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.

Knowledge and awareness of the Saudi general public toward epistaxis: a cross-sectional study.

Background: Epistaxis is one of the most common ear, nose, and throat (ENT) emergencies that present to the emergency or primary care centers. Study aim: This study aimed to assess the knowledge of the Saudi general public toward epistaxis. Methods: This study adopted a cross-sectional analytical study design. The questionnaire link was distributed using social media channels. The participants were adult Saudi nationals that live in Saudi Arabia. The data was collected using a self-administered questionnaire that assessed knowledge related to epistaxis. The knowledge score was calculated using the 10 knowledge evaluation questions. Each correct response was assigned a value of "one." The scores ranged from "zero" to "ten," with higher scores signifying greater knowledge. A percentage score was computed, and the participants' knowledge was classified as poor (% score: ≤50%), moderate (% score: 51 to 70%), and good (% score: 71 to 100%). Statistical Package for Social Sciences (SPSS) version 26 was used for statistical analysis. Results: The study included 452 participants of whom 70.1% were females. Married individuals comprised 60.8% of the sample. The prevalence of self-reported epistaxis was 43.6% in the last 6 months. Among the participants, 42.9%, had "Poor" knowledge score, followed by 39.6% who had "moderate" score, and 17.5% had "Good" score. These results show that most participants had poor to moderate knowledge, with a minority demonstrating a good level of knowledge. All demographic variables have significantly influenced the adequacy of knowledge about epistaxis. Furthermore, participants who believed that the general public has insufficient knowledge on epistaxis had a significantly lower knowledge score (p = 0.001). Conclusion: The present study found a non-satisfactory, low-to-moderate knowledge level of the Saudi general public toward epistaxis. We propose emphasizing public knowledge and education about first aid for epistaxis because proper first aid can minimize significant complications when done properly.

Sphenopalatine artery pseudoaneurysm masquerading as a second primary maxillary carcinoma.

PURPOSE: Maxillary sinus carcinomas usually present as a locally advanced disease at the time of diagnosis and it is extremely unusual to have a second primary maxillary carcinoma on the contralateral side after many years of completion of treatment of the first malignancy. We present here a case report of a sphenopalatine artery (SPA) pseudoaneurysm mimicking the second primary maxillary carcinoma. METHODS: We reviewed the literature for SPA pseudoaneurysm. RESULTS/CASE REPORT: This report describes the case of a 90-year-old man with a background of adenoid cystic carcinoma of the right maxillary sinus, diagnosed and treated with surgery and radiotherapy 14 years ago, who presented with a history of multiple episodes of epistaxis. The radiological evaluation showed a heterogeneously enhancing mass with a central hemorrhagic component and surrounding bony erosions in the left maxillary sinus and the patient was planned for biopsy from the suspicious mass along with SPA ligation. However, on opening the maxillary antrum there was excessive bleeding and it was determined unsafe to proceed further. The patient was subsequently taken to interventional radiology for diagnostic angiography which revealed an SPA pseudoaneurysm that was subsequently embolized successfully. CONCLUSIONS: Sphenopalatine artery pseudoaneurysms should be considered as a differential for recurrent epistaxis in patients with a history of sinonasal malignancy. In such cases, endovascular embolization is a viable management option.

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.

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.

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.

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.

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.

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.

A randomized comparison of three intubation techniques/tube materials for nasotracheal intubation.

PURPOSE: We sought to compare three intubation methods using different intubation techniques/tube materials for tube advancement from the nasal cavity into the oral cavity during nasotracheal intubation. METHODS: We conducted a randomized clinical trial with adult patients scheduled to undergo elective surgery requiring nasotracheal intubation for general anesthesia. Participants were randomly allocated to a polyvinyl chloride (PVC) tube group (group P), PVC tube attached to a rubber catheter group (group PR), or velvet-soft PVC tube group (group V). Tracheal intubation was then performed based on group allocation. The primary outcome was the first-attempt success rate of tube advancement into the oral cavity; secondary outcomes included the time required for tube advancement into the oral cavity, total intubation time, and the incidence of epistaxis. RESULTS: A total of 149 patients were included in the study. The first-attempt success rate in group V (90%) was significantly higher than that in group P (58%) (odds ratio, 6.5; 95% confidence interval [CI], 2.2 to 19.2), but similar to that in group PR (100%). The mean (standard deviation) time required for tube advancement into the oral cavity was significantly shorter in group V (16 [13] sec) than in group PR [40 (10) sec; 95% CI of mean difference, 17 to 30] and group P (26 [16] sec; 95% CI of mean difference, 3 to 16). Total intubation time was longest in group PR. Epistaxis occurred the least in group V. CONCLUSIONS: Among the three intubation techniques/tube materials for nasotracheal intubation, the velvet-soft PVC tube provided the highest first-attempt success rate, most expeditious advancement into the oral cavity, and lowest incidence of epistaxis. STUDY REGISTRATION: ClinicalTrials.gov (NCT04695444); first submitted 30 December 2020.

RéSUMé: OBJECTIF: Nous avons cherché à comparer trois méthodes d'intubation utilisant différentes techniques d'intubation / matériaux de sondes pour l'avancement de la sonde de la cavité nasale dans la cavité buccale pendant l'intubation nasotrachéale. MéTHODE: Des patient·es devant recevoir une intubation nasotrachéale ont été réparti·es au hasard dans un groupe avec sondes en polychlorure de vinyle (PVC) (groupe P), un groupe avec sondes en PVC attachées à un cathéter en caoutchouc (groupe PR) ou un groupe avec sondes en PVC doux comme du velours (groupe V). L'intubation trachéale a ensuite été réalisée en fonction de l'affectation du groupe. Le critère d'évaluation principal était le taux de réussite de la première tentative d'avancement de la sonde dans la cavité buccale; les critères d'évaluation secondaires comprenaient le temps nécessaire à l'avancement de la sonde dans la cavité buccale, la durée totale de l'intubation et l'incidence d'épistaxis. RéSULTATS: Au total, 149 patient·es ont été inclus·es dans l'étude. Le taux de réussite de l'intubation à la première tentative était significativement plus élevé dans le groupe V (90 %) que dans le groupe P (58 %) (rapport de cotes, 6,5; intervalle de confiance à 95 % [IC], 2,2 à 19,2), mais similaire à celui du groupe PR (100 %). Le temps moyen (écart type) nécessaire pour l'avancement de la sonde dans la cavité buccale était significativement plus court dans le groupe V (16 [13] sec) que dans le groupe PR (40 [10] sec; IC 95 % de la différence moyenne, 17 à 30) et dans le groupe P (26 [16] sec; IC 95 % de la différence moyenne, 3 à 16). La durée totale d'intubation était la plus longue dans le groupe PR. C'est dans le groupe V que l'épistaxis a été la moins fréquente. CONCLUSION: Parmi les trois techniques d'intubation/matériaux de sonde pour l'intubation nasotrachéale, le tube en PVC doux comme du velours a fourni le taux de réussite de première tentative le plus élevé, l'avancement le plus rapide dans la cavité buccale et l'incidence d'épistaxis la plus faible.

Nasal Disorders.

Nasal obstruction, rhinorrhea, and epistaxis are common presenting concerns in primary care clinics. Nasal disorders affect the quality of life for many children and families. Rarely, these complaints may represent a life-threatening condition among infant obligate nasal breathers or cases of unusual pathology. The most common causes of rhinorrhea and nasal obstruction vary by age and include physiologic, infectious, allergic, foreign body, irritant, and traumatic causes. Less commonly, children may have congenital malformations, sinonasal masses, or autoimmune disease. The most common causes of epistaxis are inflammatory, environmental, and traumatic causes and medication misuse, but rarely, children may have predisposing anatomic, hematologic, or vascular abnormalities or even sinonasal tumors. In this article, we provide a thorough review of the common nasal disorders treated every day in primary care clinics and mention briefly some of the rare but serious cases that may be overlooked without considering a full differential diagnosis.

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.

Usefulness of endoscopic endonasal underwater surgery using a combination of coblation and a lens-cleaning system for hemostasis in hereditary hemorrhagic telangiectasia.

Hemostatic procedures for controlling nasal bleeding in refractory diseases such as hereditary hemorrhagic telangiectasia (HHT) can be challenging. In this report, we present a novel technique for underwater endoscopic endonasal hemostatic surgery, which was performed on a 69-year-old man with HHT. The patient had been experiencing frequent episodes of nasal bleeding and had many telangiectasias in the nasal cavity, which were the cause of the bleeding. These telangiectasias were effectively treated using a coblation device in combination with an endoscope lens-cleaning system that supplied saline to create stable underwater conditions. There are several advantages to this technique, including provision of a stable and clear endoscopic field of view, allowing for better visualization of the surgical site. This makes it easier to identify bleeding points and ensure accurate hemostasis. Additionally, the hydrostatic pressure created by the underwater environment helps to reduce bleeding during the procedure. However, it is important to take careful precautions to prevent water from entering the lower airway. With this precautionary measure, this technique is particularly useful in managing bleeding in patients with HHT.

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.

Risk Factors and Management Outcomes in Pediatric Epistaxis at an Emergency Department.

BACKGROUND: Most cases of pediatric epistaxis are spontaneous and self-resolve. However, a subset of children may experience significant bleeding and require procedural or medical intervention. OBJECTIVE: We aim to identify risk factors associated with moderate and severe epistaxis in the emergency department (ED) and explore management outcomes. METHODS: We retrospectively reviewed all patients under 22 years old with epistaxis who presented to our ED between 2013 and 2022. Epistaxis severity was defined as mild (required nasal compression or intranasal medications), moderate (required cautery or packing), or severe (required factor replacement, transfusion, hospital admission, or surgery). We performed univariable and multinomial regression analyses, with risk factors and outcomes analyzed according to severity. RESULTS: Of 858 visits, 41 (5%) patients had moderate and 67 (8%) had severe epistaxis. Patients with moderate epistaxis were older than those with mild and severe epistaxis (median 15.6 vs. 8.3 vs. 10.7 years, p < 0.001). In regression analysis, moderate epistaxis was associated with older age, prior ED visit within 72 h, and antiplatelet medication use (p < 0.01). Severe epistaxis was associated with bleeding disorders, nasal procedures within 30 days, and anticoagulation medication use (p ≤ 0.001). Bleeding over 30 min prior to arrival was associated with both moderate and severe epistaxis (p < 0.05). Of the 67 patients with severe epistaxis, 10 (15%) required factor replacement, 28 (42%) required transfusion, 52 (77%) required hospital admission, and 5 (7%) underwent surgery. CONCLUSION: Epistaxis severity is associated with certain risk factors. However, most cases of pediatric epistaxis are mild and do not require intervention or ED evaluation.

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.
