1/53. hematuria from arteriovesical fistula: unusual presentation of ruptured iliac artery aneurysm.iliac artery aneurysm rupture can be rapidly fatal if not diagnosed immediately. These aneurysms usually present in patients with other aneurysmal diseases of the aortoiliac arterial system. If not diagnosed and surgically repaired, iliac artery aneurysms can proceed to expand and ultimately rupture, usually presenting with back, flank, or abdominal pain and, possibly, signs of systemic shock. We present an unusual case report of a common iliac artery aneurysm rupture presenting as gross hematuria due to an arteriovesical fistula. Only three other cases of arteriovesical fistulae have been reported previously. Unlike the case presented, all three of these cases involved trauma or surgical instrumentation or manipulation of the bladder.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
2/53. Unusual origin and fistulization of an aortic pseudoaneurysm: "off-pump" surgical repair.Aortic pseudoaneurysm is an unusual complication of cardiac operations. The origin depends on the site of arterial wall disruption. rupture into the right side of the bronchial tree is an exceedingly rare evolution. Repair is commonly performed using cardiopulmonary bypass. In our report a male patient underwent two procedures for aortic dissection, and 6 months after the second operation massive hemoptysis appeared abruptly. A false aneurysm rose from a graft-to-graft anastomotic site and ruptured into a segmental bronchus of the right upper lobe. Repair was performed without cardiopulmonary bypass.- - - - - - - - - - ranking = 0.5767804562038keywords = upper (Clic here for more details about this article) |
3/53. Left coronary artery-left ventricular fistula with acute myocardial infarction, representing the coronary steal phenomenon: a case report.A 59-year-old man presented with a left anterior descending coronary artery to left ventricular fistula manifesting as myocardial infarction, representing the coronary steal phenomenon. electrocardiography showed poor R progression in leads V1 through V3. The biochemical markers of myocardial injury were elevated. creatine kinase level was 509 IU/l, creatine kinase MB isoenzyme (CK-MB)47 IU/l, cardiac troponin t 0.62 ng/ml, myosin light chain 6.1 ng/ml, and myoglobin 142 ng/ml. thallium-201 myocardial perfusion imaging with dobutamine stress showed a dobutamine-induced perfusion deficit of the anteroseptal wall of the left ventricle with 0.1 mV ST-segment depression in II, III, aVF, V5, and V6. The mean left anterior descending blood flow measured with the Doppler guidewire was increased from 211 to 378 ml/min. Selective coronary arteriography showed dominant left coronary artery with the contrast medium streaming into the left ventricle via a maze of fine vessels from the distal left anterior descending coronary artery. No critical stenosis of the left anterior descending coronary artery was observed. Administration of acetylcholine 100 micrograms into the left coronary artery did not induce vasoconstriction of that artery. The fistula terminating in the left ventricle was ligated surgically and the patient became free of chest pain. thallium-201 myocardial perfusion imaging with dobutamine stress revealed no perfusion deficit of the anteroseptal wall of the left ventricle. The presence of coronary steal phenomenon was detected by dobutamine stress myocardial imaging.- - - - - - - - - - ranking = 0.83119823831721keywords = chest (Clic here for more details about this article) |
4/53. Aortoduodenal fistula after endovascular stent-graft of an abdominal aortic aneurysm.Despite satisfying short- and middle-term effectiveness and feasibility, endovascular stent-grafting for abdominal aortic aneurysm is still under evaluation. We report a case of an aortoduodenal fistula after the use of this technique. Enlargement of the upper aneurysmal neck was followed by caudal migration of the major portion of the stent-graft, which resulted in kinking of the device in the aneurysmal sac. Ulcerations were found on adjacent portions of both the aneurysmal sac and the adjacent duodenum. Only the textile portion of the prosthetic contralateral limb separated the aortic lumen from the corresponding duodenal lumen. Early detection of complications after stent-grafting is essential to allow successful treatment, either surgical or endoluminal.- - - - - - - - - - ranking = 0.5767804562038keywords = upper (Clic here for more details about this article) |
5/53. 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.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
6/53. Successful transcatheter coil embolization of coronary artery fistula in an infant.Congenital coronary artery fistula is a rare anomaly that can cause several types of morbidity as well as mortality. Recently, transcatheter coil embolization for congenital coronary artery fistula has been advocated as an effective alternative to surgical repair and is associated with a low morbidity and good clinical outcome. We report a 49-day-old infant who had tachycardia, tachypnea, prolonged and interrupted feeding, cardiomegaly, and continuous murmur, and who underwent successful transcatheter coil embolization for a congenital right coronary artery fistula. At review 1 year after coil occlusion showed that serial plain chest radiographs, myocardial enzyme analysis, electrocardiography, and wall motion on echocardiography were normal.- - - - - - - - - - ranking = 0.83119823831721keywords = chest (Clic here for more details about this article) |
7/53. Primary aortoesophageal fistula: presenting as massive upper gastrointestinal hemorrhage.Primary aortoesophageal fistula is a rare cause of upper gastrointestinal bleeding. A six-year-old boy presented with massive upper gastrointestinal hemorrhage. endoscopy revealed a submucosal bulge in the esophagus with an ulcer and clot at the top. Lateral skiagram of the chest showed a posterior mediastinal mass. CT scan of the chest revealed a ruptured aortic aneurysm into the oesophagus, confirmed the diagnosis. The patient succumbed to the illness before he could be subjected to definitive treatment.- - - - - - - - - - ranking = 5.1230792138572keywords = chest, upper (Clic here for more details about this article) |
8/53. Stent-graft treatment for bleeding from a presumed aortoenteric fistula.PURPOSE: To describe a technique for the endovascular treatment of aortoenteric fistula. methods AND RESULTS: A 67-year-old man who had undergone aortobi-iliac grafting for aneurysmal disease 8 years previously presented with life-threatening upper gastrointestinal hemorrhage. endoscopy after resuscitation did not identify the source of the bleeding. Computed tomographic (CT) scanning and angiography revealed pseudoaneurysm formation at the upper anastomosis 1 cm below the renal arteries. Measurements were taken for endovascular repair. Uncomplicated emergency aortic endografting for exclusion of the pseudoaneurysm was performed using a 28-mm x 3.75-cm AneuRx device. gastrointestinal hemorrhage ceased. CT scanning at 6 months confirmed the absence of a pseudoaneurysm, and the patient remains symptom free at 18 months. CONCLUSIONS: Endovascular treatment of aortoenteric fistula may represent a technique for treating gastrointestinal hemorrhage and for lessening the morbidity and mortality of open repair.- - - - - - - - - - ranking = 1.1535609124076keywords = upper (Clic here for more details about this article) |
9/53. Endovascular repair of a presumed aortoenteric fistula: late failure due to recurrent infection.PURPOSE: To describe a case of presumed aortoduodenal fistula that was treated by endovascular implantation of a stent-graft. methods AND RESULTS: A 76-year-old man was transferred from another hospital where he had been treated for upper gastrointestinal hemorrhage over a 2-month period. Ten years previously, he had undergone aortobifemoral bypass, the right limb of which recently thrombosed. At the time of transfer, computed tomographic scanning showed a large false aneurysm between the aorta and the duodenum. endoscopy disclosed mucosal erosions in the fourth portion of the duodenum. Following implantation of 2 overlapping stent-grafts, the bleeding ceased and the false aneurysm disappeared. At no time did the patient have a fever. The patient initially did well, but 8 months after treatment, he presented with fever and chills. Recurrent infection had caused erosion of the aorta so that a large portion of the stent-graft was visible from the duodenum. The infected graft and stent-grafts were removed in a two-part operation, from which the patient recovered satisfactorily. CONCLUSIONS: Endovascular stent-grafts may have a role to play in the management of aortoduodenal fistula, if only as a temporary measure to control bleeding.- - - - - - - - - - ranking = 0.5767804562038keywords = upper (Clic here for more details about this article) |
10/53. Endovascular repair of an aortoenteric fistula in a high-risk patient.PURPOSE: To describe the endovascular repair of an aortoenteric fistula in a high-risk patient. methods AND RESULTS: A Vanguard tube stent-graft was deployed at the upper anastomotic suture line of a secondary aortoenteric fistula, successfully sealing the communication between the aorta and the third part of the duodenum without occlusion of the renal arteries. CONCLUSIONS: Endovascular stent-graft repair of aortoenteric fistulae is possible, but further evaluation of this technique will determine its role in the management of this complication.- - - - - - - - - - ranking = 0.5767804562038keywords = upper (Clic here for more details about this article) |
