[Simultaneous carotid and coronary operations: experience and results of 11 years (1990-2000)].

Between 1990-2000 163 coronary + carotid procedures were performed. The mean age was 4 years higher than it was at patients underwent isolated CABG (63.4 y vs 59.8 y). Clinically proven obliterative artery diseases in other anatomical regions were also present in more than 60% of patients. The half of the procedures were performed under emergency and urgent circumstances. The cardiac status and the coronary morphology were found to be unstable in half of the patients. The "Euroscore" risk evaluation model was used for risk scoring. The mean score value was as high as 6.26. According to this the estimated surgical lethality could have been as high as 11.2%. The real surgical lethality value was far under this estimated level (7.36%). The 1, 5, 10 year survival rate were as high as 89%, 82%, 68% (Kaplan-Meier). The majority of the patients was in NYHA I-II at the end of the follow-up period. The majority of the early and late deaths were found to be myocardial in origin. The estimated surgical risk of the simultaneous procedures could be reduce by accepting of the severe surgical indications existing at this surgical field and with the availability of an experienced operating team.

[Late results after eversion endarterectomy of the internal carotid artery].

OBJECTIVES: The eversion endarterectomy of the internal carotid artery was introduced in Hungary in 1991. The aim of this study was to define the long-term restenosis rate of this new method. MATERIALS AND METHODS: Between 1991 and 1993, 171 operations were performed by one surgeon on 151 patients: 109 patients had enough compliance to take part in long-term follow-up, which included annual physical and ultrasound (Ultramark 9) investigations. Restenosis rate and plaque morphology was defined. Survival and patency rates were calculated by life-table method. RESULTS: The perioperative combined stroke morbidity and mortality rate was 0.8%. The 5-year patient survival rate was 85%, the recurrent stenosis free rate was 88%/5 years, and 9% of the patients had restenosis greater than 70% in this period. The plaque morphology showed calcification in 1 case. Two patients needed 3 reoperations (2.4%). Plaque histology showed myointimal hyperplasia in every 3 cases. CONCLUSIONS: Comparing our results to the literature (2-34% restenosis rate) it seems to be acceptable and encouraging for the future. The ultrasound and histological findings suggest that arteriosclerosis does not play significant role in development of restenosis after the eversion method.

[Importance of carotid artery studies prior to coronary surgery].

The incidence of cerebral complications following extracorporal cardiac operations is reported to be approximately 2%. One of the possible reasons behind these complications is the presence of significant carotid stenosis as coexistent disease to the cardiac illness requiring surgery. Because of the common etiology carotid stenosis coexists mainly with a coronary artery disease. The authors make known their own screening methods based on the correct exploration of medical history and on the proper physical examinations. Coexistent significant carotid stenosis was revealed in 3.6% of 1056 patients who underwent coronary surgery within the period of 41 months. In all of these cases prophylactic carotid endarterectomy was performed. In twenty cases within this group the carotid reconstructions were performed simultaneously with myocardium revascularization. Staged endprocedures were performed in the other 18 cases. There was no surgical mortality and only one patient suffered major stroke. The authors emphasize the importance of carotid screening among patients awaiting coronary surgery especially in patients who previously sustained cerebral ischemic attacks, the presence of carotid bruits or any other known localization of obliterate arterial disease and finally in all patients over 60 years of age.

[Late results of thoracic sympathectomy in various diseases].

The late results of 171 thoracal sympathectomies performed on 142 patients in the 20-year period 1952 to 1971 are described. Favourable results were achieved in Raynaud's disease, obliterating endarteritis and other occlusive vascular diseases, and also in hyperhidrosis.

Development and treatment of false aneurysm following vascular intervention.

The development and treatment of false aneurysm after cardiovascular intervention is discussed. At the Cardiovascular Surgical Clinic of Semmelweis Medical University (Budapest) 6900 reconstruction operations were performed. Ninety-five false aneurysms were operated on. According to the cause leading to the complication the patients are classified into 8 groups. To treat the false aneurysm 14 types of operation were carried out. Operative mortality was 12.6 per cent, but the outcome was successful in 70 per cent of the patients. The technique of surgical treatment is described. A review of the literature is presented.
