A nested case–control study of risk for pulmonary embolism in the general trauma population using nationwide trauma registry data in Japan

Post-trauma patients are at great risk of pulmonary embolism (PE), however, data assessing specific risk factors for post-traumatic PE are scarce. This was a nested case–control study using the Japan Trauma Data Bank between 2004 and 2017. We enrolled patients aged ≥ 16 years, Injury Severity Score ≥ 9, and length of hospital stay ≥ 2 days, with PE and without PE, using propensity score matching. We conducted logistic regression analyses to examine risk factors for PE. We included 719 patients with PE and 3595 patients without PE. Of these patients, 1864 [43.2%] were male, and their median Interquartile Range (IQR) age was 73 [55–84] years. The major mechanism of injury was blunt (4282 [99.3%]). Median [IQR] Injury Severity Score (ISS) was 10 [9–18]. In the multivariate analysis, the variables spinal injury [odds ratio (OR), 1.40 (1.03–1.89)]; long bone open fracture in upper extremity and lower extremity [OR, 1.51 (1.06–2.15) and OR, 3.69 (2.89–4.71), respectively]; central vein catheter [OR, 2.17 (1.44–3.27)]; and any surgery [OR, 4.48 (3.46–5.81)] were independently associated with PE. Spinal injury, long bone open fracture in extremities, central vein catheter placement, and any surgery were risk factors for post-traumatic PE. Prompt initiation of prophylaxis is needed for patients with such trauma.

Ultrasound evaluation of dialysis access-related distal ischaemia

Dialysis access-related distal ischaemia is a rare yet potentially rather risky complication of haemodialysis angioaccess. Timely diagnosis is crucial to target both the goals of the access team: first of all to preserve the function of the hand ideally along with angioaccess patency. Unfortunately for some patients, urgent access ligation and central vein catheter insertion would be needed to save the hand. After a first clinical examination to determine the diagnostic suspicion, the ultrasound evaluation would provide nearly all the needed information to confirm the diagnosis and to determine the most appropriate procedure to rescue the patient from distal ischaemia. In some cases, photoplethysmography would help in the differential diagnosis of other non-ischaemic causes of similar signs and symptoms. Angiography would complete the preoperative evaluation for some. Dialysis access-related distal ischaemia would be briefly reviewed, and a deep description of the ultrasound examination tools and findings would be provided for a tailored therapeutic approach.

Central vein Catheter Treatment (CVC) is the treatment of a hose that is used to provide liquids or medicines. Appliance is installed in a blood vessel near the heart. The primary infection of blood flow occurring within 48 hours after the installation of CVC The purpose of this research is to know the CVC treatment relationship in CVC attached patients to the primary blood flow infection in ICU RSUP. H. Adam Malik Medan. The study uses correlation and observation research methods. The population in this research is the entire patient who CVC has installed, as well as all the nurses who do the CVC treatment. Based on the data obtained by the patient as much as 76 people. Patients are inclusiveness if the patient is hospitalized in less than 24 hours, and drop out if the patient dies in the treatment before it is found signs of IADP,as well as patients who come out of Adam Malik, then there are 32 patients. Research instruments in the form of questionnaires according to IADP. Analysis of data used statistical tests test Chi-Square. The results of the majority of the study of a major vein catether treatment (CVC) were as much as 28 (87.5%), the majority of which did not occur as much as 27 people (84.4%). Statistical test results obtained by the value of p- value =0.000 (<0.05) can be concluded there is a central venous catether treatment Relationship (CVC) in patients attached CVC to the occurrence of primary blood flow infection).

Catheter Access Management for Acute Peritoneal Dialysis

Insertion of a peritoneal dialysis (PD) catheter is frequently done by interventional nephrologists, but these procedures are typically only performed for adults. Almost all invasive procedures in children are performed by pediatric surgeons. If a pediatric surgeon is unavailable, the initiation of PD in acute situations may be delayed, thus increasing the risk of complications and chronic kidney disease. For these patients, the main obstacle to initiating renal replacement therapy is access, even when involving central vein catheter (CVC) or peritoneal access. Here we report the case of a 10-kg baby affected by hemolytic and uremic syndrome diarrhea in whom all of the procedures to manage the complications of acute kidney injury (PD catheter insertion, PD catheter revision, CVC placement, and CVC revision) were undertaken by interventional nephrologists. This experience allowed us to rapidly treat the acute kidney injury, recover normal kidney function thereby avoiding chronic complications, and allowing us to discharge the baby from the intensive care unit.

Cubital vein transposition for a distal radiocephalic fistula complicated by outflow obstruction

Introduction: Outflow stenosis is a frequent complication of vascular access for hemodialysis. It may cause increased pressure within the angioaccess along with reduced blood flow. Elective treatment is percutaneous transluminal angioplasty; however, when a long occlusion (>2 cm) occurs, success and mid-term patency of endovascular treatment are uncertain. We describe a case series of patients with long occlusion of elbow outflow complicating an otherwise excellent forearm arteriovenous fistula, treated by a bypass across the elbow through cubital vein transposition. Patients and methods: Six consecutive patients have been treated between 2015 and 2017; all were referred because of either low flow, increased venous pressure, excessive bleeding time, or recirculation and were examined by duplex ultrasound. A total of 83% of patients showed associated thrombosis within the access. All procedures were performed under loco-regional anesthesia and preventive hemostasis. Surgical thrombectomy was also performed when needed. Results: Immediate success was obtained in all but two patients converted in veno-venous polytetrafluoroethylene bypass. Post-operative blood flow increased from 316 to 878 mL/min. All patients were dialyzed through the forearm access immediately the day after surgery, without the need for central vein catheter. Overall, 75% of patients needed a percutaneous transluminal angioplasty of the veno-venous anastomosis within 6 months. Primary and secondary patency at 12 and 24 months were 25%–0% and 100%–100%, respectively. Conclusion: Outflow reconstruction through the elbow bypass by cubital vein transposition is a valuable resource to rescue radiocephalic arteriovenous fistula complicated by outflow obstruction, avoiding the use of an interim central vein catheter. Endovascular treatment is vital to maintain functional patency in the mid- and long term.

Malposition of hemodialysis catheter into the hepatic veins

Permanent central vein catheter for hemodialysis is a choice for hemodialysis vascular access. Permanent dialysis catheters may be inserted through the jugular, subclavian and femoral veins. It may be inserted when the patient have short life expectancy or not suitable for fistula operation. There may be so many complications for example malposition, hemorrhage and pneumothorax while inserting central venous catheter. Here we present a 44 year old female hemodialysis patient with a malpositioned permanent hemodialysis catheter, catheter tip was found in hepatic vein after three months of insertion.

THE IMPACT OF IATROGENIC EMBOLISATION AND ENDOVASCULAR REMOVAL OF A FRACTURED CENTRAL VEIN CATHETER ON THE HEALTH RELATED QUALITY OF LIFE (HRQOL)

Iatrogenic embolisation of the right ventricle of the heart by a fragment of one of the most basic ICU devices, which has fractured and detached the central vein catheter, is rarely described in subject literature. Removing such an element from the heart is highly risky and requires the use of very modern techniques and equipment. The Atrieve Vascular Snare™ was employed in the described patient. Therefore, it is necessary to present this process and its effectiveness through an evaluation of the health related quality of life (HRQoL) associated with the perception of health status by those patients. This is a requirement in modern medicine. The main aim of this paper was to evaluate the HRQoL after this embolisation. A 67-year-old patient was referred to the Vascular Surgery Department with Endovascular Interventions Ward, John Paul II Hospital in Kraków, after the defragmenting of the central vein catheter and replacement to the right ventricle of the heart. An endovascular approach through the right common femoral vein (RCFV) under local anesthesia of the groin was chosen as the preferred method for removing the broken catheter fragment. The right ventricle of the heart was reached using a 18-30mm Atrieve Vascular Snare™. A structure consisting of three loops facilitated the quick grasp and removal of the catheter fragment at the first attempt through the RCFV. Despite the short time needed for the procedure, the patient experienced periprocedural ventricular fibrillation (VF) with the necessity of defibrillation. After one successful defibrillation attempt, sinus rhythm was restored. The post-operative course showed no complications whatsoever, and the patient was sent to the General Surgery Ward in order for a new Hickman catheter to be implemented and further parenteral nutrition treatment to be carried out. The endovascular technique with the use of Atrieve Vascular Snare™ is an effective method which was used in the case of our patient under local anesthesia. It provides for the fast, safe and convenient removal of a disrupted and dislocated catheter fragment. It allows one to improve the patient’s HRQoL not only in the short term, but also in the longitudinal (6 months after surgery) follow up.
