Sprematic vein abscess after varicocele embolization - A case presentation.

Testicular varicocele is a dilatation of the pampiniform plexus. It is a common clinical problem affecting 15% of adolescents and adults that may be associated with pain and discomfort, and can affect fertility. Varicocele treatment is associated with a significant improvement in sperm parameters, and pregnancy rate.

Pediatric sedation in vascular malformations interventions by a non-anesthesiologist-feasibility and safety.

Objective: Sedation for pediatric patients undergoing interventional procedures in radiology is in increasing demand. Once only anesthesiology-performed, there is a demand for sedation services to perform sedations for these procedures. However, the safety of performing long sedations by non-anesthesiologists in interventional radiology has not been reported.

Hepatitis C virus cures after direct acting antiviral-related drug-induced liver injury: Case report.

The United States Food and Drug Administration recently warned that the direct acting antiviral (DAA) combination hepatitis C virus (HCV) treatment of Paritaprevir, Ombitasvir, Dasabuvir, Ritonavir, and Ribavirin (PODr + R) can cause severe liver injury in patients with advanced liver disease. Drug induced liver injury was observed in a small number of patients with decompensated cirrhosis treated with other DAAs, but has not been reported in patients with compensated cirrhosis. We report a case of a 74-year-old woman with chronic HCV and Child-Pugh class A cirrhosis (compensated cirrhosis) treated with PODr + R.

[Bile lake post Kasai hepatoportoenterostomy in biliary atresia].

In this case report we describe a boy with extrahepatic biliary atresia who underwent a Kasai hepatoportoenterostomy at six weeks of age. Beginning several weeks post-op, he had recurrent cholangitis inadequately controlled by various antibiotic prophylaxis regimens. Imaging revealed the development of several bile lakes in the liver hilum.

A prospective randomized study of heparin-bonded graft (Propaten) versus standard graft in prosthetic arteriovenous access.

Objective: Prosthetic grafts continue to be required for hemodialysis access when the options for native fistulas have been exhausted. The inferior long-term patency of grafts makes the possibility of preventing occlusion with heparin-bonded grafts an attractive alternative. We carried out a prospective randomized study to compare the patency of standard grafts with heparin-bonded grafts.

Upper limb grafts for hemodialysis access.

Arteriovenous (AV) grafts are required for hemodialysis access when options for native fistulas have been fully exhausted, where they continue to play an important role in hemodialysis patients, offering a better alternative to central vein catheters. When planning autogenous accesses using Doppler ultrasound, adequate arterial inflow and venous outflow must be consciously preserved for future access creation with grafts. Efforts to improve graft patency include changing graft configuration, graft biology and hemodynamics.

Radiation dose reduction in fluoroscopic procedures: left varicocele embolization as a model.

Objectives: To investigate the effect of a radiation reduction program on total dose, fluoroscopy dose per second corrected for body habitus and degree of collimation in left varicocele embolizations (LVE).

Methods: A radiation reduction program for LVE was implemented, consisting of a technique minimizing fluoroscopy time, using low-dose presets, virtual collimation, and virtual patient positioning. Height, weight, fluoroscopy time, kerma area product (KAP) and reference air kerma (Ka,r) were recorded for 100 consecutive cases satisfying the inclusion criteria.

Stent grafts for central venous occlusive disease in patients with ipsilateral hemodialysis access.

Purpose: To assess long-term outcomes of stent grafts in patients with symptomatic central venous stenoses and occlusions ipsilateral to hemodialysis grafts or fistulas.

Materials And Methods: The study included 52 of 55 consecutive patients with symptomatic stenoses of the central veins draining upper limb dialysis access grafts or fistulas treated with stent grafts. Indications for stent grafts were poor angioplasty results, rapid recurrence, or total occlusion.

Stent graft treatment for hemodialysis access aneurysms.

Background: Aneurysms that develop in arteriovenous accesses as a result of repeated punctures are sometimes complicated by infection or ischemia causing sloughing of the overlying skin, which may endanger the access and risk major bleeding and other complications. Surgical revision may necessitate the temporary use of a central venous catheter until dialysis can be resumed via the access. We used stent grafts in selected patients for the exclusion of access aneurysms.

Indwelling central venous access port insertion during bevacizumab-based therapy.

Indwelling central venous catheters and implantable port systems are widely used in the care of patients with cancer. Bevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor, significantly prolongs survival when added to intravenous 5-fluorouracil-based chemotherapy as first-line treatment for metastatic colorectal cancer. It has also been shown to be of value in a range of other malignant diseases.

Percutaneous "stepped" drainage technique for infected pancreatic necrosis.

Introduction: Aggressive surgical pancreatic debridement remains the standard of care, may require multiple abdominal explorations and is associated with high mortality. We have introduced the stepped technique of percutaneous treatment of infected peripancreatic fluid collections.

Methods: We performed a retrospective review of patients with severe infected necrotizing pancreatitis who were managed percutaneously.

Urgent endovascular stent-graft placement for traumatic penetrating subclavian artery injuries.

Penetrating injuries may infrequently cause pseudoaneurysms, lacerations and arteriovenous fistulas involving the subclavian artery. These injuries present with life-threatening bleedings, associated regional injuries and critical limb ischemia and although surgery has been considered the treatment of choice, subclavian injuries pose a real surgical challenge. We prospectively examined data of six patients presenting with penetrating subclavian artery injuries that were treated by urgent endovascular stent-graft placements.

Gastric arterio-venous malformation emerging from splenic artery.

In this case report, we present a patient who suffered from gastrointestinal bleeding. The bleeding source was a gastric arterio-venous malformation emerging from the splenic artery. Attempts to stop the bleeding failed and therapeutic angiography succeeded in occluding the vessel.

Endovascular treatment of ileocolic pseudoaneurysm after a laparoscopic-assisted bowel resection for Crohn disease.

Since the introduction of laparoscopic-assisted ileocolic resection for Crohn disease more than 15 years ago, it has become established as a challenging but feasible and safe procedure. A crucial step in the operation is the division of the thick and chronically inflamed mesentery, which in many cases is performed extracorporeally. We report a case of a 32-year-old man with a 14-year history of Crohn ileitis who underwent elective laparoscopic-assisted ileocolic resection.

Hemobilia due to hepatic artery aneurysm as the presenting sign of fibro-muscular dysplasia.

Fibro-muscular dysplasia (FMD) is a rare but well documented disease with multiple arterial aneurysms. The patients, usually women, present with various clinical manifestations according to the specific arteries that are affected. Typical findings are aneurysmatic dilatations of medium-sized arteries.

The use of 3D rendering, VCI-C, 3D power Doppler and B-flow in the evaluation of interstitial pregnancy with arteriovenous malformation treated by selective uterine artery embolization.

Cornual pregnancy is a rare form of ectopic pregnancy. We describe a case of cornual pregnancy suspected by two-dimensional ultrasonography (2DUS) and confirmed by three-dimensional volume contrast imaging in the C-plane. Three-dimensional power Doppler showed a particularly rich blood supply and two-dimensional color Doppler mapping demonstrated arteriovenous malformation (AVM).

Thrombocytosis accompanying urinary tract infection suggests obstruction or abscess.

Objective: Reactive thrombocytosis can be found in patients with different types of infections, including upper urinary tract infection (UTI). In this study, we determined whether thrombocytosis in patients with upper UTI is a random phenomenon or is related to complications associated with the UTI.

Methods: We reviewed the charts of patients admitted to the urology department with a diagnosis of upper UTI and thrombocytosis (platelet count >500 x 10(9)/L) in the years 1991 to 2003 (study group).

A cell-based multifactorial approach to angiogenesis.

We here propose an alternative cell therapy approach to induce angiogenesis. We prepared small organ fragments whose geometry allows preservation of the natural epithelial/mesenchymal interactions and ensures appropriate diffusion of nutrients and gases to all cells. Fragments derived from lung are shown to behave as fairly independent units, to undergo a marked upregulation of angiogenic factors and to continue to function for several weeks in vitro in serum-free media.

Arterial embolisation for persistent primary postpartum haemorrhage: before or after hysterectomy?

Arterial embolisation is a recognised treatment for postpartum haemorrhage (PPH). In this retrospective study, we evaluate its use in the management of persistent PPH. Records of all births during a 54 month period at a university hospital were analysed.

[Budd-Chiari syndrome: updated treatment modalities].

Budd-Chiari Syndrome (BCS) refers to hepatic venous outflow obstruction, resulting in simultaneous occurrence of hepatic congestion and portal hypertension, leading to a typical clinical triad consisting of right upper quadrant pain, hepatomegaly and ascites. Contrary to Asia and Africa, where BCS is caused primarily by an obstructing membranous web, BCS in the western world is considered a thrombotic complication of an underlying hypercoagulable state. Recognition of the contribution of hypercoagulability as a causative factor in BCS, has led to acknowledgement of the importance of anti-coagulant therapy in BCS.

Intrahepatic arterial administration of low-dose methotrexate in patients with severe hepatic graft-versus-host disease: an open-label, uncontrolled trial.

Background: Hepatic grafr-versus-host disease (GVHD) is associated with significant morbidity and mortality. Standard therapy includes systemically administered immunosuppressive drugs. More recent reports have described catheter-directed intrahepatic arterial (IHA) delivery of low-dose methotrexate (MTX) and methylprednisolone in the treatment of corticosteroid-resistant severe hepatic GVHD.

The incidence and causes of erectile dysfunction after pelvic fractures associated with posterior urethral disruption.

Purpose: Erectile dysfunction is a common sequel of pelvic fractures, particularly those associated with posterior urethral injury when it can be neurogenic or arteriogenic due to damage to the cavernous nerves or branches of the pudendal arteries. We studied erectile function of patients with posterior urethral injuries due to pelvic fractures.

Materials And Methods: Patients referred for posterior urethral reconstruction and strictures due to pelvic fractures were evaluated before reconstruction.

Shortening and migration of Wallstents after stenting of central venous stenoses in hemodialysis patients.

Purpose: To report our results for the placement of central venous stents in patients undergoing hemodialysis.

Methods: Ten Wallstents (Schneider, Bülach, Switzerland) were placed in 10 patients with shunt thrombosis, shunt dysfunction or arm swelling associated with central vein stenosis or occlusion. Technical success, patency and complications were evaluated.

[Local thrombolysis for the treatment of patients with proximal deep vein thrombosis of the leg].

Background: Standard anticoagulatn therapy for lower extremity DVT does not distinguish between proximal and distal veins. Catheter directed thrombolytic therapy is a new emerging aggressive option for suitable patients with proximal DVT.

Objectives: Review of the literature and presentation of two patients in whom the procedure was successfully performed.
