Multiple overlapping microwave ablation in benign thyroid nodule: a single-center 24-month study.

Objective: This study aimed to evaluate the safety and long-term efficacy using the multiple overlapping ablation technique with a novel non-cooled microwave system in benign symptomatic thyroid nodules.

Methods: This prospective cohort single-center study collected complication data from the start of the procedure to 30 days postoperatively and evaluated the safety and effectiveness with a follow-up of 24 months. Ultrasound examinations were performed to determine the volume shrinkage during follow-up.

Arm-only access for combined transarterial and transvenous neurointerventional procedures.

A simultaneous arterial and venous approach has been widely described for the endovascular treatment of dural arteriovenous fistula (DAVFs) and recently for arteriovenous malformation (AVMs). Conventional venous approaches are performed by direct internal jugular puncture or by femoral access. Although complication rates are low, there are potential life-threatening complications that should be avoided.

Optical coherence tomography: Translation from 3D-printed vascular models of the anterior cerebral circulation to the first human images of implanted surface modified flow diverters.

Background: The new generation of flow diverters includes a surface modification with a synthetic biocompatible polymer, which makes the device more biocompatible and less thrombogenic. Optical coherence tomography (OCT) can be used to visualize perforators, stent wall apposition, and intra-stent thrombus. Unfortunately real world application of this technology has been limited because of the limited navigability of these devices in the intracranial vessels.

Internal Carotid Artery Reconstruction with a "Mega Flow Diverter": First Experience with the 6×50 mm DERIVO Embolization Device.

Endoluminal reconstruction with a flow diverter device has emerged as a viable and often preferable alternative to traditional techniques for the treatment of intracranial aneurysms. Precise measurement and device selection are mandatory steps when considering flow diverters usage in order to avoid potential complications. In this sense, incomplete wall-apposition has been described as a predictive factor for immediate in-stent and delayed thrombosis after stent use.

Novel balloon application for rescue and realignment of a proximal end migrated pipeline flex embolization device into the aneurysmal sac: complication management.

The pipeline embolization device (PED) has become a routine firstline option for the treatment of an increasing population of intracranial aneurysms at many neurovascular centers. Intraprocedural complications during PED deployment, or complications associated with migration of the device, are rarely reported problems. Significant mismatch in luminal diameter between the inflow vessel and the outflow vessel or excessive dragging-stretching of the PED have been related to 'watermelon seed' or 'accordion' effects, respectively, resulting in stent migration.
