[Pseudoaneurysm in the radial artery after catheterization]. / Seudoaneurisma de arteria radial post-canulación.

Eleven days after surgery to remove an olfactory groove meningioma, a woman developed a pulsatile swelling and localized elevation of temperature in the radial artery catheterized to monitor arterial pressure. Pseudoaneurysm of the radial artery was diagnosed and the patient was returned to the operating room for ligation and biopsy of the vessel under regional anesthesia. Her condition worsened in spite of the resection and 48 hours after repair of the arterial pseudoaneurysm she was admitted to the intensive care unit with septic shock. Radial artery catheterization is a safe, frequently performed procedure but it is not free of risk. The most common complication is thrombosis. Much more rare are pseudoaneurysms, lesions that are observed late after catheterization (7-40 days) and are associated with vessel wall alterations, repeated puncture attempts, and catheter infection. The usual therapeutic approach involves surgical resection and ligature of the vessel, although other measures have been suggested.

Seudoaneurisma de arteria radial post-canulación / Pseudoaneurysm in the radial artery after catheterization

Una paciente intervenida de un meningioma del surcoolfatorio desarrolló once días después de la cirugía unatumoración pulsátil acompañada de fiebre en la zona dela arteria radial canulada para monitorizar la presiónarterial invasiva. Con el diagnóstico de seudoaneurismade la arteria radial fue conducida de nuevo a quirófanodonde se realizó ligadura y biopsia de dicho vaso bajoanestesia regional. A pesar de la resección sufrió un deterioroprogresivo de su situación clínica, precisando ingresoen la unidad de cuidados intensivos (UCI) 48 horasdespués de la reparación de la formación seudoaneurismáticaarterial con el diagnóstico de shock séptico.La canulación de la arteria radial es un procedimientohabitual y seguro, aunque no exento de complicaciones.La más frecuente es la trombosis, siendo mucho másrara la formación de seudoaneurismas, lesión que seobserva tardíamente (7-40 días) tras su cateterización yse asocia a alteración en la pared de los vasos, repetidosintentos de punción o infección del catéter. Aunque sehan propuesto otras opciones terapéuticas la más extendidaes la resección quirúrgica y ligadura del vaso

[Postoperative cortical blindness after resection of a retroperitoneal teratoma]. / Ceguera cortical postoperatoria tras resección de teratocarcinoma retroperitoneal.

We present a rare case of cerebrovascular accident involving non-cardiac, non-neurological, non-carotid surgery in a 44-year-old man with no cardiovascular risk factors who underwent retroperitoneal resection of a teratocarcinoma, immediately after which he showed signs of confusion accompanied by cortical blindness. Neurological signs and symptoms remitted completely 5 days after surgery. Complementary tests and the patient's evolution confirmed a diagnosis of reversible ischemic neurological deficit.
