[Noninvasive evaluation of cardiac index and ejection fraction in ischemic heart disease. Comparison of thoracic bioimpedance, thermodilution and cineventriculography].

Aim of the study was to verify the reliability of thoracic bioimpedance cardiography (TEB) in detection, non-invasively, cardiac index (IC) and ejection fraction (FE), compared to simultaneous evaluation by invasive thermodilution (TD) in 39 patients with acute myocardial infarction in Killip class I-II (group I), and by cineventriculography (CVG) in 26 patients with chronic coronary artery disease in NYHA class I-II (group II). In order to define the reproducibility of TEB values, in the latter patients, the above mentioned parameters were evaluated 6 times more, running the first evaluation. The statistical analysis was performed by the linear regression test and the Student's "t" test and by the test of variance for the reproducibility evaluation. Results (mean +/- SD) were as follows: group I: TEB-IC 2.89 +/- 0.63; TD-IC 2.83 +/- 0.56 (1/min/m2); r = 0.68; p < 0.01. Group II: TEB-IC 2.88 +/- 0.71; CVG-IC 3.48 +/- 0.66; r = 0.77; p < 0.001; TEB-FE 57.7 +/- 6.8%; CVG-FE 58.1 +/- 13.7%; r = 0.40; p = ns. Results of the reproducibility referred to the 6 measurements (mean +/- SD) were the follows: TEB-IC (1/min/m2) (1) 2.83 +/- 0.76; (2) 2.85 +/- 0.73; (3) 2.8 +/- 0.79; (4) 2.83 +/- 0.71; (5) 2.87 +/- 0.81; (6) 2.88 +/- 0.8, p = ns, the variability was assesses within +/- 9.3%. TEB-FE (%): (1) 56.7 +/- 6.2; (2) 55.8 +/- 5; (3) 57.1 +/- 5.5; (4) 56.1 +/- 6.1; (5) 55.4 +/- 5.8; (6) 57.3 +/- 6.3, p = ns; the variability was assessed within +/- 9.1%. The analysis of the results showed a good correlation in the IC detection among TEB and the compared techniques, conversely TEB evaluation of FE appear of poor values in this kind of patients. Relatively to the results of the reproducibility this unquestionable characteristic of TEB was demonstrated.

[Surgical treatment of diseases of the thoracic portion of the esophagus].

An analysis of 299 operations on the thoracic part of the esophagus has been made. The authors consider the method of choice to be a one-step operation of the Lewis type in cancer and scarry strictures of the esophagus. Clinical signs of diverticulitis even of a small degree are thought to be indication to diverticulectomy.

The Southern Thoracic Surgical Association 50th anniversary celebration: the impact of STSA pediatric cardiothoracic surgery manuscripts on surgical practice.

BACKGROUND: Members of the Southern Thoracic Surgical Association (STSA) have presented important pediatric cardiothoracic surgery papers at the annual meetings over the last 50 years. In order to determine the influence of these presentations on the practice of surgery, a review was undertaken. Early papers were characterized by emerging advances in open-heart surgery, anatomic congenital heart studies, and electrophysiologic discoveries that extended life with pacemakers. Later years were characterized by innovative myocardial preservation methods, improved cardiopulmonary bypass techniques, expanded homograft availability, emphasis on accurate repairs, intraoperative transesophageal echocardiography, and cardiopulmonary transplantation. METHODS: All but one of the scientific programs of the annual meetings (that of 1964) were located. The programs were reviewed and 180 presentations were identified on topics in congenital heart disease, pediatric thoracic disease, and pediatric thoracic wall abnormalities. Of those 180 oral presentations, 155 manuscripts (86%) were eventually published or in press and available for critical review and analysis. Manuscripts were grouped by diagnosis or therapeutic intervention. We determined a "cumulative citation frequency" (CCF), which measures the number of times an article is cited in the bibliography of related papers in the universe of participating journals. The selected manuscripts were compared with the historic landmark contributions and the existing trends at the time, and the number of articles both by individual authors and from institutions were tallied. RESULTS: Grouping by authors and institutions showed that 100 of 155 pediatric cardiothoracic manuscripts (65%) originated from 13 institutions. The CCF for the 20 leading articles ranged from 26 to 93. CONCLUSIONS: This historical STSA 50-year record of pediatric cardiothoracic advances was accomplished in a milieu of collegial respect and camaraderie. Our annual meetings over the years have provided a venue for thoracic surgeons to share their ideas, innovations, and scientific inquiry. These contributions have significantly affected the practice of pediatric cardiothoracic surgery. The STSA has worked for 50 years and we trust that it will work for another 50 years and beyond.

Thoracic manifestations of liver disease.

The close proximity of the liver to the right lung may be the basis for thoracic changes that occur in the presence of lung disease, or such changes may occur as part of the natural course of the disease. Whatever the etiology, the selective use of plain film radiography, fluoroscopy, radionuclide scanning, gallium scanning, and computed tomography will facilitate diagnosis and management.

Endovascular treatment of aortic dissections and thoracic aortic aneurysms.

Diseases of the thoracic aorta pose a significant challenge to the surgeon because of the complexity of the disease and the characteristics of the patient population. Frequent comorbidities and increasing age account for mortality rates between 5% and 20% for surgical repair of descending thoracic aortic aneurysms and in excess of 50% for Stanford type B aortic dissections, when complicated by preoperative end-organ ischemia. Endovascular techniques of fenestration, stenting, and stent-grafting have emerged as viable alternatives to conventional surgery in these patients. The authors review their experience using endovascular stent-grafts in the treatment of 103 patients with descending thoracic aortic aneurysms and 19 patients with acute aortic dissections. Fenestration and stenting are also addressed as adjuvant therapies in the treatment of complicated aortic dissections. Actuarial survival for aneurysms was 81% +/- 5% at 1 year and 73% +/- 5% at 2 years. Stent-grafting for acute aortic dissections achieved instant relief of symptoms in 71% of cases with an early procedural mortality of 16%, and endovascular revascularization of ischemic beds was achieved in 93% +/- 4% of cases of peripheral or visceral ischemia. The authors' experience supports the use of endovascular techniques in the treatment of thoracic aortic pathologic conditions. Longer follow-up and results of ongoing trials that use newer devices will help define the indications for their future use.

A case of neurofibromatosis with severe osseous disease of the thoracic spine.

A case of neurofibromatosis in a 7-year-old boy from Greenland is presented. The patient suddenly developed a severe thoracic scoliosis because of a total luxation of the upper thoracic vertebrae caused by erosion from soft tissue tumours in the region. Tomography revealed the bone changes, and CT whole-body scanning showed the extent of the soft tissue tumours and also the destruction of the vertebrae. The diagnosis was verified by biopsy.

Preoperative embolisation, transpedicular decompression and posterior stabilisation for metastatic disease of the thoracic spine causing paraplegia.

During a brief period from March 1988 to January 1990 we were faced with 13 patients with malignant vertebral neoplasms (metastasis) of the thoracic spine. Nine of these had progressive extradural spinal cord compression with motor, sensory and sphincter involvement of varying degrees and duration. After proper evaluation these 9 cases were aggressively managed by preoperative embolisation of the tumour, transpedicular decompression and a same stage posterior metallic fixation. The immediate results were encouraging, with 2 patients showing total recovery and 3 showing partial recovery. All of the 9 operated cases were pain free postoperatively and could sit up unaided and be easily transferred to the Cancer Institute for back up chemotherapy and radiotherapy. They also improved psychologically, and cooperated well in their subsequent rehabilitation programme.
