[Experimental and clinical study of cardiopulmonary hemodynamics under one-lung ventilation during transthoracic esophagectomy].
Cardiopulmonary hemodynamics in pre- and postoperative period after transthoracic esophagectomy under one-lung ventilation (OLV) was investigated in experimental and clinical studies. In experimental study, 30 mongrel dogs were assigned to one of the groups: Group 1 (n = 10): 2 hour right thoracotomy alone under one (n = 5)- or two-lung ventilation (TLV) (n = 5), Group 2 (n = 10): thoracotomy + esophagectomy, Group 3 (n = 10): esophagectomy + right thoracic vagotomy. For further evaluation of the effect of vagotomy on increase of extravascular lung water (EVLW) on 3rd POD, the following 2 groups were designed as Group 4-1) (n = 5): thoracotomy + right thoracic vagotomy and Group 4-3) (n = 5): esophagectomy + left thoracic vagotomy. ⋯ Cardiopulmonary parameters and postoperative complications were not different between OLV and TLV groups in clinical study. In conclusion, OLV is a desirable procedure, not only for good exposure of the operative filed, but also for its safety regarding the cardiopulmonary hemodynamics. Transthoracic esophagectomy plus vagal branch denervation, which is necessary for aggressive lymphadenectomy around the trachea, increases EVLW and subsequent pulmonary edema compared with thoracotomy alone.

Case Reports[Traumatic rupture of the diaphragm--a case of lung herniation into the abdominal cavity].
A first case of lung herniation into abdominal cavity with traumatic diaphragmatic rupture is described. A 41-year-old Japanese man with chronic obstructive pulmonary disease suffered traumatic diaphragmatic rupture. ⋯ At the time of operation, left lung herniation into the abdominal cavity was observed. When those who have chronic obstructive pulmonary disease suffered thoraco-abdominal injury, we should take care that pulmonary herniation might exist.

Case Reports[MRSA pyothorax due to bronchopleural fistula after grafting and pneumonectomy for traumatic aneurysm of the thoracic aorta--a successful treatment by open drainage and omentopexy].
Treatment of postpneumonectomy pyothorax due to bronchopleural fistula (BPF) is troublesome, especially with methicillin-resistant staphylococcus aureus (MRSA) infection. Moreover, in a bypass-grafting case, the management becomes more complicated. We reported a successful treated case of MRSA pyothorax due to BPF after grafting and pneumonectomy. ⋯ Therefore, open pleural drainage underwent. At the same time, bronchial stump and graft surface was covered with the omental pedicle flap. The open wound had become sterile in two months, and the thoracic window was closed three months after the open drainage.

Review Case Reports[Valve replacement in a patient with infective endocarditis and ruptured mycotic cerebral aneurysm].
A 55-year-old man with a mild fever and sweating developed severe headache for the days before admission. Cerebral computed tomography and selected cerebral angiography on the day of admission revealed subarachnoid hemorrhage due to rupture of an aneurysm of a distal branch of the left middle cerebral artery. Detection of vegetation on the aortic valve by two dimensional echocardiography confirmed the diagnosis of infective endocarditis with a ruptured mycotic cerebral aneurysm. ⋯ Repeated cerebral angiography revealed that the aneurysm was becoming progressively smaller during the next 9 months. No cerebrovascular accident occurred postoperatively. We believe that it is safe to treat a ruptured mycotic cerebral aneurysm without involvement of a hematoma mass in the brain conservatively, and that use of a bioprosthetic valve, if valve replacement is mandatory, and avoidance of anticoagulant therapy during the postoperative period are advisable in the treatment of a patient with infective endocarditis and a ruptured cerebral mycotic aneurysm.

[Clinical and experimental study of the production of renal hemodynamic effects of IABP-assisted pulsatile flow extracorporeal circulation].
Renal hemodynamics during IABP-assisted pulsatile flow extracorporeal circulation was assessed in terms of measurement values for intraoperative renal blood flow obtained by the local thermodilution method in human clinical patients. In addition, the effect of IABP on renal hemodynamics was investigated in an animal model of renal denervation in a study undertaken to elucidate the action mechanism of IABP. Eighteen patients with acquired heart disease were involved in the study and measured for the renal blood flow (RBF), cardiac output (CO), renal-systemic partition coefficient for blood flow (RBF/CO), renal vascular resistance (RVR) and perfusion pressure. ⋯ Following a loading dose of noradrenaline (Norad), the RVR increased in a Norad concentration-dependent fashion, independently of IABP and renal denervation. These results indicate that IABP reduces the RVR and thereby exerts a favorable action on renal hemodynamics during pump times. The study thus warrants us to surmise that a mechanism involving the renal sympathetic nerves might play an important role in the production of favorable renal hemodynamic effects of IABP-assisted pulsatile flow extracorporeal circulation.
