Objective

Roughly 10% – 20% of pancreatic cancer patients are candidates for curative intent surgical treatment. In the 2000s, many studies showed similar survival rates comparing pancreatic surgery with or without vein resection and reconstruction. The aim was to identify the best method of venous reconstruction.

Methods

This was a retrospective cohort study. A total of 1 375 patients undergoing pancreatectomy between 2005 and 2018 were identified. Patients undergoing a combined pancreatic resection and venous reconstruction were included retrospectively. When tumour infiltration to the portal/superior mesenteric vein was detected, excision and reconstruction with tangential suturing/patch, end to end anastomosis, or a spiral graft from the great saphenous vein was performed. Next, 90 day and long term survival and outcomes across reconstruction techniques were analysed.

Results

Overall, 198 patients had venous involvement visible in pre-operative scans or detected during surgery... Read more

Coronary artery bypass grafting (CABG) is one of the foundations of treatment for coronary artery disease. While it has improved substantially since its inception more than 50 years ago, including a rising use of multiple arterial grafting, intraoperative quality assessment is yet to be disseminated as an integral part of the procedure.

Background: Diffuse intimal hyperplasia and graft irregularity adversely affect the long-term patency of saphenous vein grafts (SVGs) and clinical outcomes of patients undergoing coronary artery bypass grafting (CABG). The VEST trial evaluated the efficacy of external graft support in limiting the development of intimal hyperplasia (IH) at 1 year postsurgery. In the present secondary analysis, we explored the associations between graft disease and IH and clinical events. We also examined risk factors for early graft occlusion.

Methods: VEST is a within-patient randomized, multicenter trial that enrolled 224 patients with multivessel coronary disease undergoing CABG surgery, of whom 203 were evaluated by 1 year postsurgery. Intimal hyperplasia, lumen uniformity, graft stenosis, and graft perfusion were measured by intravascular ultrasound and angiography. Major cardiac and cerebrovascular events (MACCE; including death, myocardial infarction, stroke, and revascularization) were recorded over a median follow-up of 3 years.

Objectives: The aim of this study was to evaluate the impact of transit-time flow measurement (TTFM) on early postoperative outcomesin total arterial coronary revascularization.

Methods: A single-centre retrospective analysis was conducted on 910 patients undergoing isolated total arterial coronary artery bypassgrafting with internal thoracic arteries (ITAs) at our institution, between January 2017 and February 2020. Complete arterial revascularization with bilateral ITAs with a Y-configuration, or single ITA, was planned for all patients. According to the surgeon preference, TTFM was assessed in 430 patients (TTFM group). They were compared with 480 patients without TTFM assessment (no TTFM group). Primary endpoint was the occurrence of in-hospital major cardiac adverse events (MACE). A propensity score analysis with an inverse probabilityweighting approach was performed to control for selection bias.RESULTS: TTFM was associated with longer cardiopulmonary bypass times (76.0 [62.0; 91.2] vs 79.0 [65.0; 94.0] min, P = 0.042). Six (1.4%)patients in the TTFM group versus no patient in the no TTFM group underwent intraoperative graft revision because of unsatisfying flowvalues (P = 0.011). MACE were significantly lower in the TTFM group (14, 3.3%) than in the no TTFM group (33, 6.9%, P = 0.014). At crude regression, TTFM was protective against MACE occurrence (odds ratios 0.46, 95% confidence interval 0.23–0.85, P = 0.016). Inverse probability weighting adjustment did not significantly displace P-values and odds ratios for MACE occurrence in the TTFM group 0.44, 95% confidence interval 0.28–0.69, P < 0.001.

Objective:

This study aimed at assessing outcomes after carotid endarterectomy (CEA) in dependence of center policy with respect to imaging intraoperative completion study (ICSⁱ) usage.

Summary Background Data:

Although randomized controlled studies are missing, a beneficial effect was shown for ICSⁱ techniques (i.e., angiography and intraoperative duplex ultrasound) after CEA.

Methods:

This secondary data analysis is based on the... Read more...
