Spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma: a rare case.

BACKGROUND: Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. CASE PRESENTATION: A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity. Immediately afterwards, he was admitted to our department, and then we arranged a computed tomography with intravenously administered contrast agent showed a spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. Therefore, we treated him with anticoagulation and conservative observation. During his stay in the hospital, he was given low-molecular heparin by subcutaneous injection for anticoagulation therapy, and after discharge, he was given oral anticoagulation therapy with rivaroxaban. At the follow-up of more than 4 months, most of the intramural hematoma was absorbed and became significantly smaller, and the intermural hematoma of the superior mesenteric artery was basically absorbed, which also confirmed that the intramural mass was an intramural hematoma. CONCLUSION: A gastric intramural hematoma should be considered, when an intra-abdominal mass was found to be attached to the gastric wall. Proper recognition of gastric intramural hematoma can reduce the misdiagnosis rate of confusion with gastric cancer.

Successful Transcatheter Arterial Embolization of Abdominal Wall Hematoma from the Left Deep Circumflex Iliac Artery after Abdominal Paracentesis in a Patient with Liver Cirrhosis: Case Report and Literature Review.

The occurrence of an abdominal wall hematoma caused by abdominal paracentesis in patients with liver cirrhosis is rare. This paper presents a case of an abdominal wall hematoma caused by abdominal paracentesis in a 67-year-old woman with liver cirrhosis with a review of the relevant literature. Two days prior, the patient underwent abdominal paracentesis for symptom relief for refractory ascites at a local clinic. Upon admission, a physical examination revealed purpuric patches with swelling and mild tenderness in the left lower quadrant of the abdominal wall. Abdominal computed tomography revealed advanced liver cirrhosis with splenomegaly, tortuous dilatation of the para-umbilical vein, a large volume of ascites, and a large acute hematoma at the left lower quadrant of the abdominal wall. An external iliac artery angiogram showed the extravasation of contrast media from the left deep circumflex iliac artery. Embolization of the target arterial branches using N-butyl-2-cyanoacrylate was then performed, and the bleeding was stopped. The final diagnosis was an abdominal wall hematoma from the left deep circumflex iliac artery after abdominal paracentesis in a patient with liver cirrhosis.

MEDICO-LEGAL APPLICATIONS OF FRACTURE HEMATOMA: REVIEW.

This review aimed to elucidate the critical role of fracture hematoma in forensic medicine, with a specific focus on its utility in differentiating antemortem from postmortem fractures. The study seeks to provide a comprehensive synthesis of current knowledge on the subject, highlighting the biological and medico-legal implications of fracture hematoma analysis in forensic investigations. A systematic review of literature was conducted, encompassing various scientific databases including PubMed, Scopus, and Web of Science, focusing on studies published from 2000 to 2024. The search employed keywords such as "fracture hematoma," "antemortem fractures," "perimortem fractures" and "postmortem fractures," among others, to explore relevant data. Selected studies were scrutinized based on their relevance, the presence of substantial data on fracture hematoma, and their contribution to forensic analysis. The review underscores the significance of fracture hematoma as an indicator of antemortem injuries, revealing that active blood circulation at the time of injury facilitates hematoma formation. Detailed analyses within the selected studies illustrate the interplay of cellular and molecular dynamics within fracture hematomas, emphasizing the roles of cytokines, particularly IL-6, and cellular constituents in the healing process. Fracture hematoma analysis emerges as a vital forensic tool in establishing the vitality of bone fractures, enhancing the accuracy of forensic assessments. However, the review also acknowledges the challenges posed by individual healing variability and postmortem changes, suggesting a need for further research to refine the interpretative frameworks used in forensic hematoma analysis.

Nontraumatic orbital hematoma secondary to labor and childbirth: a case report and review of the literature.

PURPOSE: Non-traumatic orbital hemorrhage without underlying vascular malformations or predisposing conditions is uncommon, and particularly rare in the context of maternal labor. This study combines a novel case report and retrospective review to analyze reported cases and propose insights. METHODS: This study is both a unique case report and literature review examining PubMed publications with articles traced back to original sources through citations for inclusion. Analysis included clinical presentation, visual examination, hematoma characteristics, neuroimaging, management strategies, and outcomes. RESULTS: We present a 37-year-old multigravida woman at 40 weeks gestation who developed acute right-sided proptosis, diplopia, retrobulbar pain, and periorbital edema during the second stage of labor. Computed tomography (CT) revealed a subperiosteal hemorrhage, with subsequent magnetic resonance imaging (MRI) excluding vascular anomalies. Symptoms resolved within two months. Only 14 cases of maternal orbital hematoma associated with labor have been reported. The average age was 28 with 42% (6/14) being primigravid. Including our case, forty percent (6/15) developed symptoms during the second stage of labor, 40% (6/15) immediately postpartum, and 20% (3/15) over 24 hours postpartum. Overall, 33% (5/15) had potentially contributing conditions including coagulopathies, delivery complications, or vascular malformations. Unilateral orbital hemorrhage occurred in 87% (13/15). Surgical intervention was necessary in 13% (2/15). Most (87%, 13/15) underwent observation or medical management with full recovery of symptoms. CONCLUSIONS: Non-traumatic orbital hematomas associated with maternal labor are rare and likely related to increased valsalva during delivery and heightened blood volume in pregnancy. Neuro-imaging and systemic workup are recommended to assess for vascular anomalies or underlying coagulopathies. The overall prognosis is favorable with most having full recovery.

Optimal intraventricular hemorrhage volume cutoff for predicting poor outcome in patients with intracerebral hemorrhage.

BACKGROUND AND OBJECTIVES: The prognosis of patients with spontaneous intracerebral hemorrhage (ICH) is often influenced by hematoma volume, a well-established predictor of poor outcome. However, the optimal intraventricular hemorrhage (IVH) volume cutoff for predicting poor outcome remains unknown. METHODS: We analyzed 313 patients with spontaneous ICH not undergoing evacuation, including 7 cases with external ventricular drainage (EVD). These patients underwent a baseline CT scan, followed by a 24-hour CT scan for measurement of both hematoma and IVH volume. We defined hematoma growth as hematoma growth > 33 % or 6 mL at follow-up CT, and poor outcome as modified Rankin Scale score≥3 at three months. Cutoffs with optimal sensitivity and specificity for predicting poor outcome were identified using receiver operating curves. RESULTS: The receiver operating characteristic analysis identified 6 mL as the optimal cutoff for predicting poor outcome. IVH volume> 6 mL was observed in 53 (16.9 %) of 313 patients. Patients with IVH volume>6 mL were more likely to be older and had higher NIHSS score and lower GCS score than those without. IVH volume>6 mL (adjusted OR 2.43, 95 % CI 1.13-5.30; P = 0.026) was found to be an independent predictor of poor clinical outcome at three months in multivariable regression analysis. CONCLUSIONS: Optimal IVH volume cutoff represents a powerful tool for improving the prediction of poor outcome in patients with ICH, particularly in the absence of clot evacuation or common use of EVD. Small amounts of intraventricular blood are not independently associated with poor outcome in patients with intracerebral hemorrhage. The utilization of optimal IVH volume cutoffs may improve the clinical trial design by targeting ICH patients that will obtain maximal benefit from therapies.

[Spontaneous retroperitoneal hematoma]. / Spontaan retroperitoneaal hematoom.

Spontaneous retroperitoneal hematoma refers to bleeding of the retroperitoneal space without prior trauma or iatrogenic injury. Its diagnosis is often delayed due to a nonspecific clinical presentation. This case-series presents three patients with spontaneous retroperitoneal bleeding. Patient A presented with a spontaneous bleeding around the right iliopsoas muscle due to antiplatelet medication and was managed conservatively. Patient B had a spontaneous arterial bleeding near the right kidney, subsequently determined to be associated with a pheochromocytoma. Endovascular treatment successfully stopped the bleeding. The pheochromocytoma was resected during follow-up. Patient C had a spontaneous rupture of the left iliac vein with a concomitant deep vein thrombosis. She underwent emergent laparotomy, but unfortunately did not survive. This case-series emphasize the diverse presentation, varied causes, and different treatment strategies for spontaneous retroperitoneal hematoma. Timely diagnosis is hard, but crucial to enable an individualized treatment.

[A man with fluctuating swelling while coughing]. / Een man die de longen uit z'n lijf hoest.

A 66-year-old man presented to the general practitioner several times with persistent coughing, haematoma formation and swelling fluctuating in size during coughing. An CT scan showed a widened seventh intercostal space based on a rupture of the intercostal muscles with a herniation of part of the left lower lobe.

Unusual case of retroperitoneal hematoma and duodenal ulcerative bleeding after nephrectomy: Case report.

RATIONALE: Retroperitoneal hematomas are relatively common in patients undergoing nephrectomy. Herein, we report an unusual case involving a giant retroperitoneal hematoma and subsequent duodenal ulcerative bleeding following a radical nephrectomy. PATIENT CONCERNS: A 77-year-old woman was admitted to our hospital for lower back pain, and she had severe right hydronephrosis and a urinary tract infection. DIAGNOSES: The patient was diagnosed and confirmed as high-grade urothelial carcinoma. INTERVENTIONS: After ineffective conservative treatments, a right radical nephrectomy and ureteral stump resection were performed. The patient received proton pump inhibitors to prevent stress ulcer formation and bleeding. On the first day post-surgery, she had normal gastrointestinal (GI) endoscopy findings. On the second day post-surgery, abdominal computed tomography revealed a retroperitoneal hematoma. Notably, 14 days post-surgery, massive GI bleeding occurred, and GI endoscopy identified an almost perforated ulcer in the bulbar and descending duodenum. OUTCOMES: The patient died on day 15 after surgery. LESSONS: Duodenal ulceration and bleeding might occur following a retroperitoneal hematoma in patients treated with nephrectomy. Timely intervention may prevent duodenal ulcers and complications, and thus could be a promising life-saving intercession.

Extraplaque blood withdrawal stenting: A miraculous cure for subintimal hematoma.

We report the Extraplaque Blood Withdrawal stenting technique to treat chronic total occlusion percutaneous coronary intervention (CTO PCI)-induced extraplaque hematoma.

A Rare Case of Page Kidney in a Young Man with Flank Pain.

BACKGROUND: Page kidney is a rare condition in which an external compression of the kidney as a result of a hematoma or mass causes renal ischemia and hypertension. In a patient with flank pain, elevated blood pressure, and recent trauma, this condition should be considered. Since this condition was first described in 1939, more than 100 case reports have surfaced. CASE REPORT: We describe the case of a 26-year-old man who presented to the Emergency Department with flank pain, vomiting, and elevated blood pressure. A computed tomography scan of the abdomen and pelvis confirmed the presence of a perinephric hematoma, and the interventional radiology team was consulted to resolve the Page kidney. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptoms seen in Page kidney may be similar to other more common diagnoses encountered in the emergency department. It is important to maintain a high suspicion and order imaging studies as needed, especially in the setting of trauma, or a recent procedure in the vicinity of the renal parenchyma.

[Comparison of planimetric CT­based volumetry with simplified models for determining the size of intrapelvic hematomas due to pelvic fractures in emergency room diagnostics]. / Vergleich von planimetrisch CT­gestützter Volumetrie mit vereinfachten Modellen zur Größenbestimmung intrapelviner Hämatome bei Beckenfrakturen im Rahmen der Schockraumdiagnostik.

BACKGROUND: Bleeding in the pelvis can lead to a circulatory problem. The widely used whole-body computed tomography (WBCT) scan in the context of treatment in the trauma resuscitation unit (TRU) can give an idea of the source of bleeding (arterial vs. venous/osseous); however, the volume determination of an intrapelvic hematoma by volumetric planimetry cannot be used for a quick estimation of the blood loss. Simplified measurement techniques using geometric models should be used to estimate the extent of bleeding complications. OBJECTIVE: To determine whether simplified geometric models can be used to quickly and reliably determine intrapelvic hematoma volume in fractures type Tile B/C during emergency room diagnostics or whether the time-consuming planimetric method must always be used. MATERIAL AND METHODS: Retrospectively, 42 intrapelvic hemorrhages after pelvic fractures Tile B + C (n = 8:B, 34:C) at two trauma centers in Germany were selected (66% men, 33% women; mean age 42 ± 20 years) and the CT scans obtained during the initial trauma scan were analyzed in more detail. The CT datasets of the included patients with 1-5 mm slice thickness were available for analysis. By area labelling (ROIs) of the hemorrhage areas in the individual slice images, the volume was calculated by CT volumetrically. Comparatively, volumes were calculated using simplified geometric figures (cuboid, ellipsoid, Kothari). A correction factor was determined by calculating the deviation of the volumes of the geometric models from the planimetrically determined hematoma size. RESULTS AND DISCUSSION: The median planimetric bleeding volume in the total collective was 1710 ml (10-7152 ml). Relevant pelvic bleeding with a total volume > 100 ml existed in 25 patients. In 42.86% the volume was overestimated in the cuboid model and in 13 cases (30.95%) there was a significant underestimation to the planimetrically measured volume. Thus, we excluded this volume model. In the models ellipsoid and measuring method according to Kothari, an approximation to the planimetrically determined volume could be achieved with a correction factor calculated via a multiple linear regression analysis. The time-saving and approximate quantification of the hematoma volume using a modified ellipsoidal calculation according to Kothari makes it possible to assess the extent of bleeding in the pelvis after trauma if there are signs of a C-problem. This measurement method, as a simple reproducible metric, could be embedded in trauma resuscitation units (TRU) in the future.

Sinonasal Organizing Hematoma: Demographics, Diagnosis, and Treatment Outcomes of 112 patients.

INTRODUCTION: Sinonasal organizing hematoma (OH) is a rare, nonneoplastic lesion that often presents with epistaxis, a reddish mass, and destruction of the involved sinonasal structures. Due to its rarity, the demographics, diagnostic modalities, treatment strategies, and outcomes have not yet been studied in a large, long-term study. MATERIALS AND METHODS: Retrospect cohort of 112 sinonasal OH patients treated between 1997 and 2020 in a tertiary, university hospital were evaluated. Demographics, systemic comorbidities, sinonasal surgery history, serum laboratory tests, radiological findings, and treatment results were collected. The present study aimed to assess the accuracy of preoperative computed tomography (CT), Gadolinum-enhanced magnetic resonance (MR), and punch biopsies in detecting sinonasal OH as the most likely diagnosis. In addition, incidental differences by age and year of diagnosis were calculated using the Poisson log-linear regression model. RESULTS: The median age was 44, and 58% were male. Fewer than 20% of these cases had a chronic systemic comorbidity, bleeding tendency, or sinonasal surgery history. MR had the highest accuracy of (87%) to detect sinonasal OH as the most likely diagnosis, compared with contrast-enhanced-CT (53%), punch biopsy (49%), and non-enhanced-CT (16%) (all <0.05). Sinonasal OH incidence did not vary by age, but the yearly rate significantly increased by 1.05 times over 23 years (p < 0.05). Notably, 84% of 112 patients received surgical removal through the assistance of an endoscope, and none had substantial bleeding without preoperative embolization. CONCLUSION: Sinonasal OH was observed regardless of age, sex, systemic comorbidities, bleeding tendency, prior sinonasal surgery, or trauma. Preoperative MR gives the highest accuracy for detecting this disease. Sinonasal OH may be safely managed with endoscopic-assisted surgery removal without embolization.

Diagnostic potential of soluble ST2 and D-dimer for Stanford Type B aortic dissection and intramural aortic hematoma.

OBJECTIVE: Type B aortic dissection (TBAD) and intramural aortic hematoma (IMH) are common manifestations of Acute Aortic Syndrome (AAS), exhibiting overlapping clinical features. The timely and accurate diagnosis and differentiation between TBAD and IMH are critical for appropriate management. Tumorigenicity 2 (sST2) and D-dimer have been shown to elevate levels in both TBAD and IMH, making them valuable as "rule-out" markers. Hence, we aimed to assess the diagnostic utility of sST2 and D-dimer in distinguishing TBAD from IMH. METHODS: In this retrospective study, we analyzed serum levels of sST2 and D-dimer in 182 AAS patients, comprising 90 TBAD cases, 92 IMH cases, and 90 non-AAS cases. Serial measurements were taken at 1 h, 6 h, 12 h, 24 h, and 72 h post-admission. Comparative analyses were conducted between TBAD and non-AAS cases, IMH and non-AAS cases, and TBAD and IMH cases. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic accuracy of sST2 and D-dimer in identifying TBAD or IMH cases. RESULTS: Both TBAD and IMH patients displayed elevated levels of sST2 and D-dimer compared to non-AAS cases. Notably, sST2 levels were significantly higher in TBAD patients than in IMH patients, whereas D-dimer levels exhibited moderate differences. TBAD patients tended to exhibit elevated levels of either sST2 or D-dimer, with a modest correlation between the two (Pearson correlation coefficient = 0.3614). In contrast, IMH patients showed elevations in both markers, with a positive correlation between them (Pearson correlation coefficient = 0.6814). The ROC analysis revealed that both sST2 (AUC, 0.657; 95 % CI, 0.552-0.753; cutoff value, 27.54 ng/ml) and D-dimer (AUC, 0.695; 95 % CI, 0.591-0.787, cutoff value, 1.215 ng/ml) demonstrated favorable diagnostic performance for TBAD. sST2 exhibited a sensitivity of 80.92 % and a specificity of 75.00 %, while D-dimer showed a sensitivity of 80.92 % and a specificity of 75.00 %. For the diagnosis of IMH, the combined assessment of sST2 and D-dimer (AUC, 0.674; 95 % CI, 0.599-0.768; sensitivity, 69.20 %; specificity, 80.00 %) proved effective. CONCLUSIONS: Our results indicate that both sST2 and D-dimer show diagnostic potential for TBAD. Elevated levels of either serve as an indicator of TBAD onset. However, concurrent elevation of both markers seems to be indicative of IMH. The combination of increased sST2 and D-dimer levels demonstrates strong diagnostic performance in identifying IMH cases.

Large supralevator haematoma: a dilemma in diagnosis and management.

This is a case of postpartum haemorrhage following vaginal delivery of a primigravida in her late 20s resulting from a supralevator haematoma. She delivered in a low-resource hospital setting, with a late diagnosis of severe pre-eclampsia and haemolysis, elevated liver enzymes and low platelet count (HELLP), subsequently developed traumatic postpartum haemorrhage and vaginal haematoma, and was referred to our hospital for further management. She was constantly monitored, and serial ultrasonography revealed an expanding paravaginal haematoma. CT, 4 hours after admission, showed a large ill-defined collection with hyperdense areas of blood attenuation measuring ~8.0×6.2×12.2 cm in toto in the vaginal canal and right paravaginal region with supralevator extension, abutting the rectum posteriorly. The expanding haematoma caused gradual hypovolaemic shock, and hence, she was taken up for vaginal evacuation of supralevator haematoma with drainage tube insertion under ultrasound guidance. She received multiple blood product transfusion. Drain tube was removed on postoperative day 3. Follow-up scan was done and resolving haematoma noted. The patient was discharged on postoperative day 5 in a stable condition. She was followed up in outpatient department, and there was complete resolution of haematoma by 4 weeks.

The impact of time to evacuation on outcomes in endoscopic surgery for supratentorial spontaneous intracerebral hemorrhage: a single-center retrospective study.

Supratentorial spontaneous intracerebral hemorrhage (SICH) can be treated with endoscopic surgery, but the optimal timing remains uncertain. We retrospectively analyzed data from 46 patients who underwent endoscopic surgery for supratentorial SICH. We examined the relationship between time to evacuation and functional outcome at 3 months, adjusting for prognostic factors. Surgical outcomes and complications were compared between patients with early (≤ 12 h) or late (> 12 h) evacuation. Median time to evacuation was 12 h, and the rate of unfavorable outcome (modified Rankin Scale > 3 at 3 months) was 32.6%. Longer time to evacuation was independently associated with unfavorable outcome (odds ratio per hour delay: 1.26). Late evacuation carried a 7.25-fold higher risk of unfavorable outcome compared to early evacuation. This association held across subgroups based on hematoma volume, location, and intraventricular extension (P for interaction > 0.05). Patients with late evacuation had fewer spot signs (24% vs. 4.8%, P = 0.035) and markers of hemorrhagic expansion (36% vs. 9.5%, P = 0.018), longer neurosurgical intensive care unit (NSICU) stay (3.2 vs. 1.9 days, P = 0.011) and hospital stay (15.7 vs. 11.9 days, P = 0.014), and higher 30-day mortality (28.6 vs. 4%, P = 0.036) and complication rates (57.1% vs. 28.0%, P = 0.023). This study suggests a potential association between early endoscopic evacuation of supratentorial SICH and improved functional outcomes, lower 30-day mortality and reduced complications. The need for timely intervention in managing supratentorial SICH is highlighted, yet further validation through multi-center prospective studies is essential to substantiate these findings and provide a higher level of evidence.

How to predict the outcome of primary brainstem hemorrhage: Six-year results of a single-center retrospective analysis.

Primary brainstem hemorrhage (PBH) is one of the most fatal intracranial hemorrhages, evaluating the prognosis in the early stage is vital for appropriate therapeutic planning. Our study aimed to identify risk factors for 30-day mortality and 90-day functional recovery of PBH. Data from 63 patients with PBH admitted to Beijing Chaoyang Hospital between 2016 and 2022 were retrieved for this study. We grouped the patients according to 30-day survival or 90-day functional recovery. Independent risk factors of 30-day mortality and 90-day functional recovery were identified by univariate and multivariate logistic regression analyses. 31 patients (49.2%) died within 30 days and 22 patients (34.9%) achieved better functional recovery. By multivariate analysis, Glasgow coma scale <9 on admission and tachycardia were significantly associated with 30-day mortality, while the hematoma volume >5 mL was an independent risk factor for 90-day functional recovery. Initial level of consciousness, tachycardia, massive hematoma were risk factors for prognosis, which must be seriously evaluated for therapeutic planning.
