Abstract

Introduction: Hemorrhagic transformation (HT) after acute ischemic stroke (AIS) can be seen at any time following ischemic stroke. Although HT usually occurs as a complication of antithrombotic, anticoagulant, or thrombolytic treatments, it can also occur spontaneously. We aimed to investigate the occurrence of early HT and its relevant risk factors in patients diagnosed with acute middle cerebral artery (MCA) infarction who were not treated with thrombolytic agents.Methods: We recruited 171 patients with acute MCA infarction between January 2011 and July 2012 who were not treated with thrombolytic agents and were suitable to our inclusion criteria. Controlled neuroimaging was performed immediately in patients with deterioration, otherwise on day 7 following stroke. All patients were investigated for AIS risk factors and biochemical analyses were performed. Patients with HT in controlled neuroimaging were grouped both clinically (i.e., symptomatic or asymptomatic) and radiologically, according to "European Cooperative Acute Stroke Radiological Study" (ECASS), and risk factors were examined Results: We enrolled 171 patients [94 men (55%) and 77 women (45%)] in the study. HT developed in 37 patients (21.63%). In terms of risk factor analysis, the most frequent etiological factor was atherosclerosis in AIS patients (50.3%). National Institutes of Health Stroke Scale scores were significantly higher both in sHT patients according to asHT patients and in HT patients on day 7 compared with their initial scores. Serum low-density lipoprotein (LDL-C), triglycerides (TG), and total cholesterol (TC) levels were significantly lower in patients with HT (p<.001).Conclusion: HT is a major complication in AIS that considerably increases the morbidity and mortality. To reduce the occurrence of HT, risk factors for each patient population should be determined. Acute thrombolytic therapy should be used cautiously in high-risk patients, and appropriate alternative therapies should be revised in them.

Özet

Amaç: Akut iskemik inme (Aİİ) sonrası hemorajik dönüşüm (HD) iske-mik atağı izleyen herhangi bir dönemde olabilir. HD günümüzde yaygın olarak kullanılan antitrombotik, antikoagülan ya da trombolitik tedavilerin komplikasyonu olarak görülürse de spontan olarak da oluşabilir. Bu çalışma ile orta serebral arter (OSA) sulama alanında akut infarkt tanısı konulan ve trombolitik tedavi uygulanmamış hastalarda erken evrede HD görülme oranı ve ilişkili risk faktörlerinin incelemesi amaçlanmıştır.Yöntem: Çalışmaya Ocak 2011-Temmuz 2012 tarihleri arasında Aİİ ile başvuran, trombolitik tedavi uygulanmamış ve çalışma kriterlerine uygun 171 OSA infarktı tanılı hasta alınmıştır. Klinik izlemde nörolojik bulgular-da kötüleşme olanlara hemen, diğerlerine yedinci günde kontrol nörogö-rüntüleme yapılmıştır. Akut iskemik inme risk faktörleri araştırılmış, rutin biyokimyasal analizleri yapılmıştır. Kontrol nöro-görüntülemerinde HD saptananlar hem klinik durumlarına göre (semptomatik veya asempto-matik), hem de radyolojik olarak "European Cooperative Acute Stroke Study" (ECASS) kriterlerine göre gruplara ayrılarak risk faktörleri ince-lenmiştir.Bulgular: Çalışmaya 171 hasta [94'ü (%55) erkek ve 77'i (%45) kadın] alınmıştır. HD 37 (%21,63) hastada gelişmiştir. Risk faktörü sıralamasında Aİİ tanısı alan hastalarda en sık ateroskleroz (%50,3) saptanmıştır. NIHSS skoru hem semptomatik HD hastalarında asemptomatik olanlara göre, hem de HD hastalarının 7. günlerinde başlangıç değerlerine kıyasla anlam-lı olarak yüksek saptanmıştır. Serum düşük dansiteli lipoprotein (LDL-K), trigliserit (TG), total kolesterol (TK) seviyeleri HD hastalarda anlamlı ola-rak düşük saptanmıştır.Sonuç: HD akut iskemik inmenin morbidite ve mortalitesini arttıran majör bir komplikasyonudur. HD görülme riskinin azaltılabilmesi için, toplumlar için ayrı ayrı risk faktörleri saptanmalıdır. Riskin yüksek olduğu hastalarda trombolitik tedavi uygulanırken dikkatli olunması ve HD riskini azaltacak alternatif tedavilerin gözden geçirilmesi uygun olacaktır.
