[INTRODUCTION - The congenital absence of celiac trunk and it’s subtotal stenosis are rare abnormalities and often recognised only during digital substraction angiography (DSA). This anomaly is significant when there is a need to perform local intraarterial chemoperfusion or chemoembolisation of malignant hepatic tumours. In these cases the liver is supplied with arterial blood through the superior mesenteric artery and the gastroduodenal arch. The direction of blood flow in the common hepatic artery is changed ensuring the flow to the splenic and left gastric artery. In such circumstances it is not possible to obtain local chemotherapy. CASE REPORT - Two male patients (61 and 75 years old) are reported. Both patients were candidates for chemotherapy due to hepatocellular carcinoma (HCC). In these two cases the planned therapy was impossible because of a stenosis of the celiac trunk in one, and atresia of the celiac trunk in the other. CONCLUSION - The recognition of vascular anomaly prior to endovascular intervention significantly affects the planning of the therapy.]

[INTRODUCTION - Complications after subtotal esophageal extirpation (for eg.: insufficiency of anastomosis, stricture, etc.) and their treatment have special radiological considerations. Surgical departments and their radiologists meet early complications. But, all other radiological departments can face late complications, so the knowledge of these is important for all radiologists. PATIENT AND METHODS - 58 subtotal esophageal extirpations were performed in the last 5 years in the 1st Department of Surgery, Semmelweis University, Budapest. All postoperative radiological examinations were undertaken by the Department of Diagnostic Radiology and Oncotherapy. Most plain chest X-rays and swallowing examinations were made per-os with non ionic water soluble, low osmolarity contrast media on the 7th postoperative day. Further examinations were performed only if needed clinically. RESULTS - The complications were categorized as early and late. Early complications were aspiration, anastomosis insufficiency (31% of cases). Nine cases had self-dilating stents placed because of suture insufficiency. Further complications were noted following stenting (eg.: occlusion, dislocation of stent, closure of stent because of granulation tissues). Amongst late complications, stomach dilatation caused by pylorus-spasm (1 case), stricture of anastomosis (14 cases) and ’too-long’ esophageal stump (3 cases) were seen. CONCLUSION - Conventional radiology has a major role in diagnostics and treatment of complications of esophageal extirpation. Dynamic radiological examination and team work are required between the radiologist and surgeon. Also, it is crucial to cultivate good cooperation in cases of stent implantation, as contrary to the published literature, we find it better to have stents placed under flouroscopy rather than endoscopically.]

[Since the introduction of electrolytically detachable coils the endovascular treatment of intracranial aneurysms is dynamically developing. The good results with this technique led to a progressive expansion of the indications. For the treatment of complex, wide-necked and fusiform aneurysms several new devices and techniques were developed. The introduction of a new device is possible after a feasibility study. In these studies the number of cases is low. Some risk factors or possible complications occur only after the introduction of a new device to the market.]
