Purpose: Endovascular treatment (EVT) has been shown to be effective and safe for isolated iliac artery aneurysms (IAAs). However, concerns remain regarding the lack of consideration to recent advances in perioperative care and surgical techniques, as well as a significant number of re-interventions with EVT. This study compares the outcomes of open surgical repair (OSR) and EVT using recent clinical data. Materials and Methods: This retrospective, single-center study included patients who underwent OSR or EVT for isolated degenerative IAAs between January 2007 and December 2018. Primary outcomes were procedure time, number of transfusions during admission, length of hospital stay, complications, and number of preserved internal iliac arteries. Secondary outcomes included all-cause and aneurysm-related mortality, and re-intervention rates. Results: Fifty-eight consecutive patients underwent treatment for isolated IAAs (25 underwent OSR and 33 underwent EVT), with a median follow-up of 75 months (range: 39-133 months). Baseline characteristics were similar between the groups, except for a lower mean age in the OSR group than in the EVT group (66.0±8.2 vs. 73.1±8.6, P=0.003). Both groups had a mild risk of comorbidity severity score.Early complications (within 30 days of the procedure) occurred more frequently in the OSR group, though not statistically significant (24.0% vs. 6.1%, P=0.07). Late complications, including sac expansion and thrombotic occlusion, were significantly more common in the EVT group (15.2% vs. 0%, P=0.04). Re-intervention rate was higher in the EVT group but not statistically significant (9.1% vs. 4.0%, P=0.44). No significant differences were observed in major adverse cardiovascular events and mortality between the groups (P=0.66 and P=0.27), and there were no aneurysm-related deaths. Conclusion For patients with mild risk factors, EVT does not offer a survival or re-intervention advantages over OSR in the treatment of isolated IAAs. However, EVT is associated with an increased risk of late complications. Although larger randomized studies are necessary, OSR may be considered the first-line treatment for isolated IAAs in younger and mild-risk patients.

Purpose: To investigate the effect of regular monitoring of pulmonary function and ventilatory status on the initiation of non-invasive ventilation (NIV) between patients who were routinely monitored before receiving NIV and those who were not. Materials and Methods: This retrospective cohort study included subjects with Duchenne muscular dystrophy (DMD) who first received NIV between 2010 and 2019. The subjects were assigned to either the regular-follow-up (REG) group or the non-REG group, according to their follow-up status, before initiating NIV. We compared the number of emergent cases, the results of nocturnal ventilatory monitoring, and the pulmonary function of each group at initial ventilatory support. Results: In total, 73 subjects were enrolled in the REG group and 47 subjects in the non-REG group. There were significantly more emergency cases due to respiratory insufficiency in the non-REG group (12/47, 25.5%) than in the REG group (3/73, 4.1%). At the time of initial ventilatory support, hypoventilatory symptoms were more common and relatively severe in the non-REG group (37/47, 78.7%) than in the REG group (18/73, 24.7%). The average age at initial ventilatory support of the non-REG group was 2.15 years older than that of the subjects in the REG group. Moreover, subjects who were not regularly monitored exhibited greater deterioration in pulmonary function compared to those who were regularly followed up. Conclusion Regular evaluation of pulmonary function and ventilatory status before the onset of ventilatory insufficiency is crucial to reduce the risk of patients with DMD requiring emergency care due to ventilatory insufficiency.

Freeman-Sheldon syndrome (FSS) is a rare distal arthrogryposis syndrome. There are few reports on the respiratory insufficiency of FSS. Additionally, there is no detailed information on pulmonary functional evaluation. A 17-year-old male patient with FSS developed respiratory failure, leading him to be admitted to hospital several times for evaluation and treatment. Of those times he was admitted, two were due to pneumonia. His pulmonary functions were indicative of a restrictive lung disease potentially caused by severe scoliosis. After a non-invasive ventilatorwas applied correctly to the patient, pulmonary hypertension was normalized. His pulmonary function has been maintained for 13 years. Since receiving proper respiratory care, which includes assisted coughing methods, the patient has not developed pneumonia. It is important to properly evaluate the pulmonary function of patients who have FSS and scoliosis to eliminate the risk of long-term respiratory complications.

PURPOSE: Type II endoleaks (T2ELs) are the most common type of endoleaks observed after endovascular aneurysm repair (EVAR). However, whether T2ELs should be treated remains debatable. In the present study, we aimed to describe the natural course of T2ELs and suggest the direction of their management. MATERIALS AND METHODS: We reviewed the data of 383 patients who underwent EVAR between 2007 and 2016. Data, including demographic and anatomical details, were collected, and patients with T2ELs were compared to those without them. Patients with T2ELs were categorized into subgroups according to changes in sac size and treatment requirement. RESULTS: We found patent lumbar artery count and lesser thickness of mural thrombi to be significant risk factors for T2ELs. Among the 383 patients, 85 (22.2%) patients were diagnosed with pure T2ELs. Among these 85 patients, the sac size increased in 29 (34.1%) patients, showed no significant change in 39 (45.9%) patients, and decreased in 17 (20.0%) patients. Fifteen (17.6%) patients, among 85 with initial pure T2ELs, showed spontaneous resolution. Five (5.9%) patients among 29, in whom the sac size increased, developed combined-type endoleaks. No sac ruptures were noted among the patients with T2ELs. CONCLUSION: T2ELs with sac expansion potentially contribute to other types of endoleaks. Therefore, periodic screening is important for these patients, particularly for those showing an increasing sac size. In addition, intervention should be considered when other types of endoleaks occur.

OBJECTIVE: To evaluate pulmonary functions of patients with amyotrophic lateral sclerosis (ALS), Duchenne muscular dystrophy (DMD), and myotonic muscular dystrophy (MMD) at the onset of ventilatory insufficiency. METHODS: This retrospective study included ALS, DMD, and MMD patients with regular outpatient clinic follow-up in the Department of Rehabilitation Medicine at Gangnam Severance Hospital before the application of non-invasive positive pressure ventilation (NIPPV). The patients were enrolled from August 2001 to March 2014. If patients experienced ventilatory insufficiency, they were treated with NIPPV, and their pulmonary functions were subsequently measured. RESULTS: Ninety-four DMD patients, 41 ALS patients, and 21 MMD patients were included in the study. The mean SpO2 was lower in the MMD group than in the other two groups. The mean forced vital capacity (FVC) in the supine position was approximately low to mid 20% on average in DMD and ALS patients, whereas it was 10% higher in MMD patients. ALS patients showed a significantly lower FVC in the supine position than in the sitting position. Maximal insufflation capacity, unassisted peak cough flow, maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP) were significantly higher in MMD group than in the other groups. MEP was significantly the lowest in DMD patients, followed by in ALS, and MMD patients, in order. CONCLUSION: Disease-specific values of pulmonary function, including FVC, MEP, and MIP, can be accurately used to assess the onset of ventilatory insufficiency in patients with ALS, DMD, and MMD.
