1/86. Simultaneous subarachnoid hemorrhage and carotid cavernous fistula after rupture of a paraclinoid aneurysm during balloon-assisted coil embolization.We describe an iatrogenic perforation of a paraclinoid aneurysm during balloon-assisted coil embolization that resulted in simultaneous subarachnoid contrast extravasation and a carotid cavernous fistula. The causative factors specifically related to the balloon-assisted method that led to aneurysm rupture are discussed as well as strategies for dealing with this complication.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/86. Ultrasound guided percutaneous thrombin injection for the treatment of iatrogenic pseudoaneurysms.Iatrogenic aneurysms are usually postcatheterisation pseudoaneurysms of the femoral artery. Until recently, the treatment of choice was ultrasound guided compression repair. A case of pseudoaneurysm of the axillary artery, arising as a complication of pacemaker insertion in an 83 year old man is reported. Compression repair was not possible in this case, and so the aneurysm was occluded by percutaneous ultrasound guided thrombin injection directly into the aneurysm sac. Percutaneous ultrasound guided thrombin injection is a promising new minimally invasive technique for the treatment of iatrogenic pseudoaneurysms.- - - - - - - - - - ranking = 81.677248354946keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/86. Successful completion of endoluminal repair of an abdominal aortic aneurysm after intraoperative iatrogenic rupture of the aneurysm.PURPOSE: A method of achieving successful completion of endoluminal repair of an abdominal aortic aneurysm (AAA) in the presence of intraoperative iatrogenic rupture of the aneurysm is reported. methods: An 83-year-old woman with an AAA that was 7 cm in diameter was treated electively by means of endoluminal repair with a Vanguard bifurcated prosthesis (boston Scientific, Natick, Mass). No difficulty was experienced with the introduction of the delivery catheter, despite extreme angulation in the aneurysm. An acute episode of hypotension prompted an aortogram to be performed. Extravasation of contrast outside the aneurysm sac was demonstrated. The balloon on the delivery catheter was immediately advanced to the suprarenal aorta and inflated. hypotension was reversed, and hemodynamic stability was restored, thus enabling deployment of the prosthesis to proceed and the repair to be completed by means of the endoluminal method. RESULTS: The patient's blood pressure remained stable after deflation of the balloon, allowing a postprocedure aortogram to be performed. Exclusion of the aneurysm sac was demonstrated. Exclusion of the aneurysm sac from the circulation and a large retroperitoneal hematoma were confirmed by means of a postoperative contrast computed tomography scan. convalescence was complicated by acute renal failure, pneumonia, and prolonged ileus. The patient remained well and active at the follow-up examination 6 months after operation. CONCLUSION: Iatrogenic perforation of an AAA during endoluminal repair may be treated by endovascular means and does not necessarily require conversion to open repair, although this may be the safest option.- - - - - - - - - - ranking = 2.3333333333333keywords = aneurysm (Clic here for more details about this article) |
4/86. The advantages of MRI and MRA for diagnosing Behcet's disease and internal jugular vein thrombosis.Behcet's disease is a multisystem disorder characterized by recurrent aphtous ulcers of mucosal membranes, skin lesions, and vasculitis. The prevalence of vascular involvement is about 25% and this is the leading cause of death in Behcet's disease. Jugular vein involvement is an unusual manifestation of Behcet's disease. Medical insertion of needles into veins or arteries can induce thrombosis or aneurysms. Thus, diagnostic studies or therapy can aggravate the disease and even be fatal. We report a patient with Behcet's disease and rare internal jugular vein thrombosis. We also demonstrate the ability of noninvasive magnetic resonance imaging and magnetic resonance angiography to aid in the diagnosis and evaluation of vascular involvement in Behcet's disease, without risking iatrogenic complications.- - - - - - - - - - ranking = 0.16666666666667keywords = aneurysm (Clic here for more details about this article) |
5/86. Coil embolization of intradural pseudoaneurysms caused by arterial injury during surgery: report of two cases.Intradural pseudoaneurysms arose in two patients as a result of arterial injury incurred during surgery. In the first patient, the pseudoaneurysm developed in the middle cerebral artery, at the site of vessel perforation during aneurysmal surgery. In the second patient, the pseudoaneurysm developed in the anterior communicating artery after removal of a tuberculum sellae meningioma. These aneurysms had small ostia and were successfully embolized with electrolytically detachable coils. The clinical features and the treatment of intracranial pseudoaneurysms are discussed.- - - - - - - - - - ranking = 93.107331453271keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/86. Percutaneous stenting of an latrogenic superior mesenteric artery dissection complicating suprarenal aortic aneurysm repair.PURPOSE: To report endovascular repair of an iatrogenic superior mesenteric artery (SMA) dissection caused by a balloon occlusion catheter. CASE REPORT: A 68-year-old man with a suprarenal aortic aneurysm underwent conventional prosthetic replacement, during which visceral artery back bleeding was controlled with balloon occlusion catheters. Six hours postoperatively, the patient experienced an episode of bloody diarrhea with abdominal pain and tenderness and mild metabolic acidosis. colonoscopy revealed colitis (grade I) without necrosis of the right and left colon. An emergent abdominal computed tomographic scan showed signs of mesenteric ischemia with bowel dilatation and SMA wall hematoma; angiography identified a dissection 1 cm distal to the SMA origin. An Easy Wallstent was deployed percutaneously, successfully reestablishing SMA patency. The postoperative course was uneventful, and the patient remains asymptomatic with a patent SMA stent and aortic graft at 1 year. CONCLUSIONS: latrogenic SMA dissection should be suspected after suprarenal aortic aneurysm repair if signs of mesenteric ischemia arise. Prompt and thorough imaging studies are necessary to confirm the diagnosis and assess the potential for an endoluminal treatment.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
7/86. vertebral artery pseudoaneurysm complicating posterior C1-2 transarticular screw fixation: case report.BACKGROUND: vertebral artery injury during posterior C1-2 transarticular screw fixation occurs in approximately 3% of patients and may remain asymptomatic or result in arteriovenous fistulae, occlusion, narrowing, or dissection of the vertebral artery, and lead to transient ischemic attacks, stroke, or death. CASE DESCRIPTION: This is the first report of a pseudoaneurysm resulting from damage to the vertebral artery during the procedure. This 31-year-old male underwent posterior C1-2 transarticular screw fixation for unstable os odontoideum. Injury to the left vertebral artery occurred while the hole for the left screw was being drilled. Temporary control of bleeding with local pressure was followed by immediate postoperative angiography that revealed a left vertebral artery pseudoaneurysm. Although the patient remained asymptomatic, therapeutic anticoagulation was instituted 6 hours postoperatively. Increasing size of the pseudoaneurysm was noted on routine follow-up angiography 4 weeks later. Endovascular occlusion of the pseudoaneurysm and left vertebral artery, with preservation of vertebrobasilar flow through the right vertebral artery, was accomplished without neurological consequence. CONCLUSIONS: vertebral artery pseudoaneurysm complicating posterior C1-2 transarticular screw fixation may be effectively treated with endovascular approaches.- - - - - - - - - - ranking = 104.37074788493keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/86. Pseudoaneurysm of the lingual artery secondary to tonsillectomy treated with selective embolization.False aneurysm may occur from trauma to the floor of the mouth, including iatrogenic trauma from surgical procedures. This report will present a case of a pseudoaneurysm of the lingual artery following tonsillectomy. Development of lingual artery pseudoaneurysms can occur within a few hours following tonsillectomy. Angiography provides the diagnosis, and endovascular intervention is an efficient alternative to surgery for treatment of such aneurysm with low morbidity. Endovascular embolization with platinum coils is an effective means of controlling bleeding and avoiding surgical intervention.- - - - - - - - - - ranking = 24.193499529984keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/86. An iatrogenic coronary arteriovenous fistula causing a steal phenomenon: an intracoronary Doppler study.We present the case of a 67-year-old man in whom a guidewire broke at rotablation of the right coronary artery, creating an iatrogenic aneurysmal arteriovenous fistula to the coronary sinus. Successful Doppler wire-guided fistula occlusion by percutaneous coil embolization lead to normalization of coronary blood flow and relief of the patient's symptoms. myocardial ischemia in this patient may have been due to a steal phenomenon caused by coronary artery fistulae, as suggested by blood flow velocity data obtained before and after fistula occlusion.- - - - - - - - - - ranking = 0.16666666666667keywords = aneurysm (Clic here for more details about this article) |
