Accurate force simulation is essential to haptic simulators for surgical training. Factors such as tissue inhomogeneity pose unique challenges for simulating needle forces. To aid in the development of haptic needle insertion simulators, a handheld force sensing syringe was created to measure the motion and forces of needle insertions. Five needle insertions were performed into the neck of a cadaver using the force sensing syringe. Based on these measurements a piecewise exponential needle force characterization, was implemented into a haptic central venous catheterization (CVC) simulator...

Lateral bony decompression may offer several biomechanical advantages and has become a commonly used surgical approach. Preoperative imaging plays a key role in surgical planning by providing information about the locoregional anatomy. The marrow space of the greater wing of the sphenoid is a focal point of the decompression surgery based on the volume that it occupies. Several vessels pass through the sphenoid bone, but most are small caliber vessels. The authors describe a case of an uncommon anatomical variant of the cranial diploic venous system in which the anterior transverse diploic vessel traverses the marrow space of the sphenoid...

Complex cardiac anomalies are sometimes channeled toward Fontan palliation for various reasons. Nevertheless, anatomical repair after bidirectional cavopulmonary shunt may be another option with theoretical benefits. In this study, we report our experience with anatomical repair conversion in challenging patients who had been palliated with bidirectional cavopulmonary shunt. Retrospective review was conducted in patients who underwent anatomical repair conversion from prior bidirectional cavopulmonary shunt palliation between January 2008 and March 2016...

BACKGROUND: The role of cutaneous microvascular dysfunction is well known in the development of chronic venous disease. However, the effects of venous obstruction on microcirculation have not been well investigated. The aim of this study was to assess cutaneous microvascular function in patients with iliocaval venous obstruction (ICVO) before and after venous stent placement. METHODS: Endothelium-dependent and endothelium-independent vasodilator responses to iontophoretic administration of incremental doses of acetylcholine (ACh) and sodium nitroprusside (SNP) were evaluated using a laser Doppler scanner in the perimalleolar region in the supine and sitting positions in patients with ICVO (n = 11) and in healthy control subjects (n = 15)...

OBJECTIVE: Endovenous thermal ablation has become the primary modality of treatment for patients with venous insufficiency. Previous literature has provided reviews of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) that mostly focus on the great saphenous vein (GSV) and small saphenous vein (SSV). Data with an extended review including the anterior accessory saphenous vein (ASV) and perforator veins (PVs) have been limited. This study examines the treatment of venous insufficiency with RFA and EVLA of these multiple veins to identify clinical and demographic predictors of both the early success and thrombotic complications of endovenous thermal ablation...

BACKGROUND: Chronic venous disorders (CVDs) have been estimated to affect up to 20 million Americans. Despite this huge prevalence, the signs, symptoms, and treatment outcomes in patients 65 years of age and older are not well defined. Our goal was to determine the presentation and treatment outcomes in elderly patients compared with a cohort of patients younger than 65 years. METHODS: From January 2015 to December 2016, we retrospectively reviewed prospectively collected data from 38,750 patients with CVD from the Center for Vein Restoration's electronic medical record (NextGen Healthcare Information Systems, Irvine, Calif)...

M Papamichail, M Pizanias, N Heaton
Congenital portosystemic venous shunts are rare developmental anomalies resulting in diversion of portal flow to the systemic circulation and have been divided into extra- and intrahepatic shunts. They occur during liver and systemic venous vascular embryogenesis and are associated with other congenital abnormalities. They carry a higher risk of benign and malignant liver tumors and, if left untreated, can result in significant medical complications including systemic encephalopathy and pulmonary hypertension...

BACKGROUND Celiacomesenteric trunk (CMT) is a very rare anatomic finding in which the celiac artery and the superior mesenteric artery (SMA) originate from the abdominal aorta through a common trunk. Clinical associations with CMT include arterial aneurysm, thrombosis, and celiac artery compression. However, an association between CMT and abdominal venous congestion caused by left renal vein compression, or 'nutcracker phenomenon,' has not been previously reported. CASE REPORT A 91-year-old woman, who died from a cerebrovascular accident (CVA), underwent a cadaveric examination at our medical school...

Cardiac electrophysiology is an evolving specialty that has seen rapid advances in recent years. Concurrently, there has been much progress in the field of cardiac imaging. Electrophysiologists are increasingly requesting cross-sectional imaging in advance of many procedures. Pulmonary vein isolation and left atrial appendage (LAA) occlusion are now an established treatment options for atrial fibrillation. In patients undergoing pulmonary vein isolation, applications of computed tomography (CT) include evaluating the left atrial and pulmonary venous anatomy, excluding LAA thrombus and assessing for pulmonary vein stenosis...

Venous malformations are slow flow dysplastic lesions, constituted by a vascular nest without arterial or capillary connections, more or less independent of the normal venous anatomy and circulation. In certain cases a treatment is required for symptom relief or for natural complications management. The percutaneous sclerotherapy under ultrasound guidance is increasingly used as an effective and mini-invasive option, allowing obtaining very good results with minor side effects. Several substances have been used with different efficacy and side effects rate...

BACKGROUND: Little is known about the anatomy of the jejunal veins (JVs) flowing into the superior mesenteric vein (SMV), and whether they can be safely divided during pancreaticoduodenectomy. METHODS: Computed tomography was used to review the jejunal branches off the superior mesenteric artery (SMA) and into the SMV in 123 consecutive patients. The common trunk of the JVs (jejunal venous trunk, JVT) was classified as ventral or dorsal to the SMA. RESULTS: The first JVT involved multiple JVs in 108 (87...

Posterior condylar canal dural arteriovenous fistula (PCC dAVF) is a rare entity with only three cases having been reported so far in the English literature. We describe the clinical presentation, imaging, and endovascular management of an elderly man with left PCC dAVF presenting with subarachnoid haemorrhage (SAH). Endovascular management of such cases requires thorough understanding of the vascular anatomy around the craniovertebral junction (CVJ) and variable bridging vein draining patterns. The fistula in our case was fed by the posterior meningeal branch of the left vertebral artery and was draining through a dilated and tortuous medullary bridging vein into the antero-lateral pontomedullary venous system...

INTRODUCTION: Although outcomes of liver transplantation (LT) have improved as the result of progress in surgical procedures, a failure to restore sufficient graft outflow may yield fatal consequences including graft dysfunction and even graft loss to date. In particular, patients with pre-existing obliterated venous drainage, such as those with Budd-Chiari syndrome (BCS), are at high risk of having venous complications followed by conventional LT. In selected cases, the transplant surgeons are compelled to modify the surgical procedures of LT from the conventional procedure...

Total anomalous pulmonary venous drainage (TAPVD) is an uncommon cardiac defect in children. The mixed subset accounts for 5%-10% of the TAPVD and is variable in its anatomy. The outcomes associated with this subset of patients are rarely reported. A retrospective review of all patients with mixed TAPVD undergoing repair at a single institution (1984-2014) was conducted. A descriptive analysis was performed. Twenty-four patients underwent repair for mixed TAPVD (6 univentricular physiology, 18 biventricular physiology)...

The location of burr holes in posterolateral cranial base approaches should be appropriate to provide an adequate operative field, and surgical freedom is crucial for bone window opening. The aim of this study was to search for more convenient and easily detectable landmarks in comparison with current landmarks in posterolateral cranial base surgery. Twenty 3-dimensional reconstructed head and neck computed tomography angiography images (group 1) and 20 cadaver heads (group 2) were evaluated. An imaginary line connecting the angle of the mandible and the mastoid tip was extended upward...
