Abstract

Objectives

Although off-pump coronary artery bypass (OPCAB) has been reported to have better short-term results than on-pump coronary artery bypass (ONCAB) in terms of bleeding and stroke even in patients with cardiac dysfunction, details are unknown. The purpose of this study was to evaluate the outcomes of CABG (coronary artery bypass graft) in patients with low cardiac function based on our treatment policy.

Methods

Retrospectively, we reviewed patients with low ejection fraction (< 35%), who underwent isolated OPCAB or ONCAB between 2013 and 2020 in our institute.

Results

Isolated CABG was performed for 67 patients: 54 OPCABs and 13 ONCABs. In the ONCAB group, six were converted from OPCAB. Patients with AMI, heart failure, liver dysfunction, cardiogenic shock, and ventricular arrhythmia were more common in the ONCAB group. More patients required postoperative mechanical circulatory support in the ONCAB group. Intra-operative blood transfusion, ICU stay, intubation time, and hospital stay were significantly worse in the ONCAB group. Postoperative graft patency was 91.5%. Hospital mortality was 7.5%. Mid-term survival at 30-day, 1-year, and 5-year were 98.5%, 84.6%, and 75.8%, respectively.

Conclusion

In our institute, ONCAB was selected for the patients who could not complete treatment with OPCAB due to poor preoperative circulatory status. Our treatment policy for the patients with impaired cardiac function was acceptable.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

CME: 2 Punkte

Prof. Dr. med. Gregor Antoniadis Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

CME: 2 Punkte

Dr. med. Benjamin Meyknecht, PD Dr. med. Oliver Pieske Das Webinar S2e-Leitlinie „Distale Radiusfraktur“ beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
