Background Intraluminal free floating thrombus (FFT) of the cervical internal carotid artery (ICA) is a potentially high-risk lesion for recurrent ischemic strokes, with no single optimal treatment established. Objective To describe a novel interventional technique for mechanical thrombectomy of intraluminal free floating thrombus using a distal protection filter device and aspiration. Methods We identified two cases where anticoagulation was contraindicated in patients with intraluminal FFT and minimal underlying stenosis. In both cases, a distal protection device was used to extract the thrombus under proximal flow arrest and aspiration. Results Mechanical thrombectomy was successful in both cases, one with “en bloc” removal of the thrombus and one with piecemeal removal. Neither case showed any residual angiographic stenosis or atherosclerotic disease. Conclusion Mechanical thrombectomy using a distal protection device is a novel and technically feasible approach for select cases of cervical intraluminal thrombus. This may represent a therapeutic option in select cases with high risk of anticoagulation and in the unusual subset of younger patients with minimal atherosclerotidc disease.

Introduction: Recently, five published major randomized controlled clinical trials have demonstrated that timely mechanical thrombectomy (MT) of acute ischemic strokes (AIS) with emergent large vessel occlusion (ELVO) is safe and improves functional outcomes. However, data evaluating the efficacy and safety of MT in ELVO patients with concomitant cervical internal carotid artery (cICA) occlusion is limited. The purpose of this study is to evaluate efficacy and safety of MT in ELVO patients with concomitant cICA occlusion Methods: We prospectively analyzed consecutive AIS patients with anterior circulation ELVO who underwent stent-retriever or primary aspiration thrombectomy at two tertiary stroke centers. Outcome measures in our study were 3-month mortality and modified ranking scale (mRS), as well as symptomatic intracranial hemorrhage (sICH). Safety and efficacy outcomes were compared between ELVO patients with and without concomitant cICA occlusion. Results: A total of 137 AIS patients had anterior circulation ELVO and underwent MT (age 63 ± 14, 49% male, median NIHSS 17, IQR [13-20]). ELVO patients with concomitant cICA occlusion (n=19) did not differ in terms of rates of sICH (0% versus 11%, p=0.21), complete recanalization (68 % versus 68%, p=1.00), onset to groin puncture time (minutes [IQR] 268 [211-379] versus 225 [165-312], p=0.47), 3-month mortality (35% versus 26 %, p=0.55), and mRS of 0-2 at 3 months (41% versus 45%, p=0.80) when compared with ELVO patients without concomitant cICA occlusion (n=118). Admission NIHSS was higher among ELVO patients with concomitant cICA occlusion (median [IQR], 18 [15-22] versus 16 [12-19], p=0.01), and they tended to have higher groin puncture to recanalization time (minutes [IQR] 74 [42-97] versus 49 [38-78], p=0.09). The ordinal shift analysis did not show any difference in favorable outcomes in two groups in unadjusted analyses or after adjustment for admission NIHSS and groin to recanalization time (common OR=0.78 [95% CI: 0.27-2.29, p=0.66]). Angioplasty was performed in 11 of 19 ELVO patients with concomitant cICA occlusion. Three patients required stent placement. Discussion: Our study indicates that MT can be performed safely and effectively in ELVO patients with concomitant cICA occlusion.

AbstractWe present a patient suffering from a stroke with a free-floating thrombus extending up to the distal internal carotid artery. The thrombus was totally resolved after a 2-week anticoagulation regimen without leaving behind any severe residual stenosis in the carotid bulb. The optimal treatment of this rare condition remains uncertain. We report some important treatment strategies that have been used in the literature, emphasizing the anticoagulation as the mainstay of therapy. Immediate surgical and interventional manipulations carry the risk of thrombus dislodgement and embolization and should be considered if there are recurrent symptoms despite medical management.

Abstract Objective: Access to the high cervical internal carotid artery (ICA) is technically challenging for the treatment of lesions in and around this region. The aims of this study were to analyze the efficacy of approaching the high cervical ICA through the retromandibular fossa and to compare preauricular and postauricular incisions. In addition, the relevant neural and vascular structures of this region are demonstrated in cadaveric dissections. Methods: The retromandibular fossa approach was performed in four arterial and venous latex-injected cadaveric heads and necks (eight sides) via preauricular and postauricular incisions. This approach included three steps: 1) sternocleidomastoid muscle dissection; 2) transparotid dissection; and 3) removal of the styloid apparatus and opening of the retromandibular fossa to expose the cervical ICA with the internal jugular vein along with Cranial Nerves X, XI, and XII. Results: The posterior belly of the digastric muscle and the styloid muscles were the main obstacles to reaching the high cervical ICA. The high cervical ICA was successfully exposed through the retromandibular fossa in all specimens. In all specimens, the cervical ICA exhibited an S-shaped curve in the retromandibular fossa. The external carotid artery was located more superficially than the ICA in all specimens. The average length of the ICA in the retromandibular fossa was 6.8 cm. Conclusion: The entire cervical ICA can be exposed via the retromandibular fossa approach without neural and vascular injury by use of meticulous dissection and good anatomic knowledge. Mandibulotomy is not necessary for adequate visualization of the high cervical ICA.
