1/101. 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 = 1keywords = aneurysm (Clic here for more details about this article) |
2/101. Post-traumatic dissecting aneurysm of extracranial internal carotid artery: endovascular treatment with stenting.Traumatic internal carotid dissection occurs frequently in motor vehicle accidents, typically extracranially, close to the skull base. dissection may lead to stenosis or occlusion of the vessel, possibly with a pseudoaneurysm, symptoms ranging from neck pain to neurological deficits. In symptomatic patients and in cases of pseudoaneurysm, when conservative medical treatment fails, surgery or endovascular treatment are indicated. We report a post-traumatic dissecting aneurysm of the extracranial internal carotid artery successfully treated with stenting via a transfemoral approach.- - - - - - - - - - ranking = 75.345274835825keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/101. Pseudoaneurysm of the internal carotid artery after shrapnel injury in World war II: demonstration by CT angiography with 3D MIP reconstruction.A case of pseudoaneurysm of the left internal carotid artery (ICA) after shrapnel injury is demonstrated by intra-arterial digital subtraction angiography (DSA) and computed tomography angiography (CTA) with subtraction technique. Although the pseudoaneurysm was well demonstrated by intra-arterial DSA, CTA was the only modality to demonstrate the three-dimensional shape of the perfused part of pseudoaneurysm and the aneurysmal neck, which affected the therapeutic strategy. The CTA technique is useful in the assessment of large pseudoaneurysms and for therapeutic planning.- - - - - - - - - - ranking = 145.69054967165keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/101. Remote vascular catastrophes after neurovascular interventional therapy for type 4 ehlers-danlos syndrome.Type 4 ehlers-danlos syndrome (EDS 4) is the most malignant form of ehlers-danlos syndrome, often accompanied by neurovasacular complications secondary to vessel dissection or aneurysms. The fragile nature of connective tissue in these patients makes exovascular and endovascular treatment hazardous. We have treated four patients with EDS 4 over the last 8 years by using neuroendovascular procedures. Two of these individuals suffered remote vascular injuries around the time of their procedures and ultimately died. The circumstances surrounding their deaths will make up the body of this report.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
5/101. Delayed epistaxis resulting from external carotid artery injury requiring embolization: a rare complication of transsphenoidal surgery: case report.OBJECTIVE AND IMPORTANCE: Delayed epistaxis resulting from trauma to branches of the external carotid artery is an infrequent but potentially serious complication of transsphenoidal surgery. We report two cases of severe, delayed epistaxis in patients who had undergone transsphenoidal surgery. In both cases, noninvasive treatment failed, necessitating endovascular intervention. CLINICAL PRESENTATION: The first patient, a 52-year-old woman with a prolactinoma, underwent a second transsphenoidal resection 18 months after the first surgery. She was readmitted on postoperative Day 15 with massive epistaxis. The second patient, a 40-year-old woman, had undergone two transsphenoidal surgeries, 14 years apart, for an adrenocorticotropic hormone-secreting adenoma. She was readmitted with massive epistaxis on postoperative Day 17. INTERVENTION: Both patients were initially treated with nasal balloon packing but experienced recurrent hemorrhage when the balloon was deflated, necessitating referral to the interventional radiology department for embolization. At arteriography, the first patient was found to have a pseudoaneurysm of the medial branch of the left internal maxillary artery, which was subsequently embolized. Arteriography in the second patient revealed an abnormally dilated midline branch of the right internal maxillary artery in the nasal septum; this vessel was occluded at arteriography. CONCLUSION: Delayed massive epistaxis is a rare but significant complication of transsphenoidal surgery. Injury to branches of the external carotid artery, along with injury to the internal carotid artery, should be suspected in patients who present with delayed epistaxis after transsphenoidal surgery. angiography performed in patients with refractory bleeding should include selective external carotid injections. epistaxis that is refractory to anterior and posterior nasal packing may be effectively treated with endovascular embolization.- - - - - - - - - - ranking = 35.172637417912keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/101. Bilateral traumatic caroticocavernous fistulae: total resolution following unilateral occlusion.balloon occlusion is the accepted treatment for direct posttraumatic caroticocavernous fistula. We present a case of bilateral traumatic fistulae associated with a pseudoaneurysm. Resolution of both fistulae occurred following treatment of one of them by balloon occlusion of the internal carotid artery. This case highlights the importance of considering a more conservative approach to bilateral fistulae or those associated with a pseudoaneurysm. We review other treatment options.- - - - - - - - - - ranking = 70.345274835825keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
7/101. Traumatic brachiocephalic pseudoaneurysm presenting with delayed stroke: case report.We report a traumatic pseudoaneurysm of the internal carotid artery bifurcation and subclavian artery with recurrent strokes events in a 19-year-old man. He was admitted with an acute left hemiparesis. His history revealed a similar episode 1 year and a major car accident 3 years previously. Contrast enhanced MR angiography confirmed colour Doppler sonographic findings of a carotid and subclavian artery pseudoaneurysm presumably resulting from seat-belt trauma. The pseudoaneurysm, containing thrombus, was thought to be the source of artery-to-artery embolism.- - - - - - - - - - ranking = 246.20846192539keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/101. aneurysm of the internal carotid artery following soft tissue penetration injury.Aneurysms of the extracranial arteries are in most cases secondary to atherosclerosis but may also be due to degeneration, congenital abnormalities, trauma or unclear etiology. They present either with bulging in the lateral pharyngeal wall or the neck. Therefore, otolaryngologists are often among the first physicians to see the patient. In this report, we present a case of spontaneous oral bleeding that was caused by a pseudoaneurysm following 2 weeks after a soft tissue penetration injury in a child. The facial swelling of the child was initially diagnosed to be mumps by its pediatrician and the fever treated with aspirin. A pseudonaneurysm of the internal carotid artery was identified by arteriography as the source of the abrupt oral bleeding and required immediate surgical treatment including radiological means. Our report should illustrate the importance of careful preoperative evaluation as well as a high index of suspicion especially in children, where evaluation of history is difficult.- - - - - - - - - - ranking = 36.172637417912keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/101. Treatment of internal carotid artery dissections with endovascular stent placement: report of two cases.Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma-related extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpetrosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
10/101. Pseudoaneurysm of the internal carotid artery: treatment with a covered stent.dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable.- - - - - - - - - - ranking = 74.345274835825keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
