Introduction: Internal bleeding still remains a serious condition, which must be urgently diagnosed and treated. In the Faculty Hospital in Hradec Králové the diagnosis of the internal bleeding source and its consequent treatment is managed under cooperation between a surgeon and an interventional radiologist. A Case-Review: In the case-review section of this report, a total number of five patients with serious cases of internal bleeding, the source of which was diagnosed and treated under cooperation between the above mentioned specialists is presented. The patients concerned suffered from the following: a trauma to the liver parenchyma, posttraumatic arterioportal shunts, an intraheparic aneurysm, a relaps of the uterine carcinoma with hemorrhaging into the colon and the vagina, bleeding into retroperitoneum. In all the cases the lesion was successfully treated and the hemorrhage was managed. Discussion: Exact location of the bleeding artery during an arteriogragraphic examination is a prerequisite of a successful treatment of the condition. Both, the absorbable materials which allow gradual recanalization of theembolized vessel, and the non-absorbable materials may be used to conductembolization of the affected vessel. It is necessary to haemodynamically stabilize the patient prior to the procedure. Conclusion: In many cases, the cooperation between a surgeon and an interventional radiologist allows for the source of the internal bleeding to be located and managed. It is indicated in certain cases of benign and malignant disorders and in some cases of the parenchymatose organs trauma.
