<p>Ciljevi: Cilj ove studije je da ispita bezbednost rane karotidne endarterektomije (CEA) u odnosu na odložene CEA nakon akutnog ishemijskog neurološkog deficita (TIA/CVI). Drugi cilj je da istražimo da li postoji razlika u brzini neurološkog oporavka između navedenih grupa. Metode: Ukupno 157 ispitanika u prospektivnoj studiji je praćeno 30 dana postoperativno. Grupa I ili rana CEA, je imala 50 ispitanika operisanih od 3. do 14. dana po TIA/CVI događaju. Grupa II ili odložena CEA, je imala 107 ispitanika operisanih od 15. do 180. dana nakon TIA/CVI. Praćen je proceduralni opšti i specifični morbiditet i mortalitet u 30-dnevnom postoperativnom periodu. Rankin skor (mRS) smo koristili za procenu neurološkog invaliditeta. U odnosu na vrednost mRS skora smo formirali dve podgrupe mRS<3 i mRS3. U statističkoj analizi koristili smo Pirsonov hi test, Studentov test, ANOVU analizu varijanse, Boniferonijev test i multiplu analizu varijanse za ponovljena merenja (GLM- general line model), kao i parametarsku i neparametarsku korelaciju i regresiju. Nivo značajnosti je bio 0,05. Rezultati: Prosečna starost ispitanika je bila 66,72 godine uz 66,2% osoba muškog pola. U grupi I je prosečno vreme do intervencije bilo 9,5 dana, a u grupi II 72,22 dana. Grupe su homogene u odnosu na faktore rizika i komorbiditet. Grupa I je imala 54% nestabilnih aterosklerotskih plakova u poređenju sa grupom II gde ih je bilo 31,8% (χ2 = 7.084; p < 0.01). U grupi I TIA je imalo 50% ispitanika, a u grupi II CVI nalaza je bilo 68,2% (χ2 =4.825; p <0.05). CVI do 1 cm veličine je statistički značajno više zastupljen u grupi I , a CVI do 2 cm u grupi II (χ2 = 6.913; p <0.05). Stopa CVI je u grupi I bila 2.0% a u grupi II je 2.8% (F = 0.083; p > 0.05). Stopa postoperativnog infarkta miokarda (IM) je u grupi I je 2.0% a u grupi II je 1.9%. Stopa specifičnog hirurškog morbiditeta je u grupi I 4.0% a u grupi II 3.7%. U grupi I ukupni morbiditet bio 6.0% a u grupi II 7.5%, razlika nije bila statistički značajna (F =0.921; p > 0.05). Mortaliteta u obe grupe nije bilo. CVI/IM/smrt stopa je u grupi I bio 4.0% a u grupi II je bio 4.7% (F = 0.122; p >0.05). Hiperlipidemija je signifikantan faktor rizika za CVI/IM/smrt (χ2 = 4.083; p < 0.05). Poboljšanje mRS je u grupi I imalo 52%, a u grupi II 31,8% pacijenata (χ2 = 5.903; p <0.01). Relativni rizik je 2,4 odnosno toliko puta je veća šansa da kod bolesnika dođe do promene mRS ako je bolesnik u grupi I. Pad mRS koji nastupa između trećeg i desetog dana nakon CEA je statistički visoko značajno izraženiji u grupi ranih CEA ( F 3,701 df 1 p=0,029). Kod bolesnika sa TIA u preko 60% slučajeva došlo je do pada mRS, a kod onih koji su imali CVI u oko 25.5% (χ2 = 18.050; p < 0.01). Kod Rankin skora podgrupe mRS<3 i mRS3 je pad bio značajan i po vremenu (F 18,774; df 6; p=0,000) i po podgrupi ali je daleko brži pad zapažen u podgrupi mRS<3(F 6,010; df 1; p=0,003). Zaključak: Rana CEA je jednako bezbedna kao i odložena CEA u pogledu incidence perioperativnog morbiditeta i mortaliteta. Ranom CEA se postiže znatno brži neurološki oporavak pacijenata, naročito onih sa TIA i mRS<3 skorom.</p> / <p>Objectives: The aim of this study was to investigate the safety of early carotid endarterectomy (CEA) in relation to the delayed CEA after acute ischemic neurological events (TIA / CVI). The second objective was to investigate whether there is a difference in speed of neurological recovery between these groups. Methods: A total of 157 patients in the prospective study followed 30 days postoperatively. Group I or early CEA, had 50 patients operated from 3 to 14 days after TIA / CVI event. Group II or delayed CEA, had 107 patients operated from 15 to 180 days after the TIA / CVI. Accompanied by the general and specific procedural morbidity and mortality in 30-day postoperative folow up. Rankin score (mRS) were used for evaluation of neurologic disability. In relation to the value of mRS score we formed two subgroups mRS <3 i mRS3. In the statistical analysis we used the Pearson chi test, Student's test, ANOVA analysis of variance, Boniferony test and multiple analysis of variance for repeated measures (GLM- general line model), as well parametric and nonparametric correlation and regression. The significance level was 0.05. Results: The mean age was 66.72 years with 66.2% of males. In Group I is the average time to intervention was 9.5 days, and in group II 72.22 days. The groups were homogeneous in relation to risk factors and comorbidities. Group I had 54% of unstable atherosclerotic plaques compared with group II, where it was 31.8% (χ2 = 7.084; p <0.01). In the group I TIA had 50% of respondents, while in group II CVI was 68.2% (χ2 = 4.825; p <0.05). CVI to 1 cm in size were significantly more frequent in the group I, a CVI to 2 cm in group II (χ2 = 6.913; p <0.05). CVI rate in the group I was 2.0%, and in group II was 2.8% (F = 0.083, p> 0.05). Postoperative myocardial infarction (MI) in the group I is 2.0%, and in group II was 1.9%. Specific surgical morbidity rate in the group I and 4.0% in the group II 3.7%. In group I total morbidity was 6.0% in group II 7.5%, the difference was not statistically significant (F = 0.921; p> 0.05). Mortality in both groups was not. CVI/IM/death rate in group I was 4.0% in group II was 4.7% (F = 0.122; p> 0.05). Hyperlipidemia is a significant risk factor for CVI/IM/death (χ2 = 4.083; p<0.05). Improving mRS in the group I had 52% and in group II 31.8% of patients (χ2 = 5.903; p <0.01). The relative risk was 2.4 times as much and is more likely to occur in patients mRS changes if the patient in group I. Improving mRS that occurs between the third and tenth days after CEA was highly statistically significantly greater in the group of early CEA (F 3,701 df 1 p = 0.029). In patients with TIA in 60% of cases there was a decline mRS, and those had CVI in about 25.5% (χ2 = 18.050; p <0.01). In Rankin score subgroups mRS <3 i mRS 3 the decline was significant and time (F 18,774; df 6; p =0.000) and in the subgroup but it is far more rapid decline observed in the subgroup mRS <3 (F 6.010; df 1; p = 0.003). Conclusions: Early CEA is as safe as the delayed CEA in respect incidence of perioperative morbidity and mortality. Early CEA is achieved significantly faster recovery of neurological patients, especially those with TIA and mRS <3 compared with delayed CEA.</p>
