The operative technique of a transcervical-subxiphoid-videothoracoscopic "maximal" thymectomy without sternotomy is described and the early results of the follow-up of patients operated on are analyzed. ⋯ We conclude that the "maximal" transcervical-subxiphoid-videothoracoscopic thymectomy is a safe operative technique, avoiding a sternotomy, performed partly in an open fashion with the extensiveness comparable with the transsternal extended and "maximal" thymectomies. The two-team approach helps to reduce the operative time. However, because of the limited time of follow-up it is too early for the final assessment of the long-term results of this method in the treatment of myasthenia gravis.

Use of profoundly hypothermic cardiopulmonary bypass may increase the risk of postoperative bleeding and lung and renal dysfunction. The aim of this study was to analyze postoperative blood loss and indices of pulmonary and renal dysfunction in patients undergoing proximal aortic surgery with and without the use of profound hypothermia to determine risk factors for nonneurologic morbidity. ⋯ Profound hypothermia may cause a coagulopathy, but procedure extent is the primary determinant of postoperative bleeding. Profoundly hypothermic cardiopulmonary bypass does not appear to be a risk factor for renal or early pulmonary dysfunction or intensive therapy unit length of stay.

Review Comparative Study
Off-pump epicardial tissue sealing--a novel method for atrioventricular disruption complicating mitral valve procedures.
Atrioventricular disruption (AVD) is a rare (1%-2%) but fatal complication after mitral valve procedures; the intraoperative mortality is more than 50% despite the current standard procedure of surgical closure of the defect. We compared the outcome of 9 patients with intraoperative AV disruption, 4 being surgically treated on-pump and 5 receiving epicardial tissue sealing off-pump. ⋯ Our data show that epicardial tissue sealing off-pump results in successful termination of bleeding from AVD and considerably improves survival when compared with the standard procedure. Because of this tremendous improvement in patient survival we now consider this technique as standard therapy for AV disruption in our center.

Satisfactory neurologic outcome following aortic arch repair through right brachial artery perfusion is well established. However, how neurocognitive functions are affected following selective cerebral perfusion, still needs to be elucidated. ⋯ The low-flow selective antegrade cerebral perfusion technique through the right brachial artery may safely be used for the great majority of patients undergoing aortic arch repair without causing deteriorations in neurocognitive functions.

The outcome in patients treated surgically for coronary artery disease is known to be influenced by the extent of the disease. Whether this factor also has an effect in patients undergoing isolated minimally invasive revascularization of the left anterior descending (LAD) artery using the internal thoracic artery (ITA) (MIDCAB) has not been looked at. Thus, this study sought to evaluate the impact of multivessel disease (MVD) on midterm outcome after MIDCAB. ⋯ Patients with isolated disease of the LAD appear to benefit from ITA grafting in the form of a MIDCAB procedure. Here, it should be an approach of choice. The results show that MVD is an independent risk factor for outcome in patients undergoing a MIDCAB procedure. Nevertheless, the midterm morbidity and mortality in MVD patients after a MIDCAB procedure where the LAD is the only target vessel for interventional or surgical treatment is acceptable despite a higher morbidity than in SVD patients.
