REVIEW
Resmi Ann Charalel, Suresh Vedantham
The presence of cancer increases the risk of deep vein thrombosis (DVT), DVT recurrence, and treatment-related bleeding, and therefore offers distinctive clinical considerations when planning treatment. Anticoagulation with a low-molecular-weight heparin is the preferred initial and long-term therapy in cancer patients. Inferior vena cava filters may be used judiciously for patients with cancer-related DVT who have contraindications to anticoagulation or who exhibit breakthrough pulmonary embolism (PE) despite anticoagulation, but should be removed when the PE risk is felt to subside...

OBJECTIVE: Carotid endarterectomy (CEA) reduces stroke risk in selected patients. However, CEA risk profile may be different in older patients. We compared characteristics and outcomes of octogenarians and nonagenarians with those of younger patients. METHODS: Deidentified data from CEA patients were obtained from the Society for Vascular Surgery Vascular Quality Initiative (VQI) database. Prior CEA, carotid artery stent, or combined CEA and coronary artery bypass were excluded, yielding 7390 CEAs in octogenarians and nonagenarians (≥80 years of age) and 35,303 CEAs in younger patients (<80 years of age)...

OBJECTIVE: Central vein occlusion is a common complication related to central vein catheter insertion for haemodialysis which can be unmasked by an ipsilateral fistula creation, leading to a dysfunctional arteriovenous fistula (AVF). We describe an extra-anatomical venous bypass surgical procedure performed to maintain vascular access and reduce the symptoms of swelling of the ipsilateral upper limb, neck and face. MATERIALS AND METHODS: We report 20 consecutive patients with end-stage renal failure (ESRF) who had central vein occlusion and were not amenable to endovascular intervention...

Importance: Ischemic postconditioning of the heart during primary percutaneous coronary intervention (PCI) induced by repetitive interruptions of blood flow to the ischemic myocardial region immediately after reopening of the infarct-related artery may limit myocardial damage. Objective: To determine whether ischemic postconditioning can improve the clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Design, Setting, And Participants: In this multicenter, randomized clinical trial, patients with onset of symptoms within 12 hours, STEMI, and thrombolysis in myocardial infarction (TIMI) grade 0-1 flow in the infarct-related artery at arrival were randomized to conventional PCI or postconditioning...

Importance: Bivalirudin has been associated with reduced bleeding and mortality during primary percutaneous coronary intervention for ST-segment elevation myocardial infarction (STEMI). However, increased rates of acute stent thrombosis (AST) have been noted when bivalirudin is discontinued at the end of the procedure, which is perhaps related to this medication's short half-life. Objectives: To evaluate the clinical effect of procedure duration on AST when either bivalirudin or heparin plus glycoprotein IIb/IIIa receptor inhibitor (GPI) is used...

INTRODUCTION: The so-called stent-related symptoms caused mainly by detrusor overactivity due to distal ("cystic") curl of the internal stent are common among patients with this type of drainage. The need for long-term stenting makes the quality of life of cancer patients one of the challenging problems of modern urology. The aim of this study was to optimize treatment of stent-related symptoms in cancer patients with internal long-term stents by complementing the treatment regimen with m-anticholinergic solifenacin...

BACKGROUND: The efficacy for the treatment of large carotid cavernous aneurysms (CCAs) was compared between conventional endovascular treatments, stent-assisted coiling (SAC), parent artery occlusion (PAO), and the flow diverter (FD). METHODS: Between January 2001 and December 2015, 49 patients with large, broad-necked, unruptured CCA underwent endovascular treatment at our institution. We performed PAO in 22 patients, SAC in 18 patients, and FD in 9 patients. Safety and efficacy were assessed in all patients by periodic clinical and radiological examinations during a 6-month follow-up...

REVIEW
L Derex, T-H Cho
Recent randomized trials have demonstrated the efficacy of stent retriever thrombectomy, in association with intravenous thrombolysis, in acute ischemic stroke related to the occlusion of the distal internal carotid artery or the proximal middle cerebral artery within six hours of symptom onset. Mechanical thrombectomy should be performed as soon as possible after symptom onset. High age alone should not be considered as a contraindication for mechanical thrombectomy. Mechanical thrombectomy is recommended in acute ischemic stroke patients with large vessel occlusions and salvageable brain tissue if intravenous thrombolysis is contraindicated...

Temporary drainage of the upper urinary tract by internal ureteral stents is a routine procedure in endourology. However, it is associated with a clear side-effect profile. Our aim was to evaluate prevention and treatment options of stent-related symptoms. We carried out a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using MEDLINE and SCOPUS, and identified 107 appropriate records. A high number of these studies showed clear methodological limitations...

INTRODUCTION: Cancer of the esophagus is among the leading cause of cancer deaths in Punjab, India. Patients generally present with dysphagia as their first symptom and more often they have advanced disease at the time of presentation to a tertiary care centre. Palliative procedures have important roles in this setting. Stenting is the best option to palliate the symptoms of dysphagia, from which patient is suffering the most. AIM: To know the success rate, early and long term complications and mortality in esophageal stenting, when it was done in malignant esophageal stricture patients...

There is increasing recognition of tracheobronchomalacia (TBM) in patients with respiratory complaints, though its true incidence in the adult population remains unknown. Most of these patients have an acquired form of severe diffuse TBM of unclear etiology. The mainstays of diagnosis are dynamic (inspiratory and expiratory) airway computed tomography (CT) scan and dynamic flexible bronchoscopy with forced expiratory maneuvers. While the prevailing definition of TBM is 50% reduction in cross-sectional area, a high proportion of healthy volunteers meet this threshold, thus this threshold fails to identify patients that might benefit from intervention...

Mediastinitis is a rare complication of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Recent reports of infectious complications following EBUS-TBNA involved oropharyngeal bacteria. Here, we report 2 unusual cases of post-EBUS-TBNA mediastinitis involving Streptococcus pneumoniae and Pseudomonas aeruginosa, which were likely the result of direct inoculation of the organisms at the time of transbronchial needle aspiration. The first case was successfully treated with computed tomography-guided drainage and antibiotics, whereas the second case had >50% distal tracheal obstruction and near total occlusion of the left main stem bronchus, requiring rigid bronchoscopy, stent placement, debulking, and antibiotics...

Local and systemic reactions to implanted metallic devices, particularly to those containing nickel, are well documented. Metal ions are released due to exposure of the metal to blood, proteins, other body fluids, and sheer mechanical stress. Metal ions then complex with native proteins and become antigens, which can elicit hypersensitivity reactions. Another case report depicts a specific allergic complication (early stent occlusion) related to metallic biliary stent implantation. We present a case of allergic symptoms, associated with eating, in a patient who developed nickel sensitivity after biliary metal stent placement confirmed by allergic skin testing to the same metallic biliary stent placed one year earlier...
