Cancer is one of the major health issues with increasing incidence worldwide. In spite of the existing conventional cancer treatment techniques, the cases of cancer diagnosis and death rates are rising year by year. Thus, new approaches are required to advance the traditional ways of cancer therapy. Currently, nanomedicine, employing nanoparticles and nanocomposites, offers great promise and new opportunities to increase the efficacy of cancer treatment in combination with thermal therapy. Nanomaterials can generate and specifically enhance the heating capacity at the tumor region due to optical and magnetic properties. The mentioned unique properties of nanomaterials allow inducing the heat and destroying the cancerous cells. This paper provides an overview of the utilization of nanoparticles and nanomaterials such as magnetic iron oxide nanoparticles, nanorods, nanoshells, nanocomposites, carbon nanotubes, and other nanoparticles in the thermal ablation of tumors, demonstrating their advantages over the conventional heating methods.

Arterial Chemoembolization

Image-guided local thermal ablation (LTA) plays an important role in the treatment of hepatocellular carcinoma (HCC), especially in patients with HCC who are not suitable for hepatectomy. Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most widely used LTA clinically. Radiofrequency ablation can achieve the best result; that is, a similar therapeutic effect as hepatectomy if the tumor ≤3 cm, while MWA can effectively ablate tumors ≤5 cm. Local thermal ablation has an advantage over liver resection in terms of minimally invasive surgery and can achieve a comparable prognosis and efficacy to liver resection. For borderline liver function, selecting LTA as the first-line therapy may bring more benefits to patients with cirrhosis background. In addition, a combination of multiple therapies for HCC is a good choice, such as LTA combined with transcatheter arterial chemoembolization (TACE), which can achieve a better prognosis than single therapy for larger tumors. For patients who are awaiting liver transplantation, LTA is a good choice. The main problem of LTA needed to be solved is to prevent the local tumor recurrence after ablation in patients with HCC.

Endovenous Thermal Ablation

Endovenous thermal ablation (EVTA) has become the mainstay of treatment for symptomatic varicose veins in the setting of saphenous vein insufficiency. We observed 5 iatrogenic arteriovenous fistulas (AVFs) following thermal ablation of the great saphenous vein (GSV). Postprocedure duplex ultrasound (DUS) results were analyzed for the presence of AVF in any location along or adjacent to the treated saphenous veins. Cases were prospectively followed. English literature was reviewed for any other published reports of AVF after EVTA. Data were compiled using our 5 cases, 2 cases were shared with us by colleagues and 20 cases were reported in the literature. Our center has performed more than 4000 (4155) cases of EVTA over the past 15 years. Five cases of AVFs were detected, 3 were found in asymptomatic patients during routine post-EVTA surveillance. The additional 2 cases presented with signs or symptoms which prompted a DUS after ablation. Including cases in the literature, we were able to identify 2 different types of AVFs. The first type of AVF was demonstrated in 13 cases where the AVF occurred along the treated vein. All of these cases involved ablation of the GSV and 90% of these showed signs of recanalization. The second type of AVF was seen in 14 additional cases where the AVF involved a vein segment adjacent to or remote from the ablated vein. The second type occurred in the GSV in 5 cases, external iliac vein (EIV) in 3 cases, and in the popliteal vein in 5 cases. There is 1 reported case of AVF involving the sural artery after perforator vein EVTA. Three of the type 1 cases were followed and spontaneously resolved; 3 of the type 1 cases were treated with surgical ligation with unreported outcomes. Seven cases did not report any follow-up information. Seven of the type 2 cases were treated, and had spontaneous resolution and 7 were not treated. The follow-up on these cases ranged from 1 month to 6 years. Thermal ablation can result in AVF either along the length of the treated vein or adjacent to the area of ablation. Further study would help elucidate the cause and treatment algorithms.

Introduction: Endovascular ablation of varicose vein either by radiofrequency ablationor laser delivers sufficient thermal energy to incompetent vein segments to produce irreversible occlusion, fibrosis and ultimately disappearance of the vein.Materials and Methods: Three hundred patients with varicosities due to primary or recurrent sapheno-femoral or sapheno-popliteal junction and great or small saphenous veinreflux underwent out-patient and in-patient endovenous thermal ablation between January 2015 to December 2017.The great saphenous vein was ablated from 2-2.5 cm below sapheno-femoral junction to knee and the small saphenous vein was ablated from mid-calf to the sapheno-popliteal junction.Results: Patient returning time to normal activity was 0–1 days returning to normal daily activity were immediately after 4 hours. Duplex ultrasound follow-up (median 3-months) confirmed abolition of sapheno-femoral junction/great saphenous vein and sapheno-popliteal junction/small saphenous vein reflux in all limbs. There were no instances of skin burns or deep vein thrombosis, but, 7 patients developed transient cutaneous numbness involving sural nerve and 1 developed endovenous heat induced thrombosis 3.Conclusions: This is likely to be more effective than conventional surgery, although long-term follow up is required.  Despite being expensive in comparison to open surgery, endovenous thermal ablation is superior in terms of: minimizing pain, avoiding incision, early mobilisation and discharge. Changing the treatment distance from 2 cm to 2.5 cm peripheral to the Deep veins junction may result in a diminished incidence of endovenous heat induced thrombosis 3.

Endovenous Thermal Ablation

Stroke is a very rare but potential fatal complication of endovenous thermal treatment in patients with a right-to-left shunt. To our best knowledge, there are only two reports in the literature of stroke after endovenous thermal ablation of varicose veins, one after endovenous laser ablation and one after radiofrequency ablation and phlebectomy, both treated conservatively. This report describes a successful lysis in a patient with an ischemic stroke associated with bilateral endovenous heat-induced thrombosis class I after endovenous laser ablation of both great saphenous vein and extensive miniphlebectomy in a patient with an unknown patent foramen ovale.
