Recurrent perforations of viscus due to ventriculoperitoneal shunt in a hydrocephalic child.

In this report, we describe the first case of recurrent perforations of viscus due to ventriculoperitoneal shunt for the treatment of hydrocephalus. Based on our own experience and a survey of literature, we suggest that perforation of the gastrointestinal tract should be suspected in patients with ventriculoperitoneal shunt, particularly when abdominal symptoms or ventriculitis are presented. To manage this complication, at the first perforation in the present case, a fibrin sealant was effective for closure of the perforated stomach wall. At the second perforation, when laparotomy was performed, we could not find any abnormality in the abdominal cavity except for a sheath and slight omental adhesions near it.

Chylothorax following bochdalek herniorrhaphy in an infant

A case of chylothorax following Bochdalek herniorrhaphy in an infant is presented. To our knowledge, it is only the third case to be reported in the literature.

Newborn with congenital arteriovenous fistulas of the abdominal wall complicated by a ductus arteriosus aneurysm

A case of congestive heart failure in a neonate resulting from a congenital abdominal arteriovenous fistula is described; an aneurysm of the ductus arteriosus was also found in the patient. Abdominal aortography was performed and demonstrated dilated feeding arteries, including the hypogastric arteries, which communicated with a dilated umbilical vein. Ligation of the feeding arteries and the umbilical vein led to resolution of the heart failure. Transient liver dysfunction occurred, however. Symptoms improved dramatically upon removal of the ligature from the umbilical vein. Although there is one previous report of an arteriovenous fistula involving the umbilical vein, we know of no prior report of a congenital arteriovenous fistula in association with a ductus arteriosus aneurysm.

New operative method for tracheal compression in congenital heart disease

A new technique is described for repairing tracheal compression caused by ascending aorta associated with corrected transposition of the great arteries and pulmonary atresia in a 113-day-old infant. Surgical repair for the tracheal compression was accomplished by suspending the pericardium around the aortic arch to the underside of the sternum. This method seems to be useful for some patients with tracheal compression caused by the ascending aorta.
