1/484. Vertebral arteriovenous fistula that developed in the same place as a previous ruptured aneurysm: a case report.BACKGROUND: Aneurysms of the extracranial vertebral artery (VA) and vertebral arteriovenous fistulas (VAVFs) are relatively rare diseases. The most frequent cause of both diseases is trauma. Atraumatic lesions are less common. Presented here is a case of atraumatic AVF of the extracranial VA that developed in the same location as a previous ruptured aneurysm of the ipsilateral VA that was originally treated by proximal occlusion 11 years earlier. methods: A 40-year-old woman presented with a massive hematoma in the upper posterior neck region caused by the rupture of an extracranial VA aneurysm. Proximal occlusion of the VA was performed by use of a detachable balloon. She enjoyed good health for 11 years, then she noticed a pulsatile bruit. Angiograms revealed an AVF between the left VA that was fed by collateral circulation and the paravertebral venous plexus. Incidentally found were soft tissue masses in the left retroauricular and the right suboccipital regions. Also, skull X-ray films showed multiple bony defects. biopsy of the subcutaneous mass was performed in the hope of obtaining clues as to which pathological processes had weakened the artery. RESULTS: As direct transarterial access to the fistula was out of the question, the fistulous compartment of the paravertebral venous plexus was tightly packed with multiple platinum coils effected by the transfemoral approach. A histological examination of the specimen revealed features of a neurofibroma, and a diagnosis of neurofibromatosis Type 1 was established. CONCLUSIONS: In this case, transvenous embolization of the VAVF was successfully performed. The fragility of the arterial wall, related to neurofibromatosis Type 1, was considered to contribute to the development of the aneurysm and AVF.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |

3/484. Spinal dural arteriovenous fistula with an associated feeding artery aneurysm: case report.OBJECTIVE AND IMPORTANCE: A case of a spinal dural arteriovenous fistula (DAVF) with two associated feeding artery aneurysms is reported. Intradural spinal arteriovenous malformations have been associated with aneurysms that present with subarachnoid hemorrhage and with venous varices that produce mass effect, but spinal DAVFs have not previously been described in association with feeding artery aneurysms. CLINICAL PRESENTATION: A 71-year-old man presented with progressive spastic paraparesis, constipation, and overflow incontinence. magnetic resonance imaging demonstrated a spinal vascular lesion and venous ischemia in the lower spinal cord. Diagnostic spinal angiography revealed a DAVF originating from the left T11 radicular artery and having the unusual feature of two proximal feeding artery aneurysms. INTERVENTION: The patient deteriorated neurologically after undergoing angiography, prompting emergent surgery. The DAVF was resected through a T11 transpedicular approach. One aneurysm was dolichoectatic and therefore unclippable, requiring proximal occlusion of the parent artery after establishing tolerance of test occlusion using somatosensory evoked potentials; the second aneurysm was adjacent to the fistula and was resected with the DAVF. CONCLUSION: Feeding artery aneurysms in association with spinal DAVFs have not been previously reported. They present additional risk to patients and, with simple modifications of the standard operative approaches, can easily be treated as part of the surgery for the DAVF.- - - - - - - - - - ranking = 1.5714285714286keywords = aneurysm (Clic here for more details about this article) |
4/484. 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 = 0.14285714285714keywords = aneurysm (Clic here for more details about this article) |
5/484. arteriovenous fistula of the thyroid gland associated with spontaneous bleeding from a flow-induced aneurysm of the inferior thyroid artery.A case of acute, spontaneous cervical hemorrhage caused by a ruptured aneurysm of the inferior thyroid artery is described. This lesion was accompanied by an arteriovenous fistula within the thyroid gland that caused a flow-induced aneurysm. diagnosis and treatment were successfully performed by selective angiography with endovascular occlusion and embolization. Both diagnostic and therapeutic management are discussed, and the related literature is reviewed. To our knowledge, this is the first reported case of an aneurysm of a thyroid artery in conjunction with an intraparenchymatous arteriovenous fistula of the thyroid gland.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
6/484. Aortocaval fistula in ruptured aneurysms.OBJECTIVES: to study incidence, clinical presentation and problems in management of aortocaval fistula in our series. DESIGN: retrospective study. MATERIALS: during a seven-year period, 112 patients operated on for abdominal aortic aneurysm, including four patients with aortocaval fistula. methods: standard repair of aortocaval fistula from inside the aneurysmal sac was the preferred operative technique. RESULTS: the incidence of aortocaval fistula was 3.6%. Three cases were found incidentally during emergency surgery for ruptured aneurysms; the fourth case was an isolated aortocaval fistula associated with inferior vena cava thrombosis, diagnosed preoperatively by angiography. In this case, inferior vena cava ligation instead of standard aortocaval repair was performed. CONCLUSIONS: Aortocaval fistulas, although rare, should be kept in mind, because clinical diagnosis is often difficult. Furthermore, unsuspected problems during repair may necessitate appropriate change in operative technique.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |

8/484. arteriovenous fistula after temporomandibular arthroscopy.temporomandibular joint arthroscopy has been associated with various vascular injuries including haemorrhage, pseudoaneurysm and fistula. We describe the endovascular balloon embolization of a traumatic superficial temporal arteriovenous fistula that complicated TMJ arthroscopy. We conclude that suspected vascular injuries after this procedure should be investigated by arteriography, and that embolization is a safe and effective treatment for superficial temporal artery fistulas.- - - - - - - - - - ranking = 0.34520982430818keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/484. Pseudoaneurysm of the superior mesenteric artery with an arteriovenous fistula after simultaneous kidney-pancreas transplantation.Vascular complications remain a significant source of morbidity after pancreatic transplantation. We describe a pseudoaneurysm of the superior mesenteric artery (SMA) with an arteriovenous fistula (AVF) involving the SMA and the superior mesenteric vein (SMV) discovered and treated surgically in the second week after kidney pancreas transplantation. The patient experienced pain over the graft, and subsequent radionuclide and Doppler ultrasound scan were suggestive of a pseudoaneurysm in the head of the pancreas. Awaiting confirmatory angiography, the patient became hypotensive and after resuscitation, underwent emergency surgery when a pseudoaneurysm was found in the head of the pancreas. After looping the proximal and distal recipient iliac artery and base of the donor Y vascular graft, the AVF was separated and ligated. The SMV was dissected off the pancreatic head and repaired over a tamponading intraluminal Foley catheter. Graft function was preserved. Based on this experience, an AVF with or without a pseudoaneurysm in the pancreas allograft should be corrected as soon it is suspected.- - - - - - - - - - ranking = 1.9522678686613keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
10/484. Double layered autogenous vein graft patch reconstruction of the common carotid-internal jugular fistula caused by gunshot wound.Hereby we present a case with a common carotid-internal jugular fistula caused by gunshot wound. The patient was a 32-year old male who had an entrance hole of a bullet on his right anterior cervical area, at the C4 level with a hematoma surrounding it. The exit hole could be detected at the sublingual area. By palpation a thrill and on auscultation a souffle was noted. Neither crepitation, nor any neurologic deficit or any symptom of Horner's syndrome was present. The emergency digital subtraction angiography (DSA) showed a fistulisation to internal jugular vein (IJV) approximately 0.5 cm below the common carotid artery (CCA) bifurcation level. During the operation a hematoma and a false aneurysm was observed on the CCA. Also, proximally to the bifurcation, a communication of CCA with IJV was noted. The wall of the JJV was rather thinned and the size of the vessel had considerably enlarged. Following the evacuation of the hematoma and debridement, the integration of the artery was achieved by placing a double layered autogenous vein graft patch over the 0.5 x 1.5 cm defect. The 0.3 x 1.5 cm defect laterally over the IJV was primarily sutured. The patient was discharged on the fifth day. The control DSA taken on the twelfth day showed a perfect integration of the vessels. We considered the case noticeable due to its rather rare incidence and the double layered autogen vein patch graft reconstruction.- - - - - - - - - - ranking = 0.14285714285714keywords = aneurysm (Clic here for more details about this article) |
