Ung thư vú thể nội ống (DCIS) là giai đoạn ung thư vú sớm, tế bào ung thư chưa chưa xâm nhập, không phát triển vượt qua màng đáy. Theo thời gian, DCIS có thể phát triển xâm lấn và có thể di căn, vì vậy tất cả phụ nữ được chẩn đoán DCIS đều cần được điều trị.

SUMMARY Results: There were 33 patients with primary hyperparathyroidism who had available preoperative ultrasounds of the parathyroid glands. At surgery, 42 parathyroid adenomas were removed in the 33 patients. Ultrasound correctly revealed 38 adenomas in 42 parathyroid adenomas (90.47%). The most common parathyroid adenomas were located on the posterior of the thyroid lobes (97.4%). All of parathyroids adenoma had well-defined margins (100%) and most showed hypoechogenicity (71.1%), and peripheral vascularity was the most common pattern (92.1%). Conclusion: The most common ultrasonographic findings of parathyroid adenomas was well-defined hypoechoic lesion with peripheral vascularity. Ultrasound plays role in pre-operative localization of the parathyroid tumors and supporting clinical diagnosis. Keywords: ultrasound, primary hyperparathyroidism, parathyroid adenoma.

SUMMARY Objective: We aimed to evaluate the effectiveness of early outcomes of PAE in treating 10 BPH patients with acute urinary retention. Method and results: in this prospective study approved by the institutional review board, a signed informed consent was obtained. There were ten patients with AUR due to BPH from 01/2021 to 12/2022. The patient's successful removal of the bladder catheter after 10-15 days. Postintervention 3 months, average evaluation of IPSS, Qol, PSA (ng/ml), and PV (cm3) decreased 58,48%; 76,03%; 80,95%; 29,97% (ultrasound) 31,75% (MRI); Qmax 12,46(ml/s), PVR 45,84(ml) Conclusion: PAE in patients with AUR due to BPH is safe and effective Keywords: Benign prostatic hyperplasia (BPH), Prostatic arterial embolization (PAE), Acute urinary retention (AUR)

SUMMARY Intraoperative radiofrequency ablation is a new approach for the radical treatment of patients with multifocal hepatocellular carcinoma in different lobes. Originally, patients no longer indicated for radical treatment were now surgically removing the tumor in one lobe and radiofrequency ablation of other tumors in the surgery period time. Objectives and subjects: A retrospective and prospective study conducted between 2020 and 2022, 09 patients with HCC with at least 2 tumors in different lobes underwent intraoperative radiofrequency ablation (IORFA) and followed-up for 3 months at Bach Mai Hospital. Results: All 09 patients with 28 tumors, the number tumors from 02 to 06, each patient underwent surgery to remove 01 large tumor and radiofrequency ablation in surgery for other tumors. All patients responded completely according to mRECIST criteria, no local recurrence, relapsed or died within the first 3 months. Conclusion: Intraoperative radiofrequency ablation is a new effective method approach, help to expand the indications for radical treatment for patients with multifocal hepatocellular carcinoma. Keywords: Intraoperative radiofrequency ablation, hepatocellular carcinoma. *

SUMMARY Purpose: To evaluate the efficacy of radiofrequency ablation (RFA) for benign thyroid neoplasms with a cosmetic score of more than 3. Materials and Methods: This prospective study was performed on 60 patients with benign thyroid nodules with a cosmetic score of more than 3 by radiofrequency ablation under ultrasound guidance at 108 Military Central Hospital from January 1. 2021 to July 2022. We evaluated the change in cosmetic, volume, angiogenesis, and clinical symptoms of patients at 1, 3, and 6 months after the intervention as well as complications, complications during intervention and treatment monitoring. Results : Most patients are female, accounting for 91.7%. The most common age group is from 30 to 50 years old, accounting for 45% and the average age is 43.2 years old. Grade 3 and grade 4 cosmetic scores are equivalent. After 6 months of RFA, the angiogenesis score decreased to 24%, followed by the volume of thyroid nodules decreasing to 37%. The score of symptoms and cosmetics decreased by about 50% compared to before treatment. Complications were mild pain and mild hematoma after RFA, accounting for 5%. Conclusion: Radiofrequency ablation is an effective and safe method for improving the cosmetic point of the neck in the treatment of benign thyroid nodules. Keywords: Benign thyroid nodules, cosmetic score ≥ 3, radiofrequency ablation.

SUMMARY Objective : Researches on blocking afferent pathways of pain sensation to the central nervous system, relieving cancer pain, chronic pain in the upper abdomen is conducted. Methods: This prospective observational study is conducted on 30 patients whose coeliac plexus was blocked from June 2018 to December 2020 at 108 Military central hospitals. Results: Pre-intervention patients have been severe pain with a VAS score ≥ 6, which greatly affected the quality of life. After coeliac plexus block, 22/30 patients achieved the expected analgesia. The most common side effect is diarrhea. No serious complications Conclusion: The absolute–alcohol injection technique to block the coeliac plexus by computed tomography and Maxio robot-guided offer high precision, the efficacy of initial treatment, and low complication rate. Key words : Cancer pain, coeliac plexus block

SUMMARY Purpose: Describe the technique and evaluate imaging results of the fluoroscopic inguinal intranodal lymphangiography technique. Subjects and methods : Case series study on 37 patients, all were done fluoroscopic inguinal intranodal lymphangiogram. Results: The study was conducted on 37 patients (11 men, 26 women), mean age, 56. The technique was successful in all patients (100%), detected anatomic variants of lymphatic central in 30% of patients, leak point 31/37 cases accounting for 84%. The average time to observe the target lymph vessel was 35.3 ± 20.2 minutes. Conclusions : fluoroscopic inguinal intranodal lymphangiography is a safe procedure, provides visualization of central lymphatic anatomy, detected leak points, and guides for percutaneous lymphatic interventions.
