PURPOSE To describe the candy-plug technique using an Excluder aortic extender for distal occlusion of a large false lumen aneurysm in chronic aortic dissection. TECHNIQUE A 60-year-old female patient with a history of chronic type B aortic dissection and high-dose steroid use for Churg-Strauss syndrome developed a large 6.2 cm maximum diameter false(More)
Endovascular aortic repair (EVAR) requires further intervention in 20-30 % of cases, often due to type II endoleak (T2EL). Management options for T2EL include transarterial embolization, direct puncture (DP), or transcaval embolization. We report the case of an 80-year-old man with T2EL who successfully underwent DP embolization. Embolization by DP was(More)
We present a 52-year-old male with a syphilitic aortic arch aneurysm accompanied by relevant extensive cerebral infarction. He was admitted to a local hospital for sudden loss of consciousness, where he was diagnosed with serious cerebral infarction. During his treatment, a multilocular aortic arch aneurysm involving the arch vessels was found incidentally.(More)
OBJECTIVE Traumatic rupture of the thoracic aorta is a life-threatening injury requiring urgent surgical intervention. Despite recent improvements in resuscitation and emergency operative techniques, the outcomes of patients with multiple injuries are still associated with a high mortality rate. We retrospectively examined the preoperative demographic data,(More)
A man in his 80s underwent urgent endovascular aortic repair (EVAR) for a ruptured abdominal aortic aneurysm (RAAA). Surgery was completed without apparent complications, and the patient was returned to the Cardiac Care Unit. Two hours later, he again developed shock, and contrast-enhanced Computed Tomography showed extravasation from a type II endoleak(More)
A woman in her 80s with an infrarenal aortic aneurysm was scheduled for endovascular aortic repair (EVAR). The aneurysm had a severely angulated neck (SAN), and the Zenith Flex device was selected. Completion angiography showed migration of the main body resulting in right renal artery stenosis. A Palmaz genesis was placed across the renal orifice. The(More)
The survival rate of cardiac rupture due to blunt trauma is generally low. We experienced a case with right ventricular rupture due to blunt trauma. The patient was a 49-year-old man who was crushed in a traffic accident and transported to a local hospital in a shock state. He was diagnosed with cardiac tamponade due to cardiac rupture, and for pericardial(More)
In patients with coronary arteries that are deeply buried in the myocardium and fat, it is difficult and sometimes risky to expose them for off-pump coronary artery bypass grafting (OPCAB), leading to unavoidable conversion to conventional coronary artery bypass grafting (C-CABG) to ensure their safety. We have developed a new search procedure for these(More)
Chronic expanding hematoma(CEH)was first recognized by Reid in 1980. It begins to expand chronically more than 1 month after surgery or trauma, which is considered the possible cause of bleeding. It resembles chronic subdural hematoma. Most of the reports on CEH are those in the thoracic cavity or muscles, and few are in the pericardial cavity after open(More)
In-situ right gastroepiploic artery (RGEA) has been used as one of the reliable conduits for coronary artery bypass grafting (CABG). We report a case of thoracoabdominal aortic aneurysm (TAAA) repair in a patient who had previous CABG using the RGEA graft. There is a great potential risk for critical myocardial ischemia when performing open repair for TAAA(More)
