The study sample collected between 2003-2009 consist of symptomatic carotid atherosclerotic plaques obtained from carotid endarterectomies performed at the Sahlgrenska University Hospital (Göteborg, Sweden). Criteria qualifying for surgery were minor ischemic stroke, transient ischemic attack (TIA) or amaurosis fugax and a high-grade carotid stenosis (≧70% determined with the European Carotid Surgery Trial method).

In 2010 the Collection of data was restarted with emphasis on collecting complete time series of endareterctomies. A further expansion led to inclusion of serum and plasma samples taken from patients with newly diagnosed abdominal aortic aneurysms (AAA). The latter Collection is also reffered to as the G3A study (Gothenburg Abdominal Aortic Aneurysm study) and led by Dr Marcus Langensköld.

Datasets from papers published in open access is made available on request.

Purpose:

A biobank of human atherosclerotic tissue harvested at carotid endarerectomy.</abstract>
      <abstract xml:lang="sv" contentType="abstract">Studiepopulation och undersökningar:

Studiens datainsamling genomfördes mellan 2003-2009. Data består av plack från halsartären som erhållits från karotis-kirurgi, utförd vid Sahlgrenska Universitetssjukhuset (Göteborg, Sverige). Kriterier som ledde till operation var mindre ischemisk stroke, transitorisk ischemisk attack (TIA) eller amaurosis fugax och en höggradig karotisstenos (≧ 70 % mätt enligt metoden ”European Carotid Surgery Trial”, ECST). Under 2010 påbörjades insamling av data på nytt, i syfte att samla in komplett tidsserie av plack från halsartären. 

En ytterligare expansion har lett till införandet av serum- och plasmaprover som tas från patienter med nydiagnostiserade bukaortaaneurysm (AAA). Den sistnämnda insamlingen anges även som studien G3A (Göteborg bukaortaaneurysm studien) och leds av doktor Marcus Langensköld.

Dataset från artiklar publicerade i open access kan förmedlas vid förfrågan.

Syfte:

En biobank med aterosklerotisk vävnad från människor, erhållen från karotis-kirurgi.</abstract>
