Cruciate Anastomosis
- Discussion:
- anastomoses between:
-
superior &
inferior gluteal arteries and
medial &
lateral circumflex;
-
deep circumflex artery & ascending lateral circumflex femoral
- these vessels provide collateral circulation when
femoral artery is occluded above origin of the
profunda femoris ;
- internal iliac & profunda femoris can be ligated w/ impunity;
- ligation of external iliac or femoral artery below exit of profunda femoris will restrict blood flow but is not accompanied by gangrene;
- ligation of the femoral artery above the exit of the
profunda femoris artery or in adductor canal, or common iliac artery is catatrophic;
- although there is copius
arterial communications about knee joint between branches of
femoral artery,
lateral femoral circumflex artery,
anterior tibial artery, &
popliteal artery, there is inadequate collateral circulation to supply leg w/ popliteal disruption;
- numerous anastomoses between anterior &
posterior tibial artery maintain viability when either is occluded;
