One-stage hybrid repair of multiple degenerative aneurysms.

The development of multiple aneurysms in different segments of the arterial tree requiring treatment is a challenge for the vascular surgeon as their management often demands more than one surgical procedure. We report a case of a 71-year-old male suffering from multiple aneurysms in four different segments of the arterial tree in combination with disabling claudication of his left leg. The patient was managed in a single session with a combination of classic open surgical and endovascular techniques in order to treat his aneurysms and revascularize his leg. This case illustrates the prospect to combine classic open surgical and endovascular techniques for the optimal management of multileveled arterial pathology. Combined therapy simplifies management and allows the one-stage treatment of these patients, while minimizing the overall operative risk.

Postoperative levels of cardiac troponin versus CK-MB and high-sensitivity C-reactive protein for the prediction of 1-year cardiovascular outcome in patients undergoing vascular surgery.

OBJECTIVE: This study evaluated comparatively the predictive value of postoperative cardiac troponin I (cTnI), creatinine kinase (CK)-MB, and high-sensitivity C-reactive protein (hs-CRP) in 1-year cardiovascular mortality and morbidity in patients undergoing elective vascular surgery. METHODS: A total of 295 consecutive patients undergoing elective noncardiac vascular surgery were prospectively followed-up over a period of 12 months. The levels of cTnI, CK-MB, and hs-CRP were measured preoperatively and 24 h after operation. The primary endpoint was the composite of cardiovascular death, nonfatal acute myocardial infarction, ischemic stroke, and unstable angina. RESULTS: The primary endpoints occurred in 11 patients (3.8%). Receiver operating characteristic curve analysis showed that postoperative cTnI was a strong predictor of a cardiovascular event during 1-year follow-up (area under the curve, 0.852; P<0.001). Areas under the curve for hs-CRP and for CK-MB were 0.734 (P=0.008) and 0.494 (P=0.947). A threshold cTnI value of 0.4 ng/ml was highly associated with the occurrence of a cardiovascular event, with a sensitivity of 80% and specificity of 81%. Furthermore, cTnI levels provided a significantly better prediction than CK-MB levels (P=0.009) and tended to be superior to hs-CRP (P=0.2). CONCLUSION: Postoperative cTnI levels seem to be superior to CK-MB and hs-CRP levels for the prediction of 1-year cardiovascular mortality and morbidity in patients undergoing elective vascular surgery.
