Introduction : A 51‐year‐old lady with a past medical history of Essential Hypertension, Hypothyroidism, prior Herpes Zoster infection 8 weeks ago was admitted with complaints of abdominal pain, bilateral flank pain, and restlessness. Her initial workup was significant for hyponatremia and hypokalemia. On the 3rd day of admission, she developed acute hypoxemic respiratory failure which led to intubation. At that time, CTA Chest was not done but CT Chest revealed prominent mucous plugging with left side glass ground opacities, Ultrasound of lower extremities revealed right common femoral vein DVT which led to concerns that she may have suffered from Pulmonary Embolism and led to starting Heparin drip. On the 6th day of admission, she developed Acute Encephalopathy, MRI Brain revealed acute infarcts in bilateral cerebral cortices and cerebella, CT Angiogram Head showed acute subarachnoid hemorrhage in the high posterior right parietal lobe, stenosis of the right high cervical internal carotid artery, and irregular, the appearance of the arterial vasculature throughout and CT Angiogram Neck abrupt change in caliber of the right ICA, 1.5 cm distal to the bifurcation with markedly severe narrowing of the majority of the extracranial right ICA throughout its course. A cerebral Angiogram was done which showed diffuse tandem segments of tandem cervical and intracranial portions of the right internal carotid artery and she was given nitroglycerin was administered as a therapeutic intervention. Lumbar Puncture showed WBC 2, RBC 7, Protein 162, Glucose 64, VZV PCR was negative, CSF VZV IgG Antibody positive at 303 IV (>165 IV indicative of current or past infection). Serum VZV IgG Antibody was positive at >4000 IV. Infectious Diseases were consulted after Lumbar Puncture, they initially started Acyclovir but once the Serum VZV IgG Antibody came back much higher than Serum VZV IgG Antibody levels, their assessment was that VZV vasculitis is unlikely and Acyclovir was discontinued. Eventually, the case was discussed at Neuroradiology which led to us getting a repeat MRA Neck without contrast which showed a concentric T1 and T2 hyperintensity along with a small and irregular caliber right cervical ICA consistent with dissection. She eventually completed a 21‐day course of Nimodipine due to underlying Subarachnoid Hemorrhage. Methods : NA Results : NA Conclusions : Our case demonstrates how it can become difficult to ascertain the etiology of stroke in certain patients. Our patient presented with multiple non‐specific symptoms initially and it was later on due to her Acute Encephalopathy that her Strokes and Subarachnoid Hemorrhage were discovered. It is still difficult to pinpoint whether the cause of strokes was dissection or VZV infection. Lumbar Puncture remains an essential tool to complete work up on uncommon etiologies of stroke.

Abstract: Blister aneurysms are a rare cause of subarachnoid hemorrhage. They are easily overlooked on conventional imaging and catheter angiography due to their small size and unusual anatomic location. Whereas the medical management of subarachnoid hemorrhage is similar to that of saccular aneurysms, the surgical management of blister aneurysms is more challenging due to their unique pathology and higher risk of intraoperative rupture. Special consideration should be made for open management such as preparation of the option of bypass or the emerging use of endovascular techniques such as flow diversion. This chapter reviews the diagnosis and medical and surgical management of blister aneurysms.

Object The object of this study was to evaluate cases of subarachnoid hemorrhage (SAH) from ruptured blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) trunk. Methods The authors performed a single-center, retrospective study. Data analyzed were patient age, sex, Hunt and Hess grade, Fisher grade, time from SAH to hospitalization, aneurysm size and location, collateral capacity of the circle of Willis, time from hospitalization to aneurysm repair, type of aneurysm repair, complications, and Glasgow Outcome Scale (GOS) score at follow-up. Results A total of 211 patients suffered SAH from ICA aneurysms. Of these, 14 patients (6.6%) had ICA trunk BBAs; 6 men and 8 women. The median age was 47.8 years (range 29.9–67.7 years). The Hunt and Hess grade was IV or V in 7 cases, and SAH was Fisher Grade 3 + 4 in 6. All aneurysms were small (< 1 cm), without relation to vessel bifurcations, and usually located anteromedially on the ICA trunk. Three patients were treated with coil placement and 11 with clip placement. Of the 7 patients in whom the ICA was preserved, only 1 had poor outcome (GOS Score 2). In contrast, cerebral infarcts developed in all patients treated with ICA sacrifice, directly postoperatively in 2 and after delay in 5. Six patients died, 1 survived in poor condition (GOS Score 3; p < 0.001). Conclusions Internal carotid BBAs are rare, small, and difficult to treat endovascularly, with only 2 of 14 patients successfully treated with coil placement. The BBAs rupture easily during surgery (ruptured in 6 of 11 surgical cases). Intraoperative aneurysm rupture invariably led to ICA trap ligation. Sacrifice of the ICA within 48 hours of an SAH led to very poor outcome, even in patients with adequate collateral capacity on preoperative angiograms, probably because of vasospasm-induced compromise of the cerebral collaterals.

Supraclinoid Internal Carotid Artery

ABSTRACT OBJECTIVE Aneurysms at nonbranching sites in the supraclinoid internal carotid artery (ICA), known as blood blister-like aneurysms or ICA anterior or dorsal wall aneurysms, are not well understood. To clarify this clinical entity, 7408 patients with subarachnoid hemorrhage who were treated during a 5-year period were analyzed. METHODS Forty-eight patients had aneurysms that were intraoperatively confirmed to be located at a nonbranching site in the supraclinoid portion of the ICA. Neuroradiological and clinicopathological features and outcomes were studied. RESULTS The aneurysms were divided into the “blister type,” with a blood blister-like configuration and fragile walls, and the “saccular type,” with a saccular configuration and a relatively firm neck, like ordinary berry aneurysms. The most frequent origin was the anteromedial wall for both types. ICA dissection was associated only with the blister type, and hypertension was more frequent with the blister type (P = 0.0978). The preoperative conditions of the patients were the same, but the outcomes for patients with blister-type aneurysms were worse, because of frequent intra- and postoperative aneurysmal bleeding. Saccular-type aneurysms were safely clipped. Treatment of blister-type aneurysms by clipping on wrapping material achieved good results, but ICA trapping (P = 0.0952), clipping (P = 0.0146), and wrapping (P = 0.0110) were associated with much worse results. CONCLUSION Blister-type and saccular-type aneurysms have different shapes and wall characteristics. The saccular type can be treated by clipping, whereas the blister type requires clipping on wrapping material. ICA trunk aneurysms may be a better designation to express the diversity of these aneurysms, rather than ICA blood blister-like or anterior or dorsal wall aneurysms.

Backgound:“Blister-like” aneurysms of the supraclinoid internal carotid artery have recently been recognized as having unique pathological and clinical features. Little is known regarding their optimal treatment modality.Methods:We report a case of a “blister-like” aneurysm of the internal carotid artery treated with Guglielmi detachable coil (GDC) embolization. Case Report: A 55-year-old man presented with a Hunt & Hess grade II subarachnoid hemorrhage. Computed tomography revealed diffuse subarachnoid blood. Cerebral angiography demonstrated a broad-based bulge on the medial wall of the right distal internal carotid artery. The patient was taken to the operating room and underwent a right pterional craniotomy and wrapping of this unclippable aneurysm. On postoperative day 11, he developed signs of vasospasm, and repeat angiography showed remarkable growth of the aneurysm. The aneurysm was believed to be amenable to endovascular therapy and was treated by GDC embolization. The patient recovered well and remained neurologically intact on follow-up examinations. Repeat cerebral angiography was performed three and nine months following his initial presentation and revealed a significant aneurysm neck remnant. This neck remnant was treated by repeat GDC embolization 13 months following his subarachnoid hemorrhage.Conclusion:“Blister-like” aneurysms of the internal carotid artery are important to recognize and are difficult to manage using traditional surgical approaches. Early repeated cerebral angiography is indicated and, where appropriate, endovascular therapy should be considered in the management of these patients.

Intracavernous Carotid Artery

Abstract Of 37 patients with 44 intracavernous carotid artery aneurysms (ICCAAns) diagnosed between 1976 and 1988. patients with 20 aneurysms were followed without treatment for 5 months to 13 years (median, 2.4 years). Ten of the 20 ICCAAns were asymptomatic at diagnosis, and 10 were symptomatic. Three of the asymptomatic ICCAAns were symptomatic at follow-up. One of these required clipping because of a progressing cavernous sinus syndrome; the other 2 were minimally symptomatic and have not required treatment. Of the 10 initially symptomatic ICCAAns, 2 had not changed, 4 became more symptomatic, and 4 had symptomatically improved by follow-up. One patient with an ICCAAn that had not changed clinically was lost to follow-up 6 months after diagnosis. Of the 4 ICCAAns that became more symptomatic, 2 continue to be monitored, and 2 required intervention; one with detachable balloon occlusion of the aneurysm with preservation of the internal carotid artery lumen, and the other with gradual cervical internal carotid artery occlusion. The clinical course of this selected group of patients with ICCAAns suggests that the natural history of ICCAAns can be quite variable. Although clinical progression does occur, symptomatic ICCAAns also can improve spontaneously. Therapeutic intervention for asymptomatic ICCAAns should be reserved for patients with aneurysms arising at the anterior genu of the carotid siphon and/or extending into the subarachnoid space, where subarachnoid hemorrhage is most likely. Intervention for symptomatic ICCAAns should be reserved for patients with subarachnoid hemorrhage, epistaxis, severe facial or orbital pain, evidence of radiographic enlargement, progressive ophthalmoplegia, or progressive visual loss.
