Assessement of the Complications of Ultrasound and Fluoroscopy-Guided Placement of Totally Implantable Venous Access Ports
(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Özkaçmaz, S.; Alpaslan, M.; Dadalı, Y.; Yavuz, A.
Totally implantable venous access systems are widely used in oncology; however, their complications are extremely common which, sometimes, require device removal, thereby, leading to delayed chemotherapy and infusion therapies. In this study, we aimed to investigate the immediate, early, and late complications of venous port implantation in our oncology patients. A total of 219 consecutive cancer patients (111 males, 108 females; mean age: 56.9 years; range: 1 to 81 years) were retrospectively analyzed between January 2013 and June 2014. A total of 220 ultrasound-and fluoroscopy-guided totally implantable venous port systems were implanted through the right or left internal jugular vein access. The mean follow-up was 83.7 (range: 2 to 410) days. Overall complication rate was 8.6% (19/220). Eight devices in seven patients were removed due to complications. Two ports were removed in one patient. The complications which required port removal were compromised port-related bloodstream infection (n=5), central venous thrombosis (n=3), and catheter thrombosis (n=1). No major complication or no mortality associated with the port implantation was seen during follow-up. Totally seven immediate complications including local hematoma (n=2), catheter tip retraction (n=2), pain (n=1), catheter loop formation (n=1), catheter malposition (n=1), two early complications (n=2; 1 wound dehiscence, and 1 wound infection), and 10 late complications including catheter-related blood stream infection (n=5), central venous thrombosis (n=3), catheter thrombosis (n=1), and tunnel hematoma (n=1) occurred. Low incidence of complications suggest ultrasound-and fluoroscopy-guided venous port implantation is a safe and reliable method for long-term venous access © 2019, Yuzuncu Yil Universitesi Tip Fakultesi.

Computed Tomography and Pet/Ct Features of Pulmonary Hamartomas
(Tabriz University of Medical Sciences, 2021) Dadalı, Y.; Özkaçmaz, S.; Özmen, Ö.; Demirağ, F.
Introduction: In this study, we aimed to examine the computed tomography (CT) and 18F-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG PET/ CT) findings of the pulmonary hamartomas. Methods: Following surgical excisional, transbronchial, or transthoracic biopsy, histopathologically proven pulmonary hamartomas were retrospectively reviewed between 2007 and 2013. The CT and PET/CT images were interpreted regarding the lesion diameter, number, location, components, and standardized uptake values (SUVmax). Results: A total of 22 hamartomas including 2 endobronchial and 20 parenchymal hamartomas were detected in 21 patients (11 males and 10 females). Among them, one patient had both endobronchial and parenchymal lesions. Right lung involvement (63.7%) was more common than left lung (36.4%) and upper lobes involvement (50%) than lower lobes (25%). Of all lesions, 54.5% had smooth margins while 40.9% had lobulated contour and 4.5% had irregular margins. Fat density was observed in 54.5% and calcification in 40.9%. In 18.2% of the lesions neither fat density nor calcification was seen. There was no FDG uptake in 5 lesions. Mean SUVmax value was 1.6±1.0 (range between 0 and 3,2). A SUVmax value > 2.5 was observed in 5 lesions. Conclusion: Our results were generally consistent with previous reports, but we found a higher female/male ratio and a more common upper lobes involvement of pulmonary hamartomas. © 2021 The Author(s).

(Tabriz University of Medical Sciences, 2021) Özkaçmaz, S.; Özgökçe, M.; Akıncı, M.B.; Durmaz, F.; Dündar, İ.; Göya, C.; Sayır, F.
Introduction: Bronchopulmonary sequestration is a rare congenital abnormality of the lung that has two different types as intralobar and extralobar. In this study, we aimed to present six cases of intralobar sequestration with atypical findings in terms of feeding, drainage, and localization. Methods: Patients diagnosed with intralobar pulmonary sequestration in our clinic between 2015 and 2019 were evaluated retrospectively. Demographical features and atypical computed tomography (CT) findings of the patients were presented by literature. Results: Among 45 patients with intralobar sequestration, 6 (13.3%) (5 males and 1 female) with a mean age of 43.5±25.4(0-78) years old had atypical pulmonary findings on CT images. Atypical features regarding arterial supply was detected in 8.9%, venous drainage in 2.2%, location in 4.4%, radiological appearance in 4.4% and co-existing lesion in 2.2% of the patient with intralobar sequestration. Conclusion: Typical and atypical features of pulmonary sequestration must be well-known for differential diagnosis of solid or cystic pulmonary lesions. © 2021 The Author(s).
Detection of Incidental Findings on Chest Ct Scans in Patients With Suspected Covid-19 Pneumonia
(Yuzuncu Yil Universitesi Tip Fakultesi, 2021) Dündar, İ.; Özkaçmaz, S.; Durmaz, F.; Çoban, L.T.; Aygün, G.; Yıldız, R.; Türkoğlu, S.
This study aimed to evaluate the chest Computed Tomography (CT) scans of COVID-19 suspected patients in the first period of the pandemic, to reveal the frequency of parenchymal-extraparenchymal incidental findings (IFs). Our single-center retrospective observational study was initiated with the approval of the ethics committee. Chest CT records taken during March-August 2020 due to the suspicion of COVID-19 pneumonia were scanned using the imaging archive of our center. The study was conducted with 1540 patients with non-contrast chest CT without prior CT imaging to detect IFs. Histopathological results and clinical-radiological follow-up data of the patients were scanned from medical records. Of the 1540 patients in our study, 902 (58.57%) were male and 638 (41.43%) were female, with a mean age of 41.96±17.08 (5-92) years. While 248 (16.1%) patients had a typical appearance for COVID-19 pneumonia on thorax CT, no findings were found in 1180 (76.6%) patients. Except for COVID-19 pneumonia, parenchymal IFs(primary malignant lung lesions, metastatic lesions, benign pathologies) were detected in 73 patients (4.74%) and extraparenchymal IFs(lymphadenopathy, breast lesions, thyroid nodule, bone, liver and kidney lesions…) in 280 patients (18.8%). Our study showed that the number of patients without any findings in terms of COVID-19 pneumonia on CT scans is high. It is understood that CT scans for pneumonia are unnecessary due to radiation exposure and should be used when clinically necessary. However, due to the ability of CT to detect incidental findings, it is also important to define IFs oth er than pneumonia in patients who underwent chest CT examination during the pandemic. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi.

Pneumothorax and Pulmonary Hemorrhage Frequency and Risk Factors of Computed Tomography-Guided Transthoracic Pulmonary Biopsy Complications
(Tabriz University of Medical Sciences, 2023) Dadali, Y.; Özkaçmaz, S.; Çalikoǧlu, Ü.
Introduction: We aimed to analyze the frequency and risk factors of pneumothorax and pulmonary hemorrhage caused by Computed Tomography (CT) guided needle biopsy. Methods: Demographical features, pneumothorax and pulmonary hemorrhage frequencies/risk factors, characteristics of lesions of patients who underwent a CT-guided lung biopsy in our institution between January 2013 and August 2013 were reviewed retrospectively. The lesions were classified to the groups as nodular lesions ≤ 3 cm in diameter, nodular lesions > 3 cm and consolidated lesions. Pneumothorax and pulmonary hemorrhage frequencies among groups were compared using a chi-square test. A p < 0.05 was accepted as statistically significant. Results: A total number of 122 patients with a mean age of 61 ± 13 (19-88) years were included. 28 (23%) patients were female and 94 (77%) were male. 30 (24%) lesions were nodular lesions ≤ 3 cm in diameter, 57 (47%) were nodular lesions > 3 cm, and 35 (29%) were consolidated lesions. Pneumothorax developed in 15 (12%) patients while a chest tube insertion was required in 4 (3%) of them. Pulmonary hemorrhage occurred in 14 (11%) patients. Hemoptysis and hemothorax were not observed in this study. Pleura-based lesions was significantly less associated with pneumothorax when compared with ones far from pleura (P < 0.001). Usage of 17-gauge needle was significantly more associated with pneumothorax than 19-gauge (p:0.048). Pulmonary hemorrhage was significantly less observed during the biopsy of lesions > 3 cm than < 3 cm (P < 0.001). Conclusion: Nodular lesions ≤ 3 cm, location far from pleura and usage of 17-gauge needle tend to be associated with more frequent lung biopsy complications. © 2023 The Author(s).
Radiological Appearance of Hiatal Hernias on Computed Tomography
(Yuzuncu Yil Universitesi Tip Fakultesi, 2022) Ayyildiz, V.A.; Özgökçe, M.; Türkoğlu, S.; Dündar, I.; Durmaz, F.; Özkaçmaz, S.; Türko, E.
A hiatal hernia is the herniation of organs and structures in the abdominal cavity through the esophageal opening of the diaphragm. We aimed to present the tomographic findings of hiatal hernia types. The computed tomography (CT) images and demographic characteristics of the patients diagnosed with hiatal hernias based on contrast-enhanced and/or non-contrast thorax-abdominal CT scan between January 2016 and December 2019 were retrospectively reviewed (Material & Method shortened in abstract.). Oral contrast material wasn’t given to the patients. (Added) 210 patients with hiatal hernias, 126 (60%) were female and 84 (40%) were male. Among these patients, 124 (59 %) had type 1, 76 (36 %) had type 2, nine (4.2 %) had type 3, and one (0.4 %) had type 4 hiatal hernia. The most common complaints were cough (64%) and mild shortness of breath (34%). The most common clinical signs seen in the majority of patients were weight loss (73%) and loss of appetite (41%). All of the cases were mainly diagnosed based on radiological (CT) findings. With the increase in the use of CT for thoracic and abdominal diseases, there has been an increase in the frequency of incidental detection of hiatal hernias. Hernia diagnosis is important for preoperative surgical planning. Radiologists should be aware that complications of hiatal hernia can cause morbidity and mortality. The best diagnosis method is considered as CT, which is also useful in determining the type of hiatal hernias. © 2022, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Radiological Findings of Hepatic Epithelioid Hemangioendothelioma: A Rare Case Report
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Dündar, İ.; Özgökçe, M.; Durmaz, F.; Ayyıldız, V.A.; Özkaçmaz, S.
Hepatic epithelioid hemangioendothelioma is a rare, low-grade, vascular neoplasm with an unpredictable clinical course and usually misdiagnosed as other hepatic tumors based on radiological characteristic features. The most common organs involved are liver, lung and bone. It is still difficult to identify the tumor because it is usually asymptomatic and rare compared to other liver malignancies. Radiological imaging modalities may play an important role in the early diagnosis of this rare disease. In this report, our aim is to present imaging findings of hepatic epithelioid hemangioendothelioma with possible lung metastases in order to extend differential diagnosis and make accurate diagnosis. We evaluated a 38-year-old female patient with right upper quadrant pain using computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET-CT) imaging modalities. The definitive diagnosis was made after histopathological evaluation of biopsy. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Radiological Imaging Findings of Avalanche Victims With Traumatic Lesions in Van Eastern Province of Turkey
(Yuzuncu Yil Universitesi Tip Fakultesi, 2021) Özkaçmaz, S.; Dündar, İ.; Çoban, L.T.; İlik, İ.; Durmaz, F.; Çallı, İ.
This study aimed to present the radiological findings of survivors from two avalanches within two days in the same valley. This retrospective descriptive study was carried out in two centers after ethics committee approval. The radiological and demographical findings of 47 survivors were screened from two hospital databases. Patients were classified regarding the type of traumatic lesion as well as the lesion sites. A total of 39 traumatic lesions in 22 patients were detected via radiological imaging modalities. The female/male ratio was 4.8% (1/21) and the mean age was 42.6±17.1 years (24-86 years). Among the 39 traumatic lesions, 13 (33.3%) were detected in the extremities (4 in the muscles/ligaments, 9 in the bones), 9 (23.1%) in the spine (5 transverse, 2 spinous process, and 2 corpus fractures), 9 (23.1%) in the thorax (5 pulmonary contusion, 1 pneumomediastinum, 1 hemothorax, and 2 rib fractures), and 8 (20.5%) in the head (1 subdural hematoma, 5 maxillofacial fractures, and 2 subcutaneous hematomas). There were no abdominal or pelvic lesions detected in this study. Traumatic lesions can be seen in all systems and organs. Results of this study revealed that spinal and extremity fractures and pulmonary contusions were the most commonly reported traumatic lesions in the included av alanche victims. Muscular injuries were also detected. The use of MRI increases the success of lesion detection in intracranial structures and muscular-ligamentous tissues. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.

(Tabriz University of Medical Sciences, 2024) Koca, H.; Özgökçe, M.; Akinci, M.B.; Durmaz, F.; Ayyildiz, V.A.; Özkaçmaz, S.; Göya, C.
Introduction: The vast majority of lung masses are malignant. Benign lung masses include granulomatous inflammation and pneumonia consolidations. Malignant lung masses include lung cancers, lymphoma, and thymic neoplasms. Differentiating benign-malignant lung masses and treatment planning are essential for the prognosis of patients. Computed tomography (CT) guided transthoracic lung biopsy is a reliable diagnostic method with high accuracy and relatively few complications when an appropriate trace is selected. In this study, we aimed to present our experience and the results of lung mass cases that we biopsied with the guidance of CT. Methods: A total of 57 patients who were referred to us for clinicoradiological transthoracic biopsy (TTB) were studied with CT-guided histopathological sampling. The study did not include patients with no pathology results and ultrasound-guided biopsy. Results: A total of 57 patients, 42 male (73.6%) and 15 female (26.4%) with a mean age of 59.05 ± 17.04 (1-85), were evaluated. Thirteen of the lesions were reported as benign (22.8%), and 44 as malignant (77.2%). Conclusion: When an appropriate trace is selected, CT-guided transthoracic lung biopsy is a reliable diagnostic method with high accuracy and relatively few complications. © 2024 The Author(s).
