The influence of gender on the outcome of arterial procedures in the lower extremity


Enzler, M A; Ruoss, M; Seifert, Burkhardt; Berger, M (1996). The influence of gender on the outcome of arterial procedures in the lower extremity. European Journal of Vascular and Endovascular Surgery, 11(4):446-452.

Abstract

OBJECTIVES: To determine the outcome of arterial reconstructive procedures, we audited retrospectively peripheral bypass grafts and endarterectomies performed between 1982 and 1990.
MATERIALS AND METHODS: 1005 peripheral arterial procedures were performed in 862 lower limbs in 782 patients. 62% of the limbs were critically ischaemic. The procedures include 565 bypasses, 346 endarterectomies and 94 combinations of both. 30% of the patients were women. Follow-up information was obtained from practitioners in charge of post-hospital care by questionnaires. Factors potentially affecting patency were investigated by multivariate analysis and patency rates were calculated by life-tables.
MAIN RESULTS: Overall secondary patency was 61% at one year and 35% at 5 years. Bypasses and endarterectomies in women yielded lower patency rates than in men (49% vs. 67% at 1 year, p < 0.001). The relative risk of failure in women as compared to men was 1.30. The risk of failure was further increased by "redo" surgery (relative risk 1.51), diabetes (1.40), critical ischaemia (1.34) and crural procedures (1.34).
CONCLUSIONS: Secondary patency rates were significantly lower in women than in men. This is in agreement with some other studies, although gender has gained little attention as a risk factor in vascular surgery.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
