1/236. Endovascular stent graft repair of aortopulmonary fistula.

    Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula. ( info)

2/236. Treatment of a large congenital coronary fistula with coil embolization.

    A 77-year-old woman suffering from progressive dyspnea and chest pain for 2 1/2 years was admitted to hospital. There were no ECG changes at exercise test and a dobutamine stress echocardiography was normal. At catheterization, right-sided pressures were within normal limits. coronary angiography revealed a congenital coronary fistula, 3-4 mm in diameter, from the left anterior descending artery to the proximal pulmonary artery. There was no significant rise in blood oxygen saturation in the pulmonary artery. Transcatheter coil embolization was performed in the distal part of the tortuous fistula. Flow ceased within minutes, demonstrating the feasibility and efficacy of this technique for treating large fistulas. ( info)

3/236. cesarean section in a mother with uncorrected congenital coronary to pulmonary artery fistula.

    PURPOSE: We report a case of a 33 yr old woman with pulmonary hypertension secondary to uncorrected right coronary artery to pulmonary artery fistula who underwent two successful operative deliveries under general anesthesia. CLINICAL FEATURES: This woman underwent an emergency Caesarean section at 32 wk gestation because she presented in NYHA Class IV, heart failure and premature labour. She did not have antenatal follow-up. For her second pregnancy, she was managed from the first trimester of pregnancy by the cardiologist, obstetrician and anesthesiologist. She received oral furosemide and digoxin from eight weeks gestation. pregnancy was managed to term before she progressed to NYHA Class IV and cardiac failure at 37 wk gestation. She had a Caesarean section under general anesthesia. She received rapid sequence induction of anesthesia and tracheal intubation with 0.1 mg x kg(-1) etomidate, 2 mg x kg(-1) succinylcholine and maintenance with nitrous oxide 50% in oxygen, isoflurane 1% and 0.1 mg x kg(-1) vecuronium. fentanyl, 2 microg x kg(-1) helped to obtund the hypertensive response to intubation. analgesia was provided with 1 mg x kg(-1) morphine. Glyceryl trinitrate infusion, 10-30 microg x min(-1) was used in addition to the anti-heart failure therapy. End-tidal capnography, electrocardiogram, pulse oximetry, continuous arterial blood pressure and pulmonary arterial catheter provided hemodynamic monitoring. The lungs were mechanically ventilated for 24 hr postoperatively. She received anti-heart failure therapy which she continued after discharge. She was NYHA class II upon discharge. She defaulted from further follow-up. CONCLUSION: Although the literature advocates, in this situation, controlled vaginal delivery utilising epidural analgesia, we describe the successful outcome for operative delivery under general anesthesia in a patient with secondary pulmonary hypertension and heart failure.

4/236. Catheter-based techniques for closure of coronary fistulae.

    This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery. ( info)

5/236. Successful closure of coronary-bronchial artery fistula with vein graft-coated stent.

    A coronary-bronchial fistula and aneurysmal dilatation of the proximal part of the fistula was successfully closed using an autologous vein graft-coated stent (Palmaz-Schatz stent). This is the first report that demonstrates the feasibility of the vein-coated stent for the treatment of congenital disease. ( info)

6/236. Coronary-to-bronchial artery communication: report of two patients successfully treated by embolization.

    We report two cases of coronary-to-bronchial artery communication responsible for coronary steal. In both cases the anastomosis originated from the proximal circumflex artery and developed because of bronchiectasis. In both cases closure of the anastomosis was achieved successfully by embolization. To date, the patients remained free from symptoms. ( info)

7/236. An unusual case of bilateral coronary artery fistulas--a case report.

    The authors report an unusual case with bilateral coronary artery fistulas at the origin of the coronary cusps. The diagnostic technique and management are discussed. ( info)

8/236. Histopathologic study of presumed parafoveal telangiectasis.

    PURPOSE: To report the postmortem histopathologic features that closely resemble the clinical features of parafoveal telangiectasis. methods: light and electron microscopy. RESULTS: Histopathologic features included macular edema; telangiectatic vessels; retinal, subretinal, and superficial retinal neovascularization; retinal pigment epithelial hyperplasia around neovascular aggregates; retinal-choroidal vascular anastomosis; and superficial pigmented cells with lipofuscin. CONCLUSION: The postmortem histopathologic findings in a 36-year-old woman with down syndrome and other systemic conditions correlate with features noted in previous reports of presumed parafoveal telangiectasis.

9/236. Coronary artery aneurysm associated with fistula in adults: collective review and a case report.

    Coronary artery fistulae (CAF) are infrequent congenital anomalies. The combination of coronary artery aneurysms and coronary artery fistulae (coronary artery aneurysm associated with fistula, CAAAF) is extremely rare, and only 50 cases, including the current case, have been reported. Coronary artery fistulae may result in coronary ischemia, congestive heart failure, and endocarditis. Complications of coronary artery aneurysms include thrombosis, distal emboli, and aneurysm rupture. aneurysm repair, fistulous closure and/or coronary artery bypass grafts are definite treatments for CAAAF. We present here a 72-year-old female with CAAAF. Furthermore, all reported CAAAF cases are reviewed. ( info)

10/236. Surgical treatment of a coronary artery fistula with concomitant saccular coronary artery aneurysm: a case report.

    An extremely rare case of a coronary artery fistula with a concomitant saccular aneurysm is presented. A 65-year-old woman, who had a history of chest bruising 5 years earlier, suffered from chest pain, which was diagnosed as being due to left coronary artery-pulmonary artery fistulae concomitant with a giant saccular coronary artery aneurysm. Suture closure of the afferent coronary artery to the aneurysm, aneurysmorrhaphy, and transpulmonary closure of coronary artery-pulmonary artery fistulae were performed. The postoperative course was uneventful and the patient was well at 3 months after the operation. Because the risk of surgery appears to be less than the potential development of fatal complications, it is recommended for the treatment of coronary artery fistula with a concomitant saccular aneurysm.
