AtĂpusos aortacoarctatiĂłk sebĂ©szi kezelĂ©sĂ©nek hosszĂş távĂş eredmĂ©nyei
Absztrakt
Bevezetés: Az aortacoarctatio a leggyakoribb congenitalis
cardiovascularis elváltozások egyike, azok 5–8%-ában fordul elĹ‘. TĂpusos
elĹ‘fordulási helye az isthmicus szakasz. AtĂpusos helyen kialakulĂł coarctatio az
esetek mintegy 1%-ában fordul elő és többnyire súlyos hypertoniával szövődik.
Célkitűzés: A szerzők célul tűzték ki a kórkép sebészi
kezelési lehetőségeinek és azok hosszú távú eredményeinek ismertetését 27 beteg
műtéti kezelésével szerzett tapasztalataik alapján. Módszer: A
35 évet felölelő utánkövetés során a diagnosztika és a kezelési módszerek
változtak. Napjainkban a morfológiai diagnózis legáltalánosabb módszerei a
komputertomográfiás angiográfia és a mágneses rezonanciás angiográfia. Az
aortarekonstrukció lehetőségei az endovascularis technikák bevezetésével
gazdagodtak, de atĂpusos aortacoartatio esetĂ©ben a szerzĹ‘k ma is tĂşlnyomĂłan
változatos sebészi megoldásokat alkalmaznak. Eredmények: A
műtĂ©tek után nem veszĂtettek el beteget. A hypertonia minden esetben jelentĹ‘sen
csökkent. Gyermekkorban operált esetekben a növekedés okozta testméretváltozások
3 esetben újabb rekonstrukciós műtétet indokoltak.
KövetkeztetĂ©sek: Az atĂpusos aortacoarctatio individuális
sebészi módszerekkel eredményesen kezelhető. Gyermekkorban operált esetekben a
testmĂ©ret-növekedĂ©s a rekonstruált aortaszakasz revĂziĂłját teheti szĂĽksĂ©gessĂ©.

Mellkasiaortastentgraft-beültetések Magyarországon 2012 és 2016 között [Thoracic aortic stentgraft implantations in Hungary from 2012 to 2016]
Thoracic aortic endograft implantation has become a widespread procedure in recent years, yet no report is available about Hungarian outcomes. Examination of our results is crucial to define further treatment strategies. Analysis of perioperative data from Hungarian thoracic endograft implantations based on the experience of 5 years is presented. Our retrospective, multicentric study analysed voluntarily reported data from all Hungarian institutions where thoracic endograft implantations are performed. Information was collected from every procedure performed in 5 years. Between 2012 and 2016, 131 thoracic stent graft implantations were performed in Hungary (67.18% male, mean age 62.80 years). 25.19% of the procedures were acute. 13.74% of the patients were diabetic. Indications for the procedure were aneurysm (64.89%), dissection (17.56%), aortic trauma (6.87%) and other conditions (10.69%). 73.91% of the dissection cases were acute. 16.47% of repaired aneurysms were ruptured. Additional preoperative revascularization (debranching) was performed in 26.72% of the cases. Postoperative stroke occured in 4.58%, temporary hemodialysis was needed in 1.53%, bowel ischaemia was present in 2.29% and reoperation within 30 days was needed in 5.34% of all cases. Thirty-day mortality of the procedure was 9.92%, 5-year long-term mortality reached 16.03%. Endovascular repair of the thoracic aorta is an effective procedure and our national data comfirmed its advantages compared to open thoracic surgery. Further use of the procedure in Hungary depends on the centralised care in vascular surgery and financial matters. Multidisciplinary cooperation and proper logistics are needed to provide patients with optimal treatment. Orv Hetil. 2018; 159(2): 53-57
Factor V Leiden and apolipoprotein E genotypes in severe femoropopliteal atherosclerosis with restenosis
Observation of an exotic narrow doubly charmed tetraquark
Conventional, hadronic matter consists of baryons and mesons made of three quarks and a quark-antiquark pair, respectively(1,2). Here, we report the observation of a hadronic state containing four quarks in the Large Hadron Collider beauty experiment. This so-called tetraquark contains two charm quarks, a (u) over bar and a (d) over tilde quark. This exotic state has a mass of approximately 3,875 MeV and manifests as a narrow peak in the mass spectrum of (DD0)-D-0 pi(+) mesons just below the D*D-+(0) mass threshold. The near-threshold mass together with the narrow width reveals the resonance nature of the state
