Abstract PDF: Persistent hypoxemia following myocardial infarction can be challenging to manage and often requires considering uncommon etiologies such as extracardiac shunts. This case report describes a 78-year-old man with persistent hypoxemia post-myocardial infarction, which was ultimately attributed to a large pulmonary arteriovenous malformation (AVM). The patient presented with cardiogenic shock and underwent successful revascularization. Despite clinical improvement, the hypoxemia persisted, prompting further evaluation. Bedside saline contrast echocardiography and computed tomography confirmed the presence of a large pulmonary AVM, explaining the uncorrectable hypoxemia. This case underscores the importance of considering extracardiac shunts in patients with refractory hypoxemia and illustrates the utility of bedside imaging in such situations.

Fistulas between the arteries and the gastrointestinal tract are rare but can be fatal. We present a case of an ilioenteric fistula between the left external iliac artery and sigmoid colon caused by radiotherapy for cervical cancer, which was treated with endovascular management using a stent graft. A 38-year-old woman underwent concurrent chemoradiotherapy for cervical cancer recurrence. Approximately 9 months later, the patient suddenly developed hematochezia. On her first visit to the emergency room of our hospital, computed tomography (CT) images did not reveal extravasation of contrast media. However, 8 hours later, she revisited the emergency room because of massive hematochezia with a blood pressure of 40/20 mmHg and a heart rate of 150 beats per minute. At that time, CT images showed the presence of contrast media in almost the entire colon. The patient was referred to the angiography room at our hospital for emergency angiography. Inferior mesenteric arteriography did not reveal any source of bleeding. Pelvic arteriography showed contrast media extravasation from the left external iliac artery to the sigmoid colon; this was diagnosed as an ilioenteric fistula and treated with a stent graft. When the bleeding focus is not detected on visceral angiography despite massive arterial bleeding, pelvic arteriography is recommended, especially in patients with a history of pelvic surgery or radiotherapy.

Abstract PDF

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.

Abstract PDF: Cardiogenic embolic stroke accounts for approximately 20% of ischemic strokes and the likelihood of its recurrence is high. Paradoxical embolism may be an important cause of cardioembolic stroke, which can be evaluated through multiple diagnostic modalities including transesophageal echocardiography (TTE) or transcranial Doppler. A persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly, which mainly drains to the right atrium via the coronary sinus. Although rare, PLSVC draining into the left heart predisposes the patient to paradoxical embolism through a right-to-left shunt. We report on a 78-year-old female patient with an ischemic stroke associated with PLSVC draining into the left atrium through the pulmonary vein, which was investigated via TTE with an agitated saline test and computed tomography.

Abstract PDF

BACKGROUND
The purpose of this study was to determine the effectiveness of a percutaneously placed self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. MATERIALS AND METHODS: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self- expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. RESULTS: There were 4 cases of Bismuth type II, 21 cases of Bismuth type IIIa, 8 cases of Bismuth type IIIb and 15 cases of Bismuth type IV. Stent placement was technically successful in all patients. All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage rate of 91.1%. There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and Median Survival Time Were 303 Days (Range, 60~815) And 338 Days (Range, 60~1175), Respectively. CONCLUSION: Placement of a percutaneous metallic stent is an effective and safe method for palliation of patients with hilar cholangiocarcinoma.
