Methods Five patients diagnosed as inferior, right ventricular, and anteroseptal walls AMI at admission were enrolled. Electrocardiographic data and results of isotope ^99mTc-methoxyisobutylisonitrile (MIBi) myocardial perfusion imaging and coronary angiography (CAG) were analyzed. Results Electrocardiogram showed that ST segment significantly elevated in standard leads Ⅱ, Ⅲ, aVF, and leads V1-V3, V3R-V5R in all five patients. The magnitude of ST segment elevation was maximal in lead V1 and decreased gradually from lead V1 to V3 and from lead V1 to V3R-V5R. There was isotope ^99mTc-MIBI myocardial perfusion imaging defect in inferior and basal inferior-septal walls. CAG showed that right coronary artery was infarct-related artery. Conclusions The diagnostic criteria for basal inferior-septal wall AMI can be formulated as follows: ( 1 ) ST segment elevates ≥2 mm in lead V1 in the clinical setting of inferior wall AMI; (2) the magnitude of ST segment elevation is the tallest in lead V1 and decreases gradually from lead V1 to V3 and from lead V1 to V3R-V5R. With two conditions above, the basal inferior-septal wall AMI should be diagnosed.展开更多

Intraventricular cavernomas of the body of the lateral ventricle are usually treated by the transcallosal approach. Clinical Presentation: We present a case of a fifty-eight year old man with a septum pellucidum cavernoma successfully treated operatively by means of the inferior parietal transcortical transventricular approach. This unusual and scarcely documented tumor was situated at the posterior third of the septum pellucidum. The patient had a good recovery with no focal deficit. Conclusion: Septum pellucidum cavernomas are extremely rare lesions. Inferior parietal transcortical approach is a safe alternative to the commonly used transcallosal approach for lesions of the posterior half of the septum pellucidum.展开更多

The most common approach of the procedure is via femoral vein. However, when the inferior vein cava is interrupted or obstructed, it is unfeasible to carry out the procedure via femoral vein. So an alternative approach such as internal jugular vein or subclavian vein needs to be considered.展开更多
