Article Abstract
Detachable coils grant controlled deployment, retrieval, and repositioning until desired placement is achieved for complex visceral artery aneurysms (VAAs), but a detailed investigation is needed for its clinical application. Between June 2018 and September 2020, 28 patients with 31 complex VAAs successfully treated with detachable coils in two hospitals were retrospectively analyzed. The technical success rate reached 100%. Then, 96.8% (30/31) of the afferent arteries and 94.9% (75/79) of the efferent branches were patent without occlusion after the procedure. At the last follow-up, 77.4% and 12.9% of aneurysms were graded as class I and class IIIa, respectively, according to the Modified Raymond-Roy Occlusion Classification. Compared to immediately after the procedure, the number of aneurysms decreased in classes II, IIIa, and IIIb, whereas the number of class I aneurysms significantly increased from 18 to 24 at the last follow-up. Bleeding was not identified in any patients, but three patients (two with abdominal pain and one asymptomatic) developed ischemic complications of either splenic or renal infarction. Overall, transarterial embolization with detachable coils was safe and effective for treating complex VAAs, and the procedure should be performed with caution to avoid ischemic complications.

Retrograde transvenous coil embolization in spinal epidural arteriovenous fistula with radiculo-perimedullary reflux.

Spinal epidural arteriovenous fistulas (SEAVFs) with intradural reflux are rare but important vascular lesions that may cause progressive myelopathy due to spinal cord venous hypertension. Although traditionally managed by means of arterial embolization or surgical disconnection, these approaches can pose risks, particularly when critical vascular structures, such as the artery of Adamkiewicz, originate in close proximity to the fistulous site. We report the case of a patient in their 60s who presented with progressive paraparesis over approximately 1 year, ultimately attributed to an SEAVF located adjacent to the right L1-L2 neural foramen, with radiculo-perimedullary reflux.

Anomalous systemic arterial supply to the left lower lobe (ASALLL) is a rare congenital vascular malformation. It predominantly occurs in young and middle-aged adults, often presenting with recurrent hemoptysis of unknown etiology. The condition has a high clinical misdiagnosis rate, and its optimal treatment remains controversial.

Splenic arteriovenous shunts (SAVSs) are rare vascular malformations that can lead to portal hypertension and subsequent formation of portosystemic venous shunts (PVSs), potentially causing hepatic encephalopathy even without liver cirrhosis. We report a case of a 75-year-old woman with Parkinson's disease who presented with worsening cognitive function, flapping tremors, and visual hallucinations. Laboratory tests revealed hyperammonemia (180 µg/dL), and brain magnetic resonance imaging showed high signal intensity in bilateral basal ganglia on T1-weighted image.

Background: Coil embolization for cerebral aneurysms is an important technique and is not likely to be replaced in the foreseeable future. Recently, the Target Tetra detachable coil (TTDC) has become available, thereby raising expectations for a safer embolization in small aneurysms. Based on our experience, we report the behavioral characteristics and effective utilization of TTDCs.

Importance: Vein of Galen malformation (VOGM) is the most common congenital cerebrovascular anomaly. Fetuses with VOGM and wide mediolateral falcine sinus diameters are at high risk for mortality, brain injury, and neurodevelopmental delay. In utero embolization may improve survival and outcomes.
