Introduction:
While hypertension, pericardial, myocardial, and coronary artery disease are common cardiovascular manifestations of systemic lupus erythematosus (SLE), aortic aneurysms (AA) are rare but increasingly diagnosed, with the true incidence unknown.
Case report:
A 40 year old female suffering from SLE with a 5.3 cm saccular eccentric infrarenal abdominal aortic aneurysm (AAA) was treated successfully with endovascular aneurysm repair (EVAR) using the Medtronic Endurant II bifurcated stent graft and followed up 2 years post-operatively. Pre-operatively, open and EVAR options were offered and the latter was chosen by the patient.
Discussion:
Proposed mechanisms for AA formation in SLE including accelerated atherosclerosis brought about by chronic steroid use and SLE associated vasculitis and cystic medial degeneration (CMD) have been discussed in other case reports and series. To the authors' knowledge, the use of EVAR for AAA in SLE patients has not been reported in available literature. The need for earlier repair, screening, and detection as well as the long-term suitability, durability, and surveillance of EVAR remain unknown. The benefit of using the Ovation device in minimising late neck dilatation is also discussed.
Conclusion:
EVAR was demonstrated to be a suitable form of repair in a young female patient with SLE and AAA, followed up 2 years post-surgery. The ideal repair and the natural history of these aneurysms remains to be studied.
