[CT guided percutaneous needle biopsy of mediastinal lymph nodes for staging of primary lung carcinoma].
In cases of primary lung carcinoma, diagnosis of metastatic mediastinal lymph nodes using computed tomography (CT) is usually difficult, and mediastinoscopy is highly invasive for patients. By using CT guided percutaneous needle aspiration technique, we diagnosed the metastasis to mediastinal lymph nodes in three cases of primary lung carcinoma. ⋯ Furthermore, biopsy of almost all mediastinal lymph nodes may be feasible by using both anterior and posterior approach. This method seems to be very useful for the diagnosis of the staging of primary lung carcinoma.

The case of a 56-year-old man who underwent mitral valve replacement due to HOCM complicated by IE and MR is reported. Preoperative 2D echocardiographic assessment of the mitral valve revealed systole anterior motion (SAM) and vegetation, and color flow Doppler echocardiographic examination revealed severe mitral regurgitation. The left ventricular out-flow tract gradient decreased from 140 mmHg preoperatively to 60 mmHg postoperatively. Mitral valve replacement should be considered in patients with associated IE and severe MR.
