Migration of atrial catheter of ventriculo-cysto-atrial shunt into heart and pulmonary artery - case report and literature review.

Ventriculoatrial shunts are the alternative treatments when it is impossible to use ventriculoperitoneal shunts. Limited indication for ventriculoatrial shunt is due to the possibility of very serious complications inherent with this procedure. We present a case report of a young patient who suffered from disconnection of an atrial catheter from the valve after an accidental blow to his neck. The atrial catheter was dislocated to the heart and pulmonary artery and it was extracted through the femoral vein in the groin area using an endovascular technique. The procedure went without complications. A new atrial catheter was introduced under ultrasonic guidance during surgical revision.

Epidural Hematoma, a Rare Complication After the Use of Mayfield Clamp: A Case Report and Review of the Literature.

Herein, we describe a case of epidural hematoma associated with the use of a Mayfield head clamp. An 18-year old patient with an upper brainstem tumour causing obstructive hydrocephalus underwent a routine third ventriculostomy, which unexpectedly revealed an intracranial hemorrhage. We outline potential risk factors, propose an algorithm for preventing complications associated with the use of pin-type fixation, and conducted a structured review of the literature to identify similar clinical scenarios.
