Ultrasound (US)-guided peripheral venipuncture was performed for peripheral insertion of 222 central venous catheters over a 12-month period. Initial placement was successful in 218 patients but unsuccessful in eight; placement was successful in four the next day (success rate, 98%; complication rate, 5%). Catheters were in place from 3 days to 6 months (mean, 36 days). US guidance allowed successful venipuncture for placement of central venous catheters in children.

In small children, MDCT is a feasible and promising method for assessing stent associated complications in the treatment of CHD. Cardiac surgeons and interventional cardiologists might rely on this imaging modality to plan specific interventions more precisely and to assess the results upon follow up.

Meckel's diverticulum is the most common congenital anomaly of the small intestine, occurring in about 2 % of the population. The most common complications associated with a Meckel's diverticulum include obstruction, bleeding, and inflammation (7, 9, 11, 18-20). The estimated lifetime risk of developing symptoms with a Meckel's diverticulum is 4-6 % (16), with the risks of complications decreasing with age. Stones within Meckel's diverticulum are recognized as a rare complication in the adult population (13,15). However, it has not been reported in the pediatric age group. The authors describe a 19-month-old male who presented with intermittent abdominal pain and vomiting, chronic microcytic anemia and a calcified stone in the lower abdomen, who was found to have a Meckel's enterolith.
