1/501. 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.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
2/501. In situ repair of a secondary aortoappendiceal fistula with a rifampin-bonded Dacron graft.Secondary aortoenteric fistulas remain challenging diagnostic and therapeutic problems. Although the duodenum is most frequently involved, other intestinal segments are possible sites for fistulization. We report here a case of graft-appendiceal fistula revealed by recurrent gastrointestinal bleeding 11 years after abdominal aortic aneurysm replacement. The preoperative diagnosis was not achieved by endoscopy or imaging assessment. Despite recommended principles of total graft excision and extraanatomic bypass, appendectomy and in situ rifampin-bonded graft reconstruction were performed because of the advanced age and poor arterial runoff. The postoperative course was uneventful and the patient remains well 17 months after operation.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
3/501. Successful repair of an idiopathic spontaneous aortoduodenal fistula.A case of idiopathic spontaneous aortoduodenal fistula treated surgically is reported. This case is probably the first successful repair of an idiopathic fistula to be recorded in the literature. The difficulty in diagnosis and possible aetiology are discussed.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |

5/501. Aortobronchial fistula after coarctation repair and blunt chest trauma.A 34-year-old man had development of an aortobronchial fistula 17 years after patch aortoplasty for correction of aortic coarctation and 5 years after blunt chest trauma, an unusual combination of predisposing factors. The clinical presentation, characterized by dysphonia and recurrent hemoptysis, and the surgical findings suggested the posttraumatic origin of the fistula, which was successfully managed by aortic resection and graft interposition under simple aortic cross-clamping, associated with partial pulmonary lobectomy. When hemoptysis occurs in a patient with a history of an aortic thoracic procedure, the presence of an aortobronchial fistula should be suspected. early diagnosis offers the only possibility of recovery through a lifesaving surgical procedure.- - - - - - - - - - ranking = 1.1666666666667keywords = fistula (Clic here for more details about this article) |
6/501. Primary aorto-duodenal fistula secondary to infected abdominal aortic aneurysms: the role of local debridement and extra-anatomic bypass.Gastrointestinal bleeding secondary to spontaneous rupture of an infected abdominal aortic aneurysm into the duodenum is a rare and highly lethal clinical occurrence, representing roughly a third of all primary aortoduodenal fistulas. Diagnosis is problematic due to the subtleties in the clinical presentation and course, and surgical treatment is usually delayed, representing a challenge even for the experienced vascular surgeon. The overall mortality is over 30% and the operative approaches are still controversial. Two cases of ruptured infrarenal aortic aneurysms complicated with aortoduodenal fistula were recently treated at our institution. Bacterial aortitis was documented by arterial wall cultures positive for klebsiella and salmonella species respectively. The clinical courses and outcomes of the two patients (one survivor ) treated with retroperitoneal debridement and extra-anatomic bypass and a review of the modern surgical treatment are herein described.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
7/501. Aortocaval fistula: diagnosis with carbon dioxide angiography.Aortocaval fistulas are an uncommon complication of atherosclerotic aneurysms that can present with a variety of clinical symptoms. Many of these patients present with oliguric renal failure, a contraindication for the use of iodinated contrast in radiological studies. We present a case of an aortocaval fistula diagnosed by using carbon dioxide gas without the use of traditional contrast media.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
8/501. Successful surgical treatment of aortogastric fistula after an esophagectomy and subsequent endovascular graft placement: report of a case.An aortogastric fistula is a rare but fatal complication after an esophagectomy and intrathoracic esophagogastric anastomosis. A 54-year-old man underwent an esophageal resection due to carcinoma in his lower esophagus. The alimentary tract continuity was restored by intrathoracic esophagogastric anastomosis. Forty-six days later, he suffered a massive hematemesis due to an aortogastric fistula which had formed at the esophagogastric suture line. The fistula was surgically obliterated twice, but each operation was followed by pseudoaneurysm formation. The patient was finally successfully treated with an endovascular stent graft placement. This is the first report of a patient surviving after developing this complication.- - - - - - - - - - ranking = 1.1666666666667keywords = fistula (Clic here for more details about this article) |
9/501. Aortoduodenal fistula arising from the dilatation of a knitted Dacron graft: report of a case.A fatal aortoduodenal fistula occurred in a 72-year-old man who underwent a repair of an abdominal aortic aneurysm 16 years previously with a 20 x 10 mm bifurcated knitted Dacron graft. The aortic part of his bifurcated graft had dilated to 40 mm in diameter, with a discrepancy of 20 mm in the diameter between the graft and infrarenal aorta. The fourth portion of the duodenum adhered to the left side of the anastomosis, where the aortoenteric fistula had occurred. We believe that the graft dilatation was the cause of the anastomotic failure, although other factors such as atherosclerotic degeneration of the host aorta should also be considered. Knitted Dacron grafts that have been implanted for more than 10 years should therefore be monitored carefully because they have an inherent tendency to dilate, especially those manufactured before 1981.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
10/501. Aortoduodenal fistula: a late complication of intraluminal exclusion of an infrarenal aortic aneurysm.During recent years, considerable clinical experience has been gained with endoluminal stent-graft procedures. Several studies have shown promising results up to a period of 4.5 years. However, long-term follow-up studies are still limited. Late endoleaks caused by stent-graft migration, disconnection of single components in modular stent-grafts, and limb thrombosis have been observed as long-term complications. We report a case in which a migrated and kinked bifurcated stent-graft caused an aortoduodenal fistula 20 months after stent-graft insertion. To our knowledge, such a complication has not been reported before.- - - - - - - - - - ranking = 0.83333333333333keywords = fistula (Clic here for more details about this article) |
