An 8-day-old male child, born at 38th gestational weeks, weighing 3.2 kg was referred to our institute with provisional diagnosis of intestinal obstruction as suggested by abdominal ultrasound. Physical examination of child revealed tachypnea, heart rate 160 bpm, blood pressure of 68/48 mmHg, and pulse oximetry reading 98% with 2 L O2. Emergency laparotomy was planned under general anesthesia and caudal analgesia. Preoperative hemogram, renal function test, liver function test, serum electrolytes, and arterial blood gas (ABG) analysis were normal. Chest X-ray (CXR) revealed normal cardiac size. General anesthesia was induced with intravenous ketamine 3.2 mg, inhalation of sevoflurane 8% with oxygen, and atracurium followed by orotracheal intubation. Caudal analgesia was given with 3.2 cc of 0.1% bupivacaine with sterile technique. Anesthesia was maintained with 100% oxygen (as air not available at our institute), isoflurane, and incremental dose of fentanyl and atracurium. Intraoperatively, small intestinal duplication cyst was noted with evidence of obstruction. Excision of cyst was performed followed by resection of bowel and stoma. Vital signs remained stable intraoperatively. A volume of 45 ml blood loss was replaced with whole blood and 1% dextrose ringer lactate was used for maintenance and replacement of evaporative losses. Postextubation, the neonate was maintaining his expiratory blast, heart rate, and reflex activity and was given oxygen by nasal prongs at 2 lit/min. On postoperative 2nd day, neonate developed tachypnea and chest indrawing required nasal continuous positive airway pressure with oxygen 5 L/min and pressure 5 cm H2O. Heart rate and blood pressure were 173/min and 70/50 mmHg, respectively. CXR, ABG, and abdominal ultrasound were done and were normal. Hemoglobin, metabolic screening, and serum electrolytes were normal. Analgesia was given with intravenous paracetamol 30 mg three times a day. Two-dimensional echocardiography was advised by pediatrician in view of persistent chest indrawing. Echocardiography revealed nonobstructive cardiac total anomalous pulmonary venous connection (TAPVC) with four pulmonary veins draining into coronary sinus, small 3-mm ostium secundum defect with right-to-left shunt, severe pulmonary hypertension (55 mmHg), and normal systemic venous drainage with right atrial and ventricular dilatation. Cardiothoracic opinion was sought for same and they advised intracardiac repair. We lost follow-up after referral as patient's relative took discharge against medical advice.
Respiratory distress is a common problem in neonates and causes may be respiratory, cardiovascular, central, metabolic, hematological, and surgical. TAPVC represents 1% of congenital heart disease in which pulmonary veins drain into the right atrium either directly or indirectly. Based on connection, they are divided into four types: supracardiac (50%) draining into innominate vein, infra diaphragmatic (20%) draining into hepatic and portal vein, cardiac (20%) draining into coronary sinus, and mixed (10%) is combination of any of type. Various associated congenital malformation seen with TAPVC are asplenia, polysplenia, midline liver, and intestinal malrotation. Patients with TAPVC with obstruction present with progressive cyanosis and respiratory distress soon after birth. Patients with TAPVC without pulmonary venous obstruction are usually asymptomatic at birth (as in our case), but at least 50% become symptomatic within 1st month of life. Clinical presentation depends on the degree of pulmonary venous obstruction and extent of mixing of blood between right and left atrium. Here, the autism spectrum disorder allows the free communication between two atria and mixing of the venous blood. Postnatal decrease in pulmonary vascular resistance along with significantly decreased left side compliance promotes the delivery of mixed systemic and pulmonary venous blood to pulmonary circuit. Further increase in pulmonary blood flow can be seen with perioperative fluid shifts due to intestinal surgery and vigorous intravenous fluid therapy which could have happened in our patient. Excessive pulmonary blood flow can result in pulmonary hypertension or may progress to pulmonary edema. This increases the work of breathing and hence appearance of tachypnea and persistent chest indrawing. This explains the delayed presentation of TAPVC in our neonate, although the condition was present since birth.
