Endovascular treatment of thoracic aorta aneurysm and dissection

Full text: The aim is to give up to date information about modern endovascular treatment of aortic pathology Dissection and aneurysms of the aorta are life threatening condition requiring in most of the cases prompt surgical or endovascular treatment because of the poor natural evolution. Purpose: to assess the immediate and 1-year outcome of endovascular treatment in broad spectrum of acute and subacute aortic syndrome during the last 3 years (November 2012 - August 2015) in City Clinic (Sofia, Bulgaria). We performed endovascular treatment of 47 patients (43 men, 4 women) at average age 54 y. with dissection (24) and aneurysms (23) of the aortic arch and thoracic aorta (in 5 emergent treatment was performed for aortic rupture). All patients were treated with minimal surgical femoral approach. In 4 (9%) of them initial carotid to carotid bypass was performed in order to provide a sufficient landing zone for the endograft implantation.the last 9 patients (19%) were treated without general anesthesia with either deep sedation or epidural anesthesia. Results: In all patients successful endograft implantation was achieved. Additional stent-graft or open cell stent was implanted in 4 cases in order to centralize the flow in the compressed true lumen. In 5 cases additional vascular plug or large coil was delivered in the left subclavian arteryostium in order to interrupt retrograde aneurysm or false lumen filling. Complications: 30 days mortality-2.2%, neurologic disorders (4.4%). one year survival- 45 (90.5%). 3 and 6 mo control CT scan showed no migration of the graft in 100%, full false lumen isolation in 19 out of 24 dissections (80%) and aneurysm free of expansion in 20 out of 23 (86%), patent carotid bay-pass graft in 4 of 4 (100%). This one center study showed excellent immediate and 1 year clinical and device results from endovascular repair of potentially fatal disease. Endovascular treatment is a method of choice for broad spectrum of aortic pathology involving the arch and descending aorta. Endovascular treatment is a minimally invasive modern approach receiving higher level of evidence and indication class IB in the last clinical guidelines of the ESC
