Created page with "==Background== *AV fistulas/grafts can form a aneurysm or pseudoaneurysm which can lead to bleeding and other complications **Aneursym: contains all layers of the vessel wall..."

New page

==Background==
*AV fistulas/grafts can form a aneurysm or pseudoaneurysm which can lead to bleeding and other complications
**Aneursym: contains all layers of the vessel wall
***Most are asymptomatic; rarely rupture
***More likely in fistula than grafts
**Pseudoaneurysm: focal disruption of vessel wall with a collection of blood that is contained
***Results from subcutaneous extravasation of blood from puncture sites
***More likely in grafts than fistulas

==Clinical Features==
*Pts will have physical findings of a dilated aneurysm
*Bleeding
*Eschar
*Mostly asymptomatic

==Management==
*Depends if pt is symptomatic

*If these occur, pt will need emergent vascular consult:
**Eschar formation that does not heal
**Spontaneous bleeding from access sites
**Rapid expansion in pseudoaneurysm size
**Exposed graft

*AV Fistula: indications for vascular evaluation
**The skin overlying the fistula is compromised
**There is a risk of fistula rupture
**Available puncture sites are limited

*AV Graft: indications for vascular evaluation
**Pseudoaneurysm that is symptomatic
**Pseudoaneurysm that is twice the diameter of the graft (ie, >4 cm in diameter)
**Pseudoaneurysm that threatens the viability of the overlying skin, regardless of diameter
**Pseudoaneurysm that is expanding
**Large or multiple pseudoaneurysms that limit the number of cannulation sites.

==Disposition==
*Likely discharge home with vascular consultation
