Aim. To study the long-term results of surgical treatment of patients with thyroid adenomas. Methods. From 2004 to 2006, 667 patients with follicular adenomas of the thyroid gland, including 134 (20.1%) men and 533 (79.9%) women, were operated on in the surgical department №2 of city clinical hospital №11 of Ryazan. 3 groups of patients were defined: group 1 operated on for solitary adenomas of the thyroid gland, 103 patients, hemithyreoidectomy performed; group 2 operated on for multiple adenomas of the thyroid in both lobes, 101 patients, thyroidectomy performed; group 3 32 patients operated on for multiple adenomas of the thyroid in the same lobe, hemithyreoidectomy performed. Patients were examined 14 years after the surgery. Results. Hypothyroidism was diagnosed in: group 1 18 (17.5%) patients, group 2 101 (100%), group 3 0. All patients with hypothyroidism were compensated with hormone replacement therapy. Permanent hypoparathyroidism was diagnosed only in group 2 8 (4.8%) patients. Unilateral laryngeal paralysis was found in group 1 in 1 (0.9%) patient, group 2 in 2 (1.9%) patients, group 3 contained no such patients. Recurrence (node more than 1 cm according to ultrasound) was observed in group 1 in 12 (11.7%) patients; fine-needle aspiration found colloidal nodes in 8 (7.8%) patients (Bethesda II), in 4 (3.9%) follicular tumor (IV). Group 2 had no recurrences. In group 3 11 (34.3%) patients had recurrence; fine-needle aspiration found colloidal nodes in 1 (3.1%) patient (Bethesda II), in 10 (31.3%) follicular tumor (Bethesda IV). Conclusion. In solitary adenomas it is possible to perform organ-saving operations, which reduces the percentage of postoperative complications; in multiple adenomas, the optimal volume of surgery is thyroidectomy; when multiple adenomas are localized in one lobe, the chance of recurrence of the disease (31.3%) is high leading to re-surgery.

Aim. Analysis of hospital and long-term results of carotid endarterectomy (CEA) in different periods of acute cerebrovascular event (ACVE). Materials and Methods. The given study was retrospective and was conducted using the method of patients sampling. In the period from 2010 to 2019, 1113 patients with ACVE in history who were later conducted CEA, were selected. Depending on the time interval between the last ACVE and CAE, all the patients were divided into 4 groups: the 1st group in the acutest period of ACVE (1-3 days) (n=24; 2.2%); the 2nd group in the acute period of ACVE (up to 28 days) (n=493; 44.3%); the 3rd group in the early rehabilitation period of ACVE (up to 6 months) (n=481; 43.2%); the 4th group in the late rehabilitation period of ACVE (up to 2 years) (n=115; 10.3%). The long-term period was 34.812.5 months. Results. In the hospitalization period of observation the following complications were found: lethal outcome ((group 1 0%; group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р=0.16)); myocardial infarction ((group 1 0%; group 2 0.4% (n=2); group 3 0%; group 4 0.9% (n=1); р=0.35)); ACVE/transient ischemic attack (TIA), ((group 1 4.2% (n=1); group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р1-2=0.01; р1-3=0.009; р1-4=0.01)). By the end of hospitalization period the composite endpoint consisting of lethal outcome + myocardial infarction + ACVE/TIA made in group 1 4.2% (n=1), in group 2 1.2% (n=6), in group 3 0.4% (n=2), in group 4 2.6% (n=3), р=0.08. Complications of the long-term follow-up period were: lethal outcome from all causes ((group 1 25% (n=6); group 2 5.5% (n=27); group 3 7.3% (n=35); group 4 14% (n=16); р1-2=0.002; р1-3=0.008; р2-4=0.012)); lethal outcome from cardiovascular causes ((group 1 4.2% (n=1); group 2 3.6% (n=18); group 3 4.8% (n=23); group 4 5.2% (n=6); р=0.79)), myocardial infarction ((group 1 12.5% (n=3); group 2 3.6% (n=18); group 3 5.4% (n=26); group 4 6.1% (n=7); р=0.15)), ACVE/TIA ((group 1 16.6% (n=4); group 2 6.3% (n=31); group 3 6% (n=29); group 4 11.3% (n=13); р=0.05)); composite endpoint including lethal outcome + myocardial infarction + ACVE/TIA ((group 1 54.2% (n=13); group 2 15.4% (n=76); group 3 18.7% (n=90); group 4 31.3% (n=36); р1-2=0.0001; р1-3=0.0001; р1-4=0.005; р2-4=0.0006; р3-4=0.012)). Conclusion. Application of CEA demonstrated effectiveness and safety in the acute and early rehabilitation period of ACVE.

Background: Aortic coarctation is among the most common cardiovascular congenital abnormalities requiring repair after birth. Besides mortality, morbidity remains an important aspect. Accordingly, we reviewed our 20-year experience of aortic coarctation repair by thoracotomy, with emphasis on both short- and long-term outcomes. Methods: From 1995 through 2014, 214 patients underwent coarctation repair via left thoracotomy. Associated arch lesions were distal arch hypoplasia (n = 117) or type A interrupted aortic arch (n = 6). Eighty-four patients had isolated coarctation (group 1), 66 associated ventricular septal defect (group 2), and 64 associated complex cardiac lesions (group 3). Median follow-up was 8.4 years. Results: There was one (0.5%) procedure-related death. Nine (4.2%) patients died during index admission. In-hospital mortality was 0.7% in group 1 and 2 and 12.5% in group 3 ( P < .001). No patient had paraplegia. Actuarial five-year survival was 97.5% in group 1, 94% group 2 and 66% in group 3. Recurrent coarctation developed in 29 patients, all but four (1.8%) successfully treated by balloon dilatation. Freedom from reintervention (dilatation or surgery) at five years was 86%. At hospital discharge, 28 (13.5%) patients were hypertensive. At follow-up, hypertension was present in 11 (5.3%) patients. Conclusions: Long-term results of aortic coarctation repair by thoracotomy are excellent, with percutaneous angioplasty being the procedure of choice for recurrences. Patient prognosis is dependent on associated cardiac malformations. In this study, the prevalence of late arterial hypertension was lower than previously reported.

The objective of the study was to evaluate the long-term results of endoscopic papillosphincterotomy in cases of choledocholithiasis and papillary stenosis.Material and methods. We carried out retrospective analysis of the results of endoscopic papillosphincterotomy (EPST) due to the presence of choledocholithiasis (group 1, n=117) and papillary stenosis (group 2, n=55) along with the combination of the above (group 3, n=6) in a total of 178 patients. Clinical and endoscopic results of the intervention were studied in all patients in the long-term (from 1 to 30 years).Results. Based on the analysis of the complex examination, including endoscopic functional tests, treatment results were evaluated as good in 80 % of patients, satisfactory in 16 % of patients and unsatisfactory in 4 % of patients (after endoscopic correction of papillary stenosis).Conclusion. The cicatrisation process in the papillotomy opening exhibits the most intensively in patients with papillary stenosis combined with choledocholithiasis and without it, lasts until 4.5–5 years after surgery. Dynamic observation of patients after EPST is obligatory for early diagnosis of restenosis in the papillotomy opening.

Background: Fine needle aspiration biopsy (FNAB) is a simple, sensitive, quick and inexpensive method in which operator experience is essential for obtaining the best results. Methods: A descriptive study in which the aspiration biopsy cases of the Pathology and Cytopathology Service of the University Hospital of the UANL (2003–2005) were analyzed. These were divided into three study groups: Group 1, FNAB performed by a pathologist; Group 2, FNAB performed by specialists who are not pathologists, Group 3, FNAB guided by an imaging study with immediate evaluation by a pathologist. The samples were classified as adequate and inadequate for diagnosis, the organ, the size and characteristics of the lesions were taken into consideration. Results: A total of 1905 FNAB were included. In Group 1: 1347 were performed of which 1242 (92.2%) were adequate and 105 (7.7%) were inadequate. Of the 237 from Group 2, 178 were adequate (75.1%) and 59 inadequate (24.8%); in Group 3 there were 321 of which 283 (88.1%) were adequate and 38 (11.8%) inadequate. A statistically significant difference was found between FNAB performed by Group 1 (p< 0.001) and the other groups. A multivariate analysis was done where the organ punctured, the study groups, the size and characteristics of the lesion by study group were compared, finding that the most important variable was the person who performed the procedure. Conclusion: The experience and training of the person performing the aspiration biopsy, as well as immediate evaluation of the material when it is guided, substantially reduces the number of inadequate samples, improving the sensitivity of the method as well as reducing the need for open biopsies to reach a diagnosis.

Summary Aim: The goal of this study was to assess the accuracy and limitations of ultrasound guided fine-needle aspiration biopsy (ug-FNAB) of solitary thyroid nodules. Methods: The ug-FNAB results of 538 patients with solitary thyroid nodules, who afterwards underwent thyroid surgery, were compared retrospectively with the histology. Patients with multinodular goiter were excluded from the study. Ug-FNAB was performed on growing and/or hypoechoic and/or hypofunctional nodules. The ug-FNAB results were grouped as follows: group 1: malignant (n = 44); group 2: malignancy cannot be ruled out (n = 173); group 3: non-malignant (n = 296), group 4: inadequate (n = 25). Results: When the cytological results of group 1 and group 2 were interpreted os being malignant and those of group 3 as being benign, sensitivity, specificity and accuracy of ug-FNAB were 96.7%, 65.8% and 69.5% respectively. The 62 thyroid carcinomas (TO biopsied presented in 59 cases a suspicious or malignant cytology (95.2%). The smallest TC diagnosed by ug-FNAB had a diameter of 0.5cm and 36.4% of all papillary TC ≤ 1 cm displayed stage pT4. The histology verified a TC in 18 cases out of the 173 ug-FNABs in group 2. Non-malignant ug-FNABs were confirmed by histology in 294 patients (99.3%) in group 3. In 4.65% of the ug-FNABs inadequate material was aspirated. Conclusion: Nodules with non-suspicious ug-FNAB results can be safely followed-up by sonography, as the cytological diagnoses were verified in more than 99% by histology. Papillary TC can be diagnosed with ug-FNAB very accurately. As stage pT4 was present in more than one third of patients with papillary TC ≤ T cm, ug-FNAB is also recommended for thyroid nodules 0.5-1 cm in diameter located adjacent to the thyroid capsule. However, microfollicular proliferations remain the limitation of ug-FNAB, as the cytology cannot distinguish between benign adenoma and follicular TC.

Aim. To define the indications and to evaluate the effectiveness of various surgical treatment methods in patients with arterial stenosis and occlusion due to atherosclerotic vascular disease of lower extremities as a complication of diabetes mellitus. Methods. Results of surgical treatment of 52 randomly assigned patients who underwent surgeries due to peripheral vascular disease as a complication of diabetes mellitus (type 2 - 51 patients, type 1 - 1 patient) were analyzed. The following surgeries were performed: arterial reconstructive surgery - 24 (46.2%) patients (group 1), balloon catheter angioplasty and stenting - 12 (23.1%) patients (group 2), indirect revascularization surgery (revascularising osteotrepanation, endovascular prostaglandin E therapy) - 16 (30.7%) patients (group 3). Following parameters were assessed: decrease of ischemic rest pain, arterial insufficiency stage, hospitalization terms, healing of foot ulcers, mortality rate, and amputation rate. The longest foot ulcers healing terms [only in 5 patients (31.2%) at first year] were registered in the third group. 1 death was registered each in the first and in second groups (mortality rate 4.2 and 8.3% respectively), no deaths were registered in group 3. The results of trophic ulcers treatment in the patients from the third group were poor. It is tactically appropriate to prefer endovascular surgeries to open surgeries as far as in this case there is no need for local and general anesthesia allowing to decrease the number of complications and the length of rehabilitation together with comparable results. Primary open arterial reconstructive surgeries are possible in patients with diabetes mellitus as a next step after endovascular surgery or when endovascular surgery can not be done. Conclusion. Similar instant and long-term results were found after direct comparison of bypass and endovascular surgeries, allowing to recommend these surgeries in patients with peripheral vascular disease as a complication of diabetes mellitus.

Abstract OBJECTIVES Chronic kidney disease (CKD) is prevalent in patients undergoing cardiovascular surgery, and it negatively impacts procedural outcomes; however, its influence on the outcomes of aortic surgery has not been well studied. This study aims to elucidate the importance of CKD on the outcomes of aortic root replacement (ARR). METHODS Patients who underwent ARR between 2005 and 2019 were retrospectively reviewed (n = 882). Patients were divided into 3 groups based on the Kidney Disease: Improving Global Outcomes criteria: Group 1 [estimated glomerular filtration rate (eGFR) ≥ 60 ml/min/1.73 m2, n = 421); Group 2 (eGFR = 30–59 ml/min/1.73 m2, n = 424); and Group 3 (eGFR &lt; 30 ml/min/1.73 m2, n = 37). To reduce potential confounding, a propensity score matching was also performed between Group 1 and the combined group of Group 2 and Group 3. The primary end point was 10-year survival. Secondary end points were in-hospital mortality and perioperative morbidity. RESULTS Severe CKD patients presented with more advanced overall chronic and acute illnesses. Kaplan–Meier analysis showed a significant correlation between CKD stage and 10-year survival (log-rank P &lt; 0.001). The number of events for Group 1 was 15, Group 2 was 49 and Group 3 was 11 in 10 years. Group 3 had significantly higher in-hospital mortality (13.5% vs 3.5% in Group 2 vs 0.7% in Group 1, P &lt; 0.001) and stroke (8.1% vs 7.1% vs 1.2%, P &lt; 0.001) as well as introduction to new dialysis (27.0% vs 5.4% vs 1.7%, P &lt; 0.001). eGFR was shown to be an independent predictor of mortality (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99). Comparison between propensity matched groups showed similar postoperative outcomes, and eGFR was still identified as a predictor of mortality (hazard ratio, 0.97; 95% confidence interval, 0.95–0.99). CONCLUSIONS Higher stage in CKD negatively impacts the long-term survival in patients who are undergoing ARR.

The aim: To analyze and evaluate the efficacy of CDLLV treatment, using high-frequency endovascular welding (EVW), endovenous laser coagulation (EVLC) and catheter microfoam echosclerotherapy. Materials and methods: We have treated 329 patients with CDLLV C2-C6 functional classes according to the Clinical Etiological Anatomical Pathophysiology. Of these, 102 patients had vertical reflux eliminated by EVW, in 112 – by EVLC, and in 115 – by catheter microfoam echosclerotherapy. Results: In the EVW group 3 patients (2.94%) had a partial recanalization of coagulated veins 3 months after the procedure. In EVLC group 2 patients (1.79%) also had partial recanalization group after 6 months. In the group of catheter microfoam echosclerotherapy partial recanalization occurred in 3 patients during 3 months of observation, in the period of 6 months – in 2, in the period of 12 months – in 9, in total – in 14 patients (12.17%). The EVW and EVLC methods showed high efficacy of vertical reflux elimination on the great and small subcutaneous veins (GSV/SSV) in CDLLV and have no fundamental differences in the immediate and long-term results of treatment. Microfoam catheter echosclerotherapy leads to a greater number of recanalisations, compared with EVW and EVLC. Conclusions: High-frequency endovenous welding results in complete fibrotic GSV/SSV transformation in 97.06% of patients. Endovascular laser coagulation results in complete fibrotic GSV/SSV transformation in 98.21% of patients. Elimination of vertical reflux by microfoam echosclerotherapy results in complete fibrotic GSV/SSV transformation in 87.83% of patients.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Introduction: Preserved function of collecting duct is essential for the response to tolvaptan (TLV), and urinary level of aquaporin 2 (U-AQP2) can be a marker for vasopressin-dependent activity of collecting duct. Hypothesis: Higher levels of U-AQP2 in proportion to plasma levels of vasopressin (P-AVP) may be associated with better initial responses to TLV and eventually result in the improved prognosis after long-term treatment of TLV. Methods: Consecutive 60 in-hospital patients with stage D heart failure (HF) who received TLV on a de novo basis were enrolled during 2011-2013. We also selected 60 HF patients by propensity score matching who were hospitalized during the same period but never treated with TLV. Events were defined as death and/or HF re-hospitalization. Results: TLV (3.75-15 mg/day) was continuously administered except death or ventricular assist device implantation occurred. There were 41 patients (group 1) who had increases in UV over the first 24 h after TLV initiation, and all of them had U-AQP2/P-AVP ≥0.5 х103 with higher U-AQP2 levels (5.42 ± 3.54 ng/mL) before TLV treatment. On the other hand, UV rather decreased even after TLV initiation in 19 patients over the first 24 h (group 2). Those in the group 2 universally had U-AQP2/P-AVP <0.5 х103, extremely low U-AQP2 levels (0.76 ± 0.59 ng/mL, p<0.001 vs. group 1), and similar P-AVP with the group 1 at baseline. The 41 and 19 patients without TLV treatment (group 3 and 4) were respectively matched to the group 1 and 2 by propensity scores. Interestingly, every patient in the group 3 had U-AQP2/P-AVP ≥0.5 х103, and vice versa in the group 4. Among the four groups, congestion-related symptoms were only improved in the group 1 after 1 month of enrollment. The patients in the group 1 had significantly better event-free survival over 2-year by TLV treatment compared with the group 3 (76% vs. 43%, p<0.014). In contrast, the patients in the group 2 and 4 had very poor prognoses regardless of TLV treatment (7% vs. 11%, p=0.823). Conclusions: U-AQP2/P-AVP is a novel predictor for the initial response to TLV in HF patients. Patients with higher U-AQP2/P-AVP may enjoy a better prognosis by long-term TLV treatment probably due to efficient resolution of congestion.
