BACKGROUND: Good results have been reported for angioplasty and stenting of post-thrombotic lesions of the iliac and proximal femoral veins. If lesions at the origin of the superficial femoral and profunda veins are stented, the intraluminal synechiae can be pushed against the orifices of inflow vessels, potentially decreasing stent inflow. Surgical disobliteration of the common femoral vein (endophlebectomy) has been suggested to mitigate this problem. Because of a temporary increase in thrombogenicity, this procedure may be accompanied by arteriovenous fistula creation...

OBJECTIVE: Hybrid operative thrombectomy (HOT) is a novel technique for the treatment of acute iliofemoral deep venous thrombosis (IFDVT) and is an alternative to percutaneous techniques (PTs) that use thrombolytics. In this study, we compare perioperative and intermediate outcomes of HOT vs PT as interventions for early thrombus removal. METHODS: From July 2008 to May 2015, there were 71 consecutive patients who were treated with either PT (n = 31) or HOT (n = 40) for acute or subacute single-limb IFDVT...

BACKGROUND: Platelet activation is crucial in the development of stent thrombosis following percutaneous coronary intervention (PCI). We carried out a long-term assessment of multiple factors implicated in the thrombotic process and markers of platelet activation, after implantation of sirolimus-eluting stents (SES) in patients with stable coronary artery disease (CAD), and we compared the results with those after bare-metal stent (BMS) implantation. METHODS: Forty-seven consecutive patients, aged <70 years, with severe stenosis (>70% narrowing of the lumen) of one major epicardial coronary artery and stable CAD, underwent successful elective PCI and were randomly allocated to SES (n=25) or BMS (n=22)...

The portacath is commonly used in the treatment of oncology patients. Although common long-term complications of these devices, such as infection and thrombosis, have been widely reported, venous-airway fistula due to port placement is an extremely rare and poorly understood complication. We report a case of a 56-year-old female with pancreatic adenocarcinoma whose portacath was complicated by the development of an azygo-bronchial fistula with a concomitant aspergilloma. Herein is the first reported case of successful venous-airway fistula closure obtained through silicone stenting...

Endovascular venous stenting is increasingly performed for a variety of conditions. Inferior vena cava stent migration has been reported up to 6 months after placement; stent migration 6 months after implantation is uncommon. To our knowledge, this is only the second reported case of late stent migration with valve entrapment 1.

Superior vena cava syndrome (SVCS) is secondary to obstruction of venous flow from the superior vena cava to the right atrium. Endovascular stenting is particularly useful when severe or rapidly progressive disease requires urgent treatment. In suspected mediastinal malignancy, transcaval biopsy can be combined with endovenous stenting to provide diagnosis and treatment in a single procedure. Three patients were referred for investigation and treatment of SVCS over a 20 month period. Under fluoroscopic guidance Cook Medical transjugular biopsy sets (with 20-gauge QuickCore biopsy needles) were used and two or three core biopsy samples were obtained...

BACKGROUND: Although vein stenting is popular for treatment for venous thromboembolism due to mechanical compression, some cases are forced to avoid inserting align agents because of immunodeficiency. CASE PRESENTATION: An 82-year-old man with left extremity redness and swelling presented to a hospital for a medical evaluation. The patient was immunodeficient because of the adverse effects of his treatment for Castleman's disease. A contrast-enhanced computed tomography scan revealed a venous thromboembolism in inferior vena cava and the left lower extremity...

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 x 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC was performed by partial resection of the aneurysm sac...

Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses...

Patients with critical limb ischemia have a poor life expectancy, and aggressive revascularization is accepted to maintain their independence in the end stage of life. Bypass surgery and, more recently, endovascular interventions with angioplasty and stenting have become the treatment of choice to prevent amputation and resolve rest pain. Up to 20% of patients with critical limb ischemia are not suitable candidates for a vascular intervention because of extensive occlusions of the outflow in the crural and pedal vessels...

Since obesity has become an epidemic in industrialized nations, idiopathic intracranial hypertension (IIH) is now a more common neuro-ophthalmic disorder that causes visual loss and headaches. This review highlights the new diagnostic criteria for IIH and the new insights into the pathophysiologic mechanisms of IIH. Key diagnostic and monitoring techniques for papilledema include not only neuroimaging and the measurement of cerebrospinal fluid (CSF) pressure, but also perimetry, optical coherence tomography, and ocular sonography...

Implantation of mammalian target of rapamycin (mTOR)-inhibitor drug-eluting stents (DESs) impairs coronary endothelial function. There are no known non-invasive biomarkers of coronary endothelial dysfunction. We aimed to assess the association between serum interleukin-1beta (IL-1β) and coronary endothelial dysfunction in patients with mTOR-inhibitor DES implantation and to investigate the association between the mTOR pathway and IL-1β. We enrolled 35 patients who had implanted DESs for coronary artery disease...

Superior vena cava syndrome is a well-known disease entity that carries substantial rates of morbidity and mortality. Although most cases of superior vena cava syndrome are secondary to a malignant process, additional causes (such as mediastinal fibrosis, pacemaker lead implantation, or central venous catheter placement) have been reported. Multiple treatment options include percutaneous transluminal angioplasty, stent implantation, thrombolysis, mechanical thrombectomy, and venous grafting. We present a case of superior vena cava syndrome in a symptomatic 30-year-old woman who obtained complete relief of obstruction and marked symptomatic improvement through venoplasty and stenting, aided by our use of a balloon-in-balloon catheter system...

BACKGROUND: Venous sinus stenting is an emerging treatment for patients with idiopathic intracranial hypertension and evidence of venous stenosis. Stents placed across the transverse and sigmoid sinuses often cover the vein of Labbé (VOL), a major anastomotic vein draining the cerebral hemisphere. The patency of the VOL after stenting and its clinical implications are poorly understood. METHODS: A retrospective analysis was performed of a prospectively collected database of patients undergoing venous sinus stenting...

BACKGROUND: In-stent restenosis occurs in 10-30% of patients following bare metal stent (BMS) implantation and has various risk factors. Mannose-binding lectin (MBL) is known to have effect on the progression of atherosclerosis. Single nucleotide polymorphisms (SNP) of the MBL2 gene intron 1 (codon 52, 54, 57) are known to modulate the bioavailability of the MBL protein. Our aim was to identify the association of these polymorphisms of the MBL gene in the occurrence of in-stent restenosis after coronary artery bare metal stent implantation...
