Zusammenfassung Hintergrund Der direkt laterale Zugangsweg hat in den letzten Jahren zunehmend an Popularität gewonnen. Er könnte neben der Diskektomie aber auch für Teil-Korporektomien an der thorakolumbalen Wirbelsäule genutzt werden. Wir präsentieren hiermit nun unsere Erfahrung der letzten 5 Jahre (2012 – 2017). Methoden Es wurde retrospektiv unsere Datenbank ausgewertet, die ab 2012 kurz nach Markteinführung alle Patienten erfasste. Es wurden prä- und postoperative CT- und Röntgenaufnahmen in unserem PACS-System gespeichert. Die Patienten wurden 3 Monate nach der Operation erneut in unserer Ambulanz gesehen und das klinische Outcome bestimmt. Eine Vergleichsgruppe konnte für die Schmerzanalyse bei Patienten mit Metastasen an der Wirbelsäule gebildet werden, da nicht alle Patienten über denselben Zugang in dem Zeitraum operiert wurden. Ergebnisse Im Zeitraum zwischen März 2012 und März 2017 wurden 45 Patienten in den Höhen Th7 bis L4 operiert. Bei 30 Patienten waren spinale Metastasen die Indikation und bei 15 Patienten lag eine Berstungsfraktur zugrunde. Im gleichen Zeitraum wurde bei 8 Patienten eine Kostotransversektomie als operativer Zugang zur Resektion von osteolytischen Metastasen an der Wirbelsäule durchgeführt. Bei 88 % der Patienten konnte eine 90 %-Deckplattenabdeckung erreicht werden. In der Vergleichsanalyse zeigte sich, dass die Patienten, die sich einem minimalinvasiven lateralen Zugang unterzogen, einen signifikant geringeren kombinierten Blutverlust und weniger unmittelbar postoperative Schmerzen hatten. Neurologische Komplikationen erlitten 6 Patienten (13 %). Implantatassoziierte Komplikationen wurden in 7 Fällen (15 %) beobachtet, davon 5 revisionspflichtig. Schlussfolgerung Unsere Serie untersucht anhand von 45 Patienten die mini-open direkt laterale Teil-Korporektomie. Diese Technik ist ein wertvolles minimalinvasives Zugangsverfahren für Tumoren und Frakturen der Wirbelsäule insbesondere bei Wirbelkörperdestruktionen mit der Möglichkeit einer exzellenten Deckplattenabdeckung durch das lateral eingebrachte Implantat. Weitere Nachuntersuchungen und Erfahrungen sind notwendig, um das Indikationsspektrum sowie die Langzeitergebnisse zu untersuchen.

Coronary artery stenting has evolved substantially since the first use of coronary stenting as an adjunct to balloon angioplasty in the early 1990s. The performance (and particularly the deliverability) of coronary stents has improved such that coronary stenting is now the primary mode of revascularisation for percutaneous coronary interventions (PCIs) in more than 95% of cases. The new Svelte™ stent-on-a-wire (SOAW) delivery system represents one of the first substantive innovations in stent delivery systems (SDS) in more than a decade. This SDS uses a shapeable ‘fixed wire’ as an integral part of the SDS. This allows a significant reduction in SDS profile (~0.029 inches) compared with conventional monorail or over-the-wire SDS. This SOAW SDS is intended to facilitate direct stenting. It has the potential to provide substantial procedural cost savings by eliminating the need for a coronary guidewire and balloon pre-dilatation and/or post-dilatation, and by reducing contrast use and the time required to complete the procedure. The SOAW system is compatible with 5Fr guiding catheters, and may reduce the need for closure devices, facilitate stenting via the radial approach and (potentially) reduce bleeding risks. In conclusion, the Svelte SOAW SDS represents a new very-low-profile balloon-expandable SDS that should promote direct stenting in PCIs. The efficiency and small profile of this SDS may allow procedural cost savings, a reduction in procedure time and a reduced risk of bleeding complications. These theoretical advantages will need to be demonstrated in clinical trials.

ABSTRACT Introduction:  The introduction of low profile devices designed for Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) after trauma has the potential to change practice, outcomes and complication profiles related to this procedure. Methods: The AAST Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery (AORTA) registry was utilized to identify REBOA patients from 16 centers -comparing presentation, intervention and outcome variables for those REBOA via traditional 11-12 access platforms and trauma-specific devices requiring only 7 F access. Results:From Nov 2013-Dec 2017, 242 patients with completed data were identified, constituting 124 7F and 118 11-12F uses. Demographics of presentation were not different between the two groups, except that the 7F patients had a higher mean ISS (39.2 34.1, p = 0.028). 7F device use was associated with a lower cut-down requirement for access (22.6% vs. 37.3%, p = 0.049) and increased ultrasound guidance utilization (29.0% 23.7%, p = 0.049). 7F device afforded earlier aortic occlusion in the course of resuscitation (median 25.0 mins vs. 30 mins, p = 0.010), and had lower median PRBC (10.0 vs. 15.5 units, p = 0.006) and FFP requirements (7.5 vs. 14.0 units, p = 0.005). 7F patients were more likely to survive 24 hrs (58.1% vs. 42.4%, p = 0.015) and less likely to suffer in-hospital mortality (57.3% vs. 75.4%, p = 0.003). Finally, 7F device use was associated with a 4X lower rate of distal extremity embolism (20.0% vs. 5.6%, p = 0.014;OR 95% CI 4.25 [1.25-14.45]) compared to 11-12F counterparts. Conclusion: The introduction of trauma specific 7F REBOA devices appears to have influenced REBOA practices, with earlier utilization in severely injured hypotensive patients via less invasive means that are associated with lower transfusion requirements fewer thrombotic complications and improved survival. Additional study is required to determine optimal REBOA utilization.
