Mortality Outcomes of Endovascular Treatment and Surgical Clipping in Patients with Cerebral Aneurysms: A Single-Center Study.

AIM: To compare endovascular and surgical treatment methods for cerebral aneurysms focusing on mortality. MATERIAL AND METHODS: The study included 187 patients who had undergone aneurysm treatment. The patients were divided into four groups according to their treatment modality and subarachnoid hemorrhage status: patients with endovascular treatment and bleeding aneurysms (EVG-b), patients with endovascular treatment and non-bleeding aneurysms (EVG-nb), patients with surgical clipping and bleeding aneurysms (SCG-b), and patients with surgical clipping and non-bleeding aneurysms (SCG-nb). The Hunt?Hess scores, Fisher grade, aneurysm morphology, and length of stay (LOS) were compared between groups. RESULTS: There was no significant difference in the mortality rate between EVG-b and SCG-b at the end of the first year (23.5% and 39.7%, respectively; p > 0.05). A significantly shorter LOS was observed in EVG-b than in SCG-b (11.5 days and 15 days, respectively; p=0.027). Fusiform aneurysms were associated with higher patient mortality, whereas saccular aneurysms were associated with a 1.9-fold higher survival (p=0.037; 95% confidence interval: 0.83?4.74). The rate of closure of non-bleeding aneurysms was 93.4%. Complete embolization was verified in all bleeding aneurysms. In EVG-nb, the morbidity rate was 5%, the mortality rate was 3%, and the mean LOS was 2.86 days. CONCLUSION: Both treatment methods showed similar mortality rates, but hospital stays were shorter after endovascular treatment.

The risk of malignancy according to Milan reporting system of salivary gland fine-needle aspiration with Becton Dickinson SurePath liquid-based processing.

BACKGROUND: Fine-needle aspiration cytology (FNAC) is a noninvasive, safe, cost-effective, diagnostic procedure for the evaluation of salivary gland lesions and the selection of patients for surgery. The aim of this study was to analyze the risk of malignancy (ROM) according to the Milan reporting system of salivary gland FNA specimens using a liquid-based cytology (LBC) technique. METHODS: The cytological diagnosis of 459 cases between 2014 and 2017 was revised according to the Milan reporting system. The FNAC results of 129 cases with a histological diagnosis were compared with respect to the final diagnosis. The ROM for each category calculated. RESULTS: The ROM was high in the indeterminate and malignant categories, while the ROM in the benign neoplasm category was low. Sensitivity and specificity analyzed in two different ways were 95.1% and 88.8%, 81%, and 77.7%, respectively. CONCLUSIONS: When salivary gland lesions are evaluated together with clinical and radiological data, the LBC technique can be applied to salivary gland specimens based on the high diagnostic sensitivity and specificity in liquid-based samples reported according to the Milan system.

Natural course of hepatic focal nodular hyperplasia from childhood to adulthood and review of the literature.

Focal nodular hyperplasia (FNH) is the second most common benign tumor of the liver and constitutes 4% of all primary hepatic tumors in pediatric population. Imaging characteristics of FNH in adults are well known, but those in children have rarely been reported. Here we describe the natural course of a giant hepatic FNH, which was followed up from childhood to adulthood for 12 years using computed tomography (CT) imaging and liver enzyme tests (LET). Differences in CT imaging characteristics were demonstrated. Changes were found in the FNH size in CT images and they were correlated with LET findings. The regression of FNH in our case was compared with the findings in the literature. Hepatic capsular retraction was observed in a benign focal liver lesion in the medical literature for the first time.

Evaluation of mean platelet volume and platelet distribution width in patients with asymptomatic intermediate carotid artery plaque.

BACKGROUND: Platelets play a significant role in the pathogenesis of atherosclerosis. In atherosclerotic plaques, the risk of plaque rupture is more crucial than the severity of the stenosis they cause. Non-calcified carotid artery plaques are more unstable than calcified plaques, and they are associated with a higher risk of rupture, thromboembolism, and consequently, stroke. AIM: The purpose of the present study is to compare calcified and non-calcified plaques that cause intermediate carotid artery stenosis, with respect to mean platelet volume (MPV) and platelet distribution width (PDW). METHODS: A total of 139 asymptomatic patients with 50-70% stenosis of the carotid artery were included in this study. Carotid Doppler ultrasound imaging and computed tomography angiography were performed to divide the carotid artery plaques into two groups as calcified and non-calcified. Patients included in the calcified (n = 73) and non-calcified (n = 66) plaque groups were compared with respect to MPV and PDW. RESULTS: Mean platelet volume was statistically significantly higher in the non-calcified plaque group compared to the cal-cified plaque group (MPV in non-calcified/calcified plaque groups [fL]: 10.0/9.0, respectively) (p < 0.01). PDW was not significantly different between the two groups (p = 0.09). Platelet count was statistically significantly higher in the calcified plaque group compared to the non-calcified plaque group (platelet count in calcified/non-calcified plaque groups [10³/mm³]: 250 ± 63/226 ± 56, respectively) (p = 0.019). Multivariate regression analysis showed that MPV was independently associ-ated with non-calcified carotid artery plaque (odds ratio 5.95, 95% confidence interval 2.63-13.45, p < 0.001). CONCLUSIONS: Mean platelet volume is increased in the presence of non-calcified carotid artery plaques that cause asymp-tomatic intermediate stenosis. Increased MPV can be used as a marker to predict the risk of rupture of the non-calcified carotid artery plaques.

Successful Treatment of Uterine Arteriovenous Malformation due to Uterine Trauma.

Uterine arteriovenous malformation (AVM) is defined as abnormal and nonfunctional connections between the uterine arteries and veins. Although the patients typically present with vaginal bleeding, some patients may experience life-threatening massive bleeding in some circumstances. The treatment of choice depends on the symptoms, age, desire for future fertility, and localization and size of the lesion; however, embolization of the uterine artery is the first choice in symptomatic AVM in patients at reproductive age with expectations of future fertility. We report a case of acquired AVM (after D/C) with an extensive lesion, which was successfully treated with bilateral uterine artery embolization (UAE).

Is Elevated Neutrophil-to-Lymphocyte Ratio a Predictor of Stroke in Patients with Intermediate Carotid Artery Stenosis?

OBJECTIVE: An increased neutrophil-to-lymphocyte ratio (NLR) is associated with poor clinical prognosis in patients with cardiovascular disease. In this study, we aimed to investigate if there was a correlation between NLR and the risk of stroke in patients with intermediate carotid artery stenosis. METHODS: A total of 254 patients with a 50%-70% stenosis in the carotid artery, 115 of whom were symptomatic and 139 of whom were asymptomatic, were included in the study. Patients with a history of ischemic cerebrovascular event with or without sequelae, transient ischemic attack, and amaurosis fugax in the last 1-6 months were included in the symptomatic group of the study. The symptomatic and asymptomatic groups were compared in terms of total neutrophil count, lymphocyte count, and NLR. RESULTS: The total white blood cell count (WBC), neutrophil count, and NLR were found to be higher and the lymphocyte count was found to be lower in the symptomatic patients than those in the asymptomatic patients (symptomatic/asymptomatic, respectively, WBC [10(3)/mm(3)]: 9.0/8.2, neutrophil count [10(3)/mm(3)]: 6.1/5.0, NLR: 3.08/2.2, lymphocyte count [10(3)/mm(3)]: 1.9/2.2) (P < .001). The cutoff value for NLR was found to be 2.6 or higher. In the multivariate regression analysis, an NLR value of 2.6 or higher was shown to be an independent variable for carotid artery stenosis to become symptomatic. CONCLUSIONS: NLR is increased in symptomatic intermediate carotid artery stenosis. An increased NLR value is an independent variable for carotid artery plaques to become symptomatic.

Hepatic cystic echinococcosis: percutaneous treatment as an outpatient procedure.

OBJECTIVE: To demonstrate utility and safety of the puncture aspiration injection and reaspiration (PAIR) technique for outpatients. METHODS: Percutaneous treatment with US guidance was applied to 33 patients for 44 cysts. Patients treated with the PAIR technique, were outpatients. PAIR and catheterization technique were evaluated for efficacy and safety of procedure and complication rates. RESULTS: Thirty-five of 44 cysts were treated with the PAIR and 9 of 44 were treated with the catheterization technique. The success rate of the cysts Gharbi type 1 (CE1) and type 2 (CE3a) treated with the PAIR technique was 100%. In the follow up of 9 cysts treated with the catheterization technique, 2 of them (22%) developed cyst infection and 1 (11%) developed a biliary fistula. CONCLUSIONS: The PAIR technique was found to be an effective and safe approach in order to treat Gharbi type 1 and type 2 cysts percutaneously for outpatients. It has a very low complication rate in comparison with the catheterization technique. So every effort should be made to finish the treatment with PAIR technique.

Endovenous laser ablation and concomitant foam sclerotherapy: experience in 504 patients.

PURPOSE: To investigate the value of endovenous laser ablation (ELA) and concomitant ultrasound-guided foam sclerotherapy (USGFS) in patients with chronic venous insufficiency. METHODS: During a 6-year period, concomitant USGFS of the varicose veins were performed in 504 out of 610 patients who underwent ELA for truncal or perforating vein insufficiency. In these 504 patients (944 legs; bilateral in 440 patients), the incompetent veins were greater saphenous vein in 615 legs, small saphenous vein in 118 veins, perforating veins in 42 legs, and a combination of these in 169 legs. In all patients, after ELA of the incompetent veins, USGFS was performed for the remaining varicosities with 1-3% polidocanol foam. Patients were followed up clinically and with color Doppler ultrasound at 1, 6, and 12 months. RESULTS: ELA was technically successful in all cases, although another venous puncture was necessary in 29 legs. Concomitant USGFS was also technically successful in all cases, but one to three additional sclerotherapy sessions were performed in 203 legs with persistent varicosities. During the follow-up, recanalization of the laser-ablated refluxing veins occurred in 16 legs (1.7%) and was treated with repeat ELA or USGFS. Major complications occurred in 1.4% of the treated legs and included skin necrosis and calf vein thrombosis. CONCLUSION: ELA and concomitant foam sclerotherapy is feasible and effective. The procedures are associated with a low complication rate and can be performed in both legs in the same session. Concomitant use of laser and foam may potentially decrease the recanalization rate of laser-ablated vessels.

Age-related changes in the incidence of pineal gland calcification in Turkey: A prospective multicenter CT study.

The goal of this cross-sectional observational study was to determine the incidence of pineal gland calcification (PGC), to investigate the interaction of PGC and aging, and to compare the incidence of PGC among the populations living in Turkey. In a prospective study the rate of PGC on CT scans of 1376 individuals in six referral centers from different regions of Turkey was investigated, with emphasis on effects of climatological parameters and aging on PGC. It was found that the incidence of PGC increased rapidly after first decade and the increase remains gradual thereafter, higher in males than in females for all age groups. There was a significant difference for incidence and degree of PGC between different clinics and between both sexes (p<0.001). In addition, there was a significant difference for the degree of PGC between the clinics in low altitude group and those in high altitude group (p<0.001 for each). Logistic regression analysis revealed that age, sex, altitude and intensity of sunlight exposure significantly affected the risk of PGC (odds ratios (OR) 1.335, 95% confidence intervals (CI) 1.261-1.414, p<0.001; OR 1.900, 95% CI 1.486-2.428, p<0.001; OR 0.715, 95% CI 0.517-0.990, p<0.05; OR 0.997, 95% CI 0.994-0.999, p<0.01, respectively). Furthermore, by multiple linear regression analysis, high altitude and increased intensity of sunlight exposure were found to affect the degree of PGC (beta=0.003, p<0.001). It is concluded that there is a close relationship between PGC and the aforementioned parameters, supporting a link between the development of PGC and these. This study provides some reference data for new clinical studies on the putative role of pineal gland in future.

Endovenous laser ablation for saphenous vein insufficiency: immediate and short-term results of our first 60 procedures.

PURPOSE: To present the immediate and short-term results of our first 60 endovenous laser (EVL) ablation procedures. MATERIALS AND METHODS: Between July 2005 and December 2006, 60 EVL ablations were performed in 36 symptomatic patients (26 females, 10 males; mean age +/- SD, 46 +/- 14 years). The incompetent veins included the great saphenous vein (GSV) (n = 52), small saphenous vein (n = 6), and major branches of the GSV (n = 2). In all cases incompetent veins were punctured under ultrasound (US) guidance and the laser fiber was placed into these veins through a vascular sheath or with the help of a catheter. After tumescent anesthesia was administered, the veins were ablated with laser by delivering 50-100 joules/cm energy to the vein wall. Following EVL ablations, 29 patients also underwent foam sclerotherapy to treat the remaining varicosities. After the EVL ablation +/- sclerotherapy, patients were followed- up with Doppler US at 1 week, and then 3, 6, and 12 months post procedure. RESULTS: In all patients EVL ablation was technically successful. Complications were minor and included transient visual disturbance due to foam sclerotherapy (n = 1), bruising/ ecchymoses (n = 24), postoperative pain (n = 16), and superficial thrombophlebitis (n = 6). All patients returned to normal activity within 2 days. During the 7 +/- 5 months (mean +/- SD) of follow-up, recurrent reflux was seen in only one patient, in both GSVs, which was successfully treated with foam sclerotherapy. CONCLUSION: EVL ablation is a safe and effective method for the management of saphenous vein insufficiency.
