Extracranial internal carotid artery aneuriysms (EICAA) are rare. There are few reports in the medical literature about its etiology, relating these aneurysms to atherosclerosis, arteritis and alterations due to trauma or after surgical procedure. The natural history of the disease has not been well-defined yet. However, the potential risk of embolism originating from the aneurysm -or even its rupture -indicates a need for intervention. We present the case of a seventy-one year old woman, who was diagnosed an aneurysm of three cm diameter of the right EICA, with throbbing headache complaints. After an unsuccessful attempt of endovascular treatment, we performed a surgical procedure with aneurysmectomy and primary end-to-end anastomosis near the skull base.Keywords: aneurysm; internal carotid artery; surgery. ResumoOs aneurismas de artéria carótida interna (ACI) extracraniana são raros. Há poucos relatos na literatura médica quanto à sua etiologia, relacionando-os à doença aterosclerótica, às arterites e alterações decorrentes do trauma ou após procedimento cirúrgico. A história natural da doença ainda não está bem estabelecida. Entretanto, o potencial risco de embolia originário do aneurisma ou mesmo de sua ruptura indica necessidade de intervenção. Apresentamos o relato de caso de uma mulher de 71 anos diagnosticada com aneurisma de 3 cm de diâmetro da ACI extracraniana direita com queixas de cefaleia pulsátil. Após tentativa sem sucesso de tratamento endovascular, optou-se pelo tratamento cirúrgico com aneurismectomia e anastomose primária término-terminal próximo à base do crânio.Palavras-chave: aneurisma; artéria carótida interna; cirurgia.

The usefulness of ileocolic sphincter (ICS) transplantation to the neck after a total laryngopharyngectomy was investigated in 12 mongrel dogs. The authors aimed to evaluate the influence of the transplantation on ICS pressure amplitude and ICS length, and on ICS resistance to intracecal pressure increase. Electromanometric measurements showed that ICS pressure amplitude and length presented no changes after the procedure. Also, there was no significant change in ICS resistance. However, long-term follow-up studies are needed to determine whether the ileocolic transition maintains the properties observed in the immediate postoperative period.
