The absence or dysplasia of the iliac artery(IA) is an exceedingly rare condition, with limited cases documented in the literature. In this report, we present a case of hypoplasia of the right external iliac artery (EIA) in a 69-year-old male patient. The patient presented with right lower abdominal pain attributed to an aneurysm of the right internal iliac artery (IIA), yet notably, there was no evidence of lower limb ischemia at the time of consultation.

Purpose: This study aimed to identify major lesion characteristics of chronic total occlusions (CTOs) that predict failed percutaneous coronary intervention (PCI) using pre-procedure coronary computed tomography angiography (CCTA) in combination with conventional coronary angiography (CCA).
Methods: Consecutive patients with at least one CTO of the native coronary arteries received CCTA and CCA-guided PCI, with computed tomography performed before or during PCI.
Results: A total of 76 patients with CTO were included in this study.
Association of Narrow Anterior Communicating Artery or Contralateral A1 Segment with Poor Outcomes After Mechanical Thrombectomy.

Contralateral A1 and AComA aplasia/hypoplasia are critically important in distal ICA T occlusion as the protective collateral blood supply from the circle of Willis via the anterior communicating artery is compromised. Although the terms aplasia/hypoplasia are used broadly in the literature, the need for concrete measurements and data on their clinical significance is apparent. Features of the individual anatomy of the circle of Willis may determine patient outcomes.

Division of Neurosurgery, University of Montreal Hospital Center, Montreal, Quebec, Canada.
Background: The mechanisms underlying the initiation and progression of bifurcation versus lateral wall aneurysms are not well understood. Computational fluid dynamics (CFD) can improve the understanding of these mechanisms and can consequently help identify patients at higher risk for developing aneurysms and monitor them more closely.
Observations: A 36-year-old man presented with a ruptured anterior communicating artery aneurysm, which was successfully treated with microsurgical clipping.

Background: The mortality rate of splenic artery aneurysm rupture is very high, and patients with aneurysms larger than 30 mm are recommended for treatment, regardless of the presence or absence of symptoms. We herein report a case of splenic artery aneurysm with an abnormal bifurcation that was treated with laparoscopic ligation of the splenic artery.
Case Presentation: A 51 year-old Japanese male was referred to our hospital because a splenic artery aneurysm was noted on abdominal echocardiography during a medical examination.
