1/19. Endovascular occlusion of a carotid pseudoaneurysm complicating deep neck space infection in a child. Case report.Pseudoaneurysm formation of the cervical internal carotid artery (ICA) is a rare, potentially lethal complication of deep neck space infection. This entity typically occurs following otolaryngological or upper respiratory tract infection. The pseudoaneurysm is heralded by a pulsatile neck mass, Homer's syndrome, lower cranial neuropathies, and/or hemorrhage that may be massive. The recommended treatment includes prompt arterial ligation. The authors present a case of pseudoaneurysm of the cervical ICA complicating a deep neck space infection. A parapharyngeal staphylococcus aureus abscess developed in a previously healthy 6-year-old girl after she experienced pharyngitis. The abscess was drained via an intraoral approach. On postoperative Day 3, the patient developed a pulsatile neck mass, lethargy, ipsilateral Horner's syndrome, and hemoptysis, which resulted in hemorrhagic shock. Treatment included emergency endovascular occlusion of the cervical ICA and postembolization antibiotic treatment for 6 weeks. The patient has made an uneventful recovery as of her 18-month follow-up evaluation. Conclusions drawn.from this experience and a review of the literature include the following: 1) mycotic pseudoaneurysms of the carotid arteries have a typical clinical presentation that should enable timely recognition; 2) these lesions occur more commonly in children than in adults; 3) angiography with a view to performing endovascular occlusion should be undertaken promptly; and 4) endovascular occlusion of the pseudoaneurysm is a viable treatment option.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/19. MR diagnosis of a congenital abnormality of the thoracic aorta with an aneurysm of the right subclavian artery presenting as a Horner's syndrome in an adult.Congenital abnormality of the aortic arch is a diagnosis made most of the time incidentally in childhood, unless dysphagia or respiratory disorders occur before. A case of a complex aortic arch anomaly with an aneurysm of the right subclavian artery presenting as an isolated Horner's syndrome in an adult is reported herein. magnetic resonance imaging led to this very unusual diagnosis.- - - - - - - - - - ranking = 0.059531810482072keywords = aneurysm (Clic here for more details about this article) |
3/19. Horner's syndrome after carotid artery stenting: case report.BACKGROUND: angioplasty and stenting of various lesions of the carotid artery is gaining in popularity. Our knowledge of the efficacy and limitations of this promising technology is incomplete. Although Horner's syndrome and its variants have been described after traumatic, spontaneous, or surgical carotid dissection, it has not been reported after carotid artery stenting. CASE DESCRIPTION: A 36-year-old woman presented with left neck and ear pain and a 3-year history of rushing noises in her left ear. angiography demonstrated evidence of dissection of the left internal carotid artery at the skull base with a pseudoaneurysm.The pseudoaneurysm was treated with a 6-mm diameter self-expanding stent in a 4-mm diameter left internal carotid artery. A few hours later, she developed partial Horner's syndrome with a subtle ipsilateral ptosis and miosis without anhidrosis. angiography performed on the next day did not demonstrate further dissection or aneurysm growth but did show distention of the artery wall because of the stent. She did not develop any further sequelae. CONCLUSION: This case suggests that stretching of the artery wall may result in stretching of surrounding structures. The sympathetic fibers surrounding the internal carotid artery are clearly sensitive to this degree of stretch. Possible complications associated with stretch injury must be considered when choosing the stent diameter.- - - - - - - - - - ranking = 0.25892977157231keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/19. Horner's syndrome resulting from agenesis of the internal carotid artery: report of a third case.INTRODUCTION: Only two previous reports of agenesis of the internal carotid artery with a coexistent Horner's syndrome are to be found in the medical literature. CASE REPORT: We report a case of a male child seen initially for what was presumed to be a traumatic superficial temporal artery aneurysm. MRA incidentally revealed ipsilateral agenesis of the internal carotid artery. This child's physical exam included ipsilateral Horner's syndrome. CONCLUSION: This case report illustrates that agenesis of the internal carotid artery does indeed cause Horner's syndrome in some cases. The clinician who diagnoses a patient with Horner's syndrome should remember that agenesis of the internal carotid artery may be the cause as this entity can be associated in itself with other pathologies of the central nervous system.- - - - - - - - - - ranking = 0.011906362096414keywords = aneurysm (Clic here for more details about this article) |
5/19. Purtscher-like retinopathy and Horner's syndrome following coil embolization of an intracavernous carotid artery aneurysm.BACKGROUND: Coil embolization is a non-invasive method for treating intracranial vascular malformations by inducing thrombus formation. It is particularly useful in management of cerebral aneurysms and avoids the risks associated with surgical clipping. Occasionally, embolic complications occur which result in transient or permanent loss of vision. methods: Case report of a 29-year-old Caucasian woman who underwent coil embolization and balloon occlusion of an intracavernous carotid aneurysm. Shortly thereafter she described visual changes and a droopy eyelid. RESULTS: Examination revealed pupillary miosis and mild ptosis of the right upper lid. Perimetry showed an arcuate scotoma superiorly and an inferonasal step in the right eye. Fundus examination revealed multiple cotton-wool spots along the peripapillary area and along the temporal vascular arcades reminiscent of Purtscher retinopathy. After 4 weeks, she had marked improvement in her visual symptoms. Most of the cotton-wool spots had resolved and the visual field had normalized. However, the ptosis and anisocoria remained unchanged. CONCLUSIONS: Coil embolization is a non-invasive method for treating carotid aneurysms. However, it carries the risk of ophthalmic events, warranting baseline ophthalmic examinations prior to such intervention.- - - - - - - - - - ranking = 0.0833445346749keywords = aneurysm (Clic here for more details about this article) |
6/19. Rare cause of Horner's syndrome: pseudoaneurysm of right subclavian artery in an intravenous drug user.Pseudoaneurysms of the subclavian artery are extremely rare lesions despite the overall increase in the frequency of septic pseudoaneurysms caused by illicit parenteral drug abuse. A case of subclavian artery pseudoaneurysm presenting with Horner's syndrome in an intravenous drug user is discussed.- - - - - - - - - - ranking = 0.7529765905241keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
7/19. Traumatic pseudoaneurysm of the internal carotid artery presenting with oculosympathetic palsy.BACKGROUND: Blunt internal carotid artery (ICA) injury is rare but undiagnosed can have disastrous clinical consequences. AIM: To report a late presentation of blunt ICA injury in a young male following a road traffic accident. RESULT: A 16-year-old male presented 11 days following a head injury with a unilateral Horner's syndrome. Imaging confirmed a pseudoaneurysm of the ICA. The patient was treated with anticoagulant therapy. CONCLUSION: diagnosis of ICA injury requires a high index of suspicion and presentation with unusual neurological signs following blunt trauma to the head and neck requires prompt investigation.- - - - - - - - - - ranking = 0.61755852368974keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/19. Stridor and Horner's syndrome, weeks after attempted right subclavian vein cannulation.A 23-year-old woman presented with renal failure resulting from polycystic kidney disease (PKD) aggravated by tubulo-interstitial nephritis. Emergency haemodialysis was planned, and cannulation of the right subclavian vein was attempted, but failed. During this procedure, inadvertent arterial puncture occurred. Transient mild ischaemia of the right arm, and a transient Horner's syndrome were noted. Seven weeks later she presented with severe stridor with impending respiratory failure necessitating emergency intubation; the right-sided Horner's syndrome had recurred. CT imaging showed a large pseudo-aneurysm of the brachiocephalic artery resulting in severe compression of the trachea. Using a prosthetic graft, the operation for the pseudo-aneurysm was successful; there were mild neurological sequelae. Although her family history was negative, autosomal dominant PKD should be considered, and we discuss the possible role of a pre-existing PKD-associated aneurysm.- - - - - - - - - - ranking = 0.035719086289243keywords = aneurysm (Clic here for more details about this article) |
