Endovascular Treatment with Two Overlapping Micromesh-Covered Stents and Balloon Guide Catheter for Symptomatic Carotid Pseudoaneurysm Ten Years after Eversion Endarterectomy

Abstract BACKGROUND The effectiveness of balloon guide catheter (BGC) use has not been prospectively studied and its added value for improving reperfusion in acute ischemic stroke (AIS) treatment has only been reported in studies in which no contact aspiration was combined with the stent retriever (CA + SR). OBJECTIVE To compare the reperfusion results and clinical outcomes with and without BGC use when a combined CA + SR strategy is employed in first line to treat AIS. METHODS From January 2016 to April 2019, data from the ETIS registry (Endovascular Treatment in Ischemic Stroke) were reviewed. We included patients having undergone endovascular treatment with a combined CA + SR strategy and use or not of a BGC according to the operator's discretion. We compared BGC and nonBGC populations with matching and inverse probability of treatment weighting propensity scores. Primary outcome was the final near-complete/complete revascularization (mTICI2c/3) rate. Secondary outcomes included clinical outcomes and safety considerations. RESULTS Among 607 included patients, BGC was used in 32.9% (n = 200), and 190 matched pairs could be found. We found no significant difference in final mTICI2c/3 between patients with and without BGC (60.1% in BGC group compared to 62.7% in nonBGC group (matched RR, 0.92; 95%CI, 0.80 to 1.14)), first-pass mTICI2c/3 (35.1% vs 37.3%, matched RR, 0.94; 95%CI, 0.68 to 1.30), clinical outcome (matched RR of 1.12 (95%CI, 0.85 to 1.47) for favorable outcome. CONCLUSION The reperfusion and clinical results with and without BGC use are not significantly different when combined CA + SR are used as a first-line strategy for large vessel occlusion in the setting of AIS.

Objectives The aim of this study was to report on the safety and feasibility of secondary relining with focal flaring of novel-generation balloon-expandable covered stents for endovascular treatment of significant diameter mismatch in the aorto-iliac territory. Significant diameter mismatch was defined as >20% difference in the nominal diameter between the intended proximal and distal landing zones. Methods Patient A was an 84-year-old man with prior abdominal aortic aneurysm open repair with a straight 20 mm Dacron tube. He presented with a right common iliac artery aneurysm (Ø88 mm) with contained rupture. The Gore Viabahn endoprosthesis (9 mm × 5 cm) was inserted proximally about 15 mm above the occluded ostium of the internal iliac artery. Subsequently, the BeGraft Aortic® (16 mm × 48 mm) was inserted proximally up to the common iliac artery origin; its proximal portion was flared to 22 mm. Patient B was a 77-year-old man with prior endovascular abdominal aortic aneurysm repair with a Medtronic Endurant stent-graft. He presented with occlusion of the right limb of the aortic endoprosthesis and thrombosis that extended down to the level of the superficial femoral artery. After mechanical thrombectomy, two Gore Viabahn endoprosthesis (first one, 8 mm × 10 cm; second one, 10 mm × 15 cm) were inserted into the right iliac limb. Subsequently, the BeGraft Aortic® (12mm × 39mm) was inserted proximally up to the gate of the aortic stent-graft; its proximal portion was flared to 16 mm. Results Technical success and clinical success were achieved in both patients. Imaging follow-up (6 months for Patient A, 12 months for Patient B) showed correct placement of all stent-grafts without any graft-related adverse event. The patients remained free from new reinterventions or recurrent symptoms. Patient A died 8 months after the index procedure from acute respiratory failure after community acquired pneumonia. Conclusion Secondary relining with focal flaring of novel-generation balloon-expandable covered stents for endovascular treatment of significant diameter mismatch in the aorto-iliac territory is safe and feasible. Although mid-term results seem to be effective, longer follow-up is warranted to establish durability of the technique.

Abstract We present a case of a patient with pseudotumor cerebri (PC) and transverse/sigmoid junction sinus (TSJS) stenosis treated with stenting venoplasty. A 54-yr-old man with a history of hypertension, hyperlipidemia, and chronic obstructive pulmonary disease presented with subacute onset of progressive headaches, blurred vision, and papilledema. He was clinically diagnosed with PC. Left TSJS stenosis was suspected on magnetic resonance venography and confirmed with digital subtraction angiography and venography. During angiography, venous pressures were measured along the intracranial venous system revealing a significant drop compared with pressures obtained from the superior sagittal and sigmoid sinuses. For 7 d prior to venous sinus stenting, he was prescribed antiplatelet therapy with aspirin (350 mg/d) and clopidogrel (75 mg/d). Patient consent was obtained prior to performing the procedure; institutional board approval is not required for the report of a single case. Under conscious sedation and systemic heparinization, the patient underwent endovascular stenting of the left TSJS with an open-cell carotid stent (Precise 7 × 40 mm; Cordis, Milpitas, California). Successful left TSJS reconstruction transpired with no procedure-related complications. The patient was discharged home 1 d postprocedure. After 2 mo of dual antiplatelet therapy, clopidogrel was discontinued. At the 1-yr follow-up, he had resolution of papilledema and notably less intense headaches. Venous sinus stenting is an effective endovascular treatment for symptomatic patients with PC and sinus stenosis. Venous pressure measurement is imperative for patient selection. Adequate venous access with a 6-French guide catheter into the sigmoid sinus and an intermediate catheter into the transverse sinus is crucial to navigate a stent through the acute angles of the TSJS and jugular vein.
