No full textIl Bypass aortocoronarico nella donna. risultati immediati ed a distanza
No full textThe present report summarizes the early and late results obtained in a series of 43 female patients, who underwent coronary bypass surgery during a 2-year period ending December 1983. This group constituted 11,2% of the total experience in that period. The mortality rate was 6,97% and incidence of perioperative myocardial infarction was 4,6%. At late follow-up (23,35 +o- 5,9 mounths) the 85% of patients resulted asymptomatic. Comparing these women with 43 men of the same age, angina subset and number of deseased vessels the operative risk resulted higher in the women. These findings may be explained on the basis of women having smaller coronary arteries and move severe variant of systemic atherogenesis than men
Ascending aortic dissection as sudden or late complication of cardiac surgery
No full textFrom January 1987 to December 1991 at Cardiac Surgery Center of Parma were performed 2019 operations under cardiopulmonary bypass (CPB). Ascending aortic dissection occurred as intraoperative complication in 7 (0.34%) patients (group A), and postoperatively in 3 (group B). In this series there were two deaths: one patient of Group A died intraoperatively, the second (group B) suddenly at five days after operation and the diagnosis was possible only on autopsy. The most cases had aortic valvular disease (7/10), with concomitant wall disease predisposing to dissection by surgical manipulations. Surgical techniques depend on the extent of the dissection; furthermore we prefer to repair the lesion under CPB. We believe that successful surgical treatment of the intraoperative dissection is dependent on early recognition
Carotid endarterectomy under hypothermic extracorporeal circulation: A method of brain protection for special patients
No full textThis study was undertaken to evaluate the efficacy of hypothermic extracorporeal circulation for cerebral protection in 17 patients having simultaneous carotid endarterectomy and cardiac operations. The cardiopulmonary by-pass (CPB) was conducted using total hemodilution. The body temperature was cooled to 25°C and the heart was arrested with cardioplegic solution. The carotid endarterectomy was performed first followed by the cardiac operation. No neurological or cardiac complications occurred. These results support the reliability of hypothermic cardiopulmonary bypass as a method of providing cerebral protection during simultaneous cardiac and carotid surgical procedures
Sostituzione valvolare mitro-aortica:fattori che influenzano il rischio operatorio.
No full text83 patients, 41 male and 42 female, mean age 54,04, operated on of mitro-aortic valve replacement from Jan 1982 to December 1987 were examinated to identify statistically significative operative risk factors. The vast majority of patients had calcific involvement of one (11,4%) or two (48,2%) valves; 7 cases underwent myocardial revascularization for concomitant coronary artery lesions and 17 (20,4%) had previously undergone cardiac operations. The hospital mortality was 8,4%, resulting significantly (p<0.05) influenced by more severe functional class of New Your Heart Association (NYHA) and by involvement of respiratory, renal and hepatic function; incremental risk factors for early mortality
Unilateral pulmonary embolectomy without extracorporeal circulation. A report of a clinical case
No full textThe surgical treatment of pulmonary embolectomy is currently indicated for acute massive obstruction of the pulmonary artery with severe haemodynamic failure and, as in this case, when medical treatment with anticoagulants or thrombolytic drugs is contraindicated. In this work, the Authors focus on the technique of unilateral pulmonary embolectomy through a median sternotomy; this approach allowed an easier and safer embolectomy without extracorporeal circulation
Asymptomatic patient reoperated on for severe proximal stenosis of circular sequential vein graft.
No full textThe case is described of a fifty year old man who underwent coronary bypass surgery using the circular sequential vein graft technique. At follow-up study (6 months after operation), despite his asymptomatic status, the effort test revealed antero-lateral myocardial ischemia. A coronary angiography showed a 90% proximal stenosis of the graft at 1.5 cm from the aortic anastomosis. The patient was reoperated on and the circular graft was reconstructed. Despite the severe stenosis this technique of myocardial revascularization has developed intercoronary anastomoses, improving the cardiac contractility and avoiding further clinical complications
Bypass aorto coronarico circolare: risultati immediati ed a distanza.
No full textAt Cardiovascular surgery department of Parma, from January 1984 through December 1985, myocardial revascularization with aortocoronary circular sequential vein graft technique was performed in 48 patients with severe and diffuse coronary stenosis and with saphenous vein with large caliber. There were no operative deaths, bypass/patient ratio was 5:1 and 6 patients underwent combined cardiovascular surgical procedures. The incidence of perioperative myocardial infarction was 4,1%. At mean follow-up interval of 37,35 mounths (ranging from 21 to 46) survival rate was 93,8% (1 non cardiac death occurring) and 4 patients (8,8%) had anginal recurrence medically treated. We concluded that in patients with clinical and perioperative features such as large saphenous vein, multiple distal coronary lesions, the aortocoronary circular bypass technique is indicated; moreover, because of its dependency on single proximal aortic connection this procedure should not been considered as an alternative method of myocardial revascularization, but can be used in selected coronarographic and intraoperative cases
Right atrial hemangioma
No full textA case of right atrial hemangioma as a rare tumor of the heart is reported. Because of its single, pedunculated mass, surgical excision of the tumor resulted in the complete treatment. Histologically, it was classified as arteriolar type. The importance of recent non-invasive techniques to diagnose these tumors during life is emphasized
Early and long-term results of coronary artery bypass grafting in patients with poor left ventricular function.
No full textThe case is described of a fifty year old man who underwent coronary bypass surgery using the circular sequential vein graft technique.
