RESUMO
Objective: A growing proportion of patients with chronic limb threatening ischaemia (CLTI) are elderly, the most challenging for management decisions. The aim was to study the patient profile and outcome of CLTI in octogenarian patients, comparing them with younger patients. Methods: Retrospective cohort of consecutive patients hospitalised for CLTI with infrainguinal disease in a Spanish centre (2013-2020). Data on age, comorbidity, anatomical characteristics, and treatment were gathered. Patients were stratified according to age (<80 and ≥80 years). The primary outcomes were overall survival and limb salvage (LS), analysed using Kaplan-Meier and Cox regression. Results: : A total of 512 patients were enrolled: 305 were <80 years old with mean age 69.7 ± standard deviation (SD) 8.2 years, and 207 were ≥80 years old with mean age 85.3 ± SD 3.6 years. Smoking and diabetes mellitus were more frequent in younger patients (78.0% vs. 45.4%, p < .001; 68.5% vs. 59.5%, p = .037 respectively). Older patients had a higher prevalence of heart and kidney disease (70.5% vs. 57.0%, p = .002; 39.6% vs. 24.3%, p < .001, respectively). The arterial disease was femoropopliteal or tibial in 68.9% and 31.1% in patients <80 years and 58.9% and 41.1% in patients ≥80 years (p = .021). In younger patients, conservative treatment was indicated in 18.0%, endovascular treatment (ET) in 41.6%, and open or hybrid surgery (OS) in 40.3%; in patients ≥80 years these were 36.9%, 37.4%, and 25.7%, respectively (p <. 001). Mean follow up was 23.3 ± SD 17.4 months. One and two year overall survival was 85.4% and 73.0% in younger patients and 64.1% and 51.3% in patients ≥80 years (p < .001). LS was 83.7% and 79% at the same times in younger patients and 75.3% and 72.1% in older ones (p = .045). In younger patients ET led to worse LS than OS (p = .005) but not in older patients (p = .29). Conclusion: Patients ≥80 years with CLTI have higher comorbidity and lower life expectancy and receive conservative treatment more frequently than younger patients. ET and OS are associated with similar survival and LS in these older patients.
RESUMO
Recientemente se han publicado varios casos de hematomas retroperitoneales espontáneos (Hre) en el contextode infección por SarS-CoV-2. este estudio presenta una revisión sistemática de la literatura con el objetivo deprofundizar en esta infrecuente asociación. Se identificaron 32 casos de Hre, el 28,1 % con enfermedad COVID-19 crítica. el 68,7 % recibió anticoagulacióncon HBpM y el 15,6 % con heparina sódica. La mediana de días hasta el diagnóstico fue de 10,5 (rango de 0-38).en el 31,2 % de los casos se optó por manejo conservador, mientras que otro 31,2 % requirió angioembolización. Se comunicaron 10 exitus (31,2 %), 6 probablemente relacionados con el Hre.existen hipótesis acerca de la relación entre la infección por SarS-CoV-2 y los fenómenos hemorrágicos. Se handescrito dos mecanismos que explicarían la coagulopatía: la unión al receptor aCe2 y la acción directa del virussobre el endotelio vascular. Por otra parte, la disfunción plaquetaria, la trombocitopenia inmune y la respuesta alSIrS, así como los microtraumas secundarios al esfuerzo tusígeno, la ventilación mecánica invasiva o los cambiosposturales, sugieren un origen multicausal del Hre.La literatura sobre esta asociación es escasa. Dado el exceso de morbimortalidad que supone, se considera nece-sario profundizar en su investigación.(AU)
Recently, cases of spontaneous retroperitoneal haematomas (SrH) in the context of SarS-CoV-2 infection havebeen published. this study presents a systematic review with the aim of further investigating this rare association. Thirty-two cases were identified, with a 28,1 % of critical patients. a total of 68,7 % received anticoagulation withLMWH, and a 15,6 % with UFH. the median number of days to diagnosis was 10,5 (0-38). Conservative manage-ment was chosen in 31,2 %, while another 31,2 % required angio-embolisation. ten exitus (31,2 %) were reported,6 related to SrH. There are hypotheses on the link between SarS-CoV-2 infection and haemorrhagic phenomena. two mechanismshave been described that would explain coagulopathy: the binding of SarS-CoV-2 to the aCe2 receptor and itsdirect action on the vascular endothelium. Furthermore, the platelet dysfunction, immune thrombocytopenia andSIrS, added to the endothelial disruption in retroperitoneal vessels, as well as microtrauma secondary to coughstress, invasive mechanical ventilation and/or postural changes, suggest a multicausal origin of SrH. The literature concerning this association is scarce. Given the excess morbidity and mortality involved, it is consid-ered necessary to investigate it further.(AU)
