recovery from aortic aneurysm stent surgery?
You may feel more tired than usual for 1 to 2 weeks after surgery. You may be able to do many of your usual activities after 1 to 2 weeks. But you will probably need up to 4 weeks to fully recover.
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.
What is a Fevar procedure?
Fenestrated Endovascular Aortic Repair, also known as FEVAR, is a minimally invasive procedure that allows surgeons to repair the aorta through small incisions in your groin and or arms while still preserving blood flow to the critical branch arteries to your kidneys and other organs.
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.
How long does it take to debranch a Tevar?
Three patients underwent simple TEVAR and six underwent debranching TEVAR (LSCA occlusion + left common carotid artery to LSCA bypass). Median operation time was 108 (75-157) min for simple TEVAR and 177 (112-218) min for debranching TEVAR.
Is debranching Tevar appropriate for btai in multiple trauma patients?
Conclusion: Despite debranching TEVAR taking approximately 60 min longer than simple TEVAR, short-term results indicated it to be acceptable for BTAI in multiple trauma patients to avoid LSCA complications unless we fail to stop bleeding first.
What is the average operation time for a Tevar fracture?
Median operation time was 108 (75-157) min for simple TEVAR and 177 (112-218) min for debranching TEVAR. Concomitant injuries included intracranial hemorrhage (N = 1), intra-abdominal injuries (N = 3), pneumo- or hemothoraxes (N = 4) and pelvic/extremities fractures (N = 7).
