: Partially thrombosed aneurysms represent a subset primarily found within large and giant aneurysms. The presence of an intraluminal thrombus can cause an aneurysm to present in different shapes upon angiographic examination. We present a series of five cases of "donut-shaped" aneurysms observed over the past decade at the Clinic for Neurosurgery in the University Clinical Centre of Serbia. : The management of "donut-shaped" aneurysms was accomplished through endovascular interventions, employing techniques such as the deployment of flow-diverting stents or a combination of stent placement and coil embolization. : Four out of five patients underwent endovascular treatment, yielding positive outcomes with complete thrombosis of the aneurysms during follow-up. The fifth patient was successfully diagnosed; however, due to their deteriorating condition, treatment was not feasible. : Given the potential life-threatening complications associated with this entity, accurate diagnosis and appropriate management are crucial. In our cohort, endovascular interventions demonstrated efficacy in the majority of cases, underscoring the significance of this approach in treating "donut-shaped" aneurysms. Nevertheless, considering the rarity of this condition, further research is justified to refine diagnostic and therapeutic strategies for these complex intracranial vascular anomalies.
部分血栓形成的动脉瘤是主要见于大型和巨型动脉瘤的亚组。腔内血栓的存在可导致动脉瘤在血管造影检查时呈现不同的形状。我们在过去十年中在塞尔维亚大学临床中心神经外科诊所观察到了五例“甜甜圈形”动脉瘤的系列病例。
通过血管内介入治疗来处理“甜甜圈形”动脉瘤，采用了血流导向支架的部署或支架放置和线圈栓塞相结合等技术。
五例患者中有四例接受了血管内治疗，在随访期间，动脉瘤完全血栓形成，结果良好。第五例患者得到了明确诊断；然而，由于他们的病情恶化，治疗不可行。
鉴于这种实体与潜在的危及生命的并发症相关，准确的诊断和适当的管理至关重要。在我们的病例组中，血管内介入治疗在大多数情况下显示出疗效，强调了这种方法在治疗“甜甜圈形”动脉瘤中的重要性。然而，考虑到这种情况的罕见性，有理由进一步研究以完善这些复杂的颅内血管异常的诊断和治疗策略。
