A 62-year-old man was admitted to the hospital because of massive hemoptysis. Chest X-ray film, CT scan and IADSA demonstrated a large aneurysm of the thoracic aorta, extending from the ascending aorta to the descending aorta. Bronchoscopy revealed bleeding from left B1+2. Six days after the onset, replacement of the thoracic aorta with woven Dacron prosthetic graft, autoclaved after immersion in albumin, was performed with cardiopulmonary bypass and separate cerebral perfusion (700 ml/min) under moderate hypothermia (25 degrees C). Left upper lobe of the lung, adherent tightly to the posterior and medial wall of the aneurysm, was not dissected because bleeding from left bronchus was trivial even after systemic heparinization. Because of the cardiac dilatation, delayed chest closure was needed. Postoperative cardiac failure, necessitating much catecholamine support, was seen with gradual improvement and no neurological deficit was recognized. He was discharged from the hospital without any sequelae 2 months after the onset. Pathologic diagnosis was an atherosclerotic aneurysm.

We report a rare case of hydatidosis of the right heart. Our young patient had know pulmonary hydatidosis and presented precordial chest pain, increasing dyspnea, cough and hemoptysis. Echocardiography, confirmed by angiocardiography delineated the right ventricular cyst. The operation was performed under extra corporal circulation (ECC), moderate hypothermia with cold cardioplegia. The echinococcal cyst was removed after local instillation of 0.5% silver nitrate solution. The postoperative course was uneventful.

Six cases of pulmonary artery perforation associated with the use of Swan-Ganz catheters are reviewed. Risk factors included pulmonary hypertension, anticoagulation, and hypothermia. The mechanisms leading to perforation were clarified by the use of postmortem studies employing isolated whole lung preparations. These studies revealed that perforation results from (1) tip perforation of vasculature, (2) eccentric balloon configuration propelling the balloon through the vessel wall, and (3) balloon inflation disrupting the pulmonary artery (mean intraballoon pressure 250 mm Hg). Early clinical symptoms include hemoptysis of bright red blood and/or hypotension. Immediate evaluation may necessitate examination with a fiberoptic bronchoscope and "wedge" angiogram. If massive hemoptysis occurs, isolation of the unaffected lung by endobronchial intubation is mandatory. Pneumonectomy or lobectomy may be required. Revised guidelines for catheter insertion and pulmonary capillary wedge pressure (PCWP) measurements are presented. Finally, consideration is given to redesigning the pulmonary artery flow-guided catheter, particularly for use in patients undergoing cardiac operations with systemic anticoagulation. Modifications should be directed at (1) softer catheter tip with temperature-insensitive body, (2) low-pressure balloon, and (3) balloon pressure relief valve.

From January 1989 to September 1993, 59 consecutive patients (35 males and 24 females, mean age 59.6 years old) underwent surgical repair of aortic dissection on the cardiovascular surgical unit at Takeda Hospital. The type of aortic dissection were classified according to Stanford University criteria. Twenty-two patients had acute type A (Ac-A), 10 had chronic type A (Ch-A), 4 had acute type B (Ac-B), and 23 had chronic type B (Ch-B) dissection. Seventeen dissections (29%) in the entire group of 59 cases had ruptured (including cardiac tamponade, pleural effusion and hemoptysis etc.). Ischemia of lower extremity occurred in 7 patients and ischemia of visceral organs in 3 patients. Type A dissection were approached via a median sternotomy and cardiopulmonary bypass with systemic hypothermia. Type B dissections were approached through a left postrolateral thoracotomy. Left heart bypass (left atrial-femoral in 8 cases) and partial cardiopulmonary bypass (femoral-femoral in 12 cases) generally were utilized. Resection of intimal tear and replacement of aorta with vascular grafts (including aortic arch in 19 cases) were performed in most patients and primary closure of the intimal tear was performed in 9 cases using GRF. The over-all operative mortality rate was 36% (8/22) for Ac-A, 20% (2/10) for Ch-A, 25% (1/4) for Ac-B, 22% (5/23) for Ch-B. Main causes of operative death was perioperative brain damage. It is necessary to improve the operative mortality for Ac-A dissections (especially in replacement of aortic arch and arch vessels). Further researches are needed regarding optimal methods of the cerebral protection during reconstruction of aortic arch.

Two case reports describing patients having cardiac operations under extra corporeal circulation are presented. At the completion of the operation, a massive hemoptysis occurred in both patients after a Swan-Ganz catheter had perforated the pulmonary artery. A hemostasis lobectomy was then immediately required. The immediate and long term prognosis seems satisfactory. This is an unusual but serious complication. The incidence of this complication varies between 0.06 and 0.2%. The more frequently related risk factors include people over the age of 60, pulmonary artery hypertension, anticoagulant therapy, hypothermia and manipulation of the heart by the surgeon. When this accident occurs, many authors suspect the balloon. An early diagnosis is essential in the case of a major or even a minor hemoptysis, because this complication may be a lethal one as the mortality rate may reach 50%. According to us, the appropriate therapy which would reduce this mortality is a surgical one (hemostasis lobectomy).

A 78-year-old woman was admitted to our hospital with intermittent hemoptysis. She had undergone descending aortic replacement through a left thoracotomy 7 years previously. Enhanced computed tomography revealed a pseudoaneurysm at the proximal suture line in the descending aorta and an ascending aortic aneurysm. Bronchoscope revealed bleeding from the left lower bronchus. Ascending and total aortic arch replacement and simultaneous open stent-graft placement into the descending aorta were performed through a median sternotomy. Selective antegrade cerebral perfusion and moderate hypothermia were used during these procedures. The postoperative course was favorable. Open stent-graft placement is a good alternative for treating aortobronchial fistula caused by suture line pseudoaneurysm in the descending aorta.

The patient was a 41-year-old female with chronic thromboembolism. She was admitted to an affiliated hospital with exertional dyspnea, leg swelling, and hemoptysis, and she was treated medically with tissue plasminogen activator and warfarin therapy. When transferred to our hospital, she was oxygen-dependent with severe dyspnea. A pulmonary arteriogram showed occlusion and stenosis of the pulmonary arteries. Cardiac catheterization revealed marked pulmonary hypertension. The lung perfusion scintigram showedmultiple defects in the right and left lungs. Preoperative laboratory data showed a markedly decreased protein C antigen level. Magnetic resonance angiography showed that a myoma uteri compressed the pelvic vein and that she had deep vein occlusion of the left leg. After the administration of an epoprostenol infusion and the insertion of an inferior vena cava filter, she underwent an operation. Under deep hypothermia, the bilateral pulmonary artery was opened and an endarterectomy was performed during intermittent circulatory arrest. After surgery, her pulmonary vascular resistance was in the normal range. Her New York Heart Association functional classification changed from class IV to class I. She has been in good condition for 7 years since the surgery.
