Case ReportsSeptal myectomy, papillary muscle resection, and mitral valve replacement for hypertrophic obstructive cardiomyopathy: a case report.
We report a case of hypertrophic obstructive cardiomyopathy (HOCM) successfully treated with septal myectomy and mitral valve replacement (MVR) combined with a resection of the hypertrophic papillary muscles. The patient, a 74-year-old woman, first underwent the conventional septal myectomy through aortotomy. The papillary muscles revealed a marked hypertrophy, but extended myectomy and precise resection of the hypertrophic papillary muscles were thought to be difficult through the aortotomy. ⋯ The patient has been doing well in the New York Heart Association (NYHA) functional class between I and II during 45 months of follow-up, without complications related to the use of a prosthetic valve. Septal myectomy is the procedure of choice in the surgical treatment of HOCM for most cases, but some may require additional mitral valve procedures. In patients with marked hypertrophic papillary muscles, MVR and resection of the muscles may be an option of treatment to ensure a relief of the outflow obstruction and to abolish systolic anterior movement in units with limited experience.

Comparative StudyAnalyzing the outcome of early versus prolonged extubation following cardiac surgery.
This study considered the factors associated with prolonged ventilation and the effects of reduced extubation times on patient recovery, intensive care unit stay, and overall hospital stay. ⋯ Early extubation offers a substantial advantage in terms of accelerated recovery, shorter intensive care unit, and hospital stay, suggesting that efforts to reduce extubation times are cost-effective.

Spontaneous hemopneumothorax is a rare clinical disorder that results from a torn small vessel located in adhesions between the visceral and parietal pleurae resulting from the progress of lung collapse. A large spontaneous hemopneumothorax is often life threatening, so the late recognition and delayed intervention can increase mortality rate. ⋯ We are reporting 17 patients with spontaneous hemopneumothorax to emphasize the following: (i) the mechanism of spontaneous hemopneumothorax, which was caused by a torn pleural adhesion band resulting from the lung collapse. The collapse was developed mainly by an air leak from ruptured bullae, and rarely by additional pressure from the outside during a drainage procedure. (ii) The importance of early recognition and prompt surgical intervention by VATS or thoracotomy. We preferred VATS to thoracotomy because it is easier to access the bleeding point near the Sibson's fascia by VATS, and it can reduce the loss of blood by relatively shorter operating time.

ReviewThe methodologies of hypothermic circulatory arrest and of antegrade and retrograde cerebral perfusion for aortic arch surgery.
In spite of recent advances in thoracic aortic surgery, postoperative neurological injury still remains the main cause of mortality and morbidity after aortic arch operation. The use of cardiopulmonary bypass (CPB) and hypothermic circulatory arrest, temporary interruption of brain circulation, transient cerebral hypoperfusion, and manipulations on the frequently atheromatic aorta all produce neurological damages. The basic established techniques and perfusion strategies during aortic arch replacement number three: hypothermic circulatory arrest (HCA), antegrade cerebral perfusion (ACP), and retrograde cerebral perfusion (RCP). ⋯ HCA combined with ACP, however, could prolong safe brain-ischemia time up to 80 min. Cold ACP at 10 degrees -13 degrees C should be initially applied through the right subclavian or axillary artery and continued bihemispherically through the left common carotid artery at first and later the anastomosed graft, with a mean perfusion pressure of 40-70 mm Hg. The safety of temporary perfusion is being confirmed by the meticulous monitoring of brain perfusion through internal jugular bulb O2 saturation, electroencephalogram, and transcranial comparative Doppler velocity of the middle cerebral arteries.

Case ReportsThoracic empyema and lung abscess resulting from gastropulmonary fistula as a complication of esophagectomy.
A benign fistula between the gastric tube and the airway resulting from esophagectomy is a rare complication, but it is a potentially life-threatening status. We present a 59-year-old man with thoracic empyema and lung abscess resulting from a benign gastric tube-to-pulmonary fistula caused by a penetration of the peptic ulcer in the gastric tube four years after an esophagectomy for esophageal cancer. ⋯ The postoperative course was uneventful. Two years and nine months later, the patient retains satisfactory oral feeding status and is in good general condition.
