Acute arterial thrombosis in SARS-CoV-2 infection

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, whose main expression is an acute respiratory syndrome, is also associated with concurrent multisystemic involvement, coagulation disorders and thrombotic complications, both in patients with prior diseases and those without. We present the case of a patient admitted to our hospital with no prior medical problems who had documented SARS-CoV-2 infection. During hospitalization, the patient developed acute left lower limb pain and absent pedal and posterior tibial pulses, with acute arterial ischemia due to thrombosis confirmed with imaging tests. Other causes of thrombosis such as atheromatosis, embolism and coagulation disorders, among others, were ruled out. He was anticoagulated with low-molecular-weight heparin and cilostazol throughout hospitalization and was discharged on warfarin and cilostazol. SARS-CoV-2-related acute arterial thrombosis should also be considered in our region. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2372).

La infección por síndrome respiratorio agudo severo-coronavirus-2 (SARS-CoV-2), cuya expre sión principal es el síndrome respiratorio agudo también se asocia a compromiso multisistémico y se han detectado coagulopatías y complicaciones trombóticas asociadas durante la infección, tanto en pacientes con patologías previas como sin ellas. Presentamos el caso de un paciente que ingresó a nuestro hospital sin antecedentes patológicos, con infección documentada por SARS-CoV-2. Durante la hospitalización presentó dolor agudo de miembro inferior izquierdo con ausencia de pulsos pedio y tibial posterior, confirmándose por estudios imagenológicos isquemia arterial aguda por trombosis. Se descartaron otras causas de trombosis como ateromatosis, embolia, coagulopatía, entre otros. Recibió anticoagulación con heparinas de bajo peso molecular y cilostazol durante el periodo de hospitalización y egresó con warfarina y cilostazol. La trombosis arterial aguda relacionada con infección por SARS-CoV-2 debe considerarse también en nuestra región. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2372).

Isquemia arterial aguda trombótica pos-COVID-19 / Post-COVID-19 acute thrombotic arterial ischemia

La pandemia por COVID-19, ocasionada por el virus SARS-CoV-2, ha producido una alta incidencia de coagulopatía asociada a un aumento en la morbi-mortalidad en los pacientes que la padecen. La coagulopatía resulta principalmente trombótica, determinada por daño endotelial, inflamación, trampas extracelulares de neutrófilos, activación de macrófagos y tormenta de citocinas que mantienen el círculo vicioso de la inflamación y la trombosis. Los eventos trombóticos observados durante la COVID-19 fueron principalmente tromboembólicos venosos e infarto del miocardio; sin embargo, la evidencia mostró el incremento de una complicación vascular que no había sido descrita: la trombosis arterial periférica aguda. El objetivo de este artículo fue exponer la infrecuencia de la isquemia arterial aguda como forma de presentación clínica de la COVID-19. Se presenta un paciente masculino de 54 años, con dolor intenso localizado a nivel de la extremidad inferior derecha, gradiente térmico, palidez, cianosis distal e impotencia funcional, con diagnóstico clínico y ecográfico de isquemia arterial aguda de causa trombótica del sector arterial femoral e ilíaco externo derechos. La evolución del paciente resultó satisfactoria y se mantiene bajo seguimiento médico para evaluar la permeabilidad del sector arterial desobstruido(AU)

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has produced a high incidence of coagulopathy associated with an increase in morbidity and mortality in patients suffering from it. Coagulopathy is mainly thrombotic, determined by endothelial damage, inflammation, extracellular neutrophil traps, macrophage activation and cytokine storm that maintain the vicious cycle of inflammation and thrombosis. The thrombotic events observed during COVID-19 were mainly venous thromboembolic and myocardial infarction; however, the evidence showed an increase in a vascular complication that had not been described: acute peripheral arterial thrombosis. The objective of this article was to expose the infrequency of acute arterial ischemia as a form of clinical presentation of COVID-19. A 54-year-old male patient with severe pain located at the level of the right lower extremity, thermal gradient, pallor, distal cyanosis and functional impotence, with a clinical and ultrasound diagnosis of acute arterial ischemia of thrombotic cause of the right femoral and iliac arterial sector is presented. The evolution of the patient was satisfactory and he is kept under medical follow-up to evaluate the permeability of the unobstructed arterial sector(AU)

Trombolisis dirigida por catéter en paciente con oclusión arterial periférica aguda / Catheter-directed thrombolysis in patients with acute peripheral arterial occlusion

Introducción: Las oclusiones arteriales periféricas agudas de menos de 14 días y de causa embólica y trombótica están asociadas a una alta morbimortalidad. La trombólisis dirigida por catéter representa en la actualidad una modalidad de tratamiento efectivo para la oclusión de vasos distales infrageniculares, que históricamente ha tenido malos resultados mediante embolectomía convencional, debido a la oclusión preexistente de vasos colaterales y al daño mecánico al endotelio, que conlleva esta técnica tradicional. Se decidió presentar este caso por ser la primera vez que se practica esta modalidad de tratamiento en Cuba. Objetivo: Exponer los resultados obtenidos con la aplicación de la trombolisis fibrinolitica mediante catéter en un paciente afectado por trombosis arterial periférica aguda. Presentación del caso: Paciente masculino de 57 años de edad con diagnóstico de trombosis arterial aguda de la arteria poplítea del miembro inferior izquierdo, con más de 24 horas de evolución de la isquemia y del compromiso de la viabilidad de la extremidad. Se utilizó el tratamiento fibrinolítico, mediante infusión de 250 000 unidades de Heberkinasa® en tres horas y se logró la mejoría del nivel de amputación. Conclusiones: El tratamiento fibrinolítico con Heberkinasa® fue útil en el paciente tratado porque redujo el nivel de amputación en el paciente, que presentó isquemia irreversible y criterio inicial de amputación supracondílea alto, en la extremidad comprometida(AU)

Introduction: Acute peripheral arterial occlusions of less than 14 days and of embolic and thrombotic cause are associated with a high morbidity and mortality. Catheter-directed thrombolysis currently represents an effective treatment modality for the occlusion of infragenicular distal vessels, which has historically had poor results by conventional embolectomy, due to the pre-existing occlusion of collateral vessels and the mechanical damage to the endothelium, which this traditional technique entails. It was decided to present this case because it is the first time that this modality of treatment is practiced in Cuba. Objective: Present the results obtained with the application of fibrinolytic thrombolysis by catheter in a patient affected by acute peripheral arterial thrombosis. Case presentation: A 57-year-old male patient diagnosed with acute arterial thrombosis of the popliteal artery of the left lower limb, with more than 24 hours of evolution of ischemia and compromised viability of the limb. Fibrinolytic treatment was used, by infusion of 250,000 units of Heberkinase® in three hours and the improvement of the amputation level was achieved. Conclusions: Fibrinolytic treatment with Heberkinase® was useful in the treated patient because it reduced the level of amputation in the patient, who presented irreversible ischemia and initial criteria of high supracondylar amputation in the compromised limb(AU)

Clinical analysis of hepatic arterial thrombolysis combined with splenic arterial embolization in treatment of hepatic arterial thrombosis after liver transplantation / 器官移植

Objective To analyze the clinical efficacy of transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization in the treatment of hepatic artery thrombosis (HAT) after liver transplantation. Methods Clinical data of 9 patients diagnosed with HAT after liver transplantation undergoing transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization were retrospectively analyzed. The incidence of HAT and clinical efficacy of thrombolytic therapy were summarized. The incidence of thrombolysis related complications and clinical prognosis were evaluated. The thrombolytic therapy procedures of typical cases were analyzed. Results HAT was diagnosed at 1-66 d after liver transplantation with a median time of 10 d. The formation site of HAT was found at the anastomosis of the main hepatic artery in 8 cases and at the right branch in 1 case. Upon diagnosis, 9 patients received transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization in emergency. The hepatic artery was open during operation in 4 cases and treated with postoperative thrombolytic therapy with indwelling catheter in 3 cases. The opening time for inwelling catheter was 72-96 h. The total successful rate was 7/9. The thrombolysis related complication of abdominal hemorrhage occurred in 1 case after surgery. Three cases died, including 2 cases of liver failure and infection, and 1 case of biliary ischemia and systemic infection at 70 d after interventional therapy. Conclusions Hepatic arterial thrombolysis combined with splenic arterial embolization is an efficacious treatment for HAT after liver transplantation, which can serve as the optimal therapy for patients who are unable to undergo secondary liver transplantation.

Case report and literature review of tongue artery embolism caused by hyaluronic acid augmentation of chin / 中华整形外科杂志

In December 2018, a 29-year-old female patient with lingual artery embolism after hyaluronic acid injection was admitted to the Second Affiliated Hospital of Kunming Medical College. The examination showed swelling tongue, the mucosa on the front and back of the right tongue became white, and the tip of the tongue slightly atrophied. The movement of tongue was disturbed. The patient′s pronunciation was unclear. The right tongue was numb, resulted by the weak circulation. Hyaluronidase was injected into tongue. The vasodilator was used. And hyperbaric oxygen chamber was applied. Thereafter, the blood supply and oxygen concentration of embolized area were increased, and collateral circulation was established. Antibiotic therapy and continuous treatment with neurotrophic drugs (rat nerve growth factor + methylcobalt ammonium) were given to promote the repair of nerve. After treatment, the embolism of lingual artery was significantly improved. Three months later, the patients had mild muscular atrophy on the right side of the tongue, with partial recovery of the right tongue mucosa. Tongue movement, sensory and taste functions recovered. Hyaluronic acid injection needs to be standardized, performed by surgeons who masters the anatomical structures, the injection layer and spot. If the vascular embolism occurs, hyaluronidase should be used as early as possible. It also needs to reduce local tension in both injected and affected area, reduce the pressure of injection on blood vessels, improve local blood circulation, so as to achieve better therapeutic effect.

Curative Effect Observation of Acarbose Intervene in Cerebral Arterial Thrombosis Complicated with Im-paired Glucose Tolerance / 中国药师

Objective:To observe the intervention effect of acarbose on cerebral arterial thrombosis complicated with impaired glu-cose tolerance(IGT).Methods: Totally 120 cases of IGT patients with ischemic stroke were randomly divided into the observation group (58 cases) and the control group(62 cases). The two groups were given the same basic treatment,while the observation group was treated with acarbose 50 mg,po,tid for 3 months additionally. Before and after the treatment,the levels of blood lipid and blood glucose,serum high-sensitivity C reactive protein(hsCRP) and carotid intima media thickness(IMT) and the other adverse drug reac-tions were detected in the two groups. After 6-month follow-up,the new incidence of IGT was compared between the groups.Results:After the treatment,2 hPG,HbAlc,hsCRP and the other indicators in the observation group were significantly improved when com-pared with those before the treatment(P<0.01 or P<0.05),while only hsCRP in the control group was significantly improved when compared with that before the treatment(P<0.05) and that in the observation group. 2 hPG,HbAlc,hsCRP,IMT and the other in-dicators in the observation group were significantly better than those in the control group(P<0.01 or P<0.05). There was no signifi-cant change in the level of blood lipid in the two groups. There was no adverse drug reaction during the treatment. After the 6-month follow-up,the new incidence of IGT in the observation group was 1.82%,which was significantly lower than that in the control group (7.27%,P<0.05).Conclusion: Among the patients with cerebral arterial thrombosis complicated with impaired glucose tolerance, the normal treatment measures plus acarbose can effectively delay carotid artery IMT incrassation and decrease the risk of cardiovascular events recurrence with better relative safety.

Application of thrombelastogram in choosing antiplatelet drug for patients with cerebral arterial thrombosis / 中国医学装备

Objective:To investigate the application value of thromboelastography (TEG) in choosing antiplatelet drug for patients with cerebral arterial thrombosis.Methods: 100 new patients with cerebral arterial thrombosis, who received single antiplatelet therapy after received dual antiplatelet therapy (aspirin and clopidogrel) in acute stage (14d), were randomly divided into observation group (50cases)and control group (50cases). According to different method of choosing drug, patients of control group randomly were implemented different single antiplatelet drug, while patients of observation group received more sensitive antiplatelet drug based on TEG results. The follow-up observation about recurrent situation of cerebral arterial thrombosis for the two groups were carried out in further study.Results: In one year, the recurrence rate of cerebral arterial thrombosis of observation group (6%, 3/50) was significantly lower than that of control group (20%, 10/50) (x2=4.332,P<0.05). The differences of recurrence rate between different antiplatelet drug in intra-group were not statistically significant.Conclusion: TEG can efficiently evaluate the therapeutic effect of antiplatelet drug, and guide the selection for drug so as to reduce the recurrence rate of cerebral arterial thrombosis.

Advances in the research of therapeutic targets and the development of new drugs against arterial thrombosis / 中国药科大学学报

Arterial thrombosis (AT) is a common disease which usually causes acute myocardial infarction,ischemic stroke and other ischemic cardiovascular and cerebrovascular diseases,which shows high rates of morbidity and mortality,and has become a serious problem to human health.It is increasingly clear that the interactions among platelets,the endothelium and leukocytes are important throughout all stages of the atherothrombotic process.It is of great significance to search for therapeutic targets in the process of AT and developing the therapeutic drugs based on those newly discovered targets.This article reviews the research advances in the discovery of antithrombotic targets and the current situation of drug development based on those antithrombotic targets found in the recent 5 years,in order to provide some references or clues for the development of innovative drugs to prevent and treat AT.

Enoxaparin Therapy for Arterial Thrombosis After Umbilical Cord Catheterization in Preterm Infants

The incidence of symptomatic thrombosis of umbilical arterial catheterization is 1-3%. Therapeutic options may include: using heparin or low molecular weight heparin, using a thrombolytic agent, or surgical thrombectomy. However, there are insufficient data to recommend any one treatment over the others. Recently, enoxaparin, a low molecular weight heparin, has emerged as a drug of choice for the treatment of neonatal thrombosis due to pharmacologic stability over unfractionated heparin or thrombolytic agents. We report a case of successful treatment of aortic thrombosis after umbilical arterial catheterization with enoxaparin in preterm infants.

Recurrent Arterial Thrombosis as a Presenting Feature of a Variant M3-Acute Promyelocytic Leukemia

Acute limb ischemia (ALI) is a common vascular emergency. Hematologic malignancies are commonly associated with derangement of normal hemostasis and thrombo-hemorrhagic symptoms during the course of the disease are common. However, ALI as an initial presenting feature of acute leukemia is rare. Due to the rarity of this presentation, there is a scarcity of prospective randomized data to optimally guide the management of these patients. Current knowledge is mainly based on isolated cases. We report our experience managing a patient who presented with ALI and was found to have occult leukemia. A review of all cases with ALI as a presenting feature of acute leukemia is also presented.

Effect and nursing of enhanced external counterpulsation on patients with ischemic cerebral apoplexy / 现代临床护理

Objective To explore the curative effect and nursing of enhanced external counterpulsation (EECP) on patients with ischemic cerebral apoplexy. Methods In September 2013 to March 2013 in Shenzhen Futian District People′s Hospital neurology hospital, toally 286 patients with ischemic cerebral apoplexy were randomly divided into two groups, control group and treatment group with 143 cases in each group. The control group used conventional treatment and the treatment group used EECP. The score of clinical nerve function and defect improved Barthel index were compared. Result The score of clinical nerve function defect and improved Barthel index of the treatment group before the treatment were without difference (all P>0.05). The score of clinical nerve function defect and improved Barthel index of the treatment group were less than those of control group after the treatment (all P < 0.05). Conclusion Ischemic stroke patients with positive EECP can significantly increase clinical neural function and life ability , improve patient′s quality of life.

Lytic Infusion versus Bolus Therapy for Peripheral Arterial Thrombosis Management: The LIBRA Pilot Study.

Objective: To compare two intra-arterial catheter-directed thrombolysis (CDT) techniques (bolus vs infusion) with respect to clinical outcomes and resource utilization in the management of peripheral arterial thrombosis. Methods: In a retrospective single-center study, 20 consecutive patients with acute or sub-acute thrombosis received tissue plasminogen activator (tPA) treatment administered either as a bolus via an irrigating balloon catheter (CDT-CLEARWAY group; n=10) or as a bolus followed by a continuous infusion using a traditional infusion catheter (CDT-INFUSION; n=10). Adjunctive therapies were administered at the discretion of the operator. Patients were followed for 30 days post-intervention for complications and major adverse clinical events. Results: All 20 patients (12 men; median age 71) had Rutherford clinical stages 4-6 at presentation. Procedural success was achieved in all cases. The mean tPA amount required was reduced in the CDT-CLEARWAY group (8.9 mg vs 32.9 mg), as was the mean time to patency (2.2 hrs vs 16 hrs, P<.001). There were no bleeding complications in the CDT-CLEARWAY group while one patient in the CDT-INFUSION developed intracranial and gastrointestinal hemorrhage. The CDT-CLEARWAY procedure was associated with a significant reduction in mean length of hospital stay (2.2 vs. 5.6 days, P<.001) and mean total cost, which were mostly due to the lack of ICU requirement for the CDT-CLEARWAY group. More patients in the CDT-CLEARWAY group (7/10 patients vs. 1/10 patients) underwent adjunctive thrombectomy procedures following disruption of the thrombus in the target vessel. Conclusion: Significant reductions in total cost, amount of tPA used, and hospital stay were accomplished using a bolus dose of thrombolytic therapy through an irrigating balloon catheter versus a maintenance infusion dose through a standard infusion catheter, while maintaining the efficacy in restoring flow in target vessels.

Significantly reduced function of T cells in patients with acute arterial thrombosis / 老年心脏病学杂志（英文版）

Objectives To explore the intrinsic factors related to the pathogenesis of acute arterial thrombosis (AAT) and to elucidate the patho-genesis of AAT on the basis of differentially expressed genes. Methods Patients with acute myocardial infarction (AMI), stable angina (SA) and healthy controls (n=20 per group) were recruited, and the whole human genome microarray analysis was performed to detect the dif-ferentially expressed genes among these subjects. Results Patients with AMI had disease-specific gene expression pattern. Biological func-tional analysis showed the function of T cells was significantly reduced, the mitochondrial metabolism significantly decreased, the ion me-tabolism was abnormal, the cell apoptosis and inflammatory reaction increased, the phagocytosis elevated, the neutrophil-mediated immunity increased and the post-traumatic repair of cells and tissues increased in AMI patients. The biological function in SA group and healthy con-trols remained stable and was comparable. Conclusions The reduced function of T cell gene models in AAT showed the dysfunction of the immune system. The pathogenesis of AAT may be related to the inflammatory reaction after arterial intima infection caused by potential pathogenic microorganisms.

A Case of Repeated Acute Limb Ischemia with Malignant Tumor / 日本心臓血管外科学会雑誌

A 72-year-old man had undergone aorto-bifemoral bypass for Leriche syndrome at age 67, but acute limb ischemia developed three times after the first operation, in January 2008, April 2008, and April 2009. There were no abnormal heart rhythms or thrombotic factors, and he had received anticoagulant therapy with warfarin (target prothrombin time-international normalized ratio : 1.7 to 3.0) since January 2008. Nevertheless, he came to our hospital because of sudden onset of severe pain in the right lower limb in April 2010. Since CT showed occlusions in the right leg involving the aortobifemoral bypass and femoropopliteal bypass graft, emergency thrombectomy and femoropopliteal bypass (below knee), was performed. CT on admission showed enlargement of lymph nodes around the stomach, and gastric cancer was diagnosed by esophagogastroduodenoscopy. Since we considered the hypercoagulability in this patient with cancer to have resulted in repeated acute arterial thrombosis, these episodes were broadly diagnosed as Trousseau's syndrome.

Trombosis postraumática de la arteria humeral / Post-traumatic thrombosis of the humeral artery

Los traumatismos vasculares son cada vez más frecuentes. El aumento de la violencia ha incrementado de forma gradual las heridas provocadas por armas blancas y proyectiles. Se presenta un caso de traumatismo de arteria humeral, su diagnóstico y el tratamiento aplicado, en un paciente del sexo masculino, de 28 años de edad, politraumatizado por accidente del tránsito, con múltiples fracturas a nivel de la pelvis, clavícula y varias costillas, así como herida de 8 cm en cara interna del brazo derecho, en su tercio superior con gran hematoma. Se constató una herida anfractuosa a nivel de la cara interna del brazo, cianosis de la mano y tercio inferior del antebrazo. A la palpación existía ausencia de los pulsos radial, cubital y humeral, así como frialdad de la mano y disminución de la fuerza muscular. El eco-Doppler arterial evidenció disminución significativa del flujo por debajo de la zona lesionada. Se procedió a la exploración del trayecto vascular encontrándose trombo que ocluía la luz de la arteria humeral con lesión de la íntima. Se realizó trombectomía y colocación de prótesis arterial, con lo que se logró la recuperación de los pulsos y hubo una evolución favorable. El manejo exitoso del traumatismo arterial depende de su diagnóstico precoz y del tratamiento oportuno

Vascular trauma is on the increase. The occurrence of stabbings and gunshot wounds has gradually risen as a result of the spread of violence. A case is presented of humeral artery trauma, its diagnosis and treatment, in a male 28-year-old patient polytraumatized in a traffic accident, with multiple fractures at the level of the pelvis, clavicle and several ribs, and an 8 cm wound on the inner side of the right arm, on its upper third, with a large hematoma. An anfractuous wound was found on the inner side of the arm, as well as cyanosis of the hand and lower third of the forearm. Palpation revealed an absence of radial, cubital and humeral pulse, as well as hand coldness and a decrease in muscular strength. Arterial Doppler echo showed a significant flow decrease below the injured area. Exploration of the vascular tract revealed a thrombus occluding the lumen of the humeral artery with a lesion of the intima. A thrombectomy was performed with placement of an arterial prosthesis, as a result of which pulse was recovered. A favorable evolution followed. Successful management of arterial trauma depends on its early diagnosis and timely treatment.
