Temporomandibular joint (TMJ) surgeries cover a vast assortment of surgical procedures such as tooth extractions, tissue biopsies, and extensive maxillofacial surgeries. Major complications that occur during and after TMJ surgeries include uncontrolled bleeding, considerable blood loss, serious infections, and edema. Tranexamic acid (TXA) is an antifibrinolytic agent that reduces blood loss by inhibiting the enzymatic breakdown of fibrin. Currently, TXA is widely used in various orthopedic surgeries to reduce bleeding and decrease the need for blood transfusions. In this study, we observed five patients undergoing major TMJ replacement surgeries and administered TXA during the procedure. The principal aim of this study was to examine the association between TXA administration during TMJ replacement surgery and blood loss and tissue edema.
Congestive heart failure has long been a well-known cause of both morbidity and mortality for thousands of people worldwide. Consequences of decompensated heart failure are systemic and widespread, including but not limited to pulmonary edema, dyspnea, hypoxia, peripheral edema, and end-organ hypoperfusion. Common etiologies of congestive heart failure include systemic hypertension, coronary artery disease, longstanding alcohol abuse, valvular dysfunctions, and myocarditis. While the vast majority of congestive heart failure cases are secondary to one of these common etiologies, there is a subset of cases that cannot be traced to any of these causes and are most often grouped under the category of idiopathic. One rarely seen etiology of decompensated heart failure is an arteriovenous fistula, whether naturally occurring or iatrogenic. We report a case of an iatrogenic AV fistula secondary to percutaneous coronary intervention causing severe decompensated heart failure that was successfully treated with surgical ligation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
