Renal artery aneurysm: An endovascular treatment for a rare cause of hypertension

The diagnosis and endovascular therapy of renal artery aneurysm: A 32-patient case report

RATIONALE

Renal aneurysm is a rare disease with the atypical symptoms and mostly diagnosed by imaging modalities. Endovascular therapy is a one of treatment methods.

PATIENT CONCERNS

A retrospective analysis of 32 patients with renal artery aneurysm, from June 2010 to May 2016 in our hospital, was made in our study. All of them underwent therapy, and the effects and perioperative characteristics of it were analyzed.

DIAGNOSIS

32 patients were taken contrast-enhanced CT and diuretic renal dynamic imaging to evaluate the state of illness.

INTERVENTIONS

The preoperative blood creatinine, perioperative hemoglobin and relief of hypertension were performed.

OUTCOMES

The preoperative blood creatinine was slightly increasing, while the perioperative hemoglobin was slightly decreasing. The relieving hypertension was performed in 9 of patients.

LESSONS

Endovascular therapy is a mature and feasible treatment method. There is little effect on hemoglobin and renal function in postoperation, while it can also decrease the blood pressure.

Renal artery aneurysms: movement toward endovascular repair

Renal artery aneurysm (RAA) is an uncommon disease and is typically an incidental finding on imaging performed for other medical ailments. Sequelae of RAA include rupture and difficult to control hypertension. Repair of RAA is considered in suitable surgical candidates when a maximum diameter of 2 cm is reached or in those females who are pregnant or trying to conceive. Surgical options have expanded from traditional open aneurysmectomy or arteriorrhaphy to robotic-laparoscopic repair and a manifold of endovascular approaches.
