Post-traumatic lethal carotid-cavernous fistula.
2006
The authors report about an unexpected death by traumatic lesion of the internal carotid artery in a 30-year-old man who had fallen two metres. The man suffered a fracture of the left maxillary sinus and a fracture of the right orbit with bilateral haemorrhage of the maxillary sinus. Surgical treatment was performed with favorable outcome. Clinically, there were no neurological symptoms but about 60 days after his accident, the man died from uncontrolled epistaxis. He was submitted to the autopsy that show a linear fracture in the left side of the turcic sella and lesion of the left internal carotid artery with carotid-cavernous fistula.
Real-time ultrasound-guided infraclavicular axillary vein cannulation: A prospective study in mechanically ventilated critically ill patients.
2016
Purpose: The main purpose of this study was to define the venipuncture and catheterization success rates and early mechanical complication rates of ultrasound-guided infraclavicular axillary vein cannulation. Materials and methods: We performed in-plane, real-time, ultrasound-guided infraclavicular axillary vein catheterizations under emergency and nonemergency conditions in mechanically ventilated, critically ill patients. Results: We performed 202 cannulation attempts. One hundred and twenty-six procedures (62.4%) were performed under emergency conditions. The puncture of the axillary vein was successful in 98.5% of patients, and the entire procedure success rate was 95.1% (95% confidence…
Home parenteral nutrition-associated thromboembolic and bleeding events: results of a cohort study of 236 individuals
2016
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety …
The intravascular ultrasound morphometry of iliac veins in subjects without severe chronic venous insufficiency and its implications for treatment in…
2019
Objectives The purpose of this study is to report the intravascular ultrasound morphometry of iliac veins and its relation to demographic and anthropometric factors in subjects without chronic venous insufficiency. Methods Thirty-three patients, without chronic venous insufficiency – qualified to great saphenous vein stripping due to unilateral, primary varicose veins – participated in the study. During the surgery, left and right external iliac veins, common iliac veins and inferior vena cava were interrogated with intravascular ultrasound. The morphometric analysis included measurement of a cross-sectional area at normal, non-stenosed vein segments (ref-CSA) and at the point of the most p…
Clonal populations of hematopoietic cells with paroxysmal nocturnal hemoglobinuria phenotype in patients with splanchnic vein thrombosis
2014
Abstract Introduction Splanchnic vein thrombosis (SVT) is a serious complication in patients with paroxysmal nocturnal hemoglobinuria (PNH). Mutant PNH clones can be associated with an increased risk of SVT even in the absence of overt disease, but their prevalence in non-selected SVT patients remains unknown. Materials and Methods Patients with objective diagnosis of SVT and without known PNH were tested for the presence of PNH clone using high-sensitivity flow cytometric analysis. Results A total of 202 SVT patients were eligible, 58.4% were males, mean age was 54.6 years (range 17–94), site of thrombosis was portal in 103 patients, mesenteric in 67, splenic in 37, and supra-hepatic in 10…
The diagnostic performance of renal function-adjusted D-dimer testing in individuals suspected of having venous thromboembolism
2019
Renal impairment, a source of chronic hypercoagulability[1][1] and inflammation,[2][2] is known to reduce the specificity of the D-dimer test in the diagnosis of venous thromboembolism (VTE).[3][3] This leads to many false positives in such patients and consequently to additional costs, as well as
Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia
2002
background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…
Intra- and extracerebral blood flow changes and flushing after intravenous injection of human corticotropin-releasing hormone
1994
To study facial flush after systemic administration of human corticotropin-releasing hormone (hCRH) we injected 100 micrograms hCRH intravenously to ten healthy young men. The increase in facial temperature was measured by infrared camera. A significant increase in facial temperature of 1.39 degrees C +/- 0.3 was found within 7 min in all patients, which lasted up to 60 min, although facial flushing was visible in only 50% (5/10) of the probands. In a second experiment 100 micrograms hCRH was then administered to seven other healthy young men. Intra- and extracerebral blood flow velocity changes in the medial cerebral artery (MCA) and external carotid artery (ECA) were measured after hCRH a…
Venous thromboembolism after oral and maxillofacial oncologic surgery: Report and analysis of 14 cases in Chinese population.
2016
Background Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. Material and Methods The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. Results 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT,…
Validation of the STA-Liatest DDi assay for exclusion of proximal deep vein thrombosis according to the latest Clinical and Laboratory Standards Inst…
2018
: Recommended strategy for venous thromboembolism (VTE) diagnosis includes the use of sensitive D-dimer (DDi) assays along with pretest probability (PTP) assessment. The Clinical and Laboratory Standards Institute (CLSI) recently issued a guideline (US FDA endorsed) on DDi in VTE exclusion. Such guideline specifies the ideal D-dimer assay characteristics and target population. Demonstrate STA-LiatestD-Di performance combined with a PTP score for proximal deep vein thrombosis (pDVT) exclusion in a CLSI compliant study. International, multicenter, prospective nonrandomized, noninterventional clinical outcome management study conducted in a standard-of-care setting. DDi was measured in DVT-sus…
