  Abstract 


Alagille syndrome (ALGS) is a complex multisystem genetic disorder. Patients with ALGS usually require liver transplantation (LT). Congenital heart diseases are also common in ALGS patients. ALGS patients may become ineligible for LT procedure due to cardiac abnormalities whereas any corrective cardiac surgeries are precluded due to the Child C cirrhosis of the liver in these patients. We report a unique case of a 4-year- and 10-month-old girl who underwent open-heart surgery and living donor liver transplantation (LDLT). She had significant hepatic and cardiopulmonary involvement, and Child C cirrhosis with portal hypertension and complex cardiac defects, and was ineligible for up-front LT. An open-cardiac surgery was performed and after 12 h she received LDLT using a left lateral hepatic graft. This is the first report of a case of successful combined open-heart surgery and LDLT in a child with ALGS with cardiac defects and Child C liver cirrhosis.

  Introduction Top


Alagille syndrome (ALGS) is a multisystem disorder which generally occurs due to defective Notch signaling pathways.[1] A majority of ALGS patients are diagnosed within the 1st year of life.[2] The progressive liver disease with cholestasis and pruritus usually seen, require consideration for liver transplantation (LT).[3] Congenital heart diseases are also common in ALGS patients.[4] We report a unique case of a girl child with ALGS who underwent open-heart surgery and living donor liver transplantation (LDLT).


  Case Report Top


A 4-year- and 10-month-old girl presented with a diagnosis of ALGS. She had jaundice, pruritus, ascites, generalized weakness, poor appetite, average nutritional and performance status, significant hepatic and metabolic bone diseases, cardiopulmonary involvement, and Child C cirrhosis with portal hypertension.

Her laboratory investigations were – hemoglobin: 8.9 g/dL, international normalized ratio (INR): 4.98, total bilirubin: 14 mg/dL, direct bilirubin: 1.8 mg/dL, serum glutamic-oxaloacetic transaminase (SGOT): 82 IU/L, serum glutamic-pyruvic transaminase (SGPT): 110 IU/L, gamma-glutamyl transferase (GGT): 252 IU/L, total protein: 6.1 g/dL, and albumin: 3.1 g/dL. Autoimmune and virology markers were negative, thus ruling out the autoimmune liver disease and any active or past infection. Wilson's disease was ruled out with ceruloplasmin level of 0.4 g/dL, and hereditary hemochromatosis with normal serum iron (120 μg/dL) and ferritin (400 pmol/L) levels. The patient also had metabolic bone disease (rickets) with low calcium (6.5 mg/dL), high-alkaline phosphatase (ALP, 214 IU/L) and urea (32 mg/dL), and severe growth retardation and delayed motor developmental milestones. Her liver and bone abnormalities were indicative for LT.

Cardiac evaluation through transthoracic echocardiogram showed severe supravalvular pulmonary stenosis (PS) with narrowing in the main pulmonary artery (MPA), moderate left pulmonary artery (LPA) stenosis, small perimembranous ventricular septal defect (VSD) of 1.5 mm diameter, small apical VSD of 2.5 mm diameter, and a small patent ductus arteriosus (PDA). The severe supravalvular PS increased the peak velocity of flow across the pulmonary valve/MPA with a transpulmonary pressure gradient of 112 mmHg, eventually leading to bidirectional shunts across the VSDs. These features made her ineligible for an upfront high-risk procedure, i.e., liver transplant. Hence, an initial plan was made to correct the supravalvular PS with balloon valvuloplasty by a multidisciplinary team.

Desired outcomes were not achieved by balloon angioplasty of supravalvular PS as the transpulmonary pressure gradient was 100 mmHg postprocedure. Hence, a combined open-heart surgery (MPA and LPA plasty) followed by LDLT was planned. Five days later, open-heart surgery was performed where MPA and LPA stenosis were repaired with pericardial patches. Increased central venous pressure was noted 6 h postoperatively, and a repeat echocardiogram showed pericardial effusion. The surgical wound was reexplored, and reactionary hemorrhage was noted from the site of sternal wires. Bleeding was controlled and the sternal wound was left open to be closed after liver transplant surgery. Within 12 h of the initial surgery, ABO-compatible (B+ to AB+) LDLT surgery commenced.

Her 32-year-old mother donated her left lateral hepatic lobe. Hepatic vein reconstruction was performed by quilt venoplasty using a donor graft vein. The graft-to-recipient weight ratio was 3. Solumedrol 50 mg was used as induction immunosuppression. Piperacillin-tazobactam, teicoplanin and fluconazole were antimicrobials used at induction. On exploration of the recipient, ascites and splenomegaly were observed. Native hepatectomy was performed and orthotopic liver transplant along with biliary reconstruction by Roux-en-Y hepaticojejunostomy and sternal wound closure were completed within 24 h from commencing the open-heart surgery. The Piggyback technique was performed.

There were no immediate postoperative complications. The patient was weaned off the ventilator on postoperative day 3 while inotropic support discontinued on postoperative day 6. Persistent inhalational oxygen was required for 10 more days after extubation. The patient was discharged on postoperative day 14 without any pertinent issues, while on maintenance immunosuppression with tacrolimus, mycophenolate mofetil (MMF), and wysolone. At discharge, her blood levels were as follows: hemoglobin − 12 g/dl, INR − 1.2, platelets − 160,000/mL, total bilirubin − 1.4 mg/dL, SGOT − 41 IU/L, SGPT − 92 IU/L, ALP − 131 IU/L, GGT − 103 IU/L, urea − 38 mg/dL, and creatinine − 0.22 mg/dL.

Steroids were withdrawn at 5 months posttransplant. Valganciclovir was continued until 1-year posttransplant, as donor was cytomegalovirus (CMV) immunoglobulin G (IgG) positive and the recipient was CMV IgG negative. Prophylactic antifungals, trimethoprim/sulfamethoxazole, and supplementation with calcium and multivitamins were continued until 1-year posttransplant. She was subsequently weaned off MMF at 17 months posttransplant.

At her last follow-up, 5 years after her transplant, she was on tacrolimus monotherapy maintenance. Her liver graft function was stable with total bilirubin: 0.47 mg/dL, SGOT: 28 IU/L, SGPT: 54 IU/L, ALP: 301 IU/L, and GGT: 22 IU/L. There we no episodes of liver graft rejection or infections.


  Discussion Top


To our knowledge, this is the first reported case of a combined open-heart surgery (MPA and LPA plasty along with the closure of VSDs and pulmonary valve replacement) and LDLT in a 4-year- and 10-month-old girl suffering from ALGS, and followed-up for 5 years posttransplant.

The greater percentage of surgical complications and reoperations are observed in patients undergoing LT for ALGS when compared to other surgeries performed for biliary atresia (BA).[5] Histological and imaging findings should be considered to differentiate ALGS and BA.[5],[6] Renal disease, although not a feature in our patient, is seen in about 40% of patients with ALGS.[7]

As ALGS is an autosomal dominant hereditary disorder, with variable penetrance, donors of the patient with ALGS may present without any symptoms. Bile duct paucity must be ruled out in these donors.[8] Living donors must either undergo a liver biopsy or molecular genetic testing to rule out ALGS genetic mutations.

There have been reports of combined heart-lung-LT in a pediatric patient from a deceased donor.[9] Other reports suggest that LDLT were performed in 20 patients with ALGS, but none of them underwent heart surgery to correct any defect before transplant.[6] Furthermore, reported are cases of two patients with ALGS who underwent open-heart surgery, but without combined liver transplant.[4]

In conclusion, to our knowledge, this is the first reported case of a successful combined open-heart surgery and LDLT performed in a child with ALGS. The diagnosis of ALGS is challenging and can be easily misdiagnosed as other cholestatic diseases. Perioperative and long-term management of ALGS can be particularly challenging. Successful outcomes can be achieved by multidisciplinary involvement with expertise in handling complicated conditions.
