Endonasal clipping of unruptured right paraclinoid aneurysm. Case report in a third level center in Mexico City.

Paraclinoid aneurysms take importance due to the technical difficulty due to anatomical relationships, which is why different approaches have been sought for their proper management. This is a female patient with a finding of a paraclinoid aneurysm and treatment using an endonasal approach with adequate angiographic support. Knowledge of the anatomy and surgical skill are required for the management of these lesions, assisted by angiographic controls for successful treatment. The endoscopic endonasal approach is adequate if the anatomy allows it and the basic hospital infrastructure is available to obtain high success rates.

Los aneurismas paraclinoideos cobran importancia debido a la dificultad técnica por sus relaciones anatómicas, por lo que se han buscado diferentes abordajes para su adecuado manejo. Se presenta el caso de una paciente con un aneurisma paraclinoideo y tratamiento mediante abordaje endonasal con apoyo angiográfico adecuado. Se requieren conocimientos de la anatomía y habilidad quirúrgica para el manejo de estas lesiones, así como asistencia de controles angiográficos para el éxito del tratamiento. El abordaje endonasal endoscópico es adecuado en caso de que la anatomía lo permita y se tenga la infraestructura hospitalaria básica para obtener un alto índice de éxitos.

Intracranial hypertension syndrome secondary to internal jugular vein thrombosis due to miliary cervical tuberculosis: A case report.

BACKGROUND: Thrombosis of the internal jugular vein (IJV) is extremely rare, being central catheterization the most common cause. We present a case of a patient with an unusual appearance of neurological symptoms as a consequence of thrombosis of the IJV secondary to miliary tuberculosis. CASE DESCRIPTION: A 30-year-old woman with disseminated tuberculosis, with multiple lymphadenopathy, axillary, cervical, mesenteric, retroperitoneal, and inguinal, presented with clinical evidence of intracranial hypertension. A diagnostic cerebral angiography was performed, which revealed an occluded left internal jugular and venous stasis in the entire cerebral venous system. The patient was treated with low-molecular-weight heparin, with which she had an adequate evolution. CONCLUSION: Tuberculosis is capable of generating a state of hypercoagulability, in addition to a mechanical compression effect due to cervical lymphadenopathy. We report an unusual clinical presentation, with intracranial involvement due to IJV thrombosis secondary to miliary tuberculosis. So far, there are no cases with a similar presentation described above.
