In addition to variceal bleeding, haematemesis may occur due to haemorrhagic gastritis in patients with portal hypertension. This has been known as portal hypertensive gastropathy (PHG). We have evaluated the effects of the transjugular intrahepatic portosystemic shunt (TIPS) on portal venous pressure (PVP) and endoscopic gastric mucosal changes observed in patients with portal hypertension. We performed TIPS in 12 patients with complications due to portal hypertension as follows: variceal bleeding in nine patients (bleeding from oesophageal varices in seven and gastric varices in two), refractory ascites in three and haemorrhage from severe PHG in one. Endoscopic examinations were performed before and after TIPS for all patients. Changes of PVP and gastric mucosal findings on endoscopy were analysed. Before TIPS, PHG was seen in 10 patients. Portal venous pressure decreased from an average of 25.1+/-8.8 to 17.1+/-6.2 mmHg after TIPS (P<0.005). On endoscopy, PHG improved in nine of 10 patients. Oesophagogastric varices improved in eight of 11 patients. In one patient with massive haematemesis, haemorrhage from severe PHG completely stopped after TIPS. Because TIPS effectively reduced PVP, this procedure appeared to be effective for the treatment of uncontrollable PHG.

Seventy-six patients with persistent myelopathy secondary to chronic spinal cord injuries underwent examination with magnetic resonance (MR) imaging, the results of which were correlated with neurologic findings. Twenty-one patients received follow-up study during and after the acute stage; 55 patients were examined only at a chronic stage. Spinal cord abnormalities were seen in 48 patients according to five patterns: (a) normal signal intensity on T1- and T2-weighted images (pattern N/N, n = 28), (b) normal signal intensity on T1-weighted and hyperintensity on T2-weighted images (pattern N/Hi, n = 18), (c) hypointensity on T1-weighted and hyperintensity on T2-weighted images (pattern Lo/Hi, n = 17), (d) cord atrophy (n = 5), and (e) longitudinal syrinx formation with hypointensity on T1- and hyperintensity or isointensity on T2-weighted images (n = 8). Patients with pattern N/N had only slight neurologic damage and an excellent prognosis. Patients with pattern N/Hi had mild neurologic impairment, frequently associated with cord compression. Patients with pattern Lo/Hi had the worst prognosis. Atrophy was observed in patients with a long history of myelopathy.

A 66-year-old man was admitted to our hospital with right hemiplegia due to a cerebral infarction associated with Takayasu arteries. We successfully performed percutaneous transluminal angioplasty for stenoses of the innominate and right common carotid arteries. Improvement of the stenotic lesions persisted over 10 years.

Primary cardiac lymphoma (PCL) is a rare entity that leads to fatal symptoms such as serious arrhythmia. The present case was an 80-year-old female with severe dyspnea caused by 30 bpm bradycardia. Computed tomography revealed a tumor invading to the right inferior myocardium. A computed tomographic coronary angiography (CTCA) study revealed the right coronary artery penetrating the tumor with no invasion by the surrounding tumor. Because a percutaneous biopsy was unsuccessful, video-assisted thoracic surgery (VATS) was performed. The final pathological diagnosis was diffuse large B cell lymphoma. Rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) chemotherapy reduced the size of the tumor, and the symptoms thereafter improved. An observation of the coronary artery penetrating the tumor without tumor invasion may be a characteristic finding of PCL. CTCA is useful to detect this finding. When a percutaneous biopsy is unavailable, VATS should be considered as a minimally invasive procedure to obtain a reliable diagnosis of PCL.
