ABSTRACT

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. Thyroid function cosmetic and symptoms scores and satisfaction degree were evaluated. Results: A total of 30 symptomatic benign thyroid nodules were treated by microwave ablation using a power between 15 and 30 W depending on the size of the nodule to be treated. The volume reduction rates in months 1, 3, 6, 9, 12, and 24 after ablation were 32, 59, 67, 69, 73, and 81%, respectively. The mean symptom score and mean cosmetic score before treatment were 4 and 3, respectively, while after treatment they dropped to 3 and 1, respectively. Thyroid function indicators fluctuated in the normal range and those with hyperthyroidism recovered to normal parameters. One case of temporary laryngeal paralysis occurred postoperatively and fully recovered in less than 3 months. Conclusions: The novel microwave ablation system presented herein can help achieve good clinical success rate in benign thyroid nodules with a satisfying safety profile. The microwave ablation performed with the multiple overlapping ablation technique could be a good alternative to surgery and radiofrequency ablation in the management of benign thyroid nodules.

ABSTRACT

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. The advantages of radial artery access have been widely proven, nevertheless the use of upper limb veins in neurointervention are rarely reported. We present five cases of the simultaneous arteriovenous approach through the radial artery and superficial veins of the forearm for the treatment of intracranial neurovascular diseases.

ABSTRACT

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. One significant usage limitation of flow diverter devices is the parent artery diameter, since the maximum opening of the sizes available are recommended for vessel diameters between 5.2-5.75 mm. Here we present the first clinical use of the largest flow diverter available, the 6×50 mm DERIVO embolization device (Acandis GmbH & Co. KG, Pforzheim, Germany), into the arterial circulation for a cervical internal carotid artery endovascular reconstruction. This is a new device for large or fusiform aneurysms requiring flow diversion, especially located in the vertebrobasilar system or extracranial segments.

ABSTRACT

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. Here we present a novel balloon technique that was successfully used to realign an in situ flow diverting stent that had prolapsed into a large aneurysm. This represents a useful salvage technique and should be considered when encountering this potential complication.

ABSTRACT

Enterocutaneous fistula is a challenging entity and a gold-standard treatment is not settled so far. Here, we describe the successful closure of a duodenocutaneous fistula with the use of the Biodesign enterocutaneous fistula plug (Cook Medical), which is derived from a biological plug that has been used in recent years in order to close anorectal fistula tracts.
