Transjugular intrahepatic portosystemic shunt in a patient with cavernomatous portal vein occlusion.

A 23-year-old woman with liver cirrhosis secondary to primary sclerosing cholangitis was referred to us for the treatment of recurrent bleeding from esophageal varices that had been refractory to endoscopic sclerotherapy. Her portal vein was occluded, associated with cavernous transformation. A transjugular intrahepatic portosystemic shunt (TIPS) was performed after a preprocedural three-dimensional computed tomographic angiography evaluation to determine feasibility. The portal vein system was recanalized and portal blood flow increased markedly after TIPS. Esophageal varices disappeared 3 weeks after TIPS. Re-bleeding and hepatic encephalopathy were absent for 3 years after the procedure. We conclude that with adequate preprocedural evaluation, TIPS can be performed safely even in patients with portal vein occlusion associated with cavernous transformation.

A case of hepatocellular carcinoma with the sign of Leser-Trelat: a possible role of a cutaneous marker for internal malignancy.

A rare case of hepatocellular carcinoma who developed the complication of the sign of Leser-Trelat is reported. The patient, a 57-year-old male, visited our hospital with complaints of generalized malaise and anorexia. A diagnosis of hepatocellular carcinoma was made based on elevated alpha-fetoprotein measurement, ultrasonography, and hepatic arteriography findings. Chest x-ray film suggested pulmonary metastases of hepatocellular carcinoma. Thereafter, complications of the seborrheic keratosis developed in the trunk and the skin lesion was diagnosed as the sign of Leser-Trelat associated with hepatocellular carcinoma. The patient died of pneumonia 9 months after development of the sign of Leser-Trelat.

Effect of iohexol and diatrizoate on pulmonary arterial pressure following pulmonary angiography. A clinical comparison in man.

A clinical comparison of the effects on pulmonary arterial pressure produced by iohexol and diatrizoate, following selective pulmonary angiography, was made in 17 patients with a normal pressure before the injection of the contrast medium. A double blind crossover study was performed and each contrast medium was administered in random order. The pulmonary arterial pressure was continuously recorded before, during and after the injection for 3 minutes. The effect of iohexol on the pulmonary arterial pressure was significantly less than that of diatrizoate. The results indicated that iohexol should be better tolerated than diatrizoate and therefore a safer contrast medium for selective pulmonary angiography.

Effect of iohexol on pulmonary arterial pressure at pulmonary angiography in patients with pulmonary hypertension.

The effects of 300 mgI/ml of iohexol on pulmonary arterial pressure at selective pulmonary angiography were evaluated in seven patients with pulmonary hypertension due to pulmonary thromboembolism. The total number of contrast injections was 26. Pulmonary arterial pressure was recorded before and after each injection. The effect of iohexol on pulmonary arterial pressure in the pulmonary hypertensive circulation was slight. The results suggest that iohexol at 300 mgI/ml may be safe as a contrast medium for selective pulmonary angiography in patients with pulmonary hypertension.

Anterior mediastinal schwannoma: a case report.

The most common neoplasms of the mediastinum are those of neurogenic origin, and the majority of these arise in the posterior compartment. We report a case of benign schwannoma originating in rare location, the anterior mediastinum, and its imaging findings.

Rotational digital angiography of ulcer-like projection of pelvis.

Ulcer-like projection is an angiographic sign of thrombosed aortic dissection. However, no pelvic manifestation of ulcer-like projection of aortic dissection has been reported. We report three patients in whom ulcer-like projections of the pelvic artery were revealed by rotational digital angiography using the newly developed computerized dynamic stereo-radiography apparatus.

Transcatheter arterial embolization as treatment for life-threatening maxillofacial injury.

A rare case of massive maxillofacial hemorrhage, which was controlled by transcatheter arterial embolization, is reported. A 23-year-old man with massive nasal and oral hemorrhage caused by maxillofacial fracture was admitted. Emergency angiography demonstrated extravasation of contrast material from the posterior superior alveolar artery, which was immediately embolized using gelatin sponge particles. This case shows that transcatheter arterial embolization is useful and effective for the treatment of massive hemorrhage resulting from severe maxillofacial injury.

Distal pancreatectomy--does it have a role for pancreatic body and tail cancer.

BACKGROUND/AIMS: Pancreatic resection is the only hope for clinical improvement for patients with carcinoma of the body and tail of the pancreas. However, it is unclear whether palliative pancreatic resection is effective or not for patients with carcinoma of the body and tail of the pancreas. METHODOLOGY: To determine the appropriate treatment for patients with pancreatic body and tail cancer, we analyzed the records of 74 patients with ductal carcinoma of the body or tail of the pancreas who were treated at Kanazawa University Hospital between 1970 and 1995. RESULTS: Using a multivariate Cox proportional-hazard model (factors: age, sex, chemotherapy, radiotherapy, hepatic metastasis, peritoneal dissemination, operative procedure), the presence of hepatic metastasis, peritoneal dissemination, and the type of operative procedures (resection or not) were found to be significant prognostic factors. Surgical resection was the most important prognostic factor. The patients with surgical resection had a significantly higher survival rate than those without resection (p < 0.0001). The survival rate of the patients with palliative resections was also significantly higher than that of the patients without resection, except for the patients with advanced liver metastasis (H3). The survival rate of the patients with palliative resections was also higher than that of the patients without resection, even in patients with peritoneal dissemination. CONCLUSIONS: Surgical resection prolongs the average survival for patients with carcinoma of the body and tail of the pancreas, except for the patients with multiple liver metastasis. These data support the role of palliative pancreatectomy in patients with carcinoma of the body and tail pancreas.
