“…42 Other ways to lower the stent reocclusion rate are the use of specially coated stents to reduce intimal hyperplasia, e.g., sirolimuseluting stents, 38,41 or the use of encapsulated carbon-lined ePTFE fixed to nitinol stents. 43 However, these are theoretical solutions, and none has demonstrated efficacy in SFA occlusive disease.…”

“…Complications of their use include closure of side branches, restenosis, and thrombosis [5, 6]. The risk of subacute thrombosis may be higher with covered stents than with noncovered stents due to the greater thrombogenic surface area and delayed endothelialization [7]. Stiffness of the stents may predispose to the hinge effect as seen in this case [8].…”

Damage to a covered stent by a thrombectomy device

A 75-year-old with a history of coronary bypass grafting was found to have significant stenoses in a vein graft to the right coronary artery. Symbiot stents, with a polytetrafluoroethylene covering, were used to treat areas in the proximal and middle sections of the graft. The following day, she developed symptoms and signs consistent with an acute inferior infarction. The graft was found to be thrombosed. Thrombectomy was performed using an X-Sizer device, consisting of a helical cutter connected to a vacuum source. This resulted in damage to the stent lining, which led to jamming of the device and subsequent removal of a piece of the stent covering. Treatment was by way of deployment of a long stent within the damaged stent. Recovery was unremarkable. Caution or avoidance of this device appears warranted in the setting of covered stent procedures.

Angiographic thrombus is associated with poorer procedural and clinical outcomes. We report our experience with the X-Sizer thrombectomy device (EndiCOR Medical) from March 2001 to December 2002. Indications for use in 44 patients (33 male; mean age, 60) included myocardial infarction (27), unstable angina (6), periprocedural thrombosis (2), acute (< 24 hr) stent thrombosis (1), and subacute (> 24 hr) stent thrombosis (8). Three cases involved vein grafts. Deployment was successful in 42/44. Difficulty traversing the stent occurred in 5/9 cases of in-stent thrombosis. Median TIMI flow increased from 1 to 2 (P = 0.01) postthrombectomy. Median final TIMI flow was 3. Complications included dissection (1), perforation, device jam on stent (1), disruption of a covered stent (1), distal macro-embolization (4), and transient no-reflow (5). The X-Sizer thrombectomy device improves TIMI flow but does not always prevent distal embolization. Care is needed when treating in-stent thrombosis.

Healing Response of Normal Canine Aorta and Iliac Artery to a Nitinol Stent Encapsulated in Carbon-Lined ePTFE

Abstract: The carbon-lined ePTFE-encapsulated stent is a novel approach to arterial stenting. The progressive endothelialization and lack of inflammatory reaction may provide improved long-term patency. Further study of this stent-graft design is warranted.
