    Left-Sided Atrial Septal Pouch and Risk of Cryptogenic Stroke
    (2016) Yilmaz, Murat; Vural, Mustafa Gokhan; Karcaaltincaba, Musturay; Yoldas, Tahir Kurtulus; Yilmaz, Muhittin Serkan; Kavalci, Cemil; https://orcid.org/0000-0003-2529-2946; AGG-1308-2022
    Introduction: Stroke is the second most cause of death worldwide after coronary artery disease. Left-sided atrial septal pouch (LASP) is associated with potential cardioembolic stroke. This study determines the association between LASP and cryptogenic stroke (CS) using cardiac multi-detector computed tomography (cMDCT) angiograms. Materials and methods: This study included 40 patients with CS (23 males, mean age: 403 +/- 10.4 years) and 40 age- and sex matched healthy controls. cMDCT examinations by dual-source 64-slice MDCT with 0.6-mm slice thickness were performed for all patients and controls. The association between LASP and risk of CS was assessed after adjustment for other stroke risk factors. Results: Patients with LASP were younger than control subjects (41.3 +/- 7.2 years vs 44.2 +/- 5.7 years; p = 0.066), with a comparable prevalence of hypertension (42.5% vs 35%; p = 0.491) and other risk factors. There were no differences in the prevalence of LASP between patients and controls (32.5% vs 25%; p = 0.621). LASP was observed in 43.5% (n = 10) of normotensive stroke patients compared to 15.4% (n = 4) of normotensive controls (Odds Ratio (OR): 4.23, 95% CI: 1.09-16.27, p = 0.063). On the other hand, LASP was detected in 17.6% (n = 3) of hypertensive CS patients compared to 42.9% (n = 6) of hypertensive controls (OR: 028, 95% CI: 0.05-4.23, p = 0.253). The presence of LASP was not associated with an increased risk of CS. Conclusion: This study suggests that LASP is associated with CS. However, in normotensive individuals, LASP may be a minor risk factor for CS.

    Pathology associated with adherent perirenal fat and its clinical effect
    (2021) Ceyhan, Erman; Ileri, Fatih; Aki, Fazil Tuncay; Yazici, Mustafa Sertac; Karcaaltincaba, Musturay; Ertoy Baydar, Dilek; Bilen, Cenk Yucel; 0000-0001-8223-6399; 34120392; ABI-2513-2020
    Introduction The dissection of perirenal fat is of critical importance to kidney surgery and ease of dissection is more important when using minimally invasive approaches. This study aimed to determine the clinical, radiological, and pathological significance of adherent perirenal fat (APF). Materials and Methods This prospective study included 22 patients scheduled for partial nephrectomy and 40 patients for donor nephrectomy. Intraoperative fat dissection time was recorded, and the complexity of perirenal fat dissection was surgeon-classified as easy, moderate, and difficult. Perirenal fat and subcutaneous fat thickness were measured. Measurement of perirenal fat depth and the Hounsfield unit (HU) for both perirenal and subcutaneous fields were performed using computed tomography (CT) images. All specimens were submitted for histopatological analysis. Researchers in each arm were blinded to other researchers' data. Results Mean age of the patients was 51.3 +/- 12.7 years. Mean perirenal fat dissection time was 15.0 +/- 13.5 minutes. Patient demographics, BMI, nor occupational status differed between the 3 complexity of perirenal fat dissection groups. Radiological findings showed that there was a significant correlation between perirenal fat depth and complexity of perirenal fat dissection (P < .05), but not with HU measurements or subcutaneous fat thickness. Surgeon classification of the complexity of perirenal fat dissection was in accordance with the duration of dissection (P < .05). Perinephric fat contained more fibrous tissue in the patients with histologically proven APF than in those without (P < .05). Conclusions APF is a challenge during kidney surgery. Difficult dissection prolongs the duration of perirenal fat dissection and surgery. Perirenal fat thickness measured via preoperative CT might be used to predict APF.
