Haemodynamic and EKG changes in patients undergoing minimally invasive direct coronary artery bypass.

Background And Objectives: The objective of the report is to monitor, in patients undergoing minimally invasive direct coronary artery bypass surgery (MIDCAB), the haemodynamic parameters, ST segment changes and the incidence of arrhythmias during clamping of the coronary artery and following reperfusion.

Methods: Twelve patients scheduled for elective MIDCAB surgery during isoflurane anesthesia were enrolled in the study. Patients were monitored by a pulmonary artery thermodilution catheter, an arterial line and 5 leads ECG.

Minimally invasive axillary-LAD saphenous vein bypass.

The left internal mammary artery (LIMA) is the arterial conduit of choice for minimally invasive coronary bypass to the left anterior descending (LAD). However, in redo cases when the LIMA is not available, the use of a saphenous vein graft as an extra-anatomic bypass from the axillary artery to the LAD offers a lower risk alternative than conventional reoperative trans-sternal surgery [Knight 1997]. We report on 3 patients who underwent axillary-LAD saphenous vein bypass.

Fine-needle aspiration of the mediastinum: a clinical, radiologic, cytologic, and histologic study of 42 cases.

Forty-two fine-needle aspirates (FNA) of the mediastinum were reviewed from 1984-1995. The clinical, radiologic, pathologic, and cytologic material was studied. Twenty-five males and 17 females had an age range from 10-72 yr and a mean of 41 yr.
