A Suction Thrombectomy Technique: A Rapid and Effective Method for Intra-Arterial Thrombolysis

Abstract

ObjectiveDuring mechanical thrombolysis, to reduce procedure-related complications and time, the authors have performed a simple suction thrombectomy technique. In this article, the authors describe the technical details and clinical outcomes of this technique.Materials and MethodsFrom January 2013 to December 2013, 14 consecutive acute ischemic stroke (AIS) patients with large cerebral arterial occlusions in the middle cerebral artery (MCA; n = 7), internal cerebral artery (ICA; n = 5), basilar artery (BA; n = 1), and a tandem lesion (ICA and MCA; n = 1) were treated using this technique. The proximal part of the occluding clot was aspirated or captured and retrieved as one piece using a large bored microcatheter by applying negative suction pressure using a 50 mL syringe.ResultsOverall recanalization rate was 85.7% (12 patients). In the 8 patients in whom this technique was used alone, the recanalization rate was 87.5% (7 patients). The median procedural duration was 30 minutes (range 17-112) in these 7 patients. Distal embolism did not occur. Two patients developed post-procedural intracerebral hemorrhages and one was symptomatic. His modified Rankin Scale (mRS) score at 90 days was 4.ConclusionThis technique is a feasible, fast, and safe method for treatment of AIS.

Dual Mechanical Thrombectomy for Recanalization of a Resistant Acute Posterior Circulation Stroke

“…Besides, many operators prefer a trial of direct clot aspiration and if necessary, continue with stent retrievers in both anterior and posterior circulation acute stroke treatments. 3) 6) Such a combination invariably necessitates a DAC and is feasible for dual thrombectomy with the materials and technique described. Dual thrombecomy may be used as a potentially life-saving procedure in the posterior circulation when basilar thrombectomy with aspiration thrombectomy or conventional single-device mechanical thrombectomy fails.…”

Buddy microcatheter technique: Could it be the solution for complex coronary lesions?

“…The one or more buddy wire technique often uses as a track and helps advance of the balloon or the stent towards the target lesion [5,6]. Likewise, the use of microcatheter may significantly facilitate the success and efficiency of chronic total occlusion PCI and intracranial endovascular stroke and aneurysms treatment [7][8][9]. In our report, firstly the buddy wire technique was planned.…”

Cerebrāla infarkta agrīnas attēldiagnostikas un reperfūzijas taktikas saistība ar radioloģisko un klīnisko iznākumu. Promocijas darba kopsavilkums

“…Tās ir jaunākās paaudzes sistēmas, kas tiek uzskatītas arī par progresīvākajām, jo daudzos pētījumos tām ir pierādīti labi klīniskie rezultāti (Fransen et al, 2014;Campbell et al, 2015b). Atsevišķiem pacientiem veiksmīgu rekanalizāciju panāca, izmantojot liela kalibra aspirācijas katetru (penumbra system), pozicionējot to pirms tromba, reizēm pielietojot arī proksimālu aspirāciju kopā ar trombektomijas stentu (Park, 2015).…”
