Citation preview
Management of Patent Dactus
ArteriosusPresented by
Dr. Paul Shubhra Prakash
There are 3 options for the treatment of PDA:
• Medical management
• Catheter based procedure
• Surgery
Aims of treatment:• To treat or prevent Heart failure.
• To prevent infective endocarditis.
• To prevent development of
pulmonary vascular disease.
Medical management:1. Conservative management: a. Fluid restriction b. Diuretic theraphy c. Adequate calorie d. Ventilator support 2. Drugs: Indomethacin Ibuprofen
Indications of drugs:Prophylactic: Dose: 0.1 mg/kg/dose 24 hourly for 6
daysTiming: usually within 1st 24 hours of
life.Indication: All infant <1250gm birth
weight who have respiratory distress.
Therapeutic: Timing: usually within 1st 14 days of life.
Indications:
1. If there is any clinical sign of PDA In preterm baby.
2.There are signs of overt failure or congestive cardic failure.
3. Re-treatment after failure of the first course indomethacin
4. Rcurrence of PDA after first course of indomethacin
Dose of Indomethacin: O.2mg/kg stat followed by
<7days and birth weight <1250gm
0.1 mg/kg/dose 12 hourly for 2 doses
>7days and birth weight >1250gm
0.2 mg/kg/dose 12 hourly for 2 doses
Adverse effect: Renal dysfunction Gastro-Intestinal bleeding Thrombocytopenia Periventricular Leucomalasia
Contra-indication: Serum creatinine>1.8 mg/dl Renal or Gastrointestinal bleeding NEC Sepsis
Dose of Ibuprofen:
Initial dose of 10mg/kg followed at 24 hour intervals by two doses of 5mg/kg.
As Ibuprofen has less Adverse effect than Indomethacin, So Ibuprofen is superior than Indomethacin.
Catheter-based
Procedures:
Timing: usually done after
neonatal period
Indications:1. Small PDA with intra vascular coils.
2. Moderate to Large PDA with a catheter
introduced sac into which several coils
are released or with an umbrella-like
device.
Device used in Catheter-Based Procedures:
Catheter procedure:• Sedation
• A small incision is given in the inner thigh
• A long, thin, flexible, hollow tube is inserted through the femoral vein
• Implantation of device to PDA through tube.
Catheter based procedure:
Catheter based procedure:
Surgery:Indications:• A Premature or Full-term infant with symptomatic heart failure from the PDA in whom medical treatment has failed or in whom there is a contraindication to the use of drugs. • A PDA isn’t successfully closed by a Catheter-based Procedure.• Surgery is planned for treatment of related Congenital heart defects.
Timing: Usually after 6 months of
age.
Procedure: Ligation and division of ductus via a
Thoracotomy.
Complications: Bleeding
Pneumothorax
Chylothorax
Infection
Thoracic scoliosis
Surgical repair of PDA:
Surgery of PDA
