11/271. Thoracoabdominal aortic aneurysm combined with aortic occlusion.

    The case of a 73-year-old woman with aneurysms of the thoracoabdominal aorta and distal arch, combined with aortic occlusion, is reported. Cannulation from the femoral artery was not possible because of the aortic occlusion. Blood supply to the abdominal viscera and lower extremities was achieved only by selective perfusion from the celiac artery, superior mesenteric artery, and bilateral renal arteries. A unique choice of selective perfusion for distal circulatory support is described.

12/271. A case of aortoduodenal fistula occurring after surgery and radiation for pancreatic cancer.

    The patient was a 58-year-old woman given curative treatment (pancreatectomy (body and tail) intraoperative irradiation (25 Gy)) on the basis of a diagnosis of pancreatic carcinoma. Having a favorable postoperative course, she was discharged 24 days after surgery. A week after discharge, she was readmitted for a hemorrhagic gastric ulcer. She was later discharged again on conservative treatment, and followed up at the outpatient clinic, but nine months postoperatively, was readmitted complaining of loss of appetite and abdominal pain. Subsequent tests revealed stricture of the horizontal portion of the duodenum with distension oral to the stricture. Around the celiac artery, the paraaortic lymph nodes were swollen, and a diagnosis of stricture due to recurrent pancreatic carcinoma was made. On the day before bypass surgery was scheduled, the patient vomited blood, so the operation was postponed, conservative treatment such as blood transfusion was administered, and emergency angiography was performed simultaneously. The findings were an aortic pseudoaneurym 1 cm in diameter immediately below the origin of the superior mesenteric artery and between the left and right renal arteries, and a hemorrhage, caused by an aortoduodenal fistula, issuing from the horizontal portion of the duodenum. hemostasis via a laparotomy was judged difficult, and so an indwelling stent-graft in the aorta was tried to stanch the blood, but without success. Another stent then had to be inserted within the first, thus stopping the flow, but the blood supply to the celiac artery, the superior mesenteric arteries and the renal arteries was impaired, and the patient died about six hours later. Postmortem examination revealed aortoduodenal fistula without recurrence of the carcinoma. The duodenal wall around the fistulous tract showed delayed radiation changes with deep ulceration. The intraoperative radiation may have played an important part in the formation of the fistula.

13/271. Aortoesophageal fistula caused by foreign body.

    Aortoesophageal fistula is rare. A woman who developed aortoesophageal fistula after swallowing a fish bone developed hematemesis. 7 days later, we resected a false aneurysm near the left subclavian artery and repaired this section twice. Despite these measures, the woman died on hospital day 21. The clinical diagnosis was massive hematemesis from an infected aortic wall. The method of diagnosis, control of infection, and operative repair of aortoesophageal fistula are discussed.

14/271. Coil embolization of a false aneurysm with aorto-cutaneous fistula after prosthetic graft replacement of the ascending aorta.

    AIM: To report palliative embolization of a false aneurysm over the distal suture line of an ascending aorta graft replacement. MATERIAL AND METHOD: A 78-year-old male patient was admitted for increasing bleeding of a chronic manubrium ulceration, 20 months after coronary artery bypass complicated by perioperative ascending aorta dissection requiring prosthetic graft replacement. One month later, he underwent epiploplasty for a mediastinitis followed by long-term antibiotic therapy. Five months later, he presented with a manubrium ulceration of the sternotomy. Spiral computerized tomography (CT) and aortography revealed a 20 mm anterior peri-prosthetic false aneurysm with a wide neck. Advanced age, active mediastinitis and patient's objection led us to perform percutaneous occlusion according to the Moret remodeling technique while protecting the coils release with balloon catheter inflation. RESULTS: No post-operative complication was observed and at 1-year follow-up the patient was doing well with no recurrent bleeding. magnetic resonance imaging (MRI) and spiral CT controls confirmed coils stability without any internal flow. CONCLUSION: Percutaneous coils embolization of a large false aneurysm in the ascending aorta can be a palliative treatment in a surgically unsuited patient.

15/271. Aortic septal defect and coronary-systemic micro-fistulae.

    This report concerns a 32-year-old man, who at the age of 11, had an aortic septal defect with severe pulmonary hypertension. The defect was partially closed and the patient was left with a continuous murmur, an a-v shunt and marked diminution of pulmonary hypertension. Five years later he was asymptomatic, auscultation was normal and no shunt was found at cardiac catheterization. At 32 years of age, although asymptomatic he had abnormal "T" waves, and a selective coronary angiography demonstrated micro-fistulae involving the anterior descending coronary artery. It is suggested that these fistulae may be responsible for the abnormality of ventricular repolarization.

16/271. Aorto-right artrial fistula: a rare complication of aortic dissection.

    We describe the successful surgical repair of an acute aortic dissection that had caused an aorto-right atrial fistula in a 67-year-old man. The patient was admitted to the hospital on an emergency basis because of severe heart failure. The diagnosis of acute aortic dissection with rupture into the right atrium was confirmed by use of intraoperative transesophageal echocardiography, although rupture of a sinus of valsalva aneurysm into the right atrium had been suggested initially by 2-dimensional and Doppler transthoracic echocardiography. At surgery, we found the patient to have aortic arch dissection with complete separation of the right coronary artery from the sinus of valsalva and a false lumen that had ruptured into the right atrium. The aortic arch was repaired directly. The ascending aorta was successfully replaced with a composite graft. Aortic dissection with rupture into the right atrium is extremely rare and leads to death rapidly. As shown in this case, such a condition might be mistaken for an aneurysmal rupture of the sinus of valsalva, with use of transthoracic echocardiography alone. Transesophageal echocardiography is a useful noninvasive method to further define or confirm the diagnosis. Early surgical intervention is necessary in patients with this condition to prevent profound shock and end-organ failure.

17/271. Aortoenteric fistula. A complication of renal artery bypass graft.

    The incidence of gastrointestinal bleeding secondary to aortoenteric fistula has increased in recent years consequent to more frequent aortic reconstructive procedures. It is necessary to approach any such patient with this diagnostic consideration in mind, since early specific therapy may decrease the mortality. In this setting, there is usually sufficient time available to perform definitive tests to establish the correct diagnosis. We report a 37-year-old patient in whom aortoenteric fistula developed following a renal artery bypass graft.

18/271. Acute occlusion of an abdominal aortic aneurysm--case report and review of the literature.

    Acute thrombosis of an abdominal aortic aneurysm (AAA) is a surgical emergency. Only 44 cases have been reported in the literature. The mechanism of the thrombosis has not been delineated. The proposed etiologies include propagation of thrombus from distal artery occlusion, cardiac thromboembolism, and dislodgment of a mural thrombus. patients often present bilateral lower extremity ischemia, mimicking a saddle embolism. Systemic heparinization immediately after diagnosis and prompt surgical revascularization can reduce the mortality rate. The authors present a patient with sudden thrombosis of an AAA who was successfully treated with an axillobifemoral bypass graft. All published cases of thrombosed AAAs are analyzed.

19/271. aortic valve replacement for the calcified ascending aorta in homozygous familial hypercholesterolemia.

    A 72-year-old woman who had been diagnosed as homozygous familial hypercholesterolemia was admitted for chest discomfort. Computed tomography and cardiac catheterization revealed severe calcification of the aortic root and a high grade stenosis of the proximal right coronary artery. aortic valve replacement concomitant with coronary artery bypass was done using temporary hypothermic circulatory arrest. This is preferred method when dealing the calcified aorta.

20/271. Retrograde nontransseptal balloon mitral valvuloplasty by the brachial artery approach.

    Retrograde nontransseptal balloon mitral valvuloplasty is a purely transarterial technique for percutaneous treatment of mitral stenosis. We report the first use of this technique via the brachial artery for a patient with aortoiliac atherosclerosis, and we comment on the difficulties and perspectives of this approach.
