Tóm tắt

Nghiên cứu hồi cứu 39 bệnh nhân mắc bệnh van hai lá đã có biến chứng nhồi máu não được phẫu thuật tại Khoa Phẫu Thuật Tim Bệnh viện Nhân Dân Gia Định từ tháng 4/2013 đến tháng 12/2017. Tuổi trung bình 50,3 ± 7,56, thời gian mắc nhồi máu não 8,2 ± 11,2 tháng, NYHA II và III-IV lần lượt là 38,5% và 10,3%. Yếu liệt chi chiếm 83,8%, liệt 0/5 chiếm 39,8%. Rung nhĩ gặp 88,2%, chỉ số tim-ngực là 0,58 ± 0,08, BNP 1989 ± 1156 pg/ml. Hẹp hai lá 94,8%, hở hai lá 48,7%, huyết khối buồng tim 28,2%, diện tích van 0,7 ± 0,19 cm², LA: 53,6 ± 7,9 mm, LVDd: 41,3 ± 3,6 mm, PAPs: 66,5 ± 17,8 mmHg. Tổn thương não bán cấp hay mãn (MSCT hoặc MRI) gặp 100%. Thời gian tuần hoàn ngoài cơ thể 83,18 ± 15,65 phút, thời gian cặp ĐMC 50,53 ± 11,15 phút, thời gian thông khí cơ học 11,52 ± 6,12 giờ, thời gian hồi sức sau mổ 69,74 ± 31,54 giờ. Tai biến thường gặp sau mổ là cơn nhịp nhanh thất (12,8%) và động kinh cục bộ gặp 15,4%, Không xuất hiện tai biến mạch máu não sau mổ, không có trường hợp nào tử vong.
