Dissecting Aneurysms

Hemorrhagic intracranial dissecting aneurysms are known to have a poor natural history and an increased tendency to rebleed. The communicating segment of the internal carotid artery (ICA) is an infrequent site of dissection that is difficult to manage using deconstructive endovascular treatment because of the need to preserve important vascular branches. We report two cases of ruptured dissecting aneurysms that occurred in communicating segments of the ICA and treated using a reconstructive endovascular technique involving stent-assisted coiling. Case 1 was a 59-year-old woman who was diagnosed with subarachnoid hemorrhage (SAH). Digital subtraction angiography (DSA) indicated a ruptured dissecting aneurysm that arose from the left communicating segment of the ICA. Stent-assisted coiling was performed and followed by a second overlapping stent technique. No deterioration was observed on DSA after one week of follow-up or on magnetic resonance angiography (MRA) after four months of follow-up. The patient was discharged without neurological complications (Glasgow Outcome Scale 5). Case 2 was a 34-year-old man who was admitted with a diagnosis of SAH. DSA revealed a suspected lesion of a ruptured dissecting aneurysm of the left communicating segment of the ICA. Stent-assisted coiling was performed, and partial occlusion was achieved. No deterioration was observed on DSA after two weeks of follow-up or on MRA after six months of follow-up. The patient was discharged without neurological complications (Glasgow Outcome Scale 5). These cases suggest that using stent-assisted coiling could be a feasible modality for treating ruptured ICA dissecting aneurysms in the communicating segment.

Background Subarachnoid hemorrhage (SAH) secondary to rupture of a blister aneurysm (BA) results in high morbidity and mortality. Endovascular treatment with the pipeline embolization device (PED) has been described as a new treatment strategy for these lesions. We present the first reported case of PED retraction and foreshortening after treatment of a ruptured internal carotid artery (ICA) BA. Case description A middle-aged patient presented with SAH secondary to ICA BA rupture. The patient was treated with telescoping PED placement across the BA. After 5 days from treatment, the patient developed a new SAH due to re-rupture of the BA. Digital subtraction angiography revealed an increase in caliber of the supraclinoid ICA with associated retraction and foreshortening of the PED that resulted in aneurysm uncovering and growth. Conclusions PED should be oversized during ruptured BA treatment to prevent device retraction and aneurysm regrowth. Frequent imaging follow up after BA treatment with PED is warranted to ensure aneurysm occlusion.

Abstract BACKGROUND: Blister aneurysms of the internal carotid artery (ICA) are uncommon. There is a paucity of data on the long-term outcomes of patients. OBJECTIVE: To review our experience with the treatment of these lesions. METHODS: We retrospectively reviewed all aneurysms treated at our institution between 1994 and 2005. Relevant operative notes, radiology reports, and inpatient/outpatient records were reviewed. RESULTS: Seventeen patients (3 male, 14 female) with 18 blister aneurysms of the ICA were identified. The mean age was 44.6 years (range, 17–72; median, 42 years). Twelve patients (70.6%) presented with aneurysmal subarachnoid hemorrhage. The mean admission Glasgow Outcome Scale score was 4.3 (range, 2–5; median, 5). All patients were initially treated using microsurgical technique with direct clipping (n = 15; 83.3%) or clip-wrapping with Gore-Tex (n = 3, 16.7%). There were 4 cases of intraoperative rupture, all associated with attempted direct clipping; all 4 cases were successfully clipped. Two cases rebled post-treatment. Both rebleeding episodes were managed with endovascular stenting. Follow-up angiography was available for 14 patients and revealed a new aneurysm adjacent to the site of clipping in 1 patient and in-stent stenosis in 2. At the mean follow-up of 74.5 months (median, 73; range, 7–165), the mean Glasgow Outcome Scale score was 4.6 (range, 2–5; median, 5). CONCLUSION: Microsurgical treatment of blister aneurysms of the ICA results in excellent outcome. In the evolution of treating these friable aneurysms, we have modified our clip-wrapping technique and use this technique when direct clipping is not feasible.

Abstract OBJECTIVE Endovascular stent reconstruction is the primary intervention for cervical and intracranial dissections in symptomatic patients refractory to medical management. Advancement of traditional balloon-expanding stents into the distal internal carotid artery and vertebrobasilar artery can be technically challenging and potentially traumatic. METHODS On retrospective review, nine patients at our institution with distal cervical and/or intracranial dissections were alternatively treated with the self-expanding, dedicated intracranial Neuroform stent. Three patients with dissecting aneurysms also required stent-assisted coil embolization. Seven patients were followed with imaging and clinical assessment for a mean of 16.3 months. RESULTS All patients (five men, four women; mean age, 50 yr) were symptomatic. Spontaneous (n = 4) or traumatic and/or iatrogenic (n = 5) dissections involved the internal carotid artery (n = 2), vertebral artery (n = 5), and vertebrobasilar artery (n = 2). Indications for treatment included transient ischemic attacks, impending infarcts, antiplatelet failure, enlarging or ruptured dissecting aneurysms, intracranial dissections, or subarachnoid hemorrhages. Dissections were treated with single (n = 4), overlapping (n = 2), or tandem (n = 3) Neuroform stents. Dissection-related mean stenosis improved from 76% preprocedure to 23% postprocedure, with further reduction to 8% at follow-up imaging. Stent-assisted coil embolization of large dissecting aneurysms (n = 3) resulted in retreatment of a neck remnant (n = 1). Small dissecting aneurysms (n = 5) underwent spontaneous stent-induced thrombosis. There were no procedure-related complications. Mortality was limited to the presenting sequelae of vertebrobasilar artery thrombosis (n = 2). Suboptimal technical outcomes were related to delayed in-stent stenosis (n = 2). All surviving patients (n = 7) reported clinical improvement or resolution of symptoms. CONCLUSION The Neuroform stent seems to be safe and technically effective in the endovascular management of distal cervical and intracranial dissections, with favorable clinical outcomes.

Object Ruptured blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) are rare but carry a high rate of morbidity and mortality. Furthermore, BBAs are very difficult to treat surgically as well as endovascularly. The authors present their experience in treating BBAs with reconstructive endovascular methods. Methods Nine ruptured BBAs in 9 consecutive patients (2 men and 7 women; mean age 50 years, range 42–57 years) were treated using reconstructive endovascular methods between January 2006 and November 2007. Treatment methods and angiographic and clinical outcomes were retrospectively evaluated. Results All 9 BBAs were initially treated with stent-assisted coil (SAC) embolization. This was followed by a second stent insertion using the stent-within-a-stent (SWS) technique in 3, covered stent placement in 3, and SAC embolization alone in 3. All 3 patients who underwent SWS placement had excellent outcomes (Glasgow Outcome Scale Score 5) with complete angiographic resolution of the BBAs. There were no treatment-related complications in the SWS group. Two of the 3 patients who received covered stents had excellent outcomes (Glasgow Outcome Scale Score 5) and complete occlusion of the BBA was achieved. The remaining patient who received a covered stent died of ICA rupture during the procedure. Aneurysm regrowth without rebleeding occurred in the 3 patients who underwent SAC embolization. Two of the 3 recurrent BBAs were treated with coil embolization with a second stent insertion, and as a result these belonged to the SWS group. The other recurrent BBA was treated with a covered stent. Of the 8 surviving patients, 5 underwent SWS, and 3 underwent covered stent placement. All surviving patients had excellent outcomes during the clinical follow-up period (mean 11 months, range 4–26 months); complete BBA resolution and smooth reconstruction of the affected ICA segment was shown on follow-up angiography. Conclusions In the present study, the SWS and covered-stent techniques effectively prevented rebleeding and regrowth of the BBA without sacrifice of the ICA. The SWS and covered-stent techniques can be considered an alternative treatment option for BBAs in selected patients in whom ICA sacrifice is not feasible. Stent-assisted coiling alone seems insufficient to prevent BBA regrowth.

Abstract Objective Blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) are challenging to treat. We assessed the clinical and radiologic outcomes in patients with ruptured BBAs of the ICA treated with wrap-clipping. Methods From November 2016 to January 2020, the clinical and radiologic data of patients with subarachnoid hemorrhage (SAH) caused by ICA BBAs who underwent wrap-clipping were retrospectively analyzed. The clinical outcomes were evaluated according to the modified Rankin Scale (mRS). Radiologic follow-up examinations included digital subtraction angiography (DSA), computed tomography angiography (CTA), and magnetic resonance angiography (MRA). Results Seven patients were enrolled in this study. All BBAs were wrap-clipped successfully, including two BBAs that exhibited intraoperative bleeding and required balloon-assistance during surgery. All patients had favorable clinical outcomes during follow-up. Among the six patients who completed the radiologic follow-up visit, one patient presented ICA occlusion at the 6-month DSA follow-up, but no neurologic dysfunction was noted. We did not observe the progression of ICA stenosis in other patients. Conclusion All BBAs in this study were wrap-clipped successfully and completely occluded. Wrap-clipping is effective for BBAs of the ICA and has favorable clinical outcomes. A multicenter study with a large sample size and a longer radiologic follow-up is necessary.

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.

Anti Platelet Therapy

A blood blister-like (BBL) or dissecting aneurysm should be carefully considered if located at a non-branching site of the supra-clinoid internal carotid artery (ICA). Several surgical and endovascular treatment methods have been proposed but they all carry a relatively high risk of morbidity and mortality. This study evaluated the effectiveness of a novel Silk flow-diverting device (SFD) placed in the early acute stage. Three patients presenting with acute subarachnoid haemorrhage caused by small blisterlike aneurysms of the carotid siphon were treated within 48 hours after admission by placement of SFDs. More than one device was placed to cover the lesion. None of the patients were premedicated and started anti-platelet therapy during the procedure. All aneurysms were successfully occluded. A good outcome was observed in two out of three treated patients. No thromboembolic or haemorrhagic event occurred during or after the procedures, or during follow-up (6–14 months). SFD prevented rebleeding and the use of these devices could be proposed as an option to treat fragile uncoilable BBL aneurysms, even in the early acute phase without anti-platelet premedication. Larger studies and long-terms results are necessary.

OBJECTIVEThere are little data in the literature on the characteristics and natural history of unruptured intracranial aneurysms in children. The authors analyzed their experience with unruptured intracranial aneurysms in the pediatric population at their tertiary care pediatric institution over the last 18 years. The first objective was to assess the imaging characteristics and natural history of these aneurysms in order to help guide management strategies in the future. A second objective was to evaluate the frequency of an underlying condition when an incidental intracranial aneurysm was detected in a child.METHODSThe authors conducted a Research Ethics Board–approved retrospective review of incidental intracranial aneurysms in patients younger than 18 years of age who had been treated at their institution in the period from 1998 to 2016. Clinical (age, sex, syndrome) and radiological (aneurysm location, type, size, thrombus, mass effect) data were recorded. Follow-up imaging was assessed for temporal changes.RESULTSSixty intracranial aneurysms occurred in 51 patients (36 males, 15 females) with a mean age of 10.5 ± 0.5 years (range 9 months–17 years). Forty-five patients (88.2%) had a single aneurysm, while 2 and 3 aneurysms were found in 3 patients each (5.8%). Syndromic association was found in 22 patients (43.1%), most frequently sickle cell disease (10/22 [45.5%]). Aneurysms were saccular in 43 cases (71.7%; mean size 5.0 ± 5.7 mm) and fusiform in the remaining 17 (28.3%; mean size 6.5 ± 2.7 mm). Thirty-one aneurysms (51.7%) arose from the internal carotid artery (right/left 1.4), most commonly in the cavernous segment (10/31 [32.3%]). Mean size change over the entire follow-up of 109 patient-years was a decrease of 0.6 ± 4.2 mm (range −30.0 to +4.0 mm, rate −0.12 ± 9.9 mm/yr). Interval growth (2.0 ± 1.0 mm) was seen in 8 aneurysms (13.3%; 4 saccular, 4 fusiform). An interval decrease in size (8.3 ± 10.7 mm) was seen in 6 aneurysms (10%). There was an inverse relationship between aneurysm size and growth rate (r = −0.82, p < 0.00001). One aneurysm was treated endovascularly with internal carotid artery sacrifice.CONCLUSIONSUnruptured pediatric intracranial aneurysms are most frequently single but can occur in multiples in a syndromic setting. None of the cases from the study period showed clinical or imaging signs of rupture. Growth over time, although unusual and slow, can occur in a proportion of these patients, who should be identified for short-term imaging surveillance.
