After anterolateral thoracotomy, before incision closure, indwelling plastic catheters were inserted percutaneously under digital and/or visual control into the intercostal space of access and the two neighbouring ones. Initially, we injected 25 mg of bupivacaine through each catheter (to a total of 75 mg), and subsequently - on the patients demand - another 15 to 25 mg per catheter. To date, 25 patients received repetitive intercostal nerve blocks by this method (ICB-group). We compared their personal and perioperative data with those of another 30 patients, receiving opiates systemically after major thoracic surgery (SA-group). Multiple blood samples from the ICB-group were analyzed by gaschromatography for bupivacaine concentration-time-profiles. In 19 of 25 patients (76%) the bupivacaine-injections provided sufficient analgesia, 6 patients required additional analgesics. The duration of general anaesthesia (ICB: 174 min vs. SA: 136 min) and the operation time (ICB: 103 min vs. SA: 94 min) were not statistically different in both groups. The periods of intensive care therapy (ICB: 0.7 d vs. SA: 1.2 d), artificial respiration (ICB: 11.2 h vs. SA: 21.6 h) and hospital stay (ICB: 12.1 d vs. SA: 14.2 d) were shorter for the ICB-group. Atelectasis (ICB: 20% vs. SA: 37%) and pneumonia (ICB: 0 vs. SA: 13%) were observed less frequently than in the control group, whereas tachyarrhythmia occurred in 6 of 25 ICB-patients compared to 4 of 30 SA-patients. Nevertheless, none of these parameters reached statistical significance (p less than 0.05). Maximum bupivacaine levels of 0.65 +/- 0.21 micrograms/ml were found after 29 +/- 12 min of intercostal application.(ABSTRACT TRUNCATED AT 250 WORDS)

Between December, 1967 and August, 1988, 147 heart transplants (64 orthotopic, 68 heterotopic procedures; 15 heart-and-lung replacements) were performed on 128 patients. In the majority of the recipients, dilated cardiomyopathy or end-stage ischaemic heart disease was diagnosed. From 1985 to the present, 70 transplants (45 orthotopic, 11 heterotopic and 14 heart-lung) took place. Seventeen of these patients (mean age 46.6 years) suffered from end-stage disabling (NYHA IV) coronary artery disease; in each case the angiogram verified severe stenosis or occlusion of the three main coronary artery systems. Their histories revealed a total of 22 previous myocardial infarctions; 8 patients needed a total of 9 surgical revascularization procedures. The left ventricular ejection fraction (LVEF) ranged from 9% to 24% (mean 15.3%). Before transplantation three patients required intraaortic balloon pump (IABP) support. Fourteen of the 17 patients are at present still alive with post operative periods ranging from 8 weeks to 3.5 years (the actuarial 90-days and 1-year-survival rates being respectively 91.7% and 81.5%). Twelve of the patients are in NYHA class I; 2 are in class II. Three late deaths occurred: one from pneumocystic carinii/cytomegalovirus pneumonia, a second from atypical pneumonia and a third from chronic graft rejection. Radionuclide ventricular studies demonstrated postoperative left ventricular ejection fractions ranging from 54%-81% (mean 71%).(ABSTRACT TRUNCATED AT 250 WORDS)

Three patients underwent single left lung transplantation for end-stage pulmonary fibrosis between June and November 1987. Preoperatively all were housebound, receiving continuous, supplemental oxygen, and their pulmonary function had deteriorated despite corticosteroid and cyclophosphamide therapy. Pulmonary preservation was by means of pulmonary arterial perfusion with modified Euro-Collins solution, 60 ml/kg, at 4 degrees C with adjunctive iloprost (synthetic prostacyclin) infusion. The heart from each donor was used successfully for transplantation. Good early graft function enabled extubation 11, 46, and 96 hours after transplantation. An omental wrap was used around the bronchial anastomosis, and bronchial healing was satisfactory in all. All patients had episodes of pulmonary rejection diagnosed by a combination of symptoms, chest x-ray infiltrates, the exclusion of pneumonitis by bronchoalveolar lavage, and prompt response to "pulse" steroid therapy. Two of the three patients had three episodes of opportunistic pulmonary infections: Herpes simplex pneumonitis, Pneumocystis carinii infection, and Aspergillus pneumonitis. The three patients were discharged from the hospital after 5, 6, and 7 1/2 weeks, respectively. The first and third patients remain alive and well, living essentially normal lives 24 and 19 months after transplantation with no evidence of arterial desaturation on exercise testing while breathing room air. The second patient had symptoms of deteriorating lung function with a progressive decline in forced expiratory volume in 1 second, vital capacity, and diffusion capacity despite repeated "pulse" therapy with combinations of methylprednisolone, antithymocyte globulin, and OKT3 (Ortho Diagnostic Systems Inc., Raritan, N.J.). An open lung biopsy specimen showed obliterative bronchiolitis, and this patient underwent orthotopic lung retransplantation, on the right side. Despite excellent early graft function and early extubation, he died of uncontrolled rejection and general debility after 3 weeks. This early experience in our center with two of three patients surviving 19 to 24 months, respectively, confirms the restoration of good pulmonary function and near normal life-style in patients with end-stage pulmonary fibrosis after single lung transplantation, as first reported by the Toronto Lung Transplant Group. We have used an alternative method of lung preservation (cold crystalloid pulmonary perfusion as opposed to topical cooling, used by the Toronto group), which provided excellent pulmonary preservation up to and beyond 4 hours' storage.(ABSTRACT TRUNCATED AT 400 WORDS)

After heart-lung transplantation in primates, cardiopulmonary reflexes were tested and shown to be present. The Hering-Breuer and cough reflexes were tested, as well as responses to an inhaled respiratory stimulant, vasodilator, and an intravenous anticholinesterase and antimuscarinic agent. Recovery of these responses, except to the anticholinesterase agent, suggests that reinervation occurs in autotransplanted organs in primates. The Hering-Breuer reflex was present at 1.9 and 2.2 months after the operation in two animals subjected to autotransplantation. These cardiopulmonary reflex responses were also demonstrated in two allograft recipients studied at 15 and 16.9 months after the operation. Return of protective reflexes such as coughing may be an important mechanism to prevent aspiration pneumonitis and other complications in humans.

Long-term results are presented in 60 patients (4 to 50 years old) who underwent a diaphragmatic graft procedure for relief of cardiospasm (achalasia) from 1962 through 1987. The operative technique involves construction of a pedicle flap of diaphragm. The muscular defect on the lower segment of the esophagus and the transplanted diaphragmatic pedicle that is sutured to the defect must be the same size. Immediate operative results were good. Only one complication developed, a case of pneumonia that was cured. The patients were followed up from 11 months to 25 years. Two patients were lost to follow-up, 55 had excellent results, and three patients still had nausea and heartburn but were better than before the operation. This procedure has three advantages: (1) It prevents the development of fistulas and diverticula at the site of the esophageal muscular defect; (2) it effectively eliminates both restenosis resulting from scar tissue and reflux esophagitis; and (3) it allows the cardia to recover its normal function and the esophagus to return to normal size at the site of the operation.

Pulmonary aspergilloma and pleural aspergillosis are a potentially lifethreatening disease resulting from the colonization of lung or pleural cavities by the ubiquitous fungus Aspergillus fumigatus. Twenty four patients with pulmonary aspergilloma and five with pleural aspergillosis underwent major thoracic procedures at our hospital between 1976 and 1986. Fourteen of the patients had haemoptysis, in 9 it was recurrent, and in 5 life-threatening. Tuberculosis, pneumonia, and sarcoidosis were the most common preexisting lung lesions. Surgical procedures included 7 pleuropneumonectomies, 18 lobectomies and 4 wedge resections. The postoperative mortality rate was approximately 7% (2 pat.). Based on the pathological examination 4 patients had unexpectedly a bronchial carcinoma in addition to the aspergilloma. Bronchopleural fistula with persistent air space was a serious complication only for patients after pleuropneumonectomy. 23 patients including those with complex aspergilloma and pleural infection had no postoperative complications; in none of the 27 operative survivors were there any recurrent symptoms over a follow-up between one and ten years. Good-risk patients with documented aspergilloma, even asymptomatic, should be resected, because of the danger of exsanginating haemorrhage. For patients with pleural aspergillosis only the aggressive resection can provide effective long term palliation.

A case of thrombosed and infarcted left atrial appendage is presented. These findings occurred in a 28-day-old infant who died of pneumonia due to Hemophilus influenzae. Congenital abnormalities of the atrial appendages including hypoplasia, right and left isomerism and juxtapositions, and aneurysmal dilatations with and without pericardial defects are relatively uncommon. Acquired defects are also uncommon, and are often iatrogenic in nature. This report describes the case of a thrombosed and infarcted left atrial appendage in a 28-day-old infant.

Actinomycosis is an uncommon infection. The regions mostly involved are the cervico fascial area, the thorax and the abdomen. The thoracic variety accounts for approximately 15% of the cases. Clinical pictures of pulmonary neoplasm, abscess, and empyema have been described. Misleading symptoms often delay the right diagnosis. The present study describes a case of actinomycosis with pleuro-pulmonary involvement. A 48-year woman had been well until two and a half years previously, when she developed symptoms suggestive of pneumonia. When referred to a medical clinic with thoracic pain and tiredness, pulmonary embolism was suspected. Inhalation and perfusion scintigraphy showed several perfusion defects. There were several relapses, with clinical pictures suggestive of pulmonary embolism, before an abscess in the left axilla appeared. Drained pus showed no growth of Actinomycetes. Correct diagnosis of the true cause was only possible by direct microscopy. Possible symptoms and the diagnostic difficulties when Actinomycetes is involved are discussed.

One hundred eight-five patients with potentially operable lung cancer were prospectively evaluated by computed tomographic scanning of the mediastinum and upper part of the abdomen. Mediastinal lymph node size was correlated with operative and pathologic findings. There was close agreement between computed tomographic estimate of size and operative measurements. Mediastinal lymph nodes that were larger than 2.0 cm were positive for tumor in 69.6%, nodes between 1.1 and 1.9 cm contained metastases in 31.8%, and nodes less than 1.0 cm were positive in only 2.7%. The cell type, T status, and location of the primary tumor did not influence these findings: A node less than 1.0 cm with a T3 lesion had the same probability of being abnormal as with a T1 lesion, although predictably, those patients with T3 and central tumors had a greater likelihood of having nodes larger than 2.0 cm. The presence of pneumonitis did not increase the prevalence of enlarged, histologically normal nodes. Asymptomatic adrenal metastases were present in 3.2% of patients with otherwise operable disease and were suggested only by the computed tomographic scan. Patients with mediastinal nodes less than 1.0 cm probably do not need preresection mediastinal exploration. Those with nodes larger than 2.0 cm should not be considered unresectable without pathologic confirmation, even in large tumors, in view of the 30.4% negativity rate. The computed tomographic scan is useful in depicting and localizing enlarged mediastinal nodes but cannot be used as a substitute for pathologic examination.

Sixty-six children aged between 8 months and 15 years (average age 5.5 +/- 3.8 years) underwent mitral reconstructive operations for congenital mitral regurgitation between June 1969 and February 1987. The pathologic findings of the mitral valves were annular dilatation in 37 patients, cleft of the leaflet in eight, hypoplasia of the leaflet in 44, perforation of the leaflet in one, chordal elongation in 22, chordal absence in 16, and chordal shortening in seven. The methods of repair consisted of asymmetric annuloplasty (Kay-Reed method) in 61 patients, De Vega-type annuloplasty in one, plication of redundant leaflet in 15, and closure of cleft or perforation in nine. The single operative death (1.5%) was due to heart block. Follow-up data were available over 373.8 patient-years (average 5.7 years). The four late deaths (6.0%) were due to heart failure in two patients, pneumonia in one, and hepatitis in one. The actuarial survival rate was 93.1% +/- 3.1% at 7 years and 88.4% +/- 5.1% after 17 years. Valvuloplasty failed in 19 of the long-term survivors. One of these patients underwent mitral valve replacement 11 years after initial operation. The rate of freedom from reoperation was 86% +/- 10% after 17 years. The rate of freedom from valvuloplasty failure was 80% +/- 6.7% after 5 years, 67% +/- 7.2% after 10 years, and 44% +/- 11.9% after 15 years.
