BACKGROUND: The current literature is controversial regarding the importance of obese body mass index (BMI) classifications as a risk factor for pulmonary complications following outpatient surgery. The objective of the current investigation was to evaluate predictors of pulmonary outcomes following outpatient surgery and to assess the importance of BMI weight classifications in risk assessment. STUDY DESIGN: Patients with "outpatient" recorded as their inpatient/outpatient status in the 2012-2013 NSQIP database were included...

BACKGROUND: Acquired thrombotic thrombocytopenic purpura (aTTP) is a life-threatening autoimmune thrombotic microangiopathy. In spite of treatment with plasma exchange and immunosuppression, patients remain at risk for thrombotic complications, exacerbations and death. In the Phase II TITAN study, treatment with caplacizumab, an anti-vWF Nanobody(®) , was shown to reduce the time to confirmed platelet count normalization and exacerbations during treatment. OBJECTIVE: The clinical benefit of caplacizumab was further investigated in a post-hoc analysis of the incidence of major thromboembolic events and exacerbations during the study drug treatment period and TTP-related death during the study...

RATIONALE: Abdominal aortic aneurysms (AAAs) are mostly asymptomatic. If aortic aneurysms become symptomatic, complications include peripheral embolization, acute aortic occlusion, and aortic rupture. However, there are also unusual complications caused by aortic aneurysms. PATIENT CONCERNS: An 87-old male with dabigatran therapy presented with newly developed melena and acute renal failure. Radiological imaging revealed an AAA with thrombotic and calcified deposits which affected the renal arteries...

BACKGROUND: Cerebral venous air embolism (CVAE) is a severe clinical condition related to unfavoured outcome in patients with neurological impairment. CVAE may occur secondary to arterial or venous interventions. A rare mechanism of CVAE is retrograde embolism that is characterized by gas flow in a direction opposite to that of the normal blood flow. CASE REPORT: A 69-year-old female was admitted to our hospital with shortness of breath and abdominal pain. Abdominal computed tomography (CT) revealed intramural gas in the bowel and free gas in the mesenteric veins and portal vein...

BACKGROUND: A nonthrombotic pulmonary embolism is defined as embolization to the pulmonary circulation. It may be caused by microorganisms, foreign bodies, different cell types or gas in the pulmonary circulation. Nonthrombotic emboli may cause a severe inflammatory reaction, both in the systemic and pulmonary circulation, as well as in the lungs. Pulmonary hydatid cyst-induced embolization is a rare complication of heart or liver hydatid cysts. CASE REPORT: We describe the fatal case of a 15-year-old boy without any known prior illness who was admitted to the hospital after feeling unwell and dropping to the ground while playing ball...

Background Segmental arterial mediolysis (SAM) is an uncommon or underdiagnosed arteriopathy that presents with life-threatening hemorrhage. SAM can affect the intracranial, spinal, and visceral arteries, with reported cases of concomitant intracranial and visceral hemorrhage. Case description We present the case of a 61-year-old male with concurrent subarachnoid and intraperitoneal hemorrhage caused by simultaneously bleeding posterior spinal artery and splenic artery pseudoaneurysms. The posterior spinal artery pseudoaneurysms were treated with selective injection of polyvinyl alcohol particles into the posterior spinal artery, while the splenic artery pseudoaneurysm was treated with Gelfoam embolization...

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy...

BACKGROUND: The risk of venous thromboembolism (VTE) differs between men and women. Some risk factors seem to influence the presenting location of VTE. Sex-specific differences in presenting VTE location have not been studied extensively. METHODS: We analysed data from the MEGA case-control study and the Hokusai-VTE study, and used published data from the RIETE registry. Data from patients with a symptomatic first VTE were included (MEGA n=4953; Hokusai-VTE n=6720; RIETE n=40028)...

BACKGROUND: Studies on the risk of recurrent venous thrombosis in patients with excess body weight have yielded conflicting results. OBJECTIVE: To estimate whether excess body weight increases the risk of recurrent venous thrombosis. PATIENTS/METHODS: We included 3 889 patients, followed after a first venous thrombosis for a median of 5.6 years. Body mass index (BMI) was calculated as weight in kilograms/height in meters squared, and classified according to three a-priori defined categories (normal weight/overweight/obesity), as well as by percentiles...

BACKGROUND: A few studies focused on the risk of recurrence after first acute isolated distal deep vein thrombosis (IDDVT) compared to proximal DVT (PDVT), while the incremental risk of death has never been explored beyond the first three years after acute event. METHODS: Our single-center cohort study included patients with first symptomatic acute PDVT or IDDVT. Patients were excluded if they had concomitant pulmonary embolism (PE) or prior venous thromboembolism...

BACKGROUND: Patients with hematologic malignancies are at high risk for both thrombosis and bleeding. During the prolonged periods of thrombocytopenia experienced by patients who are receiving intensive chemotherapy, clinicians often hesitate to prescribe any protection against thrombosis. In case of anticoagulant prescription, it is the prescribers' responsibility to weigh risks and benefits for each patient. Current guidelines exist but do not take into account types of thrombosis, patients' comorbidities, or previous bleeding events...

Adriane Mayer, Philipp Schuster, Bernd Fink
INTRODUCTION: Patients who have undergone hip or knee replacement surgery are exposed to a high risk of developing a post-operative venous thromboembolus and so have a need for an effective, medication-based, thrombosis prophylaxis. New orally active anticoagulants have been available for a few years now. These specific substances directly block either thrombin (e.g., dabigatran etexilate) or Factor Xa (e.g., apixaban). It is not clear whether there are any efficacy differences between these two substances because there have never been any head-to-head studies carried out...

Due to the complex anatomy of the anterior skull base and paranasal sinuses, radiologic diagnostics in this area are challenging. Magnetic resonance imaging (MRI) and computed tomography (CT) are the primary indicated modalities. Guidelines helping to select the appropriate modality have been published by the German Society of Head and Neck Radiology and the Society of Otorhinolaryngology. The present article presents an overview of the current radiologic procedures and their optimized implementation using clinical examples...
