RESUMEN
BACKGROUND AND STUDY AIM: We present the use of the magnetic compression anastomosis (MCA) technique for treatment of disconnected bile duct after living-donor related liver transplantation (LDLT) using the recently introduced through-the-scope magnet. PATIENTS AND METHODS: The MCA technique was used in patients with disconnected bile duct who could not be treated with either percutaneous or endoscopic procedures. All patients already had a percutaneous external biliary drainage catheter before the procedure. The magnet was placed percutaneously into the proximal side of the obstruction by pushing a 5-Fr catheter over a guidewire. Concurrently, endoscopic retrograde cholangiopancreatography (ERCP) including endoscopic papillary sphincterotomy was performed. The sister magnet was then carefully advanced to the opposite side of the obstruction with a 5-Fr catheter over a guidewire. After the confirmation of biliary recanalization, a guidewire was passed through the stricture and a percutaneous dilation of the stricture was performed with a balloon-tipped catheter. Endoscopic balloon dilation of the stricture, insertion of two plastic stents and the removal of the internal drainage catheter were performed during the first ERCP session. Stent exchange and multiple side-by-side stent placements were planned at regular intervals (3 monthly) for all patients. RESULTS: A total of six LDLT patients with disconnected bile duct (aged 37â-â68, four men) underwent the MCA technique between September 2014 and July 2015. Biliary recanalization was achieved 13â-â42 days after the magnet placement procedure. The success rate of the procedure was 100â%. CONCLUSIONS: The MCA technique using a small magnet (diameter 2.4âmm) is effective and useful in LDLT patients with disconnected bile duct.

INTRODUCTION: Intracranial infectious aneurysm (IIA) accounts for less than 5% of all intracranial aneurysms. The aim of this study was to evaluate the role of endovascular treatment for IIA. METHODS: During a 14-year period, 15 patients (age range, 2-68 years; mean, 42.8 years) with 17 aneurysms were diagnosed with IIA and treated via an endovascular route at our institution. The IIA diagnosis was based on clinical and laboratory findings of infection, echocardiography results, and digital subtraction angiography that were collected retrospectively. All patients were clinically and radiologically followed. The modified Rankin scale was used to evaluate clinical outcome. RESULTS: Among 15 patients, 12 presented with ruptured aneurysms (7 intraparenchymal hematoma, 4 subarachnoid hemorrhage, 1 subdural hematoma), 2 with cerebral infarcts, and 1 with pansinusitis and epidural abscess. All but one aneurysm were distally located in intracranial circulation, 14 were in anterior, and the remaining 3 were in posterior circulation. The final diagnosis was based on aneurysm morphology, location, and clinical laboratory findings. Endovascular treatment was scheduled initially for all IIAs; 13 of 17 IIAs underwent endovascular parent vessel occlusion, 3 underwent spontaneous parent vessel occlusion while waiting for intervention, and the remaining patient was treated by intrasaccular coil occlusion. There were no instances of perioperative neurological complications. Late clinical and radiological outcomes included absence of endovascular treatment related to mortality and aneurysm recurrence. CONCLUSION: Endovascular treatment may be performed safely at the time of diagnosis for at least symptomatic IIAs under the protective effect of antibiotic treatment.

Intramuscular hemangiomas are benign neoplasms usually seen in children and adolescents. They tend to occur in the deep fascia and muscle and more often in the lower extremity, although they are rarely encountered in the plantar musculature. Surgical excision, ultrasound- or fluoroscopic-guided percutaneous sclerotherapy, and angiographic embolization are all treatment options. Surgical excision is the most prevalent form of therapy, although this can be difficult in the hands and feet. For this reason, ultrasound- and fluoroscopic-guided percutaneous sclerotherapy is a useful treatment option for pedal intramuscular hemangioma. In the present report, we describe 2 cases of intramuscular hemangioma in children, 1 treated by excision and 1 by percutaneous sclerosis.

PURPOSE: To perform biochemical profiles before and after percutaneous transhepatic biliary drainage (PTBD) and investigate the potential utility of measuring C-reactive protein (CRP), circulating cytokines, and neopterin, a marker of cell-mediated immunity, to predict outcomes of patients with obstructive jaundice. MATERIALS AND METHODS: In a prospective study, 47 patients with obstructive jaundice secondary to malignant lesions were evaluated before, at the fifth hour after, and on the fifth day after PTBD for neopterin, nitrate, tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, CRP levels, and liver function. RESULTS: Neopterin levels on day 5 after PTBD were significantly higher than the levels before treatment and at the fifth hour. However, nitrate, cytokine, white blood cell, albumin, and creatinine levels were not significantly different. On the fifth day after PTBD, CRP levels were significantly higher and total bilirubin, direct bilirubin, alkaline phosphatase, aspartate transaminase, and alanine transaminase values were lower than the before-treatment values. Seven patients (15%) died within 30 days after drainage. On the fifth day after PTBD, neopterin, IL-6, IL-10, and creatinine levels were significantly higher and albumin levels were lower in the early mortality group. The performance characteristics of neopterin and creatinine were statistically significant in predicting mortality. CONCLUSIONS: Neopterin levels increased after PTBD, indicating cellular immune activation. The nonsignificant change in cytokine levels may be related to low enduring release in malignancy. The extremely elevated levels of neopterin and creatinine after PTBD might serve as harbingers of early death in patients with cholestasis secondary to malignant lesions.

INTRODUCTION: The current literature describing surgical and endovascular interventions in blister-like aneurysms (BAs) offers no clear consensus on the optimal treatment modality. The aim of this study was to assess the clinical and angiographic features of ruptured BAs treated endovascularly using predominantly flow-diversion strategy. METHODS: The initial clinical and radiological findings, endovascular treatment results, clinical outcomes, and follow-up angiographic findings of seven BAs (one man and six women; mean age, 44.5 years; range, 33-50 years) were retrospectively evaluated. RESULTS: All seven BAs were located in the supraclinoid internal carotid artery. Two patients were managed initially by other endovascular treatment options, after that flow-diverting strategy became intention to treat in these two and the remaining five patients. Flow-diverting treatment with pipeline stent (Covidien/Ev3) could be accomplished in all but one patient who was treated by parent artery occlusion due to an access problem. Dual antiaggregant loading was performed 6-8 h before treatment in all patients. No re-bleeding or thrombotic complication occurred periprocedurally. Long-term control angiography was available in all patients revealing occluded aneurysm. The clinical outcome (mRS) was good in five and moderate in two patients. CONCLUSIONS: Endovascular reconstructive treatment of a ruptured BA using a flow-diverting device is a promising strategy that can be performed with acceptable clinical and good radiological results.

The combination of a solitary pelvic kidney and an abdominal aortic aneurysm is extremely rare. We demonstrate a chimney graft implant in a patient with a solitary pelvic kidney. A 63-year-old man was diagnosed with an abdominal aortic aneurysm found incidentally. Preoperative computed tomography illustrated a fusiform abdominal aortic aneurysm accompanying a solitary ectopic kidney in the pelvis with an aberrant renal artery. A bifurcated endograft was implanted, and a covered stent graft was placed into the renal artery using the chimney technique. Good patency of the chimney graft was documented with early postoperative and first month scans. To the best of our knowledge, this is the first report of the chimney technique used for a solitary pelvic kidney.

PURPOSE: To assess the treatment response of hepatocellular carcinoma (HCC) after transarterial chemoembolization with diffusion-weighted imaging and dynamic contrast-enhanced magnetic resonance (MR) imaging with a 3-T system. MATERIALS AND METHODS: Between February 2010 and November 2010, 74 patients were treated with chemoembolization in our interventional radiology unit. Twenty-two patients (29%) who had liver MR imaging including diffusion and dynamic contrast-enhanced MR imaging on a 3-T system before and after transarterial chemoembolization were evaluated retrospectively. Tumor size, arterial enhancement, venous washout, and apparent diffusion coefficient (ADC) values of lesions, peritumoral parenchyma, normal liver parenchyma, and spleen were recorded before and after treatment. The significance of differences between ADC values of responding and nonresponding lesions was calculated. RESULTS: The study included 77 HCC lesions (mean diameter, 31.4 mm) in 20 patients. There was no significant reduction in mean tumor diameter after treatment. Reduction in tumor enhancement in the arterial phase was statistically significant (P = .01). Tumor ADC value increased from 1.10 × 10(-3) mm(2)/s to 1.27 × 10(-3) mm(2)/s after treatment (P < .01), whereas the ADC values for liver and spleen remained unchanged. ADC values from cellular parts of the tumor and necrotic areas also increased after treatment. However, pretreatment ADC values were not reliable to identify responding lesions according to the results of receiver operating characteristic analysis. CONCLUSIONS: After transarterial chemoembolization, responding HCC lesions exhibited decreases in arterial enhancement and increases in ADC values in cellular and necrotic areas. Pretreatment ADC values were not predictive of response to chemoembolization.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a frequently performed operation. Leaks are formidable complications; however, the optimal management of these leaks is controversial. METHODS: We retrospectively reviewed the medical records of 15 patients referred to our tertiary center between 2012 and 2016 with leaks after LSG. RESULTS: In 12 patients with whom ongoing leaks were identified, stents were inserted with the intent of definitive therapy. In addition to attempts at source control, percutaneous drainage was carried out for intraabdominal collection in 9 patients and pleural effusion in 4 patients. The length of stay in the intensive care unit was significantly shorter in patients referred earlier or in those without any intervention. CONCLUSION: LSG leaks can be treated nonoperatively in well-organized centers under meticulously designed protocols, depending on the clinical condition of the patient.

The use of serological tests containing multiple immunodominant antigens rather than single antigens have the potential to improve the diagnostic performance in Cystic Echinococcoses (CE) as a complement tool to clear the inconclusive imaging data. Here, we comparatively evaluated the diagnostic value of Hydatid Fluid (HF) and the recently described recombinant multi-epitope antigen DIPOL in IgG-ELISA in a clinically defined cohort of CE patients. The serum samples from 149 CE patients were collected just before surgical or Percutaneous- Aspiration- Injection- Reaspiration (PAIR) procedures. Additionally, serum samples of patients with other parasitic infections (n=49) and healthy individuals (n=21) were also included in the study as controls. To investigate the association between the genotype of the parasite and DIPOL, cyst materials from 20 CE patients were sequenced. In terms of overall sensitivity, HF was higher than DIPOL (82.55%,78.52%, respectively). However, while the sensitivity of HF was higher than DIPOL in patients with active and transitional cysts (83.3%, 75.4%, respectively), sensitivity of DIPOL in inactive cysts was higher compared to HF (95.6%, 78.3%, respectively). The sensitivity of DIPOL depending on cyst stage was statistically significant (P= 0.041). In terms of specificity, DIPOL was found to be better than HF (97.71%, 91.43%, respectively). By genotyping, the majority of 20 patients showed G1 genotype (80%). All patients harboring G3 and G1/G3 cyst genotypes were positive with both antigens, while 87.5% of patients with G1 genotype were seropositive with HF and 75% with DIPOL. The overall sensitivity and high specificity of DIPOL suggest that this recombinant protein containing immunodominant epitopes is a potential substitute for the HF by serological tests for the diagnosis of CE.

Objective: The follow-up of patients with cystic echinococcosis (CE) offers the opportunity of evaluating the prognosis of the infection as well as detecting relapse. This study aimed to evaluate the performance of the new multiepitope recombinant peptide (recDipol) antigen in the follow-up of CE patients treated by surgery or percutaneous aspiration injection respiration. Methods: A total of 137 blood samples from 28 patients were evaluated by IgG-ELISA method using recDipol and hydatid fluid (HF) antigens. The patients were simultaneously checked for recurrence by ultrasonography. Results: The seropositivity rate of the 28 patients varied considerably during the follow-up. When the first blood of the patients was evaluated, 4 (14.28%) were seronegative by HF-ELISA and 9 (32.14%) were recDipol-ELISA. During the entire follow-up, only 1 (3.5%) and 6 (21.4%) patients were seronegative by HF-ELISA and recDipol ELISA, respectively. Conclusion: We found that recDipol did not perform as expected in the follow-up due to the higher number of seronegative patients compared to HF-ELISA in the first blood and during the entire follow-up. Our results suggest that imaging methods are gold standards in the diagnosis and that, in parallel, longer-term patient follow-up is required with recombinant antigens that have an improved diagnostic performance.

A 13-year-old boy who underwent thoracoabdominal aortic bypass when he was three years old for middle aortic syndrome was admitted with fatigue and need for an increased dose of antihypertensive mediations. The graft was patent, but there were stenoses at the juxta-proximal and juxta-distal anastomosis sites. A partial benefit was gained with endovascular stenting. Although postponement of surgery, until the child reaches full growth is preferred, surgery remains the inevitable treatment of choice in patients with middle aortic syndrome. In contrary, it is important to use the graft as large as possible during the initial operation to avoid patient-graft mismatch in the future.
RESUMEN
AIM: Eagle syndrome is a rare entity that causes recurrent throat pain, neck pain, dysphagia, or facial pain due to an elongated styloid process or calcified stylohyoid ligament. Clinical findings related to lower cranial nerve compression have also been reported. In some cases, it is reported that carotid artery compression or dissection can be seen due to elongated styloid process and this is called carotid artery syndrome. Carotid artery compression causes flow reduction and carotidynia or neurological symptoms can be seen. Dural sinuses and the jugular vein can be compressed. Eagle syndrome with neurological symptoms has been rarely reported. MATERIAL AND METHODS: The data of 5 patients (aged between 22 and 68 years), who presented to the hospital with various neurological symptoms, were retrospectively reviewed. Each patient underwent computed tomography (CT) that revealed a long styloid process. RESULTS: An elongated styloid process caused neurological symptoms. Two patients had venous compression by the styloid process and the other patients had transient ischemic attacks due to internal carotid artery compression by the styloid process. Only one patient underwent surgical removal. All patients" outcomes were good after treatment and no symptoms remained. CONCLUSION: Eagle syndrome may be presented with neurological symptoms. It should be kept in mind in the differential diagnosis of patients who have neurological symptoms without any objective etiological factors. To the best of our knowledge, Eagle syndrome with arterial and venous compression due to elongated styloid process has not been previously presented in the literature.

OBJECTIVE: Iatrogenic bile duct injuries remain a challenge for the surgeons to overcome. The predictive factors affecting morbidity and mortality are important for determining the best management modality. MATERIAL AND METHODS: The patients who referred to Ege University Faculty of Medicine after laparoscopy associated iatrogenic bile duct injury are grouped according to Strasberg-Bismuth classification system. The type and number of prior attempts, concomitant complications, and treatment modalities are analyzed using the SPSS version 18 (IBM, Chicago, IL, USA). The variables with p<0.10 were considered for univariate analysis and then evaluated for predictive factors by forward Logistic Regression method using multiple logistic regression analysis. RESULTS: According to the analysis of 105 patients who were referred during 2004-2014, the type and number of prior attempts are considered predictive factors in sepsis. In multiple logistic regression analysis, abscess formation, concomitant vascular injury, and serum bilirubin level are significantly effective in predicting mortality. CONCLUSION: The management of iatrogenic bile duct injuries should be carefully planned with a multidisciplinary approach. The predictive factors affecting morbidity and mortality are important in determining the best modality for managing iatrogenic bile duct injuries. Abscess formation, vascular injury, and serum bilirubin level are the potential risk factors. Therefore, we can strongly recommend immediate assessment of patients for prompt diagnosis and referring to an HPB center, to avoid further injuries.
RESUMEN
PURPOSE: The snorkel technique is commonly used to preserve renal arteries in juxta renal aneurysm during endovascular repair. Herein, we present a patient who underwent bifurcated endograft implantation with snorkel technique for inferior mesenteric artery (IMA) in order to preserve the major source of bowel circulation. CASE REPORT: A 69-year-old male patient was diagnosed with abdominal aortic aneurysm. His history revealed that he had bowel resection due to a car accident 30 years ago. In addition, he was given relaparotomy 4 times due to intestinal complications. Computed tomography showed fusiform aneurysm with a maximal diameter of 60 mm and chronical occlusion of the superior mesenteric artery. Inferior mesenteric artery was found to be hypertrophic. During EVAR, 6 mm × 10 cm covered VIABAHN Endoprosthesis (Gore Medical) was implanted to the IMA over a 0.018 guidewire via puncture of the left axillary artery. Initially, the main body of the aortic stent-graft (Gore C3, size 23-14-16) was implanted to the infra renal segment of the aorta (below the renal arteries and the orifice using VIABAHN) via the right femoral artery. Next, the contralateral leg (Gore, 14-12-00) was implanted. Computed tomography was examined at 1- and 32-month postoperatively, and no endoleak or patency of IMA stent was detected. CONCLUSION: In this case of IMA-dependent circulation of the intestinal system, the protection of IMA via snorkel technique was successful.

Chronic granulomatous disease (CGD) is a primary immune deficiency causing predisposition to infections with specific microorganisms, Aspergillus species and Staphylococcus aureus being the most common ones. A 16-year-old boy with a mutation in CYBB gene coding gp91phox protein (X-linked disease) developed a liver abscess due to Staphylococcus aureus. In addition to medical therapy, surgical treatment was necessary for the management of the disease. A 30-month-old girl with an autosomal recessive form of chronic granulomatous disease (CYBA gene mutation affecting p22phox protein) had invasive aspergillosis causing pericarditis, pulmonary abscess, and central nervous system involvement. The devastating course of disease regardless of the mutation emphasizes the importance of early diagnosis and intervention of hematopoietic stem cell transplantation as soon as possible in children with CGD.
RESUMEN
BACKGROUND AND PURPOSE: Pretreatment with dual antiaggregant drugs is accepted as a standard step in intracranial stent implantation. The aim of this study was to determine whether tailored antiaggregant medication based on platelet reactivity testing with multiple electrode aggregometry (Multiplate) yields superior outcomes after intracranial flow-diverting stent (FDS) implantation compared with standard clopidogrel treatment. METHODS: We retrospectively analyzed the following data from 100 consecutive patients: endovascular procedure characteristics, antiaggregant medications, procedural variables, and perioperative complications after FDS implantation for intracranial aneurysm. Patients were divided into two groups: uniform treatment with clopidogrel (untailored, early phase) and tailored treatment based on the results of aggregometry (late phase). Statistical comparisons included the Fisher exact test to compare categorical variables between the standard and aggregometry groups and the Mann-Whitney U test to compare ADP test values within the aggregometry group between groups receiving tailored or untailored treatment. RESULTS: In the aggregometry group (68 patients, 71 procedures) there were 17 (25%) clopidogrel-resistant patients, according to a cut-off value of 468 area under the aggregation curve; 12 underwent FDS implantation under tailored antiaggregant medication. In the standard treatment group (32 patients, 33 procedures) there were 3 (9.1%) spontaneous thrombotic events and 1 (3.3%) technical hemorrhagic complication. In the aggregometry group there were 2 (2.8%) spontaneous hemorrhagic events and 1 (1.4%) technical ischemic complication. In the aggregometry group, thrombotic complications and morbidity were lower than in the standard (no test) group (p<0.03). CONCLUSIONS: Tailoring platelet reactivity according to multiple electrode aggregometry decreases the rate of thrombotic complications after intracranial FDS implantation.

Mandibular arteriovenous malformations (AVMs) are rare and potentially life-threatening vascular lesions. Surgery, embolization, or bone cement implantation is an option for the treatment of mandibular AVMs. We present a case of huge mandibular AVM refractory to multiple embolizations of the supplying arteries, which was treated with polymethylmethacrylate (PMMA) bone cement implantation after the extraction of a molar tooth.
RESUMEN
PURPOSE: May-Thurner syndrome (MTS) is a rare clinical entity featuring venous obstruction of the left lower extremity. The aim of the present study was to report our experience with MTS and to evaluate the utility of treatment using endovascular techniques. MATERIALS AND METHODS: We retrospectively analyzed data on 23 MTS patients (21 females, two males; mean age 44 ± 15 years). Eighteen patients presented with deep vein thrombosis (DVT) and five with symptoms associated with chronic venous hypertension (CVH). DVT patients were treated via thromboaspiration, catheter-directed thrombolysis, and angioplasty; followed by stent placement. CVH patients were treated with angioplasty and stent placement alone. All patients were followed-up using Doppler ultrasonography and computed tomography venography. RESULTS: Complete left common iliac vein patency was achieved in 21 of the 23 patients (technical success rate: 91,3%). Complete thrombolysis was attained by 14 of the 18 DVT patients (77.7%). The mean clinical and radiological follow-up time was 15.2 ± 16.1 months. Upon follow-up, complete symptomatic regression was observed in 19 of the 23 patients (82.6%). Stent patency was complete in 19 of the 21 patients (90.4%) who received stents. Restenosis occurred in two patients. No treatment-related mortality or morbidity was observed. CONCLUSION: Endovascular treatment of MTS is safe and effective and reduces symptoms in most patients, associated with high medium-term patency rates.
