Surgical treatment of solitary pulmonary metastasis.

Seventeen patients undergoing pulmonary excision for metastatic tumors of the lung from 1965 to 1975 are reviewed with an overall four-year survival of 72%. From this group, four patients are alive five years and more after operation. In two patients however, multiple metastases in the contralateral lung and bones have appeared. One of them underwent a second removal of metastatic tumor in the other lung. On the basis of this limited experience and the one reported in the literature, we believe that excision of pulmonary metastasis in selected cases improve the prognosis of those patients, prolong life, and in some cases may even result in cure of the basic disease.

Haemopericardium as a late complication in anticoagulant therapy following mitral valve replacement.

Two patients, who suffered from pericardial tamponade in the course of prophylactic anticoagulant treatment, are reported. The mitral valve had been replaced by a prosthesis in both cases. The diagnosis was suspected clinically and radiologically and proven by pericardiocentesis. One of the patients was treated by a percutaneously inserted small polyethylene tube for continous drainage and the other by thoracotomy and partial pericardiectomy. Both patients recovered and are at present asymptomatic. Th mechanism of bleeding patients receiving anticoagulant therapy is briefly discussed.

Mitral stenosis with pulmonary hypertension. Long-term results after mitral valvotomy.

Ten patients suffering from tight mitral stenosis with severe pulmonary hypertension were operated on and followed up for one to nine years after operation. There was no operative or postoperative mortality. Postoperative hemodynamic studies were performed on seven of the 10 patients. One patient was evaluated twice--one month and seven months after surgery. The condition of all patients improved after operation and regression of severe to extreme pulmonary hypertension was documented in the seven patients on whom the hemodynamic studies were repeated. Hemodynamic and clinical improvement was greatest in young patients with a shorter duration of disease and a normal sinus rhythm prior to operation. The results indicate that a severe degree of pulmonary vascular resistance in mitral stenosis is largely reversible, provided that the obstruction is adequately relieved.

Ureteral substitute by fallopian tube. Experimental study.

Experimental substitution of a long segment of ureter by a fallopian tube was performed in dogs. Three different techniques of proximal and distal anastomosis for reconstruction of the urinary tract were used in three groups of animals. Based on this, it is believed that the fallopian tube, as a pedicle graft, could serve in female dogs as the most approximate ideal substitute for ureter because of (a) anatomic proximity to the ureter permitting blood supply to the tube, (b) the fallopian tube's mucosa lining is not affected by urinary excretions, (c) does not allow absorption of electrocytes, (d) has a muscular wall with peristaltic activity, and (e) avoids the problems of antigenicity and/or foreign body reaction.

The parachute mitral valve complex. Case report and review of the literature.

A 10-month-old infant, the youngest patient thus far reported to have undergone successful correction of the developmental complex known as "parachute mitral valve," is presented. Severe mitral incompetence and aortic coarctation led to recurrent cardiac failure. Both anomalies were corrected in a one-stage procedure wherein the coarctation was resected under normothermia and the mitral valve replaced thereafter by a prosthesis employing deep hypothermia and total circulatory arrest. He made an uneventful recovery. Forty-two reported cases in the literature are reviewed and the pathologic and clinical features, diagnosis, natural history, and management briefly summarized.

Tracheobronchial resection and reconstruction. A report of five cases.

During the past six years, five patients have undergone tracheal or tracheobronchial reconstruction in our Department. In three patients, a segmental tracheal resection was performed because of post-tracheostomy stricture or cylindroma of the trachea. Two patients were treated for a carcinoid type of bronchial adenoma--one by sleeve resection of an intermediate bronchus and one by pneumonectomy with partial resection and reconstruction of part of the trachea. The exact location, length and nature of the lesions were demonstrated by endoscopy, tomography and tracheobronchography. The surgical and anesthetic problems associated with tracheobronchial reconstruction are discussed.

[A case of aorta-to-left ventricle tunnel accompanied by electrocardiographic modifications].

A new case of aorta-to-left ventricule tunnel is described in a young man of 20. The clinical picture was that of a typical and severe aortic incompetence combined with intermittent left bundle-branch block. During operation a typical aorta-to-left ventricle tunnel was found located above the right aorta Valsava sinus. The aortic valve was normal. The tunnel was closed at both extremities and extracorporeal circulation, which resulted in abolition of the aortic incompetence and disappearance of the left bundlebranch block. The literature at out disposal indicates that till now, thirteen other cases were described, since Morris Levy described the first in 1963. The anomaly might be corrected. On the fourteen cases, nine were operated upon, six of which successfully. We feel that the left bundle-branch block was probably caused by the mechanical trauma to the conduction pathway caused by the regurgitation, in view of the proximity between the left bundle-branch and the tunnel. Obliteration of the tunnel resulted in abolition of the traumatic effect and consequently disappearance of the left bundle-branch block.
