Purpose
Aneurysms and pseudo-aneurysms of the renal arteries are a rare condition.
The incidence of the aneurysms is 0,1-1% in the general population increasing to 2,5% in the hypertensive population.
Clinically they are usually asymptomatic and are found incidentally in diagnostic imaging studies for other reasons.
The most common symptoms are abdominal or back pain,
hematuria and poorly controlled hypertension.
Aneurysmal rupture is considered a life threatening condition,
and treatment is accepted in the following circumstances:
- Asymptomatic renal aneurysm: if the diameter exceeds 15 mm or if enlargement is observed in successive imaging studies.
- Symptomatic renal aneurysm.
- Pregnant females or future desire pregnancy (80% rate of rupture during pregnancy time).
On the other hand,
renal pseudo-aneurysms are vascular lesions that arise when an arterial injury within the kidney leads to contained hemorrhage.
They appear in relationship with traumatism,
renal surgery,
renal puncture as well as inflammatory,
infectious and neoplastic processes.
Pseudo-aneurysms usually close spontaneously,
but when they remain open can be harmful and require treatment.
Treatment options for renal aneurysms and pseudo-aneurysms are open surgery or percutaneous endovascular procedures. Our goal is to review the different techniques and devices used in the endovascular treatment of a group of patients with aneurysms and pseudo-aneurysms of the renal arteries.
