Occlusion of a left internal mammary artery graft side branch during attempts to deliver an amplatzer vascular plug.
(2/14)
We present a case of angina in a patient with a left internal mammary artery graft that had a large side branch. Closure was attempted using an Amplatzer vascular plug but during attempts to position the device, the side-branch occluded, likely due to dissection, obviating the need for device deployment.

Percutaneous device closure of patent foramen ovale using the Premere occlusion device: initial experience, procedural, and intermediate-term results.
(3/14)
BACKGROUND: Percutaneous device closure is a therapeutic option in patients with presumed stroke complicating paradoxical emboli. Newer devices with lower profiles and potentially reduced thrombogenicity have emerged, such as the Premere PFO occlusion device (St Jude Medical, Inc.); there are limited data on the efficacy and procedural experience with this device. METHODS: We evaluated our initial experience with the Premere device in a contemporary patient cohort, comparing the procedural and intermediate follow-up characteristics with the currently utilized Amplatzer PFO occluder. RESULTS: Both devices were similarly effective in terms of immediate procedural success and defect closure. Procedures using the Premere device tended to be longer and required larger vascular access-sheath sizes; there were also significantly more adverse events in the Premere group (4/29) compared to the Amplatzer group (0/42; P=.02), including 1 retroperitoneal bleed, 2 hematomas, and 1 myocardial infarction. CONCLUSIONS: While the Amplatzer device may offer advantages in terms of safety and procedural simplicity, this in part reflects the early procedural experience with this new device. The Premere and Amplatzer PFO occlusion devices are similarly effective in achieving PFO closure when applied to appropriate anatomy and should be considered complementary when performing such procedures.

The combined use of heavy and light silicone oil in the treatment of complicated retinal detachment with 360 masculine retinal breaks: tamponade effect or filling effect?
(7/14)
INTRODUCTION: This study aims to report the safety and effi cacy of the combined use of 70% Densiron(R)-68 and 30% polydimethysiloxane as a temporary vitreous substitute after pars plana vitrectomy (PPV) in selected cases of retinal detachment with superior and inferior retinal breaks. MATERIAL AND METHODS: Fifty consecutive eyes of 50 patients affected by complicated retinal detachment with retinal breaks of the superior and inferior quadrants associated with proliferative vitreoretinopathy (PVR) of grade C2 or more, underwent a pars plana vitrectomy and a combination internal tamponade with 70% Densiron(R)-68 and 30% silicone oil. The main outcome measures were visual acuity, retinal attachment, intraocular pressure (IOP) and incidence of complications. RESULTS: The mean best-corrected visual acuity rose from 1.4 logMAR to 0.7 logMAR (P <0.01). Initial retinal reattachment was achieved in 48 (96%) patients. In 15 patients (30%), IOP increased over 21 mmHg. The main complications were redetachment at the 3 month follow-up in 12/48 cases (25%) and cataract formation in 13/21 phakic eyes (62%). CONCLUSION: This combination tamponade comprised lighter and heavier oil compounds was well tolerated and effective. It may be a useful tool for the treatment of retinal detachment complicated with breaks and PVR involving the upper and lower quadrants. (+info)
