Fracture and intra-cardiac embolisation of a totally implantable vascular access device.
نویسندگان
چکیده
Totally implantable vascular access devices (TIVADs) provide a semi-permanent route for administering intravenous medication in patients who receive repeated courses. They are relatively easy to look after and cosmetically acceptable, but may be associated with complications [1] . A 17-year-old male with cystic fibrosis while undertaking a course of home antibiotics for a pulmonary exacerbation, through a left internal jugular TIVAD (3 years old), developed pain and tenderness around the TIVAD site. At review there was a small swelling above the left clavicle. The screening linogram ( fig. 1 ) revealed the catheter had fractured where it traversed the left clavicle and the distal portion projected over the heart and left lung base, suggesting fragment embolisation. At right heart catheterisation via the femoral vein (local anaesthetic and 2-mm percutaneous access), the fragment having migrated through the pulmonary valve was within the left lower-lobe pulmonary artery and was retrieved using a goose neck snare device. It seems likely that stretching forces applied to the catheter as the patient grew, plus friction where the catheter passed over the clavicle, caused the line to wear until it cracked. This is the first report of embolisation of a catheter fragment beyond the right ventricle in an adult with cystic fibrosis. Any unusual symptoms related to the device should prompt immediate discontinuation of use and urgent imaging by means of chest radiography and screening linography. Published online: April 20, 2012

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

Handling measures for the implantable vascular access device to prevent of catheter fracture/disruption
This study aims to investigate the causes of catheter fracture and handling measures for implantable vascular access devices to prevent catheter fracture. We retrospectively examined 3088 adult patients with catheter fracture/disruption caused by totally implantable vascular access devices (TIVDs). In the 3088 cases, implantation was via the internal jugular vein in 2909 cases and the subclavia...

Totally implantable venous devices (TIVDs) are now frequently used for the administration of chemotherapy, prolonged intravenous infusion and blood aspiration without repeated venosection in cancer patients. However, the placement of TIVDs using classical subclavian vein puncture method is associated with several complications, such as infection, thrombosis, superior vena cava syndrome, cardiac...
