ABSTRACT To report a wide-necked renal artery aneurysm treated successfully with stent-assisted Gugliemi detachable coil occlusion, assisted by three-dimensional (3-D) angiography.
A 56-year-old woman with history of hypertension presented with a 2.5-cm wide-necked saccular aneurysm involving her distal right renal artery. A balloon-expandable stent was positioned across the neck of the aneurysm and multiple Gugliemi detachable coils were deployed through a microcatheter inserted through the interstices of the stent into the aneurysm sac, guided by 3-D angiography. Follow-up 3-D angiography at 6 months revealed a patent renal artery with continued exclusion of the aneurysm and preservation of renal blood flow.
Stent-assisted coil occlusion assisted by 3-D angiography is a potential renal-sparing endovascular approach to treating wide-necked renal artery aneurysms with complex vascular anatomy.

    ABSTRACT: Renal artery aneurysm is a rare disorder with a high mortality rate in the event of rupture, the most frequent complication, which can also occur in lesions smaller than those indicated for treatment by current criteria. Surgery is still the first-line treatment, although a growing trend toward endovascular management of visceral artery aneurysms has emerged because of the high efficacy and low invasiveness that has been demonstrated by several authors. Treatment of wide-necked aneurysms and, depending on location, those at renal artery bifurcations or distal branches is more complex and may require invasive surgical techniques, such as bench surgery.

    ABSTRACT: Therapeutic embolization in renal pathology is used for various conditions in cancerology, traumatology, urology, nephrology and for iatrogenic complications of percutaneous manoeuvers. Any department of vascular radiology may be requested to use this technique, especially in emergent traumatology or palliative cancerology. The authors study the various conditions that may benefit from these procedures and give the highlights of the main indications and the main types of embolic agents used. Complications, side effects and the major precautions are also reviewed.

    ABSTRACT: Peripheral arterial aneurysms are uncommon; for some aneurysm types, data are limited to case reports and small case series. There is no Level A evidence in most cases to determine the choice between open or endovascular intervention. The evolution of endovascular technology has vastly improved the armamentarium available to the vascular surgeon and interventionalists in the management of these rare and unusual aneurysms. The choice of operative approach will ultimately be determined on an individual basis, dependent on the patient risk factors, and aneurysm anatomy. After consideration, some aneurysms (femoral, subclavian, carotid and ECAA) fare better with an open first approach; renal, splenic and some visceral artery aneurysms do better with an endovascular first approach. In our practice PAAs are treated with an endovascular first approach. For these rare conditions, both open and endovascular therapy will continue to work in harmony to enhance and extend the capabilities of modern surgical management.
