Ruptured blood-blister aneurysms (RBBAs) of the intracranial internal carotid artery (ICA) are associated with high morbidity and mortality. RBBA has been treated with trapping with high-flow bypass avoiding manipulation of RBBA. In case of the presence of persistent primitive trigeminal artery (PPTA), it is necessary to preserve the antegrade blood flow of PPTA because avoiding ischemic complications. Here, we present a case of RBBA concomitant with ipsilateral PPTA successfully treated with multistaged overlapping braided stents maintaining PPTA flow. A 30-year-old woman suffered from headache and was diagnosed RBBA of the intracranial ICA concomitant with ipsilateral PPTA. A reconstructive endovascular treatment using low-profile visualized intraluminal support (LVIS) stent was performed. However, it has recurred, and RBBA has finally been occluded after overlapping LVIS stents with coil sandwich that is not yet reported in the literature. We report the first case of overlapping LVIS stents with coil sandwich for RBBA.

Ruptured blood-blister aneurysms (RBBAs) of the intracranial internal carotid artery (ICA) are rare, comprising 0.9%–6.5% of all ruptured intracranial cerebral aneurysms and high morbidity and mortality rates.[1] RBBAs are initially treated by trapping using high-flow bypass avoiding manipulation of RBBA. In contrast, persistent primitive trigeminal artery (PPTA) occurs with an incidence of 0.1%–0.6% in cerebral angiography.[2] In patients with RBBA of the intracranial ICA, accompanied by an ipsilateral PPTA, antegrade blood flow in the PPTA (via the ICA) must be preserved. Here, we report the first case of overlapping LVIS stents with coil sandwich for RBBA.

 Case Report

A 30-year-old woman presented with headache and vomiting. Magnetic resonance imaging on admission showed subarachnoid hemorrhage (SAH) with diffuse clotting in the basal cistern [Figure 1]a; however, magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) showed no evidence of aneurysm [Figure 1]b, [Figure 1]c, [Figure 1]d. Concomitantly, a right PPTA, originated from the proximal cavernous portion of the right ICA, was detected with severe hypoplasia of the lower basilar artery; the portion proximal to anastomosis with the vertebral artery was very faint [Figure 1]b, [Figure 1]c, [Figure 1]e and [Figure 1]f. Based on angiographic analysis, the patient was diagnosed with SAH of unknown origin; thus, conservative treatment was initially implemented. Follow-up MRA on day 7 after onset showed de novo aneurysm that was <2 mm in maximum depth on the anterior wall of the supraclinoid segment of the right ICA; thus, the patient was diagnosed with RBBA [Figure 2]a and [Figure 2]b. Reconstructive endovascular treatment (EVT) was chosen. Dual antiplatelet therapy with aspirin and clopidogrel was initiated before the procedure with a 300 mg bolus of aspirin and a 300 mg bolus of clopidogrel; these were followed by postoperative administration of aspirin at 100 mg/day and clopidogrel at 75 mg/day. Under general anesthesia, a 7-Fr Roadmaster 90-cm guiding catheter (Goodman, Aichi, Japan) was positioned at the petrous segment of the right ICA through the right common femoral artery access. A 4-Fr Cerulean G 125-cm catheter (Medikit, Tokyo, Japan) was positioned at the cavernous segment. A Headway 21 microcatheter (MicroVention-Terumo, Tustin, CA, USA) was placed across the blood-blister aneurysm (BBA) neck, and a 4.5 mm × 23 mm low-profile visualized intraluminal support (LVIS) stent was deployed [Figure 2]c. The BBA did not depict after deployment of the LVIS stent [Figure 2]d; however, follow-up DSA on day 14 after onset showed a recurrence of the BBA [Figure 3]a. A second treatment was performed using a stent-in-stent technique with a 4.5 mm × 18 mm LVIS stent [Figure 3]b, and the BBA was almost occluded [Figure 3]c. The postoperative course was good; the patient exhibited a Glasgow Outcome Scale (GOS) score of 5 at discharge. Aspirin and clopidogrel were administered as postprocedural maintenance therapy. Follow-up DSA at 3 months after onset showed BBA regrowth [Figure 4]a and [Figure 4]b. A third treatment was performed, comprising an overlapping LVIS stent (4.5 mm × 18 mm) with coil sandwich between the stents with HyperSoft three-dimensional coil (1 mm × 2 cm; MicroVention-Terumo), using the semi-jailing technique intended for reduction of porosity, by sandwiching the coil near the BBA neck. Finally, the BBA obliterated, and patency of the anterior choroidal artery was confirmed [Figure 4]c, [Figure 4]d, [Figure 4]e.{Figure 1}{Figure 2}{Figure 3}{Figure 4}

The postoperative course was good. Follow-up DSA at 1 year after onset showed complete occlusion of the BBA, and the patient exhibited a GOS score of 5. Clopidogrel was eliminated after 1 year of treatment, whereas aspirin is planned to be administered as lifelong postprocedural maintenance therapy.


RBBA is a rare but clinically important because of its high morbidity and mortality. Several treatment strategies for RBBA have been reported, including open surgery and EVT. However, optimal treatment for BBA remains uncertain.[1],[3],[4] RBBA is fragile and can easily re-rupture at its neck during surgery. Trapping parent artery with high-flow bypass is often used for the treatment of RBBA because neck clipping is difficult and cerebral vasospasm results in ischemic complications in the ipsilateral hemisphere. However, RBBA in a patient with an ipsilateral PPTA cannot undergo trapping with a high-flow bypass because ischemic complications would likely arise in the area perfused by the PPTA. Conversely, EVT has been reported as potentially useful for patients with BBAs recently.[1],[4] In the present case, the preservation of PPTA antegrade flow was needed to preserve normal hemodynamics; therefore, reconstructive EVT was selected.

Reconstructive EVT for BBA of the ICA is effective for the preservation of antegrade flow. However, stent-assisted or balloon-assisted coil embolization for RBBA involves a high level of risk because the BBA is morphologically small, shallow, wide-necked, and fragile; moreover, the height of the BBA neck is generally less than twice the maximal dome height.[5] Many studies have reported the LVIS stent to be safe and effective for the treatment of ruptured intracranial saccular aneurysms.[6],[7],[8],[9] Because the LVIS stent is braided with a single nickel–titanium (nitinol) wire, this type of stent is visible through fluoroscopy. This characteristic facilitates confirmation of complete stent opening and stent wall apposition.[8] In the present case, therefore, single LVIS stent deployment was selected as initial treatment; additional LVIS stent placement through the stent-in-stent technique was chosen as the second treatment. In the third treatment for intractable BBA, an overlapping stent with coil sandwich was placed using a semi-jailing technique; this approach aimed to reduce porosity by sandwiching the coil near the BBA neck. Fortunately, one loop of the coil was embolized within the BBA dome; this accelerated aneurysm thrombosis and healing.

Reconstructive EVT with a flow diverter has been shown to achieve a higher rate of complete occlusion and a lower rate of retreatment than the corresponding EVT without a flow diverter; furthermore, perioperative morbidity and mortality rates, as well as mid- and long-term clinical outcomes, are statistically similar between flow diverter and nonflow diverter groups.[4] Notably, the use of multiple overlapping stents is a safe and effective strategy for correcting BBA remodeling in the supraclinoid ICA, although the number of stents required for effective treatment is currently unclear.[10],[11],[12],[13] Kim et al. described three patients in which successful obliteration of BBAs was performed in the supraclinoid ICA after placement of two or three overlapping nonbraided stents.[14] Conversely, Gaughen et al. showed that three of six patients with BBAs required retreatment after initial treatment with overlapping nonbraided stents.[11] Multiple overlapping braided LVIS stents may be more effective because LVIS stents effectively permit a greater reduction in wall shear stress, compared with overlapping nonbraided stents or single pipeline stents.[15],[16],[17]


Here, we have reported the efficacy of EVT for RBBA in a patient who exhibited an ipsilateral PPTA. Overlapping LVIS stents with coil sandwich for RBBA may provide an effective treatment option, especially when antegrade flow is required.
