St. Peter's Hospital (President Yoon, Kangjun), a general hospital focused on spine, joint and cerebro-cardiovascular care, announced on the 22nd that Professor SUH, Dae Chul of the Department of Neurointervention had received a Best Oral Presentation Award and a Best Publication Award at domestic and international academic conferences respectively, for research addressing the importance of selecting a WEB device matched to volume in WEB embolization of cerebral aneurysms.
The academic conference attended by Professor SUH, Dae Chul of Interventional Neuroradiology at St. Peter's Hospital was the joint regular conference of the East Asian Conference of Neurointervention (EACoN) and the Korean Society of Interventional Neuroradiology (KSIN), held together on the 13th at COEX Magok in Seoul. EACoN is an international neurointervention academic event at which specialists in interventional neuroradiology from Korea, China and Japan gather to share clinical research findings and treatment strategies, while the KSIN conference is likewise the leading annual academic event in the field of neurointervention in Korea.
Professor SUH, Dae Chul received the Best Publication Award at the KSIN conference for his paper 'Clinical analysis and initial concept for deriving WEB size according to cerebral aneurysm morphology', contributed to Neurointervention, the journal of the Korean Society of Interventional Neuroradiology. He then also received a Best Oral Presentation Award at the EACoN conference for his presentation 'WEB embolization strategy for boot-shaped cerebral aneurysms'.
Cerebral aneurysm embolization is an 'endovascular procedure' that lowers the risk of rupture by inserting a device through the blood vessels to block blood flow inside the aneurysm. Recently, embolization using the mesh-shaped flow disruptor WEB (Woven EndoBridge) has been gaining ground in particular. The technique is regarded as a state-of-the-art treatment that overcomes the limitations of conventional coiling and blocks the aneurysm more effectively.
Precise selection of WEB size is the single most important step determining the outcome of WEB embolization. Until now, however, the field has pointed to a clinical limitation: the lack of criteria for systematically judging the suitability of a WEB device for each aneurysm morphology.
In aneurysms of varied shape, such as asymmetric ones, suitability also needs to be considered from the standpoint of volume (three-dimensional space). At present, WEB size is generally selected on the basis of length measurements such as the diameter and width of the cerebral aneurysm, but in non-spherical, asymmetric cerebral aneurysms it is difficult to gauge the appropriate WEB size for the actual spatial structure.
Professor SUH, Dae Chul's research team focused on this point and analyzed 60 consecutive clinical cases of cerebral aneurysm actually treated with WEB embolization, assessing suitability by comparing aneurysm morphology with WEB volume.
For this study, Professor Suh's research team newly introduced the concept of 'WEB device suitability (WEB index)', which quantifies how closely the WEB engages with the aneurysm structure - that is, how well the WEB volume fits within the space of the aneurysm. Using this, the team quantitatively compared and analyzed the spatial suitability of the WEB device according to the morphological type of cerebral aneurysm.
When cerebral aneurysms were first analyzed by type, patients with asymmetric aneurysms accounted for 35% of the total, a not insignificant proportion. The team also confirmed that the shapes divide into five varied forms: pillar, submarine, spherical, boot, and mitten.
A clear difference emerged between symmetric and asymmetric aneurysms in particular in how the WEB device engaged with the three-dimensional structure of the aneurysm. In most cases a WEB of a length matching the measurement criteria was deployed, but in asymmetric aneurysms there were more cases in which the WEB did not engage precisely within the aneurysm space. These procedural outcomes were found to be significantly associated with the need for additional stent-assisted procedures, with residual sac and with recurrence.
From these findings the research team concluded that the outcome of WEB embolization is related to the choice of WEB according to the type of aneurysm structure. The importance of WEB size was greater still in asymmetric aneurysms. In the EACoN presentation, the team drew particular interest by setting out in concrete terms a methodology for WEB embolization of boot-shaped aneurysms, in which the engagement problem caused by spatial asymmetry is greatest.
The findings are expected to serve as an important reference for advancing cerebral aneurysm treatment strategies. As clinical use of WEB embolization continues to grow worldwide, discussion of WEB use that takes aneurysm morphology into account is expected to become considerably more concrete.
Professor SUH, Dae Chul of the Department of Neurointervention at St. Peter's Hospital is Korea's foremost authority in cerebral aneurysm treatment, and has independently developed a technique that improves both safety and treatment outcomes in the highly demanding field of anterior choroidal artery aneurysm embolization. He also shares his clinical and research results through numerous academic papers and presentations at international conferences, leading the academic and clinical advancement of cerebral aneurysm treatment.
Professor SUH, Dae Chul said, "It is all the more meaningful that research analyzing the relationship between aneurysm morphology and WEB volume, aimed at advancing WEB embolization, has been formally recognized," adding, "I will continue to press ahead with research and clinical work to improve the safety and precision of treatment for cerebral aneurysms and other highly demanding conditions."
