Objective: To study the diagnostic value of fluorescent lymphography for sentinel lymph node biopsy in breast cancer.

Material and methods: The cohort study, conducted at 4 specilized centers between June 2019 and March 2024, included 333 patients with cT1-4 N0-1M0 breast cancer. 50 patients received neoadjuvant systemic therapy, 14 of them had single metastases, confirmed by cytological or histological methods, which clinically completely regressed after systemic treatment. Immediately before the operation, 1 ml (5mg) of indocyanine green was injected subareolarly or subcutaneously into the tumor projection. Fluorescence imaging was performed using various devices for ICG navigation in the open surgical field - MARS, IC-Flow, Stryker SPY-PHI, IC-GOR. In 78 patients after sentinel lymph node biopsy standard axillary lymphadenectomy was performed.

Results: Detection level was 99.1%. The average number of sentinel lymph nodes was 3.4. Metastatic lesions of sentinel lymph nodes were detected in 54 of 330 patients (16.4%). The average number of metastatic lymph nodes was 1.6; in 90.7% of cases metastases to 1-2 lymph nodes were registered. Intraoperative morphological examination revealed metastases only in 59% of cases. No systemic adverse events were recorded. The false-negative error rate in the group of patients who underwent axillary lymphadenectomy was 6.6%. The overall accuracy of fluorescent lymphography for sentinel lymph node biopsy in breast cancer was 94%.

Conclusion: The SLNB technique using fluorescence lymphography is safe and highly accurate as a stand-alone method.

Objective: To identify the factors associated with normal leukocyte count and C-reactive protein (CRP) in adults with acute appendicitis.

Material and methods: A retrospective cohort study included patients aged 18-60 years after surgeries for acute appendicitis. Convenience sampling was used to select medical records, and variables such as age, sex, weight, height, origin, self-medication, diabetes (DM2), high blood pressure (HBP), type of appendicitis, duration of illness, preoperative time, type of appendectomy, operative time, and hospital stay were analyzed. Patients were categorized into those with normal and abnormal inflammatory parameters. The SPSS version 28 software was used for analysis.

Results: We included 333 patients; 11.11% ones had normal inflammatory parameters. Both groups had mean age of approximately 33 years. Men comprised 56.76% and 57.43%in both groups, respectively. The abnormal group had shorter mean preoperative time, and catarrhal appendicitis was more common in the normal group. Multivariate analysis revealed that rural origin and self-medication were significantly associated with normal inflammatory parameters.

Conclusion: The prevalence of normal inflammatory parameters in acute appendicitis patients was 11.11%. Rural origin, self-medication, shorter preoperative time, and catarrhal appendicitis were significantly associated with normal inflammatory parameters in this context.

Objective: To analyze learning curves and appropriate experience on the features of mini-bypass surgery in 341 obese patients.

Material and methods: A total of 341 laparoscopic mini-gastric bypass surgeries performed by one surgeon were studied. The median age of patients was 40.5 [34; 48.3] years. There were 284 (83.2%) women and 57 (16.8%) men. The median BMI was 45 [40;52] kg/m².

Results: The period of MGB development consisted of 138 interventions. Surgery time was 120 [100; 130] min and 90 [82.5; 100] mins after development of this technique (p=0.001). Complications occurred in 5 (1.5%) patients (1 patient with Clavien Dindo grade IIIA and 4 ones with grade IIIB). Of these, there were 3 patients with stapler suture defects. There were no complications only in the 4th quartile of surgeries. Surgical experience significantly affects postoperative outcomes. Surgery time was more influenced by surgical skill rather technique of anastomosis imposing.

Conclusion: Polynomial regression objectively characterizes development of surgical skills lasting 138 interventions. MGB is safe for morbid obesity with a complication rate of 1.5% and no mortality.

A 72-year-old female patient with chronic kidney disease stage presented with multiple parathyroid adenomas and tertiary hyperparathyroidism. SPECT/CT with ^99mTc-MIBI revealed accumulation of radiopharmaceuticals in 2 out of 4 parathyroid glands. Ultrasound established localization of all parathyroid glands. Subtotal parathyroidectomy with excision of 3 glands and resection of half of the fourth gland was performed. Intraoperative indocyanine green angiography was performed to identify all parathyroid glands and remnant perfusion. There was normal parathyroid function after 6 months.

Objective: To compare the short-term and long-term outcomes of hybrid interventions after various infrainguinal reconstructions (restoration of blood flow through superficial femoral artery and pulsatile blood flow through deep femoral artery) in patients with iliac-femoral arterial disease.

Material and methods: A retrospective analysis included patients after hybrid iliac-femoral interventions between 2014 and 2018. These interventions included stenting of iliac arteries and various open infrainguinal reconstructions. The first group (n=41) consisted of patients who underwent reconstruction of superficial femoral artery, the second group (n=88) - restoration of pulsatile blood flow in deep femoral artery. We analyzed the Rutherford score, perioperative complications, primary patency rates and limb salvage rates after 12 months in both groups.

Results: Significant improvement (Rutherford score +3) was achieved in 28 (70%) and 14 (15.9%) patients, respectively (p<0.05). There were no significant between-group differences in the number of postoperative complications. Surgery time was longer in the first group (median 160 and 130 min, respectively, p<0.05). However, intraoperative blood loss was similar. Primary patency rates after 12 months were 82.4% and 95.1%, respectively (p=0.054). Limb salvage rates after 12 months were 94.7% and 100%, respectively (p<0.05).

Conclusion: This study highlights the potential advantages of restoring pulsatile blood flow through the deep femoral artery in hybrid interventions. Higher primary patency and limb salvage rates in the second group indicate better long-term outcomes after restoration of blood flow through the deep femoral artery. Further prospective studies are needed to confirm these results and determine the underlying mechanisms of differences.

Malignant lesions of tracheal bifurcation usually lead to respiratory failure and risk of mortality. Airway stenting is the only minimally invasive method for these patients. The authors present a patient with T4N3M0 left-sided lung cancer (inoperable stage IIIc) complicated by respiratory failure due to tracheal bifurcation obstruction. Bilateral stenting by self-expanding stents with perforated coatings was effective for airway recanalization and provided subsequent chemotherapy.

The article is devoted to historiography of perfluorocarbons, as well as discoverers of perftorane and their discoveries. There would be no national priority in transfusiology without these discoveries. Perftorane is the only one of the world series of perfluorocarbon emulsion drugs that has passed all phases of clinical trials. Perftorane has been used in clinical medicine for 30 years.

The authors present treatment of rhabdomyosarcoma of the gluteal region with secondary lesion of the lung and chest wall. Features of chest wall defect closure are analyzed.

Trauma is one of the leading causes of disability and mortality in working-age population. Abdominal injuries comprise 20-30% of traumas. Uncontrolled bleeding is the main cause of death in 30-40% of patients. Among abdominal organs, spleen is most often damaged due to fragile structure and subcostal localization. In the last two decades, therapeutic management has become preferable in patients with abdominal trauma and stable hemodynamic parameters. In addition to clinical examination, standard laboratory tests and ultrasound, as well as contrast-enhanced CT of the abdomen should be included in diagnostic algorithm to identify all traumatic injuries and assess severity of abdominal damage. Development of interventional radiological technologies improved preservation of damaged organs. Endovascular embolization can be performed selectively according to indications (leakage, false aneurysm, arteriovenous anastomosis) and considered for severe damage to the liver and spleen, hemoperitoneum or severe polytrauma. Embolization is essential in complex treatment of traumatic vascular injuries of parenchymal abdominal organs. We reviewed modern principles and methods of intra-arterial embolization for the treatment of patients with traumatic injuries of the liver and spleen.

Objective: To evaluate the immediate results of ankle replacement with original prosthesis in a patient with severe post-traumatic deformation of the distal tibia.

Material and methods: When developing the original design of ankle prosthesis, we considered foreign analogues of classical and revision models of ankle prostheses taking into account their shortcomings. In this case, an integrated approach was used. Extensive work has been carried out to select materials for prosthetic components. Experimental work with mesenchymal stromal cells of bone marrow was aimed at testing cytotoxicity and biological compatibility. The staff of the department of designing biomechanical structures of the Research Institute of Bionics and Personalized Medicine of the Samara State Medical University carefully studied the proposed design of endoprosthesis using the Ansys software. After cadaver tests on full-scale models, we performed surgical intervention in a patient with severe post-traumatic deformity of the lower third of the left tibia.

Results: Our studies revealed convenience and certain advantages of intraoperative installation of original ankle prosthesis. Along with this, this clinical example indicated come features that must be taken into account in revision ankle replacement to avoid possible postoperative consequences.

Conclusion: Original ankle prosthesis makes it possible to replace the distal tibia and preserve limb function.
