Az arteria anonyma szűkületeinek minimálisan invazív, endovascularis terápiája sikeres és biztonságos = Percutaneous, endovascular treatment of innominate artery lesions is a safe and effective procedure

Az arteriaanonyma-stenosisok kezelésében az intervenciós radiológia (ballonkatéteres tágítás, illetve stentbeültetés) beavatkozásai kerültek túlsúlyba a sebészi terápia helyett. A szerzők az anonymaszűkületek kezelése során nyert tapasztalataikat mutatják be az olvasóközönségnek. A nemzetközi irodalomban fellelhető két legnagyobb esetszámú retrospektív analízisük beteganyagából emelnek ki két beteget, akik példáján az arteriaanonyma-laesiók kivizsgálását, kezelését, majd utánkövetését illusztrálják. A megbeszélésben pedig részletes irodalmi áttekintéssel támasztják alá e kezelés eredményességét és biztonságosságát. A 74 éves dohányzó férfi beteg hypertonia, hypercholesterinaemia és alsó végtagi claudicatio korábbi diagnózisaival, szédüléssel és felső végtagi claudicatióval jelentkezett. Kivizsgálása során 30 Hgmm felső végtagi vérnyomáskülönbség, a carotis-Doppler-ultrahangon szignifikáns stenosisra utaló poststenoticus nyomásgörbe, az arteria vertebralisban retrográd áramlás volt kimutatható. Diagnosztikus angiográfia során 80%-os stenosist igazoltak az arteria anonymán, amit egy ülésben primer ballonkatéteres tágítással és stentbeültetéssel oldottak meg. A beteg öt hónapos utánkövetése során neurológiai komplikáció vagy szignifikáns restenosis nem igazolódott. A második beteg 59 éves, szintén dohányzó nőbeteg volt, aki ismert hypertoniában és 2-es típusú diabetes mellitusban szenvedett. A beteg jobb felső végtagi zsibbadással jelentkezett kivizsgálásra, amely során szubokkluzív arteriaanonyma-szűkület igazolódott. A diagnosztikus angiográfiát megelőző fizikális vizsgálat a jobb felső végtagon radialis pulzus hiányát igazolta, egyidejűleg az arteria carotis communisban proximalis, szignifikáns szűkületre utaló nyomásgörbe volt fellelhető. Primer ballontágítást követően a beteg 15 hónapos utánkövetési idő után is panasz- és tünetmentes, preoperatív tünetei nem tértek vissza, új neurológiai tünetek nem alakultak ki. Az esettanulmány két betegen illusztrálja a szerzők nagy esetszámú retrospektív tanulmányaik során nyert tapasztalatait, melyek szerint a transfemoralis arteriaanonyma-intervenció stentbeültetéssel vagy a nélkül jó sikerrátájú, biztonságos, napjainkban elsődlegesen választandó terápiás beavatkozás. Az irodalmi áttekintés adatai megerősítik, hogy az a. anonyma intervenciós radiológiai kezelése, ballonos tágítása, illetve stentelése eredményes és biztonságos. Orv. Hetil., 2011, 152, 1745–1750. | Percutaneous endovascular treatment (transluminar balloon angioplasty with or without stent implantation) of innominate artery lesions has become the treatment of choice prior to surgery in the past decades. Authors present the diagnostics, treatment and follow-up of two patients as examples from their largest series in the literature. A 74-year-old male patient with a history of hyperlipidemia, hypertension, nicotine abuse and lower limb claudication was admitted because of acute upper limb claudication and dizziness. Physical examination revealed blood pressure difference of 30 mmHg between his arms, and poststenotic flow pattern in the common carotid artery with retrograde flow in the vertebral artery on carotid duplex scan. Diagnostic angiography showed 80% stenosis of the innominate artery, which was treated with percutaneous transluminar balloon angioplasty with stent implantation. Follow-up examination at 5 months showed no significant restenosis or neurological complication. The second patient was a 59-year-old smoker female patient with hypertension and type 2 diabetes mellitus, who was evaluated for her upper limb claudication. Initial finding was the absence of radial pulse in the right side. Color duplex scan revealed proximal subocclusion, which was confirmed by angiography. In one stage, balloon angioplasty was made, with immediate pain relief. After 15 months the patient was symptom-free. These two cases demonstrate an excellent outcome of endovascular treatment of innominate artery lesions, as authors already reported in two retrospective studies. Balloon angioplasty with, or without stent deployment appears to be a safe procedure with excellent primary success rate. Review of international studies also indicates that endovascular therapy of the innominate artery is safe and effective. Orv. Hetil., 2011, 152, 1745–1750

Transfemoral endovascular treatment of proximal common carotid artery lesions: a single-center experience on 153 lesions

PURPOSE: To assess primary success and safety of percutaneous transluminal angioplasty (PTA) and/or stenting of ostial/proximal common carotid artery lesions (pCCA) and to compare its 30-day stroke/mortality level with the literature data for surgical options. METHODS: A total of 147 patients (153 stenoses, 6 recurrent) (71 female; 121 left) with significant diameter stenosis (>70% in symptomatic, n = 46; >85% in asymptomatic, n = 101 patients) of pCCA treated between 1994 and 2006 were retrospectively reviewed. With the exception of one, all procedures were performed using a transfemoral approach. A stent was implanted in 108 (70.5%) of cases. Stents were not available in the early years of our experience, but gradually became a routine practice. Embolic protection devices were used in 16 cases. Follow-up included neurological examination, carotid duplex scan, and office/telephone interview. RESULTS: Primary technical success was 98.7% (151/153 stenoses). There were no deaths. Periprocedural (<48 hours) neurological complications included 3/153 (2.0%) ipsilateral major strokes and 4/153 (2.6%) TIAs (including one contralateral TIA). There were 8/153 (5.2%) access site hematomas, 1/153 (0.7%) bradycardia, and 1/153 (0.7%) acute left ventricular failure with respiratory distress. Follow-up was achieved in 115/147 patients (78.2%) undergoing 120 procedures for a mean of 24.7 months and revealed one additional contralateral TIA and one additional minor stroke in an asymptomatic patient. In patients with follow-up, the 30-day procedural death/all-stroke rate was 3/120 (2.5%) The cumulative primary patency rate in the 115 patients with follow-up was 97.9% +/- 2.1% at 1 year, 82.0% +/- 7.1% at 4-years, and 73.5% +/- 12.7% at 7 years. The cumulative secondary patency rate was 100% at 1 year, 88.0% +/- 7.0% at 4 years, and 88.0% +/- 11% at 7 years. Log-rank test showed no statistical difference (P = .82) in primary cumulative patency between PTA alone (n = 34) or PTA/stent (n = 86). CONCLUSION: Transfemoral PTA/stenting appears to be appropriate treatment option for ostial/proximal common carotid artery significant stenoses. This study should also draw attention to the lack of data on natural history or effect of best medical treatment alone for these lesions, making evidence-based decision currently impossible for treatment of symptomatic or asymptomatic ostial and proximal common carotid artery significant stenoses

A Pilot Clinical Study of Hyperacute Serum Treatment in Osteoarthritic Knee Joint: Cytokine Changes and Clinical Effects

The serum fraction of platelet-rich fibrin (hyperacute serum) has been shown to improve cartilage cell proliferation in in vitro osteoarthritic knee joint models. We hypothesize that hyperacute serum may be a potential regenerative therapeutic for osteoarthritic knees. In this study, the cytokine milieu at the synovial fluid of osteoarthritic knee joints exposed to hyperacute serum intraarticular injections was investigated. Patients with knee osteoarthritis received three injections of autologous hyperacute serum; synovial fluid was harvested before each injection and clinical monitoring was followed-up for 6 months. Forty osteoarthritic-related cytokines, growth factors and structural proteins from synovial fluid were quantified and analysed by Multivariate Factor Analysis. Hyperacute serum provided symptomatic relief regarding pain and joint stability for OA patients. Both patients “with” and “without effusion knees” had improved VAS, KOOS and Lysholm-Tegner scores 6 months after of hyperacute serum treatment. Synovial fluid analysis revealed two main clusters of proteins reacting together as a group, showing strong and significant correlations with their fluctuation patterns after hyperacute serum treatment. In conclusion, hyperacute serum has a positive effect in alleviating symptoms of osteoarthritic knees. Moreover, identified protein clusters may allow the prediction of protein expression, reducing the number of investigated proteins in future studies
