Genetic variants in key necroptosis regulators predict prognosis of non-small cell lung cancer after surgical resection. Thorac Cancer 2023; 14:2678-2686. [PMID: 37519036 PMCID: PMC10493482 DOI: 10.1111/1759-7714.15054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 07/12/2023] [Accepted: 07/14/2023] [Indexed: 08/01/2023] Open
Abstract
BACKGROUND Necroptosis is a regulated inflammatory cell death which plays a significant role in cancer development and progression. In this study, we evaluated whether genetic variants in key regulators of necroptosis may affect survival outcome of non-small cell lung cancer (NSCLC) patients after surgical resection. METHODS A total of 674 patients who underwent curative surgery were included. Fifteen genetic variants in key regulators of necroptosis (RIPK1, RIPK3, and MLKL) were selected. The association of these variants with survival outcomes was evaluated. RESULTS Two variants, RIPK1 rs17548629C > T and MLKL rs877375G > C, were associated with better overall survival and disease-free survival in multivariate analyses. When the patients were divided according to histology, the associations were significant only in adenocarcinoma, but not in squamous cell carcinoma. RIPK1 rs17548629 C-to-T change was associated with significantly increased luciferase activity by modulating the binding of miR-642a. Promoter assays showed a significantly increased promoter activity in MLKL rs877375C allele compared to G allele. Consistently, the mRNA expression level of RIPK1 and MLKL showed significant positive correlation with RIPK1 rs17548629C-to-T and MLKL rs877375G-to-C changes. CONCLUSION Two genetic variants in key regulators in necroptosis, RIPK1 rs17548629C > T and MLKL rs877375G > C, may be used as biomarkers to predict survival outcomes in surgically resected NSCLC patients.

Lipid Metabolism Pathway Genes and Lung Cancer: ACADSB rs12220683G>C Is Associated with Better Survival Outcome in Patients with Non-Small Cell Lung Cancer. Oncology 2023; 102:67-75. [PMID: 37527640 DOI: 10.1159/000533156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 07/14/2023] [Indexed: 08/03/2023]
Abstract
INTRODUCTION Altered lipid metabolism has been reported to be associated with prognosis in multiple cancers. This study aimed to investigate the association of polymorphisms in lipid metabolism pathway genes with survival outcomes in patients with surgically resected non-small cell lung cancer (NSCLC). METHODS In total, 744 patients with surgically resected NSCLC (380 in the discovery cohort and 364 in the validation cohort) were included in this study. The association between 176 polymorphisms of lipid metabolism pathway genes and the clinical outcomes of NSCLC patients was analyzed. RESULTS Among the polymorphisms investigated, ACADSB rs10902859G>A was associated with significantly better overall survival (OS) in the discovery, validation, and combined cohorts. ACADSB rs10902859G>A was located in the repressed region and had strong linkage disequilibrium (D' = 1.00 and r2 = 0.94), with rs12220683G>C located in the H3K4me3 peak region, which indicates the presence of active promoters. ACADSB rs12220683G>C was also associated with better OS in the discovery, validation, and combined cohorts (in a dominant model; adjusted hazard ratio [aHR] = 0.53, 95% confidence interval [CI] = 0.30-0.94, p = 0.03; aHR = 0.37, 95% CI = 0.15-0.89, p = 0.03; and aHR = 0.47, 95% CI = 0.29-0.75, p = 0.002, respectively). In vitro luciferase assay demonstrated that the promoter activity of ACADSB was significantly increased in the rs12220683 variant C allele compared with that in the wild G allele (p = 3 × 10-5). CONCLUSION These results suggest that ACADSB rs12220683G>C increases promoter activity and that increased ACADSB expression may result in better OS in patients with surgically resected NSCLC.

Ultrasound-guided lung biopsy for small (≤2 cm) subpleural lung lesions: comparison of diagnostic yield and safety with larger lesions. J Thorac Dis 2023; 15:2485-2496. [PMID: 37324103 PMCID: PMC10267907 DOI: 10.21037/jtd-22-1546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 03/17/2023] [Indexed: 06/17/2023]
Abstract
Background Ultrasound (US)-guided percutaneous core needle biopsy (PCNB) has been used to diagnose subpleural lung lesions with high diagnostic performance and acceptable complication rates. However, with regard to the role of US-guided needle biopsy for the diagnosis of small (≤2 cm) subpleural lesions, limited information is available. Methods From April 2011 to October 2021, a total of 572 US-guided PCNBs in 572 patients were retrospectively reviewed. The lesion size, pleural contact length (PCL), lesion location, and operator's experience were analyzed. Computed tomography features including peri-lesional emphysema, air-bronchogram, and cavitary change were also included in image analysis. The patients were divided into three groups according to lesion size (lesions ≤2 cm vs. 2 cm< lesions ≤5 cm vs. lesions >5 cm). The sample adequacy, diagnostic success rate, diagnostic accuracy, and complication rate was calculated. For statistical analysis, one-way ANOVA, Kruskal-Wallis test, or the chi-square test were used. Results The overall sample adequacy, diagnostic success rate, and diagnostic accuracy were 96.2%, 82.9%, and 90.4%, respectively. In the subgroup analysis, sample adequacy (93.1% vs. 96.1% vs. 96.9%, P=0.307), diagnostic success rate (75.0% vs. 81.6% vs. 85.7%, P=0.079), and diagnostic accuracy (84.7% vs. 90.8% vs. 90.5%, P=0.301) were not significantly different. Operator's experience (OR, 0.64; 95% CI: 0.49-0.80; P<0.001), lesion size (OR, 0.68; 95% CI: 0.54-0.83; P<0.001), PCL (OR, 0.68; 95% CI: 0.52-0.84; P=0.001), and presence of air-bronchogram (OR, 14.36; 95% CI: 4.18-48.53; P<0.001) were independently associated with complication rate. Conclusions US-guided PCNB performed by an experienced radiologist could be an effective and safe diagnostic approach for subpleural lesions, even in small lesions.

Peritumoral imaging features of thymic epithelial tumors for the prediction of transcapsular invasion: beyond intratumoral analysis. Diagn Interv Radiol 2023; 29:109-116. [PMID: 36960547 PMCID: PMC10679598 DOI: 10.4274/dir.2022.21803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 04/25/2022] [Indexed: 01/15/2023]
Abstract
PURPOSE The purpose of this study was to differentiate cases without transcapsular invasion (Masaoka-Koga stage I) from cases with transcapsular invasion (Masaoka-Koga stage II or higher) in patients with thymic epithelial tumors (TETs) using tumoral and peritumoral computed tomography (CT) features. METHODS This retrospective study included 116 patients with pathological diagnoses of TETs. Two radiologists evaluated clinical variables and CT features, including size, shape, capsule integrity, presence of calcification, internal necrosis, heterogeneous enhancement, pleural effusion, pericardial effusion, and vascularity grade. Vascularity grade was defined as the extent of peritumoral vascular structures in the anterior mediastinum. The factors associated with transcapsular invasion were analyzed using multivariable logistic regression. In addition, the interobserver agreement for CT features was assessed using Cohen's or weighted kappa coefficients. The difference between the transcapsular invasion group and that without transcapsular invasion was evaluated statistically using the Student's t-test, Mann-Whitney U test, chi-square test, and Fisher's exact test. RESULTS Based on pathology reports, 37 TET cases without and 79 with transcapsular invasion were identified. Lobular or irregular shape [odds ratio (OR): 4.19; 95% confidence interval (CI): 1.53-12.09; P = 0.006], partial complete capsule integrity (OR: 5.03; 95% CI: 1.85-15.13; P = 0.002), and vascularity grade 2 (OR: 10.09; 95% CI: 2.59-45.48; P = 0.001) were significantly associated with transcapsular invasion. The interobserver agreement for shape classification, capsule integrity, and vascularity grade was 0.840, 0.526, and 0.752, respectively (P < 0.001 for all). CONCLUSION Shape, capsule integrity, and vascularity grade were independently associated with transcapsular invasion of TETs. Furthermore, three CT TET features demonstrated good reproducibility and help differentiate between TET cases with and without transcapsular invasion.

Genetic variants in LKB1/AMPK/mTOR pathway are associated with clinical outcomes of chemotherapy in non-small cell lung cancer. Thorac Cancer 2022; 13:3322-3330. [PMID: 36239337 PMCID: PMC9715851 DOI: 10.1111/1759-7714.14688] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 09/26/2022] [Accepted: 09/28/2022] [Indexed: 02/02/2023] Open
Abstract
This study was conducted to investigate the relationship between genetic variants in LKB1/AMPK/mTOR pathway and treatment outcomes of patients with non-small cell lung cancer (NSCLC) treated with chemotherapy. A total of 379 patients with NSCLC who underwent first-line paclitaxel-cisplatin chemotherapy was enrolled. The associations between 19 single nucleotide variants (SNVs) in the LKB1/AMPK/mTOR pathway and the chemotherapy response and overall survival (OS) were analyzed. Among the SNVs analyzed, AKT1 rs2494750G>C and TSC1 rs2809244C>A were associated with clinical outcomes after chemotherapy in multivariate analyses. The AKT1 rs2494750G>C was significantly associated with a better response to chemotherapy (adjusted odds ratio [aOR]: 1.92, 95% confidence interval [CI]: 1.02-3.62, p = 0.04). The TSC1 rs2809244C>A were significantly associated with better OS (adjusted hazard ratio [aHR]: 0.79, 95% CI: 0.62-0.99, p = 0.04). When stratified by tumor histology, AKT1 rs2494750G>C exhibited a significant association with the chemotherapy response only in adenocarcinoma and TSC1 rs2809244C>A was also significantly associated with OS only in adenocarcinoma. This result suggests that the AKT1 rs2494750G>C and TSC1 rs2809244 C>A may be useful for predicting the clinical outcome of first-line paclitaxel-cisplatin chemotherapy in NSCLC.

Abstract
BACKGROUND Activating transcription factor 3 (ATF3) plays a significant role in cancer development and progression. We investigated the association between variants in expression quantitative trait loci (eQTLs) within ATF3 binding regions and the prognosis of non-small cell lung cancer (NSCLC) after surgery. METHODS A total of 772 patients with NSCLC who underwent curative surgery were enrolled. Using a public database (http://galaxyproject.org), we selected 104 single nucleotide polymorphisms (SNPs) in eQTLs in the ATF3 binding regions. The association of those SNPs with disease-free survival (DFS) was evaluated. RESULTS Among those SNPs, HAX1 rs11265425T>G was associated with significantly worse DFS (aHR = 1.30, 95% CI = 1.00-1.69, p = 0.05), and ME3 rs10400291C>A was associated with significantly better DFS (aHR = 0.66, 95% CI = 0.46-0.95, p = 0.03). Regarding HAX1 rs11265425T>G, the significant association remained only in adenocarcinoma, and the association was significant only in squamous cell carcinoma regarding ME3 rs10400291C>A. ChIP-qPCR assays showed that the two variants reside in active enhancers where H3K27Ac and ATF3 binding occurs. Promoter assays showed that rs11265425 G allele had significantly higher HAX1 promoter activity than T allele. HAX1 RNA expression was significantly higher in tumor than in normal lung, and higher in rs11265425 TG+GG genotypes than in TT genotype. Conversely, ME3 expression was significantly lower in tumor than in normal lung, and higher in rs10400291 AA genotype than in CC+CA genotypes. CONCLUSIONS In conclusion, this study shows that the functional polymorphisms in ATF3 binding sites, HAX1 rs11265425T>G and ME3 rs10400291C>A are associated with the clinical outcomes of patients in surgically resected NSCLC.

Clinical implication of minimal presence of solid or micropapillary subtype in early-stage lung adenocarcinoma. Thorac Cancer 2020; 12:235-244. [PMID: 33231358 PMCID: PMC7812076 DOI: 10.1111/1759-7714.13754] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 11/04/2020] [Accepted: 11/08/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND We investigated the clinical features and surgical outcomes of lung adenocarcinoma with minimal solid or micropapillary (S/MP) components, with a focus on stage IA. METHODS We enrolled 506 patients with lung adenocarcinoma who underwent curative resection in this study. Clinical features and surgical outcomes were compared between the groups with and without the S/MP subtype (S/MP+ and S/MP-, respectively), and between the group with an S/MP proportion of ≤5% (S/MP5) and the S/MP-. RESULTS The S/MP subtype was present in 247 patients (48.8%); 129 (25.5%) were grouped as the S/MP5 group. The S/MP+ and S/MP5 groups had larger tumors, higher frequency of lymph node metastasis, and more advanced stages of disease than the S/MP- group (P < 0.001, all comparisons). Pleural, lymphatic, and vascular invasions occurred more frequently in the S/MP+ and S/MP5 groups (P < 0.001, all comparisons for S/MP+ vs. S/MP-; P ≤ 0.01, all comparisons for S/MP5 vs. S/MP-). The S/MP+ and S/MP5 groups showed a shorter time to recurrence and cancer-related death than the S/MP- group(P < 0.001, both comparisons). For stage I, the presence or absence of the S/MP subtype defined prognostic subgroups better than the stage IA/IB classification. Notably, in the multivariate analysis, the minimal S/MP component was a significant predictor of recurrence, even in stage IA. CONCLUSIONS The presence of the minimal S/MP component was a significant predictor of poor prognosis after surgery, even in stage IA patients. Clinical trials to evaluate the advantages of adjuvant chemotherapy for this subset of patients and further investigations to understand underlying biological mechanisms of poor prognosis are needed. KEY POINTS Significant findings of the study: We demonstrated that only minimal presence of solid or micropapillary component was profoundly associated with aggressive clinicopathological features and poor prognosis after complete resection even in stage IA lung adenocarcinoma. WHAT THIS STUDY ADDS Our results suggest that minimal presence of these subtypes is a strong prognostic factor which should be taken into account in the risk assessment for adjuvant chemotherapy in lung adenocarcinoma.

Abstract
BACKGROUND This study was conducted to investigate the association between genetic variants in one-carbon metabolism and survival outcomes of surgically resected non-small cell lung cancer (NSCLC). METHODS We genotyped 41 potentially functional variants of 19 key genes in the one-carbon metabolism pathway among 750 NSCLC patients who underwent curative surgery. The association between genetic variants and overall survival (OS)/disease-free survival (DFS) were analyzed. RESULTS Among the 41 single-nucleotide polymorphisms (SNPs) analyzed, 4 SNPs (MTHFD1L rs6919680T>G and rs3849794T>C, MTR rs2853523C>A, and MTHFR rs4846049G>T) were significantly associated with survival outcomes. MTHFD1L rs6919680T>G and MTR rs2853523C>A were significantly associated with better OS (adjusted hazard ratio [aHR] = 0.73, 95% confidence interval [CI] = 0.54-0.99, p = 0.04) and worse OS (aHR = 2.14, 95% CI = 1.13-4.07, p = 0.02), respectively. MTHFD1L rs3849794T>C and MTHFR rs4846049G>T were significantly associated with worse DFS (aHR = 1.41, 95% CI = 1.08-1.83, p = 0.01; and aHR = 1.97, 95% CI = 1.10-3.53, p = 0.02, respectively). When the patients were divided according to histology, the associations were significant only in squamous cell carcinoma (SCC), but not in adenocarcinoma (AC). In SCC, MTHFD1L rs6919680T>G and MTR rs2853523C>A were significantly associated with better OS (aHR = 0.64, 95% CI = 0.41-1.00, p = 0.05) and worse OS (aHR = 2.77, 95% CI = 1.11-6.91, p = 0.03), respectively, and MTHFD1L rs3849794T>C and MTHFR rs4846049G>T were significantly associated with worse DFS (aHR = 1.73, 95% CI = 1.17-2.56, p = 0.01; and aHR = 2.78, 95% CI = 1.12-6.88, p = 0.03, respectively). CONCLUSIONS Our results suggest that the genetic variants in the one-carbon metabolism pathway could be used as biomarkers for predicting the clinical outcomes of patients with early-stage NSCLC.

Characteristics and survival impact of polymorphonuclear leucocyte-predominant malignant pleural effusions secondary to lung cancer. THE CLINICAL RESPIRATORY JOURNAL 2020; 14:772-779. [PMID: 32294312 DOI: 10.1111/crj.13195] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 01/13/2020] [Accepted: 04/07/2020] [Indexed: 12/12/2022]
Abstract
INTRODUCTION In comparison with mononuclear leucocyte (MNL)-predominant malignant pleural effusions (MPEs), polymorphonuclear leucocyte (PMNL)-predominant MPEs have rarely been investigated and may be associated with a poorer prognosis. OBJECTIVES To investigate the characteristics and survival impact of PMNL-predominant MPEs secondary to lung cancer. METHODS This retrospective study included patients with MPE secondary to lung cancer, which were classified into the PMNL- and MNL-predominant groups according to cellular predominance in the pleural fluid. Clinical, hematological, radiological, and pleural fluid data were compared between the groups, and the survival impact of PMNL predominance in MPE was evaluated. RESULTS Of the 193 MPEs included, 37 (19%) were characterised by PMNL predominance. Compared to the MNL-predominant group, the PMNL-predominant group showed significantly poorer patient performances (P = .001), higher white blood cell counts (P = .009), higher neutrophil counts, higher blood neutrophil-to-lymphocyte ratio (P = .046), higher serum C-reactive protein (P = .003), lower serum albumin (P < .001), lower pleural fluid pH (P = .002) and higher pleural fluid lactate dehydrogenase (P = .029) levels. In contrast, most clinical and radiological findings, including the duration of symptoms, showed no significant intergroup differences. A shift towards MNL predominance was observed in only 38% of the PMNL-predominant patients who underwent repeat thoracentesis. Overall survival of the PMNL-predominant group was significantly shorter than the MNL-predominant group (P = .003). CONCLUSIONS PMNL predominance in MPEs secondary to lung cancer may be observed in variable phases with respect to the duration of symptoms and the time of thoracentesis. Overall, PMNL-predominant MPEs were associated with more advanced stages and poorer survival outcomes, compared to MNL-predominant MPEs.

Abstract
Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment. Early management usually includes leg elevation, drainage, and pressure dressing. However, these methods are associated with prolonged recovery and high recurrence rates. We report a case of lymphorrhea from a calf wound after endoscopic great saphenous vein (GSV) harvesting for coronary artery bypass grafting (CABG). The patient presented with intractable oozing from the postoperative wound on the right calf. Lymphorrhea perGsisted for 6 weeks despite negative-pressure wound therapy with a long-acting somatostatin. We performed unilateral pedal lymphangiography that confirmed wound lymphorrhea, followed by glue embolization. No recurrence was observed after 8 months of follow-up. This case report demonstrates the successful use of lymphangiography with glue embolization in the control of lymphorrhea after GSV harvesting for CABG.

Idiopathic Pleural Effusions: Characteristics and Discrimination From Cytology-Negative Malignant Pleural Effusions. Am J Med Sci 2020; 360:236-242. [PMID: 32423747 DOI: 10.1016/j.amjms.2020.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/10/2020] [Accepted: 04/18/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The etiology of pleural effusions often remained unknown notwithstanding surgical pleural biopsy and further clinical observation. A better understanding of clinical characteristics of patients with idiopathic pleural effusion (IPE) may improve the ability to differentiate between IPEs and cytology-negative malignant pleural effusions (MPEs) and facilitate the identification of patients requiring invasive investigation. However, little is known about the clinical factors that can help distinguish patients with IPE from those with cytology-negative MPE. MATERIALS AND METHODS Patients who were diagnosed with IPE or cytology-negative MPE between 2010 and 2017 were enrolled in this retrospective study. Clinical, laboratory and radiologic characteristics were compared between patients with IPE and cytology-negative MPE. Diagnostic performances of predictors for IPE were assessed using receiver operating characteristic curves. RESULTS Of 146 patients undergoing pleural biopsy owing to cytology-negative pleural effusion of uncertain cause, MPE was confirmed in 54 patients. IPE was ultimately diagnosed in 22 patients. Multivariate analysis demonstrated that a minimal amount of pleural effusion (odds ratio [OR] = 12.41, P = 0.039), presence of pleural nodularity (OR = 0.01, P < 0.001) and pleural fluid carcinoembryonic antigen levels less than 14 ng/mL (OR = 87.59, P = 0.002) were independent factors for distinguishing IPEs from cytology-negative MPEs. A combination of the absence of pleural nodularity with pleural fluid carcinoembryonic antigen levels less than 14 ng/mL yielded an area under the curve of 0.94 (sensitivity = 91% and specificity = 96%). CONCLUSIONS Using these readily available parameters to identify IPE in patients with cytology-negative exudative effusion of unknown cause can help guide decision-making when choosing to perform an invasive pleural biopsy or to take a conservative approach.

Abstract
BACKGROUND This study aimed to compare the postoperative analgesic effect between ultrasound-guided serratus anterior plane block (Group S, SAPB) and intercostal nerve block (Group I, ICNB) after single port video-assisted thoracoscopic surgery (S-VATS) in primary spontaneous pneumothorax. METHODS In this prospective randomized controlled study, 54 patients were randomly assigned to two groups. Patients in Group S underwent the SAPB before the surgical drape by an anesthesiologist, and in Group I, ICNBs were performed just before the wound closure after S-VATS by an attending thoracic surgeon. The primary outcome was the numeric pain rating scale (NRS) score given by the patients for pain at the surgical incision site. NRS was assessed during resting and coughing statuses at 3, 6, and 12 hours postoperatively and at the time of the chest tube removal. The secondary outcomes included the number of nonsteroidal anti-inflammatory drugs (NSAIDs) and opioid administration until time to chest tube removal. RESULTS There were no statistical differences between the two groups regarding age, body mass index, duration of operation, duration of anesthesia, and average NRS scores for the assigned time periods. There was no statistical significance in the number of opioid injections; however, NSAIDs were administered 2.8 times per patient in Group I, and 1.9 times per patient in Group S (p = 0.038). CONCLUSION In the patients who underwent S-VATS with primary spontaneous pneumothorax, the SAPB provided similar postoperative pain relief with reducing the NSAIDs consumption compared with ICNB.

Over-the-wire deployment techniques of option elite inferior vena cava filter: 3D printing vena cava phantom study. Eur J Radiol Open 2020; 7:100227. [PMID: 32258247 PMCID: PMC7096752 DOI: 10.1016/j.ejro.2020.100227] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 03/03/2020] [Accepted: 03/03/2020] [Indexed: 11/07/2022] Open
Abstract
Bent stiff-wire technique with transfemoral access had lower filter tilt ratio at Option IVC filter deployment. Original push wire with transjugular access had lower filter tilt ratio at Option IVC filter deployment. Filter jumping was common using the original push wire with transjugular access.
Purpose To compare filter tilt and filter jumping during Option inferior vena cava (IVC) filter deployment with 3 different wires techniques using a 3-dimensional (3D) printing vena cava phantom. Materials and methods An IVC 3D printed vena cava phantom was made from a healthy young male’s computed tomographic data. Option IVC filters were deployed with 3 different wires: i) original push wire, ii) hydrophilic stiff wire, and iii) bent stiff wire. Right internal jugular and right femoral access were used 5 times with each wire. Filter tilt angle, tilt ratio, jumping, and tip abutment to the IVC wall were analyzed. Results The transfemoral approach with original push wire had significantly higher tilt angle than did the transjugular approach (6.1˚ ± 1.9 vs. 3.5˚ ± 1.3, p = 0.04). Mean tilt ratio was significantly lower with the bent wire with transfemoral access (0.49 ± 0.13 vs. 0.78 ± 0.18 [original push-wire] and 0.67 ± 0.08 [stiff wire], p = 0.019). The ratio was lower also with original push wire with transjugular access (0.34 ± 0.19 vs. 0.57 ±0.11 [stiff wire] and 0.58 ±0.17 [bent wire], p = 0.045). Filter jumping occurred more often with the transjugular approach with original push wire than with stiff or bent-wire delivery. Filter tip abutment to the IVC wall occurred only with the transfemoral approach. Conclusions Bent wire with transfemoral access and original push wire with transjugular access had lower filter tilt ratio at Option IVC filter deployment. However, filter jumping was common using the original push wire with transjugular access.

Abstract
Background Thoracic aortic aneurysms, although mostly asymptomatic, are life threatening owing to the risk of rupture. Moreover, the extrinsic pressure of a ruptured aneurysm may encroach the mediastinum. Case presentation A 74-year-old woman diagnosed with ruptured descending thoracic aortic aneurysm compressing the lower trachea and both main bronchi underwent thoracic endovascular aortic repair; however, the extrinsic pressure on the airway persisted. Following failing of endobronchial silicon stents insertion, extracorporeal membrane oxygenation support was required, and endobronchial metallic stents were inserted. The patients’ hypoventilation resolved, and the patient was withdrawn from the ventilator. Conclusions Technological improvement in endovascular or endobronchial procedures has provided more options for managing complex cases. However, we must be aware of how high the extrinsic pressure might be before management and take steps to minimize complications.

Abstract
PURPOSE Thoracic endovascular aortic repair (TEVAR) for traumatic thoracic aortic injury (TTAI) reports short-term benefits. However, long-term durability and the need of reintervention remain unclear. Here, we determined mid-term outcome of TEVAR for TTAI and investigated the influence of the length of proximal landing zone on aorta. METHODS Between October 2009 and February 2018, 69 patients diagnosed TTAI and 42 included patients underwent TEVAR. Patients were divided into two groups by the length of proximal landing zone; ≤ 20 mm and > 20 mm. The primary endpoint was success and survival rate, and the secondary endpoint was the increase of aorta size and the need of reintervention. RESULTS The mean follow-up period was 47.9 ± 29.6 months and 100% success rate. No endoleaks or additional reinterventions during the follow-up period. The cumulative survival of all-cause death was 90.5 ± 2.3%, 85.7 ± 4.1% and 61.7 ± 8.4% at 1, 5 and 7 years, respectively. There was no statistically significant difference in the increase of aorta size due to the length of the proximal landing zone (p = 0.65). CONCLUSION In selective TTAI patients for TEVAR, the length of proximal landing zone did not considerably influence the aorta size or needed further reintervention.

Abstract
If the best treatment for a patient with a primary pulmonary tumor extending into the left atrium via the left pulmonary vein is surgical resection, it is necessary to determine the appropriate approach, that is, whether cardiopulmonary bypass (CPB) or complete resection, would be more suitable. Lung resections under CPB are rarely performed because of the unpredictable prognosis. We report two successful cases of safe and rapid complete resection of primary pulmonary malignancy extending into the left atrium with the support of CPB via median sternotomy. Our experiences support the application of CPB in extended left pulmonary resections to achieve complete resection.

Abstract
INTRODUCTION Central venous catheterization-induced central vein pseudoaneurysm is rare. Several treatment options have been recommended. We describe a case of central venous catheterization-induced right brachiocephalic vein pseudoaneurysm successfully treated with an uncovered self-expandable stent-assisted coil embolization and discuss the imaging findings, treatment strategy, and review of literature associated with thoracic venous pseudoaneurysm. CASE REPORT A 77-year-old woman was referred to our trauma center to undergo treatment for central venous catheterization-induced central vein pseudoaneurysm. The initial contrast-enhanced chest computed tomography revealed a 3.4-cm pseudoaneurysm arising from the right brachiocephalic vein and a surrounding mediastinal hematoma. The pseudoaneurysm was successfully embolized with stent-assisted coiling. Computed tomography angiography was performed 10 days after the procedure and demonstrated a completely embolized pseudoaneurysm and resolved mediastinal hematoma. Blood flow from the right subclavian and left innominate veins was not disturbed by the stent-assisted coils. CONCLUSION To our knowledge, this is the first report of treatment of a right brachiocephalic vein pseudoaneurysm with stent-assisted coil embolization. We think that uncovered stent-assisted coil embolization is the safest and most fundamental treatment for wide-neck venous pseudoaneurysm especially in a hemodynamically unstable setting.

Abstract
BACKGROUND We compared the chest configurations of patients with primary spontaneous pneumothorax (PSP) and age-sex-matched controls to determine the presence of chest wall deformities in patients with PSP. METHODS We retrospectively enrolled 166 male patients with PSP (age, 18-19 years) and 85 age-sex-matched controls without PSP, who simultaneously underwent chest computed tomography (CT) and radiography at one of two institutes. After correcting for height, the following thoracic parameters were comparatively evaluated between the two groups: maximal internal transverse (T) and anteroposterior (W) diameters of the chest, maximal internal lung height (H), Haller index (T/W), and T/Height, T/H, W/Height, W/H, and H/Height ratios. RESULTS Patients were taller than the control subjects (176.5 cm ± 5.9 cm versus 174.4 cm ± 5.6 cm; p = 0.007). After controlling for height, the patient group exhibited lower T and W and greater H and Haller index values than the control group (T: 95% confidence interval [CI], 24.8-25.2 cm versus 25.9-26.5; W: 95% CI, 8.9-9.2 cm versus 10.1-10.6 cm; H: 95% CI, 25.2-25.9 cm versus 23.4-24.4 cm; and Haller index, 95% CI, 2.7-2.9 versus 2.4-2.6; all, p < 0.001). The patient group also exhibited lower T/Height, T/H, W/Height, and W/H ratios and greater H/Height ratio than the control group. CONCLUSIONS Patients with PSP have an anteroposteriorly flatter, laterally narrower, and craniocaudally taller thorax than subjects without PSP, suggesting that chest configuration is associated with the development of pneumothorax.

Abstract
We report the case of a 67-year-old woman presenting with epigastric pain. Computed tomography identified diffuse phlegmonous esophagitis. Esophagogastroduodenoscopy revealed multiple perforations in the mucosal layer of the esophagus. A large amount of pus was drained internally through the gut. The patient was treated with antibiotics and early jejunostomy feeding. Although phlegmonous esophagitis is a potentially fatal disease, the patient was successfully treated medically with only a minor complication (esophageal stricture).

Abstract
BACKGROUND In lung transplantation (LTx), patients with thoracic muscle sarcopenia may have to require longer to recovery. We measured thoracic muscle volume by using the cross sectional area (CSA) and assessed its effect on early outcomes after LTx. METHODS A retrospective analysis was conducted to evaluate the effect of thoracic sarcopenia in patients undergoing LTx between January 2010 and July 2015. The lowest CSA quartile (Q1) was defined as sarcopenia. RESULTS In total, 109 patients were enrolled. The mean CSA was 58.24±15.82 cm(2). Patients in the highest CSA quartile were more likely to be male (92.6% vs. 17.9%, P<0.001), older (55.2±10.1 vs. 43.2±14.9 years, P=0.001), to have a higher body mass index (BMI) (22.3±4.0 vs. 19.4±3.7 kg/m(2), P=0.007), and to have pulmonary fibrosis (85.2% vs. 35.7%, P=0.003) compared with the lowest CSA quartile. Early outcomes including ventilator support duration [32.9±49.2 vs. 24.5±39.9 days, P= not significant (ns)], intensive care unit (ICU) stay duration (28.4±43.7 vs. 24.4±35.9 days, P= ns) and hospital stay duration (61.4±48.2 vs. 50.8±37.2 days, P= ns) tended to be longer in Q1 than Q4, but the difference was not significant. However, the 1-year survival rate was better in Q1 compared with Q4 (66.6% vs. 46.0%, P=0.04). CONCLUSIONS Although patients with thoracic sarcopenia seem to require a longer post-operative recovery time after LTx, this does not compromise their early outcomes. By contrast, patients with larger thoracic muscle volume (Q4) showed poorer survival times.

Abstract
BACKGROUND The study objective was to compare the outcomes of intraoperative routine use of venoarterial (VA) extracorporeal membrane oxygenation (ECMO) versus selective use of cardiopulmonary bypass (CPB). METHODS Between January 2010 and February 2013, 41 lung transplantations (LTx) were performed, and CPB was used as a primary cardiopulmonary support modality by selective basis (group A). Between March 2013 and December 2014, 41 LTx were performed, and ECMO was used routinely (group B). The two groups were compared retrospectively. RESULTS The operative time was significantly longer in group A (group A, 458 min; group B, 420 min; P=0.041). Postoperatively, patients in group B had less fresh frozen plasma (FFP) transfusion (P=0.030). Complications were not different between the two groups. The 30- and 90-day survival rates were better in group B (30-day survival: group A, 75.6%; group B, 95.1%, P=0.012; 90-day survival: group A, 68.3%; group B, 87.8%, P=0.033). The 1-year survival showed better trends in group B, but it was not significant. Forced vital capacity (FVC) at 1, 3, and 6 months after LTx was better in group B than in group A (1 month: group A, 43.8%; group B, 52.9%, P=0.043; 3 months: group A, 45.5%; group B, 59.0%, P=0.005; 6 months: group A, 51.5%; group B, 65.2%, P=0.020). Forced expiratory volume in 1 second (FEV1) at 3 months after LTx was better in patients in group B than that in patient in group A (group A, 53.3%; group B, 67.5%, P=0.017). CONCLUSIONS Routine use of ECMO during LTx could improve early outcome and postoperative lung function without increased extracorporeal-related complication such as vascular and neurologic complications.

Abstract
Background The axillary artery is frequently used for cardiopulmonary bypass, especially in acute aortic dissection. We have cannulated the axillary artery using a side graft or by directly using Seldinger's technique. The purpose of this study was to assess the technical problems and complications of both cannulation techniques. Materials and Methods From January 2003 to December 2009, 53 patients underwent operations using the axillary artery for arterial cannulation. The axillary artery was cannulated with a side graft in 35 patients (side graft group) and directly using Seldinger's technique in 18 patients (direct group). Results The results were compared between two groups, focusing on cannulation-related morbidities including neurologic morbidity. Arterial damage or dissection of the axillary artery occurred in 1 (2.9%) patient in the side graft group and in 1 (5.6%) patient in the direct group. Malperfusion and insufficient flow did not occur in either group. There were no postoperative complications related to axillary cannulation, such as brachial plexus injury, compartment syndrome, or local wound infection, in either group. Conclusion Technical problems and complications of the axillary arterial cannulation in both techniques were rare. Direct arterial cannulation using Seldinger's technique was done safely and more simply than the previous technique. It was concluded that both axillary arterial cannulation techniques are acceptable and it remains the surgeon's preference which technique should be used.
