Portal vein thrombosis after splenectomy for hereditary stomatocytosis in childhood.

UNLABELLED: Portal vein thrombosis is a rare but potentially lethal complication in children requiring splenectomy. We report on a 15-year-old boy with a dehydrated hereditary stomatocytosis, who underwent splenectomy and presented a postoperative partial portal vein thrombosis. With prompt heparin therapy, neither propagation of the thrombus nor further cavernous transformation in the following occurred 6 years.

CONCLUSION

Recent data suggest that hereditary stomatocytosis carries a high risk of thrombotic complications, especially after splenectomy. This procedure, the benefit of which is limited in this condition, should therefore be strongly avoided.
