Methods: Eight patients, two female (68 +/- 5 y), six male (73 +/- 4 y), were retrospectively evaluated. Patients showed neurological signs as followed: recurring attacks of vertigo (80%), temporary paresis of extremity (20%), speech disorders (20%) and subclavian and/or carotic-steel-syndrome (15%). Seven patients have already been previously treated with revascularization of the supraaortic branches in the past. The surgical techniques used were thrombendarterectomy of the internal carotid artery, carotid-subclavian bypass and complex aortotruncal, aorto-carotid and aorto-subclavian-bypass. Results: One patient died nine days postoperatively due to myocardial infarction. Mean duration of stay on intensive care unit was 1.5 days. Mean duration of postoperative ventilation was six hours. Average duration of stay on normal ward was nine days. Conclusion: This study presents several complex reconstructions of supraaortic branches, which were indicated in cases with severe stenoses of supraaortic branches. Even though treatment strategies were complex the peri- and postoperative complication rates are quite low. These therapeutic strategies were necessary to avoid severe neurological complications in these patients."],["dc.identifier.doi","10.5761/atcs.oa.09.01432"],["dc.identifier.isi","000294510200005"],["dc.identifier.pmid","21881320"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/22408"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Medical Tribune Inc"],["dc.relation.issn","1341-1098"],["dc.title","Complex Reconstruction of Supraaortic Branches"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Hemolysis and platelet dysfunction due to turbulence in the blood suction system strongly impede later usage of suction blood for re-transfusion. The aim of this study was to analyze the effects of a novel surgical-blood suction system with an automatic control setup for minimization of turbulence in the blood flow. Methods: We compared the turbulence-controlled suction system (TCSS) with a conventional suction system and untreated control blood in vitro. Blood cell counts, hemolysis levels according to free hemoglobin (fHb) and platelet function were analyzed to determine the integrity of the suction blood. Results: In the conventional suction system, we found a strong increase of the fHb levels. In contrast, erythrocyte integrity was almost completely preserved when using the TCSS. We obtained similar results regarding platelet function. The expression of platelet glycoproteins, such as GP IIb/IIIa and P-selectin, native or after stimulation with ADP, were markedly impaired by the conventional system, but not by the TCSS. In addition, platelet aggregometry revealed significant platelet dysfunction in conventional suction blood, but less aggregation impairments were present in blood samples from the TCSS. Conclusion: Our findings on an in vitro assessment show major improvements in red blood cell integrity and platelet function of suction blood when using the TCSS compared to a conventional suction system. These results reflect a significant benefit for autologous re-transfusion. We suggest testing the TCSS in surgery for clinical evaluation."],["dc.identifier.doi","10.1177/0267659118790915"],["dc.identifier.eissn","1477-111X"],["dc.identifier.issn","0267-6591"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/77305"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.publisher","SAGE Publications"],["dc.relation.eissn","1477-111X"],["dc.relation.issn","0267-6591"],["dc.title","The effect of a novel turbulence-controlled suction system in the prevention of hemolysis and platelet dysfunction in autologous surgery blood"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
