Dr Liu has been excellent in all kinds of aortic diseases such as acute aortic dissection, coronary artery bypass graft (CABG) in treating coronary artery disease and acute myocardial infarction, modified Maze procedure in ablation of atrial fibrillation, valve replacement and valvuloplasty, minimally invasive cardiac surgery, cardiac trauma, correction of various complex congenital heart diseases and surgical treatment of other common congenital and acquired cardiac diseases. He took the lead in carrying out surgical treatment of aortic diseases in the Northeast of China in 2005, especially in the surgical treatment of acute aortic dissection. Since 2009, professor Kexiang Liu has been devoting lots of efforts to the modifications of treatment of Stanford A aortic dissection, thus creating a novel technique. This novel modified surgical method not only reduces the blood loss, shortens operative time, but also improves the success rate of the surgery, simplifies the complexities of the traditional surgery patterns. The innovations of “Modified Stented-Graft” and “Stented-graft with Artificial Vascular Prothesis ” both obtained national patent. New Progress has been made remarkably since 2016 in the field that more than 50.8% of the aortic dissection surgeries have been performed without blood transfusions.Being the first to carry out independent coronary artery bypass graft (CABG) surgeries in Jilin Province, more than 95% are off-pump and the successful rate reaches more than 99% and the rate of no blood transfusion has reached 93%. Professor Kexiang Liu took the lead in performing hybrid operations containing multiple valve replacement, CABG and surgical ablation of atrial fibrillation. He has been promoting the use of autologous blood recovery technology and almost 73% of the operations are without blood transfusions.
Description
Methods: Eighty-eight patients (9 with Marfan syndrome), including 69 males (78.4%) and 19 females (21.6%), underwent aortic root replacement using the modified Bentall technique from 2011 to 2020 at our hospital. The patients' mean age was 43.4±11.7 years (range, 20–71 years). Data were collected on surgical time, aortic clamping time, cardiopulmonary bypass time, and computed tomography angiography before discharge.
Results: The patients' in-hospital mortality was 2.27%, with one case of multiple organ dysfunction syndrome and one of arrhythmia. The mean aortic cross-clamp time and cardiopulmonary bypass time were 120.9±27.1 mins and 159.2±37.9 mins, respectively. The follow-up rate was 94.2% (81/86) for 55±23 months (range, 6–120). Follow-up mortality occurred in three cases (3.7%), including one death due to a traffic accident, one death due to cerebral hemorrhage, and one sudden death of unknown reasons. No patients required aortic root re-operation during follow-up. The survival rate was 98.8%, 95.9%, and 95.9% after 48, 96, and 120 months, respectively.
Conclusions: Our modified Bentall technique can be performed easily and safely, with excellent middle- and long-term outcomes. Our technique can be an effective alternative method in aortic root aneurysm treatment.
