Objective To evaluate the efficacy of different interventions to the extra cranial lesions in acute ischemic stroke (AIS) due to anterior tandem lesions (TL) on reperfusion. Methods As a multi-center, cross-sectional study, AIS due to anterior TL receiving mechanical thrombectomy (MT) were retrospectively collected. Interventions to the extra-cranial stenosis were recorded. Post-procedural reperfusion was assessed using the modified thrombolysis in cerebral infarction (mTICI) score. Complete revascularization was defined as mTICI 3 and good revascularization was defined as mTICI 2b/3. The relationship between different extra-cranial intervention regimens and rate of re-vascularization was compared. Results Totally 117 patients were included with 92.3% reaching good recanalization and 63.2% reaching complete re-canalization. There was no significant difference in good re-canalization rates among various extra-cranial intervention regimens. The rate of complete re-canalization was significantly higher in patients receiving endovascular therapy(P＜0.05) and there was significant difference among various endovascular treatment regimens(P＜0.01): acute balloon angioplasty only group presented the highest rate of complete re-canalization (100.0%), followed by acute stenting only group (80%), acute stenting + balloon angioplasty group (73.7%) and conservative treatment group (54.3%). Conclusions Endovascular intervention to extra-cranial stenosis contributes to complete re-canalization in AIS due to anterior TL receiving MT, and acute balloon angioplasty seems to be quite effective than acute stenting.

Abstract Background Fibrosing mediastinitis (FM) is a rare yet fatal condition, caused by different triggers and frequently culminating in the obstruction of the pulmonary vasculature and airways, often leading to pulmonary hypertension and right heart failure. Percutaneous transluminal pulmonary venoplasty (PTPV) is an emerging treatment for pulmonary vein stenosis (PVS) caused by FM. Our previous study showed as high as 24% of in-stent restenosis (ISR) in FM. However, the predictors of ISR are elusive. Objectives We sought to identify the predictors of ISR in patients with PVS caused by extraluminal compression due to FM. Methods We retrospectively enrolled patients with PVS-FM who underwent PTPV between July 1, 2018, and December 31, 2022. According to ISR status, patients were divided into two groups: the ISR group and the non-ISR group. Baseline characteristics (demographics and lesions) and procedure-related information were abstracted from patient records and analyzed. Univariate and multivariate analyses were performed to determine the predictors of ISR. Results A total of 142 stents were implanted in 134 PVs of 65 patients with PVS-FM. Over a median follow-up of 6.6 (3.4–15.7) months, 61 of 134 PVs suffered from ISR. Multivariate analysis demonstrated a significantly lower risk of ISR in PVs with a larger reference vessel diameter (RVD) (odds ratio (OR): 0.79; 95% confidence interval [CI]: 0.64 to 0.98; P = 0.032), and stenosis of the corresponding pulmonary artery (Cor-PA) independently increased the risk of restenosis (OR: 3.41; 95% CI: 1.31 to 8.86; P = 0.012). The cumulative ISR was 6.3%, 21.4%, and 39.2% at the 3-, 6-, and 12-month follow-up, respectively. Conclusion ISR is very high in PVS-FM, which is independently associated with RVD and Cor-PA stenosis. Trail Registration Chinese Clinical Trials Register; No.: ChiCTR2000033153.

Objective To explore the effect of age factor on the success rate of lacrimal probing in the congenital nasolacrimal duct obstruction (CNLDO). Methods This report was based on a single-center retrospective case series study. The gradient therapeutic regimen was adopted, and lacrimal probing was undertaken to treat CNLDO when conservative treatment was ineffective. The patients were categorized into 4 groups by age: 0-＜6 months,6-＜12 months,12-＜24 months and 24-60 months. The success rate of probing in each group was compared and the correlation with age was analyzed. Results A total of 314 eyes of 269 patients were included. The success rates of primary probing in 4 groups were 86.8%, 91.7%, 73.6% and 37.8%, respectively. The overall success rate of probing in all patients was 84.7%(266/314). The decreased success rate of probing at age beyond 12 months was significantly correlated with increasing age(P＜0.001). No significant correlation was found with sex or laterality. Conclusions Staged treatment strategy is safe and effective. The success rate of probing is negatively correlated with age. Initial probing is recommended in children under 2 with failure of the conservative management.

Tracheal stenosis due to invasion of thyroid malignancy is a rare entity. Management of the airway in such a patient is a critical step in palliative care. We discuss the successful management of tracheal stenosis due to anaplastic transformation of papillary thyroid carcinoma in an 84-year-old female. There are several methods for airway management in tracheal stenosis. Self-expanding stent placement is a less invasive, efficient procedure for tracheal stenosis.

Key Clinical Message Early recognition and diagnosis of subclavian steal syndrome are vital to avoid unnecessary investigations and ensure appropriate management. This case highlights the significance of comprehensive evaluation, including bilateral blood pressure measurement, in patients with unilateral symptoms.

Vascular inflammation has a pivotal role in the progression of atherosclerosis and major cardiovascular events (MACE). However, there is limited data concerning to role of changes in inflammatory markers in predicting MACE. In the current study, it was investigated whether the difference between high sensitive C-Reactive Protein (hs-CRP) and systemic immune-inflammatory index values (Δhs CRP and ΔSII) measured before and after the procedure and residual SYNTAX score (rSS) in stable coronary artery patients underwent percutaneous coronary intervention (PCI) could predict MACE. 203 patients (mean age: 62.11±9.20, 75% male) were included in the study. Before the first procedure and at the 1st month after the procedure(s), their blood was drawn. rSS was calculated. MACE was determined as cardiovascular mortality, target vessel revascularization non-fatal myocardial infarction, and ischemic stroke. MACE was observed in 20 patients (9.9%). Of these patients, 3 (1.5%) had cardiovascular mortality, 3 (1.5%) had a non-fatal myocardial infarction, 12 (5.9%) had target vessel revascularization due to unstable angina, and the remaining 2 (1.0%) had an ischemic stroke. The area under the curve (AUC) to predict MACE diagnosis was 0.548 for ΔSII and 0.647 for Δhs-CRP and 0.766 for rSS. In multiple regression analysis, only rSS > 4 was an independent predictor for MACE (HR=3.41, 95% CI: 1.39-8.35, p=0.007). The change in SII and hs-CRP after PCI was found to be insufficient to predict MACE, while rSS was the only independent predictor for MACE. [Med-Science 2023; 12(2.000): 536-41]

Budd-Chiari syndrome (BCS) is a rare condition characterized by hepatic venous outflow obstruction. Balloon angioplasty, with or without stenting, is the recommended first-line treatment modality in Asian countries. As a supplement to balloon angioplasty, expandable metallic Z-stent deployment can effectively improve long-term inferior vena cava (IVC) patency. Although stent placement is a standard and frequently performed treatment, very few IVC stent-related complications, such as stent fractures, have been reported. Here we present a case series and a comprehensive review of IVC stent fractures in patients with BCS. The most common characteristic of IVC stent fractures is a protrusion of the proximal segment of the IVC stent into the right atrium and its systolic and diastolic movements along with heart rhythms. Accurate stent deployment, large-diameter balloon dilation, patient breath-holding training, preferential selection of a triple stent, and the use of an internal jugular vein approach to stent deployment may ensure precise stent localization and avoid postoperative complications.

To find out the association between categorical variables, Chi-square test was used. p-value of

Aim. To summarize and broaden the idea about mechanisms of acute coronary insufficiency development and pathophysiological features of myocardial reperfusion injury. Today, in the event of acute coronary syndrome, according to the latest recommendations for myocardial revascularization, percutaneous coronary intervention should be performed to determine the anatomy of coronary artery lesions and further percutaneous therapy. But in some patients, after blood flow restoration, reperfusion injury occurs, which is primarily related to the duration of ischemia, infarct size, and the myocardial resistance to ischemia. Treatment of myocardial infarction, like any treatment method, has evolved. In the 60s of the previous century, it included morphine, oxygen, warfarin and bed rest for 4–6 weeks. Then, during the 70s, it consisted of morphine, oxygen, lidocaine, warfarin, bed rest for 2–3 weeks and possibly coronary angiography for the further bypass surgery. The late 1970s saw the rapid progress in thrombolysis, first intravenous and then intracoronary. And starting in the early 1980s, since G. Hartzler performed the first balloon angioplasty for acute coronary artery occlusion, the stage of mechanical myocardial reperfusion has come. At the same time, knowledge about the pathophysiology of acute coronary ischemia was deepened. The World Health Organization developed ECG criteria for acute myocardial infarction using population-based studies in the 1950s–1970s, and additional four normative European regulations since then were issued defining concepts, key points of diagnosis and possible complications of myocardial infarction. Conclusions. The development of myocardial ischemic-reperfusion injury is a staged process that has a complex pathogenesis, its own clinical manifestations, and an association with more negative long-term outcomes of myocardial infarction treatment. Its main components are myocardial swelling involving cardiomyocytes, endotheliocytes, and the interstitial space; downregulation of cytoskeleton and disruption of sarcolemma integrity; increased vascular wall permeability; spasm of arterioles; intravascular accumulation of platelets and leukocytes, and the resultant the most severe form of myocardial damage is intramyocardial hemorrhage. Clinically, this is manifested by the no-reflow phenomenon following percutaneous coronary intervention.

Abstract Objective Esophageal cancer is a common malignancy globally. Most patients in sub-Saharan Africa present at advanced stage not amenable to curative therapy. Stenting provides palliation for these patients. In Uganda, many endoscopy units can perform diagnostic endoscopy but only a handful routinely perform endoscopic interventions like stenting. We describe esophageal cancer patients who underwent esophageal stenting intending to highlight its importance in a resource-limited setting. Endoscopy reports were reviewed for patients who underwent evaluation for esophageal cancer at Lubaga Hospital from December 2014 to March 2022. Results 315 records of patients with esophageal cancer were reviewed. Male to female ratio was 2:1. 188(60%) patients were 60 years and above. 268 (85%) esophageal lesions were described as fungating, friable or polypoid. 249 (79%) tumors were in mid or distal esophagus. 66% esophageal lesions caused severe luminal obstruction not traversable by the scope. 164 (52%) patients did not opt for stenting due to personal and other reasons. Stenting wasn’t successful in 7 out of the 148 patients who underwent either primary or tandem stenting. Despite 207 (66%) of patients with advanced esophageal cancer presenting with endoscopically non-traversable tumors, endoscopic stenting was still possible with a technical success rate of 95.3%.

The antithrombotic therapy is an important part of medical treatment in percutaneous coronary interventions (PCI). The so called dual antiplatelet therapy (DAPT), usually including acetyl salicylic acid (aspirin) plus platelet P2Y12 receptor inhibitors is an important part of that therapy. The careful balance between the protective effect regarding thrombotic/ischemic events and the risk of bleeding is an important task of the attending physician. Apart of the standard dosing regiments, in some of the cases a judgment regarding shortened or prolonged DAPT, as its de-escalation is mandatory. To present the causes and the way of application of that individualized approach in patients with PCI is the aim of this review.

Transcatheter closure of patent ductus arteriosus (PDA) is now the standard of care with some exceptions. Best treatment for peripheral pulmonary artery (PA) stenosis in small children is still debatable. Surgical augmentation, balloon dilatation, and stenting are the available options with each having its own risks and limitations. Here, we are reporting complete transcatheter management of three cases of congenital rubella syndrome who had PDA and left branch PA stenosis by device closure and stent placement, with successful outcome in two cases and complication, leading to surgery in one. We also share our understanding of case selection for a better outcome.

Abstract Background and Aims Endovascular therapy (EVT) is recommended in femoropopliteal (FP) lesions shorter than 25 cm by current guidelines; however, diffuse FP lesions remains challenging for EVT. The aim of this study was to investigate the efficacy of EVT with the latest devices for FP lesions longer than 25 cm. Methods This retrospective multicenter registry analyzed patients presented peripheral artery disease (PAD) having FP lesions longer than 25 cm who underwent EVT using the latest devices between 2017 and 2021. The primary outcome was restenosis 1 year after EVT. Results The present study enrolled a total of 504 PAD patients with 614 lesions undergoing EVT for diffuse FP lesions. The Kaplan–Meier analysis showed that the rates of freedom from restenosis and clinically‐driven target lesion revascularization were 79.3% and 82.4% 1 year after EVT, respectively. The multivariate Cox proportional hazards regression analysis showed that clinical features associated independently with restenosis risk were cilostazol use (adjusted hazard ratio, 0.49 [0.32–0.74]; p = 0.001), reference vessel diameter (RVD) (0.72 [0.58–0.89] per 1‐mm increase; p = 0.002), and P3 segment involvement (2.08 [1.33–3.26]; p = 0.001). The Kaplan–Meier analysis was conducted to compare the primary patency between cases with and without a small RVD, P3 involvement, and/or lack of cilostazol; any risk factors were related to a worse primary patency rate, compared with cases without risk factors. Conclusion In the current EVT era, the primary patency at 1 year was acceptable at 79.3% in patients with FP lesions longer than 25 cm. A small vessel and P3 segment involvement might be associated with a poor 1‐year patency rate after EVT, whereas cilostazol administration might contribute to reducing restenosis.

Turner syndrome (TS) is the most common chromosomal abnormality affecting females and cardiac abnormalities have been described in up to 50% of patients. Although coarctation represents one of the most frequent cardiac malformation, treatment options in these patients represent an area of debate, due to associated aortopathy and risk for aortic dissection. In addition to the contradictory data found in the literature, regarding the safety profile and utility of stenting of coarctation of the aorta in TS patients, we present the case of a patient of pediatric age, who successfully underwent the procedure, being free from periprocedural and short-term complications. Beside the presentation itself, we aimed to review and summarize the data available in the literature regarding this topic. As a conclusion, we emphasise the role of minimally invasive interventional therapy and wish to underline the need of further, larger scale studies and guidelines in this patient group. Given the related aortopathy, all preventive measures should be undertaken to avoid aortic dissection during stent implantation in this vulnerable population. Although the evolution of our patient was favorable, data found in the literature is somewhat contradictory and a close follow-up is indicated to help evaluate the risk of long-term complications.

Modified Blalock‒Taussig shunt is a commonly performed palliative cardiac surgery. Complications like early or late occlusion have been reported in approximately 10% of patients. Thrombosis, stenosis, or kinking are possible mechanisms that lead to shunt obstruction which may be life-threatening and need urgent intervention in form of medical, surgical, or interventional catheterization. Traditionally, these patients are managed in the operating room with shunt revision but with advancing techniques, percutaneous interventions are being increasingly deployed to salvage these patients effectively. We describe our experience of two cases of blocked modified Blalock‒Taussig shunt, which was successfully managed by stenting the shunt.

Stenosis of the iliac veins is common in patients with chronic venous insufficiency. The article describes the methods for the diagnosis and treatment of iliac vein stenosis. The causes of iliac vein stenosis include extravasal compression or the consequences of ileofemoral thrombosis. Stenosis of the iliac veins exists in 1/4 of the entire adult population, but clinical manifestations do not occur in all patients. Stenosis of the iliac veins should be considered in case of an unknown edema, more often in the left lower extremity, since venous duplex ultrasound of lower extremities is not sensitive and specific enough when examining the veins above the inguinal ligament. The most accurate diagnostic method is intravascular ultrasound (IVUS) but the appeared computed tomography angiography (CTA) and magnetic resonance angiography (MRA) with high-quality images have become a good replacement for IVUS. The main method of treatment of iliac vein stenosis, besides stenting, isindispensable drug therapy consisting of antithrombotic and phlebotonic drugs.

Internal stenting of the upper urinary tract is a widespread urological surgery. Its frequency in modern practice is high and continues to grow due to the widespread use of endourological, percutaneous, and laparoscopic interventions. The presence of a stent in the patient's body often leads to a decrease in the quality of life due to the occurrence of stent-dependent symptoms, which often requires urgent hospitalization. According to various data, they are registered in at least 80% of patients. The most common stent-dependent symptoms are frequent and / or painful urination, urge to mix (up to imperative), nocturia, pain in the lumbar region, macrohematuria. According to existing data, a fair share of responsibility for the development of these symptoms lies with the distal (vesicular) curl of the internal stent, especially if the technology of its installation is not followed or the length of the drainage is incorrectly selected. The review describes methods for correct installation of internal ureteral stents by transurethral retrograde, antegrade, and laparoscopic approaches, as well as a method for installing and removing mono-pigtail drains. The internal drainage procedure is standard, so the focus is on the nuances and details of this widespread manipulation. The given cohort of patients and the range of surgical interventions indicate a significant experience of the authors in this issue. All illustrations are author's own and taken from the daily workflow. It should be noted that the modern understanding of the process and technological equipment ensure correct stenting when performing any interventions with any access. An adequate choice of installation method and correct positioning of the stent, knowledge of simple details and "secrets" allow not only to restore urodynamics, but also to effectively prevent the development of stent-dependent symptoms, thereby preserving patients quality of life.

The occurrence of tracheal fistulas of ischemic genesis combined with the failure of esophagogastroanastomosis and the communication between them is a rare and formidable complication after esophagectomy with mediastinal lymphadenectomy due to its anatomical position and extensiveness. However, it is insufficiently documented in the literature, both in terms of treatment and in terms of its causes. This observation aims to demonstrate the rare cause of this complication and the atypical successful treatment. In this case, a patient with squamous cell carcinoma G2 of the middle third of the esophagus and TNM stage cT3NxM0. On the McKeown thoracoscopic-laparotomy esophagectomy intraoperatively a short arterial vessel with a diameter of about 3 mm, which passed through the paracancerous infiltration and supplied blood to the esophagus and trachea revealed. The vessel was not isolated from the infiltrate, but was clipped and crossed between the aorta and infiltrate to maintain surgery ablastic. On the 7th day after the operation the insolvency of esophagogastroanastomosis, the fistula of the trachea with mediastinum and the communication between the leak of esophagogastroanastomosis and the fistula of the trachea were diagnosed. We consider this combination as a special case of esophagogastroanastomosis fistula, complicated by the communication between the right pleural cavity and pneumothorax. According to our experience, partial leak of esophagogastroanastomosis successfully heals by secondary tension within 10–15 days against the background of cervicotomic wound drainage and feeding through a nasointestinal tube. In this case there was a leak of saliva in the mediastinum and its penetration into the lumen of the trachea and the right pleural cavity. Surgical diversion of the fistula and stenting of the trachea were considered, but not applied, as the fistula in our opinion was controlled, but the aggressive content of the gastric conduit prevented healing. The patient was on assisted lung ventilation with minimal pressure support and inflow increased oxygen fractio. For this reason, we considered the best stenting of the esophagogastroanastomosis leak area to be covered with a stent in order to stop the aggressive content of the gastric stem from entering the fistula, which led to the successful treatment of the developed severe complication. It should be noted that this method of treatment may be ineffective in patients who need pressure support during ventilation.

Vascular endoscopic imaging is known for a long time but has never made its way into clinical routine. Reasons for that are the complexity, lack of low-cost portable systems, and the lack of suitable endoscopes providing high image quality with small dimensions. In addition, an interruption of the blood flow caused by the device and the opacity of blood are difficult to manage. In the past we have already developed ideas to overcome these difficulties and now we present a feasibility test of a thin diameter ureteroscope for observation of vascular procedures. The imaging system was tested in a phantom where side branches were explored, a stent was placed and a simulated aneurysm coiled.

Introduction: The treatment of complex arterial lesions with long occlusions and involvement of the bifurcation of the tibial arteries remains a technical challenge in the endovascular area that often culminates in the choice of a conventional surgical alternative. Given the similarities in arterial caliber and necessary material, the adaptation of techniques used in lesions of bifurcations in the coronary circulation to the infrapopliteal territory has allowed a change in the treatment paradigm. Material and methods: This article presents a clinical case of a patient with complex peripheral arterial disease treated with the double kissing (DK) crush technique. Clinical case: 74-year-old male patient, hypertensive, and smoker, previously submitted to endovascular exclusion of infra-renal abdominal aortic aneurysm and bilateral saphenectomy, diagnosed with chronic limb-threatening ischemia of the left limb – Rutherford 4. AngioCT revealed a long (30 cm) femoropopliteal occlusion with rehabilitation at the level of the tibioperoneal trunk (TPT). Despite the extent and location of the lesion, the patient's surgical history, the absence of a great saphenous vein, and multiple previous femoral surgical approaches led the patient to be initially proposed for endovascular treatment using the DK crush technique. The lesion was recanalized through percutaneous access of the ipsilateral superficial femoral artery, and a guidewire was placed in the peroneal and posterior tibial arteries. The TPT bifurcation was predilated in kissing (1st kissing balloon), and a balloon-expandable stent (Xience Sierra® 3×18mm) was placed in the posterior tibialis (PT). Subsequently, a second balloon-expandable stent (Xience Sierra® 3.5×18mm) was placed in the peroneal artery with the consequent crush of the proximal portion of the 1st stent. The PT guidewire was removed and reintroduced through the stent mesh, and then the second kissing balloon of the bifurcation was performed, with an excellent angiographic result. Finally, femoropopliteal angioplasty was performed with placement of self-expanding stents (Zilver PTX®) in increasing degrees. The patient had no complaints and maintained patency of the entire arterial axis at nine months of follow-up, namely the peroneal and PT arteries, evident on the control ultrasound. Conclusion: In the case presented here, the adaptation of the DK crush technique to the tibial-peroneal territory allowed the effective revascularization of a complex arterial lesion, with good results in the medium term.

Introduction : May Thurner Syndrome (MTS) is a clinical condition as a result of an anatomical compression of the left common iliac vein by the fifth lumbar vertebra posteriorly, and by the right common iliac artery anteriorly associated with symptomatology. Affirming the diagnosis can be difficult and intravascular ultrasonography (IVUS) can help in the definitive decision. Clinical Case: A 43 years old man with a past history of a deep venous thrombosis of the left lower limb presented at our clinical appointment with a 5 months history of left limb edema and inability to stand up for long periods of time, disabling him from working. A venous-CT scan was obtained to diagnose the condition but was inconclusive. It was proposed to the patient to carry out a phlebography and an IVUS to eliminate the doubt and increase the diagnosis acuity, which was accepted. A phlebography and IVUS confirmed a significant compression of the left common iliac vein (image 1). The patient was treated by endovenous placement of an Abre 16/80 medtronic stent followed by dilatation with a 16/40 balloon Boston scientific. The phlebography and IVUS control showed complete resolution of the compression. (Image 2) Discussion/Conclusion: The diagnosis of MTS can be difficult and implies a high degree of clinical suspicion. The TC scan alone may not be diagnostic. The phlebography, and especially the more recent IVUS technology increases the accuracy of the diagnosis. Emergence of endovascular surgery revolutionized the treatment of obstructive venous disease, and became the gold standard of treatment. However, the implantation of stents in a young population implies additional cautions due to the lack of knowledge about their behavior over the long term. In this clinical case, the IVUS allowed us to reach the diagnosis and to increase the therapeutic accuracy of the ilio- cava stenting. We recommend the routine use of IVUS in the management of MTS.

The review describes morbidity, mortality and possible complication rates for diabetic patients with peripheral arteries disease. The article demonstrates the modern tendency in the surgical treatment of peripheral arteries atherosclerosis, shows and compares worldwide results of endovascular and open revascularization. The authors have assessed the risk of amputation for patients with diffuse peripheral arteries disease and described basic treatment principals for better chronic ischemic ulcer healing.

Introduction: Internal carotid artery (ICA) stenosis in a majority is caused by atherosclerotic plaque. Symptoms of ICA stenosis manifest most likely a transient ischemic attack (TIA). The dynamics of ICA stenosis progression is unpredictable, the disease may progress quickly or slowly or remain stable for many years. The method of treatment implemented also depends on it. The task of pharmacological treatment is to reduce the progression of the disease and protect against the onset of stroke. Among the invasive methods of treating ICA stenosis, the standard procedure is endarterectomy of a carotid artery (CEA), i.e. surgical removal of atherosclerotic plaque. Another method of treatment is endovascular carotid artery stenting (CAS). CAS should be considered especially in the case of re-operated patients, also after radiotherapy and tracheostomy. CAS is a less invasive procedure, it avoids complications typical for CEA such as cranial nerve palsy or complications at the site of the wound. On the other hand, the risk of postoperative ischemic stroke is greater in the case of CAS. In recent years, the improved CAS method seems to be the implantation of dual-layered mesh-covered carotid stent systems (DLS). Case report: We present the case of a 69 old man, long-term smoker, with hypertension and coronary heart disease. In 2001 diagnosed with larynx cancer and underwent surgical laryngectomy and radiotherapy. He was admitted in scheduled mode due to symptomatic carotid artery stenosis. In USG examination there was visible stenosis of the right internal carotid artery (80%) caused by an unstable atherosclerotic plaque with irregular structure and thrombotic clots. Due to the obvious difficulties of performing endarterectomy following radiotherapy in the neck area and laryngectomy, the endovascular method has been considered. In spite of the unstable plaque, which is a contraindication to perform the endovascular procedures CAS has been decided to perform. The patient underwent implantation of a dual-layered carotid stent in the combination with proximal balloon occlusion protection with a MoMa device. After procedure arteriography confirmed the optimization of the carotid artery flow and the correct position of the stent. The treatment was carried out without complications. After a few days of hospitalization, the patient was discharged home. Discussion: The method of treatment of internal carotid artery stenosis is selected taking into consideration morphology and localization of atherosclerotic plaque, anatomical conditions and the local condition of the surgical area as well as the general condition of the patient and coexisting diseases. On the one hand, the patient underwent cervical radiotherapy and laryngectomy which are contraindications for CEA. On the other hand, an atherosclerotic plaque was unstable with the features of stratification which is a contraindication to the performance of CAS. In the described case it was decided to make implantation of dual-layered carotid stent system (DLS) connected with proximal balloon occlusion protection with a MoMa device allowed to reduce the risk of embolization.

Background Despite aggressive medical therapy, the risk of recurrent stroke in patients with symptomatic intracranial arterial (ICA) disease is as high as 15% per year. In patients with severe stenosis (>70%) and in certain high-risk groups, the risk of recurrent stroke has been reported to be as high as 25% per year. Objective Our study aimed to follow-up the patients after ICA stenting by using transcranial duplex (TCD). Patients and methods This is a retrospective single-center study carried out on data of patients recruited to Neurovascular Unit of El Mataria Teaching Hospital during the period from June 2015 to June 2016. A total of 25 patients were enrolled. TCD before and after stenting data were collected from the patients' files. Results Our study showed significant decreased in mean flow velocity and percent of stenosis after intracranial stenting. Conclusion Our study concluded that TCD is a good method for follow-up of patients after ICA stenting.

Introduction: Obstruction to hepatic venous outflow is a rare disease with a potentially fatal outcome, if not recognised and managed promptly. The level of obstruction can vary, anywhere from the small hepatic venules to the entry point of the Inferior Vena Cava (IVC) into the right atrium. The original patients that Budd-Chiari described had acute hepatic vein thrombosis but this syndrome now encompasses various hepatic venous outflow blocks, of which a membrane in the IVC is the most common anatomical form of obstruction. Pure IVC obstruction is commonly seen among Asians. Aim: To study the clinical and diagnostic profile of patients presenting with IVC obstruction and to evaluate the treatment efficacy and safety of percutaneous transluminal angioplasty. Materials and Methods: For this prospective, descriptive study, from November 2015 to August 2019, a total of 21 patients were admitted with obstruction of hepatic venous flow. Most of the patients were young adults. Clinical features, aetiologies and coagulation profiles were studied. Ascites, pain abdomen and pedal oedema were common presentations. Diagnosis was established by clinical examination and was confirmed by ultrasound-doppler study, computed tomography and conventional angiography. Statistical analysis was done by using statistical package for social sciences IBM SPSS statistics for Windows, version 20.0. The data were expressed as percentages of study population while, continuous data were expressed as mean±standard deviation. Results: The mean age of the population was 24.7±2.9 years, with a female preponderance. (male: female=1:2). IVC angiography was done in 15 patients. Seven of the 15 patients had diffuse narrowing of IVC. Eight patients had focal or segmental narrowing of IVC, among them seven patients underwent Percutaneous Transluminal Angioplasty (PTA) with stenting. The venous access was obtained from femoral vein. The stenoses were crossed with either guide wire or Brocken brough needle with Mullins sheath. Three patients did not need predilatation. In four patients, obstructed IVC was dilated with Inoue balloon and then self-expanding stents were placed. Success was achieved in all cases, with significant drop in the pressure gradients from 20±5 mmHg before procedure to 3±2 mmHg immediately after the procedure. After PTA, all seven patients had either total relief or decrease of symptoms and clinical signs of hepatic venous obstruction. No major complications were observed and no repeat interventions were required. The mean postprocedural follow-up was six months that showed good outcomes with good stent patency. Conclusion: Chronic obstruction of IVC presents with abdominal pain, progressive ascites and portal hypertension in young adults, with mild abnormality of liver function tests. The IVC obstruction can be due to an obstructive membrane or segmental stenosis or diffuse narrowing of IVC. PTA with stenting can be done safely and it effectively relieves the symptoms and venous congestion and can be considered as the first decompressive procedure in patients with IVC stenosis.

Stenting has become one of the primary procedure to treat vertebral artery ostium stenosis patients. Postoperative instent restenosis (ISR) of the stenting is still one of the unsolved issues and requires systematic and further investigation. Through imaging assessments, ISR could be identified and evaluated in clinical practice and researches.

Objectives: The aim of this study was to evaluate intraocular pressure (IOP) and retinal nerve fiber layer (RNFL) changes in patients with carotid artery stenosis (CAS) after carotid artery stenting. Materials and Methods: This study was conducted as a cross-sectional, non-randomised clinical case series. Fifteen male patients (mean age: 63.6±9.1) with CAS and more than 70% carotid artery narrowing were included. All of the patients were followed in the department of neurology and were operated in the interventional radiology division. Eighteen healthy male subjects (mean age: 63.7±5.3) were included in the control group. All of the healthy subjects had a detailed ophthalmological examination and subjects with any chronic eye disease were excluded from the study. All of the participants had a detailed ophthalmological examination including tonometry using Goldmann applanation tonometry and RNFL analysis using optical coherence tomography (RTVue-100 5.1). Results: There were no ocular ischemic symptoms in any of the participants. The mean IOP value was 15.1±2.1 mmHg in the control group and 16.6±2.4 mmHg before stent implantation, 16.4±2.2 mmHg at 1 week after implantation, 16.6±2.5 mmHg at 1 month after implantation, and 16.7±2.9 mmHg at 3 months after implantation in the CAS group. Mean RNFL thickness was 105±6 µm in the control group; in the CAS group, mean RNFL thickness values were 98±27 µm before stent implantation and 103±11 µm, 101±10 µm, and 101±11 µm at 1 week, 1 month, and 3 months after stenting. There were no significant differences between the CAS group and control group regarding IOP and RNFL thickness values (p>0.05). IOP and RNFL thickness also did not show any statistically significant changes from preoperative measurements in 3 months postoperative follow-up in the CAS group (p>0.05). Conclusion: IOP and RNFL thickness remained unchanged after carotid stent implantation in carotid artery stenosis patients with no signs of ocular ischemic syndrome.

To date, cardiovascular diseases occupy the first place in the structure of total morbidity and mortality in many countries. In 2013 in the Russian Federation from cardiovascular disease died 1 million 799 thousand people, from the bottom 529.8 thousand from coronary heart disease, the primary role belongs to myocardial infarction and its complications. Currently, the "gold standard" for the diagnosis of coronary heart disease, including myocardial infarction, remains coronary angiography; the main objectives of coronary angiography are to assess the features of the coronary anatomy, determination of the possibility of endovascular treatment of myocardial infarction and revascularization by stent implantation. Despite the constant improvement of technology and the progress made in relation to pharmacological support, percutaneous coronary intervention (PCI) is an invasive manipulation, which is associated with a certain risk. Diagnostic criteria for myocardial infarction 4a type include increasing the level of troponin above 5 rules of 99th the upper threshold reference values within 48 hours after the PCI procedure, in patients with normal troponin increased (≤ 99th the upper threshold reference values), or a level of troponin 20 % or more in patients with initial high level troponin combined with evidence of prolonged myocardial ischemia. Stent when performing percutaneous coronary interventions, accompanied by the activation of thrombogenic reactions, can lead to thrombosis and development 4b type. To the diagnostic signs of the myocardial infarction 4b type are the stent thrombosis, angiographic proven and/or at autopsy, in combination with increased troponin level at least one greater than the 99th the upper threshold reference values. Stent when performing PCI, accompanied by the activation of thrombogenic reactions, can lead to thrombosis and development myocardial infarction 4b type. The diagnostic signs myocardial infarction 4b type are the stent thrombosis, angiographic proven and/or at autopsy, in combination with increased troponin level at least one greater than the 99th the upper threshold reference values. You should consider the fact that the setting of drug-eluting stents increases the period of their endothelization after implantation, which in turn increases the likelihood of late thrombosis and is an indication for long-term dual antiplatelet therapy. The article describes the varieties of myocardial infarction associated with PCI, an algorithm for the diagnosis and management of patients in accordance with current clinical recommendations.

Aim. To estimate whether optimal antiplatelet therapy can be selected in terms of CYP2C19 polymorphism. Subjects and methods. The prospective randomized trial included 124 patients (93 men and 31 women) who were to undergo percutaneous coronary intervention. They initially received dual antiplatelet therapy: clopidogrel 75 mg + acetylsalicylic acid (ASA) 300 mg. Genetic testing was performed in all the patients to reveal the carriage of allelic variants of the genes of cytochrome P-450 isoenzymes and the efficiency of antiplatelet therapy was evaluated. The carriers of one allele (CYP2C19*2/*1) were randomized into 3 subgroups according to further antiplatelet therapy. The therapy was not changed in Subgroup 1. The dose of clopidogrel was increased up to 150 mg/day and that of ASA remained unchanged in Subgroup 2. In Subgroup 3, the therapy was completely changed to the regimen: ASA 300 mg + ticagrelor 90 mg twice daily. Three days later, platelet aggregation was reinvestigated in all the three subgroups. Results. In our investigation, the prevalence of carriage of at least one of the CYP2C19*2 alleles was about 35%. Comparison of the baseline platelet aggregation levels during the same platelet therapy showed statistically significant differences between the carriers and non-carriers: 32.7±11.6 and 44.8±12.9 (p=0.0024). Compared with the baseline values, there was a drug therapy switching-induced reduction in platelet aggregation in Subgroups 2 and 3 (p=0.0001 and p=0.0056, respectively). No statistically significant differences were found in Subgroup 1. Conclusion. The determination of CYP2C19 gene polymorphism allows a personalized approach to be applied in antiplatelet therapy for all patients with coronary artery disease.

Advanced squamous cell carcinoma of the oesophagus and gastroesophageal junction usually requires palliative treatment, and the method of choice is stenting. There are several types of stents currently available, including: self-expandable metallic stents (fully or partially covered); self-expandable plastic stents; biodegradable stents. Each of the mentioned stents has its advantages and limitations, and requires a proper, patient-tailored selection. Due to the close anatomical relationship between the oesophagus and bronchial tree, some patients may require bilateral stenting. Oesophageal stenting may not only be considered as a palliative procedure, but can also be implemented to alleviate dysphagia during preoperative chemotherapy and/or radiotherapy.

We report our experience with a stent migration after right ventricle outflow tract stenting and converted to patent ductus arteriosus stenting in Tetralogy of Fallot (TOF) with severe infundibular stenosis. Finally, the patient achieved to TOF repair, and the migrated stent was removed without any complication.

Purpose: Previous studies comparing percutaneous coronary intervention (PCI) with coronary artery bypass graft surgery (CABG) in patients with unprotected left main or three-vessel coronary artery disease (LM-3VD) have excluded patients at high surgical risk. We compared clinical outcomes after PCI with drug-eluting stents to CABG in high surgical risk patients with LM-3VD. Methods: Patients with symptomatic LM-3VD who had Society of Thoracic Surgeons (STS)-predicted operative mortality > 5% and were undergoing either PCI with drug-eluting stents or CABG at a tertiary care center from January 2009 to December 2010 were enrolled in this nonrandomized prospective study. Results: Mean STS score was 14.5 ± 5.8% for PCI (n=83) vs. 13.6 ± 7.1% for CABG (n=187) (P=0.31). After mean follow-up of 37 months, incidence of the composite primary endpoint (death, myocardial infarction or stroke) was 42.2% for PCI and 39.6% for CABG (P=0.69, hazard ratio 1.3, 95% confidence interval 0.5-2.8). There were no differences in the individual components of the primary endpoint between PCI and CABG. Repeat revascularization was 30.1% for PCI vs. 9.6% for CABG (P=0.001). Major adverse cardiac and cerebrovascular event rates were similar between PCI and CABG, 50.6% vs. 42.2%, respectively (P=0.23). Patients in the PCI group were less likely than those in the CABG group to be discharged to a nursing home (12.1% vs. 47.1%, P 5%.

A 1.7 kg infant with obstructed supracardiac total anomalous pulmonary venous drainage (TAPVD) presented with severe pulmonary hypertension secondary to vertical vein obstruction. The child, in addition, had a large omphalocele that was being managed conservatively. The combination of low weight, unoperated omphalocele, and severe pulmonary hypertension made corrective cardiac surgery very high-risk. Therefore, transcatheter stenting of the stenotic vertical vein, as a bridge to corrective surgery was carried out. The procedure was carried out through the right internal jugular vein (RIJ). The stenotic segment of the vertical vein was stented using a coronary stent. After procedure, the child was discharged well to the referred hospital for weight gain and spontaneous epithelialization of the omphalocele. Stenting of the vertical vein through the internal jugular vein can be considered in very small neonates as a bridge to repair obstructed supracardiac total anomalous venous drainage.

Purpose: Coronary artery bypass graft is the standard treatment for unprotected left main disease; however, some patients are poor surgical candidates due to comorbidities. We assessed the safety and clinical outcome of elective, unprotected left main coronary artery stenting in nonsurgical patients. Methods: Between October 2004 and June 2006, 50 consecutive patients underwent elective, unprotected left main coronary artery stenting at our institution. Patients were followed for a median of 16 and 96 months and clinical outcomes monitored. Results: Median logistic euroSCORE was 28.6 (interquartile range: 14.6-43.4). Median baseline left ventricular ejection fraction (LVEF) was 50%. Procedural success rate was 100%. The rates of cerebrovascular accident, myocardial infarction, target vessel revascularization and cardiovascular death were 2%, 4%, 4% and 2%, respectively, at 30 days, 2%, 6%, 6% and 2% at 16 months, and 2%, 6%, 12% and 4% at 96 months. Major adverse cardiac and cerebrovascular event rate was 12% at 30 days, 16% at 16 months and 24% at 96 months. Median LVEF at 16 months was 55%, significantly improved from baseline (P
