Giant Carotid Pseudoaneurysm
نویسندگان
چکیده
A 59-year-old woman presented with a pulsatile lump in the neck after carotid artery stenting for symptomatic focal stenosis (50–69%) of the left carotid bulb (Fig. 1A). Cervical duplex ultrasonography and computed tomography-angiography revealed a large lobulated pseudoaneurysm (measuring 2.6 × 2.4 × 2.1 cm) involving the left common and internal carotid artery (Fig. 1B and C). Swirling motion of blood flow, referred to as the “yin-yang sign”, was observed within the pseudoaneurysm (Supplementary movie 1). During surgical exploration, the tissue surrounding the pseudoaneurysm was noted be infected involving left internal carotid artery, vagus nerve and the internal jugular vein (Fig. 1D).

Endovascular repair of giant traumatic pseudo-aneurysm of the common carotid artery.
BACKGROUND Delayed presentation of carotid artery pseudoaneurysm following many years after self-inflicted penetrating injury of the neck is extremely rare. Open surgical carotid repair may involve sternotomy for proximal vascular control. Endovascular treatment is evolving as a less-invasive treatment option. METHODS We report a 55-year-old man with a history of paranoid schizophrenia who pr...
متن کاملTelescoping Dual Covered Stent Graft Construct for Endovascular Treatment of a Giant Extracranial Carotid Artery Pseudoaneurysm
Large pseudoaneurysms which compress the parent vessel are challenging lesions to successfully treat with endovascular therapy. We describe the endovascular treatment of a giant extracranial carotid artery (ECCA) pseudoaneurysm resulting in substantial mass effect on the common carotid artery (CCA) bifurcation using a telescoping dual covered stent graft construct. A 56-year-old male was diagno...
متن کاملEndovascular treatment of epistaxis in a patient with tuberculosis and a giant petrous carotid pseudoaneurysm.
A 31-year-old man with pulmonary tuberculosis who did not have human immunodeficiency virus had massive epistaxis from a giant petrous internal carotid artery pseudoaneurysm. Endovascular trapping of the aneurysm was performed, curing the epistaxis. MR showed multiple enhancing brain lesions that resolved with additional antituberculous drug therapy.
متن کاملPseudoaneurysm of the Common Carotid Artery in an Infant due to Swallowed Fish Bone
Carotid artery pseudoaneurysm is a rare condition, particularly in the paediatric population. Only about 30 cases of carotid artery aneurysms in infants have been published until now. This paper reports the case of a giant pseudoaneurysm of the left common carotid artery due to swallowed fish bone by an 8-year-old boy. This pseudoaneurysm was 5.5 cm transverse-diameter and resulted in severe re...
متن کاملVariant of Persistent Primitive Trigeminal Artery Associated with Giant Internal Carotid Artery Pseudoaneurysm
We report a rare variation of the left persistent primitive trigeminal artery with direct anastomosis with the ipsilateral posterior cerebral artery in a 53-year-old women. She was sent to the hospital with visual deterioration and consciousness disturbance (Glasgow coma scale = E4V3M5). Marked hydrocephalus was found. An associated giant pseudoaneurysm was shown arising from the cisternal segm...
