It is a quick, non-invasive way of confirming or excluding this pathology. The most common reason for referral for this procedure is to determine whether or not there is deep venous thrombosis (DVT or a clot) in one of the deep veins. Access may be compromised for those with more thrombogenic ports. A venous Doppler ultrasound scan serves to image the deep veins in the patient’s arm or leg. The former also had a higher frequency of access vein occlusive thrombus.Ĭonclusions: Thrombosis is concerning among patients with arm TIVADs, is often unrecognized, and warrants further investigation. Among those receiving an ultrasound, 15 cases of venous thrombosis were identified among those with the larger, power injectable, polyurethane catheter (n = 76, 19.7%) and 6 among those with the smaller, nonpower injectable, silicone catheter (n = 67, 9.0%, P = 0.08). Twenty-one of these 140 patients (15.0%) developed venous thrombosis, 2 symptomatic and 19 asymptomatic. Two ultrasounds were performed earlier than at 3 months to investigate clinically suspected venous thrombosis. There was no thrombus between these two points of insonation to explain this abnormality, so proximal pathology was suspected. Results: By 3 months postimplantation, 140 patients had undergone ultrasound. A and B, Pulsed-wave Doppler sonogram of left common femoral vein (A) shows normal to low-amplitude phasic waveform, and pulsed-wave Doppler sonogram of left femoral vein (B) shows flat waveform. A small probe is moved over the surface of the leg from. A Doppler ultrasound study may be part of a venous ultrasound examination. This test uses ultrasound (sound waves) to examine the veins in the patients legs.

Patients were scheduled to have an ipsilateral arm, subclavian region, and base of neck venous Doppler ultrasound 3 months after port implantation, or sooner, if clinically indicated. Venous ultrasound provides pictures of the veins throughout the body. Methods: Patients were randomized to receive 1 of 2 totally implanted venous access devices (TIVADs), either a nonpower injectable Cook TIVAD with a 5F catheter or a power injectable AngioDynamics TIVAD with a 6.6F catheter. Because the outcome of venous thrombus occurred more frequently in power injectable port recipients, this analysis further investigates thrombus characteristics by port type among patients who underwent Doppler ultrasound within 3 months of port implantation. A randomized cohort of 211 oncology patients receiving either a power injectable or nonpower injectable implanted arm port were prospectively assessed for complication-related removal.

Background: Venous thrombosis is a possible complication of vein port insertion.
