Case report: Unusual presentation of haemopericardium with haemodynamic instability secondary to a coronary graft pseudoaneurysm treated by an endovascular approach.

Background: We report the successful endovascular treatment of a coronary graft pseudoaneurysm using a technique often seen in intracranial aneurysm coiling.

Case Summary: We present an unusual case of a patient who presents with haemopericardium and haemodynamic instability after saphenous vein bypass grafting. A pseudoaneurysm rapidly expanded from 5 cm to 7 cm over the follow-up period producing compressive mass effect on the lateral right ventricle with transient haemodynamic instability.

Flat detector CT and its applications in the endovascular treatment of wide-necked intracranial aneurysms-A literature review.

Flat detector CT (FDCT) provides cross sectional imaging within an angiographic suite and is increasingly gaining popularity in various areas of interventional radiology, as an alternative imaging modality. Its relatively high spatial resolution improves visualization of intraluminal devices such as intracranial stents or flow-diverters. Device deployment and positioning, in relation to the parent vessel and surrounding structures, are easily assessible with FDCT.

Bare platinum coils vs. HydroCoil in the treatment of unruptured intracranial aneurysms-A single center randomized controlled study.

Purpose: The HydroCoil Embolic System (HES) was developed to improve aneurysm filling to provide superior occlusion efficacy, reduce retreatment rates and enhance long-term durability. We performed a randomized clinical trial to compare the effectiveness of bare platinum coils (BPC) vs. HES for unruptured intracranial aneurysms.

The LVIS/LVIS Jr. stents in the treatment of wide-neck intracranial aneurysms: multicentre registry.

Background: Wide-necked intracranial aneurysms have been a challenge for endovascular techniques. With the advent of adjunctive devices such as balloons or stents, recanalisation rates have decreased secondary to better packing.

Purpose: The purpose of this registry was to evaluate the safety and effectiveness of the new Low-profiled Visualized Intraluminal Support LVIS and LVIS Jr.

Low-profile Visualized Intraluminal Support device (LVIS Jr) as a novel tool in the treatment of wide-necked intracranial aneurysms: initial experience in 32 cases.

Background And Purpose: The focus of this study was to determine ease of deployment, safety and effectiveness of the LVIS Jr device.

Methods: A retrospective analysis was performed of 32 cases comprising 34 aneurysms in which the LVIS Jr device was used for stent-assisted coil embolization of intracranial aneurysms from February to October 2012, including all clinical and angiographic data as well as mid-term follow-up (1-12 months of treatment).

Results: The median age of the patients was 54 years (range 21-76) and 19 (59%) were women.

The next generation HydroCoil: initial clinical experience with the HydroFill embolic coil.

Background: Complete packing of intracranial aneurysms has demonstrated a significant decrease in aneurysm recurrence rates with increased volumetric filling. The HydroCoil Embolization System (HES) was developed to increase volumetric filling within the aneurysm sac to maintain long term occlusion. To further enhance ease of HES deployment, a new next generation embolic coil, the HydroFill coil, was developed.
