Red dichromatic imaging reduces bleeding and hematoma during submucosal injection in esophageal endoscopic submucosal dissection

BACKGROUND

Bleeding and hematoma formation during submucosal injection in esophageal endoscopic submucosal dissection (ESD) reduce the visibility of the submucosa. Red dichromatic imaging (RDI) is an endoscopic technique that provides better visualization of the deep submucosal blood vessels. We speculated that blood vessel injury could be avoided with RDI. This pilot study evaluated the role of RDI in preventing bleeding and hematoma formation during esophageal ESD.

METHODS

This was a single-center retrospective observational study. We examined 60 patients who underwent ESD with white light imaging (WLI) and RDI. A single endoscopist reviewed all of the surgical videos to document the incidence and severity of bleeding episodes. Eighteen videos provided adequate quality and detail, and the number of blood vessels traversing the mucosal incision lines of the lesions in these videos was evaluated under WLI and RDI.

RESULTS

The WLI group had a significantly higher incidence of hematomas per unit area compared to the RDI group (0.18/cm² [range 0-0.38] vs. 0 [0-0.18]/cm², p = 0.024). The WLI group also had a significantly higher incidence of total bleeding episodes compared to the RDI group (42.9% [range 21.7-60.4] vs 16.7% [range 13.8-22.9], p < 0.001). Significantly more blood vessels were visible under RDI compared to WLI (5 [range 4-8] vs. 2 [range 1-5], p = 0.0020).

CONCLUSION

RDI reduced the incidence of bleeding and hematoma formation during submucosal injection in esophageal ESD. It was assumed that the improvement of blood vessel visibility by RDI might have contributed to the result.

Early posttraumatic CSF1R inhibition via PLX3397 leads to time- and sex-dependent effects on inflammation and neuronal maintenance after traumatic brain injury in mice

BACKGROUND

There is a need for early therapeutic interventions after traumatic brain injury (TBI) to prevent neurodegeneration. Microglia/macrophage (M/M) depletion and repopulation after treatment with colony stimulating factor 1 receptor (CSF1R) inhibitors reduces neurodegeneration. The present study investigates short- and long-term consequences after CSF1R inhibition during the early phase after TBI.

METHODS

Sex-matched mice were subjected to TBI and CSF1R inhibition by PLX3397 for 5 days and sacrificed at 5 or 30 days post injury (dpi). Neurological deficits were monitored and brain tissues were examined for histo- and molecular pathological markers. RNAseq was performed with 30 dpi TBI samples.

RESULTS

At 5 dpi, CSF1R inhibition attenuated the TBI-induced perilesional M/M increase and associated gene expressions by up to 50%. M/M attenuation did not affect structural brain damage at this time-point, impaired hematoma clearance, and had no effect on IL-1β expression. At 30 dpi, following drug discontinuation at 5 dpi and M/M repopulation, CSF1R inhibition attenuated brain tissue loss regardless of sex, as well as hippocampal atrophy and thalamic neuronal loss in male mice. Selected gene markers of brain inflammation and apoptosis were reduced in males but increased in females after early CSF1R inhibition as compared to corresponding TBI vehicle groups. Neurological outcome in behaving mice was almost not affected. RNAseq and gene set enrichment analysis (GSEA) of injured brains at 30 dpi revealed more genes associated with dendritic spines and synapse function after early CSF1R inhibition as compared to vehicle, suggesting improved neuronal maintenance and recovery. In TBI vehicle mice, GSEA showed high oxidative phosphorylation, oxidoreductase activity and ribosomal biogenesis suggesting oxidative stress and increased abundance of metabolically highly active cells. More genes associated with immune processes and phagocytosis in PLX3397 treated females vs males, suggesting sex-specific differences in response to early CSF1R inhibition after TBI.

CONCLUSIONS

M/M attenuation after CSF1R inhibition via PLX3397 during the early phase of TBI reduces long-term brain tissue loss, improves neuronal maintenance and fosters synapse recovery. Overall effects were not sex-specific but there is evidence that male mice benefit more than female mice.

Spontaneous acute forearm compartment syndrome: Case report of a clinical diagnosis with limited imaging options

Diagnostic radiology is essential for providing targeted management of different diseases. Thus, there has been a dramatic increase in the demand for medical imaging. However, acute compartment syndrome (ACS) is one of the clinical scenarios in which radiology has limited value. The authors report a nontraumatic spontaneous ACS in the forearm of a 56-year-old female. The roles of Ultrasound and MRI, if available, are also illustrated. Limited reports of spontaneous ACS are published in the literature; we hope this case adds to the limited data. Our goal in reporting this case is to improve clinical practice with favorable outcomes for the patients involved globally by alert to the onset of ACS to promote early detection and timely fasciotomy. Also, we aim to increase awareness among physicians and radiologists of the limitations of radiology in specific clinical scenarios. Finally, it may aid in illuminating a possible link between malignant hypertension, spontaneous bleeding/hematoma, and ACS.

Surgical demographics of acute thigh compartment syndrome

BACKGROUND

The objective of this study was to identify demographic, injury-related, and treatment-related characteristics of patients who underwent decompressive fasciotomies for acute thigh compartment syndrome.

METHODS

A cohort of 38 adult patients with acute thigh compartment syndrome treated with fasciotomy at two tertiary care referral centers over a 10-year time period from January 1, 2006 to June 30, 2015 were retrospectively identified. We searched the electronic medical record for patient-related variables (e.g., age, sex, race, smoking status, diabetes mellitus), injury-related variables (e.g., mechanism of injury, associated fractures, other traumatic injuries), treatment-related variables (e.g., delay to treatment, compartments released, number of debridements, use of split-thickness grafts), and outcomes (e.g., amputation, death, sensory/motor impairments at final follow-up).

RESULTS

The mean age of our cohort was 47 years, and 35 patients (92%) were male. There were various mechanisms of injury, but the most common mechanisms were spontaneous hematoma (21%), followed by motor vehicle accidents (16%). Associated leg fractures were present in 15 (39%) patients. Delay between time of injury and fasciotomy was greater than 24 hours in 27 patients (71%), 12 to 24 hours in 6 patients (16%), and less than 6 hours in 3 patients (8%). The most frequently released compartment was the anterior compartment only (68%), followed by both the anterior and posterior compartments (16%) and the posterior compartment only (11%). Six patients (16%) had motor impairment, and 2 patients (5%) had sensory impairment at final follow-up. There were 2 deaths (5%) recorded in the hospital course for this cohort, none of which were directly related to compartment syndrome of the thigh.

CONCLUSION

Delays to fasciotomy are frequent in the treatment of acute thigh compartment syndrome. The demographics of acute thigh compartment syndrome demonstrate a strong male predominance. Treating providers should recognize spontaneous hematoma and motor vehicle accidents as the most common causes of acute thigh compartment syndrome.

Retroperitoneal hematoma in patients with COVID-19 infection during anticoagulant therapy: A case series and literature review

Due to the hypercoagulable status of patients with severe COVID-19 infection, anticoagulants are often used to prevent thrombosis. However, these agents may cause bleeding events such as retroperitoneal hematoma (RPH). We report here on six patients with COVID-19 who developed RPH during treatment. Early evidence of bleeding led to confirmatory diagnosis with imaging. Four patients recovered with supportive treatment (IV fluids and blood transfusions) and two patients recovered by angioembolization. RPH should be considered in COVID patients on anticoagulants as soon as haemoglobin or blood pressure falls. Further studies are required to provide guidance and recommendations on use of anticoagulants in critically ill patients with COVID-19.

Tumor-like disorder of the brachial plexus region in a patient with hemophilia: A case report

BACKGROUND

Various tumors and tumor-like disorders, originating from the neural sheath, as well as other types, may affect the brachial plexus region. Due to the infrequent presentation, brachial plexus palsy caused by spontaneous hematoma in patients with hemophilia might miss the treatment by early surgical decompression and progress to permanent nerve damage.

CASE SUMMARY

The case reported here was a 30-year-old man with hemophilia, as well as both sensory and motor dysfunction of the left upper extremity. A presumptive diagnosis of brachial plexus tumor was initially made, which was subsequently confirmed to be an organized chronic hematoma rather than a neoplasm. The hemophilia-induced expanding hematoma compressing the brachial plexus was considered to be the main reason for the patient’s complaints. The clinical symptoms were alleviated and the involved nerves partially recovered at a follow-up of 1 year.

CONCLUSION

Early surgical intervention is crucial and it seems to be an essential precondition for recovery of nerve function in brachial plexus lesions.

A case of cribriform plate dural arteriovenous fistulas with a rare complication after endovascular therapy

Background:

Cribriform plate dural arteriovenous fistulas (dAVFs) are rarely encountered. Here, we report a case of cribriform plate dAVF with a rare complication after endovascular therapy.

Case Description:

A 60-year-old man presented with severe sudden headache. Head computed tomography showed right subdural hematoma, and magnetic resonance angiography showed dilated bilateral frontal cortical vein. Digital subtraction angiography revealed cribriform plate dAVF fed by the anterior and posterior ethmoidal branches of the bilateral ophthalmic arteries. Transarterial embolization with liquid embolic material was performed and the fistula disappeared. Although magnetic resonance imaging showed the disappearance of the cribriform plate dAVF and subdural hematoma, the patient complained of anosmia after the procedure.

Conclusion:

Endovascular embolization is an effective treatment option for treating cribriform plate dAVFs. However, anosmia is a possible complication, and endovascular surgeons should take care of this complication, especially in cribriform plate dAVFs supplied with blood bilaterally.

Edema and hematoma after local anesthesia via posterior superior alveolar nerve block: a case report

Although rare, complications can occur with anesthetic procedures. The posterior superior alveolar nerve (PSAN) block anesthetic technique has a high success rate, but positive aspiration can cause bruising, transient diplopia, blurred vision, and temporary blindness in approximately 3% cases. When edema occurs, it is occasionally massive, especially in the infratemporal fossa, and the resulting hematoma is usually unsightly. A 20-year-old woman presented with massive edema followed by hematoma in the upper right jaw immediately after PSAN block administration, which subsequently spread to the oral mucosa. The patient did not report any complications during the anesthetic procedure. However, after the injection was administered, the patient experienced anesthetic sensations, which rapidly evolved to facial edema. There was mild pain, but without intraoral or extraoral bleeding. The patient was prescribed medicines and instructed to perform contrast therapy. Although hematomas and edema are rare, they are difficult to prevent. The choice of local anesthetic and appropriate application of the anesthetic technique can minimize their occurrence.

Prognostic factors for spontaneous spinal epidural hematoma: a multicenter case-control study

BACKGROUND

To determine the optimal treatment for spontaneous spinal epidural hematoma (SSEH). The aim of this study was to identify factors associated with SSEH.

METHODS

In 62 patients with SSEH, several patient-related parameters were analyzed as candidate factors associated with Frankel grade before treatment or at the last follow-up. These parameters were compared between patients with and without surgery. In addition, multivariate ordinal logistic regression analysis was used to identify factors significantly associated with Frankel's grade before treatment or at the last follow-up.

RESULTS

There were significant differences in age, location of the hematoma, and Frankel grade before treatment and at the last follow-up between surgical and nonsurgical cases in all patients, but there were no significant differences in any of these parameters when comparing patients with pre-treatment Frankel grade C. The location of the hematoma was significantly associated with the severity of paralysis before treatment. In surgical cases, the time from onset to surgery and the location of the hematoma was significantly associated with the prognosis. When the time from onset to surgery was evaluated using the criteria of 12, 24, and 48 h, 24 and 48 h had a significant impact on the prognosis. In the analysis of nonsurgical cases, only the vertical size of the hematoma was significantly associated with prognosis.

CONCLUSION

The time from onset to surgery and the location of the hematoma were prognostic factors in surgical cases, while the vertical size of the hematoma was a prognostic factor in nonsurgical cases.

Hematoma following gender-affirming mastectomy: A systematic review of the evidence

BACKGROUND

Hematomas are reported to be the most common immediate complication in patients undergoing gender-affirming mastectomy, with rates substantially higher than those associated with other types of breast surgery. This study sought to examine the breadth of current literature and provide evidence-based explanations regarding the development of hematomas in chest masculinizing surgery and technical considerations for reducing their incidence.

METHODS

A systematic review was conducted to identify all articles related to gender-affirming mastectomy published through September 2021. Literature search yielded 2,661 articles for screening, of which 20 met inclusion criteria. Themes from the selected articles were compiled to generate consensus statements qualified by associated level of evidence (LOE).

RESULTS

The rate of hematoma following gender-affirming mastectomy is reported in the literature ranging from 0% to 31.2%. The use of more limited, nipple-sparing incisions is associated with a higher hematoma rate than mastectomy with free nipple grafting (Level III). There is no conclusive evidence indicating any relationship between the use of masculinizing hormones and the incidence of hematoma (Level IV). Factors such as body mass index (Level III) and breast size (Level III) were not found to influence hematoma risk, though nicotine use (Level IV) was significantly associated with the incidence of hematoma.

CONCLUSIONS

Hematoma is a known complication following gender-affirming mastectomy. The use of limited incision approaches has the strongest association with an increased risk of hematoma. There is no evidence indicating an association between hormone use (i.e., testosterone) and hematoma incidence. Future studies are needed to better define factors, interventions, and protocols to reduce the rate of hematoma.

Spontaneous Near Fatal Hemorrhage into Neurofibromatosis Type 1 Lesion in the Scalp

Neurofibromatosis type 1 (NF1) (von Recklinghausen’s disease) is an autosomal dominant disorder characterized by café-au-lait spots, pigmented hamartomas of the iris, and multiple neurofibromas. Patients can present with hemorrhage secondary to trauma or rarely with spontaneous hemorrhage, both of which can be lethal and life-threatening. We report a 14-year-old girl with a rapidly expanding hematoma in a rare presentation of spontaneous bleed into the NF1 lesion in her scalp. Soon after presentation, she went into hemorrhagic shock. Emergency coiling of the left maxillary artery and branches successfully arrested the bleeding, while resuscitation reversed the hemorrhagic shock.

Effect of intraoperative blood pressure on incidence of hematoma in breast reduction mammoplasty

BACKGROUND

Postoperative hematomas are among the most frequent complications following breast reduction mammoplasty (BRM). Intraoperative hypotension has been implicated in the development of postoperative hematomas following breast reduction. In this study, we performed a retrospective, propensity-matched analysis of patients undergoing primary breast reduction to determine the relationship between intraoperative blood pressure and the development of a postoperative hematoma.

METHODS

A retrospective review of all patients that underwent BRM at a single institution from 2017 to 2019 (n = 563) was conducted. Patients who developed a postoperative hematoma were propensity matched to two controls based on body mass index (BMI) and age. The mean systolic blood pressure (SBP) and average mean arterial pressure (MAP) were recorded for each third of the operation. Data were analyzed using conditional logistic regression.

RESULTS

Thirty-two patients that developed postoperative hematomas were propensity matched to 64 controls. There was no difference in baseline SBP, diastolic blood pressures, or prevalence of hypertension between groups. There was no significant difference in average SBP or MAP between groups. The average MAP during the first third of the procedure was found to be lower in patients who developed a hematoma (69 vs. 72 mmHg), which approached significance at p = 0.08. Closed suction drains were used in 53% of the hematoma group and 78% of the control group (p = 0.02).

CONCLUSION

There does not appear to be an association between intraoperative blood pressure and the incidence of hematoma when comparing patients who developed hematomas after BRM to propensity-matched controls.

Venous thromboembolism chemical prophylaxis after endoscopic trans-sphenoidal pituitary surgery

PURPOSE

There is no compelling outcome data or clear guidance surrounding postoperative venous thromboembolism (VTE) prophylaxis using low molecular weight heparin (chemoprophylaxis) in patients undergoing pituitary surgery. Here we describe our experience of early chemoprophylaxis (post-operative day 1) following trans-sphenoidal pituitary surgery.

METHODS

Single-centre review of a prospective surgical database and VTE records. Adults undergoing first time trans-sphenoidal pituitary surgery were included (2009-2018). VTE was defined as either deep vein thrombosis and/or pulmonary embolism within 3 months of surgery. Postoperative haematomas were those associated with a clinical deterioration together with radiological evidence.

RESULTS

651 Patients included with a median age of 55 years (range 16-86 years). Most (99%) patients underwent trans-sphenoidal surgery using a standard endoscopic single nostril or bi-nostril trans-sphenoidal technique. More than three quarters had pituitary adenomas (n = 520, 80%). Postoperative chemoprophylaxis to prevent VTE was administered in 478 patients (73%). Chemoprophylaxis was initiated at a median of 1 day post-procedure (range 1-5 days postoperatively; 92% on postoperative day 1). Tinzaparin was used in 465/478 patients (97%) and enoxaparin was used in 14/478 (3%). There were no cases of VTE, even in 78 ACTH-dependent Cushing's disease patients. Six patients (1%) developed postoperative haematomas. Chemoprophylaxis was not associated with a significantly higher rate of postoperative haematoma formation (Fisher's Exact, p = 0.99) or epistaxis (Fisher's Exact, p > 0.99).

CONCLUSIONS

Chemoprophylaxis after trans-sphenoidal pituitary surgery on post-operative day 1 is a safe strategy to reduce the risk of VTE without significantly increasing the risk of postoperative bleeding events.

Regional Anesthesia Complications and Contraindications

Regional anesthesia has a strong role in minimizing post-operative pain, decreasing narcotic use and PONV, and, therefore, speeding discharge times. However, as with any procedure, regional anesthesia has both benefits and risks. It is important to identify the complications and contraindications related to regional anesthesia, which patient populations are at highest risk, and how to mitigate those risks to the greatest extent possible. Overall, significant complications secondary to regional anesthesia remain low. While a variety of different regional anesthesia techniques exist, complications tend to fall within 4 broad categories: block failure, bleeding/hematoma, neurological injury, and local anesthetic toxicity.

Risk of hematoma after hemithyroidectomy in an outpatient setting: a systematic review and meta-analysis

Purpose

After thyroid surgery, the overriding concern is the risk of post-thyroid bleeding (PTB). This systematic review and meta-analysis aimed to assess the safety of hemithyroidectomy in an outpatient setting compared to an inpatient setting. The objectives were to (1) find the proportion of PTB in patients scheduled for outpatient hemithyroidectomy, (2) examine if outpatient hemithyroidectomy is clinically safe compared to an inpatient setting and (3) evaluate which selection criteria are most relevant for hemithyroidectomy in an outpatient setting.

Methods

A systematic review was conducted using the following databases: MEDLINE (Ovid), EMBASE (Ovid) and the Cochrane Library from inception until September 2021. We included studies reporting on PTB of patients after hemithyroidectomy in an outpatient setting. The risk of bias was assessed using the Newcastle-Ottawa tool. The results were synthesised using Bayesian meta-analysis. Certainty in evidence was assessed using the GRADE approach.

Results

This review included 11 cohort studies and 9 descriptive studies reporting solely on outpatients resulting in a total of 46,866 patients. PTB was experienced by 58 of the 9025 outpatients (0.6%) and 415 of the 37,841 inpatients (1.1%). There was no difference between the PTB rate of outpatients and inpatients (RR 0.715 CrI [0.396–1.243]). The certainty of the evidence was very low due to the high risk of bias.

Conclusion

The risk of PTB in an outpatient setting is very low, and outpatient hemithyroidectomy should be considered clinically safe. The most relevant selection criteria to consider in outpatient hemithyroidectomy are (1) relevant comorbidities and (2) psycho/-social factors.

Routine Early Computed Tomography Scanner After Laparoscopic Sleeve Gastrectomy in High-Risk Severely Obese Patients Is Effective for Bleeding or Hematoma Diagnosis but not for Staple-Line Leak Detection: a Prospective Study

PURPOSE

Laparoscopic sleeve gastrectomy (LSG) is the most frequently performed bariatric procedure worldwide. Postoperative staple-line leak and intraabdominal hemorrhage can increase associated morbidity and mortality. The value of routine early computed tomography (CT) scanner examination in the early diagnosis of complications in high-risk severely obese patients undergoing LSG is studied.

METHODS

This was a prospective, non-randomized study including all patients undergoing LSG in our department from 2014 to 2020. Patients presenting at least one potential risk factor for postoperative gastric leak and bleeding (as defined by the current literature) were included. Primary endpoint was the efficacy of postoperative day (POD) 2 CT-scanner examination in diagnosing these complications.

RESULTS

One thousand fifty-one high-risk patients were included. Median age was 44 years. Early postoperative surgical complications occurred in 48 patients (4.5%): 25 (2.3%) intraabdominal hemorrhage and 23 (2.2%) staple-line leak. Early CT-scanner detected intraabdominal bleeding or hematoma in 22/25 patients, with 95.6% sensitivity (Youden's index = 0.95), while specificity was 100%, positive predictive value (PPV) 100%, and negative predictive value (NPV) 99.9%. Sensitivity of early postoperative CT-scanner was 43.4% (10/23 patients; Youden's index = 0.43) for staple-line leak detection, with specificity of 100%, PPV 100%, and NPV 98.7%.

CONCLUSION

POD 2 CT-scanner in high-risk severely obese patients undergoing LSG is an excellent tool for early diagnosis of intraabdominal hemorrhage, but sensitivity remains low for staple-line leak detection. Close postoperative clinical follow-up of these patients is essential and any suspicion of postoperative surgical complication should motivate the performance of a CT-scanner.

Eruption Cyst Treated with Diode Laser: A Case Report

Eruption cyst or eruption hematoma is a soft tissue cyst of odontogenic origin that occurs in mucosa, which forms shortly before the eruption of the primary or permanent tooth. It is usually found in children. In some cases, it has been seen that it disappears on its own. If there are complications like pain, bleeding or infection, surgical exposure and drainage are necessary. This case is associated with erupting permanent tooth, and its surgical crown exposure has been done by using a diode laser. How to cite this article: Bansal MB, Kumari A, Asrani KH, et al. Eruption Cyst Treated with Diode Laser: A Case Report. Int J Clin Pediatr Dent 2022;15(2):215-217.

A Shakespearean Dilemma in Breast Augmentation: to Use Drains or not? a Systematic Review : Drains in Breast Augmentation

BACKGROUND

Breast augmentation is one of the most commonly requested and performed plastic surgery procedures. In order to prevent early postoperative complications such as seroma or hematoma, surgical drains could be useful. The aim is to perform a systematic review of the literature on the use of surgical drains in primary breast augmentation.

METHODS

This review was performed following the PRISMA guidelines. PubMed, SCOPUS, Web of Science and Cochrane Library databases were queried in search of clinical studies describing the use of surgical drains in women undergoing primary breast augmentation with implants and documenting seroma and/or hematoma formation rate and/or infection rate.

RESULTS

Initial search identified 2596 studies, and 162 were found relevant. Full-text review and application of our inclusion criteria to all retrieved papers produced 38 articles that met inclusion criteria. Among the included studies, 16 papers reported the use of surgical drains in breast augmentation, while in the remaining 22 articles drains were not used. Only 5 studies specifically investigated the role and effectiveness of surgical drains in augmentation mammaplasty and its possible relationship with complication rate such as seroma, hematoma or infection.

CONCLUSIONS

Despite similar complication rates emerged from the analyzed articles, because of the heterogeneity of the studies, we were not able to demonstrate specifically whether drain use affects the rate of early postoperative complications such as seroma, hematoma and infection. Additional randomized controlled trials are strongly advocated in order to provide the necessary scientific evidence.

The evolution of levator ani muscle trauma over the first 9 months after vaginal birth

INTRODUCTION AND HYPOTHESIS

The objective was to investigate the evolution of levator ani muscle (LAM) trauma over the first 9 months after birth and to evaluate their agreement between different assessment periods.

METHODS

From March 2017 to April 2019 we prospectively evaluated LAM states (intact, hematoma, partial or complete avulsion) of primiparous women after vaginal birth by using 4D translabial ultrasound (TLUS) at three different assessment periods. All women were examined 1-4 days (A1) and 6-10 weeks (A2) postpartum, and women with a trauma additionally 6-9 months postpartum (A3). Cohen's Kappa analysis was performed to evaluate the test agreement between the assessment periods.

RESULTS

Thirty-two percent of the women at A1 had a LAM trauma and 24% at A2. The higher number of LAM injuries at A1 can be explained by hematomas (14%), of which 51% spontaneously resolved at A2, 35% revealed themselves as partial, and 12% as complete avulsions. At A3, we observed anatomical improvement from complete to partial avulsions (23%) and few partial avulsions changed into an intact LAM (3%); none of the complete avulsions changed into an intact LAM. The agreement of 4D TLUS between A1 and A2 was moderate to good (0.64 for the right-sided LAM/0.60 for the left-sided LAM) and between A2 and A3 good to very good (0.76 right-sided/0.84 left-sided).

CONCLUSIONS

Levator ani muscle trauma can reliably be diagnosed during all assessment periods. However, the agreement between A1 and A2 was only moderate to good. This can be explained by hematomas inside the LAM that were only observed early postpartum. We observed some anatomical improvement at A3, but no complete avulsion improved to an intact LAM.

Subamniotic Hemorrhage, a Possible New Presentation of Fetal and Neonatal Alloimmune Thrombocytopenia

BACKGROUND

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare fetal disease in which maternal antibodies directed toward fetal human platelet antigens (HPA) are formed during pregnancy and cause fetal thrombocytopenia. The diagnosis FNAIT is suspected when a fetus or neonate presents with signs of bleeding.

CASE

We describe a pregnancy complicated by a placental hematoma in the 20th week of gestation as the first manifestation of FNAIT. Further evaluation showed signs of germinal matrix hemorrhage and HPA-5b allo-antibodies. After the diagnosis, intravenous immunoglobulin was administered weekly and a healthy daughter was born at 37 weeks. Histopathological analysis revealed that the hematoma was caused by a subamniotic hemorrhage of fetal origin.

CONCLUSION

A subamniotic hematoma appears to be the first manifestation of FNAIT.

Cervical epidural hematoma with Brown-Sequard syndrome caused by an epidural injection: a case report

Epidural hematoma with Brown-Sequard syndrome caused by an epidural injection is a rarely found condition in the emergency department (ED). We report an unusual case of Brown-Sequard syndrome in a 55-year-old man who presented at the ED with right-sided weakness and contralateral loss of pain and temperature sensation after a cervical epidural injection for shoulder pain. Cervicla spine magnetic resonance imaging showed an epidural hematoma from C4 to C6. After admission, his right hemiparesis and contralateral sensory loss improved within eight days, and surgical decompression was not required. Diagnosing spinal lesions in the ED is challenging, especially in patients with acute neurological signs requiring immediate evaluation for stroke. In this case, definite hemiparesis and some contralateral sensory loss were noted. Therefore, a potential spinal lesion was suspected rather than a stroke. This case emphasized the importance of conducting a focused neurological examination after history taking.

Safety and efficacy of emergency transarterial embolization for mesenteric bleeding

Background

Patients with spontaneous or traumatic active mesenteric bleeding cannot be treated endoscopically. Transarterial embolization can serve as a potential alternative to emergency surgery. Literature on transarterial embolization for mesenteric bleeding remains very scarce. The objective of this study was to evaluate the safety and efficacy of transarterial embolization for mesenteric bleeding. We reviewed all consecutive patients admitted for mesenteric bleeding to the interventional radiology department, in a tertiary center, between January 2010 and March 2021. Mesenteric bleeding was defined as mesenteric hematoma and contrast extravasation and/or pseudoaneurysm visible on pre-operative CT scan. We evaluated technical success, clinical success, and complications.

Results

Among the 17 patients admitted to the interventional department for mesenteric bleeding, 15 presented with active mesenteric bleeding requiring transarterial embolization with five patients with hemodynamic instability. Mean age was 67 ± 14 years, including 12 (70.6%) males. Technical success was achieved in 14/15 (93.3%) patients. One patient with technical failure was treated by percutaneous embolization with NBCA-Lipiodol mixture. Three patients (20%) had early rebleeding: two were treated by successful repeat embolization and one by surgery. One patient (6.7%) had early death within 30 days and two patients (13.3%) had late death after 30 days. Mean length of hospitalization was 12.8 ± 7 days. There were no transarterial embolization-related ischemic complications.

Conclusion

Transarterial embolization is a safe and effective technique for treating mesenteric bleeding even in patients with hemodynamic instability. Transarterial embolization doesn’t close the door to surgery and could be proposed as first intention in case of mesenteric bleeding.

Extra dural hematoma following a high voltage electrocution accident: A case report

Electrification accidents is a serious pathology due to the passage of an electric current through the body. The clinical manifestation is mainly represented by skin lesions with burners of different degrees however all the tissues of the body can be affected. The cerebral manifestation is a rare entity described in the literature. In this paper, we report the case of a patient with an electrocution accident manifested by an extradural hematoma who has not encountered a similar case described in the literature. We therefore present this case which poses a poorly understood pathophysiological problem.
