1/21. Pseudoaneurysm of the abdominal aorta: evaluation with virtual angioscopy of spiral-CT data sets.We describe a case of graft-related pseudoaneurysm of the abdominal aorta evaluated with spiral CT and DSA. Spiral CT data sets were processed to obtain surface-rendered internal views (virtual angioscopy, VA) of the graft and the pseudoaneurysm, and to demonstrate from inside the lumen the site of dehiscence. A jet flow phenomenon inside the pseudoaneurysm was observed at DSA. Spiral-CT axial images, multiplanar volume reconstructions with maximum intensity projections, and shaded surface display showed the site of rupture. The VA findings were: (a) from inside the graft lumen, the evidence of a communication canal between the graft and the pseudoaneurysm; and (b) from inside the pseudoaneurysm, the presence of a jet flow. The VA findings showed good correlation with those obtained with the other imaging techniques.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/21. 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 = 0.97238570040055keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/21. False aneurysm of the peroneal artery: an unusual complication of femoro-peroneal bypass grafting.Non-traumatic false aneurysm formation involving the native crural vessels is rare. We present the case of a false aneurysm of the native peroneal artery, which complicated femoro-peroneal bypass grafting. It seemed most likely to be of an infective aetiology, arising as a consequence of contiguous methicillin resistant staphylococcus aureus wound infection. This was previously unreported in the literature. Successful management was achieved by primary suture, local wound debridement, excision of the distal graft and replacement with an interposition vein graft through uninfected tissue planes.- - - - - - - - - - ranking = 0.055228599198899keywords = aneurysm (Clic here for more details about this article) |
4/21. Pseudoaneurysm following axillo-femoral by-pass: unusual presentation.An unusual presentation of a false aneurysm following axillo-femoral by-pass is reported. The leak at the femoral anastomosis dissected the fibrous tissue along the Dacron tube, causing the peculiar appearance of this case. A brief review of recent literature regarding the etiology of this complication is included.- - - - - - - - - - ranking = 0.046023832665749keywords = aneurysm (Clic here for more details about this article) |
5/21. Patch corrugation on duplex ultrasonography may be an early warning of prosthetic patch infection.Four of 10 patients presenting with prosthetic patch infection after carotid endarterectomy (CEA) were noted to have Duplex evidence of 'corrugation' of the prosthetic patch, without false aneurysm formation. In three, corrugation preceded diagnosis of overt patch infection by up to 11 months. In the fourth patient, awareness of the potential significance of patch corrugation enabled timely treatment of an otherwise unrecognized patch infection. Even if other imaging modalities are normal, the presence of patch corrugation on Duplex should prompt the surgeon to (at least) consider the possibility of patch infection.- - - - - - - - - - ranking = 0.0092047665331498keywords = aneurysm (Clic here for more details about this article) |
6/21. Ascending aortic aneurysm after pediatric heart transplantation: case report of an unusual complication.A 28-month-old boy, weighing 11 kg, with severe dilated cardiomyopathy, was transplanted on December 1995. hypertension and supraventricular tachycardia were detected in the immediate post-operative period, with favorable outcome. After 5 months of clinically asymptomatic follow-up, a dilation in the ascending aorta was observed on routine echocardiogram. Nuclear magnetic resonance imaging (NMRI) confirmed an ascending aortic aneurysm, with a diameter of 38 mm. An operation was performed, a bovine pericardium patch was sutured with reconstruction of the aortic wall, excluding the aneurysm. Good recovery was obtained and the child was discharged on Day 7 postoperatively. A post-operative echocardiogram showed absence of the aortic aneurysm and good surgical results. Another NMRI was done 5 months later, showing an intact ascending aorta. After 64 months, the patients clinical condition was confirmed as normal by echocardiogram. Surgical treatment was successful and the positive results have been maintained.- - - - - - - - - - ranking = 0.064433365732049keywords = aneurysm (Clic here for more details about this article) |
7/21. Late onset renal allograft anastomotic pseudoaneurysm with absent Doppler signal.A large extrarenal pseudoaneurysm, originating from the arterial anastomosis of a renal allograft, occurred spontaneously 7 years after transplantation in a 29-year-old diabetic patient. Although the scintigraphic examination was diagnostic of a pseudoaneurysm, pulsed Doppler and color coded Doppler ultrasound failed to demonstrate a Doppler signal, suggesting erroneously a nonvascular fluid collection. The role of scintigraphy combined with duplex ultrasound in this rare but potentially fatal complication of renal transplantation is discussed.- - - - - - - - - - ranking = 1.1558171206409keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/21. Acute aortic occlusion as a late complication of coarctation repair.Late morbidity and mortality following surgical correction of coarctation of the aorta in adults are primarily related to associated cardiovascular disease, especially persistent systemic hypertension and its sequelae. complications related to the site of coarctation repair are relatively uncommon in this age group and include residual and recurrent coarctation and aneurysm formation. An unusual case is presented in which dehiscence of the proximal suture line of a Dacron tube graft resulted in a flap-valve effect, pseudoaneurysm formation, and acute functional occlusion of the aorta. The angiographic findings are described and the relevant literature reviewed.- - - - - - - - - - ranking = 0.20184095330663keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/21. Infected saphenous vein coronary artery bypass graft with mycotic aneurysm. Fatal dehiscence of the proximal anastomosis.A 33-year-old man underwent coronary artery bypass graft surgery for relief of angina pectoris. His postoperative course was complicated by hemorrhage and mediastinitis. death, which occurred after severe hemorrhage from the operative site, was shown at autopsy to be caused by dehiscence of the proximal anastomosis of the right coronary artery graft. The same graft also had a mycotic aneurysm in its midportion. Graft disruption thus appears to be a potential complication of mediastinal infection in patients with saphenous vein bypass grafts.- - - - - - - - - - ranking = 0.046023832665749keywords = aneurysm (Clic here for more details about this article) |
10/21. The pectoralis myocutaneous flap for salvage of necrotic wounds.The authors have utilized six pectoralis major myocutaneous flaps in attempts to salvage extensive necrotic wounds of the pharynx and neck. The flap was employed in the following situations: massive necrosis of the entire neck skin with both carotid artery systems exposed, radiation necrosis of the neck skin with exposure of carotid artery, dehiscence of gastric pull-up from pharynx with resultant carotid exposure, failed trapezius flap in a radionecrotic oral cavity, and two cases of pharyngocutaneous fistula with extensive soft tissue necrosis. These flaps achieved healing in all cases. One death occurred 3 weeks following complete cutaneous healing secondary to a ruptured carotid pseudoaneurysm. One flap underwent total skin loss but the entirety of the muscle survived and the fistula was successfully closed with the back of the muscle being subsequently skin grafted. One case of dehiscence of the flap from oral mucosa resulted in a minor exposure of mandible with limited osteoradionecrosis controlled by topical means. This flap has performed extremely well in these precarious and difficult situations that previously may not have been salvageable. It has also been effective in abbreviating the required hospitalization and wound care. We conclude that the pectoralis myocutaneous flap should be the primary choice for the management of extensive postsurgical wound necrosis.- - - - - - - - - - ranking = 0.19263618677348keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
