RESUMO
Ingested sharp-pointed foreign bodies can cause serious complications. A case of a 16-year-old girl with cardiac tamponade due to ingestion of a sewing needle is presented. Ingested needles have often been reported as a cause of gastrointestinal injuries but in this rare case the sewing needle actually migrated into the myocardium.

OBJECTIVE: To determine the effect of increasing inferior vena cava blood flow by means of distal arteriovenous fistula on the patency of a peritoneal tube graft. MATERIALS AND METHODS: In 16 mongrel dogs, a 3-4 cm long circular defect was created at the infrarenal inferior vena cava. The defect was interposed with peritoneal tube graft. A temporary distal femoro-femoral arteriovenous fistula was also constructed in 8 dogs just after the caval interposition. Graft patency was evaluated by Doppler ultrasonography and angiography. Histological evaluation was also performed. RESULTS: Seven dogs in each group survived. All control grafts occluded within the first week, compared to no occlusions in fistula group (Fisher's exact test, p<0.005). However one 'fistula' dog with a still patent graft was sacrificed on the 18th day due to ultrasonographically occluded arteriovenous fistula. CONCLUSION: In dogs, the peritoneum may be used as graft material for reconstruction of the inferior vena cava, provided a distal arteriovenous fistula is constructed.
