Multi-Detector Computed Tomography Venography in the Assessment of Dysfunction of Tunneled Hemodialysis Central Vein Catheters

Abstract

MDCTV provided a new possible way to assess dysfunction of tunneled hemodialysis central venous catheters.

Dyslipidemia Is Associated With Tunneled‐Cuffed Catheter‐Related Central Venous Thrombosis in Hemodialysis Patients: A Retrospective, Multicenter Study

“…Other regular treatments included management of hypertension, injection of insulin and erythropoiesis stimulating factor, and iron supplementation. Patients with TCC received US and computer tomography angiography (CTA) examinations 6 months after catheterization (4).A total of 341 patients were reviewed, and 285 patients were enrolled in the final analysis. We excluded patients with chronic liver disease (n = 8), a history of venous thromboembolism (VTE) (n = 4), those using lipidlowering drugs or warfarin (n = 15), missing information (n = 29) on body mass index (BMI), lipid, smoking, and without US and CTA examinations.…”

Successful tunneled catheter placement in a hemodialysis patient with idiopathic multiple central venous stenoses

“…Vascular Doppler sonography is a noninvasive imaging test widely used for guidance of CVC placement. In spite of its clear display of cervical part of internal jugular veins, it is, however, not reliable in the observation of thoracic veins due to overlying bones and lungs . In recent years, CT and three‐dimensional vascular reconstruction have gained ground for the advantages of short scan time, less contrast injection, and freely rotation projection .…”

“…In spite of its clear display of cervical part of internal jugular veins, it is, however, not reliable in the observation of thoracic veins due to overlying bones and lungs. 11 In recent years, CT and three-dimensional vascular reconstruction have gained ground for the advantages of short scan time, less contrast injection, and freely rotation projection. 12,13 Findings of CT venography were shown to be correlated closely with those of digital subtraction angiography, especially for benign venous obstruction.…”

A Case Report of a Direct Catheterization of Tunneled Cuffed Catheter via Superior Vena Cava: A Choice after Vascular Access Exhaustion

“…When compared, duplex ultrasound is recommended as the initial screening tool but it has a lower sensitivity in asymptomatic thrombosis. MDCTV is a good choice with better sensitivity and it is a convenient method that can be used before the intervention operation [6]. Digital subtraction angiography is considered the reference gold standard [7] and the only reliable way to make or exclude the diagnosis, with the disadvantage of being invasive.…”
