Abstract

The practical limitations of catheters used for infusion were studied by their types in 47 patients with hepatocellular carcinoma who were treated by Segmental Lp-TAE. For catheterization into the arterial branches of S5 and S8, a coaxial infusion catheter was helpful. However, a coaxial infusion catheter was seldom used for catheterization into the arterial branches of S6 and S7. For infusion into vessels having diameters of less than 1.9 mm at the tip end of the catheter, positive use of a coaxial infusion catheter is strongly recommendable. A Tracker-18 catheter was especially helpful for catheterization into the vessels of S5.

Abstract

A biliary endoprosthesis constructed of Gianturco self-expanding metallic stents was placed in twenty-nine patients with obstructive jaundice, 27 malignant and 2 benign. All endoprostheses were placed successfully. External drainage catheters were removed in twenty-seven patients. At the follow-up, ranging from two to 59 weeks, the 30 day mortality rate was 7.4%. Twenty-eight patients had obvious clinical improvement with relief of jaundice. Seven patients experienced recurrent jaundice. In two of these patients, the obstruction was relieved by additional metallic stents. The expandable metallic biliary endoprosthesis is suggested as an effective treatment for biliary obstruction.

Abstract

Expandable metallic stents were inserted to treat malignant obstructive jaundice in 4 patients and no migration was noted. In 2 patients, all stents expanded sufficiently enough to remove the external drainage and remained patent. A relatively small caliber (7 Fr) was needed for the introduction of the stent, and when the stent was released, it acquired a much larger diameter. The expandable metallic stent could be used for the effective treatment of obstructive jaundice.

Abstract

The evaluation of TAE was studied for 73 patients with metastatic liver cancers but without metastasis in other organs, who were treated with initial TAE more than 2 years ago. Seventeen patients survived for more than 2 years. The primary lesions consisted of colon cancer in 9 patients, the Langerhans islet cell tumor of the pancreas in 4, gastric cancers in 2, breast cancer in 1 and leiomyosarcoma of the colon in 1. The overall 2-year survival rate calculated by the direct method was 23.3% and mean survival period was 15.8 months. The prognosis was good in H1 and V3. Lp-TAE produced better effects but no statistically significant difference was found between the 2-year survivals by Lp-TAE and by GS-TAE.

Abstract

The usefulness of MRI (magnetic resonance imaging) was evaluated in the diagnosis of the mediastinal invasion of esophageal cancer. MR examination was performed in 30 subjects without esophageal diseases and 23 patients with esophageal cancer. Normal esophagi and cancers were well visualized using T1-weighted image. In the axial section, every normal esophagus was contact to the aorta in the angle of less than 30 degree of the aortic circle. When the contact angle was less than 30 degrees, the stage of the cancer was below a1. When the angle was 30 degrees or greater, the stages were ranged from a0 to a3. In the oblique section orthogonal to the contact plain between the cancer and the aorta, the depth of the aortic invasion could be estimated. The sagittal scan was also helpful in the diagnosis of the invasion to trachea, left main bronchus and left atrium.

7. [The usefulness of motion artifact suppression technic (MAST) in the MRI diagnosis of liver tumors]

Abstract

The usefulness of motion artifact suppression technique (MAST) in the MRI diagnosis of liver tumors was assessed. Spin-echo with MAST was superior in lesion detection and contrast-to-noise ratio to conventional spin-echo. Its usefulness was verified. As the portal vein is delineated frequently as a high signal area, the portal structure up to the third branches was distinctly visualized. It was found helpful for the segmental diagnosis of the liver. However, careful attention is needed in the diagnosis of portal vein thrombosis.

Abstract

Correlation between cortico-medullary contrast (CMC) and dynamic CT or MRI for chronic renal parenchymal diseases was evaluated compared with serum creatinine level (Cr). Forty two kidneys of 23 patients were chronic glomerulonephritis (12), chronic pyelonephritis (12), chronic renal failure (4), and other diseases (14). Thirty two kidneys with low Cr (under 1.6) were demonstrated the good CMC by dynamic CT and T1-weighted image (IR) of 0.5 T. Six with middle of Cr (between 1.6 and 3.0) were showed a decrease in CMC and four with high Cr (over 3.0) had no CMC. CMC correlated with Cr.
