Surgical removal of an ectopic haemodialysis catheter in the brachiocephalic artery: a case report.

Percutaneous central vein catheterization is commonly performed to access venous circulation for various clinical indications. However, unintentional arterial puncture may occur which can result in catastrophic complications. We report a case of an inadvertent right brachiocephalic artery cannulation in a 77-year-old lady planned for haemodialysis via a percutaneous internal jugular vein vascular access performed under ultrasound guidance. As an intravascular stent is not favourable in view of the close proximity of the right common carotid artery to the site of puncture as well as the risk of massive bleeding upon simple removal of the catheter, an open surgical removal via a median sternotomy was performed. Acquiring the competency in procedural skills, an understanding of the surgical anatomy and anticipating impending complications are of paramount importance in preventing as well as in mitigating the above complication.

Operative challenges in a gigantic ganglioneuroma of the posterior mediastinum with mediastinal compression.

Symptomatic giant ganglioneuromas with mediastinal compression are rare, complicating its management with significant morbidity and mortality risks. A meticulous multidisciplinary preoperative planning is pivotal in ensuring success. We describe a case of a 30-year-old man with a giant posterior mediastinal mass with compression and displacement of the mediastinal structures. Biopsy confirmed a ganglioneuroma and patient underwent excision. Surgery was challenging in view of the size and adherence to the local structures. Haemodynamic instabilities were encountered necessitating a pre-emptive femoral-femoral cannulation for CPB. A piece-meal debulking of the tumour was performed, complicated with massive haemorrhage requiring autologous blood transfusion using an intraoperative blood salvage device. The patient recovered and was discharged home well at Day 8. A thorough pre-operative planning involving a multidisciplinary approach, an understanding of the surgical anatomy as well as anticipating impending complications is of paramount importance  in the management of this particular case.
