Retrieval of a dislodged and dismounted coronary stent; using a rendezvous and snare technique at the brachial artery level via femoral approach / 영남의대학술지

Coronary stent dislodgement during percutaneous coronary intervention, which occurs when the stent is passed through tortuous and calcified lesions, is not a rare complication. Without proper treatment, such as fixing with another stent in the coronary artery or removing the undeployed stent from the coronary artery or systemic artery system, this complication can cause serious problems. We experienced the unusual situation of a dismounted and dislodged coronary stent, in which retrograde retrieval to the radial artery was impossible during transradial coronary intervention. We report on use of a rendezvous and snare technique at the brachial artery level via femoral puncture, which resulted in resolution without surgery.

Sudden Deafness in a Patient with Chronic Hepatitis C Treated with Peginterferon and Ribavirin Combination Therapy / 대한내과학회지

Combined peginterferon and ribavirin therapy for chronic hepatitis C is associated with several adverse side effects, but sudden deafness is uncommon. Here we report the case of a 62-year-old female with chronic hepatitis C (genotype 1b) who developed sudden deafness after completing 12 months of treatment with peginterferon alpha2a (180 microg/week) and ribavirin (1,000 mg/day). Pure-tone audiometry revealed a right-sided sensorineural hearing loss, which did not respond to 2 weeks of systemic corticosteroid therapy. Six months after the end of treatment for chronic hepatitis C, her qualitatively determined hepatitis C virus RNA level was 121,000 IU/mL. Following therapeutic failure, the patient was observed without retreatment for chronic hepatitis C or her hearing loss for a period of 12 months, during which time her hearing recovered almost completely.

Mechanical Thrombectomy by the Rolling Technique Using a Coronary Wire in a Patient with Recurrent Inferior Vena Cava Filter Thrombosis / 대한내과학회지

A permanent inferior vena cava (IVC) filter with anti-coagulation therapy may be considered in patients with recurrent pulmonary embolism. IVC filter thrombosis is a challenging clinical problem. Here, we report our experience in treating one such patient using mechanical thrombectomy via the rolling technique with a 0.014-inch coronary wire.
