AV-fistill í nára

Abstract

Ágrip Hér er lýst tilfelli sjúklings sem greindist með fistilgang milli slag- og bláæðar í nára 8 árum eftir hjartaþræðingu. Greining var gerð á tölvusneiðmynd sem var hluti af uppvinnslu fyrir enduraðgerð með þræðingartækni (TAVI). The common femoral artery is a widely used for access in endovascular interventions. Various complications, such as hematoma, pseudoaneurysm and AV-fistula (AVF), can arise from arterial punctures with estimated prevalence between 1-10%. AVF is a rare complication with prevalence p<1%. AVF can cause a hemodynamic change in the form of a arteriovenous shunt (AV-shunt). AV-shunts in the groin are usually small and asymptomatic but tend to be symptomatic with larger and persistent AVFs which can present with leg claudication or high outpute heart failure.
