During the COVID-19 pandemic period, the technological and resource availability for the care of these patients with thrombotic disease is critical, marking a factor of morbidity and poor prognosis in these cases. We describe a case of priapism in a patient with COVID-19, during the course of systemic inflammatory response syndrome and respiratory distress syndrome with a procoagulant state, seeking to relate the pathophysiological factors of ischemic priapism in patients with infection with SARS-Cov-2 SARS-Cov-2 is generated by a single-stranded RNA Coronavirus that enters human cells mainly by binding to angiotensin-converting enzyme 2, which is highly ex-pressed in pulmonary alveolar cells, myocytes, and vascular endothelium, with primary transmission medium, after inhaling the viral particles, the respiratory tract [1] . It is associated with alterations in D dimer, fibrin degradation products, and prothrombin time prolongation, with hemostatic changes in these factors that indicate some form of coagulopathy that predisposes thrombotic events; however, it is still unknown whether these changes occur in response to a direct effect of SARS-Cov-2 or are a direct consequence of the cytokine storm, precipitated by the systemic inflammatory response syndrome, observed in this viral infection [2] . Some publications have commented on the complication of pulmonary thromboembolism in patients with COVID in 25-31% of those admitted to the ICU, with a dichotomous association on the antithrombotic prophylaxis [3, 4] . The first apparent case of ischemic priapism, related to SARS-Cov-2, is also described, mainly associating the state of hypercoagulability as a pathophysiological mechanism [5] . Veno-occlusive priapism is a compartment syndrome of the penis, in which an initial occlusion of the efferent venous flow occurs and a subsequent arrest of the afferent arterial flow, with a pathophysiology not yet understood, with multifactorial mechanisms that involve alterations in the cavernous microenvironment, smooth muscle dysregulation; leading to venous stasis, in addition to condi-2 DOI: 10.1159/000514421 tions that increase blood viscosity [6] ; with failure to achieve detumescence, associated with progressive fibrosis of the cavernous tissue and erectile dysfunction from 48 h of the ischemic course and association of 90% of erectile dysfunction after 24 h of low-flow priapism [7] . To date, there is only one reported case of priapism with SARS-Cov-2 infection, so it is relevant to provide data in the medical literature about the presentation of this disease with an emerging causal factor SARS-COV-2. A 39-year-old man with no history, overweight, presents 8 days of myalgia, diarrheal stools, abdominal pain, and fever; they are managed with trimethoprim sulfamethoxazole, later the clinical course of dry cough and dyspnea on medium efforts is followed, for which he is taken to the emergency service, where he is admitted with tachycardia, fever, with signs of respiratory distress, desaturation and oxygen requirements of high flow, document oxygenation disorder with Pa/FiO 2 170 (Table 1) , in the chest highresolution tomography they identify multiple areas of alveolar consolidation and patched ground glass in both lung fields with the presence of consolidative processes predominantly in the lower lobes; given the strong suspicion of SARS-Cov-2 infection, they indicated transfer to the intermediate care unit, started parenteral corticosteroids, thromboprophylaxis with LMWH, and antibiotic coverage with ampicillin sulbactam and clarithromycin. After 2 days of vigil pronation, for deterioration in the levels of oxygenation, he presents hypoxemic respiratory failure with Pa/FiO 2 56, is intubated and ventilated, after receiving propofol, midazolam, fentanyl, without having a muscle relaxant. At 24 h after clinical deterioration and requirement for ventilatory management and pronation cycles, he presented sustained penile erection for >4 h, they placed local measures without response, for which they performed intracavernous application of adrenaline without achieving detumescence. Urology evaluates at 72 h finding a tumescent penis at its base, a lower proportion in the distal penile region, flaccid glans, and ecchymosis on puncture areas, derived with a urethral catheter (Fig. 1) , given the expected prognosis in recovery of function erectile after 72 h of onset of the symptoms and the unfavorable pulmonary course, proceed with expectant management; the hypothesis of low-flow ischemic priapism was confirmed with penile doppler, with absence of flow at the level of the bilateral cavernous arteries, fibrotic plaques in the left corpus cavernosum without arteriocavenous fistulas 10 days after the onset of the condition. Later, he presented a tachyarrhythmia that required electrical and pharmacological cardioversion, associated with AKIN III kidney failure with renal replacement therapy, finally the patient died after a syndrome of multi-organ dysfunction, with refractory shock and sustained oxygenation disorder, after 17 days in the unit intensive care. SARS-Cov-2 virus infection is confirmed by PCR. Priapism includes an erection sustained for more than 4 h, painful, related or not to sexual activity; the 3 main subtypes of priapism are ischemic, nonischemic, and re- current; the first being the one with the highest presentation in 95% of the episodes, and since it is considered a compartment syndrome; its intervention is a medical emergency. In patients with SARS-Cov-2 infection, dimero D elevations and CID occur, related to endothelial dysregulation and endothelial dysfunction; being the probable underlying pathophysiology, yet to be elucidated in future studies [8] [9] [10] . These factors are associated with a prothrombotic state, which could be related to the obstruction of the small emissary veins of the subtunical space [11] . In our patient, the clinical presentation and penile doppler findings allow the diagnosis of ischemic priapism to be made, and although the presentation of the condition is related to the causal factors of a prothrombotic state, given by the elevation of dimero D, leukocytosis, elevation of CRP and LDH, as well as a condition of nonmodulated inflammation that could argue the cause of priapism, we found a distracting factor and it is the infusion of propofol 24 h before the onset of erection, described in different case reports as the cause of presentation of ischemic priapism, in anesthetic inductions with parenteral or epidural use, by blocking the sympathetic system and influencing smooth muscle relaxation [12, 13] . Although he was on prophylactic anticoagulation, a phenomenon of resistance to heparins has been described in patients with SARS-Cov-2, associated with elevated levels of Factor VIII, fibrinogen, and D dimer [14, 15] . The clinical presentation of priapism related to SARS-Cov-2 infection has been described to date only by a case report, with pathophysiological bases still, to be elucidated in future studies, in our patient, we have an important association but with an external factor which does not allow to affirm that SARS-Cov-2 is a cause of ischemic priapism.
