Central venous access devices are routinely used in oncology for delivering chemotherapy of which implantable chemoports are the most common. Spontaneous breakage and migration of the catheters is a very rare but known complication of the procedure. Patients will usually present with cardiac manifestations in form of chest pain or arrythmias. Herein we report a case of spontaneous breakage and cardiac migration in which the patient was asymptomatic. Patient was successfully managed by an interventional cardiologist.Keywords Chemoport . Fracture . Migration A 3 year old male child was diagnosed as having Hodgkins lymphoma and subsequently planned for chemotherapy in our hospital. A chemoport catheter (bard, 6.6f) was placed in the right internal jugular vein and port was placed in the chest wall for chemotherapy. After the procedure, a chest x ray revealed good placement of the chemoport. Then the child underwent 6 cycles of chemotherapy in next 6 months through this port and had a very good response. Patient was then planned for port removal. On examination it was found that the port was in situ but the catheter was not palpable in the subcutaneous tissue of the neck. A chest radiograph was performed due to suspicion of catheter migration secondary to spontaneous breakage (dislodgement) of chemoport catheter. It showed that the chemoport catheter had migrated from its original location up to the right ventricle, travelling across the right atrium and right ventricle through pulmonary artery. (Fig. 1). Surprisingly the child was asymptomatic and there were no ECG changes as well. Patient was then referred to a cardiology department for a possible percutaneous retrieval of the migrated catheter. As the patient was asymptomatic and stable so an elective procedure was planned. On the next day patient was taken to cath lab and retrieval was done under fluoroscopic guidance under general anesthesia. The right femoral vein was punctured, and a 6Fr sheath was inserted. Percutaneous retrieval of migrated catheter was performed with a 6 Fr snare (peripheral snare, Cordis) (Fig. 2). Floating end of the migrated catheter in right atrium was snared and pulled down via inferior vena cava towards right femoral vein under fluoroscopic guidance and finally the port catheter fragment along with retrieval set were removed through right femoral vein (Fig. 1). The length of the migrated piece was 8cm, and no thrombus was observed at the tip (Fig. 1). No major complication occurred during and after the procedure and the patient was discharged on the next day. This is a unique case because spontaneous breakage of venous access devices is very rare and patients are usually symptomatic. DiscussionTotally implantable venous devices have been used increasingly in cancer patients since the mid-1980s. TIVDs facilitate effective long-term chemotherapy as well as parenteral nutrition, fluid replacement, and frequent blood sampling.However, TIVDs are not without complications. Early complications include incorrect position, improper a...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
