Atherosclerotic lesions of the supra-aortic arteries are mainly localized in the carotid artery bifurcations – 57%, the subclavian artery – 18%, the vertebral arteries – 14%, the brachiocephalic trunk and the common carotid artery – 11%.Objective. Theobjective of the research was to systematize the principles of surgical treatment of patients with atherosclerotic lesions of the supra-aortic arteries taking into consideration their polymorbidity and the multicentricity of atherosclerosis.Materials and methods. The results of surgical reconstruction of the supra-aortic arteries in 468 patients were analyzed.All the patients were divided into two groups.Group I included 276 (59%) patients with previous surgical or endovascular intervention on any vascular territory for treatment of atherosclerotic lesions being admitted to the hospital for elective surgery on the extracranial arteries.Group II included 192 (41%) patients without previous surgical and invasive treatments of arterial pathology being hospitalized for surgery on the supra-aortic arteries.Results. In Group I, according to the objective and clinical methods of examination, the patients’ condition was more critical due to somatic and intraoperative risk. When analyzing the results of postoperative complications there was no statistically significant difference between both groups (p<0.05).The overall rate for serious complications (acute cerebrovascular disease and myocardial infarction) in both groups was 3.4%; the mortality rate was 1.1%.Conclusions. 1. Approximately 87% of surgical reconstructions of the aortic arch branches are aimed at the prevention of acute cerebrovascular disease. 2. Surgical treatment of atherosclerotic lesions of the supra-aortic arteries allows us to achieve good postoperative results (the overall rate for serious complications – 3.4%, the mortality rate –1.1%).

CONTEXT: The performance of each ICU needs to be assessed within the overall context of medical care, as well as by the institution which the ICU forms part of. Evaluation mechanisms in the field of intensive care have been developed that are recognized worldwide within the scientific literature. OBJECTIVE: To study outcomes from groups of critical patients and to compare their actual and estimated mortality rates. DESIGN: Prospective study of patients' outcomes. SETTING: A tertiary care unit for a period of 13 months (anesthesiology intensive care unit at the Escola Paulista de Medicina). PARTICIPANTS: 520 patients selected according to sex, age and nature of hospitalization. DIAGNOSTIC TEST: The modified APACHE II prognostic index was applied in order to assess clinical severity and anticipation of mortality in three groups who had non-surgical treatment, emergency surgery and elective surgery. MAIN MEASUREMENTS: The APACHE II index. RESULTS: The application of this index allowed patients to be stratified and expected death risks for both subgroups and the entire sample population to be calculated. The observed mortality rate was greater than the expected rate (28.5% versus 23.6%, respectively), with a statistically significant difference. The standardized mortality rate was 1.20. Patients who obtained scores above 25 presented a significant outcome towards death. The most severe and worst evolving cases were, in decreasing order: non-surgical, emergency surgical and scheduled surgical patients; the actual general mortality rate was higher than the expected one. CONCLUSIONS: The use of the APACHE II index made it possible to stratify critical patient groups according to the severity of their condition.

Background/Aim. A modern approach to surgical treatment of tuboperitoneal infertility is based on laporascopic techniques. The aim of this study was to compare results of tuboperitoneal infertility treatment by the use of laparoscopy and classical laparotomy. Methods. A retrospectiveprospective study on 66 women treated operatively form tuboperitoneal infertility was performed. Data from patient's anamnesis and those related to the surgical treatment results, obtained by the use of an inquiry, were used in retrospective and prospective analysis, respectively. Chi-square test was used in statistical analysis. P value < 0.05 was considered significant. Results. Classical laparotomy was used on 34 women in a period from 1996 to 1997, while 32 women were operated laparoscopically in a period from 1999 to 2000. The results were as follows: a total number of conceived women was 16 (24%), seven in the group I (20.6%) and nine in the group II (28.1%); 13 women were with one pregnancy, six in the group I (17.6%) and seven in the group II (22%). Twice pregnant were three women, one in the group I (2.9%) and two in the group II (6.2%). The resulting pregnancies were: five women with abortion spontaneous, two in the group I (5.9%) and three in the group II (9.4%); two women with extrauterine pregnancy in the group I (5.9%); three with pretemporal birth, one in the group I (2.9%) and two in the group II (6.2%), while six women were with the temporal birth, two in the group I (5.9%) and four in the group II (12.5%). Statistical analysis showed that there was no significant difference in the results between these two groups. Conclusion. Surgical treatment of tubeperitoneal infertility, regardless of the used methods (classical laparotomy or laparoscopy) was successful in a great number of women. These methods have a great advantage over in vitro fertilization, and they should not be ignored.

Past experience with open and closed techniques of tympanoplasty in surgery of cholesteatoma has shown that recurring illness is one of the major causes of surgical failure. The literature has reported varying trend of surgical treatment of cholesteatoma. The objective of the study was to analyze the significance of surgical technique in relation to the incidence and most frequent localization of recurrent cholesteatoma. Our study analyzed 120 patients operated on for cholesteatoma. The patients were divided into two groups, group I (45) with recurring disease and group II (75) without any recurring condition, which were followed up three years. Statistical analysis was carried out by modified t-test. The largest number of patients was re-operated in the first two years from the initial surgery (50%), In the majority of patients (50%), recurrent cholesteatoma was most commonly localized (stage I) in attic (20%) and much rarely in mesotympanum (11,9%). Stage III recurrent cholesteatoma was verified in 35% of patients, most frequently diffuse form (13,4%). The involvement of attic by all three stages of disease accounted for over 60%. The analysis of the used techniques of surgical treatment in both groups revealed significant difference. Open techniques of tympanoplasty were used in 60% of patients with no recurrence. Closed techniques were used more frequently in patients with recurring disease, i.e. in over 90% of cases. Recurrent cholesteatoma develops, in the majority of cases, during the first two years after the surgical intervention. Attic is the most common localization of cholesteatoma. More frequent utilization of open technique of tympanoplasty for surgery of cholesteatoma significantly reduces the incidence of recurring condition. The indications for CWD technique are the initial spread of cholesteatoma, possibility of complete removal of cholesteatoma and postoperative follow-up of patients.

Objective. Descending necrotizing mediastinitis (DNM) is a serious form of mediastinitis with a high mortality rate. It is caused by the downward spread of an oropharyngeal or cervicofascial infection. The optimal surgical approach for this often fatal disease is controversial. This article describes the authors’ experience and characterizes the surgical strategies and treatment outcomes of patients with DNM. Study Design. Case series with chart review. Setting. A tertiary referral medical center. Subjects and Methods. This study conducted a retrospective chart review of patients with deep neck infections treated at a medical center from 1994 to 2007 and identified 29 patients with DNM. The clinical characteristics and outcomes were compared between patients treated with transcervical drainage alone (group I) and those with both cervical and thoracic drainage (group II). Results. There were 20 patients in group I and 9 patients in group II. The overall mortality rate was 10.3%. The mean duration of the hospital stay was 29.3 ± 15.5 days. There was no statistically significant difference in age, sex distribution, or duration from the appearance of symptoms to hospital admission between the 2 groups. The duration of hospital stay, tracheotomy rate, and mortality rate also did not differ significantly between the 2 groups. However, the numbers of surgeries were significantly higher in group II than in group I. Conclusion. Transthoracic mediastinal drainage is not a compulsory therapy, but timely, aggressive, transcervical mediastinal drainage with extensive debridement is very important for a good outcome when treating DNM patients.

Optimalus vidinės miego arterijos endarterektomijos laikas sergant smegenų insultu ir didelio laipsnio vidinės miego arterijos stenoze Auksė Meškauskienė, Egidijus Barkauskas, Artūras MackevičiusVilniaus universiteto Neurologijos ir neurochirurgijos klinikosNeuroangiochirurgijos centras,Šiltnamių g. 26, LT-04130 VilniusEl paštas: [email protected] Įvadas / tikslas Miego arterijos endarterektomija yra veiksmingas gydymo būdas, padedantis išvengti insulto esant didelio laipsnio simptominei miego arterijos stenozei. Ankstyva, tuoj po insulto atlikta endarterektomija sukelia daug komplikacijų, todėl dauguma chirurgų siūlo operaciją atidėti 4–6 savaitėms. Tačiau operacijos atidėjimas didina insulto pasikartojimo riziką. Naujausios literatūros duomenimis, per 30 dienų nuo insulto pradžios atlikta endarterektomija nedidina komplikacijų skaičiaus, tačiau nėra vienodos nuomonės dėl tikslaus operacijos laiko. Darbo tikslas – nustatyti operacijos riziką ligoniams, kurie serga smegenų insultu ir didelio laipsnio vidinės miego arterijos stenoze, atsižvelgiant į atliekamos endarterektomijos laiką. Ligoniai ir metodai Į analizę įtraukti duomenys 243 ligonių (192 vyrų ir 51 moters, amžiaus vidurkis 65,4 metų), kurie sirgo išeminiu insultu ir jiems buvo operuota simptominė didelio laipsnio miego arterijos stenozė. Iki operacijos visų analizuotų ligonių neurologinė simptomatika buvo stabili arba gerėjanti. Atsižvelgdami į laiko trukmę nuo ligos pradžios iki operacijos, ligonius suskirstėme į keturias grupes: I grupę (n = 59) sudarė operuotieji pirmą savaitę, II grupę (n = 61) – antrą savaitę, III grupę (n = 67) trečią ar ketvirtą savaitę, IV grupę (n = 56) – po keturių savaičių nuo ligos pradžios. Rezultatai Po operacijos komplikacijų buvo 14 (5,6%) ligonių, pusei iš jų įvyko insultas ir tiek pat ligonių mirė. Komplikacijų pasireiškė 5 ir 59 (8,5%) pirmos grupės ligonių, 4 iš 61 (6,5%) – antros, 1 iš 67 (1,5%) – trečios ir 4 iš 56 (7,2%) – ketvirtos. Mažiausia komplikacijų ištiko ligonius, kuriems endarterektomija daryta trečią ar ketvirtą ligos savaitę, nors komplikacijų skirtumas tarp grupių nebuvo statistiškai reikšmingas. Išvados Mirties ir operacinio insulto rizika ligoniams, sergantiems insultu ir didelio laipsnio vidinės miego arterijos stenoze, tiesiogiai nepriklausė nuo endarterektomijos laiko, tačiau mažiausiai komplikacijų ištiko ligonius, operuotus trečią ar ketvirtą savaitę nuo insulto pradžios. Reikšminiai žodžiai: insultas, miego arterijos endarterektomija, laikas, operacinė rizika The optimal timing of carotid endarterectomy in patients with stroke and severe carotid artery stenosis Auksė Meškauskienė, Egidijus Barkauskas, Artūras MackevičiusVilnius University, Clinics of Neurology and Neurosurgery,Center of Neuroangiosurgery,Šiltnamių str. 26, LT-04130 Vilnius, LithuaniaE-mail: [email protected] Background / objective Carotid endarterectomy is highly effective in preventing stroke in patients with recentl symptomatic severe stenosis. Some studies showed early carotid endarterectomy to carry a high risk. Therefore, many surgeons delay carotid endarterectomy for 4 to 6 weeks after stroke, but any delay leads to reduced benefit because of the risk of stroke before surgery. Recent data have suggested that the operative risk is not increased in patients operated on within 30 days of stroke; however, controversy remains regarding the timing of this intervention. The purpose of the current work was to determine the operative risk of death and stroke in patients with stroke and severe carotid stenosis in relation to the time of carotid endarterectomy. Patients and methods A retrospective study of 243 patients undergoing carotid endarterectomy after stroke is presented. All patients had either stable or improving neurological examinations. The patients were divided into four groups: group I (n = 59) patients who had carotid endarterectomy between 2–7 days after stroke, group II (n = 61) patients who had carotid endarterectomy during the second week, group III (n = 67) patients who were operated during the third–fourth week after stroke and group IV (n = 56) patients who were operated on later than 4 weeks. Results Of the 192 men and 51 women who underwent surgery, there were 7 strokes and 7 deaths, with the total rate of complications 5.6%. Postoperative stroke and mortality was respectively: group I – 8.5%, group II – 6.5%, group III – 1.5%, group IV – 7.2%. There was no statistically significant difference in operative risk among the groups; however, a trend toward a decreased operative risk was noticed in patients operated on during the third–fourth week after stroke. Division to early (<2 weeks) and late (>2 weeks) endarterectomy also did not reveal any significant difference in the operative risk. Conclusions The perioperative risk of stroke and death was unrelated to the timing of carotid endarterectomy in patients with stroke and severe carotid stenosis. Carotid endarterectomy can be performed safely after 2 weeks of ischemic stroke in patients with severe carotid artery stenosis. Key words: stroke, carotid endarterectomy, time, operative risk

Introduction. It has been established that infrainguinal occlusive disease, type III peripheral obliterative arterial disease (POAD), is more common in diabetics than in non-diabetics. It is presumeable that after surgical treatment of this arterial segment diabetics develop more complications and higher mortality rate than nondiabetics. The aim of this study was to analyze the results of reconstructive surgical treatment of diabetic and non-diabetic patients with type III PAOD. Material and Methods. In the period 1999-2003, 118 patients with Type III PAOD underwent surgery at the Vascular Surgery Clinic in Novi Sad. They were divided into two groups: group I included 51 nondiabetic patients, and group II 67 diabetic patients. Subgroups were formed based on the clinical status. Differences were established in IVa, (46 diabetics and 4 non-diabetics) and IVb stage (11 diabetic and 30 non-diabetic patients). Results. Statistical data analysis using X2 test showed a statistical difference in complications rates, number of salvaged limbs and finally, in the mortality rates between diabetic and non-diabetic patients. Conclusion. Diabetic patients presented with significantly more trophic skin lesions (IVa stage). The overall complication rate was significantly higher in diabetics, as well as the amputation rate. Finally, the mortality rate was also significantly higher in diabetics than in nondiabetic patients. .

Aim:  Our aim in conducting this study was to ascertain the clinical, pathological, and radiological characteristics of patients diagnosed with idiopathic granulomatous mastitis in our clinic and to contribute to related literature by creating a therapy algorithm for granulomatous mastitis. Method: A total of 62 patients diagnosed with granulomatous mastitis in our clinic were classified into three groups as per the mode of treatment they received. Among these, 20 patients who had only been administered corticosteroids were allocated to Group I, while 18 patients who had received surgical treatment in addition to corticosteroid treatment were allocated to Group II, and 24 patients who had only received surgery were allocated to Group III. Results: All the cases were female patients. The mean age of the patients was 33.67 ± 6.35 (21-48). No statistically significant difference was found among the groups as per the mean age figures, pregnancy, breastfeeding, oral contraceptive administration, smoking and alcohol use, and family history (p>0.05). 49 (77.4%) patients were diagnosed with granulomatous mastitis by thick-needle biopsy, 7 (11.2%) by incisional biopsy, 4 (6.4%) by excisional biopsy, and 3 (4.8%) by fine-needle aspiration biopsy (FNAB) before the onset of treatment. The median value for the follow-up of the patients was 40 (6-81) months and there was no statistically significant difference among follow-up periods (p: 0.51). 15 (24.1%) patients among all the cases had recurrence. There was a statistically significant difference among the groups with regards to recurrence (p: 0.015). Conclusion:  Granulomatous mastitis may simulate breast cancer both clinically and radiologically. Recurrence is observed in patients who only received corticosteroid or surgical treatment. The combination of corticosteroid and surgical treatment significantly reduces the rate of recurrence. Therefore, this combination can be recommended as selective treatment.

OBJECTIVEParasellar growth is one of the most important prognostic variables of pituitary adenoma surgery, with adenomas regarded as not completely resectable if they invade the cavernous sinus (CS) but potentially curable if they displace CS structures. This study was conducted to correlate surgical treatment options and outcomes to the different biological behaviors (invasion vs displacement) of adenomas with parasellar extension into the superior or inferior CS compartments or completely encasing the carotid artery (Knosp high grades 3A, 3B, and 4).METHODSThis was a retrospective cohort analysis of 106 consecutive patients with Knosp high-grade pituitary adenomas with parasellar extension who underwent surgery via a primary endoscopic transsphenoidal approach between 2003 and 2017. Biological tumor characteristics (surgical status of invasiveness and tumor texture, 2017 WHO classification, proliferation rate), extent of resection, and complication rate were correlated with parasellar extension grades 3A, 3B, and 4 on preoperative MRI studies.RESULTSInvasiveness was significantly less common in grade 3A (44%) than in grade 3B (72%, p = 0.037) and grade 4 (100%, p < 0.001) adenomas. Fibrous tumor texture was significantly more common in grade 4 (52%) compared to grade 3A (20%, p = 0.002), but not compared to grade 3B (28%) adenomas. Functioning macroadenomas had a significantly higher rate of invasiveness than nonfunctioning adenomas (91% vs 55%, p = 0.002). Mean proliferation rate assessed by MIB-1 was > 3% in all groups but without significant difference between the groups (grade 3A, 3.2%; 3B, 3.9%; 4, 3.7%). Rates of endocrine remission/gross-total resection were significantly higher in grade 3A (64%) than in grade 3B (33%, p = 0.021) and grade 4 (0%, p < 0.001) adenomas. In terms of complication rates, no significant difference was observed between grades.CONCLUSIONSAccording to the authors’ data, the biological behavior of pituitary adenomas varies significantly between parasellar extension patterns. Adenomas with extension into the superior CS compartment have a lower rate of invasive growth than adenomas extending into the inferior CS compartment or encasing the carotid artery. Consequently, a significantly higher rate of remission can be achieved in grade 3A than in grade 3B and grade 4 adenomas. Therefore, the distinction into grades 3A, 3B, and 4 is of importance for prediction of adenoma invasion and surgical treatment considerations.

BACKGROUND: Complications from abdominal surgery may necessitate a second or more surgeries, re-laparotomy. It is associated with significant morbidity and mortality. Data on relaparotomy from the developing nations is limited. This study aims to assess the indications and outcome of patients who had relaparotomyMETHODS: A retrospective review of medical records of all patients who underwent Re-laparotomy at St. Paul’s Hospital Millennium Medical College from January 2016 to December 2017 was done.RESULT: Of 2146 laparotomies, 6.9% (149) needed re-laparotomy and 129 patients were analyzed. Most (123,95.3%) had on-demand re-laparotomy. Patients operated on emergency made 70.5% (91) of the cases making the ratio of emergency to elective surgery 2.4:1. The three most common surgeries that needed re-laparotomy were, Perforated appendicitis (35,27.1%), bowel obstructions (28,21.7%) , and trauma (20,13.4%). The most common indications for relaparotomy were intra-abdominal abscess (57,44.23%), wound dehiscence (17,13.2%) and anastomotic leak (15 ,11.6%). Surgical site infection (128,100%) and malnutrition (58,45%) were the leading complications. The overall mortality rate was 12.8 % (19). There was no statically significant difference in mortality rate between on-demand and planned re-laparotomy (P=0.388), urgency of the primary surgery (P=0.891) and the number of relaparotomy (p=0.629). Re-laparotomy for anastomotic leak(p=0.001) and patients above fifty years of age (P=0.015) had significant associations with mortality.CONCLUSION: Intra-abdominal abscess collection, wound dehiscence and anastomotic leak were the most common indications of re-laparotomies. Age above fifty years and anastomotic leaks were significantly associated with mortality
