BACKGROUND: Venous thromboembolism is one of the general complications following total hip arthroplasty, wherein various preventive treatments have been recommended. Several studies reported that venous thromboembolism incidence after total hip arthroplasty was similar in patients who were administered prophylaxis with a conventional mechanical procedure alone, and those who were administered pharmacological anticoagulation therapy. Therefore, the optimum methods of prophylaxis are still controversial...

To perform accurate hepatectomy without injury, it is necessary to understand the anatomical relationship among the branches of Glisson's sheath, hepatic veins, and tumor. In Japan, three-dimensional (3D) preoperative simulation for liver surgery is becoming increasingly common, and liver 3D modeling and 3D hepatectomy simulation by 3D analysis software for liver surgery have been covered by universal healthcare insurance since 2012. Herein, we review the history of virtual hepatectomy using computer-aided surgery (CAS) and our research to date, and we discuss the future prospects of CAS...

OBJECTIVE: Given its rarity, the management of primary upper extremity deep vein thrombosis is controversial. Although anticoagulation alone is commonly advocated for its treatment, it is unclear if this will reduce the risk of developing post-thrombotic syndrome (PTS). The aim of this "Evidence Driven" Clinical Scenario is to evaluate whether more aggressive treatments (including catheter directed thrombolysis or surgery) might help reduce the risk of PTS or recurrent venous thromboembolism in patients with primary upper extremity deep vein thrombosis (DVT)...

BACKGROUND: The Organ Procurement Network recommends a surgeon record 15 cases as surgeon or assistant for laparoscopic donor nephrectomies (LDN) prior to independent practice. The literature suggests that the learning curve for improved perioperative and patient outcomes is closer to 35 cases. In this article, we describe our development of a model utilizing fresh tissue and objective, quantifiable endpoints to document surgical progress and efficiency in each of the major steps involved in LDN...

BACKGROUND: Pancreaticoduodenectomy (PD) is the standard surgical procedure for treating pancreatic head cancers. Considerable knowledge of proximal jejunal and pancreatic vein anatomy is a prerequisite for performing PD surgery safely, yet there appear to be no detailed descriptions of first and second jejunal vein (J1V, J2V) anatomy available in the literature. STUDY DESIGN: Adults with hepatobiliary-pancreatic disease underwent multidetector-row computed tomography with intravenous contrast (n=155), and SYNAPSE 3D(®) (Fujifilm Medical, Tokyo, Japan) was used to generate 3D-CT images...

Live donors should be the priority of transplant professionals to prevent surgery-related morbidity and mortality during living-donor liver transplantation. Portal vein thrombosis after donor hepatectomy is an important complication which can be prevented by careful preoperative as well as perioperative evaluation. If portal vein thrombus occurs after donor hepatectomy, anticoagulation and surgical thrombectomy and even portal vein reconstruction should be kept in mind. Cadaveric venous patches can be used for the reconstruction of narrowed and angulated portal veins...

Transplant renal vein thrombosis usually occurs early after surgery with a reported prevalence of 0.1% to 4.2%. It is a devastating event that ultimately leads to graft loss in almost all cases. There are many predisposing factors related to donor, recipient, surgery, and immunosuppression, with mechanical factors being considered the most common causes of transplant renal vein thrombosis. The clinical manifestations of acute renal vein thrombosis are nonspecific and are not dissimilar to the features of urine leak, urinary obstruction, or severe acute rejection...

In most patients with superficial siderosis of the CNS, the exact source of bleeding remains unknown because of a lack of objective surgical data. The authors herein describe the case of a 58-year-old man with superficial siderosis of the CNS. The patient also had spinal CSF leakage due to a spinal dural defect. Repair surgery for the dural defect was performed using posterior laminoplasty with a transdural approach without spinal fixation. During repair surgery, the bleeding source was found to be the epidural vein around the defect...

Patients undergoing orthopedic surgery have an increased risk for deep venous thrombosis (DVT) and pulmonary embolism (PE). These complications are considered detrimental, as they cause major postoperative morbidity and mortality and lead to a substantial health care burden. Because of the high incidence and serious nature of these complications, it is essential for orthopedic surgeons to have a comprehensive knowledge of the risk factors, diagnosis, and treatment of acute DVT and PE. Perioperative management of orthopedic patients to prevent postoperative DVT and PE and optimize postoperative outcomes is also discussed in this review...

BACKGROUND: There are few studies that have determined clinical outcomes following inferior vena cava filter (IVCF) insertion in cancer patients hospitalized for acute deep-vein-thrombosis (DVT) or pulmonary embolism (PE). METHODS AND RESULTS: We analyzed hospital discharge records of all patients with active cancer who were admitted to a California hospital specifically for acute DVT or PE between 2005 through 2009. Propensity and competing risk methodology were used to determine if IVCF-use lowered either 30-day mortality or the risk of recurrent PE, DVT, and major bleeding within 180days...

Aortic graft infection is one of the most serious complications of aortovascular surgery. Diagnosis is based on clini-cal and radiologic findings. The emphasis is put on early diagnosis and its impact on prognosis of patients. The management should be individualized. The gold standard is surgical treatment with complete excision of the infected foreign material with debridement of the surrounding tissue and repair of vascular continuity by extra-anatomic bypass or in situ bypass with autologous femoral vein or cryopreserved arterial allografts...

BACKGROUND: Ischemia-reperfusion (I/R) injury is a common cause of patient morbidity and mortality in the perioperative period. Patients undergoing long-lasting, abdominal, and urogenital surgeries with risk factors such as advanced age, peripheral artery disease, diabetes mellitus, renovascular disease, and congestive heart failure are candidates for acute kidney injury (AKI) due to impaired renal perfusion and decreased functional renal reserve. Pharmacological agents with multiple functions and anti-oxidative and anti-inflammation properties may be promising preventative strategies for AKI...

Laparoscopic surgical approaches, compared with open surgical approaches, provide comparable clinical outcomes, but lower complications. Unfortunately, a rare complication-portomesenteric vein thrombosis-had been reported after laparoscopic surgery. A 42-year-old woman was referred our hospital for recurrent abdominal pain after laparoscopic appendectomy from acute appendicitis. It was determined that abdominal pain was due to postoperative superior mesenteric vein thrombus. A six-month anticoagulation therapy is an excellent treatment for superior mesenteric vein thrombus ...

The Lymphatic Microsurgical Preventing Healing Approach (LYMPHA) procedure entails performing a lymphovenous bypass (LVB) at the time of axillary lymph node dissection to reduce lymphedema risk. The two most common fluorophores utilized in LVB are blue dye and indocyanine green. We developed a novel application of fluorescein isothiocyanate for intraoperative lymphatic mapping. Our goal is to demonstrate the safety and efficacy of fluorescein isothiocyanate for this application. We reviewed a prospectively collected database on breast cancer patients who underwent LYMPHA from March to September 2015...

The creation of an arteriovenous fistula (AVF) is a common surgical procedure in hemodialysis patients suffering from end-stage renal disease (ESRD). However, several complications may occur after surgery, including thrombosis, stenosis, and aneurysm. These complications are attributed to hemodynamics perturbations including pathophysiological wall shear stress (WSS) and flow recirculation zones. In this study, we present a computational hemodynamic analysis in a model of a mature side-to-side AVF, which is then validated by experimental measurements...

A 62-year-old man with situs inversus totalis and non-small-cell lung cancer underwent a right lower lobectomy by video-assisted thoracoscopic surgery. Lobectomy in a situs inversus totalis patient can be performed safely using this minimally invasive procedure. Preoperative evaluation of the pulmonary artery and veins by three-dimensional computed tomography and the bronchial tree by bronchoscopy, is essential to avoid unanticipated complications during the procedure.

Postsurgical deep brain venous thrombosis has not been well described in children before. When approaching thalamic or intraventricular lesions, extra care should be taken to prevent injury to the internal cerebral veins (ICVs) and the vein of Galen. However, even when they are well preserved during surgery, postoperative hemodynamic changes, mainly in the first 24 h, or surgical manipulation can cause thrombosis of these veins. We report 2 children with unilateral postoperative ICV thrombosis; in 1 of the patients the vein of Galen was also thrombosed...
