BACKGROUND: Preoperative delineation of any vascular anomalies offers planning for possible alteration of surgical procedures, especially in pediatric recipients undergoing living-related liver transplantation. PURPOSE: We assess the efficacy of three-dimensional (3D) multislice computed tomography (CT) angiography in the hope of replacing conventional angiography as the pretransplant evaluation of the hepatic vascular system for potential recipients of liver transplantation. METHODS: 3D CT angiography was performed in 38 children with biliary atresia. Conventional angiography was also performed in the first 15 patients. Twelve patients underwent living-related liver transplantation. The findings on 3D CT angiography were compared with conventional angiography and operative findings. RESULTS: 3D CT angiography was successfully performed in 37 pediatric patients. All findings of 3D CT angiography on hepatic artery, portal vein, and inferior vena cava paralleled those of catheter angiography and operative findings. Four patients were unsuitable to receive living grafts because of pathologic insults of the hepatic artery (one patient) and the portal vein (three patients). Three patients were advised to undergo a venous graft for portal anastomoses. Eight patients demonstrated portosystemic shunts that may require closure. CONCLUSION: 3D CT angiography proves to be a better tool in the demonstration of the vascular system and identification of pathologic insults in pediatric patients. It is superior to conventional angiography because it is less invasive, more convenient, and more efficient in providing thorough preoperative information that would have a major impact on patient selection and surgical planning.
Endovascular treatment of ruptured vertebrobasilar artery aneurysms with Gugliemi detachable coils (GDC) has become an alternative to surgery. Mid-term angiographic follow-up can now be reported. Of 111 vertebrobasilar aneurysms in 110 patients we treated with GDC since 1992, 53 underwent angiography within 1 year and 59 after more than 18 months. We did not achieve complete occlusion on initial treatment of 23 aneurysms (21%). Complications were observed in 19 patients (17%), leading to permanent clinical disability in eight. Enlargement of the neck or reopening was seen in 12 (23%) of 53 aneurysms followed by angiography within 12 months. Documented recanalisation was treated in four (8%). Angiography was performed after 18-78 months in 59 patients, of whom nine, including three with initially incomplete occlusions, were retreated with GDC. Within the entire second observation period, three (5%) of the 59 patients had a further haemorrhage and were retreated with GDC. Rebleeding proved to be the only factor influencing the clinical outcome of retreated patients.
INTRODUCTION: Desmoplastic infantile gangliogliomas (DIG) are rare cerebral glioneural tumors usually occurring in early childhood. DIGs are generally benign although rare cases with poor outcome are known. Total resection, if possible, is the treatment of choice, without further adjuvant therapy. After incomplete resection, adjuvant chemo-and/or radiotherapy is generally applied, despite the potential negative side effects in such young patients. CASE REPORTS: We describe two girls with DIG, one who twice underwent subtotal resection at 3 and 5 months, the other who underwent total resection at 2 years. Neither had adjuvant therapy and there was no tumor recurrence. CONCLUSIONS: Our own experience and a review of the literature suggest that in most DIGs adjuvant therapy is not justified even after incomplete resection. After tumor recurrence a second surgical intervention should be considered instead of adjuvant therapy. An exception may be made for rare, deep-seated DIGs, which are more aggressive and have a poorer outcome.
