In our experience, eight of ten aortocoronary grafts in five patients remained patent in the face of mediastinal infection. Combining reports of seventeen other grafts from the literature, we conclude that patency can be anticipated in approximately 70 per cent of such grafts and that mediastinal infection does not necessarily adversely affect aortocoronary saphenous vein bypass graft patency. We recommend aggressive therapy of mediastinal infection in this setting due to the high survival rate which can be anticipated with modern methods of therapy, as well as the high probability of graft patency.

Background And Objectives: The key points of a monographic vascular access (VA) consultation are an adequate preoperative assessment, as well as a correct management and optimization of waiting lists. Our main objective of present study was to evaluate the degree of exploratory-dependent concordance in outpatient clinics regarding implanted VA, between nephrology and vascular surgery.
Materials And Methods: We analyzed VA created or surgically repaired between 2021 and 2022.

Background: Liver cirrhosis accounts for more than 90 % of portal hypertension cases, and the other cases are due to noncirrhotic portal hypertension (NCPH). Variceal bleeding is the most life-threatening complication of portal hypertension and its primary treatment is medical according to the Baveno VII guidelines. This review discusses the evidence on surgical portal decompression for adult patients with NCPH secondary to chronic extrahepatic portal vein obstruction (EHPVO).

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.
Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.
Remifentanil-Propofol-Ketamine- Based Total Intravenous Anesthesia with Spontaneous Breathing for Adult Rigid Bronchoscopy.

Rigid bronchoscopy (RB) is the gold standard for managing central airway obstruction (CAO), a life-threatening condition caused by both malignant and benign etiologies. Anesthetic management is challenging as it requires balancing deep sedation with maintaining spontaneous breathing to avoid airway collapse. There is no consensus on the optimal anesthetic approach, with options including general anesthesia with neuromuscular blockers or spontaneous assisted ventilation (SAV).
