    Abstract BACKGROUND: The literature does not support the choice between open and laparoscopic management of splenic artery aneurysms (SAA). METHODS: We designed a prospective, randomized comparison between open and laparoscopic surgery for SAA. Primary end points were types of surgical procedures performed and clinical outcomes. Analysis was developed on an intention-to-treat basis. RESULTS: Fourteen patients were allocated to laparotomy (group A) and 15 to laparoscopy (group B). Groups displayed similar patient- and aneurysm-related characteristics. The conversion rate to open surgery was 13.3 %. The type of surgical procedure performed on the splenic artery was similar in the two groups: aneurysmectomy with splenic artery ligature or direct anastomosis was performed in 51 % and 21 % of patients in group A and in 60 % and 20 % in group B, respectively. The splenectomy rate was similar (14 % vs. 20 %). Postoperative splenic infarction was observed in one case in each group. Laparoscopy was associated with shorter procedures (p = 0.0003) and lower morbidity (25 % vs. 64 %, p = 0.045). Major morbidity requiring interventional procedures and blood transfusion was observed only in group A. Laparoscopy was associated with quicker resumption of oral diet (p < 0.001), earlier drain removal (p = 0.046), and shorter hospital stay (p < 0.01). During a mean follow-up of 50 months, two patients in group A required hospital readmission. In group B, two patients developed a late thrombosis of arterial anastomoses. CONCLUSIONS: Our study demonstrates that laparoscopy permits multiple technical options, does not increase the splenectomy rate, and reduces postoperative complications. It confirms the supposed clinical benefits of laparoscopy when ablative procedures are required but laparoscopic anastomoses show poor long-term results

    Tämän opinnäytetyön tavoitteena oli selvittää, miten Finavian ylläpitämällä Helsinki-Vantaa lentoasemalla tapahtuvat häiriö- ja poikkeamatilanteet vaikuttavat lentoasemalla toimiviin Finavian omiin organisaatioihin sekä lentoasemalla toimiviin viranomaisiin. Häiriö- ja poikkeamatilanteella tarkoitetaan lentoaseman normaaliin toimintaan häiritsevästi vaikuttavaa tapahtumaa, esimerkiksi sähkökatkoa. Työ tehtiin Helsinki-Vantaa lentoaseman tilannekuvakeskuksen päällikön pyynnöstä. Tilannekuvakeskuksessa huomattiin, että vaikka häiriö- ja poikkeamatilanteessa toiminta eri tahojen kanssa on ollut kitkatonta ja sujuvaa, ei toisen organisaation sisällä tapahtuvasta toiminnasta ollut kuvaa. Työn avulla selvitettiin, onko häiriö- tai poikkeamatilanteella vaikutusta eri organisaatioiden ja viranomaisten toimintaan. Opinnäytetyö auttaa rakentamaan kokonaiskäsitystä poikkeamatilanteiden aiheuttamasta toiminnasta koko lentoaseman alueella. Tätä kautta voidaan myös lisätä ymmärrystä eri organisaatioiden ja viranomaisten välillä. Opinnäytetyö toteutettiin yhteistyössä Helsinki-Vantaa lentoaseman tilannekuvakeskuksen kanssa. Työn edetessä rakennetta muokattiin yhteistyössä tilaajan kanssa niin, että se palvelisi mahdollisimman tarkoituksenmukaisesti eri organisaatioita. Työ toteutettiin tekemällä laadullinen tutkimus, jonka runkona oli puolistrukturoitu haastattelu. Haastatteluita kertyi yhteensä 19 kappaletta ja haastateltavia 21. Haastateltavina olivat Finavian eri organisaatioiden johtajia tai päälliköitä ja lentoaseman toimintaan liittyvien viranomaisten lentoaseman toimipisteiden päälliköt. Työstä rajattiin pois kaupalliset yritykset, koska haastatteluiden määrä olisi kasvanut liian suureksi. Lentoaseman tilannekuvakeskus on luonut useita valmiita toimintamalleja erilaisiin häiriö- ja poikkeamatilanteisiin. Tilannekuvakeskuksen päällikkö valitsi näistä häiriö- ja poikkeamatilanteista ne, jotka ovat todennäköisiä tai merkittäviä ja vaikuttavat haitallisesti lentoaseman toimintaan. Erilaisia häiriö- ja poikkeamatilanteita valikoitui 17 kappaletta. Näiden tilanteiden vaikutuksia ja toimintamalleja käsiteltiin haastatteluissa. Haastatteluissa saatu informaatio liitettiin tilannekuvakeskuksen toimintamalleihin ja luotiin jokaiseen valittuun poikkeamatilanteeseen kronologinen kuvaus eri organisaatioiden toiminnasta. Opinnäytetyöstä on myöhemmin tarkoitus tehdä pelkistetympi käsikirja Finavian ja viranomaisten käyttöön.The aim of this study was to find out how to Finavia’s Helsinki-Vantaa airport take place in crisis and emergency situations and how they affecting operating at the airport Finavia's own organizations as well as authorities operating at the airport. The work was done at the request of the Head of the Helsinki-Vantaa airport operation center. The airport operation center noted that although the crisis and emergency situations operation with various parties has been smooth, but nobody didn’t have a picture how these crisis and emergency situations was handled in the another organizations. The work purpose was to find out whether the fault or deviation situation could affect the functioning of the various organizations and public authorities. The thesis helps to build the overall understanding of the actions caused by the deviation of situations throughout the airport. This period may also increase the understanding of the different organizations and authorities. The research was conducted in cooperation with the Helsinki-Vantaa airport operation center. As work progresses, the structure was modified in cooperation with the client so that it would serve as appropriately as possible the different organizations. The work was carried out by qualitative research, whose backbone was the semi-structured interview. Interviews were a total of 19 tracks and 21 interviewees were interviewed leaders or managers in different organizations and Finavia's airport activities related to airport authorities, heads of offices. Work were excluded trading companies, because the number of interviews had grown too large. The airport operation center has created a number of ready-made models for different crisis and emergency situations. Head of the Centre chose a snapshot of the crisis and emergency situations, those who are likely or significant and adversely affect the operation of the airport. 17 various types of crisis and emergency situations was selected. Effects and models of these situations addressed in the interviews. The information obtained in the interviews attached a airport operation center’s operational models and was created for each selected deviation situation chronological description of the activities of various organizations. The thesis is later to be made simpler manual for use by Finavia and the authorities

    The utilization of cardiovascular rehabilitation (CR) programmes in patients with Lower Extremity Peripheral Artery Disease (LEPAD) is generally poor, with limited evidence of current policies for referral. The aim of the study was to evaluate, within a cohesive network of CR and vascular surgery facilities with facilitated referral process, the clinical characteristic of LEPAD patients referred to CR and related outcomes, as compared to patients not referred. The present is an observational prospective study of consecutive patients recruited at vascular surgery facilities. Out of 329 patients observed, the average referral rate to CR was 34% (28% and 39% in patients with and without recent peripheral revascularization, p<0.05). LEPAD patients entering the CR programme were similar to those who did not according to sex, age, the vascular surgery setting of evaluation, and localization of arterial lesions. Patients with moderate intermittent claudication and patients with acute limb ischemia as index event were more represented among those who attended CR (41% vs 21% and 9% vs 2% respectively, p<0.05). Patients referred to CR had five times more episodes of acute coronary syndrome and heart failure as complication of the index event. The cardiovascular risk profile (obesity 29.5% vs 11%, p<0.05; hypercholesterolemia 80% vs 61%, p<0.05) was much worse in LEPAD patients referred to CR, but conversely, they better achieved secondary prevention targets, particularly for blood pressure control (97% vs 57%, p<0.05). All-cause 2-year mortality in the whole patients' population was 6%. Patients entering the CR programme displayed less events (13.5% vs 37.7%, p<0.05), mainly death (3.1% vs 11.3%, p<0.05) and limb-related events (4.2% vs 15.2%, p<0.05). The results of our study suggest that when a cohesive network of vascular surgery and CR facilities becomes available, the referral rate to rehabilitation may increase up to one third of eligible patients. Patients with higher comorbidity and cardiovascular risk seem to have priority in the referral process, nevertheless those with peripheral revascularization are still underestimated. Entering CR may ensure better cardiovascular risk profile and cardiovascular prognosis in LEPAD patients, and consequently the systematic adoption of this care model needs to be strongly recommended and facilitated

    Background We report the results of the operative treatment for type 2 endoleak (T2E) involving the inferior mesenteric artery (IMA) using the transarterial embolization (TAE) or the video laparoscopic ligation (VLS). Methods Between January 2005 and December 2015, we retrospectively analyzed 901 patients treated with endovascular aortic repair (EVAR): 883 (98%) had 1 valid postoperative radiologic evaluation, at least. All patients with operative repair for IMA-related T2E entered the final analysis. Indication of their operative repair was sac enlargement (>5 mm within 6 months or >1 cm from the preoperative diameter, irrespectively of the postoperational time) and/or its persistence >12 months. Results We detected 192 (21.7%) T2Es, overall. We identified 37 (4.2%) IMA-related T2Es, and treated 21 cases (VLS n = 11, TAE n = 10). Aneurysm-related mortality and major or minor morbidity was never observed. Time of intervention did not differ significantly (minutes, VLS = 97 ± 46 vs. TAE = 95 ± 21, P = 0.901). Hospitalization was significantly lower in the TAE group (days, 4 ± 2 vs. 1 ± 0.4, P < 0.001). No patient was lost at a mean follow-up of 46 ± 32 months (range, 1–110; median, 48). At last follow-up, sac diameter was significantly more stable in the VLS (mm, 60 ± 10 vs. 55 ± 7, P = 0.593) than that in the TAE group (mm, 57 ± 9 vs. 63 ± 10, P = 0.050). The IMA-related T2E reintervention rate was not significantly different between the groups (VLS, n = 0 [0%] vs. TAE, n = 2 [20.0%], P = 0.213). Secondary aortic reintervention rate was 28.6% (n = 6), and secondary open conversion rate was 9.5% (VLS, n = 1 [9.1%] vs. TAE, n = 1 [10.0%], P = 1). Conclusions In authors' experience, operative treatment of IMA-related T2E was safe; VLS proved to be effective and durable in sealing this type of T2E. Patients receiving correction of IMA-related T2E after EVAR remained at risk for development of any type of endoleaks, as well as at risk of reintervention
