Liver metastases from colorectal cancers: detection with CT during arterial portography.

A total of 45 metastases to the liver from colorectal cancer were resected in 22 patients. The detectability of these lesions with the following modalities was determined: real-time ultrasound (US), computed tomography (CT), selective celiac arteriography (SCA), infusion hepatic angiography (IHA), CT during arterial portography (CTAP), and CT following intraarterial injection of iodized poppyseed oil (Lipiodol). The total detection rate (sensitivity) was 58% for US, 63% for CT, 27% for SCA, 50% for IHA, 84% for CTAP, and 38% for CT with iodized oil. Ten of 18 lesions less than 15 mm in largest diameter were demonstrated preoperatively by CTAP only. CTAP is useful in clarifying the locations of the lesions in the liver and should always be performed before liver metastases from colorectal cancer are resected.

Therapeutic hepatic vein angioplasty for Budd-Chiari syndrome.

The authors report a case of Budd-Chiari syndrome treated by percutaneous transluminal angioplasty (PTA). In this case, the occlusion of three major hepatic veins with a big collateral to the inferior vena cava via the right inferior hepatic vein (RIHV) and stenosis of the ostium of RIHV were seen. We performed successful PTA of this stenosis.

Vestibular training after sudden loss of vestibular functions.

12 cases of unilateral labyrinthectomy, 3 cases of VIIIth nerve section, 22 cases of streptomycin sulfate infusion into the middle ear cavity and 8 cases of bilateral vestibular a-functions underwent vestibular training. Our training is very useful for regaining equilibrium and for evaluating the effects of training on equilibrium by recording the gravity center movements.

Segmental staining on hepatic arteriography as a sign of intrahepatic portal vein obstruction.

Peripheral obstruction of intrahepatic portal vein branches was detected by dynamic sequential computed tomography during arterial portography and subsequently confirmed surgically in 9 patients with hepatic neoplasm (7 hepatocellular carcinomas, 1 cholangiocarcinoma, and 1 metastatic lymphadenopathy from gastric carcinoma). In 1 patient, 2 obstructed segments were seen. Eight of these 10 segments showed more dense staining than other regions of the liver during infusion hepatic angiography. Retrograde opacification of the peripheral venules of the obstructed portion was seen in 2 of these 8 segments. This pattern was attributed to trans-sinusoidal or peripheral arterioportal shunting. In 5 cases, the segmental staining obscured the tumor stain, making the tumor appear larger than it actually was or causing it to be missed altogether.

Saccades--random or constant stimuli and predictive adaptability.

The influence of the predictive adaptability on saccades was studied in 20 normal subjects ranging in age from 18 to 43 years. The average velocity of random and constant saccades showed almost the same results. The maximum velocity of constant saccades was slightly faster than that of the random saccades. The latency of the random saccades was shorter than that of the constant ones. Thus, the predictive adaptability of the stimuli has little influence on the maximum velocity and on the latency of saccades in normal subjects.

Work in progress: dynamic sequential computed tomography during arterial portography in the detection of hepatic neoplasms.

Dynamic sequential computed tomography with table incrementation during arterial portography (DSCTI-AP) of the entire liver was performed in an attempt to improve the detection of hepatic neoplasms. In 13 of 17 patients, DSCTI-AP detected more hepatic lesions than were detected by other imaging methods, including radionuclide liver scans, ultrasound, computed tomography, and hepatic angiography. In only one case, an extremely hypervascular hepatocellular carcinoma, hepatic angiography was superior to DSCTI-AP. DSCTI-AP is a simple technique that may be carried out as a part of hepatic angiography. We believe that DSCTI-AP is a sensitive and useful method for the accurate detection of hepatic neoplasms.

Hepatocellular carcinoma involving the portal vein.

A case of hepatocellular carcinoma with invasion of the portal vein is reported. A tumor defect within the dilated portal vein is well demonstrated by computed tomography, and its appearance is compatible with the "thread and streaks" sign seen on hepatic angiography.
