Abstract

AIM: The correlation between hematoma volume and outcome in ruptured arteriovenous malformations (AVM) with accompanying posterior fossa hematoma was retrospectively evaluated. MATERIAL and METHODS: Microsurgery operations were performed on 127 patients with intracranial AVM between January 1998 and January 2009 at our clinic. Fifteen (11.8%) patients were identified as suffering from posterior fossa AVM, and twelve of these patients presented with a cerebellar hematoma. All patients were clinically evaluated according to the following criteria: modified Rankin Scale (mRS) prior to surgery, Spetzler-Martin grade (SMG) of the AVMs, hematoma volume prior to surgery, and mRS following surgery. RESULTS: Postoperative mRS scores were significantly lower than preoperative scores (p=0.0001). Postoperative outcomes were concordant with the SMG of the AVMs (r=0.67, p=0.033), hematoma volume (r=0.537, p=0.072) and preoperative mRS scores (r=0.764, p=0.004). These analyses show that the postoperative mRS score is strongly correlated with a preoperative mRS score, hematoma volume and SMG. CONCLUSION: Posterior fossa AVMs present an increased risk for hemorrhage and for increased morbidity and mortality. Cases with hematoma should be operated on an urgent basis. We conclude that hematoma volume is a factor that impacts postoperative results and prognosis. SMG and preoperative mRS scores were also correlated with outcome.

Özet

AMAÇ: Rüptüre posterior fossa arteriovenöz malformasyonlarda hematom volümü ile klinik sonuç arasındaki İlişki retrospektif olarak değerlendirildi. YÖNTEM ve GEREÇ: 1998 ile 2009 arasında kliniğimizde 127 hasta intrakranyal arteriovenöz malformasyon nedeniyle mikrocerrahi ile ameliyat edildi. Bu hastaların 15 tanesi (%11,8) posterior fossa AVM’si idi. Bu Serebellar AVM li hastaların da 12’si serebellar hematoma ile başvurdu. Serebellar hematomlu AVM hastalarının; ameliyat öncesi modifiye Rankin Skalası (mRS), Spetzler-Martin grade (SMG) ve hematom volümü, ameliyat sonrası modifiye Rankin Skalası ile karşılaştırmalı olarak değerlendirildi. BULGULAR: Postoperatif mRS skoru istatistiksel olarak anlamlı şekilde preoperatif skordan daha düşük bulundu (p=0,0001). Postoperatif klinik sonuç; AVM’nin SMG’I (r=0,67, p=0,033), hematom volümü (r=0,537, p=0,072) ve preoperatif mRS (r=0,764, p=0,004) ile uyumlu bulundu. Nörolojik defisit AVM’nin SMG’i ile uyumlu şekilde artmış idi. İncelemeler göstermektedir ki, postoperatif mRS, preoperatif mRS, hematom volümü ve SMG ile daha fazla ilişkilidir. SONUÇ: Posterior fossa AVM ler, kanama riski ile beraber artan morbidite ve mortalite riski taşıyan kompleks nörovasküler lezyonlardır. Hematomlu vakalar acil şekilde opere edilmelidir. Hematom volümü klinik sonuç ile ilişkidir. Biz hematom hacminin, postoperatif klinik sonuç ve prognoz üzerinde etkili bir faktör olduğu sonucuna vardık. Ayrıca preoperatif SMG ve mRS de klinik sonuç üzerinde etkilidir.
