Severe case of postpartum-acquired haemophilia A after laparoscopic cholecystectomy.

Acquired factor VIII inhibitor, also known as acquired haemophilia A, has been associated with the postpartum state in young females. Treatment of acquired haemophilia A is focused on two goals: control of bleeding and eliminating the factor VIII inhibitor. Management requires successful intervention to accomplish both goals. Here, we describe the presentation and management of a case of acquired haemophilia A resulting in particularly severe and protracted intra-abdominal bleeding after routine laparoscopic cholecystectomy in a young and otherwise healthy female at 3 months postpartum. Due to diffuse intra-abdominal bleeding, she required return to the operating room on five occasions for intra-abdominal packing, reassessment of bleeding and ultimate fascial closure. Her abdomen was open for 5 days. She was treated with activated recombinant human factor VIIa to bypass inhibited factor VIII, and with immunosuppression using steroids, cyclophosphamide and anti-CD20 monoclonal antibody rituximab. She achieved remission after 6 weeks of treatment.

Retrospective evaluation of admission total plasma protein as a predictor of red blood cell transfusion requirement in dogs diagnosed with traumatic and nontraumatic hemoabdomen: 90 dogs (2009-2019).

OBJECTIVE: To evaluate the association of admission total plasma protein (TPP) and the administration of red blood cell transfusions in dogs with diagnosed hemoabdomen. To secondarily evaluate additional point-of-care parameters associated with red blood cell transfusion administration. DESIGN: Retrospective study between 2009 and 2019. SETTING: University veterinary teaching hospital. ANIMALS: Ninety dogs admitted to a university veterinary teaching hospital after a diagnosis of traumatic or nontraumatic hemoabdomen (NTH). MEASUREMENTS AND MAIN RESULTS: Medical records were retrospectively reviewed; signalment, point-of-care diagnostics, and transfusion administration information was recorded. A total of 47 dogs (traumatic hemoabdomen 11/26; NTH 36/64) received packed red blood cell transfusions. For each 1 g/dL unit decrease in TPP, dogs had an increased odds ratio (OR) of 2.14 (95% confidence interval [CI]: 1.44-3.40, P < 0.001) of receiving a red blood cell transfusion. Dogs diagnosed with NTH were more likely to receive a red blood cell transfusion than dogs with a traumatic hemoabdomen (OR: 2.78, 95% CI: 1.11-7.141, P = 0.03). Lower PCV values (OR: 1.08, 95% CI: 1.04-1.12, P < 0.001), bicarbonate values (OR: 1.3, 95% CI: 1.09-1.56, P = 0.003), and base excess (OR: 1.27, 95% CI: 1.1-1.49, P = 0.003) were associated with a higher likelihood of red blood cell transfusion. Additionally, higher lactate (OR: 1.35, 95% CI: 1.16-1.63, P < 0.001) and Acute Patient Physiologic and Laboratory Evaluation (APPLE)fast scores (OR: 1.10, 95% CI: 1.04-1.17, P < 0.001) were associated with increased red blood cell transfusion administration. CONCLUSIONS: Low admission TPP, independent of low PCV, was associated with red blood cell transfusions regardless of underlying cause. For each 1 g/dL unit decrease in TPP on presentation, dogs were approximately 2 times more likely to receive a red blood cell transfusion during hospitalization. Other factors that were associated with increased transfusion administration included presenting PCV, PCV/TPP ratio, bicarbonate, base excess, lactate, and APPLEfast scores.

Hemoperitoneum after a Bothrops snakebite: Case report.

Snakebites are frequent in tropical countries. Brazil has an average of 27,000 cases per year, with a fatality rate of 0.5%, and the Bothrops genus is the most common causative agent, accounting for about 70-90% of the accidents. This report describes a case of human envenomation by a juvenile Bothrops jararaca snake in São Paulo, Brazil, in a 71 years-old man, previously healthy. He presented a life-threatening envenomation, which developed to severe hypotension, acute kidney injury and extensive peritoneal hemorrhage. The hemoperitoneum was diagnosed due to persistent hypotension associated with anemia, pain and gastrointestinal complaints. Abdominal Computed Tomography scans showed a moderate to large amount of presumable hematic material inside the abdominal cavity, predominantly in the perihepatic and perisplenic spaces. The intra-abdominal hemorrhage was not surgically addressed, and the patient was discharged 5 days after hospitalization, with the progressive absorption of the hemoperitoneum. Systemic bleeding is one of the complications and main causes of death in Bothrops envenomations. Acute peritoneal hemorrhage is one of these serious complications that must be carefully addressed since its management must take into account the risk of bleeding caused by toxins that affect hemostasis. The case described highlights the importance of early diagnosis and adequate management of this potentially fatal complication in snakebites.

Haemoperitoneum due to ovarian rupture after oocyte retrieval procedure.

Transvaginal ultrasound-guided oocyte retrieval is the gold-standard technique for oocyte retrieval that has few associated procedural and post-procedural complications. Rarely, severe complications can occur including haemoperitoneum, for which the incidence reported in the literature is approximately 0.08-0.22%. In this report, we present the case of a nulliparous woman in her late 30s who presented to the hospital with severe abdominal pain following transvaginal ultrasound-guided oocyte retrieval and was found to have extensive haemoperitoneum attributed to ovarian rupture.

TEG-based transfusion protocol is associated with decreased blood product use without increased risk of hemoperitoneum.

BACKGROUND: Thromboelastography (TEG) informs the need for blood product transfusions to prevent procedural bleeding complications in patients with cirrhosis. We aimed to evaluate the impact of using a TEG-based transfusion protocol on blood product utilization before paracentesis and the post-paracentesis hemoperitoneum (PPH) incidence. METHODS: We conducted an ambispective analysis of patients with cirrhosis who underwent paracentesis from 2017 to 2021. In May 2019, we enacted a TEG-based transfusion protocol to guide pre-paracentesis blood product use. Patients with platelets < 20,000 or international normalized ratio ≥ 4 underwent TEG and received blood products if r value > 10 min or MA <30 mm. Patients were divided into pre-TEG and post-TEG protocol cohorts based on the date of paracentesis. Pre-paracentesis blood product transfusions in the form of platelets, fresh frozen plasma, and cryoprecipitates were recorded. PPH was defined as a decrease in hemoglobin of ≥1 g and the presence of blood on diagnostic imaging and/or the need for therapeutic intervention. RESULTS: A total of 483 patients underwent 1281 paracenteses. The main etiologies of cirrhosis were alcohol (43%) and NASH (25%), and the mean MELD-sodium was 22±6. Pre-TEG and post-TEG protocol cohort sizes were similar: 253 patients and 607 paracenteses versus 230 patients and 674 paracenteses. After TEG-protocol implementation, blood product transfusions decreased significantly (228 vs. 49 products, p<0.001) with associated cost savings. One patient in each cohort developed PPH. CONCLUSION: Implementation of a pre-paracentesis TEG-based transfusion protocol for patients with cirrhosis successfully resulted in decreased blood product use with no associated increase in incidence of PPH.

Ultrasonography in thoracic and abdominal stab wound injury: results from the FETTHA study.

BACKGROUND: While the role of Extended Focused Assessment with Sonography in Trauma (eFAST) is well defined in the management of severe blunt trauma, its performance in injuries caused by stab wounds has been poorly assessed. METHODS: Prospective single centre study which included all patients with stab wounds to the thorax or abdomen between December 2016 and December 2018. All patients underwent initial investigation with both eFAST and CT scan, except in cases of haemodynamic or respiratory instability, and in cases with a positive diagnosis by eFAST in which case surgery without CT scan was performed. RESULTS: Of the 200 consecutive patients included, 14 unstable patients underwent surgery immediately after eFAST. In these 14 patients, 9 had cardiac tamponade identified by eFAST and all were confirmed by surgery. In the remaining 186 patients, the median time between eFAST and CT scan was 30 min (IQR 20-49 min). Test characteristics (including 95% CI) for eFAST compared with reference standard of CT scan for detecting pneumothorax were as follows: sensitivity 77% (54%-92%), specificity 93% (90%-97%), positive predictive value (PPV) 60% (49%-83%), negative predictive value (NPV) 97% (93%-99%). Test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemothorax were as follows: sensitivity 97% (74%-99%), specificity 96% (92%-98%), PPV 83% (63%-93%) and NPV 99% (96%-100%). Finally, test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemoperitoneum were as follows: sensitivity 75% (35%-97%), specificity 97% (93%-99%), PPV 55% (23%-83%) and NPV 99% (96%-99%). CONCLUSIONS: In patients admitted with stab wounds to the torso, eFAST was not sensitive enough to diagnose pneumothorax and haemoperitoneum, but performed better in the detection of cardiac tamponade and haemothorax than the other injuries. More robust multicentre studies are needed to better define the role of eFAST in this specific population.

Bleeding hepatocellular adenoma: historical series and outcomes.

INTRODUCTION: hepatocellular adenoma - AHC - is a rare benign neoplasm of the liver more prevalent in women at reproductive age and its main complication is hemorrhage. In the literature, case series addressing this complication are limited. METHODS: between 2010 and 2022, 12 cases of bleeding AHC were attended in a high-complexity university hospital in southern Brazil, whose medical records were retrospectively evaluated. RESULTS: all patients were female, with a mean age of 32 years and a BMI of 33kg/m2. The use of oral contraceptives was identified in half of the sample and also half of the patients had a single lesion. The mean diameter of the largest lesion was 9.60cm and the largest lesion was responsible for bleeding in all cases. The presence of hemoperitoneum was documented in 33% of the patients and their age was significantly higher than the patients who did not have hemoperitoneum - 38 vs 30 years, respectively. Surgical resection of the bleeding lesion was performed in 50% of the patients and the median number of days between bleeding and resection was 27 days. In only one case, embolization was used. The relation between ingrowth of the lesions and the time, in months, was not obtained in this study. CONCLUSION: it is concluded that the bleeding AHC of the present series shows epidemiological agreement with the literature and may suggest that older patients trend to have hemoperitoneum more frequently, a fact that should be investigated in further studies.

Rapid resolution of hyperfibrinolysis in dogs with spontaneous hemoperitoneum following surgical control of hemorrhage.

OBJECTIVE: To estimate the point prevalence and duration of hyperfibrinolysis (HF) in dogs undergoing surgical control of spontaneous hemoperitoneum (SHP). DESIGN: Prospective observational study. SETTING: Single veterinary teaching hospital. ANIMALS: Forty-five client-owned dogs with SHP were screened for HF. Eighteen HF dogs treated surgically were studied. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Dogs with SHP and evidence of shock admitted for surgical control of hemorrhage were screened for HF. Blood samples were collected for PCV, total plasma protein, platelet count, and thromboelastography with 50 U/mL of tissue plasminogen activator at presentation and every 8 hours postoperatively until 72 hours, discharge, or death. HF was defined as a tissue plasminogen activator-activated thromboelastography lysis percentage measured 30 minutes after maximum amplitude (LY30) of ≥20%. LY30 values were compared to a cohort of samples obtained from healthy dogs (n = 22). The point prevalence of HF in all dogs screened was 40% (18/45 dogs), and the mean LY30 at baseline for HF dogs was 48.9% (±24.2%), which was significantly higher than that of control dogs (4.8% ± 7.1%, P < 0.001) and non-HF dogs (1.9% ± 5.7%, P < 0.001). In HF dogs, there was a significant decrease in LY30 between baseline and 8 hours (P < 0.0001) and between 8 and 16 hours (P = 0.035) but no significant change thereafter. LY30 at 8 hours (4%, range: 0%-23.4%) was not statistically different from control dogs (6.5%, range: 1.2%-32.8%, P = 0.664) suggesting early resolution of HF in this population. Only 2 of 18 dogs were persistently hyperfibrinolytic at 24 hours. Malignancy was diagnosed in 12 of 18 dogs (66.6%), while a benign etiology occurred in 6 of 18 dogs (33.3%). All HF dogs survived to discharge. CONCLUSIONS: HF occurs in some dogs with hypovolemic shock due to hemoperitoneum but resolves rapidly following surgical control of bleeding without antifibrinolytic medications. Routine postoperative use of antifibrinolytics in dogs with hemoperitoneum in dogs undergoing surgical control of bleeding may not be warranted.

Spontaneous Hemoperitoneum in Pregnancy and Endometriosis: A New Challenge in a Known Disease.

Importance: Spontaneous hemoperitoneum in pregnancy (SHiP) is a rare life-threatening event previously associated with endometriosis. Although pregnancy is thought to improve the symptoms of endometriosis, abrupt intraperitoneal bleeding can occur, jeopardizing both maternal and fetal outcomes. Objective: The aim of this study was to review the published information regarding SHiP pathophysiology, presentation, diagnosis, and management in a flowchart approach. Evidence Acquisition: A descriptive review of published articles in the English-language was carried out. Results: SHiP most commonly presents in the second half of pregnancy with a combination of abdominal pain, hypovolemia, a decline in hemoglobin level, and fetal distress. Nonspecific gastrointestinal symptoms are not uncommon. Surgical management is suitable in most scenarios and avoids complications such as recurrent bleeding and infected hematoma. Maternal outcome has improved greatly, whereas perinatal mortality remained unchanged. In addition to physical strain, SHiP was reported to have a psychosocial sequela. Conclusions and Relevance: A high index of suspicion is required when patients present with acute abdominal pain and signs of hypovolemia. Early use of sonography contributes to narrowing down the diagnosis. Health care providers should be familiar with the SHiP diagnosis because early identification is crucial when attempting to safeguard maternal and fetal outcomes. Maternal and fetal requirements are often contradictory, creating a greater challenge in decision-making and treatment. A multidisciplinary team approach should coordinate the treatment, whenever a SHiP diagnosis is suspected.

A uterine malformation diagnosed in the shock room: a case report which helps to identify how to avoid a potentially preventable life-threatening event.

An Indian wonen at her second pregnancy, with a previous preterm labour at 34.5 weeks, presented to the emergency room at 15.6 weeks, shocked due to massive hemoperitoneum. During the urgent surgery, a Mullerian malformation was detected, and a uterine rupture was diagnosed as the cause of the hemoperitoneum. Ultrasound and pelvic magnetic resonance results confirmed the malformation, determining that a unicornuate uterus with a rudimental horn within the pregnancy had taken place. We decided to report our case to underline that Mullerian malformation must be taken into consideration and evaluated at each routinary gynaecological visit or, at least, at the first pregnancy appointment, especially in the cases of women with previous adverse obstetric outcomes. The 2D abdominal ultrasound associated with trans-vaginal evaluation is an adequate procedure to test for suspected uterine malformations (if the operator keeps it in mind and is trained to check this kind of alteration), which is fundamental to reducing the risk of life-threatening events.

Spontaneous large liver haematoma with extensive intraperitoneal bleeding in a patient with COVID-19 infection.

Thrombotic complications during COVID-19 infections occur frequently, and anticoagulants to prevent and treat deep vein thrombosis appear to have a good safety profile in these patients. In addition, haemorrhagic complications during COVID-19 infections have also been reported. Hepatic inflammation can occur in COVID-19 infections as a direct consequence of cellular infection and cytopathy. Spontaneous subcapsular hepatic haematoma is extremely rare and can be life-threatening.A woman in her 40s presented to the hospital with fever and shortness of breath and was diagnosed with COVID-19 infection with respiratory failure requiring intubation. On day 49 of hospitalisation, she developed melena and acute anaemia; her haemoglobin dropped from 97g/L (9.7g/dL) to 56g/L (5.6g/dL). Abdominal and pelvic CT scans showed a large subcapsular liver haematoma with retroperitoneal extension. The patient received blood transfusions and remained haemodynamically stable. She was eventually extubated and discharged home.

Post-Cholecystectomy Right Hepatic Artery Pseudoaneurysm Induced by Generalized Seizure: A Case Report.

Pseudoaneurysm is a rare complication of laparoscopic cholecystectomy (LC). In most cases, the patient presents with gastrointestinal bleeding or hemoperitoneum. Here, we present a case with a post-cholecystectomy right hepatic artery pseudoaneurysm (PSA) induced by a generalized seizure. A 39-year-old male was sent to the emergency room with a generalized seizure and a loss of consciousness for approximately 5 min. Diffuse abdominal pain was complained of after consciousness returned. The surgical history of LC 13 days prior was mentioned. Abdominal computer tomography (CT) revealed a lobulated fluid accumulation in the gallbladder fossa with prominent fatty stranding and suspected biloma formation. After admission for one week, sharp abdominal pain was observed. Abdominal CT angiography revealed a right hepatic artery pseudoaneurysm. Transcatheter arterial embolization was performed with a total of seven platinum coils. In conclusion, it is important for doctors to take pseudoaneurysm into consideration in the patient who presents with seizure attack after receiving LC. Late discovery of PSA when it is ruptured can lead to fatal conditions, such as severe hemoperitoneum.

Perforated hemorrhagic cholecystitis in a patient with Bernard-Soulier syndrome.

Bernard-Soulier syndrome is an inherited coagulopathy, with an incidence of one per million. Hemorrhagic cholecystitis is a rare and life-threatening complication of acute cholecystitis. Less than 50 patients have been reported in the previous literature. Bleeding diathesis and anticoagulant treatment are well-known predisposing factors for hemorrhagic cholecystitis. We present a 57-year-old male patient who was referred to our department with a complaint of right upper quadrant abdominal pain. Contrast-enhanced computed tomography revealed a high-density mass associated with the gallbladder lumen, and blood clot in the gallbladder lumen and hemoperitoneum which were compatible for hemorrhagic cholecystitis and gallbladder perforation. The patient underwent urgent cholecystectomy. Hemorrhagic cholecystitis often manifests as typical acute cholecystitis presentation; but several clinical findings such as fever, lower gastrointestinal bleeding or severe intraabdominal bleeding-related hypovolemic shock may also occur. Most of the described cases in prior literature have been reported to use anticoagulant medications. This report describes the second hemorrhagic cholecystitis patient with inherited bleeding diathesis and the first case with Bernard-Soulier syndrome.

Arterial malformations leading to bilateral spontaneous renal hemorrhage in a dog.

OBJECTIVE: To describe the clinical presentation, diagnostic imaging, management, and follow-up of a dog that presented with sequential, bilateral, spontaneous, subcapsular and perirenal hemorrhage (Wunderlich syndrome) due to bilateral renal arterial malformations. CASE SUMMARY: A 9-year-old intact male Field Spaniel presented for acute onset abdominal pain following a possible syncopal episode. Abdominal ultrasonography, contrast-enhanced ultrasound, and computed tomography (CT) revealed right-sided perirenal hemorrhage that extended into the peritoneum. The dog was discharged following stabilization with analgesia, fluid therapy, and tranexamic acid. One month later, the patient presented with identical clinical signs. A CT scan at this stage revealed bilateral kidney infarcts with new left-sided perirenal hemorrhage. Abdominal ultrasound and contrast-enhanced ultrasound were repeated and showed similar findings. Follow up with four-dimensional CT angiography revealed bilateral renal arterial malformations, likely causing spontaneous renal hemorrhage and secondary subcapsular hematomas , retroperitoneal and peritoneal hemorrhage. UNIQUE INFORMATION PROVIDED: This is the first reported case of both bilateral renal arterial malformations and bilateral spontaneous subcapsular and perirenal hemorrhage in the absence of neoplasia, coagulopathy, or trauma in a dog. Advanced imaging modalities, including selective angiography, were required to diagnose this condition successfully. Arterial malformations should be considered as a differential diagnosis in cases of hemoretroperitoneum. Nephrectomy due to perirenal hemorrhage should be cautiously considered, especially in the absence of angiography, because of the sequential bilateral nature of this case. Conservative management in this case resulted in a good long-term outcome 10 months later.

Laparoscopic hemostasis for abdominal brunt massive hemorrhage due to endometriosis.

In the gynecological literature, a limited number of studies have reported intraperitoneal bleeding due to abdominal blunt trauma. In this report, we describe a rare case of massive intraabdominal hemorrhage from the uterine artery triggered by a fall injury without apparent abdominal bruising in the presence of severe endometriosis and a uterine fibroid. A 28-year-old woman who fell from a railway platform was transported to an emergency hospital. Although she did not sustain abdominal bruising and initially had no abdominal symptoms, she complained of gradually worsening abdominal pain. Abdominal CT identified intraabdominal massive hematoma, and emergency exploratory laparoscopy revealed active bleeding from the right uterine artery eroded by endometriosis, which was treated with laparoscopic electrocoagulation. The cause of the intraabdominal bleeding was associated with avulsion of the endometriosis adhesion between the right perimetrium and the right uterine artery due to inertial forces of the uterus during the fall injury. A uterine fibroid discovered during laparoscopy was suspected to strengthen the inertial forces of the uterus. In the case of hemoperitoneum after trauma, gynecological sources of bleeding must be kept in mind, especially for patients with a known history of fibroids or endometriosis.

A positive urine pregnancy test with haemoperitoneum: misdiagnosed postpartum choriocarcinoma with uterine rupture mimicking ruptured ectopic pregnancy.

OBJECTIVES: Choriocarcinoma after a term pregnancy is rare and can be life-threatening, especially when it perforates the uterus, resulting in massive haemoperitoneum. As uterine rupture due to choriocarcinoma is uncommonly encountered in the clinical practice, its diagnosis is often missed or delayed. CASE PRESENTATION: We present a case of a 41-year-old para 4 + 1 who had acute abdomen and hypovolaemic shock secondary to haemoperitoneum at three months postpartum period. The urine pregnancy test was positive, and, therefore, a provisional diagnosis of a ruptured ectopic pregnancy was made. She was managed aggressively with fluids and blood product transfusion at the emergency department to achieve haemodynamic stability. Subsequently, she underwent an emergency laparotomy where intraoperatively noted a perforation at the left posterior uterine cornu with purplish tissue spillage. A wedge resection was performed, and the histopathological examination (HPE) was reported as atypical trophoblastic cells, in which choriocarcinoma could not be ruled out. The patient then underwent a total abdominal hysterectomy three weeks later. The final HPE confirmed the diagnosis of choriocarcinoma. CONCLUSIONS: The clinical presentation of postpartum choriocarcinoma can be indistinguishable from a ruptured ectopic pregnancy. A high index of suspicion is crucial to allow early diagnosis.

Glass table tops: An unusual source of lethal domestic injury.

A 42-year-old woman who fell through a glass tabletop had her lower back pierced by a long shard of glass. She rapidly exsanguinated. At autopsy, a single penetrating wound was present in her left lower back, with complete transection of her left kidney and a 3.5 L haematoperitoneum. Death was due to exsanguination following accidental transection of the left kidney by a penetrating glass injury of the lower back. Glass-topped tables are a well-recognised source of injury in a domestic setting There are far more non-lethal than lethal injuries, many of which involve children. Quite long shards may remain undetected in wounds for considerable amounts of time. Non-tempered glass is a particular risk for breakage. Glass-topped tables should not be used as substitutes for chairs, particularly in overweight or obese individuals.

Anaphylaxis-related hemoperitoneum in 11 dogs.

OBJECTIVE: To describe the unique complication of hemoperitoneum associated with anaphylaxis. DESIGN: Retrospective case series from September 2012 to August 2017. SETTING: Two private emergency and specialty referral hospitals. ANIMALS: Eleven client-owned dogs diagnosed with anaphylaxis and hemoperitoneum upon presentation or referral. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Inclusion criteria included clinical signs consistent with anaphylaxis (hypotension, tachycardia, vomiting, diarrhea, weakness, collapse, with or without the presence of dermal signs) due to witnessed or unwitnessed presumed bee sting, an elevated alanine aminotransferase (ALT), performance of abdominal FAST (AFAST) examination with an abdominal fluid score, the sonographic presence of gallbladder wall edema, and hemoperitoneum. All dogs (n=11) were managed medically without surgical intervention. 91% (n=10) of dogs survived to discharge. CONCLUSIONS: Hemoperitoneum development can be seen with anaphylactic reactions, though the exact mechanism remains to be fully understood. Medical therapy is warranted and can be successful in these patients; surgery is not indicated to address hemoperitoneum.
