Genicular Artery Embolization for Recurrent Hemarthrosis of the Knee Following Total Knee Arthroplasty: A Single Centre Experience.

Purpose: To retrospectively review the safety and efficacy of genicular artery embolization procedures performed at our institution in patients presenting with recurrent knee hemarthrosis following total knee arthroplasty (TKA).

Materials And Methods: A total of 13 consecutive patients (average age: 68; range 51-84, 62% female) were identified who underwent 14 genicular artery embolization procedures after presenting with recurrent hemarthrosis after TKA. Patient charts were retrospectively reviewed for demographic information, pre-embolization investigations, and details of embolization procedure including complications, technical success, and clinical success.

Low Contrast Dose Catheter-Directed CT Angiography (CCTA).

Purpose: Catheter-directed computed tomography angiography (CCTA) has been shown to reduce the contrast volumes required in conventional CTA, thus minimizing the risk of contrast-induced nephropathy (CIN).

Materials And Methods: A retrospective analysis was performed on cases where CCTA was used to assess access vessels prior to transfemoral aortic valve implantation (TAVI, n = 53), abdominal aortic aneurysm assessment for endovascular aneurysm repair (EVAR, n = 11), and peripheral vascular disease (PVD, n = 24).

Results: We show that CCTA can image vasculature with adequate diagnostic detail to allow assessment of lower extremity disease, anatomic suitability for EVAR, as well as potential contraindications to TAVI.
