Development of Rhabdomyolysis in the Long-term Period of Previous New Coronavirus Infection COVID-19 (Clinical Case Report)

Relevance. Rhabdomyolysis is one of the complications of the new coronavirus infection COVID-19, which may cause acute kidney injury (AKI). The reason for the development of rhabdomyolysis in our observation in a patient after suffering COVID-19 in the long-term period was an increased muscle load.Aim of study. Presentation of a case of rhabdomyolysis with AKI in a patient after COVID-19 in the long-term period.Material and methods. In clinical observation, a 25-year-old patient L. is presented, who was being treated in the Department for the Treatment of Acute Endotoxicosis of the N.V. Sklifosovsky Research Institute for Emergency Medicine. In 2020, he developed COVID-19, complicated by rhabdomyolysis and AKI in the long term period.Results. Examination revealed an increase in creatinine phosphokinase (CPK) — 106,000.0 U/L, alanine aminotransferase (ALT) — 553.0 U/L, aspartate aminotransferase (AST) — 1582.0 U/L, lactate dehydrogenase (LDH) — 2809.0 U/L, levels of serum creatinine 164 μmol/L and myoglobin — 201 ng/ml. Virological research: IgM — 0.27 units per ml; IgG — 7.28 units per ml. 3 Three-phase scintigraphy with 99mTc-pyrfotech revealed signs of necrotic changes in the muscles of the upper half of the back, muscles of the chest (mainly on the right), muscles of the shoulder and upper half of the forearm on both sides. Kidneys: decreased perfusion of the right kidney (relative to the left), moderate slowdown of urodynamics at the level of the calyx-pelvis complex on both sides.Conclusions. The reason for the development of rhabdomyolysis in the long-term period in the patient after suffering from COVID-19 was an increased muscle load. Targeted research and medical history can help identify signs of rhabdomyolysis. The use of the radionuclide diagnostic method makes it possible to identify areas of soft tissue damage with a one-step assessment of renal function in rhabdomyolysis in the acute period of the disease, as well as to evaluate the effectiveness of treatment with dynamic observation. When rhabdomyolysis is confirmed, it is necessary to carry out detoxification and infusion therapy, to monitor renal function in order to detect acute kidney injury, and in case of deterioration of renal function and intoxication, renal replacement therapy is indicated.

COVID-19 and Cardiovascular System. Part 3. COVID-19 Current Treatment Approaches: Evidence-Based Review

Unified management plan and treatment strategy for COVID-19 patients are yet to be discovered. Many trials on COVID-19 interventions have been registered or are ongoing. In this article the results of large-scale clinical trials on COVID-19 treatment are presented, the potential mechanism of action of some drugs is discussed, the features of the main pharmacological and non-pharmacological therapeutic options for COVID-19 patients are described.

Symptomatic Epileptic Seizures in Patients with Brain Gliomas

Introduction. Epileptic seizures are an important problem that significantly worsens the quality of patients’ life with both newly diagnosed and recurrent brain gliomas.Review. The analysis of domestic and foreign literature showed that low-grade gliomas, this symptom occurs on average in 76%, with high-grade gliomas – in 21% of patients. Despite the maximum allowable tumor resection, it is likely that epileptic seizures persist in 18-64% of patients, and in 5% of patients they first appear in the postoperative period. From 15 to 50% of epileptic seizures in cerebral gliomas are drug-resistant. In patients undergoing chemotherapy, it is better to use new antiepileptic drugs because their cross-effects are minimal.Conclusion. There is no generally accepted algorithm for prescribing and discontinuing antiepileptic drugs in patients with symptomatic epileptic seizures with cerebral gliomas. Further research is needed to determine the optimal combination and dosage regimen of antiepileptic drugs, especially during chemotherapy.

Emergency Carotid Endarterectomy for Internal Carotid Artery Thrombosis in the Course of COVID-19

A case of successful emergency carotid endarterectomy (CEE) in the acute period of ischemic stroke (within an hour after the onset of symptoms) in a patient with acute occlusive thrombosis of the internal carotid artery in the course of moderate-severe COVID-19 with a positive result of the polymerase chain reaction of the nasopharyngeal smear for SARS-CoV-2. The diameter of the ischemic focus in the brain according to multispiral computed tomography did not exceed 2.5 cm. The course of ischemic stroke was characterized by mild neurological deficit (score 5 according to National Institute of Health Stroke Scale). It was demonstrated that the severity of the patient’s condition was associated with bilateral, polysegmental, viral penvmonia with 65% damage to the lung tissue, a decrease in SpO2 to 93%. Laboratory noted coagulopathy with an increase in D-dimer (2837.0 ng/ml), prothrombin according to Quick (155.3%), fibrinogen (14.5 g/l) and signs of a “cytokine storm” with leukocytosis (28.4 10E9/l), an increase in C-reactive protein (183.5 mg/l), ferritin (632.8 ng/ml), interleukin-6 (176.9 pg/ml). The patient underwent glomus-sparing eversional CEE. The intervention was performed under local anesthesia due to the high risk of developing pulmonary barotrauma when using mechanical ventilation. To prevent the development of acute hematoma, a double active drainage was used into the paravasal space and subcutaneous fatty tissue (SFT). In case of thrombosis of one of the drainages, the second could serve as a spare. Also, upon receipt of hemorrhagic discharge from the drainage located in the SFT, the patient would not need to be transported to the operating room. Removal of skin sutures with revision and stitching of the bleeding source could be performed under local anesthesia in a dressing room. The postoperative period was uneventful, with complete regression of neurological symptoms. Used anticoagulant (heparin 5 thousand units 4 times a day s/c) and antiplatelet therapy (acetylsalicylic acid 125 mg at lunch). The patient was discharged from the hospital on the 12th day after CEE in satisfactory condition.

A Multidisciplinary Approach to the Treatment of COVID-Associated Complications After Pancreatoduodenal Resection (Case Report)

We report a clinical case of treatment of a complicated postoperative course in a patient who underwent pancreatoduodenal resection associated with coronavirus infection. Prevention and treatment of such complications have been suggested.Pancreatoduodenal resection (PDR) is indicated for malignant tumors of the pancreatic head, duodenum or its large papilla, distal common bile duct, as well as in chronic pancreatitis with a predominant lesion of the pancreatic head with severe pain syndrome.The given clinical observation describes an example of treatment of a patient who developed a series of thromboembolic complications in the early stages after PDR performed for a neuroendocrine tumor of the pancreatic head. The oncology disease, extensive surgery such as PDR, and the postoperative period itself are risk factors for the development of various thromboembolic complications. According to the literature, the incidence of thromboembolic complications after PDR is 3–3.3%.The reason for the atypical course of the postoperative period when performing pancreatoduodenal resection in patients with tumor of the pancreas may be conditions that are not directly related to either the pathology of the pancreas or the features of the surgical intervention. When analyzing the patient’s condition, one should take into account the conditions of treatment. In such situations, proper detection of COVID-19 and adequate correction of therapy can fundamentally change the outcome of the disease.

The First Experience of Aortic Valve Repeated Replacement Using the “Valve in Valve” Technique in a Patient With Dysfunction of a Biological Prosthesis

Introduction. Aortic valve replacement in cardiopulmonary bypass with suture fixation of the prosthesis is the “gold standard” in cardiac surgery. Currently, the frequency of use of heart valve bioprostheses is increasing in older patients. Despite all the advantages of using heart valve bioprostheses, this type of prosthesis has a major drawback - it is not durable. In most cases, the reason for the dysfunction of prostheses in the late postoperative period is early calcification of the prosthesis valves or their rupture due to degeneration. With the development of new “gentle” techniques for replacing heart valves, transcatheter aortic valve implantation was introduced into clinical practice. The use of transcatheter aortic valve implantation (TAVI) “valve in valve” for reoperations in older patients is of great interest, since in recent years the procedure has been widely used in clinical practice and shows promising data in patients with high surgical risk.Aim of study. Show first experience of using a technique «valve in valve» at N.V. Sklifosovsky Research Institute for Emergency Medicine.Material and methods. The results of surgical treatment of a patient with aortic valve bioprosthesis dysfunction using the TAVI “valve in valve” technique are presented.Results. The use of the TAVI “valve in valve” method made it possible to perform reprosthetics of the aortic valve (AV) from a transfemoral approach, not to increase the volume of intervention during reoperation, to avoid trauma to the structures of the heart and nearby tissues when accessing the AV in a patient with a high surgical risk.Conclusion. The use of the TAVI “valve in valve” method in cardiac surgery makes it possible to achieve good immediate and long-term results when it is necessary to replace the AV in patients with a high surgical risk.

The Analysis of the Main Working Parameters of the Head Regional Vascular Center of N.V. Sklifosovsky Research Institute for Emergency Medicine

Introduction. The regional vascular centers (RVC) network was created throughout Russia to manage cardiovascular diseases. On the basis of N.V. Sklifosovsky Research Institute for Emergency Medicine in Moscow, a center was created, which received the status of the head RVC. A comprehensive analysis of its work has not yet been carried out.Aim of study. To assess the main performance indicators and development directions of the head RVC based on the analysis of data for 2012–2019.Results. Analysis of the data obtained showed that by 2019 the flow of patient admissions increased 2.3-fold. At the same time, the use of the hospital bed fund does not exceed 100%, and the use of the intensive care bed fund has increased to 123%. A significant proportion of patients come with not field-specific diagnosis. The mortality, which is the main indicator of the quality of treatment in patients treated at the RVC, remained within 2.33–3%, which turned out to be 3 times lower in similar patients treated in other departments of the Institute.Discussion. Against the background of a constant increase in the number of hospitalizations, resusci-tation provision turned out to be insufficient when the number of hospital beds corre-sponded to the flow of admissions. The general lack of intensive care beds in the center and the lack of specialized intensive care for the department of vascular surgery forces the use of other intensive care units of the Institute. The admission of patients with other (not specific for RVC) diagnosis to the vascular center reduces the volume of highly specialized care for specialized patients.Conclusion. The analysis of the performance indicators of the head regional vascular center on the basis of N.V. Sklifosovsky Research Institute for Emergency Medicine, identified the need to expand the resuscitation bed fund in the existing departments of the center and organize specialized resuscitation for patients of the vascular surgery department. Also, the lack of intensive care beds is aggravated by a large flow of non-core admissions. Their reduction with the existing structure will provide significant savings in resources and will increase the number of treated profile patients and improve the quality of highly specialized care.

Autotransplantation of Flaps in the Treatment of Peri-Implant Infection After Osteosynthesis (Analysis of Clinical Observations)

Unfortunately, suppuration of a postoperative wound remains the most frequent complication of surgical intervention. If suppuration is located superficially, within the subcutaneous fat, it can be successfully managed with minimal functional losses. The clinical course is significantly complicated if the focus of infection is located under the skin, in the thickness of the muscles, in the fracture zone. In the case of suppuration in the area of osteosynthesis, the complication may become critical.Such a complication is a serious condition that requires multi-stage complex and sometimes multidisciplinary treatment.The conditions for a successful outcome in this pathology are the minimum period from the moment of suppuration, active surgical tactics, stability of the implant, and good vascularization of the surrounding soft tissues.Active surgical tactics involves the opening and sanitation of purulent foci, leaks, recesses. Staged necrectomies are inevitable companions of surgical treatment and can cause the formation of defects in the skin, subcutaneous tissue, and muscles.The resulting soft tissue defect leads to exposure of the bone and plate. Removal of the metal fixator becomes inevitable.Only the closure of the defect with a complex of tissues based on free vascularized composite grafts can radically solve the problem.The article presents two clinical observations of deep wound infection after bone osteosynthesis, where autotransplantation of a vascularized flap was used. The use of this technique made it possible to achieve suppression of infection, wound healing by primary intention, to create conditions for consolidation of the fracture, restoration of function and preservation of the limb as a whole.

Simultaneous Brachial Plexus Block and Combined Two-Segment Spinal-Epidural Anesthesia with Fixation of an Epidural Catheter in the Subcutaneous Canal in a Patient with Polytrauma

The article reports an example of the simultaneous use of brachial plexus block and combined two-segment spinal-epidural anesthesia with fixation of an epidural catheter in the subcutaneous canal in an 81-year-old patient after receiving a household injury - closed fracture of the olecranon of the right ulna with displacement of fragments and closed transtrochanteric fracture with a fracture of the right femur fragments. After preoperative preparation and examination, the patient underwent two consecutive surgical interventions within a day: open reduction of comminuted transtrochanteric fracture of the right hip, dynamic femoral screw osteosynthesis and open reduction of fracture of the right olecranon, Weber’s osteosynthesis. Surgical interventions were carried out under regional anesthesia: block of the brachial plexus via supraclavicular access and combined two-segment spinal-epidural anesthesia with a method developed in our clinic for fixing an epidural catheter in the subcutaneous canal using a modified spinal needle. After the operation, the patient underwent postoperative pain relief in the form of epidural analgesia for 72 hours. The postoperative period passed without complications. On the 13th day, the patient was discharged for outpatient treatment by a traumatologist. The use of local anesthesia in the form of two methods of regional anesthesia during two consecutive surgical interventions, in an elderly patient with a high anesthetic risk, followed by long-term postoperative anesthesia in the form of epidural analgesia with a reliable method of epidural catheter fixation in the subcutaneous canal without the use of narcotic analgesics, contributed to the successful carrying out two surgical interventions at once, early activation of the patient, absence of complications in the postoperative period. Reliable catheter fixation is very important for the quality of epidural analgesia. Dislocation of catheters by more than 2 cm can lead to migration of catheters from the epidural space, changing the course of anesthesia, deteriorating its quality, or even interrupting it altogether. The new method of catheter fixation in the subcutaneous canal developed by us made it possible to prevent catheter dislocation.
