What should renal arteriography do?

summary

The kidney is the most important excretory organ of the human body. If the kidney function is not good, there will be a lot of complications. Let me share my experience with you and teach you how to do this kind of operation. Hope to help you.

What should renal arteriography do?

First: abdominal aortography: the basic method and procedure are the same as that of embolization for renal cell carcinoma, but the head end of the angiography catheter should not be lower than that of the thoracic aorta to avoid the omission of accessory renal artery.

Second: superselective angiography of renal artery: superselective angiography of target vessel by changing catheter, to determine the location, scope and vascular anatomy of bleeding artery, and to formulate treatment plan. The angiographic findings of acute renal hemorrhage were as follows: the renal branches were interrupted or absent, and the branches were reduced; Irregular peripheral blood vessels, extravasation of contrast media or traumatic pseudoaneurysmal changes were found; The laceration area showed irregular strip defect or renal parenchyma separation; In severe contusion and laceration, the size and shape of the renal tissue cleft or the renal pole blood vessels connected with the large blood vessels could be shown in its substantive phase, and its edge was rough and irregular; The density of renal pole laceration area decreased or did not develop; In the parenchymal phase, the contour of kidney was deformed; Arteriovenous fistula; Subcapsular hematoma displaces or dilates the encapsulated artery

Third: renal artery embolization: superselective catheterization of target vessels. Gelatin sponge particles or PVA particles were dissolved in normal saline, and an appropriate amount of contrast agent was added. Under TV monitoring, the embolic agent was slowly injected according to the volume of embolic vessels. The disappearance of arterial branches in the lesion area and the retention of contrast medium in the vessel or injured area for a long time indicate the success of embolization.
