Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT)...

INTRODUCTION: Medical treatment, cerebrospinal fluid (CSF) shunting, and optic nerve sheath fenestration are standard treatments for increased intracranial pressure (ICP) in patients with idiopathic intracranial hypertension (IIH). Venous sinus stenting provides a novel alternative surgical treatment in cases of venous sinus stenosis with elevated ICP. METHODS: 12 consecutive subjects with papilledema, increased ICP, and radiological signs of dural sinus stenosis underwent cerebral venography and manometry...

Mesenteric vascular insufficiency is a serious medical condition that may lead to bowel infarction, morbidity, and mortality that may approach 50%. Recommended therapy for acute mesenteric ischemia includes aspiration embolectomy, transcatheter thrombolysis, and angioplasty with or without stenting for the treatment of underlying arterial stenosis. Nonocclusive mesenteric ischemia may respond to transarterial infusion of vasodilators such as nitroglycerin, papaverine, glucagon, and prostaglandin E1. Recommended therapy for chronic mesenteric ischemia includes angioplasty with or without stent placement and, if an endovascular approach is not possible, surgical bypass or endarterectomy...

A 38-year-old woman with a history of recurrent deep venous thromboses (DVTs) on chronic anticoagulation presented with acute left leg swelling. The patient was diagnosed with an acute left lower extremity (LLE) DVT in the setting of May-Thurner syndrome for which treatment with unfractionated heparin was started. Her hospital course was complicated by a new diagnosis of heparin-induced thrombocytopenia (HIT), with an incidental discovery of a large tricuspid valve mobile mass on a transthoracic echocardiogram (TTE)...

May-Thurner syndrome (MTS) also known as Cockett's syndrome is a rare condition responsible for 2%-3% of all cases of deep venous thrombosis (DVT). The thrombosis results from mechanical compression of the left common iliac vein against the body of the fifth lumbar vertebra by the right common iliac artery. Repetitive hyperplasia of the venous wall by compression results in spur formation that in turn causes venous flow obstruction and results in the DVT. Our case is a young female who had acute extensive proximal DVT due to MTS that was successfully managed using mechanical thrombectomy with a venous stent...

OBJECTIVE Neural interface technology may enable the development of novel therapies to treat neurological conditions, including motor prostheses for spinal cord injury. Intracranial neural interfaces currently require a craniotomy to achieve implantation and may result in chronic tissue inflammation. Novel approaches are required that achieve less invasive implantation methods while maintaining high spatial resolution. An endovascular stent electrode array avoids direct brain trauma and is able to record electrocorticography in local cortical tissue from within the venous vasculature...

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy...

BACKGROUND: In patients with acute ilio-femoral deep vein thrombosis (IFDVT), catheter-directed thrombolysis (CDT) aims to prevent the post-thrombotic syndrome (PTS). Adding intravascular high-frequency, low-power ultrasound energy to CDT does not seem to improve the immediate thrombolysis results but its impact on clinical outcomes at 12 months is not known. PATIENTS/METHODS: In this randomized-controlled trial, 48 patients (mean age 50±21 years, 52% women) with acute IFDVT were randomized to conventional CDT (n=24) or ultrasound-assisted CDT (USAT; n=24)...

BACKGROUND: Elevated body mass index (BMI) has been correlated with worse outcomes after treatment for idiopathic intracranial hypertension (IIH). Venous sinus stenting (VSS) has emerged as a safe and effective treatment for a subset of patients with IIH and evidence of venous sinus stenosis. However, the association between BMI and the efficacy of VSS remains poorly characterized. OBJECTIVE: To determine, in a retrospective cohort study, the effect of BMI on preoperative mean intracranial venous pressure (MVP) and post-VSS outcomes...

PURPOSE: To report patency rates for stent deployment for treatment of in-stent stenosis of the central veins of the chest in hemodialysis patients. MATERIALS AND METHODS: A retrospective analysis was performed on 29 patients who underwent 35 secondary percutaneous transluminal stent (PTS) deployments for in-stent stenosis within the central veins that were refractory to angioplasty and ipsilateral to a functioning hemodialysis access (in-stent PTS group). For comparison, patency data were acquired for 47 patients who underwent 78 successful percutaneous transluminal angioplasty (PTA) procedures for in-stent stenosis (in-stent PTA group) and 55 patients who underwent 55 stent deployments within native central vein stenosis refractory to angioplasty (native vein PTS group)...

Nutcracker syndrome is a clinical entity leading to renal venous hypertension due to extrinsic compression of the left renal vein by the superior mesenteric artery. Current surgical therapy involves placement of an oversized renal vein stent with partial protrusion into the inferior vena cava (IVC) to relieve stenosis and prevent stent migration. Here, we present a patient with intractable pain and hematuria secondary to nutcracker syndrome who underwent left renal vein stent placement and developed recurrent symptoms due to flow-limiting kinking at the left renal hilum, with partial obstruction of the IVC from pseudointimal hyperplasia...

Background The development and use of minimally invasive procedures provide improved options for the management of symptoms of chronic venous insufficiency. While many patients with iliac venous occlusive disease and superficial venous insufficiency improve with combined iliac venous stenting and correction of superficial venous reflux, some patients have symptoms which persist. The goal of this study was to identify clinical factors related to persistent symptoms in patients with leg swelling after treatment of both iliac vein stenting and thermal ablation...

We assessed contributions of thrombophilia to premature cardiovascular disease (CVD) events (≤ age 45) in 153 patients. Test results of thrombophilia-hypofibrinolysis were obtained in 153 patients with CVD ≤ age 45, 110 healthy normal controls, and 110 patients who had venous thromboembolism (VTE) without CVD. Of the 153 patients with CVD, 121 (79%) had sustained myocardial infarction, 70 (46%) had coronary artery stenting, and 53 (35%) had coronary artery bypass grafts. The first CVD events occurred at ages >20 to 35 in 47 patients and at ages >35 to 45 in 106 patients...
