RESUMEN
The results of PTRA in treatment of renovascular hypertension in four children aged 5, 7, 13 and 15 are presented. All patients suffered from severe hypertension. Tests showed all of them to have fibromuscular dysplasia stenosis of the main renal artery and significant lateralization of renin levels. One suffered from associated polycystosis of kidneys and in another the renal artery stenosis was bilateral. In all patients successful patency was achieved. In one patient, the arterial pressure after PTRA was normalized, while in the others it was considerably improved. Two patients, tested 8 and 12 months after PTRA, were lost to further follow-up. In one of the remaining two, stenosis and hypertension reappeared 5 years after PTRA. After autotransplantation the patient was normotensive. In the other, also 5 years later, recurrent hypertension appeared related to the associated polycystosis.

Developmental abnormalities in the embryo may lead to tumours in the sacro-coccygeal area, so-called sacral cysts and the teratomas (5, 7). At birth they are caudal tumours of variable size covered with thin, stretched skin. Blood vessels can be seen through the skin, particularly in the mid-line. One gains the impression that the stretched skin could burst at any moment. It is assumed that these teratomas derive from the pluripotent cells of Hensen's node and then grow in front of the coccyx (2). They grow and spread in various directions, particularly in a dorsal and caudal direction extra-rectally and, to a lesser extent, into the pelvis in a pre-sacral position. The classification of these tumours depends on their spread. The spread and localisation of these tumours may cause stenosis of elongation of the rectum and displacement of small and large bowel and of the bladder.
