Modern Open Surgery for Coral Reef Aorta with Visceral Artery Involvement.
Eur J Vasc Endovasc Surg
December 2024
Department of Vascular Surgery, University Hospital of Rangueil, Toulouse, France.
Objective: Coral reef atherosclerosis of the visceral aorta (CRA) is associated with renovascular hypertension (RVH), chronic mesenteric ischaemia (CMI), and malperfusion of the lower limbs. The outcomes of open surgery for this rare disease are described in this paper.
Methods: This retrospective study included all patients who underwent open surgical repair of CRA at a single high volume referral centre between January 2009 and June 2023.
Pre-operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno-arterial extracorporeal membrane oxygenation or cardiac surgery.

Children requiring veno-arterial extracorporeal membrane oxygenation (VA ECMO) or cardiac surgery often undergo cervical cannulation or carotid artery clamping, which can interrupt cerebral circulation. Inadequate collateral flow through the circle of Willis (CoW) may lead to cerebral ischaemia within the vascular territory and/or watershed regions. Pre-cannulation survey of the CoW using transcranial Doppler (TCD) ultrasound may be performed to predict and plan neuroprotection.

Front Med (Lausanne)
September 2024
Department of Neurology, University Medicine Greifswald, Greifswald, Germany.
Article Synopsis
- This study looks at how doctors can figure out who might have memory problems after spine surgery in older patients, focusing on those 60 and up.
- They're using special tests before surgery, like brain scans and blood flow tests, to see if a certain measurement (the pulsatility index) can predict if someone will have issues like confusion after surgery.
- The results showed that about 1 in 5 patients had post-operative delirium, and older patients were more likely to experience it, with specific test scores helping to predict these problems.
Outcomes of robot-assisted laparoscopic pyeloplasty among pediatric patients with complex renal anatomy: A retrospective comparative study.

Article Synopsis
- Robot-assisted laparoscopic pyeloplasty (RALP) is an effective treatment for pediatric ureteropelvic junction obstruction (UPJO), with success rates over 95%, but can be challenging in cases with complex renal anatomy.
- This study evaluated the outcomes of RALP in children with complex renal anatomy (e.g., horseshoe kidney, ectopic kidney) compared to those with simple anatomy by analyzing data from 2012 to 2022.
- The results showed no significant differences in age, procedure time, length of hospital stay, or overall success rates between the two groups, though the causes of obstruction varied significantly between patients with complex vs. simple anatomy.
Intraluminal crossing of infrainguinal SFA chronic total occlusions may offer patency superiority compared to subintimal crossing.
Vascular
August 2024
Department of Surgery,Division of Vascular Surgery, University of Missouri, School of Medicine, Columbia, MO, USA.
Objectives: Patency for chronic total occlusions (CTO) of the superficial femoral artery (SFA) after endovascular interventions traditionally demonstrate a low 1-year patency ranging from 40%-60%. The optical coherence tomography (OCT) catheter (Avinger Inc., Redwood City, CA) uses light-based technology imaging to cross Trans-Atlantic Inter-Society Consensus D (TASC D) lesions intraluminally with direct intra-arterial visualization.
