[Comparative value of B-type natriuretic peptide and serum albumin concentration in the prediction of in-hospital mortality in elderly patients admitted for acute severe heart failure]. / Valeur prédictive comparée de mortalité hospitalière du peptide natriurétique de type B et de l'albuminémie chez le sujet âgé hospitalisé pour insuffisance cardiaque aiguë sévère.

OBJECTIVE: To address the clinical relevance of serum albumin and B-type natriuretic peptide (BNP) concentration in the prediction of in-hospital death in elderly patients with acute severe heart failure. PATIENTS AND METHODS: Seventy-four consecutive patients >70 years of age admitted for acute heart failure in NYHA class IV were prospectively included. BNP concentration was measured on admission and serum albumin concentration after clinical stabilization. RESULTS: Mean age was 86.6+/-5.7 years. Sixty-five percent of patients had a normal left ventricular ejection fraction. Eighteen patients died during the in-hospital stay. Those patients who died were older, had higher blood urea nitrogen and BNP concentration, had lower systolic blood pressure and serum albumin concentration than patients who survived. Heart rate, rhythm, left ventricular ejection fraction, serum creatinine and hemoglobin did not differ according to outcome. By multivariate analysis, albumin (p=0.0017), BNP (p=0.016) and age (p=0.03) were independent predictors of in-hospital death. Serum troponin I measured on admission in 71 patients was predictive of in-hospital death (p=0.01), as well as serum total cholesterol measured after stabilization in 66 patients (p=0.004). However, these two variables no longer predicted outcome in multivariate models, unlike serum albumin and BNP. CONCLUSION: Serum albumin and BNP offer independent, additional information for the prediction of in-hospital death in elderly patient with acute severe heart failure regardless of left ventricular ejection fraction.

[Precipitating factors associated with diastolic heart failure in the elderly]. / Facteurs aggravants associés à l'insuffisance cardiaque à fonction systolique conservée chez le sujet âgé.

BACKGROUND: Beside basal myocardial dysfunction, acute heart failure involves associated factors, which increase pulmonary capillary pressure or decrease colloid osmotic pressure. The aim of this study was to evaluate the prevalence of these precipitating factors in a population presenting with acute heart failure with preserved left ventricular systolic function. METHODS: Forty-eight patients (25 men, 78 +/- 10 years) presenting pulmonary edema with a left ventricular ejection fraction > 45% were included. All had a Doppler echocardiography at the time of intravenous loop diuretics initiation. Patients with severe valve disease or symptomatic coronary disease were excluded. RESULTS: A history of heart failure, coronary disease, hypertension and diabetes was present in 62%, 42%, 64% and 33% of patients, respectively. On admission, mean left ventricular ejection fraction was 61 +/- 9% and 79% of patients had critical elevation in Doppler filling pressures. Associated factors were renal failure (creatinine clearance < 30 ml/min) in 33% patients, silent myocardial ischemia (troponin I > 0.5 ng/ml) in 31%, atrial fibrillation in 29%, high systolic blood pressure (> or = 160 mmHg) in 27%, major sepsis in 25%, severe hypoalbuminemia (< or = 2.5 g/dl) in 23%, and severe anemia (< 10 g/dl) in 17%, respectively. Four patients had no aggravating factor, whereas 34 and 10 patients had 1-2 and 3-4 associated factors, respectively. CONCLUSION: Besides diastolic dysfunction, factors leading to a critical decrease in the oncotic pressure such as pulmonary capillary pressure gradient are found in most of the elderly patients presenting acute diastolic heart failure and must be checked systematically.

[Usefulness of Doppler echocardiography in the diagnosis of acute diastolic heart failure in the elderly]. / Apport de l'échocardiographie Doppler dans le diagnostic de l'insuffisance cardiaque aiguë à fonction systolique conservée du sujet âgé.

PURPOSE: To evaluate the clinical usefulness of the determination of Doppler mitral inflow pattern and new combined indices using colour M mode velocity flow propagation (Vp) in the diagnosis of acute diastolic heart failure in the elderly. METHODS: Total serum protein concentration (P, g/l) and E/A, E/Vp and 1000/(2 x IRT + Vp) Doppler indices (E and A: mitral inflow peak velocities; IRT: isovolumic relaxation time) were measured at the time of therapy initiation in 94 patients with left ventricular ejection fraction > 50% (78 +/- 13 years), 56 with pulmonary edema and 38 patients with acute respiratory disease. RESULTS: The feasibility was 73, 90 and 89% for E/A, E/Vp and 1000/(2 x IRT + Vp) respectively. The sensitivity, specificity and accuracy were 94-56-72%, 84-86-85% and 92-86-89% for E/A > or = 1, E/Vp > or = 2 and 1000/(2 x IRT + Vp) > or = 6 respectively in the diagnosis of pulmonary edema in patients with normal serum colloid osmotic pressure defined by P > or = 60 g/l, and 41-50-43%, 37-86-50% and 22-100-42% in patients with low colloid osmotic pressure (P < 60 g/l). CONCLUSIONS: The mitral inflow measurement is limited in most of cases of acute diastolic heart failure in the elderly by confounding factors such as atrial fibrillation and normalised pattern. New combined Doppler indices are useful in these patients, however, their value must be interpreted according to the serum colloid osmotic status estimated by total serum protein concentration.

Mediastinoscopy and permanent venous access device positioning through the same incision.

We report herein our technique for positioning of permanent venous access device in patients undergoing mediastinoscopy for diagnosis and/or staging of thoracic malignancies. Through the same 3-cm skin incision employed for mediastinoscopy, access to right internal jugular vein is obtained and the prepectoral pocket for chamber positioning is prepared. The technique is simple, safe and provides increased patient acceptability.

Aspergilloma: a series of 89 surgical cases.

BACKGROUND: Surgery for pleuropulmonary aspergilloma is reputed to be risky. We reviewed our results, focusing attention on the postoperative complications. METHODS: During a 20-year period, 87 patients were operated on for pulmonary (86) or pleural (3) aspergillomas. Seventy-two percent of patients were complaining of hemoptysis. Eighty-nine resections were performed because there were two bilateral cases. Seventy percent of aspergillomas had developed in cavitation sequelaes from tuberculosis disease. Thirty-four patients had severe respiratory insufficiency that allowed us to perform only lobectomy (18), segmentectomy (2), or cavernostomy (14). RESULTS: Thirty-seven lobectomies (five with associated segmentectomies), two bilobectomies, 21 segmentectomies, 10 pneumonectomies, and 17 cavernostomies were performed. Total blood loss exceeded 1,500 mL in 14 cases, and 71% of patients required blood transfusion. There were five postoperative deaths (5.7%), related to respiratory failure (2), infectious complication (1), pulmonary embolus (1), and cardiorythmic disorder (1). Incomplete reexpansions were frequently seen in patients undergoing lobectomies or segmentectomies. No death or major complications occurred in asymptomatic patients. During follow-up, none of the patients had recurrent hemoptysis. CONCLUSIONS: Surgical resection of aspergilloma is effective in preventing recurrence of hemoptysis. It has low risk in asymptomatic patients and in the absence of underlying pulmonary disease. Incomplete reexpansion is frequent after lobectomy and segmentectomy, especially when there is underlying lung disease. Cavernostomy is an effective treatment in high-risk patients. Long-term prognosis is mainly dependent on the general condition of patients.

Extended resections for bronchogenic carcinoma invading the superior vena cava system.

BACKGROUND: Extended resection of non-small-cell lung cancer (NSCLC) involving the superior vena cava (SVC) system is infrequently performed and oncologic benefits are still uncertain. METHODS: From 1983 to 1996, 25 patients underwent resection of the SVC system for T4, NSCLC. RESULTS: A total of 12 pneumonectomies (48%), ten lobectomies (40%), and three wedge resections (12%) were performed. Seven patients had complete resection of the SVC with graft interposition, 12 patients underwent tangential resection of the SVC, and 1 patient had a pericardial patch; 5 patients underwent resection of right innominate and subclavian veins without vessel reconstruction. The lymph node status was N0 in 8 patients (32%), N1 in 3 (12%) and N2 in 14 patients (56%). Five patients (20%) underwent incomplete resection. Nine patients (36%) developed postoperative complications (36%) that were fatal in 3 patients (12%). At the completion of the study, 10 patients were still alive. The median survival was 11.5 months and the 5-year actuarial survival rate was 29%, with 4 patients alive at 5 years. CONCLUSIONS: The resection of the SVC system for direct involvement by T4, NSCLC can be performed in selected patients with an acceptable postoperative mortality. Even though no significant prognostic factors were observed, the patients who required a lobectomy with limited lymph node involvement seemed to benefit the most from surgery.

Survival and prognostic factors in patients undergoing parenchymal saving bronchoplastic operation for primary lung cancer: a series of 110 consecutive cases.

OBJECTIVE: The purpose of this study was to report our experience concerning bronchial sleeve lobectomy for treating bronchogenic cancer. METHOD: From 1980 to 1994, 110 patients underwent bronchial sleeve lobectomy for bronchogenic cancer. In 45 patients, preoperative investigations contraindicated pneumonectomy, whereas in 65 other patients, sleeve resection was performed without functional necessity. The most common procedures were sleeve lobectomy of the right upper lobe (64%), and of the left upper lobe (21%). Sixteen patients (15%) underwent additional arterial vascular resection. Seven patients had microscopic invasion of the bronchial margin without the possibility of further resection in six with regard to their limited respiratory function. Tumors were staged as follow: 32 stage IB (all T2 N0), 57 stage IIB (57T2 N1), and 17 stage IIIA (eight, T3N1; nine, T2N2), whereas four patients had an in situ cancer (four stage 0). RESULTS: Operative mortality was 2.75%. The 5- and 10-year actuarial survival rates were, respectively, 39 and 22% for the entire group. The 5-year actuarial survival rates were, 60% in stage IB, 30% in stage IIB, and 27% in stage IIIA. Four factors significantly influenced survival (P<0.05): nodal stage, arterial resection, invasion of the bronchial stump and poor functional respiratory status contraindicating pneumonectomy. CONCLUSIONS: In our experience, sleeve resection for stage I provides comparable survival to that of standard resection at equal stage. However, in patients with pathologically N1 disease, who can tolerate a pneumonectomy, a randomized study is mandatory to confirm that sleeve lobectomy can be performed without the risk of decreasing long-term survival. In our study, patients who required an associated vascular resection demonstrated a poor survival.

Completion pneumonectomy: experience in eighty patients.

OBJECTIVE: Because completion pneumonectomy is a procedure reputed to place patients at risk, we reviewed our results with the objective of identifying factors that influence complications and survival. METHODS: In a 25-year period, 80 completion pneumonectomies were performed after first operations for 17 cases of benign disease and 63 cases of lung cancer (89% stages I and II), with 7 of the latter patients receiving postoperative radiotherapy. Completion pneumonectomy was performed in 18 cases of benign disease and 62 cases of lung cancer: 28 second primary cancers, 26 recurrent cancers, 3 metastases, and 5 primary cancers in patients previously operated on for benign disease. RESULTS: No intraoperative deaths occurred. Postoperative mortality rates were 5% for the entire series, 6.4% for patients operated on for cancer, and 0% for patients operated on for benign diseases. Patients previously irradiated and those operated on for infectious disease were at risk for postoperative empyema and fistula formation. In the cancer treatment group the actuarial 5-year survival was 36%, without significant difference between patients with recurrent and second primary lung cancers. The actuarial 5-year survivals were 51% for patients with stage I disease, 42% for patients with stage II disease, and 18% for patients with stage IIIA disease (P <.05). CONCLUSIONS: Completion pneumonectomy can be performed with an acceptable operative mortality rate and offers a second chance for cure to patients with cancer. Patients previously irradiated and those requiring completion pneumonectomy for infectious benign disease are at risk for postoperative complications.

Associated primary esophageal and lung carcinoma: a study of 39 patients.

From 1979 to 1992, of 1,294 patients with esophageal squamous cell carcinoma, 39 patients (3.2%) (38 male patients, 1 female patient; mean age, 58 years) had associated primary lung carcinoma. Criteria for the diagnosis of primary lung carcinoma were: (1) non-squamous cell carcinoma tumors, (2) tumors existing before the esophageal squamous cell carcinoma, and (3) solitary squamous cell carcinoma presenting with endobronchial involvement. The two tumors were observed synchronously in 22 patients (56%) and metachronously in 17, with a mean tumor-free interval of 46 months (range, 18 to 77 months). In patients with synchronous disease, 10 underwent nonoperative treatment or a palliative surgical procedure, and 12 (55%) underwent a curative operation. In patients with metachronous disease, a curative operation was performed in all for the first tumor and in 9 (53%) for the second tumor. The overall postoperative mortality rate was 15%. Two patients (10%) died after the curative operation. None of the patients died who underwent curative esophagectomy combined with lobectomy. For the patients with synchronous disease, the 5-year survival rate was 11% in those who underwent a curative operation, and the longest survival in those who received palliative treatment was 18 months. For the patients with metachronous disease, the 5-year survival rates from the date of the diagnosis of the second tumor were 17% for those who had a curative operation and 11% for those who received palliative treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Lung resection after high doses of mediastinal radiotherapy (sixty grays or more). Reinforcement of bronchial healing with thoracic muscle flaps in nine cases.

Mediastinal radiotherapy of more than 60 Gy highly compromises bronchial and wound healing after lung resection. Nine patients with primary lung cancers underwent radical resection after high radiation doses. Eight patients had primary lung cancer previously treated by radiotherapy alone (n = 2) or associated with chemotherapy (n = 6). One patient had a tracheal cancer involving the carina that was previously treated by radiotherapy. Seven patients underwent pneumonectomy and one patient underwent lobectomy with reinforcement of bronchial stump closure with use of the serratus anterior muscle. One patient underwent a sleeve lobectomy with bronchial reconstruction wrapped with an intercostal pedicle flap. Five patients had no postoperative complications and four patients had empyema, one associated with a small bronchial fistula. All except one patient were successfully treated by thoracostomy and immediate or secondary transposition of the pectoralis major muscle and the omentum to fill the cavity. These results show that lung resections can be done after high doses of radiotherapy without a high rate of bronchial fistula by using thoracic muscle flaps to reinforce bronchial stumps and anastomoses. In this procedure, surgical dissection is more time-consuming and increases the postoperative empyema rate (4/9). However, the higher long-term survival may justify this choice in selected cases.

[Hartmann's procedure. A retrospective study of 86 cases]. / L'intervention de Hartmann. Etude rétrospective de quatre-vingt-six cas.

The purpose of this retrospective study is to define current indications and results of Hartmann's procedure (H). From 1978 to 1989, 86 H were performed, 52 (60%) as emergency surgery. Indications were: colo-rectal cancer (37): 15 complicated and 22 as an elective procedure, diverticular disease acute or complicated (24), ischemic colitis (10), volvulus of the pelvic colon (5), inflammatory bowel disease (4), colonic perforation (3), traumatic hematoma of the sigmoid mesocolon (1). Fourteen patients died after operation (mean age: 79). There was no death after elective H for cancer. Post-operative complications were numerous: pulmonary (25%), abdominal would sepsis or disruption (21%), rectal strump leakage (14%), the later being harmless due to the associated Mickulicz drainage. Seven patients were reoperated on for necrosis of the colonic stoma. Mean initial hospital stay was 31 days. Restoration of the gastrointestinal continuity was done in 27 cases (37% of the surviving patients, 76% of the diverticular diseases). The authors conclude that for complicated diverticular disease H procedure improves survival without preferable continuity. For cancer, H procedure is permanently compromising gastrointestinal in the elderly to hazardous low anastomosis, and to palliative abdomino-perineal resection.
