Ultrasound Guided Laparoscopic Port Placement in a Patient with Congenital Anomaly of IVC Undergoing Sleeve Gastrectomy

We report a patient with obesity who underwent laparoscopic sleeve gastrectomy after pre-operative ultrasound mark up to enable safe port insertion due to presence of venous collaterals in the abdominal wall as a result of congenial IVC anomaly. This patient was falsely presumed to have NASH cirrhosis. Detailed preoperative workup ruled this out and led to the discovery of congenital IVC anomaly as the cause of engorged blood vessels in the anterior abdominal wall. On table ultrasound mark up of safe sites for port insertion enabled a safe laparosocpic sleeve gastrectomy on this patient.
