A triple coaxial catheter system for subselective visceral artery catheterization and embolization: preliminary clinical experience.
We developed a triple coaxial catheter system (TCCS) which consists of a 6.1 Fr outer, a 4.1 Fr intermediate, and a 3.0 Fr inner catheter, all coated with a lubricant. The TCCS was used in seven patients with hepatic tumors, after several attempts to access a targeted vessel with conventional catheters and guidewires failed to reach the targeted vessel. No complications were encountered with the use of this system. TCCS may be a useful device for selective abdominal arteriography.

Hepatocellular carcinoma extending into the portal vein: restoration of extended-term patency by placement of uncovered Wallstents.
A 74-year-old man presented with hepatocellular carcinoma extending into the main portal vein. Two bare Wallstents were placed to maintain portal vein patency. The main portal vein remained patent for 6 months after treatment. No serious complications were observed during or after treatment.

Tumor marker and MR imaging criteria for evaluating the efficacy of cyclic balloon-occluded arterial infusion for advanced cancer of the uterine cervix.
We have already reported satisfactory therapeutic results of cisplatin-based cyclic balloon-occluded arterial infusion chemotherapy (BOAI) enabling treatment by simple total hysterectomy (STH) in patients with advanced cervical cancer of the uterus (cervical cancer), with 2- and 5-year survival rates of 88.9% and 66. 7%, respectively. Considering the fact that 3 to 4 months are needed to complete BOAI, the present study was a retrospective assessment of 18 cervical cancer patients to prepare criteria for the early determination of the efficacy of BOAI in patients who can be treated by STH. The results showed that STH could be performed after the first BOAI in patients with SCC value decreased to 34.3+/-8.2% of the pretreatment value (p=0.0001) and whose tumor size had decreased by 45.1+/-7.5% (p=0.0002).

A case of Budd-Chiari syndrome successfully treated by transcatheter recanalization of the right hepatic vein and transjugular intrahepatic portosystemic shunt.
A 40-year-old man with Budd-Chiari syndrome due to chronic obstruction of the major hepatic veins was successfully treated by interventional radiologic procedures. Initially, partial splenic embolization was performed to improve thrombocytopenia and coagulopathy of blood. Second, recanalization was done by thrombolic therapy. Finally, the TIPS procedure was carried out through the recanalized right hepatic vein. This resulted in great improvement of Budd-Chiari syndrome, a marked decrease in pressure, and disappearance of gastroesophageal varices on endoscopy.

The hemodynamics of dysplastic nodules in the liver evaluated by CT angiography and immunohistochemistry.
BACKGROUND/AIMS: Dysplastic nodules diagnosed pathologically exhibit various hemodynamic patterns. To evaluate these differences in their hemodynamics, we observed basement membrane formation of sinusoids. METHODOLOGY: For 12 low-grade dysplastic nodules, 24 high-grade dysplastic nodules and 16 hepatocellular carcinomas, both computed tomography during arterial portography and CT arteriography were performed preoperatively. Resected specimens were examined immunohistochemically for COL IV (type IV collagen) and laminin to observe basement membrane formation. We compared their hemodynamics on computed tomography during arterial portography and CT arteriography with the expressions of COL IV and laminin. RESULTS: All of the low-grade dysplastic nodules were not hypervascular on CT arteriography, and negative for COL IV and laminin. All of the hepatocellular carcinomas were hypervascular on CT arteriography, and positive for COL IV and laminin. High-grade dysplastic nodules exhibit four hemodynamic patterns on CT during Arterial Portography/CT arteriography. All of 7 iso/iso and 5 iso/hypo nodules were negative for COL IV and laminin. Of the 9 hypo/hyper nodules, which exhibited hemodynamics similar to hepatocellular carcinoma, COL IV was identified in 7 and laminin identified in 8 nodules. Of the 3 hypo/hypo nodules, COL IV and laminin were identified in one. CONCLUSIONS: In high-grade dysplastic nodules, most cases exhibited a correlation between the hemodynamic patterns and the degree of the sinusoidal basement formation.
