“…In their study consisting of 897 cases, Sheehan et al detected that GOS was the factor that showed a significant correlation (29). In our study, 76.2% of the patients were GOS grade 1 and grade 2, and this result was statistically significant (p<0.05) (Table VIII) ( Figure 6).…”

“…It was shown that acute hydrocephalus and intraventricular hemorrhage, severe clinical course, hypertension, alcoholism, gender, large aneurysm size and infections such as pneumonia and meningitis were important factors in the development of chronic hydrocephalus (12,13,22,29). In our study, an increase was observed in the incidence of hydrocephalus in patients with meningitis and it was statistically significant (p<0.05) (Table IX) ( Figure 7).…”

and 67% (29). It was found that communicating hydrocephalus is a well-defined and known complication (36). The patients with hydrocephalus following SAH have a worse prognosis than others without hydrocephalus.The aim of our study is to detect the etiology of postoperative hydrocephalus in patients with aneurysm that follows SAH and to determine the primary factors that influence the development of hydrocephalus. Determining these factors is of great importance in terms of treatment strategies, patient mortality and morbidity. The identification of patients, who have the potential for developing hydrocephalus and giving extra-attention to this patient group, is also important. █ INTRODUCTION G enerally, arterial hemorrhage and rarely, venous hemorrhage into the subarachnoid space are called "subarachnoid hemorrhage" (SAH). Although 50-75% of the SAHs are caused by aneurysms, the reason for 13-25% of the cases are unknown (11,18).Hydrocephalus following SAH due to aneurysm rupture can cause worsening of neurological course with the increase in intracranial pressure. The increase in intracranial pressure due to hydrocephalus is lowered with external ventriculostomy or ventricular shunt. Previous studies determined that the rate of hydrocephalus development following SAH was between 6% AIm: Factors affecting the development of postoperative hydrocephalus patients who underwent surgery after aneurysmal subarachnoid hemorrhage were retrospectively assessed. mATERIAl and mEThODS: 201 cases, who underwent aneurysm surgery in our clinic after subarachnoid hemorrhage between 2008 and 2013, were retrospectively assessed. Twenty-one cases with hydrocephalus development were retrospectively examined according to their age, gender, history (hypertension, alcohol, and smoking), blood type, the number and size of aneurysms, aneurysm localization, the presence of ventricular hemorrhage, baseline-final neurological diagnosis, Fisher grading system, history of vasospasm and meningitis. The initial neurological course and Hunt-Hess, and also final neurological course of the patients were evaluated according to World Federation of Neurosurgical Societies (WFNS) Grading Scale. RESUlTS:Age, history of hypertension, aneurysm localization, Hunt-Hess grading, vasospasm, meningitis and Glasgow Outcome Scale (GOS) are determinative factors in hydrocephalus development due to subarachnoid hemorrhage. It was detected that gender, alcohol and tobacco use, blood group, the size and the number of aneurysm, the presence of intraventricular hemorrhage and Fisher grading were not the determinative factors in the patients. CONClUSION:In patients who underwent surgery for subarachnoid hemorrhage, risk factors for postoperative hydrocephalus should be determined and the patients with these risk factors should be closely monitored.

“…En la fase aguda de la HSA, la dilatación del sistema ventricular como consecuencia de la formación de coágulos en las cisternas basales y el taponamiento de las vellosidades aracnoideas, por fi brina proveniente de la sangre extravasada provoca aumento de la presión intracraneal (PIC) 27 . En este contexto, los resultados del estudio con DTC ofrece información indirecta sobre el estado de PIC a través de los cambios que se registren en el índice de pulsatilidad (IP) de las arterias cerebrales media 28 .…”

This review summarizes the usefulness of transcranial Doppler (TCD) ARTÍCULO DE REVISIÓN IntoducciónL a idea de estudiar la circulación intracraneal con ultrasonido fue inicialmente propuesta en 1960 por Kaneko en Osaka 1 . Hasta ese momento el cráneo se consideraba una barrera infranqueable para el ultrasonido y sólo había sido estudiado el estado de la circulación cerebral con métodos invasivos. En 1965 Miyazaki y Kato utilizaron por primera vez caudalímetros direccionales ultrasónicos basados en el empleo del efecto Doppler para el estudio de las arterias carótidas, y desde ese momento comienza a utilizarse el ultrasonido de forma rutinaria para el estudio de los vasos extracraneales, mientras los vasos intracraneales sólo habían sido abordados en el curso de intervenciones quirúrgicas o en niños con fontanelas abiertas ya que el hueso de los adultos atenuaba excesivamente las ondas de los aparatos diagnósticos, que operaban a frecuencias de 5 a 10 MHz 2 .En 1982, Rune Aslid se percata de que el problema de penetrar el ultrasonido dentro del cráneo podía resolverse utilizando una menor frecuencia de ultrasonido y aprovechando áreas del cráneo donde el hueso fuera más fi no. De esta forma, utilizando una probeta de 2 MHz y un equipo designado originalmente para uso cardíaco introduce en la práctica clínica el Doppler transcraneal (DTC) 3 . Dos años después de haber descrito en sujetos normales las características del fl ujo sanguíneo en los segmentos proximales de los vasos que conforman el polígono de Willis, comenzó a aplicarlo en el diagnóstico y seguimiento del vasoespasmo en la HSA 4 .En poco tiempo, impulsado por su naturaleza no invasiva y la ventaja de poder realizarse junto al enfermo, el DTC comienza a ser introducido en la evaluación de otras afecciones cerebrovasculares 5 .Hasta el año 1994, las investigaciones se concentraron en el vasoespasmo de la circulación anterior REV CHIL NEURO-PSIQUIAT 2011; 49 (1): 79-85
