Thromboembolic phenomena involving the caval veins, right atrium, and pulmonary artery are recognised complications after the Fontan operation and other forms of total cavopulmonary connection. A rare case of systemic thromboembolism is reported in a 3 year old girl who had repeated coronary and cerebral thromboembolic events after a fenestrated total cavopulmonary shunt operation. A survey of the 18 paediatric cardiac units in the United Kingdom and Ireland showed a wide discrepancy in anticoagulation policies after Fontan-type operations. Prevention of thrombotic complications by lifelong postoperative anticoagulation may outweigh the risk of haemorrhage.
A 14-month-old boy presented with hepatoblastoma, which was completely excised. He had pulmonary metastases, diagnosed 1 year later, treated with chemotherapy followed by resection at age 2 1/2 years. At the age of 3 1/2 years a further metastasis was shown on CT scan and this was resected. Two further metastses were resected at ages 4 1/2 and 5 1/2 years. At age 9 1/2 he had a further isolated pulmonary metastasis resected and is again disease-free more than 30 months from the last thoracotomy. Prolonged survival following metastatic hepatoblastoma can be achieved with repeated thoracotomies, especially if the first recurrence is more than 6 months from diagnosis and the number of metastases is small. Follow-up examinations should be both radiological and with serum alpha fetaprotein (S alpha FP).
SUMMARY
The tenth case of primary tumour arising in the stump of ureter following nephrectomy has been reported, and the features of these cases, both benign and malignant, reviewed. A brief historical review of the pathology of the stump of the ureter precedes a definition of this tumour. When compared to malignant tumours arising in the intact ureter, the clinical and diagnostic features are similar, but a high incidence of squamous cell carcinoma and of multiple tumours is reported in these cases of tumour arising in the stump of ureter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
