I read the excellent study of Pacini and colleagues [1] with great interest. They stated that surgery for inflammatory aortopathy is associated with high morbidity and mortality (23.1% vs 10% in their experience) when compared with inflammatory and noninflammatory patients. They pointed out that a systemic inflammatory process that affects all vessels is a major reason for higher morbidity and mortality.
Inflammation is one of the pathologic hallmarks of Behçet's disease, which affects vessels of all sizes, known as "vasculo-Behçet" [2]. One of the major manifestations of vasculo-Behçet is arterial aneurysm formation, which occured in only 1 patient in Pacini and colleagues' [1] series. Pacini and coworkers [1] performed antegrade selective cerebral perfusion and aortic repair. The upper right brachial artery [3] and left subclavian artery [4] are used for cannulation in patients for aortic arch repair in our clinic. The cannulation vessel is important, because cannulation would be a serious problem for the choice of patients with multi-vessel inflammatory diseases.
Omitting surgery may avoid acute exacerbation of inflammatory aortopathy and avoid formation of new aneurysms at the site of the suture line. The authors should explain why new aneurysm formation was fewer than expected, because immunosupresive therapy was not used. Was other antiinflammatory therapy used during follow-up? If so, why was the mortality higher than their overall rate for thoracic aortic repair?
Pacini and coworkers [1] recommend that preoperative measurement of C-reactive protein and erythrocyte sedimentation rate for all patients undergoing aortic surgery. Erythrocyte sedimentation rate and C-reactive protein may not add information because Zouboulis and coworkers [5] found high serum levels of interleukin-8 in patients with active Behçet's disease with vascular involvement. Endotelial cells could be responsible for secretion of interleukin-8 during the active phase; thus monitoring erythrocyte sedimentation rate and C-reactive protein might not be reliable without interleukin-8, especially in patients with Behçet's disease.
