Purpose: To report our experience with 10 cases of bronchial artery embolization (BAE).
Materials And Methods: The study included 18 cases (11 men and 7 women between 21 and 81 years of age, average 52 years), whose massive hemoptyses could not be controlled with conservative and bronchoscopic methods and were sent to the digital subtraction angiography unit between August 2002 and May 2004. Of these 18 cases, BAE was performed in 10 (7 men and 3 women between 21 and 78 years of age, average 54.2 years). An aortogram with a 5F pigtail catheter and a selective bronchial angiogram with a 4F glide Cobra (C2) catheter was obtained in every case. The same C2 catheters that had been used for bronchial angiography were also used for BAE in 7 cases. Hydrophilic microcatheters were additionally needed for BAE in the other 3 cases. Particles > 250 microns (polyvinyl alcohol [PVA], Embosphere microspheres), mechanical coils, or a combination of both were used for BAE.
Results: The etiologies of 10 cases in which BAE was performed were tuberculosis (n=3), sarcoidosis (n=3), bronchiectasis (n=2), and malignancy (n=2). Arterial bronchial pathology was also seen in the non-selective angiographic studies of 4 of the 10 BAE cases. Hemoptysis was controlled in all BAE cases in the first session. Recurrences were observed in 2 cases that were embolized with only mechanical coils during the first month follow-up and hemoptysis was again controlled with microparticle embolization with Embosphere microspheres. All 10 cases were followed- up for 1-21 months (average, 8 months).
Conclusion: Non-selective angiographic examination alone, is not sufficient enough to detect the vascular pathology causing a massive hemoptysis. A selective study must be performed in every case. The cost of angiography can be lowered by using the same 4F glide C2 catheter for BAE. It may not be safe to use only mechanical coils in BAE cases. There is a need for studying additional cases to have more definitive conclusions.

Department of Ophthalmology, Institute of Vision Research, Severance Eye Hospital, Yonsei University College of Medicine, South Korea.
Purpose: To compare the clinical outcomes of Xen 45 gel stent implantation surgery (Ab externo, open conjunctiva) with those of trabeculectomy.
Method: We retrospectively reviewed electronic medical record of 57patients (62eyes) treated with Xen implantation surgery (ab externo, open conjunctiva approach) between April 1st, 2021 and July 31st, 2023 by the same surgeon. Preoperative clinical data including intraocular pressure, the number of glaucoma medications, visual acuity were collected from 1 day to 12 months postoperatively.
Characteristics and outcomes of portal vein thrombosis in patients with inflammatory bowel disease in Korea.
Korean J Intern Med

Department of Gastroenterology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.
Background/aims: Portal vein thrombosis (PVT) frequently occurs in patients with inflammatory bowel disease (IBD), particularly when influenced by factors such as abdominal infections, IBD flare-ups, or surgical procedures. The implications of PVT range from immediate issues such as intestinal ischemia to long-term concerns including portal hypertension and its complications. However, there is a notable gap in comprehensive studies on PVT in IBD, especially with the increasing incidence of IBD in Asia.

Background And Aims: While biologic therapy has revolutionized the treatment of Crohn's disease (CD), surgery remains unavoidable in cases involving ileal complications. We aimed to evaluate the efficacy of biologics on proximal ileal lesions using balloon-assisted enteroscopy (BAE).
Methods: This open-label multicenter prospective study was conducted at tertiary referral centers in Japan.
Clinical Course and Prognostic Factors in Non-Neovascular Age-Related Macular Degeneration with Subretinal Fluid.
Retina
December 2024
Department of Ophthalmology, Seoul National University College of Medicine, Seoul National University Hospital, Seoul, Korea.
Purpose: To investigate the clinical course and prognostic factors of age-related macular degeneration (AMD) without macular neovascularization (MNV) in patients presenting with pigment epithelial detachment (PED) and the associated subretinal fluid (SRF).
Methods: Morphological characteristics of spectral-domain optical coherence tomography images were analyzed to determine anatomic outcomes. Factors associated with the progression to late AMD, defined as complete retinal pigment epithelium and outer retinal atrophy (cRORA) or MNV, were investigated.

Massive hemoptysis is a life-threatening condition. Bronchial artery embolization (BAE) is an effective technique for controlling bleeding in cases of severe hemoptysis, with infrequent complications. While rare, spinal cord infarction is a serious potential complication of BAE.
