Extracranial carotid artery aneurysms are uncommon and not much is known about them. The purpose of this study is to report the authors’ surgical experience and present a review of this entity. This single institution experience shows that resection of these aneurysms and restoration of flow can be accomplished using a number of surgical techniques with relatively low morbidity and mortality. Endovascular techniques are also increasingly being considered in the repair of these aneurysms, although long‐term data from such techniques are not currently available. 相似文献

Between 1982 and 1991 we performed eight operations on seven patients with carotid artery aneurysms. Their mean age was 52.8 years (range: 20–67 years). Five aneurysms were atherosclerotic, one was associated with Marfan's syndrome, and two were pseudoaneurysms, one occurring after Dacron patch angioplasty and the other due to tuberculosis. Seven aneurysms were treated electively; one patient underwent an emergency surgical procedure. In one case, the internal carotid artery was ligated. Seven operations were reconstructive. No intraluminal shunt was used. No perioperative deaths occurred. Regressive hemiparesis and ipsilateral Horner's syndrome developed in one patient. The follow-up period ranged from six months to nine and a half years. One patient died of myocardial infarction three months after surgery. 相似文献

A retrospective review of 42 patients (mean age 61.4 years) with surgically managed symptomatic internal carotid artery occlusion is reported. A standardized surgical protocol aimed at restoration of flow in the vessel was used. Presenting symptoms included hemispheric transient ischemic attacks in 68% of patients, new fixed neurological deficits in 28%, amaurosis fugax in 28%, and stroke-in-evolution in 9%. Twenty-four arteries were successfully reopened. A proximal remnant angioplasty (stumpectomy) was performed alone in nine patients or in combination with an external carotid endarterectomy in nine. In four patients with persisting symptoms who failed to achieve primary restoration of flow, a superficial temporal-to-middle cerebral artery bypass procedure was performed. The permanent surgical morbidity rate was 2% and the surgical mortality rate was 0%. Transient postoperative deficits were present in three patients (7%). Follow-up review at a mean of 40 months was obtained in 39 patients (93%). Following surgical intervention, five patients died of unrelated causes, two had neurological events consistent with a transient cerebral ischemic attack, and two had vertebrobasilar insufficiency. No patient suffered from stroke. Of the 24 successfully reopened vessels, follow-up ultrasound evaluations were obtained in 17 (73%) at a mean of 28 months after surgery. In 15 patients (88%) the vessels were widely patent, one (5.8%) had stenosis greater than 70%, and one (5.8%) showed asymptomatic reocclusion. Reopening occluded internal carotid arteries in selected patients is associated with low surgical morbidity and mortality rates. Further studies are necessary to determine the impact of this surgical therapy on the natural history of this condition. 相似文献

To determine the safest method of treating simultaneously occurring coronary artery disease and asymptomatic carotid stenosis, patients were randomly assigned to either combined operation or a staged procedure with coronary artery surgery done first, followed by carotid endarterectomy. In the initial 70 patients, there were two strokes (5.9%) and two deaths (5.9%) in the combined group and four strokes (11%) and one death (2.8%) in the group with coronary artery surgery performed first. 相似文献

The obstructing thrombus in a totally occluded internal carotid artery may act as a source of cerebral emboli. These emboli traverse the external carotid and ophthalmic arteries and enter the intracranial circulation via retrograde collateral pathways. Surgical treatment can result in complete abatement of symptoms in selected patients. The authors describe internal carotid "stump" syndrome in a 47-year-old man and discuss the options for surgical management. 相似文献

Results, complications, and operative techniques of the surgical management of 20 aneurysms of the distal extracranial internal carotid artery (ICA) in 19 patients are reviewed. The proximity of these aneurysms to the styloid process is not considered as a chance occurrence, and the possibility is raised that these lesions are related to trauma from that structure. False aneurysms from spontaneous dissections are believed to occur only in those dissections that begin distally; they are not found in dissections that begin proximally. Treatment was individualized and dependent upon: 1) the size and location of the aneurysm; 2) symptomatology; and 3) hemodynamic considerations based upon intraoperative cerebral blood flow (CBF) measurements determined from the clearance of xenon-133 injected into the ipsilateral ICA. Methods of treatment included: resection of the the aneurysm with placement of an interposition saphenous vein graft in seven patients; resection of the aneurysm with end-to-end anastomosis of the ICA in five; ICA ligation in three; clipping of the aneurysm in one; and extracranial-to-intracranial bypass in four. One patient sustained a postoperative cerebral ischemic complication from embolization which resulted in a mild permanent impairment in right hand dexterity. There were no other cerebral ischemic complications in the group, largely attributable, it is thought, to the use of intraoperative CBF measurements and continuous electroencephalograms. Four patients had transient dysphagia from traction damage to the pharyngeal and superior laryngeal nerves, and one patient with preoperative difficulty in swallowing required a gastrostomy. Long-term results have been excellent. Use of the operating microscope facilitated the suturing of the distal anastomosis in cases in which the ICA was reconstructed by an interposition vein graft or end-to-end anastomosis. 相似文献

The patient with bilateral internal carotid artery occlusion is at high risk for development of stroke. Medical management and extracranial-intracranial bypass do not appear to offer these patients any protection from symptoms of cerebrovascular insufficiency. Our initial treatment in 11 of 12 patients who had this pattern of extracranial arterial occlusion has been external carotid artery revascularization. Nineteen procedures were performed for symptomatic lesions in all cases except one. There were no perioperative strokes or deaths. During a mean follow-up of 44.7 months, no new strokes occurred. Among 10 patients undergoing external carotid artery revascularization alone, only one transient ischemic attack occurred in follow-up. Seven of the eight surviving patients are presently asymptomatic. External carotid artery revascularization may be an effective and durable treatment for the patient with bilateral internal carotid artery occlusion. 相似文献

Mediastinoscopy is a widely used method to achieve pathologic diagnosis of enlarged lymph nodes or undefined mediastinal solid mass. Aortic arch penetration and injury of the supraaortic arteries are rare but very dangerous complications of mediastinoscopy. We describe the hazardous transportation of a 57-year-old woman after mediastinoscopic injury of the right common carotid artery and its successful repair with cardiopulmonary bypass and deep hypothermia. 相似文献

Fourteen operations were performed in 13 patients with total carotid artery occlusion. All patients had symptoms ranging in duration from a few hours to several months. Flow was reestablished in 10 of the 14 arteries operated on, a success rate of 74 percent. Complications included one operative death and one permanent neurologic deficit. An aggressive approach to the surgical management of patients with total carotid artery occlusion is recommended. 相似文献

Operative repair of extracranial carotid artery aneurysms has been infrequently reported. A unique case is presented in which an aneurysm of the cervical internal carotid artery contained a ball valve thrombus. The patient experienced transient ischemic attacks whenever a position was assumed which permitted occlusion of the internal carotid artery by the free floating thrombus. The aneurysm and thrombus were successfully resected and primary anastomosis of the internal carotid artery carried out to the common carotid artery. The patient has remained free of cerebrovascular ischemic symptoms for 18 months following operative repair. The previously reported surgical experience with extracranial carotid artery aneurysms is reviewed. 相似文献

The hemodynamic significance of the kinked internal carotid artery and cerebrovascular insufficiency are demonstrated. Several procedures have been devised to correct a carotid kink, but these involve resection or excision of the internal, external or common carotid artery. We currently prefer a reimplantation technique whereby preservation of the external carotid is maintained, resection of the internal carotid artery is avoided and, when necessary, endarterectomy may be safely employed. 相似文献

Carotid endarterectomy (CEA) is the main treatment for atherosclerotic plaque of the cervical internal carotid artery. The surgical anatomy of the carotid arteries was studied in the carotid triangle of 49 cadavers. The carotid bifurcation was located at the level of the lower third of C-3. The superior thyroid artery arose from the anterior wall of the external carotid artery in 70% of specimens and from the distal portion of the common carotid artery in 30%. The lingual artery arose as a separate trunk between the origins of the superior thyroid and facial arteries in 81% of specimens, with the facial artery from a common trunk in 18%, and with the superior thyroid artery in 1%. The occipital artery arose from the posterior aspect of the external carotid artery above the level of origin of the facial artery in 57% of specimens, between the origins of the facial and lingual arteries in 32%, and below the origin of the lingual artery in 11%. The origin of the occipital artery was positioned low and the distal portion of the occipital artery was crossed by the hypoglossal nerve in 20%. The ascending pharyngeal artery arose from the posterior wall of the external carotid artery above the level of origin of the lingual artery in 66% of specimens, below the origin of the lingual artery in 9%, from the proximal portion of the occipital artery in 19%, from the carotid bifurcation in 2%, and from the internal carotid artery in 2%. The branches of the external carotid artery are the key landmarks for adequate exposure and appropriate placement of cross-clamps on the carotid arteries. It is necessary to understand the surgical anatomy of the carotid arteries to carry out successful removal of plaque and minimize postoperative complications in a bloodless surgical field. 相似文献

BACKGROUND: Comparison of carotid endarterectomy in patients with and without occluded contralateral carotid artery. METHODS: Design: evaluation of results without using shunt or patch. Setting: Hospital, Medical School, University of Athens. Subjects: 235 patients, divided into group I of 40 patients with and group II of 195 patients without occluded contralateral carotid artery. Intervention: carotid endarterectomy under general anesthesia. Main outcome measures: heparin administration, stable hemodynamic status during clamping, short duration monitoring postoperatively. RESULTS: Postoperative morbidity of both groups was 2.5% (6/235) and mortality 1.7% (4/235). Group I: mortality rate was 2.5% (1/40) major and minor stroke each 2.5% (1/40) and group I: 1.5% (3/195) and 1% (2/195) respectively (NS). Four to 108 months later, 30% (12/40) of group I and 21% (41/195) of group II died. CONCLUSIONS: Endarterectomy of the carotid artery under general anesthesia without use of shunt and patch in patients with or without occlusion of the contralateral carotid artery presented the same comparative results. Candidates for carotid endarterectomy should be screened systematically for coronary disease preoperatively and annual stress testing postoperatively, tactics which may improve early and late mortality rate after carotid surgery. 相似文献

Surgery of the totally occluded internal carotid artery has been controversial since the first case was reported by Fields, Crawford, and DeBakey [2] in 1958. Two cases and a review of the literature are presented to show that complete cerebral angiography should be the determining factor for operating in those patients with symptoms referable to the totally occluded internal carotid artery. 相似文献

Surgical management of acute complications and critical restenosis following carotid artery stenting
Carotid artery angioplasty with stenting (CAS) is being increasingly used in the treatment of extracranial carotid artery
stenosis. As in other catheter-based approaches to the treatment of arterial disease, surgical intervention may be required
because of either acute complications or correct critical restenosis. We have reviewed our experience managing early complications
and critical in-stent restenoses after CAS in a tertiary care university hospital and a Veterans Affairs Medical Center. During
the last 5 years, 22 carotid arteries (21 patients) underwent CAS. One patient developed thrombosis and rupture of the carotid
artery during stenting. Two other patients (3 arteries) developed critical restenosis within 12 months. Subsequent surgical
reconstructions included an internal carotid artery (ICA)–to–external carotid artery (ECA) transposition and a common carotid
artery (CCA)–to–ICA bypass with reversed saphenous vein (RSV). The patient who underwent CCA–to–ICA bypass later required
subclavian–to–ICA bypass because of rapidly progressive intimal hyperplasia and subsequent occlusion of the CCA. The other
patient has not had surgical repair because of his deteriorating condition and significant co-morbidities. During the same
time period, two additional patients were referred from outside institutions specifically for surgical intervention after
carotid stenting. One had delayed rupture of the carotid artery 1 day after stenting and underwent urgent surgical repair.
Another patient had early, critical restenosis within the stent and underwent placement of a CCA–to–ICA interposition graft
using RSV. Acute treatment failures after CAS can be successfully managed using standard surgical techniques. Patients who
develop critical in-stent restenosis requiring surgical repair may need more challenging surgical reconstructions to maintain
cerebral perfusion. 相似文献
