INTRODUCTION: The systemic inflammatory response has been proven to have a prognostic value. There are two methods of assessing the systemic inflammatory response composite ratios (R) and cumulative scores (S). The aim of this study was to compare the prognostic value of ratios and scores in patients undergoing surgery for colon cancer. METHODS: Patients were identified prospectively in a single surgical unit. Preoperative neutrophil (N), lymphocyte (L), monocyte (M) and platelet (P) counts, CRP (C) and albumin (A) levels were recorded...

A new surgical technique of intra-tumoural ligation for the treatment of low-flow vascular malformations in the head and neck region is proposed. Ninety patients with diffuse low-flow vascular malformations diagnosed clinically and/or radiologically were treated surgically with the corset suturing technique. All patient records and clinical photographs were reviewed retrospectively. Significant clinical results were obtained: a reduction of the turnout tumour mass and a return of the regional facial outline was evident within 4 weeks after surgery...

BACKGROUND:  In microvascular surgery, patients often receive unfractionated heparin infusions to minimize risk for microvascular thrombosis. Patients who receive intravenous (IV) heparin are believed to have adequate prophylaxis against venous thromboembolism (VTE). Whether a fixed dose of IV heparin provides detectable levels of anticoagulation, or whether the "one size fits all" approach provides adequate prophylaxis against VTE remains unknown. This study examined the pharmacodynamics of fixed-dose heparin infusions and the effects of real-time, anti-factor Xa (aFXa) level driven heparin dose adjustments...

The posterior third ventricle and pineal region can harbor different pathologies. The supracerebellar infratentorial approach allows a direct access to the pineal region and posterior third ventricle and provides wide exposure of the arachnoid planes and deep venous system. In this 3-dimensional video, we present a patient with posterior third ventricular/pineal region tumor who underwent microsurgical resection via supracerebellar infratentorial approach. The patient is a 28-year-old woman with history of hydrocephalus who underwent endoscopic third ventriculostomy and biopsy at an outside hospital...

A 59-yr-old man presented with intraventricular hemorrhage and was found to have a large temporo-occipital arteriovenous malformation (AVM), Spetzler-Martin grade 4. The preoperative intra-arterial digital subtraction angiography (IADSA) showed the AVM was 4 × 4 cm2, had superficial and deep venous drainage, and was fed by multiple branches of the posterior cerebral artery and middle cerebral artery. Preoperative embolization was done in 4 stages. He underwent a left temporo-occipital craniotomy, mastoidectomy, and retrosigmoid craniotomy with a posterior temporal approach...

Selecting appropriate patient position for surgery must take into consideration a variety of factors. For an interhemispheric approach to distal anterior cerebral artery (DACA) aneurysms, the patient may be positioned with the head either horizontal or vertical with respect to the floor. We preferentially place the patient in the supine position with the shoulder elevated and the head turned parallel to the floor with the side of the approach down and the vertex tilted 45° up. In this way, gravity is utilized to allow the right frontal lobe to fall away from the falx, eliminating the need for retraction...

Although sublobar resection (SLR) for treating non-small cell lung carcinoma (NSCLC) is still controversial, thoracoscopic segmentectomy is rising. Performing it by closed chest surgery is complex as it means confirming the location of the lesion, identifying vascular and bronchial structures, preserving venous drainage of adjacent segments, severing the intersegmental plane and ensuring an oncological safety margin with no manual palpation and different landmarks. Accurate planning is mandatory. We discuss in this article the interest of 3D reconstruction and mapping technics to enhance safety and reliability of these procedures...

INTRO: Venous thromboembolism (VTE) is a rare event in children, but can cause significant morbidity and mortality. The majority of research on pediatric VTE has been in the trauma and critical care populations. The incidence of VTE after surgery in children is not well-established. OBJECTIVE: The objective was to evaluate the incidence of VTE in the 30 days after surgery, as well as associated risk factors. STUDY DESIGN: All cases in the National Surgical Quality Improvement Program Pediatric (NSQIPP) database from 2012 to 2015 were assessed for presence of post-operative VTE...

Thromboses of the superior and inferior vena cava, either isolated or associated with distal deep venous thrombosis, are uncommon, but confer potentially serious morbidity and mortality. Incidence is increasing, especially with the prominence of intravascular devices. The range of treatment options is also expanding to include medical management, surgery, and endovascular techniques which are now frequently considered first line therapy due to lower reintervention rates and decreased periprocedural morbidity...

Venous malformations are the most common type of congenital vascular malformation. The diagnosis and management of venous malformations may be challenging, as venous malformations may be located anywhere in the body and range from small and superficial to large and extensive lesions. There are many treatment options for venous malformations including systemic targeted drugs, open surgery, sclerotherapy, cryoablation, and laser photocoagulation. This article reviews the natural history, clinical evaluation, imaging diagnosis, and treatment modalities of venous malformations...

Endovascular techniques have revolutionized the management of deep venous occlusive disease. Open surgery, however, is still required for cases that prove refractory to endovascular interventions. The surgical management of deep venous occlusive disease typically involves venous bypass. Preoperative planning before open venous surgery relies upon dynamic imaging to clarify the location and severity of venous obstruction, the assessment of infrainguinal reflux, and the delineation of bypass origination and target vessels...

NSAID analgesics may confound models that require inflammation to mimic disease development in humans. This effect presents a challenge for veterinary staff and investigators, because surgery is often necessary to create mouse models of disease and NSAID are first-line analgesics used to treat postoperative pain. We evaluated robenacoxib, a NSAID highly selective for cyclooxygenase 2, in a carrageenan paw edema (CPE) assay and surgical model of venous thrombosis (VT). We generated a mouse-specific dose-response curve by using the CPE assay for robenacoxib doses of 3...

BACKGROUND: Dexmedetomidine (DEX) is an α-2 adrenergic agonist with sedative and analgesic properties. Although not approved for pediatric use by the Food and Drug Administration, DEX is increasingly used in pediatric anesthesia and critical care. However, very limited information is available regarding the pharmacokinetics of DEX in children. The aim of this study was to investigate DEX pharmacokinetics and pharmacodynamics (PK-PD) in Mexican children 2-18 years of age who were undergoing outpatient surgical procedures...

AIM: Formation of autogenous arteriovenous fistula (AVF) in patients with chronic kidney disease (CKD) is complicated by a high primary failure rate due to pre-existing vascular damage. We hypothesized that Venous Preservation Scan (VPS) - early (months to years before AVF creation) vascular mapping followed by vasculature preservation is effective in protecting the patient's best "for fistula" vasculature. This study was performed to evaluate the impact of VPS on AVF outcomes...

Venous thromboembolism (VTE) is a serious complication during and after hospitalization, yet is a preventable cause of in-hospital death.Without VTE prophylaxis, the overall VTE incidence in medical and general surgery hospitalized patients is in the range of 10% to 40%, while it ranges up to 40% to 60% in major orthopaedic surgery. With routine VTE prophylaxis, fatal pulmonary embolism is uncommon in orthopaedic patients and the rates of symptomatic VTE within three months are in the range of 1.3% to 10%.VTE prophylaxis methods are divided into mechanical and pharmacological...

Background: Low-molecular-weight heparin (LMWH) is a recommended anticoagulant for thromboprophylaxis after major orthopedic surgery. Dabigatran etexilate is an oral anticoagulant recognized as noninferior to LMWH. We aimed to assess the incidence of symptomatic venous thromboembolic events (VTEs) after discharge in patients who underwent joint replacement, using a hospital registry. Patients and methods: Patients who underwent total knee and hip arthroplasty between September 2011 and March 2015 were selected...

We encountered a case of retroaortic left renal vein (RLRV) during an anatomical dissection course at our medical school in 2017. The case was a female cadaver who was 88 years old at death. Six roots of the left renal vein (RV) arose from the hilus of the kidney and joined to form one left renal vein, crossed dorsal to the abdominal aorta (AA) at the level of the second lumbar vertebra, and then drained into the inferior vena cava (IVC). Two roots joined at the right renal hilus to become the right RV to then drain into the IVC at the level of the first lumbar vertebral body...

May-Thurner syndrome (MTS) is a rare condition in which patients develop iliofemoral deep venous thrombosis owing to an anatomic variant in which the right common iliac artery overlies and compresses the left common iliac vein against the lumbar spine. Data regarding lower extremity trauma in patients with previously diagnosed MTS are rare. We discuss the operative approach for ankle trauma occurring 3 weeks after endovascular surgery for the treatment of MTS.
