A 62-year-old man developed recurrent TIAs presenting as mild unconsciousness, dysarthria and weakness of the right upper extremity lasting for 15 to 20 minutes. He was found to have severe iron deficiency anemia (hemoglobin: 5.5-5.9g/dl; hematocrit: 18.4-19.5%) which insidiously developed through the chronic bleeding from the gastric ulcer. He had slight hypertension (184/86mmHg), but no orthostatic hypotension. DSA and MR angiography showed severe stenosis at the origin of the bilateral internal carotid arteries and of the left vertebral artery. There was also hypoplasia of the right vertebral artery. Blood circulation detected by 123I-IMP-SPECT was markedly decreased in the whole brain and in the right hemisphere of the cerebellum. TIA was, however, completely disappeared following to the recovery of anemia. The present case suggested that the presence of severe anemia accelerated the occurrence of hemodynamic TIA (regional cerebral anemic hypoxia), which is probably the consequence of the reduced oxygen-transporting capacity of the blood.

Although radio-frequency (RF) ablation has been accepted as a promising and safe technique for treatment of unresectable hepatic tumors, investigation of its complications has been limited. According to the multicenter (1,139 patients in 11 institutions) survey data of the Korean Study Group of Radiofrequency Ablation, a spectrum of complications occurred after RF ablation of hepatic tumors. The prevalence of major complications was 2.43%. The most common complications were hepatic abscess (0.66%), peritoneal hemorrhage (0.46%), biloma (0.20%), ground pad burn (0.20%), pneumothorax (0.20%), and vasovagal reflex (0.13%). Other complications were biliary stricture, diaphragmatic injury, gastric ulcer, hemothorax, hepatic failure, hepatic infarction, renal infarction, sepsis, and transient ischemic attack. One procedure-related death (0.09%) occurred (due to peritoneal hemorrhage). Three important strategies for decreasing the rate of complications are prevention, early detection, and proper management. A physician who performs RF ablation of hepatic malignancies should be aware of the broad spectrum of major complications so that these strategies can be used.
