Anatomy of Risk: Decoding the Predictors of Vascular Access Complications in Transcatheter Aortic Valve Replacement.
Catheter Cardiovasc Interv
December 2024
Department of Surgery, University of North Dakota School of Medicine and Health Sciences, Grand Forks, North Dakota, United States.
Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.
Impact of vascular supply variability on the prognosis of meningioma patients: a retrospective study based on territory arterial spin labeling.
Quant Imaging Med Surg
December 2024
Department of Radiology, Huashan Hospital, Fudan University, Shanghai, China.
Background: Territorial arterial spin labelling (t-ASL) could be an alternative method to digital subtraction angiography (DSA) when evaluating feeding arteries by previous reports, however, blood supply variations on meningioma prognosis remains unclear. In this study, the prognosis of meningiomas mainly supplied by the internal carotid artery (ICA) and external carotid artery (ECA) was compared, and relevant clinical factors were investigated.
Methods: t-ASL technique was employed to categorized pathologically-confirmed meningioma patients into the ICA, ECA, ICA co-supplied, and non-ICA co-supplied group.
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 (PAD). 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.
Assessment of aortic arch involvement in ascending thoracic aortic aneurysm by three-dimensional growth mapping using CT-angiography.
Eur Radiol
November 2024
Department of Radiology, University of Michigan, Ann Arbor, MI, USA.
Article Synopsis
- The study aimed to investigate pre-surgical growth of the aortic arch using vascular deformation mapping (VDM) and how the proximal arch diameter correlates with involvement of a primary ascending aortic aneurysm.
- The research included 123 patients who had multiple pre-operative CT scans and found that VDM indicated higher growth rates in patients with dilated arches, yet standard diameter measurements often failed to identify significant growth in non-dilated arches.
- The findings suggest that VDM provides a more accurate assessment of arch involvement than just measuring diameter, which could enhance individualized surgical approaches for patients with ascending thoracic aortic aneurysms.
Meandering Mesenteric Bypass: A Case Report on a Novel Surgical Technique for Managing Mesenteric Ischaemia When Endovascular Fails.
EJVES Vasc Forum
October 2024
Auckland Regional Vascular Service, Auckland City Hospital, Auckland, New Zealand.
Introduction: Endovascular revascularisation (ER) is often used as first line treatment for chronic mesenteric ischaemia, with high technical success and a lower rate of peri-operative adverse events than open surgical repair. Distal embolisation following ER is a potentially life threatening complication with a high mortality rate.
