Coronary artery bypass grafting (CABG) has evolved to become an incredibly safe and effective therapy for ischaemic heart disease. Despite advances in revascularization both with and without cardiopulmonary bypass, cerebrovascular events continue to occur following CABG. Many of these events have been directly related to aortic manipulation (cannulation, aortic clamping, proximal anastomotic devices), and this fact has led a number of surgeons to consider and implement a surgical revascularization strategy whereby the aorta is not manipulated at all. This ‘no-touch’ technique utilizes a number of conduits and orientations in order to achieve complete myocardial revascularization while eliminating aortic manipulation and significantly decreasing the risk of perioperative stroke. Outcomes of patients who suffer a permanent stroke after CABG are dismal. In-hospital mortality rates for patients suffering a permanent stroke after CABG have been reported to be as high as 13.5%. Following discharge from the hospital, patients who suffered a perioperative stroke have a significantly higher risk of mortality within the first year following surgery.

The review presents the current concept oftotal arterial myocardial revascularization, main studies focusing on it, recent guidelines and commonly used techniques, which let speak about high efficacy this kind procedure. However, in medical society there is a certain part of disbelief with respect to performance of coronary artery bypass grafting using only arterial conduits, and even in justifiable cases when the choice is obvious, the percentage of mentioned operations is still low. It can be explained by both technically much more difficult manipulations and particular risk factors, which contribute discreet approach in the wide use of total arterial myocardial revascularization.

Aim. To assess the long-term outcomes of coronary artery bypass grafting (CABG) and their association with calcification biomarkers.Material and methods. The study included 129 men (mean age, 61,5±7,5 years) with coronary atherosclerosis who were admitted for CABG surgery. Patients were divided into 2 groups: with favorable and unfavorable (death, myocardial infarction, stroke, surgery) 5-year prognosis after surgery. Before the surgery, the blood concentrations of calcification biomarkers (osteoprotegerin, osteopontin, osteonectin and osteocalcin) were determined in all patients.Results. Long-term outcomes of myocardial revascularization were studied in 92 patients (71%). An unfavorable long-term 5-year period was identified in 28 men (30,4%). In men with an unfavorable 5-year prognosis, the blood osteocalcin level before CABG was 1,2 times higher than in men with a favorable one. Multivariate linear regression showed that the risk of a 5-year unfavorable prognosis for coronary atherosclerosis after myocardial revascularization was associated with the blood osteocalcin concentration, determined before CABG (B=0,018, R2=0,285, p=0,008).Conclusion. The data obtained indicate the relevance of continuing studies on osteocalcin, including with respect to its contribution to coronary atherosclerosis and calcification.

Auksė Meškauskienė, Egidijus Vytautas BarkauskasVilniaus universiteto Neurologijos ir neurochirurgijos klinikos Neuroangiochirurgijos centrasŠiltnamių g. 29, LT-04130 VilniusEl paštas: [email protected] Įvadas / tikslas Viena iš dažniausių nechirurginių mirties priežasčių po miego arterijos endarterektomijos yra operacinis miokardo infarktas. Miokardo revaskulizacija pagerina širdies darbą, užkerta kelią miokardo infarktui, todėl praeityje atliktos aortovainikinių jungčių operacijos ar vainikinių arterijų angioplastika turėtų sumažinti kardiologines komplikacijas ligoniams, kuriems operuojama susiaurėjusi miego arterija. Darbo tikslas – išsiaiškinti, ar praeityje atlikta vainikinių arterijų angioplastika ar aortos ir vainikinių arterijų jungčių operacijos sumažina miego arterijos endarterektomijos komplikacijų skaičių ir operacinio miokardo infarkto riziką. Ligoniai ir metodai Vilniaus greitosios pagalbos universitetinės ligoninės Neuroangiochirurgijos centre per 1995–2003 metus atliktos 569 vidinės miego arterijos endarterektomijos. Per šį laikotarpį operuoti 45 ligoniai, kuriems praeityje sėkmingai atlikta vainikinių arterijų angioplastika arba aortovainikinės jungtys. Išanalizuoti šių ligonių rizikos veiksniai, operacijos indikacijos ir komplikacijos. Rezultatai Iš 569 operuotų ligoniai mirė 16 ligonių, o 10 ligonių ištiko insultas. Bendras komplikacijų skaičius buvo 4,6%. Po operacijos miokardo infarktu susirgo 7 ligoniai (1,2%), vienas iš jų mirė. Ligoniai, kuriems praeityje buvo sėkmingai atlikta vainikinių arterijų angioplastika ar aortos ir vainikinių arterijų jungtys, po miego arterijos endarterektomijos miokardo infarktu nesusirgo. Šios grupės du ligonius ištiko operacinis insultas, vienas iš jų mirė. Bendras komplikacijų skaičius buvo 3,8%. Išvados Praeityje suformuotos aortovainikinės jungtys ar atliktas vainikinių arterijų plėtimas vidinės miego arterijos stenoze sergantiems ligoniams padėjo išvengti operacinio miokardo infarkto ir nepadidino bendro komplikacijų skaičiaus. Prasminiai žodžiai: miego arterijos endarterektomija, aortovainikinės jungtys, vainikinių arterijų angioplastika, komplikacijos Results of carotid endarterectomy after previous coronary-artery bypass grafting or angioplasty Auksė Meškauskienė, Egidijus Vytautas Barkauskas Background / objective The patients that died of medical complications after carotid endarterectomy all died from cardiac causes. Intraoperative myocardial infarction is one of the common medical complications of carotid endarterectomy. The previous myocardial revascularization can reduce cardiac mortality in patients undergoing carotid endarterectomy. We evaluated whether there is a protective effect of previous coronary artery bypass grafting or percutaneous transluminal angioplasty in patients undergoing carotid endarterectomy. The aim of the study was to review the results of carotid endarterectomy in patients with previous coronary artery bypass grafting or coronary angioplasty with respect to perioperative myocardial infarction. Patients and methods From January 1995 through December 2003, 569 carotid endarterctomies were performed (447 male, 122 female; mean age 64 years) at the Neurovascular Surgery Centre of Vilnius University Emergency Hospital. We extracted from all the operative group patients with previous successful coronary artery bypass grafting or coronary artery angioplasty (n=45) and reviewed them for clinical factors, indications for operation and complication rate. All patients were assessed for the presence of perioperative myocardial infarction, total morbidity and mortality. Results During 9 years, 569 patients underwent carotid endarterctomy. There were 16 perioperative complications: 16 deaths and 10 postoperative strokes. Perioperative myocardial infarction occurred in 7 patients, one was fatal. The total rate of complications was 4.6%. In the 45 patients with previous coronary artery bypass grafting or coronary angioplasty no postoperative myocardial infarction was noted. Two patients suffered postoperative strokes, one of them died. The operative complication rate (stroke and death) in this series was 3.8%. Conclusions The previous myocardial revascularization did not change the overall mortality and postoperative stroke rate, but reduced cardiac mortality and morbidity in patients undergoing carotid endarterectomy. Keywords: carotid endarterectomy, coronary artery bypass grafting, coronary artery percutaneous transluminal angioplasty, operative risk, complications
