Purpose: To report several cases illustrating the feasibility and mid-term efficacy of deploying a self-expanding stent-graft to treat traumatic ruptures, pseudoaneurysms, and a spontaneous dissection of the internal carotid artery (ICA). Case Reports: One patient suffered a stab wound and another developed a large pseudoaneurysm years after a gunshot to the neck. The third patient presented with a spontaneous rupture in the setting of fibromuscular dysplasia, and the final patient developed a pseudoaneurysm following carotid endarterectomy in an irradiated neck. All 4 patients were successfully treated with Wallgrafts deployed in the ICA using either an open carotid (first 3 cases) or percutaneous approach (fourth patient). There were no adverse neurological events. During a mean 16-month follow-up (range 6–24), duplex ultrasound and CT scanning found no evidence of restenosis, occlusion, or persistent perfusion of the pseudoaneurysm, which was noted to decrease in all cases. Conclusions: The thin-walled fabric of the Wallgraft appears capable of completely excluding the pseudoaneurysm, resulting in decreased aneurysm size overtime.

Introduction The treatment of aneurysms in the internal carotid bifurcation region (ICABR), including aneurysms of the true internal carotid artery (ICA) terminus, those inclined on the proximal A1 or M1 segments or at the most distal pre-bifurcation (ICA) segment, is often challenging in microsurgical clipping and endovascular surgery. Few reports had discussed flow diversion as a therapeutic option for this group. Methods This was a retrospective study analysing flow diversion in treating ICABR aneurysms. Seven patients harbouring eight aneurysms in the ICABR were treated with flow diversion. Five aneurysms were inclined on the proximal A1 segment, and three were located at the most distal pre-bifurcation segment. Patients’ demographics, presentation, procedure technical description, angiographic and clinical follow-up were recorded. PubMed and Ovid MEDLINE were also reviewed for articles published in English, including case series or case reports, for ICABR aneurysms treated with flow diverters. Results All patients except one underwent angiographic follow-up. The Karman–Byrne occlusion scale was used to determine the occlusion rate. All six patients with documented angiographic follow-up had a class IV occlusion score. No permanent or transient neurological or non-neurological complications were encountered in this study. Conclusion Treating ICABR aneurysms using flow diversion is feasible, with a promising angiographic occlusion rate. Further studies are needed to analyse long-term clinical and angiographic results.

Abstract The natural course of fibromuscular dysplasia (FMD) of the internal carotid artery (ICA). a stenosing angiopathy associated with cerebrovascular insufficiency, has not been described. A search of medical records located 16 female patients with angiographically demonstrated FMD of the ICA. The identical twin of 1 patient was included in the registry on the basis of noninvasive studies consistent with FMD of the ICA. The mean age at diagnosis was 58 years. Follow-up examinations were performed an average of 3.8 years after diagnosis (range, 1 to 9 years); the evaluation included clinical, angiographic, and Doppler studies. Fifteen patients showed no evidence of progression of FMD, whereas 2 patients with coincident atherosclerotic disease had suffered strokes. One patient had undergone surgical dilatation of the ICA. 3 had received oral anticoagulants, and 13 had received either aspirin or no specific therapy. In light of the apparently benign clinical course of uncomplicated FMD of the ICA, it is concluded that dilatation is rarely warranted.

Cervical Internal Carotid Artery

This case illustrates the usefulness of an endovascular stent to treat a pseudoaneurysm of the cervical internal carotid artery. A 46-year-old male patient presented with a spontaneous dissection of the cervical internal carotid artery. After failing conservative therapy, he was treated by endovascular placement of a Palmaz stent at level of the pseudoaneurysm and dissection. Immediate obliteration of pseudoaneurysm was achieved, and patency of the internal carotid artery was maintained. The patient sustained no neurological complications and the stenosis of treated carotid artery did not occur during the 6-month follow-up period. For internal carotid artery dissection, stent placement seems to be a reasonable therapeutic alternative to direct surgery.

Mobilization of a tortuous carotid artery during endarterectomy may produce redundancy of the carotid artery, and kinking. We reviewed our experience with common carotid artery (CCA) imbrication as a technique to shorten the common and internal carotid artery postendarterectomy and to avoid carotid kinking. A retrospective chart review of 163 patients who underwent carotid endarterectomy by the same surgeon between August 1998 and February 2006 was performed. All patients underwent conventional endarterectomy via a longitudinal arteriotomy with an indwelling shunt and patch angioplasty. Patients undergoing concomitant carotid artery imbrication were identified. Twelve patients who underwent carotid imbrication were identified. The mean age was 74.9 ± 8.8 years. Nine patients underwent imbrication of the CCA, and in three cases, the internal carotid artery was plicated. Follow-up duplex ultrasound examinations were available for 10 individuals and mean follow-up time was 10.7 months (range, 1–58 months). There were no cases of peri- or postoperative cerebral accidents and there was no case of restenosis. CCA imbrication as an adjunct to carotid endarterectomy is a feasible technique in preventing postoperative carotid kinking.

Internal carotid artery (ICA) dissection is an important cause of stroke in the younger population. Carotid stenting with or without angioplasty is usually the preferred treatment for symptomatic patients who have failed medical therapy. We report a case of a symptomatic internal carotid artery dissection at the petrous segment of the ICA initially treated conservatively with anticoagulation and antiplatlet agents. Due to early clinical deterioration from near complete carotid occlusion without adequate cross over flow, the patient underwent emergency stenting of the ICA. Post procedure angiography demonstrated no residual stenosis of the ICA. The patient progressively improved and at six months follow-up, the patient had no further symptoms, a normal neurological examination and improvement in the imaging findings. The successful clinical result in our case of ICA stenting for dissection as a ‘hemispheric rescue’ contributes to the growing literature of endovascular management of carotid dissection. The excellent mid term follow-up confirms the efficacy of this treatment for a dominant ICA.

Distal Internal Carotid Artery

Purpose The diagnosis of carotid artery fibromuscular dysplasia is usually made with conventional angiography performed to evaluate a suspected carotid stenosis. The ultrasound findings with fibromuscular dysplasia have not been well described. This study was performed to assess the characteristics of carotid artery fibromuscular dysplasia with duplex ultrasonography. Methods The hospital records for all patients who had carotid duplex ultrasonography were reviewed from January 2000 to October 2003. Patients with findings suspicious for fibromuscular dysplasia formed the basis of this study. The patient demographics, their presenting symptoms, and ultrasound findings were analyzed. Results Carotid duplex studies were performed on 9157 patients during the study period. The presumptive diagnosis of fibromuscular dysplasia was made in 13 female patients (1.2%), with a mean age of 67 ± 10 years (range, 52-79 years). Patients were referred for asymptomatic carotid bruits ( n = 10, 77%) or transient ischemic attack ( n = 3, 23%). Both mid and distal internal carotid artery involvement were seen in five patients (38%), whereas eight patients (62%) had disease isolated to the distal internal carotid artery. Bilateral carotid artery involvement occurred in eight patients (62%). A consistent finding in all patients was multiple areas of alternating focal thickening with thin, dilated arterial walls. Other sonographic findings included velocity increases (mean, 181 cm/sec; range, 135-318 cm/sec), color flow disturbance, and scarcity of plaque in the suspected arterial segment. Magnetic resonance angiography or carotid angiography was performed on seven (54%) patients, confirming the ultrasound diagnoses. One symptomatic patient was successfully treated with open graduated endoluminal dilatation. One patient with asymptomatic carotid bruit underwent carotid stent placement for rapid progression of the disease. No disease progression was seen on follow-up duplex examination in the remaining group, and no patient became symptomatic. Conclusions Fibromuscular dysplasia should be suspected in female patients with high-grade mid to distal carotid artery stenosis without significant atherosclerotic disease. This study demonstrates the usefulness of duplex ultrasound as both a screening test and diagnostic examination for carotid artery fibromuscular dysplasia. Follow-up is warranted in these patients.

Abstract Isolated dissection of the internal carotid artery (ICA) is rare in young patients and is a cause for strong suspicion of fibromuscular dysplasia (FMD), especially when associated with artery elongation and tortuosity. The natural history of cerebrovascular FMD is unknown and management of symptomatic patients can be challenging. We report the case of a 44-year-old female patient with a history of transient ischemic attack in the absence of cardiovascular risk factors, associated with an isolated left ICA dissection and kinking. Carotid duplex ultrasound confirmed the diagnosis of dissection and demonstrated severe stenosis of the left ICA. The patient underwent surgical repair and histopathological evaluation confirmed the diagnosis of FMD with dissection. An autogenous great saphenous vein bypass was performed and the patient had an uneventful recovery. Cervical carotid artery dissection can be related to underlying arterial pathologies such as FMD, and the presence of ICA tortuosity highlights certain peculiarities for optimal management, which might be surgical.
