Objective: To present endovascular techniques in the treatment of juxtarenal aortic aneurysms (JAAAs) in relation to surgical repair; this is the "gold standard."
Methods: Between January 2008 and December 2010, 90 consecutive patients were diagnosed with primary degenerative JAAAs (≥5.0 cm) and assigned prospectively to different operative strategies on the basis of morphologic and clinical characteristics. In particular, 59 patients were treated by endovascular means such as fenestrated endovascular abdominal aortic repair (f-EVAR, n = 29) or chimney endovascular abdominal aortic repair (ch-EVAR, n = 30) endografting, and 31 patients underwent open repair (OR, n = 31).
Results: Early procedure-related and all-cause (30-day) procedure-related mortality was 0% for the endovascular group and 6.4% (n = 2/31) for the OR group, due to systemic inflammatory response syndrome with consecutive multi-organ failure (P = .023). Persistent postoperative hemodialysis occurred only after OR (2/31; 6.4%). The overall estimated pre- and postoperative median estimated glomerular filtration rate and creatinine values were similar in the three subgroups. There was one left renal artery occlusion for each endovascular subgroup, which presented as flank pain and was treated by iliaco-renal bypass in both cases. Transfusion requirements and length of hospital stay were significantly less in the endovascular group (P = .014 and P = .004, respectively).
Conclusions: Endovascular treatment of JAAA is a safe alternative for the short-term management of JAAA.

Pre-distance assessment from radial artery to lower extremity arterial lesion.
Int J Cardiovasc Imaging

Department of Cardiovascular Medicine, Kyoto Prefectural University of Medicine, Kyoto, Japan.
Endovascular treatment (EVT) for patients with lower extremity artery disease is widely used as a less invasive alternative to surgical bypass. Recently, transradial artery intervention has gained popularity owing to its minimally invasive nature. The distance from the radial artery to the target vessel is critical for success; however, effective pre-assessment methods have not yet been established.

Introduction: Older patients may be denied endovascular revascularization of the superficial femoral artery (SFA) for peripheral artery disease (PAD) due to concerns of worse limb outcomes than younger patients.
Methods: We assessed adverse outcomes in patients after an index revascularization stratified by age (age < 65, 65-75 years, and > 75 years) from two centers between 2003 and 2011 and followed a median 9 (25 %-75 %: 7, 11) years. Outcomes included major adverse limb events (MALE) or minor repeat revascularization, death, and major adverse cardiac and cerebrovascular events (MACCE).
Efficacy and safety of the PHIL embolic agent in the treatment of intracranial dural arteriovenous fistulas: results of the PHIL-dAVF study.
J Neurointerv Surg
January 2025
Diagnostic and Therapeutic Neuroradiology, Hôpital Purpan, Toulouse, France.
Background And Purpose: Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent is a non-adhesive copolymer with specific features and endovascular behavior. This study assessed its safety and efficacy in a prospective real-life cohort.

Radiology, The Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.
Background: We aim to share our experience of transradial access (TRA) for cerebral angiography and intervention in five patients ranging from 6 days to 7 months of age.
Methods: In this institutional review board-approved, retrospective case series, we reviewed all patients who underwent TRA for cerebral angiography with and without intervention. We describe three techniques for radial artery cannulation, namely: (1) bareback; (2) with a micropuncture sheath; and (3) with an intravenous catheter.
First pass effect in patients with large core infarcts undergoing mechanical thrombectomy: subgroup analysis of the prospective international ASSIST registry.
J Neurointerv Surg
January 2025
Semmes-Murphey Neurologic and Spine Institute, Memphis, Tennessee, USA.
Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.
Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.
