Background Benign thyroid nodules are common, and must be treated when symptomatic. Non-surgical minimally invasive modalities, including radiofrequency ablation (RFA), have been widely used with good results. The factors related to the efficacy of RFA are still debated. This study was to evaluate the safety, efficacy and related factors of RFA in the treatment of benign thyroid nodules. Methods A retrospective single-center study was conducted on 251 benign thyroid nodules in 184 patients treated with RFA. The procedure was performed under ultrasound (US) guidance using the trans-isthmic approach and the moving-shot technique. Clinical and US examinations were performed at 1, 3, 6, 12 months, and then at 6 month intervals. Study outcomes were volume reduction ratio (VRR) and complications. Results There were 153 women and 31 men included in the study. The mean age was 43.9 years. The median initial largest diameter and volume of nodules were 30 mm and 6.18 ml. The median length of follow-up was 12 months. Two minor complications were found. The mean VRR was 66.8; 74.3; and 81% after 3, 6, and 12 months, respectively. Initial solidity was a factor related to the efficacy: cystic nodules had higher VRR compared to solid ones. Conclusions RFA is safe, effective and can be used as a routine treatment for benign thyroid nodules. More prospective multicenter studies with long-term follow-up are required to improve the safety and efficacy of RFA.Authors Nguyen Lam Vuong and Le Quang Dinh have contributed equally to this work.
Surgical treatment of abdominal aortic aneurysm in patients with a transplanted kidney is true a challenge. Conventional open repair of the aneurysm requires aortic cross-clamping. Therefore, it can pose a risk of ischemic injury to the transplanted kidney. Endovascular repair, which limits the duration of interruption of blood flow to the transplanted kidney, is a suitable alternative for repair of abdominal aortic aneurysm, if feasible anatomically. Here, we present a case of a 62-year-old woman who was transferred to our hospital because of abdominal pain and had a history of renal transplant 14 years ago. Computed tomography confirmed a large infrarenal fusiform abdominal aortic aneurysm 6 cm in maximal diameter and another 4 cm fusiform aneurysm in the left common iliac artery. We successfully performed endovascular aneurysm repair combined with femoro-femoral bypass. The postoperative course was uneventful, and the patient was discharged on the 5th postoperative day.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
