Data on the timing, durability and occlusion rate of treating ruptured blister cerebral aneurysms using the Pipeline Embolization Device (PED) are limited. ⋯ Complete occlusion of a ruptured blister aneurysm can occur immediately after PED placement. In ruptured blister aneurysms with contrast stagnation after PED treatment, early angiographic occlusion was confirmed as early as 6 weeks and continued with medium-term durability.

To determine if lumbar synovial cyst rupture in symptomatic patients results in improved clinical outcome when using direct tandem and/or coaxial percutaneous CT guided techniques. ⋯ Direct tandem and/or coaxial percutaneous CT guided techniques for rupture and treatment of symptomatic lumbar synovial cysts reduces recurrence rates and therefore helps avoid more invasive open surgical procedures in this group of patients.

In acute ischemic stroke, good outcome following successful recanalization is time dependent. In patients undergoing endovascular therapy at our institution, recanalization times with the Solitaire stent were retrospectively evaluated to assess for the presence of a learning curve in achieving rapid recanalization. ⋯ There is a learning curve involved in the efficient use of the Solitaire stent in endovascular acute stroke therapy. Along with improvements in patient transfer to angiography and improved efficiency with intracranial access, mastering this device contributed significantly towards reducing recanalization times.

Traditional balloon assisted coil embolization techniques for intracranial aneurysms require a single lumen balloon to remodel the aneurysm neck and a separate microcatheter to place coils. Here we report utilization of a single coaxial dual balloon microcatheter to achieve both coil placement and neck remodeling in a series of intracranial and cervical arterial aneurysms. ⋯ Aneurysmal neck remodeling and coil embolization can both be achieved using a single coaxial dual lumen balloon microcatheter in selected oblong intracranial and cervical arterial aneurysms.

In order to determine the risk factors related to aneurysm rupture, we studied the aneurysms at the paraclinoid segment of the internal carotid artery by applying morphologic and hemodynamic numerical analyzes. ⋯ Irregular shape, larger EL and concentrated inflow jet were independently associated with the rupture status of paraclinoid aneurysms. These findings need to be further confirmed based on large multicenter and multipopulation data.
