Percutaneous transluminal angioplasty for renovascular hypertension in a neonate.

AIM

To report on the first case of successful percutaneous transluminal renal artery angioplasty in a neonate.

CASE REPORT

a 5-d-old neonate was admitted with cardiorespiratory failure. Monitoring of blood pressure revealed severe arterial hypertension. Doppler sonography detected stenotic flow in the right renal artery. A (99m)Tc-MAG3 scan revealed highly diminished elimination by the right kidney. Selective renin levels were 23,968 ng/l in the right and 3770 ng/l in the left renal vein and the aorta. Percutaneous transluminal angioplasty using a 2 x 10 mm balloon catheter was performed on the 8th day of life.

RESULTS

The patient was discharged from hospital normotensive without anti-hypertensive medication. During 8 mo follow-up the blood pressure remained normal, Doppler sonography revealed no recurrent artery stenosis, and renal function improved.

CONCLUSION

Neonatal percutaneous transluminal angioplasty for renal artery stenosis may be feasible in selected patients.
