Abstract
A total of 38 patients 22 women and 16 men median age of 55 years were referred to our interventional unit for thrombosed implanted CVPs The period between CVP implantation and the initial suspicion of mechanical complication varied from 2 to 35 months mean 115 months and the interval since last use of the CVP averaged 47 days range 28–324 days Our mechanical thrombolysis technique was performed to fragment thrombus in the port chamber by whirling the floppy tip of 0018inch hairwire Only 19gauge noncoring needle and 0018inch hirewire were used without cutdown After removing the hairwire and placing a second needle the fragmented thrombi was slowly aspirated with a negative pressure and the remnant thrombus was flushed out by pushing a saline fluid The degree of fragmentation of thrombus was evaluated with posttreatment angiography incomplete lysis was defined as more than 50 of thrombus remaining significant lysis was 10–50 of initial thrombosis remaining and nearcomplete lysis was less than 10 thrombus remainingWe observed nearcomplete lysis in 22 patients 58 significant lysis in 14 patients 37 and incomplete lysis in two patients 5 The technical success rate was 82 31 of 38 patients There were no major or minor complications in the recovery room during a 30min observation period or late complications at outpatient followup
