RESUMO
We report a case of aortic regurgitation (AR), coronary artery-to-pulmonary artery (CAPA) fistula, pulmonary atresia with ventricular septal defect (PA/VSD), and major aortopulmonary collateral arteries (MAPCAS). As a result of coronary steal and AR, myocardial ischemia and ventricular dysfunction occurred. When the patient was 2 months old with a body weight of 2.7 kg, we performed fistula ligation, aortic valvuloplasty, unifocalization of the MAPCAS, and right ventricle-to-pulmonary artery shunting. After the operation, the AR volume reduced, and the patient was scheduled for repair.

The use of an epicardial pacing lead may be essential in pediatric patients with rhythm disturbances. In patients with single-ventricle physiology who need scheduled multistage operations, the lead could be an obstacle because of the induction of tight adhesions and the need for dissection in the next operation. We propose a novel reproducible technique for the placement of an epicardial pacing lead followed by easy dissection of the entire length of the lead in the next operation in neonates or young infants who need multistage operations.

A 70-year-old man underwent graft replacement for infrarenal abdominal aortic aneurysm, 50 mm in diameter. Postoperatively, he suffered from bilateral lower extremital ischemia. Although he underwent emergency embolectomy of both legs under general anesthesia, severe purplish discoloration of the distal lower extremities developed, and acute renal dysfunction occurred. He was diagnosed with cholesterol crystal embolization syndrome (CCE). We initiated intravenous steroid therapy and infused prostagrandin intraarterially and conducted low density lipoprotein (LDL) apheresis. However, his renal function did not improve and his bilateral toes became necrotic completely. Multiple organ failure rapidly worsened and he died at 38 days after surgery. CCE complicated with severe renal dysfunction is a lethal iatrogenic complication after surgery for abdominal aortic aneurysm. Because the number of CCE is likely to increase in the near future, we should study about CCE more seriously.
