1/262. Diagnostic and therapeutic management of bilateral carotid artery occlusion caused by near-suicidal hanging.In cases of attempted suicide by hanging, a combination of mechanisms causing local destruction of the pharynx, larynx, vessels, and spine, as well as neurologic complications, has to be considered. We present a case of hanging in which a deeply unconscious patient without any palpaple pulsation of the carotid arteries was referred to our otolaryngology department. Computed tomography and angiography showed parapharyngeal air, complete obstruction of both common carotid arteries, and a compensatory circulation through the vertebral arteries. Three hours after the trauma, surgical exploration with resection of the enrolled intima of both carotid arteries and repair of the pharynx was performed. The patient awoke with an infarct of the right hemisphere with incomplete left hemiparesis the next day, but symptoms slowly declined during the following months, and the patient learned swallowing again perfectly. We conclude from our experience that in near-hanged patients a prompt onset of adequate diagnostic and therapeutic measures is mandatory, as good neurologic and functional results may occur even in cases with coma and severe destruction of the carotid arteries and pharyngeal and laryngeal structures. Surgical repair of blunt carotid lesions is recommended and may be crucial for a good outcome.- - - - - - - - - - ranking = 1keywords = trauma (Clic here for more details about this article) |
2/262. Seat-belt-related injuries to the supra-aortic arteries.Five seat-belt-related injuries occurring in four adults are reported. One injury involved the common carotid artery, two the internal carotid and two the subclavian arteries. Three of the four injured persons were asymptomatic and one had delayed-onset symptoms; none suffered stroke. There was no operative mortality or morbidity. overall, the functional results of arterial reconstruction were good, with satisfactory patency at follow-up averaging 15 months.- - - - - - - - - - ranking = 170.11169917558keywords = injury (Clic here for more details about this article) |
3/262. Traumatic dissection of the common carotid artery after blunt injury to the neck.BACKGROUND: Occlusive lesions of the common carotid artery (CCA) resulting from blunt injury are extremely rare, and their clinicopathologic and therapeutic features have not yet been clarified. OBJECTIVES AND RESULTS: Five patients with occlusive lesions of the CCA developed neurologic deficits at 1.5 hours to 10 years after blunt neck injury. Lesions included two complete occlusions, one severe stenosis, and two segmental intimal dissections of the CCA. In the two patients with CCA occlusion, bypass surgery was performed using a Dacron graft between the ipsilateral subclavian artery and the carotid bifurcation. In the remaining three patients, the involved segments were replaced with a Dacron graft. Surgical specimens from the early posttraumatic period revealed intimal tears with mural thrombosis and/or subintimal hematomas and those from the later period showed myointimal hyperplasia or fibrotic organization. CONCLUSION: Traumatic occlusive lesions of the CCA tend to evolve from intimal dissections to severe stenoses or occlusion, compromising cerebral circulation. The involved CCA can be diagnosed early by B-mode Doppler sonography and successfully reconstructed using a Dacron graft.- - - - - - - - - - ranking = 1021.6701950535keywords = injury, trauma (Clic here for more details about this article) |
4/262. 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 = 5keywords = trauma (Clic here for more details about this article) |
5/262. 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 = 850.5584958779keywords = injury (Clic here for more details about this article) |
6/262. Carotid artery-sygmoid sinus fistula: a rare complication of gunshot wound on the base of the cranium.Vascular lesions without clinical manifestation may occur in cranial-facial wounds produced by bullets that course the base of the cranium. This work describes a rare kind of vascular complication in cranial-facial gunshot wound. The authors present the case of a patient, the victim of a cranium-maxillary gunshot wound. Carotid angiography revealed a carotid-sygmoid sinus fistula that filled the sygmoid and transverse sinuses, concomitant to the arterial angiographic phase. A direct communication between the external carotid artery and the sygmoid sinus was disclosed. We are not aware of any other description of this vascular complication in cranial gunshot wound. It is important to recognize this kind of complication in cases of cranial-facial gunshot wound, because new factors harmful to the brain perfusion systems are introduced, in addition to the alterations to venous return and intracranial pressure, caused by the primary trauma. The new non-invasive vascular diagnostic methods are proving useful in filling the gap left by arteriography, which is no longer used in these cases.- - - - - - - - - - ranking = 1.1877494656576keywords = trauma, brain (Clic here for more details about this article) |

8/262. Complex traumatic dissection of right vertebral and bilateral carotid arteries: a case report and literature review.A 27-year-old female motorcycle passenger was admitted with bruises and concussion after a motor-vehicle accident. After a lucid interval of several hours she became stuporous and progressed to an acute comatose state. Computed tomography demonstrated extensive cerebral ischaemia in the territory of the right middle cerebral artery. Angiography after transfer to the authors' hospital revealed dissections of both carotid arteries and of the right vertebral artery. The patient underwent surgical reconstruction of the left internal carotid artery with saphenous vein. The management of this patient is discussed and the literature reviewed.- - - - - - - - - - ranking = 4keywords = trauma (Clic here for more details about this article) |
9/262. Traumatic carotid artery dissection causing blindness.A case of delayed postoperative visual loss due to bilateral traumatic carotid artery dissection is presented. In patients with a major craniofacial injury due to a high-speed motor vehicle accident, we suggest that carotid artery duplex ultrasonography be used in the initial evaluation for possible carotid artery dissection. magnetic resonance imaging of the head and neck with magnetic resonance angiography should be performed subsequently if indicated. early diagnosis and initiation of therapy can minimize complications.- - - - - - - - - - ranking = 171.11169917558keywords = injury, trauma (Clic here for more details about this article) |
10/262. Blunt carotid artery injury after accidental neck compression: report of a case.Almost all cases of carotid artery injury are precipitated by a high-energy impact such as motor vehicle accidents or gunshot wounds, and are usually diagnosed using angiography. We report herein a case of carotid artery injury induced by a low-energy insult with rare clinical signs which was diagnosed using ultrasonography as well as angiography. A 37-year-old man sustained an accidental compression of the neck and was transferred to our emergency room. Horner's syndrome and phrenic nerve palsy were detected on the left side. ultrasonography demonstrated two sites of injury with an intimal flap of the distal left common carotid artery as well as angiography. The patient was placed on anticoagulants and was discharged on the 10th hospital day with both Horner's syndrome and phrenic nerve palsy. This case suggests that surgeons should investigate any possible carotid artery injury, even after low-velocity injuries such as compression of the neck, and therefore an ultrasonic examination should be performed at the initial evaluation and at follow-up studies. In addition, further investigations are also called for to investigate the utility of anticoagulation in the treatment of carotid artery injury.- - - - - - - - - - ranking = 1531.0052925802keywords = injury (Clic here for more details about this article) |
