IfIweretoclampthefemoralvein…Femoralvenousouhlowwouldstop.

Distalvenouschannelsandcapillarybedswoulddilateanddistend.

Thefemoralarterywouldkeeppumpingbloodintotheextremity.

Soon(5-10seconds),thelimitoftheouterfascialcompartmentswouldbereachedandthelimbwouldbecomecongestedandswollen.

Arterialinflowwouldslowandeventuallystop.

Now,ifIremovedtheclamp…

•  Thefemoralveinwouldrapidlyempty,returningbloodtotheheartandcollapsingthevenous/capillaryvessels.

•  Arterialinflowtotheextremitywouldresume.

•  Theextremitywouldremainmaximallyvasodilated.
