A case report of stent-assisted renal artery aneurysm coil embolization

Huang Jinqi

Abstract：We successfully treated a 62-year-old female patient with a right renal aneurysm using stent-assisted coil embolization,achieving significant therapeutic effects.The patient was admitted to the hospital due to the discovery of the right renal aneurysm,and her left kidney had already atrophied and lost function,increasing the difficulty and risk of the surgery.To ensure safety,the surgery was conducted in two stages:the first stage involved right renal artery angiography to assess the aneurysm's location and anatomical relationships;the second stage involved interventional embolization.Preoperative discussions confirmed that the aneurysm was located near the renal hilum,with the feeding artery supplying the upper pole of the kidney,necessitating embolization while maintaining renal artery blood flow.Therefore,we chose stent-assisted coil embolization.Key points of the surgery included strictly adhering to indications,selecting the appropriate timing and method,and preserving distal renal arteries and branches as much as possible.This endovascular treatment method offers the advantages of being minimally invasive,safe,effective,and associated with fewer complications.
