- Abstract
A 41-year-old man was admitted for symptoms of progressive congestive heart failure. His family history and the results of a physical examination were highly suggestive of Osler-Weber-Rendu disease (hereditary hemorrhagic telangiectasia, HHT). Cardiac catheterization and hepatic angiography demonstrated HHT with left-to-right shunting from the liver. The patient underwent transcatheter arterial embolization (TAE) of the right hepatic artery. We performed both Doppler sonography and angiography before and after TAE. The treatment improved the clinical manifestations of congestive heart failure, including the edema of the leg and dyspnea. Doppler sonographic studies also showed an increased resistive index in the right hepatic artery and decreased flow volumes and velocities in the right and middle hepatic veins, respectively, after treatment. Corresponding changes on angiography after TAE showed decreased right hepatic arterial flow and nonopacified branches distal to the coils, disappearance of the mottled hepatogram in the right lobe, reduction of contrast agent staining, and enhanced calibers in the right and middle hepatic veins. This case illustrates that qualitative and quantitative studies with duplex and color Doppler ultrasound can be used to detect or define the extent of hepatic involvement in HHT patients before TAE, monitor hemodynamic changes of the intrahepatic vasculature after TAE, evaluate the efficacy of treatment, and possibly obviate the need for repeated angiography for diagnosis only.

- Abstract
Sepsis and liver abscess are serious complications following transarterial embolization (TAE) for hepatocellular carcinoma (HCC). However, the exact incidence and the necessity of antibiotic prophylaxis remain undetermined. Between November 1996 and November 1997, we prospectively studied bacterial infections in 231 HCC patients who underwent 287 angiographic procedures without antibiotic prophylaxis, including 176 TAEs and 111 hepatic arteriographies (HAs). Four of the 111 HAs were complicated by transient asymptomatic bacteremia. Of the 176 TAEs, 2 were associated with asymptomatic bacteremia, and 7 (4%) were associated with symptomatic bacterial infection, including 3 cases of sepsis, 2 of liver abscess, and 2 of infected biloma. For patients with HCC, TAE was associated with a higher risk of developing symptomatic bacterial infections than was HA (4% vs. 0, respectively; P = .03). Previous gastrectomy was the only possible risk factor for liver abscess. Finally, early diagnosis and treatment of these infectious complications usually result in successful outcome.

- Abstract
Transcatheter arterial embolization (TAE), a common treatment for patients with unresectable hepatocellular carcinoma (HCC), can provoke severe physical discomfort and psychologic stress. The purpose of this study was to investigate the effect of a combination of health education, muscle relaxation, and back massage on reducing physical and psychologic stress in HCC patients receiving TAE. A quasi-experimental design was used. Forty patients with HCC (30 men and 10 women) with a mean age of 57 +/- 12 years were recruited and randomly assigned to the control or experimental group. The effectiveness of the stress management program was evaluated using a knowledge questionnaire, a worry inventory, a state-trait anxiety inventory, and a physical distress scale. After completing the stress management program, the experimental group had a greater mean increase in knowledge score than the control group (5.1 vs 0.8, p < 0.0001) and a greater mean decrease in worry score (-8.2 vs 1.1, p < 0.0001). The mean decrease in the anxiety score in the experimental group was also significantly greater than in the control group before TAE (-5.8 vs 3.2, p < 0.001) and 2, 4, 6, and 7 days after TAE (-8.2 vs 7.1, p < 0.001; -8.7 vs 3.2, p < 0.001; -9.8 vs -2.1, p < 0.05; -11 vs -0.9, p < 0.05). The patients in the experimental group had a smaller mean increase in physical distress score than the control group at 2, 4, 6, and 7 days after TAE (34.7 vs 50.2, 20.9 vs 29.6, 10.6 vs 18.2, 3.9 vs 11.2, all p < 0.05). This stress management program effectively reduces the stress of HCC patients undergoing TAE.

- Abstract
This report describes a female baby having a hemangioma over the right thigh that had appeared as an irregular bruise since two days old. Severe thrombocytopenia, consumptive coagulopathy, anemia, and heart failure developed at three months old. With a diagnosis of Kasabach-Merritt syndrome, systemic corticosteroid, vincristine, subcutaneous alpha-interferon, and massive plate transfusion were given. However, the platelet count remained low and the skin lesion enlarged gradually. Trans-feeding-arterial embolotherapy with a 5 ml pure ethanol (1 ml/kg) injection was performed at four months of age. Thirty days later, her platelet count recovered and the hemangioma shrunk in size. This case illustrates that absolute ethanol embolotherapy is an effective treatment for hemangioma with Kasabach-Merritt syndrome and may be life-saving for those with lesions refractory to medical therapy.

- Abstract
Objectives: To present the clinical and microbiological features of liver abscess after transarterial embolization (TAE) for hepatocellular carcinoma (HCC)., Methods: We retrospectively reviewed records of 452 TAE procedures in 289 patients with HCC over a 2-yr period., Results: Four men and one woman with a mean age of 68.4 yr were diagnosed with liver abscess 1-8 wk (mean 4.6 wk) after the embolization. The incidence was 1.1% (5/452). Common symptoms included fever, chills, and right upper quadrant pain. Serum aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase levels and leukocyte count were frequently elevated. All the abscesses appeared as areas of hypodensity on CT scan and hypoechogenicity on ultrasonogram. The areas contained gas in the embolized tumor, which led to the suspicion and finally the diagnosis of abscess. In contrast to predominance of gram-negative aerobes in sporadic pyogenic liver abscesses, the causative microorganism was predominantly gram positive (60%). All patients were treated with parenteral antibiotics plus percutaneous aspiration, drainage, or operation, but one patient died from the abscess., Conclusions: For patients receiving TAE for HCC, few specific clinical or radiological features could readily differentiate patients complicated with liver abscess from those without. This may delay a timely diagnosis and lead to significant morbidity. Hence, in patients with risk factors, including old age, previous biliary tract disease, large tumor size (>5 cm), and gas forming in the embolized tumor, aspiration of the suspected focal hepatic lesion should be performed as soon as possible.

- Abstract
A series of 23 patients with intractible gastrointestinal (GI) bleeding were managed by the transcatheter method. The series included 5 with hemobilia, 8 with upper GI (UGI) bleeding, 5 with lower GI (LGI) bleeding and 5 with variceal bleeding. The etiology of the hemobilia was surgery, or percutaneous transhepatic cholangiography and drainage (PTCD) complicated by various degrees of biliary tract infection. The causes of UGI bleeding included erosive gastritis, gastric and duodenal ulcers, and traumatic duodenal laceration. All 5 LGI bleedings were due to ischemic colitis and all 5 variceal bleedings were due to hyperdynamic portal hypertension from arterio-portal (A-P) shunting for hepatocellular carcinomas (HCC). Intra-arterial vasopressin infusion was performed on 17 (4, hemobilia; 8, UGI; and 5 LGI bleeding) of these 23 cases as initial management. The success rate for vasopressin in hemobilia, UGI and LGI bleeding was 75% (3/4), 38% (3/8), and 60% (3/5), respectively. The overall initial success rate of vasopressin was 52% (9/17). The relatively poor success rate of vasopressin infusion for UGI bleeding was due to ulcers and laceration. The incidence of rebleeding for vasopressin infusion was 22% (2/9) including one case each of UGI and LGI bleeding. Three patients (1 hemobilia and 2 UGI bleeding) among these 17 cases underwent transarterial embolization (TAE) after failure of intra-arterial vasopressin infusion. One of these 23 cases with hemobilia underwent TAE for initial transcatheter control of the GI bleeding. Five cases of active esophageal variceal bleeding, caused by A-P shunting in HCC, were all successfully controlled by TAE.(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
Ten cases of large hepatocellular carcinoma (HCC) (largest diameter, 6.5-15 cm) were surgically resected from 3 to 19 days after transcatheter hepatic arterial embolization (TAE) for histologic assessment of the effectiveness. Another two patients, including one with a small HCC (3.5 X 3 X 3 cm) who died of complications, were also studied. The patients' ages ranged from 20 to 64 years, 11 were men and 1 was a woman, and all positive for serum hepatitis B surface antigen. All 11 cases with large HCC were symptomatic before the HCC was clinically diagnosed. Alpha-fetoprotein levels were elevated in ten cases but immediately dropped to normal levels after TAE and resection in eight cases. An effective massive tumor coagulative necrosis of 99% already occurred 3 days after TAE. A necrosis involving more than 95% of the whole tumor mass was demonstrated in eight cases: one was a large HCC taken from an autopsy specimen, and TAE was done three times. This strongly indicates the effectiveness of TAE on the destruction of HCC. However, the presence of viable residual tumors in 11 cases also strongly argues for the necessity for surgical resection whenever it is possible. The failure of a complete necrosis was related to the extracapsular extension, liver invasion, satellite nodules, and portal vein involvement, and probably related to collateral and portal vein blood supply.
