The use of a nasal obturator in hereditary haemorrhagic telangiectasia: an alternative to Young's procedure

Long-term efficacy assessment of current treatment options for epistaxis in HHT

Purpose

Hereditary hemorrhagic telangiectasia (HHT) is a vascular disorder that presents with recurrent, intractable epistaxis. The aim of this study was to retrospectively analyze the efficacy of various treatment options for epistaxis in patients with HHT, over a period of 18 years, and to correlate these findings with available evidence in the literature.

Methods

Records of patients with HHT, treated for epistaxis between 2000 and 2018 were analyzed. Treatment procedures carried out and their efficacy were extracted and analyzed.

Results

Forty-three records were evaluated. All patients were given nasal humidifying ointments, 93% required acute treatment with bipolar electrocautery, and 60% underwent atraumatic nasal packing. Recurrent cases were treated medically with tranexamic acid (26%), oestrogen (19%), and bevacizumab (2%). Laser photocoagulation was done in selected cases (40%) and if unsuccessful, septal dermoplasty was performed (2.3%). Endovascular embolization was reserved for life-threatening emergencies (7%).

Conclusion

Epistaxis in HHT is not curable, but can be managed by employing a comprehensive stepwise approach. An algorithm for effective and comprehensive management has been presented.

The Effect of Treatment for Epistaxis Secondary to Hereditary Hemorrhagic Telangiectasia

Background

Epistaxis is the most common symptom in patients with hereditary hemorrhagic telangiectasia. Different treatment options have been described but with little reference to their effect on quality of life or disease severity.

Methods

This study prospectively investigated the effect of nasal closure, argon laser, and a combination of septodermoplasty and argon laser treatments on quality-of-life scores and disease severity ratings in a group of 29 patients with moderate to severe epistaxis referred to a tertiary referral center.

Results

The only group of patients who showed a significant improvement (p < 0.05) in quality of life were those who underwent nasal closure. In addition, the nasal closure patients were the only group in which there was a complete cessation of bleeding.

Conclusion

Nasal closure should be offered to patients with moderate to severe epistaxis secondary to hereditary hemorrhagic telangiectasia that has proved unresponsive to other treatment.

Epistaxis in hereditary hemorrhagic telangiectasia: an evidence based review of surgical management

Patients with Hereditary Hemorrhagic Telangiectasia (HHT) frequently present with epistaxis. Up to 98 % of these patients will have epistaxis at some point in their life. There are multiple ways to deal with this problem, including conservative, medical and surgical options. We present a case and an update on the treatment options for HHT, with a focus on the newer and experimental techniques.

How to manage patients with hereditary haemorrhagic telangiectasia

Hereditary haemorrhagic telangiectasia is a rare systemic autosomal dominantly inherited disorder of the fibrovascular tissue with a wide variety of clinical manifestations. Diagnosis is based on the clinical Curaçao criteria or molecular genetic testing. Dilated vessels can develop into telangiectases or larger vascular malformations in various organs, calling for an interdisciplinary approach. Epistaxis and gastrointestinal bleeding can result from these vascular defects. Various conservative and interventional treatments have been described for these conditions. However, no optimal therapy exists. Treatment can become especially difficult due to progressive anaemia or when anticoagulant or anti-thrombotic therapy becomes necessary. Screening for pulmonary arteriovenous malformations (PAVM) should be performed in all confirmed and suspected patients. Treatment by percutaneous transcatheter embolotherapy and antibiotic prophylaxis is normally effective for PAVM. Cerebral or hepatic vascular malformations and rare manifestations need to be evaluated on a case-by-case basis to determine the best course of action for treatment.

Evidence-based management of epistaxis in hereditary haemorrhagic telangiectasia

BACKGROUND

There are currently no guidelines in the UK for the specific management of hereditary haemorrhagic telangiectasia related epistaxis. The authors aimed to review the literature and provide an algorithm for the management of hereditary haemorrhagic telangiectasia related epistaxis.

METHOD

The Medline and Embase databases were interrogated on 15 November 2013 using the search items 'hereditary haemorrhagic telangiectasia' (title), 'epistaxis' (title) and 'treatment' (title and abstract), and limiting the search to articles published in English.

RESULTS

A total of 46 publications were identified, comprising 1 systematic review, 2 randomised, controlled trials, 27 case series, 9 case reports, 4 questionnaire studies and 3 in vitro studies.

CONCLUSION

There is a lack of high-level evidence for the use of many of the available treatments for the specific management of epistaxis in hereditary haemorrhagic telangiectasia. Current management should be based on a multidisciplinary team approach involving both a hereditary haemorrhagic telangiectasia physician and an ENT surgeon, especially when systemic therapy is being considered. The suggested treatment algorithm considers that the severity of epistaxis merits intervention at different levels of the treatment ladder. The patient should be assessed using a reproducible validated assessment tool, for example an epistaxis severity score, to guide treatment. More research is required, particularly in the investigation of topical agents targeting the development and fragility of telangiectasiae in hereditary haemorrhagic telangiectasia.

Management of severe epistaxis after Young's procedure: a case report

BACKGROUND

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder affecting multiple organ systems, with epistaxis being the most common manifestation. Multiple procedures have been used for the management of epistaxis in the setting of HHT, including closure of the anterior nares via a Young's procedure. While this procedure results in loss of smell and permanent nasal obstruction, proponents note significant improvement in patient symptomatology.

METHODS

Case report.

RESULTS

A 70-year-old female with a history of HHT presented to an outside hospital with bleeding into the nasopharynx 2 months after undergoing a modified Young's procedure at an unaffiliated institution. She was transfused with 2 units of packed red blood cells (PRBCs) and transferred to our facility. Due to persistent epistaxis and need for airway protection, the patient was intubated and her throat was packed. She also developed aspiration pneumonia and hypotensive shock requiring vasopressors. Twenty-four hours following bilateral internal maxillary and sphenopalatine artery embolization, she developed significant epistaxis requiring reversal of the Young's procedure on the left and placement of an anterior-posterior pack at the bedside. Upon packing removal several days later in the operating room, she was noted to have significant bleeding that necessitated reversal of the Young's procedure on the right side to obtain adequate exposure and hemostasis.

CONCLUSION

We report a case of significant, life-threatening epistaxis following a modified Young's procedure that requiring multiple transfusions, bilateral embolization, and ultimately reversal of the Young's procedure for control of epistaxis. Although recognized as a potential complication, to our knowledge this is the first report in the English literature of such a case.

Hereditary hemorrhagic telangiectasia-related epistaxis: innovations in understanding and management

BACKGROUND

Epistaxis is the most common manifestation of hereditary hemorrhagic telangiectasia (HHT), affecting approximately 90% of patients at some point during their lifetime. Bleeding is chronic and varies from mild, self-limited episodes to severe, transfusion-dependent or life-threatening epistaxis. Treatment options vary from conservative, nonsurgical management to more aggressive surgical approaches. A number of treatment options have been introduced in recent years. There is little consensus in the literature regarding treatment algorithms. The objective of this investigation was to provide a contemporary review of HHT-related epistaxis, including pathophysiology, disease manifestations, and state-of-the-art treatment modalities.

METHODS

A systematic review of the literature for HHT-related epistaxis was performed using the search terms "hereditary hemorrhagic telangiectasia" and "epistaxis." Additional literature search regarding current recommendations for HHT evaluation and recent developments in genetic mechanisms, pathophysiology, and treatment of HHT was also performed.

RESULTS

A total of 308 articles were identified and reviewed for appropriateness of inclusion whereas 64 articles met inclusion criteria. Treatment options range from topical and hormonal therapy to more aggressive surgical modalities. Most treatment descriptions are case series, with few randomized controlled trials. A number of new and novel therapies have been introduced in recent years.

CONCLUSION

HHT is a heterogeneous disease requiring multidisciplinary evaluation and treatment. Therapeutic options for HHT-related epistaxis vary from conservative, nonsurgical measures to more aggressive surgical treatments. A graduated treatment plan is recommended. Patients present with a wide degree in variation of severity of epistaxis, and treatment is best tailored to the individual patient.

Hereditary hemorrhagic telangiectasia: an overview of diagnosis, management, and pathogenesis

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is a disorder of development of the vasculature characterized by telangiectases and arteriovenous malformations in specific locations. It is one of most common monogenic disorders, but affected individuals are frequently not diagnosed. The most common features of the disorder, nosebleeds, and telangiectases on the lips, hands, and oral mucosa are often quite subtle. Optimal management requires an understanding of the specific presentations of these vascular malformations, especially their locations and timing during life. Telangiectases in the nasal and gastrointestinal mucosa and brain arteriovenous malformations generally present with hemorrhage. However, complications of arteriovenous malformations in the lungs and liver are generally the consequence of blood shunting through these abnormal blood vessels, which lack a capillary bed and thus result in a direct artery-to-vein connection. Mutations in at least five genes are thought to result in hereditary hemorrhagic telangiectasia, but mutations in two genes (ENG and ACVRL1/ALK1) cause approximately 85% of cases. The frequency of arteriovenous malformations in particular organs and the occurrence of certain rare symptoms are dependent on the gene involved. Molecular genetic testing is used to establish the genetic subtype of hereditary hemorrhagic telangiectasia in a clinically affected individual and family, and for early diagnosis to allow for appropriate screening and preventive treatment.

A natural obturator in hereditary haemorrhagic telangiectasia

OBJECTIVE

Most patients with hereditary haemorrhagic telangiectasia suffer with frequent episodes of epistaxis. The aim of this case report is to highlight the effect on epistaxis, occurring in hereditary haemorrhagic telangiectasia, when nasal airflow ceases.

CASE REPORT

We present the interesting case of a patient with hereditary haemorrhagic telangiectasia who experienced cessation of her recurrent, refractory epistaxis through the development of coexisting polyp disease. The patient's enlarged, grade three nasal polyps were behaving as physiological obturators, limiting airflow through her nose. This reduced the intranasal trauma and subsequent frequency of her nosebleeds.

CONCLUSION

Epistaxis is a debilitating part of hereditary haemorrhagic telangiectasia, and poses a frequent management challenge. Our patient was more tolerant of her grade three nasal polyps than of her recurrent epistaxis. This case highlights the importance of reducing nasal airflow when treating patients with hereditary haemorrhagic telangiectasia.

Epistaxis in patients with hereditary hemorrhagic teleangiectasia

Introduction. Spontaneous recurrent epistaxis is the most common clinical manifestation of hereditary hemorrhagic teleangiectasia (HHT). It occurs in more than 90% of HHT patients and is the most distressing symptom. Nasal teleangiectasias tend to increase with age both in size and number, so epistaxis is heavier and more frequent. For patients with mild to moderate disease, there are many adequate treatment options. For those with severe disease, most treatments offer just a hemorrhage-free interval. Experienced otorhinolaryngologists who treat epistaxis in these patients often use the adage "to do as little as possible for as long as possible". Management of acute epistaxis. The recommendations for the management of acute epistaxis include: compression, use of topical antifibrinolytics, laser therapy, argon plasma coagulation therapy, fibrin sealant spray or gelatin sponge soaked in adrenaline. In cases of heavy acute epistaxis, an epistaxis balloon combined with artery ligation and/or embolization is the most effective treatment. Nasal packing and electrocauterisation should be avoided to prevent further trauma to the blood vessels. Treatment of recurrent epistaxis. Management of recurrent epistaxis includes topical application of laser energy (argon, Nd: YAG, KTP/532 and diode, not CO2), argon plasma coagulation in combination with 0.1% estriol ointment, caustics, antifibrinolytics, bleomycin and sclerosing substances. Systemic estrogen-progesterone at doses used for oral contraception may eliminate bleeding in women with heavy epistaxis. Systemic antifibrinolitics (used with extreme precaution) and septal dermoplasty give good results. The only method which successfully and permanently solves the problem of severe refractory epistaxis in hereditary hemorrhagic teleangiectasia is closure of the nasal cavities. .
