“…Etiyolojiye bakıldığında serimizde en sık kardiyoemboli (%47,3) gözlenmiş olup gruplar arasında (grup 1-%45,7, grup 2-%50) anlamlı istatistiksel farklılık gözlenmedi. Önceki çalışmalar ile karşılaştırıldığında kardiyoemboli sıklığı Arboix (%21,6), Lee (%20) ve Kumral'a (%17) göre daha sık, Ntaios'a (%52,9) göre daha az ve Yamamota (%41) ile benzer oranda idi (7)(8)(9)(18)(19)(20). Ayrıca KaE grubunda Ntaios'a benzer şekilde kortikal PSA enfarkt üstünlüğünü saptadık (20).…”

“…Ayrıca KaE grubunda Ntaios'a benzer şekilde kortikal PSA enfarkt üstünlüğünü saptadık (20). Daha önce yapılmış çalışmalarda EPSAH sıklığı %1,7 ile %16 aralığında değişen oranlarda gözlenirken çalışmalara konvansiyonel MR veya MRA dahil edilmesi ile bu oranın (%18,5, %30, %43,6, %49,6, %50,6) arttığı görülmektedir (7)(8)(9)12,19,21). Serimizde ikinci sıklıkta gözlediğimiz EPSAH (%21,1) grubunda 12 hastanın 7'sinde kortikal PSA, 5'inde PSA+ enfarktı mevcuttu.…”

“…Proksimal arteryel hastalığı (%17,5) grubunda sıklıkla lezyon İKVA'de saptandı. Son geniş serilerde etyoloji saptanamayan hastaların oranı %8-32 arasında bildirilmiştir (9,11,12,14,18,19,(21)(22)(23)(24)(25). Bizim serimizde bu oran %14,1 idi.…”

Bulgular: Otuz beş hasta (%61) PSA kortikal dal enfaktüsü geçirirken, 22 hastada (%39) kortikal ve derin PSA besleme alanında enfarkt saptandı. Etyolojiye bakıldığında her iki grupta da kardioembolizmin (n=27, %47) daha sık olduğu saptandı. Bunu sırayla entrensek PSA hastalığı (n=12, %21), proksimal arter hastalığı (n=10, %17), kriptojenik emboli (n=8, %15) izledi. İnme başlangıcında hastaların %52 baş ağrısı gösterdi. Hastaların %78'inde görme alanı bozuklukları, %54'ünde motor semptomlar, %24'ünde duysal semptomlar mevcuttu.Sonuç: PSA kortikal ve derin sulama alanındaki enfarktlarda kardiyojenik emboli ve entrensek PSA hastalığının daha sık olduğu düşünüldü. PSA kortikal dal enfarktı olanlar ile derin ve kortikal dal enfarktı olanlar arasında etyoloji ve risk faktörleri açısından anlamlı istatistiksel değişiklik saptanmadı.

Materials and Methods:Fifty seven patients who suffered strokes first time and have infarcts in the PCA perfusion area and admitted to our Neurology Clinics between January 2002 and August 2007 were included in this study. Subjects were divided in two groups as cortical branch infarct group and deep (thalamus) + cortical branch group. Patients were evaluated in four etiologic clusters; 1. Occlusion in the posterior cerebral artery or its branches. 2. Occlusion proximal to the posterior cerebral artery. 3. Cardio-embolic reasons. 4. Cryptogenic embolism group. All patients had cranial CT, MRI, neck Doppler USG, MRA or DSA, transesophageal or trans-thoracic echocardiography, hematologic and vasculytic investigations. Risk factors in all patients were recorded.

“…In the New England Medical Center Posterior Circulation registry, cardiac-origin embolism was less frequent than anterior circulation embolism (24 vs. 38% of patients) [20,21]. Ntaios et al [22], reporting on 185 patients with posterior cerebral artery (PCA) infarction, showed that atrial fibrillation was less prevalent in patients with posterior circulation infarcts without PCA territory involvement (17.3 vs. 39.5%). Arboix [23 ]states that a cardiac source of embolus is a less frequent mechanism in PCA infarctions than in those of the middle and anterior cerebral arteries.…”

Background: Our clinical experience suggests that the outcome of cerebellum-brainstem ischemic strokes is better than that of hemispheric ischemic strokes. Methods: Within the setting of 2 national Israeli prospective stroke surveys, we analyzed risk factors, etiology, severity at presentation, and prognosis of first ischemic cerebellum-brainstem stroke (259 patients), comparing with strokes within the anterior circulation (1,029 patients). Results: Patients with cerebellum-brainstem strokes were younger and had less frequently atrial fibrillation and congestive heart failure. Cardioembolic etiology was significantly less prevalent (p < 0.001). Severity at presentation was milder (p < 0.001). At discharge, worsening of the modified Rankin Scale was present in a smaller number of patients (p < 0.001); more returned to their home (p < 0.001). Six-month and 1-year mortality were lower (p < 0.001 for both). Adjusted logistic regression models showed that patients with cerebellum-brainstem strokes had 50% smaller chances of dying (OR 0.55; 95% CI 0.31–0.98) and a smaller chance of worsening of the modified Rankin Scale at discharge (OR 0.61; 95% CI 0.46–0.82). Conclusions: Cerebellum-brainstem strokes are less frequently cardioembolic, have a less severe presentation, and carry a better immediate and long-term prognosis.

“…Probably, the most active field was that of stroke pathophysiology, treatment and outcomes . The role of genetics in pre‐disposition towards stroke attracts much attention, and there are several complex genetic traits with differences between ethnic groups.…”
