[Embolization of iatrogenic traumatic vascular lesions of the kidney. Apropos of 25 cases].

The authors present 25 cases of traumatic iatrogenic vascular lesions of the kidney, treated by embolization. Twenty two patients were seen for serious haemorrhagic complications: the embolization restored haemostasis in all cases. An early precocious relapse, due essentially to the use of reabsorbable embolization material, was seen in 4 patients, 2 of which were able to be reembolized, thereby definitely stopping the haemorrhage. No immediate complications were noted. 5 of the 12 patients follow-up, showed signs suggestive of infarction, strictly localized to the corresponding segmental territory embolized. The use of inflatable balloons facilitates the catheterization of segmental renal arteries and the endovascular treatment. Therapeutic angiography offers a simple, efficient, and remarkably conservative treatment of vascular iatrogenic trauma of the kidney. Angiography defines the number, site and type of vascular lesions ; the embolization assures the elective treatment.
