Kết quả sớm 46 bệnh nhân được phẫu thuật Bi-directional Glenn tại Trung tâm tim mạch - Bệnh viện E

Abstract

Objective: Evaluating the soon results in 46
patients after bidirectional Glenn shunts (BDGS)
operation at the Cardio-vascular Center - E
Hospital.
Subjects and Methods: Retrospective,
prospective and descriptive study of 46 patients
who had undergone bidirectional Glenn shunts
operation at the Cardio-vascular Center - E
hospital from 6/2011 - 7/2013.
Results: The mean age was 6 ± 1years (6
months - 21 years). The average weight was 15.6
± 2kg (5kg - 43kg). All patients had moderate to
severe cyanosis, the average arterial blood
oxygen saturation was 71.8% ± 1.5% (50% -
82%). 3 patients had artery-pulmonary bypass
before. Cardiopulmonary bypass was used in 45
patients, 1 patient, without cardiopulmonary
bypass. 16 patients had bilateral BDGS, 30 patients had BDGS, 3 patients with BlalockTaussig shunt interruption. Postoperative superior
vena cava pressure averaged 16.5±2.6 mmHg
(14-24). All patients used postoperative
pulmonary vasodilator. Arterial blood oxygen
saturation after surgery compared with before
surgery:14±0.6% (statistical significance at p
<0.05). Mortality rate was 4.3%. The average
duration of mechanical ventilation: 47.1±2.8
hours (0.3 - 72), length of stay in intensive care:
5.6±1.2 days (2-30), length of hospital stay:
16±2days (2-64). 44/46 patients discharged from
the hospital with significant improvement in
clinical and blood oxygen saturation. 5 patients
under-went a subsequent Fontan.
Conclusions: BDGS operation is considered
to be intermediate stages in the strategy repaired
congenital heart defect with univentricular
preparation for Fontan operation. It is done as a
first or second stage after artery-pulmonary bypass
or pulmonary artery Banding procedure. Our study
shows that a relatively positive early results for
patients with Glenn operation in our Center.
