Airway compromise secondary to lingual hematoma complicating administration of tissue plasminogen activator for acute ischemic stroke

Spontaneous lingual and sublingual haematoma: a rare complication of warfarin use

Warfarin is commonly used for prevention of embolic events. Bleeding is the main side effect of warfarin. Lingual and sublingual haematoma are rare. In the literature, nine cases have so far been reported. We report the case of a 70-year-old Caucasian woman who developed spontaneous lingual and sublingual haematomas while on warfarin therapy. Spontaneous lingual and sublingual haematoma are rare, but can be potentially life-threatening complications as they cause airway obstruction. To the best of our knowledge, this is the first reported case of earliest haematoma after warfarin use.

Lingual Haematoma due to Tenecteplase in a Patient with Acute Myocardial Infarction

The use of intravenous thrombolytic agents has revolutionised the treatment of acute myocardial infarction. However, the improvement in mortality rate achieved with these drugs is tempered by the risk of serious bleeding complications, including intracranial haemorrhage. Tenecteplase is a genetically engineered mutant tissue plasminogen activator. Haemorrhagic complications of tissue plasminogen activator (tPA) are well known. Compared to other tPAs, tenecteplase use leads to lower rates of bleeding complications. Here, we report a case of unusual site of spontaneous bleeding, intralingual haematoma during tenecteplase therapy following acute myocardial infarction, which caused significant upper airway obstruction and required tracheotomy to maintain the patient's airway. Clinical dilemmas related to securing the airway or reversing the effects of tissue plasminogen activator are discussed.

Airway trauma in a high patient volume academic cardiac electrophysiology laboratory center

BACKGROUND

Providing anesthesia and managing airways in the electrophysiology suite can be challenging because of its unique setting outside of the conventional operating room. We report our experience of several cases of reported airway trauma including tongue and pharyngeal hematoma and vocal cord paralysis in this setting.

METHODS

We analyzed all of the reported airway trauma cases between December 2009 and January 2011 in our cardiac electrophysiology laboratories and compared these cases with those without airway trauma. Data from 87 cases, including 16 cases with reported airway trauma (trauma group) and 71 cases without reported airway trauma from the same patient population pool at the same period (control group), were collected via review of medical records.

RESULTS

Airway trauma was reported for 16 patients (0.7%) in 14 months among 2434 anesthetic cases. None of these patients had life-threatening airway obstruction. The avoidance of muscle relaxants during induction in patients with a body mass index less than 30 was found to be a significant risk factor for airway trauma (P = 0.04; odds ratio, 10; 95% confidence interval, 1.1-482). Tongue or soft tissue bite occurred in 2 cases where soft bite block was not used during cardioversion. No statistically significant difference was found between the trauma and the control groups for preprocedure anticoagulation, anticoagulation during the procedure, or reversal of heparin at the end of the procedure.

CONCLUSIONS

The overall incidence of reported airway trauma was 0.7% in our study population. Tongue injury was the most common airway trauma. The cause seems to have been multifactorial; however, airway management without muscle relaxant emerged as a potential risk factor. Intubation with muscle relaxant is recommended, as is placing a soft bite block and ensuring no soft tissue is between the teeth before cardioversion.

Angioedema after tPA: what neurointensivists should know

BACKGROUND

Angioedema is an underappreciated and potentially life-threatening complication of intravenous (IV) recombinant tissue plasminogen activator (rt-PA). Patients taking angiotensin converting enzyme (ACE) inhibitors are at increased risk of this rare complication.

METHODS

Case report.

RESULTS

A 74 year-old woman taking lisinopril for hypertension was treated with IV rt-PA for right hemispheric acute ischemic stroke. Shortly after completion of the rt-PA infusion, she developed asymmetric angioedema involving the tongue and left lower lip. No emergent airway intervention was needed. Following treatment with epinephrine, antihistamines, and corticosteroids, the edema resolved within 24 h. The patient made an excellent recovery from the ischemic stroke.

CONCLUSIONS

Orolingual angioedema can complicate rt-PA treatment of acute stroke and is often ipsilateral to the side of hemiparesis. Neurointensivists should be aware of this possibility, which is increased in patients taking ACE inhibitors. Epinephrine can be given safely in this scenario. Identification of high risk features may help guide decisions regarding early definitive airway management.

[Haematoma of the floor of the mouth associated to acute myocardial infarction]

We report the case of an 80-year-old man who developed a haematoma in the floor of the mouth after receiving alteplase in the treatment of an acute myocardial infarction. Both the treatment received and appropriate preventive measures to avoid such haematomas are described.

Lingual Hematoma and Heparin-induced Thrombocytopenia: A Case Report

Lingual hematoma is a rare but potentially fatal cause of upper airway obstruction. Patients receiving anticoagulants such as heparin can suffer from significant complications of these medications. Not only does heparin exert effects directly on the coagulation cascade, but it has the potential to cause thrombocytopenia by stimulating formation of antibodies against platelets. We present the case of a patient being treated with heparin for a deep-vein thrombosis, who subsequently developed heparin-induced thrombocytopenia and lingual hematoma, necessitating tracheotomy.

Lingual hematoma threatening airway obstruction in a patient on oral anticoagulation with warfarin

Warfarin sodium is a commonly used oral anticoagulant agent. It has been well documented that, when effective anticoagulant therapy is employed in treating thromboembolic disease, hemorrhage is a possible complication that can be spontaneous without a history of trauma. The numerous sites of bleeding are the genitourinary and gastrointestinal tracts, the central nervous system, the nose (epistaxis), the penis (priapism), the retroperitoneum, wounds (surgical or traumatic), and subcutaneous tissues during warfarin therapy, but the hemorrhage rarely causes bleeding compromising a patient's airway. We report a case of a spontaneous lingual hematoma that developed during oral anticoagulation therapy. This life-threatening complication of warfarin therapy and its successful management without surgery indicates that observation, close monitoring and reversal of anticoagulation can be a reasonable management option.

Case of the month: A case of airway obstruction following tenecteplase administration

The value of thrombolysis in the treatment of acute myocardial infarction is well established. Haemorrhage into subcutaneous tissues is fortunately a rare complication of fibrinolytic administration. However, if as a result of trauma a haematoma develops within the neck following thrombolysis, it can lead to rapid airway compromise. This is the first reported case of tenecteplase administration leading to subcutaneous haemorrhage and consequent airway compromise. It is also the first reported case where the antecedent trauma was a jaw thrust.

Life-threatening orolingual angioedema during thrombolysis in acute ischemic stroke

BACKGROUND

Orolingual angioedema can occur during thrombolysis with alteplase in stroke patients. However, data about its frequency, severity and the significance of concurrent use of angiotensin-converting-enzyme inhibitors (ACEi) are sparse.

OBJECTIVE

(1), to alert to the potentially life-threatening complication of orolingual angioedema. (2), to present CT-scans of the tongue which exclude lingual hematoma. (3), to estimate the frequency of orolingual angioedema. (4), to evaluate the risk associated with the concurrent use of ACEi.

METHODS

Single center, databank-based observational study on 120 consecutive patients with i. v. alteplase for acute stroke. Meta-analysis of all stroke studies on alteplase-associated angioedema, which provided detailed information about the use of ACE-inhibitors. Across studies, the Peto odds ratio of orolingual angioedema for "concurrent use of ACEi" was calculated.

RESULTS

Orolingual angioedema occurred in 2 of 120 patients (1.7%, 95% CI 0.2-5.9 %). Angioedema was mild in one, but rapidly progressive in another patient. Impending asphyxia prompted immediate intubation. CT showed orolingual swelling but no bleeding. One of 19 (5%) patients taking ACEi had orolingual angioedema, compared to 1 of 101 (1%) patients without ACEi. Medline search identified one further study about the occurrence of alteplase-associated angioedema in stroke patients stratified to the use of ACEi. Peto odds ratio of 37 (95 % CI 8-171) indicated an increased risk of alteplasetriggered angioedema for patients with ACEi (p <0.001).

CONCLUSION

Orolingual angioedema is a potentially life-threatening complication of alteplase treatment in stroke patients, especially in those with ACEi. Orolingual hematoma as differential diagnosis can be excluded by CT-scan.

Critical Hemorrhage in the Floor of the Mouth During Implant Placement in the First Mandibular Premolar Position: A Case Report

Although dental implantation is considered to be a safe surgical procedure, this report focuses on a critical hemorrhaging episode associated with implant placement in the first mandibular premolar position. Excessive bleeding and formation of massive lingual, sublingual, and submandibular hematomas were the result of arterial trauma that occurred during the osteotomy preparation. The vascular injury was induced through a perforation of the lingual mandibular cortex. Critical bleeding was conservatively controlled and the case was further handled efficiently with an expectant airway management in a hospital environment. Similar case reports are reviewed in an attempt to draw attention to this rare but potentially life-endangering risk of implant dentistry. Common causes of severe hemorrhage in the floor of the mouth, anatomical considerations, bleeding control measures, and related airway issues are also discussed.
