Hematoma retroperitoneal espontáneo en pacientes con neumonía grave por SARS-CoV-2 / Spontaneous retroperitoneal hematoma in patients with severe SARS-CoV-2 pneumonia

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)

Spontaneous retroperitoneal hematoma: a case report.

BACKGROUND: Spontaneous retroperitoneal hematoma is defined as bleeding in the retroperitoneal space without any triggers such as trauma, invasive procedures, and abdominal aortic aneurysm. CASE PRESENTATION: A 48-year-old Japanese man who experienced sudden abdominal pain, severe hypotension, and decreased hemoglobin was diagnosed with spontaneous retroperitoneal hematoma. Contrast-enhanced computed tomography revealed massive left retroperitoneal hematoma; however, neither extravasation nor causative aneurysm was noted. Through conservative management with close monitoring, he was treated and discharged on the tenth hospital day without any morbidity. CONCLUSIONS: Spontaneous retroperitoneal hematoma treatment comprises conservative management, transcatheter arterial embolization, and surgical intervention. The mortality rate of spontaneous retroperitoneal hematoma is so high that the optimal treatment timing needs to be carefully judged on the basis of detailed evaluation, and management algorithm with clear criteria.

Spontaneous Left External Iliac Vein Rupture.

Spontaneous rupture of the Iliac Vein is very rare in practice. In over 90% of cases, the venous lesion is located on the left side. The exact etiology of this condition is unknown. Spontaneous injury of the iliac vein is thought to be favored by intense exercise, constipation, cough, labor, May-Thurner syndrome or pre-existing inflammatory changes in the venous wall are also implicated. We present the case of an 83-year-old woman who is brought to the Emergency Department for abdominal pain located in the left flank and in the left iliac fossa, which appeared after a medium physical exertion. After an emergency contrast-enhanced abdominal CT scan, the diagnosis of spontaneous rupture of the left external iliac vein is established. Surgery is performed with extreme urgency by retroperitoneal approach and due to the very precarious condition of the patient, venous ligation is done, wishing to perform a Palma-Dale venous bypass at a later time. Although a rare cause of spontaneous retroperitoneal hematoma, a non-traumatic rupture of the common or external iliac vein should be considered in patients in shock with massive retroperitoneal bleeding, accompanied by a high mortality rate.

Spontaneous retroperitoneal hematoma induced by vitamin K antagonist therapy: A case report.

Vitamin K antagonists (VKA) are recommended in patients with mechanical heart valves. Major bleeding events remain the most life-threatening complication of this therapy and sometimes it can occur in unusual anatomic areas. Spontaneous retroperitoneal hematoma is one of the rare complications of anticoagulation therapy, which needs to be recognized early and managed promptly. Here, we report a case of a 40-year-old woman with mechanical heart valve treated with acenocoumarol, who was admitted to the emergency department with abdominal pain and whose investigations came back in favor of a massive retroperitoneal hematoma. The patient was successfully treated through conservative management resulting in a good outcome. Clinicians should be careful when prescribing VKA and should always think of retroperitoneal bleeding in the event of abdominal pain or a sudden decrease in the hemoglobin levels of anticoagulated patients.

Spontaneous Retroperitoneal Hematoma Presenting as Femoral Neuropathy in a Patient on Low Molecular Weight Heparin Therapy.

INTRODUCTION: Retroperitoneal hemorrhage has been sparsely reported with warfarin therapy. In this paper, we describe a case of spontaneous retroperitoneal hematoma causing femoral neuropathy following treatment with low molecular weight heparin. CASE REPORT: A 65-year-old gentleman had presented with acute onset left-sided thigh pain, paraesthesia, and weakness along with lower backache. On deeper introspection, our patient had, in the recent past, been thrombolyzed for pulmonary embolism. The clinical examination led us to suspect an acute lumbar pathology, and he was investigated on those lines. Imaging studies, however, revealed a massive retroperitoneal hemorrhage which was the cause of femoral neuropathy. In this case report, the presentation of this rare association has been discussed with special emphasis on clinical premonition in the background of anticoagulant therapy. Watchful and medical treatment yielded successful recovery at follow-up. CONCLUSION: Cautious clinical assessment is needed in patients taking anticoagulant therapy. The presentation of a femoral neuropathy is often intriguing. Management options include careful observation and emergency decompression in cases of worsening neurological status.

Hematoma retroperitoneal espontáneo concurrente con una atonía uterina poscesárea / Concurrent Spontaneous Retroperitoneal Hematoma with Uterine Atony Post Cesarean

El hematoma retroperitoneal espontáneo durante el embarazo es una complicación infrecuente definido como el sangrado en el espacio retroperitoneal que ocurre sin historia de trauma reciente, tratamiento anticoagulante o enfermedad vascular. El objetivo del trabajo es presentar un caso grave poco usual en que el hematoma retroperitoneal coexistió en una paciente con atonía uterina. Se presenta una gestante de 21 años y 39 semanas que acudió al Cuerpo de Guardia del Hospital Ginecobstétrico de Guanabacoa en noviembre 2016 por presentar dolor abdominal. Se ingresa en Cuidados perinatales. Los exámenes complementarios, físico y la cardiotocografía fueron normales. Cuatro horas después aqueja dolor lumbar y se detectó dolor a la palpación en región intercostal posterior derecha sin otro hallazgo ni alteraciones hemodinámicas. No hay dinámica uterina y frecuencia fetal 140 latidos/minuto. Dos horas después, presentó un cuadro que el familiar informa como una "convulsión", no observada por personal médico o de enfermería. No hay toma de conciencia y los signos vitales normales, se comprueba una bradicardia fetal que motiva la indicación de cesárea de urgencia. La hemoglobina descendió a 70 g/L. Se repone volumen y se extrae un neonato con Apgar 1-3. Se produce atonía uterina que no cedió al tratamiento medicamentoso y/o masaje. Se realiza técnica de B- Lynch para la hemostasia que se logra. Se comprueba hematoma retroperitoneal no activo desde borde superior hepático hasta flanco derecho. Se estabiliza hemodinámicamente. El neonato fallece a las 72 horas. El diagnóstico y tratamiento precoz del hematoma retroperitoneal contribuye a disminuir la morbilidad y mortalidad materna.

Spontaneous retroperitoneal hematoma during pregnancy is an uncommon complication defined as bleeding in the retroperitoneal space that occurs without a history of recent trauma, anticoagulant treatment or vascular disease. The objective of this study is to present an unusual case in which the retroperitoneal hematoma coexisted in a patient with uterine atony. A 21 year old pregnant woman of 39 weeks who went to the Emergency Room at Guanabacoa Gynecobstetric Hospital in November 2016, due to abdominal pain. The patient is admitted to perinatal care. Complementary studies and physical examination were normal, including cardiotocography. Four hours later, she suffered back pain, which was detected on palpation in the right posterior intercostal region without any other finding or hemodynamic changes. There were no uterine dynamics and fetal frequency was 140 beats / minute. Two hours later, this patient presented a "seizure," according to her family member that was not observed by medical or nursing staff. There was no loss of consciousness and her vital signs were normal. A fetal bradycardia is verified that motivates the indication of emergency caesarean section. Hemoglobin decreased to 70 g / L. Volume was replaced and an Apgar 1-3 neonate was extracted. There was uterine atony that did not yield to drug treatment and massage. The B-Lynch technique was performed for the hemostasis that was achieved. A non-active retroperitoneal hematoma was found from the superior border of the liver to the right flank. The patient was hemodynamically stabilized. The neonate died at 72 hours. The diagnosis and early treatment of retroperitoneal hematoma help to reduce maternal morbidity and mortality.

Three cases of spontaneous lumbar artery rupture in hemodialysis patients.

We encountered three cases of retroperitoneal hematoma caused by spontaneous lumbar artery rupture, a rare vascular complication. At the time of retroperitoneal hematoma, two patients were on anticoagulant/antiplatelet therapy. One patient was not taking any anticoagulant/antiplatelet agents but was receiving hemodialysis treatment with heparin. Lumbar artery rupture was successfully controlled by transcatheter arterial embolization in all patients, but one patient developed multiple organ failure and died. We suggest that spontaneous lumbar artery rupture may occur in patients being treated with maintenance hemodialysis or anticoagulant/antiplatelet therapy. Therefore, clinicians should suspect lumbar artery rupture in patients with unstable vital signs and rapid onset of anemia because early diagnosis and appropriate intervention are necessary to decrease the risks of morbidity and mortality.

Abdominal Compartment Syndrome Due to Spontaneous Retroperitoneal Hemorrhage in a Patient Undergoing Anticoagulation

Spontaneous retroperitoneal hemorrhage is one of the most serious and often lethal complications of anticoagulation therapy. The clinical symptoms vary from femoral neuropathy to abdominal compartment syndrome or fatal hypovolemic shock. Of these symptoms, abdominal compartment syndrome is the most serious of all, because it leads to anuria, worsening of renal failure, a decrease in cardiac output, respiratory failure, and intestinal ischemia. We report a case of a spontaneous retroperitoneal hemorrhage in a 48-year-old female who had been receiving warfarin and aspirin for her artificial aortic valve. She presented with a sudden onset of lower abdominal pain, dizziness and a palpable abdominal mass after prolonged straining to defecate. Computed tomography demonstrated a huge retroperitoneal hematoma and active bleeding from the right internal iliac artery. After achieving successful bleeding control with transcatheter arterial embolization, surgical decompression of the hematoma was performed for management of the femoral neuropathy and the abdominal compartment syndrome. She recovered without any complications. We suggest that initial hemostasis by transcatheter arterial embolization followed by surgical decompression of hematoma is a safe, effective treatment method for a spontaneous retroperitoneal hemorrhage complicated with intractable pain, femoral neuropathy, or abdominal compartment syndrome.

Spontaneous Retroperitoneal Hematoma due to Liver Cirrhosis: A Case Report / 대한간학회지

Spontaneous retroperitoneal hemorrhage due to liver cirhosis associated with impaired coagulopathy is very rare disease. Spontaneous retroperitoneal hemorrhage has been recorded as having originated from many retroperitoneal organs and blood vessels, and it may be due to local disease and/or systemic factors. In the majority of patients the bleeding arose from the kidney or adrenal gland. Among the systemic causes of spontaneous retroperitoneal hemorrhage are anticoagulation therapy and chronic hemodialysis during the course of which hemorrhagic complications may occur at many site, including the retroperitoneal space. Blood dyscrasias have been a rare cause of spontaneous retroperitoneal hemorrhage. Conditions reported have been included hemophilia, leukemia, polycythemia and sickle cell trait. Virtually every hemostatic function may be impaired in patients with severe hepatic disease as the result of failure of both the biosynthetic and clearence function of the liver, thrombocytopenia, platelet dysfunction, intravascular coagulation and fibrinogenolysis, and the effects of products of fibrinogen catabolism on the coagulation mechanism. We are reporting a case of spontaneous retroperitoneal hematoma in a patient with alcoholic liver cirrhosis with brief review of literature.
