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.

Colonoscopy-Induced Acute Diverticulitis

Even though colonoscopy is a common and widely performed procedure, it can cause many complications. If any sign of inflammation is observed, a perforation or postpolypectomy coagulation syndrome should be considered. Diverticulitis, a very rare complication with an incidence of 0.04% to 0.08%, also can occur after the diagnostic and therapeutic procedure. We report a case of acute diverticulitis after colonoscopy, diagnosed with typical computed tomography findings after excluding other complications. The patient was treated in the same manner as for complicated diverticulitis, with bowel rest, hydration, and broad-spectrum antibiotics. Acute diverticulitis as a rare complication can occur following prolonged colonoscopy or colonoscopic polypectomy, especially in those with additional risk factors such as obesity and smoking.

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.

A Case of Hepatic Involvement in Hereditary Hemorrhagic Telangiectasia Presenting as High Output Heart Failure / 계명의대학술지

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, is a rare autosomal dominant vascular disorder involving arteriovenous malformation. HHT is characterized by recurrent epistaxis, cutaneous telangiectasia, and visceral arteriovenous malformations. Hepatic arteriovenous malformation can lead to high output heart failure. We report a case of hereditary hemorrhagic telangiectasia patient who complained dyspnea and edema on both lower extremity.

Gallstone Ileus in 83-Year-Old Woman

Gallstone ileus is a rare complication of the biliary stone, occurring in 0.3-0.5% of patients with cholelithiasis. The mortality rate is high at 12-27% and early diagnosis and prompt management can improve its prognosis. An 83-year-old woman was admitted to the hospital with abdominal pain. The patient previously had a hysterectomy and had received radiation therapy for uterine cancer. Plain abdominal x-ray showed typical findings of small bowel ileus with step ladder patterns. Computed tomography (CT) scan revealed biliary-enteric fistula with a 3-cm-sized gallstone in the jejunal loop. Surgical treatment was planned but due to the patient's wish, conservative treatment was provided for 10 days. In the follow-up CT scan, the stone had moved to the distal ileum but intestinal perforation was suspected. Ileocecectomy and adhesiolysis were performed and the patient recovered fully. Here we report a case of gallstone ileus that was treated by surgical removal after 10 days of conservative treatment.
