Dear friend, welcome to HCM !
A blocked permacath needs to be removed and another placed if need continues.
Sometimes we may try intra catheter thrombolysis
with tPA/ STK. Success rates vary.
What was it inserted for? (underlying condition?)
is unrelated. Will need to be evaluated clinically and with an Xray chest.
A 2Decho can look into the heart chambers to see for clot propagation. is the cath in the neck or near collarbone?
Take care and please keep me informed of your progress.
Good Luck !
I hope to have answered your query satisfactorily.
