ABSTRACT

Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

ABSTRACT

Sub?macular hemorrhage poses a potential threat to vision if left untreated. The preferred surgical technique to clear sub?macular hemorrhage includes vitrectomy followed by retinotomy using a 41G needle with subsequent injection of recombinant tissue plasminogen activator (r?tPA) followed by air/SF6 injection into the sub?retinal space. A malleable nature, increased resistance, and the cost of the 41G needle limit its use. We evaluated the safety and efficacy of a 26G needle for retinotomy as a supplement for the 41G needle in a series of six subjects with sub?macular hemorrhage. A slight modification in the procedure was done by injecting air into the sub?retinal space prior to the r?tPA injection. We found that our technique of using the 26G needle for retinotomy is safe and effective due to its stable nature and self?sealing properties. An air injection prior to r?tPA allows for increased bioavailability of the drug by preventing efflux due to its tamponading effect.

ABSTRACT

Objective:To investigate the effects of Danhong injection combined with intravenous recombinant tissue plasminogen activator (rt-PA) on cardiac function, myocardial zymogram and lipoprotein associated phospholipase A2 (Lp-PLA2) level in older adult patients with acute myocardial infarction (AMI). Methods:Eighty older adult patients with acute myocardial infarction who received treatment in Community-based General Hospital of Shaoxing Central Hospital, China between January 2017 and December 2019 were included in this study. They were randomly assigned to receive either intravenous thrombolysis with rt-PA (control group, n = 40) or Danhong injection combined with intravenous thrombolysis with rt-PA (observation group, n = 40). The changes in traditional Chinese medicine syndrome score, left ventricular ejection fraction, left ventricular end diastolic diameter, creatine kinase, creatine kinase-MB and lipoprotein associated phospholipase A2 level as well as adverse cardiovascular events were compared between the control and observation groups. Results:After treatment, the score of chest tightness, dark purple tongue, palpitation and shortness of breath in the two groups were decreased. After treatment, the score of chest tightness, dark purple tongue, palpitation and shortness of breath in the observation group was (2.13 ± 0.31) points, (1.98 ± 0.41) points, (1.77 ± 0.29) points, respectively, which was significantly lower than that in the control group [(2.98 ± 0.37) points, (2.52 ± 0.56) points, (2.13 ± 0.32) points, t = 11.137, 4.920, 5.272, all P < 0.001]. After treatment, left ventricular end diastolic diameter in each group was decreased compared with before treatment. After treatment, left ventricular end diastolic diameter in the observation group was significantly lower than that in the control group [(46.12 ± 4.11) mm vs. (49.74 ± 4.32) mm], and left ventricular ejection fraction in the observation group was significantly higher than that in the control group [(47.02 ± 3.55) % vs. (43.25 ± 4.10) %, t = 3.839, 4.396, both P < 0.001). After treatment, Lp-PLA2, creatine kinase, creatine kinase-MB levels in each group were decreased compared with before treatment. After treatment, Lp-PLA2, creatine kinase, creatine kinase-MB levels in the observation group were (171.02 ± 12.52) μg /L, (10.52 ± 2.11) U/L, (24.12 ± 3.52) U/L), respectively, which were significantly lower than those in the control group [(189.63 ± 11.98) μg/L, (14.71 ± 2.62) U/L, (32.79 ± 4.79) U/L), t = 6.792, 7.877, 9.224, all P < 0.001]. The incidence of adverse cardiovascular events in the observation group was significantly lower than that in the control group (5.00% vs. 22.50%, χ2 = 5.165, P < 0.05). Conclusion:Danhong injection combined with intravenous rt-PA for the treatment of acute myocardial infarction in older adult patients can greatly decrease traditional Chinese medicine syndrome score, improve cardiac function, regulate myocardial zymogram and Lp-PLA2 levels, and decrease the incidence of adverse cardiovascular events.

ABSTRACT

To study the effect of modified Buyang Huanwu Decoction on the hemorrhagic transformation after intravenous thrombolysis of recombinant tissue type plasminogen activator(rt-PA) in patients with super early(onset time<4. 5 h) cerebral infarction. From March 2016 to July 2018,at the brain disease zone of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,212 cases of super early cerebral infarction were selected and divided into two group according to the randomized complete blocks designs: control group(106 cases) and traditional Chinese medicine group(106 cases). The control group was treated with rt-PA intravenous thrombolysis,while the traditional Chinese medicine group was treated with modified Buyang Huanwu Decoction in addition to the therapy of the control group. Both groups were treated for 14 days. Neurological deficit score,serum matrix metalloproteinase-9(MMP-9),neuron specific enolase(NSE),vascular endothelial growth factor(VEGF) and plasma cellular fibronectin(c-FN) levels,the incidence of hemorrhagic transformation,clinical efficacy and adverse drug reactions before and after treatment were compared between the two groups. According to the findings,at the 14 thday after treatment,the rank sum test of the grade data showed that the clinical efficacy of the traditional Chinese medicine group was better than that of the control group(Z =-2. 033,P = 0. 042); on the basis of χ2 test,the total efficiency of the traditional Chinese medicine group was higher than that of the control group(χ2= 4. 895,P =0. 027); the hemorrhagic transformation rate of the traditional Chinese medicine group was lower than that of the control group within14 days of treatment(χ2= 3. 962,P = 0. 047). MMP-9 levels in the traditional Chinese medicine group were lower than those in the control group at the 3 rd,5 th,7 th,10 th,14 thd after treatment(t =-2. 474,-3. 022,-5. 163,-6. 998,-9. 821; P = 0. 014,0. 003,0,0,0). The improvement of c-FN,NSE,VEGF and NIHSS scores in the traditional Chinese medicine group was superior to that of the control group after 14 days of treatment(t =-2. 343,-3. 187,-2. 129,-3. 105; P = 0. 020,0. 002,0. 034,0. 002). No obvious adverse reactions of modified Buyang Huanwu Decoction were observed during 14 days of treatment. Modified Buyang Huanwu Decoction could reduce the expressions of MMP-9,c-FN,NSE and VEGF after rt-PA intravenous thrombolysis in patients with super early cerebral infarction,and decrease the hemorrhagic transformation rate after thrombolysis,with high safety.

ABSTRACT

Resumen El factor de riesgo más importante para presentar una enfermedad cerebrovascular (EVC) es la edad. El ictus es la causa más frecuente de discapacidad adquirida en la edad adulta. De acuerdo con la Organización Mundial de la Salud, se estima que en el año 2050, casi la mitad de la población mayor de 65 años podría sufrir o haber sufrido un EVC. Debido a la gran incidencia y al impacto negativo que tiene esta enfermedad, presentamos el caso clínico de una trombólisis exitosa en una paciente con ictus isquémico y crisis hipertensiva en el Servicio de Urgencias. Ponemos de manifiesto la adecuada evaluación con las diferentes escalas existentes, clínicas, radiológicas y pronósticas (NIHSS, Dragon Score, ASPECT, HAT score), así como los criterios de inclusión y exclusión, los cuales son indispensables para administrar una terapia de repercusión intravenosa. Conclusiones En México, los casos reportados con trombólisis exitosa son sólo el 5%. En este caso de éxito, la adecuada actuación en el Servicio de Urgencias de primer contacto impactó de manera positiva en el pronóstico de la paciente, ya que el diagnóstico oportuno y la administración de rTPA (activador tisular del plasminógeno) evitó secuelas importantes y consiguió una mejor calidad de vida -la cual se ve disminuida hasta en 70% de los pacientes que sufren un EVC (según estudios realizados en los EUA)-.


Abstract The most important risk factor for presenting a cerebrovascular disease (CVA) is age. Stroke is also the most frequent cause of disability acquired in adulthood. According to the World Health Organization, it is estimated that by the year 2050, almost half of the population over 65 could suffer or have suffered a CVA. Due to the high incidence and negative impact of this disease, we present a clinical case of successful thrombolysis in a patient with ischemic stroke and hypertensive crisis in the emergency department. We emphasize the adequate evaluation with the different existing clinical, radiological and predictive scales (NIHSS, Dragon Score, ASPECT, HAT score), as well as the inclusion and exclusion criteria, which are indispensable to administer an intravenous reperfusion therapy. Conclusions In Mexico, the cases reported with successful thrombolysis are only 5%. In this successful case, the proper performance in the emergency service impacted positively on the prognosis of the patient, since the timely diagnosis and administration of rTPA avoided important sequelae and provided a better quality of Life, which is decreased in up to 70% of patients suffering from a CVA (according to studies conducted in the USA).

ABSTRACT

Background: Stroke is one of the common causes of mortality and disability. By introducing r-TPA into the global drug market and its effect on the patients’ prognosis, using this drug is recommended in all patients with ischemic stroke who visited less than 4.5 hours after stroke and do not have contraindications. The aim of this study was to investigate the frequency of stroke patients qualified for recombinant tissue plasminogen activator (r-TPA) and its limtations.Methods: In this descriptive cross-sectional study, 244 patients examined with stroke admitted to the Neurology Department of Zahedan city hospital in 2016. Information form were completed with demographic data, transmission method, referral time, CT scan preparation time, and the response of the patients' trials, and finally the data were inserted in SPSS.16 software and analysed by statistical methods.Results: Out of all patients with ischemic stroke, 28 (11.5%) patients had contraindication to receive drug. Of 216 remain patients, 201 patients (93.1%) had no possibility to receive r-TPA due to the loss of golden time and only 15 patients (6.9%) had possibility to receive drug because of visited 4.5 hours before the beginning of symptoms. Of them, 3 (20%) patients due to delay in CT scan and test results, had no possibility to receive r-TPA. In summary, of all patients with inclusion criteria, only 12 (5.5%) patients could use the r-TPA in this study.Conclusions: The most important barrier to using r-TPA has been the loss of golden time and training to raise awareness of the society can lead to early referral from the onset of stroke symptoms.

ABSTRACT

Acute ischemic stroke (AIS) has the characteristics of high morbidity, disability and mortality. Intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) for AIS in time window is an effective treatment recommended by domestic and overseas guidelines. However, intravenous thrombolysis has shortcomings, such as short time window, low recanalization rate and high risk of bleeding. Therefore, in recent years, studies on prolonging the time window, using low-dose rt-PA or a new generation of thrombolytic agent, and thrombolysis combined with anti-thrombotic therapy have been carried out worldwide. Based on the studies on intravenous thrombolysis, this paper discusses several issues, including extending time window, low-dose rt-PA thrombolysis, and new generation of thrombolytic agent.

ABSTRACT

Background: Although acute pancreatitis is listed among the exclusion criteria for the administration of recombinant tissue plasminogen activator according to the Japanese Guideline for the Management of Stroke, the co-occurrence of acute pancreatitis and acute ischemic stroke has not been investigated. The present study aimed to assess the incidence rate of acute pancreatitis in patients with acute ischemic stroke.Methods: This study consecutively enrolled all patients with ischemic stroke admitted to the Department of Neurology, JA Toride Medical Center between April 2014 and March 2016. Diagnosis of acute pancreatitis was made according to the revised Atlanta Classification of Acute Pancreatitis. We retrospectively analyzed serum amylase activity and the frequency of acute pancreatitis as a comorbidity of ischemic stroke.Results: A total of 411 ischemic stroke patients were included. Serum amylase activity was measured for 364 patients, 27 of whom presented with amylase activity exceeding the upper limit of normal. In two patients with serum amylase activity greater than three times-fold the upper limit of normal, computed tomography or transabdominal ultrasonography showed no characteristic findings of acute pancreatitis. No patient in the cohort met the diagnostic criteria for acute pancreatitis.Conclusions: Acute pancreatitis is a very rare comorbidity of acute ischemic stroke.

ABSTRACT

The efficacy and safety of recombinant tissue plasminogen activator (rtPA) need to be improved due to its low bioavailability and requirement of large dose administration.The purpose of this study was to develop a fibrin-targeted nanoparticle (NP) drug delivery system for thrombosis combination therapy.We conjugated rtPA to poly(ethylene glycol)-poly(ε-caprolactone) (PEG-PCL) nanoparticles (rtPA-NP) and investigated its physicochemical characteristics such as particle size,zeta potential,enzyme activity of conjugated rtPA and its storage stability at 4℃.The thrombolytic activity of rtPA-NP was evaluated in vitro and in vivo as well as the half-life of rtPA-NP,the properties to fibrin targeting and its influences on systemic hemostasis in vivo.The results showed that rtPA-NP equivalent to 10% of a typical dose of rtPA could dissolve fibrin clots and were demonstrated to have a neuroprotective effect after focal cerebral ischemia as evidenced by decreased infarct volume and improved neurological deficit (P<0.001).RtPA-NP did not influence the in vivo hemostasis or coagulation system.The half-life of conjugated rtPA was shown to be approximately 18 times longer than that of free rtPA.These experiments suggested that rtPA-conjugated PEG-PCL nanoparticles might be a promising fibrin-targeted delivery system for a combination treatment of thrombosis.

ABSTRACT

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11%vs. 53.61%, P0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

ABSTRACT

Objective To observe the effect of early using butylphthalide injection before and after thrombolytic therapy with intravenous recombinant tissue plasminogen activator (rt-PA) on the clinical prognosis of patients with ultra-early acute cerebral infarction (ACI). Methods A prospective study was conducted, 81 patients with ACI admitted to the Department of Neurology of Tangshan Worker's Hospital from September 2014 to March 2016 were enrolled, and they were divided into a control group (40 cases) and an observation group (41 cases) according to the random number table. Both groups were given routine treatments, such as drugs for lowering blood pressure and blood sugar, decreasing blood lipid to stabilize plaque, neuroprotection, activating blood circulation and removing blood stasis, etc. On the basis of conventional treatment, the control group was directly treated with rt-PA intravenous (IV) thrombolytic therapy according to the guidelines of thrombolytic therapy; in the observation group, the patients immediately underwent CT head examination after admission to decide whether the thrombolytic therapy was necessary, if the therapy was decided to be done, during doctors waiting for the laboratory results or transferring patients, IV drip of butylphthalide sodium chloride 100 mL. After IV drip thrombolytic therapy, if the disease condition was stabilized, the head CT was re-examined to exclude intracranial hemorrhage, if no such hemorrhage, IV drip of butylphthalide sodium chloride 100 mL was continuously given, twice daily for consecutive 14 days with the interval between the two times of IV drip being 7 hours daily. When patient's condition was changed, the re-examination of head CT could be done at any time; if the patient's condition was not changed, the head CT was routinely performed 24 hours after IV drip thrombolysis. After exclusion of intracranial hemorrhage, the patients in both groups were treated additionally by the platelet aggregation drug on the basis of their original treatment. The National Institutes of Health Stroke Scale (NIHSS) scores, Bartherl index (BI) scores were recorded before and after treatment, and the recovery situation of neurological function, hemorrhage conversion rate, mortality and adverse reactions were observed after thrombolysis. Results After treatment, the NIHSS scores were lower, and the BI index scores were higher than those before treatment in the two groups, and the change in the observation group after 14 days of treatment was more significant (NIHSS score: 3.87±3.46 vs. 7.37±4.18, BI score: 87.38±9.34 vs. 75.67±8.05, both P < 0.05); the total effective rate of the observation group was significantly higher than that of the control group [73.2% (30/41) vs. 55.0% (22/40), P < 0.05], the rate of bleeding conversion rate was lower than that of the control group [2.4% (1/41) vs. 7.5% (3/40), P < 0.05], the difference in fatality rate between the two groups was not statistically significant [2.4% (1/41) vs. 2.5% (1/40), P > 0.05]. Conclusion The clinical therapeutic effect of butylphthalide injection is relatively good for treatment of patients with ultra-early ACI.

ABSTRACT

Objective To observe the curative effect and safety of recombinant tissue plasminogen acti-vator (rt-PA) in acute ischemic stroke (AIS) patients in more than 15 points of NIHSS scores and less than 4.5 h in onset time. Methods One hundred and twenty-seven cases with AIS in more than 15 points of NIHSS scores and less than 4.5 h in onset time were included into the study. According to the patients′ option to accept the intravenous thrombolytic therapy , 68 patients received intravenous thrombolysis with alteplase as the treat-ment group, 59 patients did not receive intravenous thrombolytic therapy as the control group. The incidence of intracerebral hemorrhage and mortality were observed in the two groups after thrombolytic therapy. Their nerve function defect was scored according to the NIHSS scores before and after treatment at day 7 and day 30. Their living ability was assessed by mRS in modified Rankin chart after the treatment at the day 90. Results The NIHSS scores were significant lower in the 2 groups after therapy (P 0.05). Conclusion Intravenous rt-PA thrombolytic therapy is effective and safe for AIS whose NIHSS scores are more than 15 points and onset time are less than 4.5 h.

ABSTRACT

Introducción: La incidencia de trombos cardíacos en recién nacidos (RN) ha aumentado con el uso de catéteres venosos centrales. La trombólisis con activador del plasminógeno tisular recombinante (rTPA) se ha utilizado como alternativa a la heparina en trombos gigantes con riesgo vital y de embolización. Nuestro objetivo fue describir la respuesta y las complicaciones relacionadas con el uso del rTPA en el manejo de trombos cardíacos con riesgo vital en RN. Pacientes y método: Estudio retrospectivo de 8 RN, 7 prematuros, con trombos cardíacos en los cuales se utilizó rTPA. Se analizó la edad gestacional y al diagnóstico, peso, sexo, enfermedades asociadas, hemograma, niveles de fibrinógeno, dímero D, tiempo parcial de tromboplastina activada y de protrombina, antes y al término de la infusión de rTPA. El diagnóstico del trombo se realizó por ecocardiografía doppler. La indicación de rTPA fue trombo mayor de 10 mm o que ocupara más del 50% de la cavidad donde se localizaba; aumento del tamaño a pesar del tratamiento con heparina, aspecto fragmentado y lobulado con riesgo embólico pulmonar o sistémico o que comprometiera la función valvular o cardíaca. Resultados: Cuatro hombres; peso promedio de 1.580 g. La principal enfermedad fue la sepsis (7/8), se usó catéter venoso central en todos, la vena cava superior fue la localización más frecuente, con tiempo promedio de instalación previo al diagnóstico de 12 días. En 7/8 RN los trombos se ubicaron en la aurícula derecha, con un tamaño entre 7 a 20 mm. Tres pacientes recibieron heparina de bajo peso molecular previo al uso de rTPA, se realizaron entre uno a 5 ciclos con rTPA. En 4 pacientes se logró resolución completa del trombo a los 3,5 días en promedio. No hubo embolia ni fallecidos. Cuatro pacientes presentaron hemorragia intracraneana grado I, sin secuelas en el seguimiento. Conclusión: Este estudio constituye la primera serie de neonatos tratados con rTPA en Chile, lográndose la resolución completa del trombo en un 50% de los RN y parcial en el resto, permitiendo con ello disminuir el riesgo vital secundario a este proceso patológico.


Introduction: The incidence of cardiac thrombi in newborns has increased with the use of central venous catheters. Thrombolysis with recombinant tissue plasminogen activator (rTPA) has been used as an alternative to heparin in life threatening giant thrombus and embolization. The aim of this study is to describe the response and complications related to the use of rTPA in the management of life- threatening cardiac thrombi in newborns. Patients and method: The medical records of 8 newborn were reviewed in a retrospective study, of whom 7 were preterm with cardiac thrombi, and rTPA was used in all of them. Results: The patients included 4 males with a mean weight of 1580 gr. The principal pathology was sepsis (7/8), all of them used venous central catheter. The superior vena cava was the most frequent location, with a mean time of installation before the diagnosis of 12 days. RN 7/8 thrombi were located in the right atrium with a size between 7 to 20 mm. Three patients received low molecular weight heparin prior to using rTPA. They received between 1 to 5 cycles with rTPA. In 4 patients complete resolution of the thrombus was achieved in a mean of 3.5 days. Four patients had intracranial haemorrhage grade I, without sequelae at follow-up. There were no deaths or embolism. Conclusion: This study is the first series of infants treated with rTPA in Chile, and where its use has quickly achieved complete resolution of the thrombus in 50% of cases, and partially in the others, thus reducing the secondary life-threatening risk of this disease.

ABSTRACT

Objective To compare the efficacy and safety of intravenous thrombolysis on cardiogenic cerebral infarction and noncardiac infarction by recombinant tissue plasminogen activator (rt-PA). Methods Comparations of NIHSS, mRS and adverse events before and after treatment were made between the cardiogenic group and the noncardiac group. Results No significant differences in the NIHSS and mRS were found between the two groups. The incidence of brain hernia and dermatorrhagia in the cardiogenic group was higher than that in the noncardiac group. Conclusion Rt-PA therapy in cardiogenic cerebral infarction was effective and safe in spite of higher incidence of hemorrhage and brain hernia.

ABSTRACT

Objective To explore different doses of recombinant tissue-type plasminogen activator (rt-PA) intravenous thrombolytic therapy for acute cerebral infarction.Methods 130 patients with acute cerebral infarction were as the research subjects selected from May 2014 to May 2015 for rt-PA thrombolytic therapy, who were divided into two groups according to rt-PA thrombolytic agent dose, 65 cases in each group.Evaluated the clinical efficacy of thrombolytic therapy after treatment in accordance within 24 h intracerebral hemorrhage (ICH) , symptomatic intracerebral hemorrhage (SICH) , other bleeding symptoms and for 3 months after treatment the prognosis was good rate, total mortality.For pre-treatment, the degree of defect nerve function after two groups of patients were scored by NIHSS score, correlation analysis between the two groups of clinical efficacy and function of the degree of nerve defect before treatment.Results 3 months after thrombolysis total mortality in the standard dose group was significantly higher than that in the low-dose group (P<0.05) .After treatment, both groups NIHSS scores were significantly lower than before treatment (P<0.05); After treatment, NIHSS score 4-8 points in the proportion of low-dose group was significantly more than that in the standard dose group (P<0.05); NIHSS score 9-16 points, 17-24 points in the proportion of low-dose group were significantly less than that in the standard dose group (P<0.05).NIHSS9-16 points of patients after total mortality three months in the standard-dose group was significantly higher than that in the low-dose group (P<0.05) . Conclusion Different doses of rt-PA thrombolytic therapy in acute cerebral infarction are basically the same, and the degree of neurological deficit does not affect the efficacy, but reduce mortality in patients 3 months after low-dose rt-PA treatment, it is worth widely used in clinical practice.

ABSTRACT

<b>Introduction</b> : Intravenous rt-PA therapy for acute ischemic stroke patients within 4.5 hours after onset is approved and effective, but is difficult to implement in depopulated areas because of geographical conditions and lack of medical specialists.<br><b>Methods</b> : From February 2013 to February 2014, 75 acute ischemic stroke patients were transferred to our hospital, four (5.3%) of which were subjected to the “drip and ship” method of rt-PA infusion using a telemedicine system for emergency medicine (k-support). We examined the time course after onset and the treatment outcome of these four cases<br><b>Results</b> : Four cases had rt-PA infusion started in the depopulated area. ln one case, recanalization of occluded vessels was demonstrated resulting in improved clinical symptoms. <br><b>Conclusion</b> : The “drip and ship” method of rt-PA infusion using a telemedicine system for emergency medicine (k-support) may be a safe and ideal treatment in depopulated areas.
