Embolization of a renal artery branch pseudoaneurysm
Endovascular embolization of a renal artery branch pseudoaneurysm is performed under local anesthesia and sedation. Following Seldinger puncture of the common femoral artery, an introducer sheath is placed. Diagnostic renal angiography is performed to localize the pseudoaneurysm and assess the vascular anatomy. Selective catheterization of the affected branch is achieved using a microcatheter. An embolic material is delivered into the pseudoaneurysm lumen or into the feeding vessel. Depending on the anatomical features and operator preference, microcoils (Guglielmi detachable coils or fibered coils), liquid embolic agents (Onyx, glutaraldehyde-acrylic copolymer), or a combination thereof are used. Completion angiography is performed to confirm complete occlusion of the pseudoaneurysm and preservation of blood flow in the unaffected renal artery branches. After removal of the introducer sheath, compression of the puncture site is applied for hemostasis.
