Popis: | We previously reported a unique technique called “less invasive quick replacement (LIQR)” for treating type A acute aortic dissection with moderate hypothermic arrest (28 °C). This study examines the modified LIQR using mild hypothermic arrest (30 °C) with partial retrograde cerebral perfusion (RCP). 187 patients were divided into 2 groups: group L consisted of 130 patients underwent LIQR without any cerebral perfusion; group M consisted of 57 patients who were treated with modified LIQR. In modified LIQR, circulatory arrest was commenced under the 30 °C for open distal aortic stamp fixation. RCP was used during final half anastomosis of the prosthesis and then rapid re-warming was initiated. The incidence of additional valve or coronary surgeries was significantly higher in group M (28.1%) than in group L (9.2%). The average rectal temperature was significantly higher in group M (29.5 °C) than in group L (27.4 °C). The durations of brain ischemia (M 7.7 min; L 18.6 min), cardiopulmonary bypass (M 82.0 min; L 93.3 min), and overall operation (M 145.2 min; L 154.2 min) were significantly shorter in group M. The incidence of postoperative brain damage was 6 patients (4.6%) in group L, but none in group M. The hospital mortality rate was 3 patients in group L (2.3%). All group M patients were discharged from the hospital without any complications. Modified LIQR is safe and effective. It makes the surgery much quicker and is a less invasive procedure. The surgical outcome was also favorable. |
