Preoperative smoking status was not observed to be associated with postoperative mortality , cardiovascular complications , bleedings , anastomotic leakage , or allograft rejection .
CONCLUSIONS Preoperative smoking was found to be associated with an increased risk of the following postoperative complications : general morbidity , wound complications , general infections , pulmonary complications , neurological complications , and admission to the intensive care unit
OBJECTIVE To systematic ally review and summarize the evidence of an association between preoperative smoking status and postoperative complications elaborated on complication type .
BACKGROUND The conclusions of studies examining the association between preoperative smoking and postoperative complications are inconsistent , thus there is a need for a review and meta- analysis to summarize the existing evidence .
Risk factors for complications after carotid endarterectomy--a population-based study.
OBJECTIVES The overall benefit of  carotid endarterectomy ( CEA )  is dependent on the outcome from the procedure . However , many reports are from selected centres and not population -based . The aim of this study was to assess the 30-day complication rate for a whole country and also to determine independent risk factors for serious complications . MATERIAL S AND METHODS One thous and five hundred and eighteen CEA were retrospectively review ed , covering principally all the CEAs in Sweden , during a three year period . Indications for surgery were ; minor stroke 34 % , TIA 34 % , amaurosis fugax 18 % , asymptomatic 11 % and others 3 % . Data were collected from the Swedish Vascular Registry ( Swedvasc ) . Combined cohort and case-control methodology was used . RESULTS Registered complications were ; 43 permanent strokes , 32 transient strokes ( < 30 days ) , 18 TIA/amaurosis fugax and 22 deaths ( seven fatal stokes ) . In the cohort study , the 30-day permanent stroke and death rate were 4.3 % ( 65/1518 ) . Significant risk factors in multivariate analyses were the indication for surgery ( minor stroke vs. other indications ) ( p=0.02 , RR=1.38 ) , diabetes ( p=0.02 , RR=1.41 ) , cardiac disease ( p<0.01 , RR 1.43 ) and operation at a university hospital ( p=0.02 , RR=1.39 ) . In the case-control study comparing the 65 cases of permanent stroke and /or death with 130 matched controls the only significant risk factor was contralateral occlusion ( p<0.01 , OR=5.27 ) . One patient ( 1/130 ) with a permanent stroke was wrongly reported as a local neurological complication ( facial paresis ) . CONCLUSION This national audit demonstrated population -based data on complication rates after CEA well comparable with previous r and omised trials . The validity of the Swedvasc data was confirmed . Combined cohort and case-control methodology was useful in analysing risk factors for serious perioperative complications
