Imaging in Endoscopic Cranial Skull Base and Pituitary Surgery.

Endoscopic endonasal approaches have widely accepted techniques for managing benign and malignant processes along the entire ventral skull base with similar or better results compared with open procedures, but with lower rates of complication. Managing pathology affecting the skull base can be challenging because of complex anatomy and the proximity of critical neurovascular structures. Postoperative imaging can be challenging, because of surgical alterations of normal anatomy and the now common use of complex reconstruction techniques. Understanding the normal imaging appearance of skull base reconstruction is important for accurate postoperative interpretation and delineation between normal reconstructive tissue and recurrent neoplasm.

Endovascular approach of tibial peroneal trunk pseudo-aneurysm / Reparación endovascular de pseudo-aneurisma del tronco tibioperoneo

This is a case report of a patient with tibioperoneal trunk pseudoaneurysm secondary to firearm injury. Through endovascular intervention, two covered stents were placed on the lesion, with exclusion of the pseudoaneurysm and preservation of the vessel of origin. Arterial Doppler follow up 20 days after intervention revealed adequate stent permeability. In cases of complex extremity trauma with osteo-musculo-vascular involvement, endoluminal repair seems to be a useful tool in distal vessels.

Se informa el caso de un paciente con pseudo-aneurisma del tronco tibioperoneo secundario a herida por arma de fuego. Mediante un método endovascular se colocaron dos stents cubiertos en el sitio de la lesión, con exclusión del pseudo-aneurisma y preservación del vaso de origen. En el control con doppler arterial a los 20 días de la intervención se evidenció adecuada permeabilidad del stent. En casos complejos de trauma de los miembros, con compromiso ósteo-músculo-vascular, la reparación endovascular parece ser una herramienta útil en los vasos distales.
