A novel technique for iatrogenic pseudoaneurysm obliteration with ultrasound-guided thrombin foam injection.

Iatrogenic pseudoaneurysms (IPA) are treated with ultrasound-guided thrombin injections (UGTI). We describe a novel technique for IPA repair that applies UGTI with thrombin foam (UGTFI). Successful obliteration of 6 IPAs (IPA without a neck, n = 5; with a neck, n = 1) in 6 patients (2 males, aged 68 ± 1 years, 4 females, aged 59 ± 11 years) was performed by using UGTFI. The dose of administered thrombin was 25-75 IU. No microembolization phenomenon and no serious clinical complications were observed. Treatment of IPA with UGTFI may reduce the embolization rate, risk of IPA cavity thrombin leakage, required drug dose. Use of the thrombin foam could be the next step in the development of the UGTI, particularly in the treatment of IPA without a neck.

IntroductionThe traditional surgical techniques are being replaced by minimally invasive procedures, such as Endovenous Laser (Thermal, Tumescent), and ultrasound foam sclerotherapy (Non-Thermal, Non-Tumescent). The aim of this study was to determine the healing time and rate of venous ulcers (VU) using a Terminal, Axial and Perforator Interruption of the Reflux Source (TAPIRS-LF) protocol. This included Endovascular Laser Treatment and endoluminal venous occlusion with ultrasound-guided foam and a multilayer bandage system until ulcer healing was achieved. Material and methodsA prospective non-controlled trial was conducted on patients with chronic venous leg ulcers (CEAP [clinical, etiological, anatomical and pathological elements] classification C6) during 2015 and 2016. A total of 27 patients aged 18 years and over, presenting with venous insufficiency, VU, and an ankle-brachial index greater than 0.8, were included, with a total of 27 extremities being analysed. All of the patients were subjected to thermal and non-thermal endoluminal occlusion, with endovenous laser treatment in axial venous system, with ultrasound-guided foam in the distal axial superficial venous system and perforator and terminal veins near to the ulcer, using the Tessari method with 3% polidocanol. Follow-up was carried out every week and a Doppler test was performed after 4, 12, and 24 weeks. ResultsThe mean age of the patients was 59.6 years. The active ulcer duration prior to treatment was 11.7 months. The mean VU diameter was 15.06 cm2, and 92.5% VU were seen to be healing at 8 weeks. ConclusionsThe minimally invasive ablation using Terminal, Axial and Perforator Reflux with compression in patients with active VU results in a faster healing during the treatment of chronic venous ulcers.

IntroductionChronic venous ulcers (CVU) are the most common ulcers occurring in the lower limbs, having a high morbidity and place a high financial strain on the health system. The traditional surgical techniques are being replaced by minimally invasive procedures, such as foam sclerotherapy. ObjectiveThe aim of this study was to determine CVU healing times and rates using the terminal, axial and perforator interruption of the reflux source (TAPIRS) protocol, which included an endoluminal venous occlusion with ultrasound-guided foam and a multilayer bandage system until achieving ulcer healing. Material and methodsA prospective uncontrolled trial was conducted on patients with chronic venous leg ulcers (CEAP [clinical, etiological, anatomical and pathological elements] C6) during 2013 and 2014. A total of 17 patients aged 18 years and over, presenting with venous insufficiency, CVU, and an ankle-brachial index greater than 0.8, were included, and total of 17 limbs were analysed. All of the patients were subjected to endoluminal occlusion with ultrasound-guided foam in the axial superficial venous system and perforator and terminal veins near to the ulcer, using Tessari method with 3% polidocanol. Follow-up was carried out at every week and a doppler test was conducted after 4 and 12 weeks. ResultsThe mean age of the patients was 56.4 years. The active ulcer duration prior to treatment was 2.96 years. The study showed that all CVU were healing before 7 weeks, the healing rate was 3.92 cm2/week, and the time until the ulcer was healed was 3.53 weeks (24 days). ConclusionsThe minimally invasive ablation of terminal, axial and perforator reflux with compression in patients is a technique that leads to faster healing times of CVU.
