ABSTRACT
Exact localization of the bifurcation of the common carotid artery using skin surface landmarks is important for various diagnostic and therapeutic purposes, including emergency cases. Traditional methods have confirmed their accuracy in only a certain percentage of cases and there are inconsistencies among various publications. The cervical computed tomography-angiographic examinations for any diagnostic purpose between June 2017 and December, 2017 in the authors' hospital were examined. Measurements were performed for (MT-CB) and (MT-SE) distances and the results were recorded [MTâ=âThe tip of the mastoid process; CBâ=âcommon carotid artery bifurcation; SEâ=âsternal extremity of the clavicle]. Cervical computed tomography angiography was found in the records of 91 patients in the 6-month period between June 2017 and December 2017. After exclusion criteria were applied, a total of 116 carotid bifurcation levels on the right and left sides were measured in 58 patients. The mean MT-CB distance was 6.29â±â0.9âcm (range: 2.9-8.4âcm). The mean distance between MT and SE was 15.3â±â1.7âcm (range: 9.9-19.0âcm). The (MT-CB): (MT-SE) ratios ranged from 29% to 51% with a mean of 41â±â4.2% (95% CI: 39.88%-42.10%) and a median of 41.1% (Pâ<â0.05) (Kolmogorov-Smirnov test). The distance ratio values did not change significantly according to age and gender (respectively Pâ=â0.341, Pâ=â0.093). These results show that the CB is usually located at two-fifths of the distance from the mastoid tip to the sternal extremity of the clavicle and closer to the mastoid tip.

BACKGROUND: Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux. A new technique for venous insufficiency is non-thermal ablation with vein sealing system which comprises the endovenous delivery of cyanoacrylate tissue adhesive to the vein causing fibrosis. METHODS: This is a single-center prospective study of treatment of great saphenous vein incompetence in 62 patients with vein sealing system (Biolas VariClose® FG Group, Turkey). All cases were implemented under local anesthesia. Tumescent anesthesia was not required. Patients were not given any nonsteroidal anti-inflammatory drug postoperatively; advised to wear elastic bandages for 1 day; and compression stockings were not offered. RESULTS: Treatment success was defined as complete occlusion of treated vein or recanalized segment shorter than 5 cm. Subtotal recanalization was defined as great saphenous vein flow containing 5-10 cm segment of treated vein. A recanalized great saphenous vein or treatment failure was defined as an open part of the treated vein segment more than 10 cm in length. At 1 week and 1 month control, duplex scans showed total occlusion for all patients (100%), total occlusion for 58 patients (93.5%), and subtotal occlusion for 4 patients (6.5%) at third month. At the end of 6 months, total occlusion 56 patients (90.3%) and subtotal occlusion for 2 patients (3.2%). For 4 (6.5%) patients, no occlusion was observed, and the diameter was >11 mm. Embolization of great saphenous vein with cyanoacrylate has been performed since the beginning of this decade. Combined chemical and physical mechanism of action results in permanent vein closure. In a recently published study, a 24-month occlusion rate of 92% was demonstrated. The most commonly reported complications of cyanoacrylate use for the treatment of varicose vein disease, so far, include ecchymosis and phlebitis. Almeida et al. reported that phlebitis is the most frequent side effect at a rate of 16%. In our study, phlebitis rate was not as high as reported. It may be caused due to shorter time of follow-up in the hospital. CONCLUSION: Endovenous ablation of incompetent great saphenous vein with cyanoacrylate-based glue is feasible. Operation time is short, and tumescent anesthesia is unnecessary as postprocedure compression stockings. Lack of significant side effects and an yearly success rate of 100% are benefits of the system.

BACKGROUND: Juxta-anastomotic stenosis is a common issue of arteriovenous fistulas. We aimed to evaluate the results of percutaneous transluminal angioplasty with drug-coated balloon versus plain balloon for the treatment of juxta-anastomotic stenoses of mature but failing distal radiocephalic arteriovenous fistulas. METHODS: A total of 80 patients with a juxta-anastomotic stenosis of distal radiocephalic arteriovenous fistula in our clinic between January 2016 and September 2017 were retrospectively analyzed. Patients were divided into two groups according to the type of treatment as drug-coated balloon - percutaneous transluminal angioplasty (n = 44) and plain balloon - percutaneous transluminal angioplasty (n = 43). Intra- and post-procedural data were recorded. Target lesion primary patency rate was evaluated at 6 and 12 months. Of all patients, 48 were females and 39 were males with a mean age of 56.3 ± 10.4 (range, 24-75) years. Both groups had mature fistulas, and the mean age of fistula was 11.3 ± 9.1 months in the drug-coated balloon - percutaneous transluminal angioplasty group and 10.3 ± 8.8 months in the plain balloon - percutaneous transluminal angioplasty group (p = 0.24). RESULTS: There was no significant difference in the target lesion stenosis rate and the median lesion length between the groups. Technical and clinical success were achieved in both groups. Target lesion primary patency was similar at 6 months between the two groups (93.1% vs 81.3%, respectively; p = 0.14) but significantly higher for the drug-coated balloon - percutaneous transluminal angioplasty group at 12 months (81.8% vs 51.1%, respectively; p = 0.01). CONCLUSION: Our study results suggest that the use of drug-coated balloon combined with percutaneous transluminal angioplasty is an effective treatment for juxta-anastomotic stenoses of mature but failing distal radiocephalic arteriovenous fistulas with significantly improved target lesion primary patency rates and reduced need for juxta-anastomotic reinterventions.

OBJECTIVE: Data comparing radiofrequency ablation (RFA) with cyanoacrylate closure (CAC) treatment of isolated great saphenous vein (GSV) insufficiency are limited. In this study, we present our early outcomes of RFA vs CAC for the treatment of GSV insufficiency. METHODS: Between March 2015 and February 2017, a total of 159 patients underwent CAC (n = 75) or RFA (n = 84) for treatment of GSV insufficiency by a single surgeon. Medical data of the patients were retrieved from the institutional database and retrospectively analyzed. All patients underwent lower extremity venous color duplex ultrasound examination. The Venous Clinical Severity Score and Aberdeen Varicose Vein Questionnaire were used. Total closure rates of the GSV with RFA or CAC were recorded at 1 month, 6 months, and 12 months. Procedure-related adverse events and quality of life of the patients were also evaluated. RESULTS: The mean age was 46.33 ± 14.40 years in the CAC group and 48.09 ± 13.25 years in the RFA group (P = .4). The mean treated saphenous vein diameter was 7 mm in the CAC group and 7.25 mm in the RFA group (P = .07). The length of treated venous segment was 30 cm in both the CAC and RFA groups (P = .66). The mean duration of operation was 25 minutes in the CAC group and 35 minutes in the RFA group (P < .001). The incidence of adverse events was higher in the RFA group (P < .05). At 1 month, 6 months, and 12 months of follow-up, there was no statistically significant difference in the total closure rates between the CAC and RFA groups. There was no significant difference in the Venous Clinical Severity Score and Aberdeen Varicose Vein Questionnaire score between the groups (P > .05). CONCLUSIONS: Our study results suggest that both RFA and CAC are effective in closure of the target GSV. Although the incidence of tumescent anesthesia-related and procedure-related complications is higher with the RFA technique, both techniques can be used safely with similar success rate and patient satisfaction.

INTRODUCTION: The aim of this study was to determine the outcomes of patients developing ischemic stroke after coronary artery bypass grafting (CABG). METHODS: From March 2012 to January 2017, 5380 consecutive patients undergoing elective coronary surgery were analyzed. Ninety-five patients who developed ischemic strokes after on-pump coronary surgery were included in the study, retrospectively. The cohort was divided into four subgroups [total anterior circulation infarction (TACI), partial anterior circulation infarction (PACI), posterior circulation infarction (POCI), and lacunar infarction (LACI)] according to the Oxfordshire Community Stroke Project (OCSP) classification. The primary endpoints were in-hospital mortality, total mortality, and survival analysis over an average of 30 months of follow-up. The secondary endpoints were the extent of disability and dependency according to modified Rankin Scale (mRS). RESULTS: The incidence of stroke was 1.76% (n=95). The median age was 62.03±10.06 years and 68 (71.6%) patients were male. The groups were as follows: TACI (n=17, 17.9%), PACI (n=47, 49.5%), POCI (n=20, 21.1%), and LACI (n=11, 11.6%). Twenty-eight (29.5%) patients died in hospital and 34 (35.8%) deaths occurred. The overall mortality rate of the TACI group was significantly higher than that of the LACI group (64.7% vs. 27.3%, P=0.041). The mean mRS score of the TACI group was significantly higher than that of the other groups (P=0.003). CONCLUSION: Patients in the TACI group had higher in-hospital and cumulative mortality rates and higher mRS scores. We believe that use of the OCSP classification and the mRS may render it possible to predict the outcomes of stroke after coronary surgery.
