A 45-year-old woman with repaired complex congenital heart disease, who underwent placement of Jarvik 2000, a ventricular assist device (VAD) for 4 years, experienced abdominal pain due to outflow graft compression caused by seroma formation between the outflow graft and ringed Gore-Tex graft. We exchanged the pump of Jarvik 2000 and punched several small holes in the new ringed Gore-Tex graft. Seroma formation between the two grafts should be considered as a cause of outflow graft obstruction in patients with the long-term support of VAD, and additional surgical interventions to the ringed Gore-Tex graft may prevent this complication.

Establishing reference curves for vital tissue perfusion using quantitative near-infrared fluorescence imaging with indocyanine green.
Langenbecks Arch Surg
January 2025
Department of Surgery, Leiden University Medical Center, Albinusdreef 2, 2333 ZA, Leiden, The Netherlands.
Purpose: Assessment of tissue perfusion using near-infrared fluorescence (NIR) with indocyanine green (ICG) is gaining popularity, however reliable and objective interpretation remains a challenge. Therefore, this study aimed to establish reference curves for vital tissue perfusion across target tissues using this imaging modality.
Methods: Data from five prospective study cohorts conducted in three Dutch academic medical centres between December 2018 and June 2023 was included.

Background: Takayasu arteritis is a large-vessel vasculitis, in addition to giant cell arteritis. Various post-operative complications associated with the cardiac macrovasculature have been reported. Detachment of the prosthetic valve, pseudoaneurysm formation, and dilatation of the aortic root are well-known post-operative complications associated with vasculitis syndromes, including Takayasu arteritis.

Background: The Resection and Partial Liver Transplantation with Delayed Total Hepatectomy (RAPID) procedure for unresectable colorectal liver metastases (uCRLM) has renewed interest by increasing, in selected cases, patients' long-term survival. Initially described using deceased donor graft, this technique evolved to living donors, tackling organ-shortage issues, allowing better scheduling, and reducing liver failure risk.
Methods: A 50-year-old patient presented 18 months earlier with a colic adenocarcinoma with synchronous uCRLM.
Simultaneous pancreas-kidney (SPK) transplantation is a recognized treatment for patients with insulin-dependent diabetes and advanced chronic kidney disease or end-stage renal disease (ESRD), offering significant survival benefits. However, it is associated with a higher risk of venous thrombosis, which can jeopardize the survival of the pancreaticoduodenal graft. This case report describes a patient with type 2 diabetes, hypertension, and ESRD who developed acute, occlusive deep vein thrombosis (DVT) involving the right common femoral, profunda femoral, and greater saphenous veins on postoperative day 1 (POD1) following a deceased donor SPK transplant, despite systemic prophylactic anticoagulation.

Department of Cardiovascular Surgery, Kanazawa University, Takaramachi 13-1, Kanazawa, 920-8641, Japan.
Background: Acute type A aortic dissection (A-AAD) with severe acute aortic regurgitation (AR) and coronary involvement is a potentially fatal condition that causes left ventricular volume overload and catastrophic acute myocardial infarction. We present the successful management of a patient using Impella 5.5 following cardiopulmonary arrest caused by A-AAD with severe acute AR and left main trunk (LMT) obstruction.
