    Analysis of factors affecting the diagnostic yield for microbiologic diagnosis from percutaneous abdominal abscess drainage
    (J Infection Developing Countries, 2024) Arslan, Muhammet; Aslan, Halil S.; Tekinhatun, Muhammed; Ozgen, Utku; Sari, Tugba
    Introduction: This study aimed to investigate the factors influencing the diagnostic yield of microbiologic diagnosis obtained through percutaneous abdominal abscess drainage procedures. We analyzed the influence of diverse clinical, radiological, and pre-procedural factors on the success of microbiologic diagnosis in this context. Methodology: A retrospective analysis of patients who underwent percutaneous abdominal abscess drainage was performed to assess the factors affecting the diagnostic yield for microbiologic diagnosis. Results: A total of 174 patients undergoing percutaneous abdominal abscess drainage was included. The use of antibiotics during the procedure and the spread of the abscess to other organs significantly increased the likelihood of obtaining a positive culture. Specifically, antibiotic use during the procedure raised the risk by up to 3.30-fold (OR = 3.30, 95% CI 1.48-7.65, p = 0.004), while abscess spread to another organ increased the risk by approximately 1.87-fold (OR = 1.87, 95% CI 0.98-3.61, p = 0.057). Additionally, abscesses containing air and abscesses with an air-fluid level were more common in patients with positive culture results. Other factors, such as gender, age, malignancy prevalence, and surgical history, did not significantly impact culture results. Conclusions: This study provides valuable insights into the factors affecting the diagnostic yield of microbiologic diagnosis from percutaneous abdominal abscess drainage. The findings underscore the importance of considering patient-specific variables and procedural aspects when planning and executing abscess drainage procedures. Further research can build upon these insights to develop evidence-based guidelines for optimizing the diagnostic yield of percutaneous abdominal abscess drainage procedures.

    Complications of imaging-assisted port catheters and factors affecting complications
    (Pamukkale University, 2024) Tekinhatun, Muhammed; Arslan, Muhammet; Aslan, Halil Serdar; Yavaş, Hüseyin Gökhan; Demirci, Mahmut; Koluman, Başak Ünver; Alver, Kadirhan
    Purpose: This research investigates complications associated with Imaging-Assisted Port Catheters (IAPCs) to provide insights for healthcare professionals involved in their usage. The study aims to optimize patient safety, implement preventive strategies, and guide evidence-based decision-making in the clinical use of IAPCs. Materials and methods: A retrospective study comprising 1247 patients who underwent IAPC placement in the Interventional Radiology Unit between 01.09.2012-01.09.2020 was conducted. Data, including indications for port placement, complications, duration of port stay, and reasons for explantation, were extracted from electronic medical records. Comparative analysis with surgically implanted ports was performed, and the efficacy and safety of imaging-guided port implantation were assessed. Results: The study predominantly involved right internal jugular vein placement (93.8%). Major complications did not occur during the 7 to 1330 days of port usage. The average usage period was 243 days, totaling 310,503 catheter-days. Infectious complications were the most common (4.8%), significantly higher (13.9%) in hematological malignancies. Multivariate analysis revealed a significantly increased complication rate in hematological malignancy patients (p<0.001). Conclusion: The research reveals an 8.6% overall incidence of complications in IAPC usage, with hematologic malignancy identified as a significant independent risk factor. The low complication rate per 1000 catheter days (0.36) aligns with recent studies, emphasizing the benefits of image guidance and procedural expertise. Notably, infectious complications, especially in hematologic malignancy patients, underscore the need for further research to refine IAPC management for long-term intravenous access. The study contributes essential insights for healthcare professionals involved in the field, emphasizing ongoing efforts in advancing IAPC management for the benefit of patients.

    Is a two-hour monitoring period sufficient and safe for patients undergoing ultrasound-guided percutaneous liver mass biopsy?: A prospective and multicenter experience
    (Wiley, 2024) Aslan, Halil Serdar; Arslan, Muhammet; Alver, Kadir Han; Demirci, Mahmut; Korkmaz, Mehmet; Esen, Kaan; Turmak, Mehmet
    PurposeTo investigate whether patients undergoing percutaneous liver mass biopsy (PLMB) can be safely discharged following a two-hour monitoring period.MethodsA multi-center prospective analysis was conducted for 375 patients (196 males and 179 females), mean age 63 +/- 12.45 years (range 37-89) who underwent PLMB between August 2023 and March 2024. Patients were monitored for 24 h, and complications were classified as minor or major. The timing of complications was categorized into three groups: within the first two hours, between the 2nd and 24th hours, and within 1 week after 24 hours.ResultsMinor complications occurred in 18.93% (71/375) and major complications in 2.13% (8/375). Most minor complications (80.2%, 57/71) appeared within the first two hours, 12.7% (9/71) between 2 and 24 h, and 7.1% (5/71) after 24 h. All major complications (62.5%, 5/8) except late-onset cases, occurred within the first two hours. No major complications occurred between 2 and 24 h. Late-onset major complications occurred in 37.5% (3/8) after 24 h.ConclusionThe two-hour monitoring period did not adversely impact patient management regarding minor complications and is safe for identifying all major complications except for late-onset ones. Extending the post-biopsy recovery period does not significantly improve patient care. A two-hour observation period after PLMB, including hemogram monitoring and ultrasound, does not adversely affect patient management regarding minor complications and is safe and efficient for detecting significant complications except delayed ones. Extending recovery time does not significantly improve patient care, as delayed complications appear later. image

    Role of Superb Microvascular Imaging (SMI) vascularity index values and vascularity patterns in the differential diagnosis of malignant liver lesions
    (Springer, 2024) Aslan, Halil Serdar; Arslan, Muhammet; Alver, Kadir Han; Vurgun, Sercan; Demirci, Mahmut; Tekinhatun, Muhammed
    PurposeTo evaluate the Superb Microvascular Imaging (SMI) vascular patterns and vascularity index (VI) values of malignant focal liver lesions (FLLs), assess their role in differential diagnosis, and examine interobserver agreement.Materials and methodsA total of 107 patients (52 males, 55 females; mean age 62 +/- 12.8 years, range 25-87) referred to the interventional radiology clinic for FLL biopsy between April 2022 and April 2023 were analyzed. Two radiologists independently assessed the SMI vascular patterns and calculated VI values. Differences among three lesion groups - hepatocellular carcinoma (HCC, n = 16), non-HCC primary liver malignancies (n = 16), and metastases (n = 75) - were evaluated, and interobserver agreement was assessed.ResultsMost metastases (88%) demonstrated hypovascular patterns, while HCCs predominantly exhibited hypervascular patterns (68.7-81.3%). Non-HCC primary malignancies showed no dominant vascular pattern. Significant differences in SMI patterns were observed among lesion types (p = 0.001-0.035). VI values for HCCs (7.53-7.73) were significantly higher than those for non-HCC malignancies (2.73-2.93) and metastases (1.35-1.36) (p = 0.0001). ROC analysis based on VI values yielded AUCs of 0.886-0.887, with a cutoff of 2.92 providing 81.3% sensitivity and 79.1-80.2% specificity for HCC diagnosis. The inter-reader agreement for SMI patterns had a kappa score of 0.634, while the intraclass correlation coefficient (ICC) for VI values was 0.959.ConclusionHCCs displayed more hypervascular SMI patterns and significantly higher VI values compared to other malignant FLLs, emphasizing the diagnostic potential of VI in distinguishing HCC from non-HCC tumors. Although metastases primarily exhibited hypovascular patterns and low VI values, no dominant vascular pattern was identified in non-HCC primary liver malignancies. Assessing VI values provided higher interobserver agreement compared to SMI patterns, enhancing objectivity and reproducibility.
