Abstract(s)
A cirurgia intracraniana não é ainda uma prática corrente em Medicina Veterinária, apresentando limitações associadas à variabilidade morfológica craniana dos doentes, à dificuldade da técnica de intervenção cirúrgica inerente às estruturas envolvidas, ao acesso a sofisticados meios de diagnóstico e constituição de equipas especializadas. Um sólido conhecimento sobre as relações anatomotopográficas cranioencefálicas que apresentem repetibilidade, permite ao neurocirurgião desenhar mentalmente as afinidades existentes entre as estruturas superficiais e as mais profundas, assumindo ainda as que se interpõem ao longo da trajectória cirúrgica traçada, melhorando a orientação topográfica pré e intra-cirurgica em cada doente, diminuindo em muito os riscos da cirurgia e aumentando a probabilidade de êxito. O presente trabalho desenvolvido em 69 crânios e respectivos 138 hemisférios cerebrais (direito e esquerdo) considerando canídeos do tipo braquicéfalos, dolicocéfalos e mesacéfalos, permitiu concluir que o que os parece diferenciar mais é o esqueleto facial de cada um, mais do que a caixa craniana, já que as relações anatomotopográficas cranioencefálicas estudadas apresentaram uma repetibilidade evidente para os pontos craniométricos, suturas cranianas e estruturas/pontos encefálicos seleccionados, quanto à sua localização (distância e posição) em todos eles.
ABSTRACT - ANATOMOTOPOGRAPHY CRANIOENCEPHALIC RELATIONSHIPS FOR INTRACRANIAL NEUROSURGERY PROCEDURES IN DOG. THE ULTRASOUND AS TECHNIQUE OF NEURONAVEGATION FOR SURGERY IN REAL TIME. - Despite intracranial surgery is still not a current practice in Veterinary Medicine, showing some limitations associated with cranial morphological variability of patients, the difficulty of interventional technique is inherent to work area and the access to sophisticated diagnostic methods. A solid knowledge about anatomotopography cranioencephalic relationships showing some repeatability, allows the neurosurgeon mentally draw the similarities between the surface and deeper structures, even assuming those that stands along the surgical pathway, improving the pre and intra-orientation topography in each patient, reducing the risks of surgery and increasing probability of success. The present work developed over 69 cranium and respectively 138 brain hemispheres (right and left) considering the brachy, dolico, and mesacephalic cranium dogs, concluded that which seems to further differentiate the 3 types of skull is the face of each one more than cranium, since all the anatomotopographic cranioencephalic relationships showed some evident repeatability for craniometric points, cranial sutures and encephalic structures/points considered, regarding their localization (distance and position)
