Hematuria incoercible en poliquistosis renal: tratamiento exitoso mediante embolización arterial superselectiva incoercible / Hematuria in polycystic kidney disease: successful treatment using superselective artery embolization

Se presenta el caso de un paciente de 81 años de edad, con riñones poliquísticos de gran tamaño, enfermedad renal crónica en estadío 3, y un quiste polar derecho sangrante que provocaba severa anemización. Previa aplicación de un protocolo de nefroprotección, se cateterizó la arteria renal derecha, accediéndose al ramo polar inferior de la arteria retropiélica e identificando angiográficamente el sitio de sangrado; desde este punto se realizó la embolización arterial superselectiva con fragmentos de Spongostan. Finalizado el procedimiento, se comprobó la interrupción del sangrado luego de dos horas y el examen del sedimento urinario a los noventa días de seguimiento, mostraba entre 6 a 10 hematíes por campo. Se discute el rol de la red vascular en poliquistosis, la expansión celular en la pared quística, y la provocación de isquemia mediante tratamiento intervencionista ultraselectivo, a fin de preservar la función renal y prevenir complicaciones.

A patient of 81 years old, with oversized polycystic kidneys, chronic kidney disease in stage 3, and a bleeding right polar cyst, that caused severe anemia, is presented. First, a nephroprotective protocol was applied. Then, the right renal artery was catheterized, accessing the polar lower branch of the retro-pyelic artery and angiographically identified the bleeding area, and the superselective arterial embolization was performed with fragments of Spongostan. When the procedure concluded, the stopping of the bleeding was proved after two hours. The urinary sediment examination after ninety days of monitoring showed between 6 and 10 red cells per field. The function of the vascular network in polycystic disease, the cell expansion in the cyst wall, and the induced ischemia through the ultraselective interventionist treatment, is discussed in order to preserve kidney function and prevent any complications.

Problems in superselective angiography and embolization for acute hemorrhagic lesions / 介入放射学杂志

Superselective angiography and embolization is one of the important methods in the management of acute hemorrhage, providing mini-invasion and high efficacy, etc. The implication of angiography and embolization on bleeding were reviewed and the embolic agents as well as the interventional procedures were commented in this article.
