Delayed epistaxis after endoscopic transnasal pituitary tumor resection: clinical characteristics, risk factors, treatment and prevention.

BACKGROUND: Delayed epistaxis after endoscopic transnasal pituitary tumor resection (ETPTR) is a critical complication, tending to cause aspiration or hemorrhagic shock. This study assessed clinical characteristics, risk factors, and provide treatment and prevention advice of this complication. METHODS: This was a retrospective monocentric analysis of 862 patients who underwent ETPTR. Statistical analyses of clinical data revealed the incidence, sources and onset time of delayed epistaxis. Univariate analysis and binary logistic regression were used to identify risk factors. RESULTS: The incidence of delayed epistaxis was 2.78% (24/862), with an average onset time of 20.71 ± 7.39 days. The bleeding sources were: posterior nasal septal artery branch of sphenopalatine artery (12/24), multiple inflammatory mucosae (8/24), sphenopalatine artery trunk (3/24) and sphenoid sinus bone (1/24). Univariate analysis and binary logistic regression analysis confirmed that hypertension, nasal septum deviation, chronic rhinosinusitis and growth hormone pituitary tumor subtype were independent risk factors for delayed epistaxis. Sex, age, history of diabetes, tumor size, tumor invasion and operation time were not associated with delayed epistaxis. All patients with delayed epistaxis were successfully managed through endoscopic transnasal hemostasis without recurrence. CONCLUSIONS: Delayed epistaxis after ETPTR tends to have specific onset periods and risk factors. Prevention of these characteristics may reduce the occurrence of delayed epistaxis. Endoscopic transnasal hemostasis is recommended as the preferred treatment for delayed epistaxis.

Acute epistaxis: a comprehensive overview in the acute care setting.

Epistaxis is a common problem in pediatric patients. Most cases are benign in nature and resolve with minimal intervention. However, there are many unusual conditions that present with epistaxis that can be very serious and should be promptly investigated and treated. This review aids in the distinction between the benign causes of epistaxis and those that are more serious and require further evaluation. The various etiologies of epistaxis are discussed, and recommendations for general and scenario-specific management of pediatric patients with epistaxis are provided.

Telangiectasias, recurrent epistaxis and a strong family history-a case of Osler- Weber-Rendu Syndrome in Pakistan.

Osler-Weber-Rendu syndrome or Hereditary Haemorrhagic Telangiectasia (HHT) is a rare condition, with very few reported cases, especially in Pakistan. As healthcare workers, we encounter multiple cases of recurrent epistaxis in the emergency as well as outpatient departments. However, patients are usually treated symptomatically without a thorough workup. HHT should be considered among the differentials for recurrent epistaxis, as a clinical diagnosis can be made with detailed family history and physical examination. Here is the case of a 58-year-old male who presented to the Gastroenterology OPD, Combined Military Hospital, Lahore, in November 2021, with complaints of generalised weakness and blood in stools. He had a history of recurrent epistaxis and telangiectasias, and further inquiry revealed a strong family history of similar symptoms. He was diagnosed as a case of Osler-Weber- Rendu Syndrome. Informed consent was taken from the patient prior to the writing of the manuscript.

Pediatric Epistaxis-Effectiveness of Conservative Management.

OBJECTIVES: Epistaxis is an emergency medical condition that sometimes requires admission to the emergency department. Pediatric epistaxis differs from epistaxis in the older population in terms of etiology, severity, and management. Our objective was to identify the distinctive features of pediatric epistaxis and determine the appropriate management. METHODS: This was a retrospective study of 231 medical records of children (<18 years old) with epistaxis of a total of 1171 cases in the general population who presented to our medical center's emergency department between 2013 and 2018. RESULTS: Among 231 admissions, 10 children (4.3%) presented more than once. Male patients accounted for the majority of cases (64.5%), and the average age was 9.4 years. Two children were treated with aspirin because of cardiac valve disease. Anterior bleeding was detected in 101 cases (43.7%), whereas posterior origin was observed in 8 cases (3.5%). In 122 cases (52.8%), there was no active bleeding observed. Nose injury was the cause of epistaxis in 24 cases (10.4%), and 16 admissions (6.9%) followed nasal surgical interventions. Nineteen children (8%) had abnormal coagulation tests, and 7 patients (3%) received blood transfusions. Chemical cauterization was performed in 89 cases (39.3%), and anterior packing was needed in only 9 cases (3.9%). Nine children required hospitalization (3.9%), and 2 needed surgical intervention to control bleeding. Compared with the adult population, there were significantly fewer cases of active bleeding, recurrent epistaxis, anterior packing, or need for hospitalization in the pediatric population. CONCLUSIONS: Epistaxis is significantly less severe in the pediatric population, with only a few cases requiring major intervention. Endoscopic examination of the entire nasal cavity and routine coagulation tests are not mandatory unless there is a history of recurrent epistaxis, known coagulopathy, antiplatelet/anticoagulation therapy, or a suspicion of juvenile idiopathic angiofibroma. We suggest using absorbable packs, which offer advantages over cauterization or nonabsorbable packs.

Hereditary hemorrhagic telangiectasia may be the most morbid inherited bleeding disorder in women.

ABSTRACT: Hereditary hemorrhagic telangiectasia (HHT) is the second-most common inherited bleeding disorder (BD) worldwide and remains without approved therapies. HHT causes serious mucosal bleeding resulting in severe iron-deficiency anemia, major psychosocial complications, and visceral arteriovenous malformations in the brain, lung, and liver, which can cause life-threatening hemorrhagic complications. No study has examined the relative morbidity of HHT and von Willebrand disease (VWD), which is the most common inherited BD in women. We performed an observational cohort study of women with HHT or VWD, comparing a representative sample of 100 randomly selected women with HHT to 100 randomly selected age-matched women with VWD. In HHT vs VWD, recurrent epistaxis and gastrointestinal bleeding were more likely (odds ratio [OR], 32.73 [95% confidence interval, 13.81-71.80]; P < .0001 and 5.69 [2.59-12.89]; P < .0001) and heavy menstrual bleeding was less likely (OR, 0.32 [0.18-0.57]; P < .0001). Iron-deficiency anemia was significantly more likely, and the lowest hemoglobin was significantly lower in HHT than in VWD. The odds of iron infusion dependence, requirement for red cell transfusion, and hemostatic surgical procedures were significantly higher-17-fold, threefold, and eightfold higher, respectively-and hospital admissions to manage disease complications were both ∼14 times more frequent in women with HHT vs those with VWD. In conclusion, much higher disease-related morbidity, mortality, and health care use were observed in women with HHT vs VWD, providing evidence that HHT may be the most clinically significant inherited BD in women. Given the vast gap in research funding for HHT compared with both hemophilia (a disease primarily of men) and VWD, these findings have significant implications for gender equity in hematology.

Beware of epistaxis: fatal pseudoaneurysm rupture 30 years after treatment of acromegaly.

We present a fatal complication of treatment in a patient with early-onset acromegaly, treated with two transsphenoidal operations, radiotherapy, radiosurgery and pegvisomant. He was diagnosed in his 30s, and controlled from his 40s, with stable residual tumour within the left cavernous sinus. In his 60s, 30 years after surgery/radiotherapy and 14 years after radiosurgery, he developed recurrent episodes of mild epistaxis. A week later, he presented at his local hospital's emergency department with severe epistaxis and altered consciousness. He was diagnosed with a ruptured internal carotid artery (ICA) pseudoaneurysm, but unfortunately died before treatment could be attempted.ICA pseudoaneurysms are rare complications of surgery or radiotherapy and can present with several years of delay, often with epistaxis. This case highlights the importance of life-long monitoring in patients with previous pituitary interventions and early recognition of epistaxis as a herald sign of a potentially catastrophic event, thus leading to timely treatment.

Preservation or removal of the lateral nasal wall in endoscopic management of maxillary sinus neoplasia: A comparison of approach related morbidity.

BACKGROUND: The endoscopic modified medial maxillectomy (MMM) and prelacrimal approach (PLA) are two routinely performed endoscopic approaches to the maxillary sinus when access via a middle meatal antrostomy is insufficient. However, there is no data in the literature that has compared outcomes and complication profile between the two procedures to determine which approach is superior. OBJECTIVE: To compare the approach related morbidity of PLA and MMM. METHODS: A retrospective cohort study of all consecutive adult patients undergoing either MMM or PLA from 2009 to 2023 were identified. The primary outcome was development of epistaxis, paraesthesia, lacrimal injury, iatrogenic sinus dysfunction within a minimum of 3 months post-operative follow up. RESULTS: 39 patients (44 sides) underwent PLA and 96 (96 sides) underwent MMM. There were no statistically significant differences between the rates of paraesthesia (9.1 % vs 14.6 %, p = 0.367) or prolonged paraesthesia (2.3 % vs 5.2 %, p = 0.426), iatrogenic maxillary sinus dysfunction (2.3 % vs 5.2 %, p = 0.426) or adhesions requiring removal (4.5 % vs 4.2 %, p = 0.918). No cases of epiphora or nasal cavity stenosis occurred in either arm in our study. CONCLUSIONS: According to our data, the endoscopic modified medial maxillectomy and prelacrimal approach are both equally safe approaches with their own benefits to access.

Case report of recurrent epistaxis caused by a live leech in the nasal cavity.

RATIONALE: Epistaxis is one of the common emergencies in otolaryngology. There are many causes of epistaxis, but reports of epistaxis due to nasal foreign bodies like leeches are rare. PATIENT CONCERNS: A 55-year-old male presented with "repeated epistaxis for over 20 days." Nasal endoscopy revealed a live leech in the olfactory area of the left nostril. DIAGNOSES: The patient was diagnosed with epistaxis caused by a live leech in the nasal cavity. INTERVENTIONS: Under nasal endoscopy, the leech was grasped with a vascular clamp and removed from the nasal cavity. The leech measured 8 cm in length. Hemostasis was achieved using a gelatin sponge at the wound site, and the nasal cavity was packed with Vaseline gauze. OUTCOMES: The live leech was removed via nasal endoscopy. Two days later, the Vaseline gauze packing was removed, and the patient experienced no further nasal bleeding. CONCLUSION: Live leeches in the nasal cavity can cause epistaxis. Nasal endoscopic removal of the live leech is an effective treatment. LESSON: There are many causes of epistaxis, which are nonspecific and prone to missed or incorrect diagnosis. In patients with a history of fieldwork or direct contact with leeches who present with recurrent nasal bleeding, the possibility of epistaxis caused by a live leech should be considered, and timely and effective treatment should be provided.

Intravascular papillary endothelial hyperplasia of the maxillary sinus extending into the contralateral nasal cavity.

INTRODUCTION: Intravascular papillary endothelial hyperplasia (IPEH) predominantly occurs in the subcutaneous and dermal regions and rarely originates from the sinonasal mucosa. CASE PRESENTATION: We report on the case of a 58-year-old male patient who presented with progressive bilateral nasal obstruction, left-sided epiphora, and intermittent epistaxis. Computed tomography revealed a soft tissue opacity in the left maxillary sinus with intersinusoidal nasal wall demineralization, extending into the surrounding ethmoid cells and the right nasal cavity through a contralateral deviation of the nasal septum. Contrast-enhanced T1-weighted magnetic resonance imaging further confirmed these findings. The IPEH originating from the maxillary sinus extended into the contralateral nasal cavity, and it was successfully removed using an endoscopic endonasal approach, avoiding overly aggressive treatment. CONCLUSION: This case report highlights the diagnostic challenges of IPEH in the sinonasal region and the importance of considering IPEH as a differential diagnosis in patients presenting with nasal obstruction, epiphora, and intermittent epistaxis.

Severe epistaxis after posterior nasal nerve ablation requiring surgical intervention: A multi-center case series.

KEY POINTS: Severe epistaxis occurs in 2% of PNN ablation cases, independent of method or device type. Major epistaxis requiring intervention after PNN ablation can occur on average 20 days post-procedure.

Severe unilateral refractory epistaxis arising from the septal branch of the anterior ethmoid artery.

KEY POINTS: The septal branch of the anterior ethmoid artery (sbAEA) is an underrecognized source of severe refractory epistaxis. Herein, we describe the presentation, predisposing factors, treatment strategies, and outcomes of a series of patients with this condition.

Maxillofacial haemorrhagic symptoms in emergency department patients: impact of antithrombotics.

PURPOSE: To investigate the effect of antithrombotics on the occurrence of maxillofacial haemorrhagic symptoms, and to determine if these haemorrhagic symptoms are predictors of maxillofacial fractures. METHOD: A prospective cohort study was conducted of consecutive patients with maxillofacial trauma who had been admitted to the emergency department of four hospitals in the Netherlands. This study compared five haemorrhagic symptoms (peri-orbital haematoma, raccoon eyes, epistaxis, subconjunctival ecchymosis, and intra-oral haematoma) between patients not-using (NUA) and using (UA) of antithrombotics, and whether these maxillofacial haemorrhagic symptoms served as predictors for maxillofacial fractures. RESULTS: Out of the 1005 patients, 812 (81%) belonged to the NUA group, and 193 (19%) to the UA group. UA patients exhibited higher frequencies of peri-orbital hematoma (54% vs. 39%, p < 0.001), raccoon eyes (10% vs. 5%, p = 0.01), and subconjunctival ecchymoses (16% vs. 7%, p < 0.001). In NUA, peri-orbital hematoma (OR = 2.5, p < 0.001), epistaxis (OR = 4.1, p < 0.001), subconjunctival ecchymosis (OR = 2.3, p = 0.02), and intra-oral hematoma (OR = 7.1, p < 0.001) were significant fracture predictors. Among UA, peri-orbital hematoma (OR = 2.2, p = 0.04), epistaxis (OR = 5.4, p < 0.001), subconjunctival ecchymosis (OR = 3.7, p = 0.008), and intra-oral hematoma (OR = 22.0, p < 0.001) were significant fracture predictors. CONCLUSION: Maxillofacial haemorrhagic symptoms were observed more frequently in the UA group than in the NUA group. However, in both groups, maxillofacial haemorrhagic symptoms appear to be predictors of maxillofacial fractures. Caution is warranted in attributing these symptoms solely to antithrombotic use during emergency department assessments.

Double jeopardy, glomangiopericytoma and Glanzmann thrombasthenia resulting in recurrent epistaxis: a case report.

Glanzmann thrombasthenia is a rare bleeding disorder induced by inherited defects of the platelet membrane αIIbß3 glycoprotein. Glomangiopericytoma, on the other hand, is a very rare sinonasal tumor demonstrating a perivascular myoid phenotype. We herein report the first described case in the literature of Glanzmann thrombasthenia and glomangiopericytoma. The patient is a 40-year-old man diagnosed with type 1 Glanzmann thrombasthenia who presented with repetitive and profuse posterior epistaxis initially managed with platelet transfusions and recombinant activated factor VII (rFVIIa). Due to the unresolved epistaxis, nasal endoscopy was performed revealing a vascularized tumor. Subsequently, a sphenopalatine artery embolization followed by a surgical excision of the tumor was performed. The pathology report diagnosis of the tumor was glomangiopericytoma. This case sheds the lights on a very rare cause of epistaxis in a patient with Glanzmann thrombasthenia, with a challenging multidisciplinary management. A local cause of epistaxis should always be considered even in case of a diagnosed bleeding disorder, especially when the bleeding is recurrent.

Epistaxis and Facial Swelling Due to Nasal Blastomycosis in a Cat.

A 5 yr old castrated male domestic longhair was examined because of left-sided facial swelling and epistaxis. Head computed tomography with contrast identified a mass within the left nasal cavity and multifocal regions of nasal bone osteolysis. Histopathology of nasal mass biopsies and cytology of the facial swelling revealed pyogranulomatous inflammation due to Blastomyces dermatitidis. The cat experienced resolution of clinical signs following 8 mo of treatment with itraconazole. Although rare, clinicians should include blastomycosis on the differential diagnoses list of infectious causes for feline nasal disease if within an endemic area.

Environmental Risk Factors for Pediatric Epistaxis vary by Climate Zone.

INTRODUCTION AND OBJECTIVE: Prior studies have provided variable results regarding environmental risk factors for epistaxis. These studies were conducted in varying climate zones, which may explain discrepancies in results. The objective of this study is to investigate correlations between season, temperature, and humidity on frequency of pediatric epistaxis across climate zones. METHODS: Children seen in the outpatient setting for epistaxis were identified from the 2007-2010 IBM MarketScan database. Climate zones were assigned according to International Energy Conservation Code (IECC) classification, where temperature zones in the United States and territories were assigned on an ordinal scale from 1 (tropical) to 8 (subarctic), and humidity zones were categorized as moist, dry, or marine. The control population was a sample of all well-child visits matched by age and county. RESULTS: We identified 184,846 unique children seen for epistaxis and 1,897,012 matched controls. Moderate temperature zones were associated with lower odds of epistaxis compared with the hottest and coldest zones. Humidity was associated inversely with epistaxis rates in moderate temperature zones but was not a significant predictor of epistaxis in climates with extreme heat. Additionally, summer was associated with lower odds of epistaxis compared to winter. Interestingly, however, there were significantly higher rates of cautery procedures during summer months, driven largely by increased procedures performed in clinic, as opposed to the operating room or emergency room. CONCLUSIONS: Environmental risk factors for epistaxis vary by climate zone. The model presented reconciles prior reports and may allow for more personalized clinical management based on regional climate. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1450-1456, 2024.

Influence of meteorological variables on the frequency of visits and hospital admission for epistaxis in a city with a cold semi-arid climate (Lorca, Spain).

BACKGROUND AND OBJECTIVES: Epistaxis is a common emergency for otorhinolaryngologists. Although the aetiological factors have been widely studied, they remain subject to debate. The role of meteorological variables has been discussed in recent years, but results have been inconsistent. Given a lack of prior data, the aim of our study was to identify the meteorological variables that influence the frequency of visits and hospital admission for epistaxis in a city with a cold semi-arid climate in Spain. METHODS: Case-control study. CASES: patients who attended the accident and emergency department of a secondary level hospital for epistaxis over a 9-year period (2011-2019). Controls were established by simple random sampling among emergency rooms visits in general (patients who attended the same centre over the same period of time). Sociodemographic, clinical and meteorological variables were all taken into account. RESULTS: 2749 patients in the epistaxis group and 2764 in the control group. There were significant differences in the epistaxis group, with a higher proportion of male (62.85%) and older patients. Univariate and multivariate analysis revealed that the daily minimum temperature and maximum wind speed were factors significantly associated with the onset of epistaxis. In addition, logistic regression analysis showed that decreases in minimum temperature and increases in maximum wind speed were associated with an increase in epistaxis (p < 0.01). No association was found between hospital admission and the weather conditions. CONCLUSION: Our findings suggest that low minimum temperatures and high wind speeds are associated with the number of visits to hospital accident and emergency departments for epistaxis, but not with hospital admission.
