A 49-year-old man was diagnosed with an interrupted aortic arch (IAA), a massive saccular thoracic collateral aneurysm, ischemic renal insufficiency, and multiple abdominal collateral aneurysms. A bypass from the left subclavian artery to the descending aorta and thoracic collateral aneurysmectomy proceeded simultaneously through a posterolateral thoracotomy. The pressure gradient between upper and lower extremities disappeared and renal function was normalized. Thoracic collateral aneurysmectomy and a simultaneous bypass from the left subclavian artery to the descending aorta with postoperative normalization of ischemic renal insufficiency are extremely rare in adult patients with IAA, and the remaining abdominal collateral aneurysms require careful monitoring.

Systemic-to-pulmonary collaterals (SPCs) are common in congenital heart disease (CHD). Particularly in single ventricle anatomy and Fontan circulation, SPC can both complicate the postoperative course and lead to clinical deterioration in the long term. The treatment of SPC is controversial.

Collateral vascular arteries from the descending aorta to the pulmonary arteries are uncommon after arterial switch operation. We describe a case of transposition of the great arteries (TGA) with significant aortopulmonary collateral vessels causing management difficulties after an arterial switch operation. Preoperatively, the presence of collaterals exacerbated aortic diastolic runoff and led to myocardial ischemia.

Open surgical treatment of idiopathic chylothorax via thoracic duct ligation and pericardiectomy requires a lengthy procedure with two thoracotomy incisions. The objectives of this report were to describe an approach for thoracic duct ligation and pericardiectomy via a single thoracotomy at the left fourth intercostal space and to describe the clinical outcome in two dogs with idiopathic chylothorax. Dogs were prospectively enrolled in a pilot study to evaluate the clinical efficacy of thoracic duct ligation at the left fourth intercostal space, combined with subphrenic pericardiectomy performed through the same incision.

Background: The feasibility of creating arteriovenous (AV) access in hemodialysis patients with superior vena cava occlusion (SVCO) is debated due to impaired blood return to the right atrium. However, collateral venous networks may offer an alternative solution, allowing for the creation of peripheral AV access. This study evaluates the outcomes of AV access construction in hemodialysis patients with SVCO.

Article Synopsis
- Selective antegrade cerebral perfusion (SACP) is a technique used to maintain brain blood flow during aortic arch surgeries that require temporary stopping of blood circulation, with two methods: bilateral (bSACP) and unilateral (uSACP), each having its risks.
- A new predictive method was developed and tested to determine cerebral perfusion pressures (CPP) during SACP, helping surgeons decide which SACP approach to use preoperatively, utilizing patient-specific imaging and simulations.
- The study involved five patients and demonstrated that the prediction method was accurate, with minimal errors in CPP predictions, highlighting the importance of collateral artery size for accurate modeling in surgical planning.
