Objective: To evaluate the effect of endovascular embolization of internal carotid-posterior communicating artery (IC-PC) aneurysm.
Methods: 145 patients with IC-PC aneurysms underwent endovascular embolization through the microcatheter under digital subtraction angiography (DSA). Of the 145 cases, 55 patients with 62 aneurysms were embolized by mechanical detachable spiral (MDS) and 90 patients with 106 aneurysms were embolized by Guglielmi detachable coil (GDC) or electrical detachable coil (EDC).
Results: 168 aneurysms in 145 patients, 96 of which with 100% embolization, 45 with 95% embolization, 15 with 90% embolization, and 12 with less than 90% embolization, were embolized successfully. During the surgery, aneurysm rupture occurred in 3 cases, cerebral vasospasm in 5, and cerebral infarction in 1 case. 118 cases were cured, 23 improved, and 3 died. 17 patients were followed-up by DSA, 3 aneurysms recurred and 2 were totally embolized with EDC for the second time.
Conclusion: Endovascular embolization is a safe and effective therapeutic method for IC-PC aneurysm.

A 2-day-old neonate was referred to the vascular surgery service owing to concerns of limb perfusion after entrapment of a microcatheter in the middle cerebral artery. The catheter was inserted via the umbilical artery to treat a vein of Galen arteriovenous malformation. This catheter inadvertently became entrapped owing to device failure, was cut at the insertion site, and left in situ for 3 months.

We document a case of a 75-year-old patient with a history of hypercholesterolemia and hypertension, who underwent endovascular aortic repair (EVAR) for an infrarenal abdominal aortic aneurysm (AAA) with common iliac artery ectasia. Despite an initially successful procedure, the patient experienced recurrent episodes of acute limb ischemia in his right leg. Subsequent imaging revealed thrombus formation distal to the stent graft, constituting a potential source of embolization, which warranted a reevaluation of the treatment strategy.

Background: Carotid body tumor (CBT) is a rare neoplasm that arises from the chemoreceptor cells located at the carotid bifurcation. Giant CBTs are extremely rare, with only 16 cases reported to date.
Case Summary: A 63-year-old male with an unremarkable medical history presented with a right-sided, giant, Shamblin III CBT.

Background: Variability in long-term endovascular treatment outcomes for intracranial aneurysms has prompted questions regarding the effects of these treatments on aneurysm hemodynamics. Endovascular techniques disrupt aneurysmal blood flow and shear, but their influence on intra-aneurysmal pressure remains unclear. A better understanding of aneurysm pressure effects may aid in predicting outcomes and guiding treatment decisions.

Intravenous thrombolysis (IVT) and endovascular therapy (EVT) are the cornerstones of acute ischemic stroke treatment. While IVT has been an integral part of acute therapy since the mid-1990s, EVT has evolved as one of the most effective treatments in medicine over the past decade. Traditionally, systemic thrombolysis has been performed with alteplase (rtPA).
