Pseudo-no-Reflow Phenomenon in Carotid Artery Stenting using FilterWire EX: Successful Recovery by Aspiration Thrombectomy
Distal protection devices such as FilterWire EX have been widely used in carotid artery stenting, however, the large amount of atherothrombotic debris entrapped in the filter could reduce or stop antegrade flow. We present a case of pseudo-no-reflow phenomenon after postdilatation of the stent in a patient with asymptomatic carotid artery stenosis. After several passes using an Export Aspiration catheter, normal flow in the internal carotid artery was restored. Aspiration thrombectomy can successfully recover pseudo-no-reflow phenomenon
Lumbopelvic Sagittal Alignment and Foraminal Height from Single Interbody Cage in L5-S1 Segment: Comparison between Anterior Cage for OLIF (Oblique Lumbar Interbody Fusion) and Curvilinear Cage for TLIF (Transforaminal Interbody Fusion)
Objective To evaluate a radiological difference between the oblique lumbar interbody fusion (OLIF) L5-S1 and transforaminal lumbar interbody fusion (TLIF) L5-S1 procedure. Methods 16 patients who underwent single-level OLIF L5-S1 and 32 patients of TLIF L5-S1 were retrospectively reviewed. Assessment of the lumbopelvic parameters and the height of disc space and L5-S1 neural foramen was performed before surgery as well as a month after surgery. Results Preoperatively, OLIF L5-S1 group and TLIF group showed similar lumbar lordosis (LL), segmental lordosis (SL), pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS); (p=0.08, 0.48, 0.67, 0.19 and 0.12, respectively). Postoperatively those parameters did not show statistically significant differences between two groups (p=0.17, 0.32, 0.53, 0.16 and 0.19, respectively). In terms of disc and foraminal height, the OLIF L5-S1 group showed significant greater increase of posterior disc height and foraminal height (p=0.01 and 0.00). There was no significant differences between the two groups in mean VAS and ODI score over the follow-up period. Conclusion This study demonstrates that both OLIF L5-S1 group and TLIF L5-S1 group had similar ability of achieving lumbopelvic alignment however, increase of foraminal height was greater in patients with OLIF L5-S1 group
