SummaryBackground:Acute type A aortic dissection (AAAD) is a cardiovascular emergency with a high potential for death. Rapid surgical treatment is indicated to prevent fatal complications. Aggressive appropriate medical management starts at first suspicion and is essential to prevent exacerbation or rupture of the dissection. Despite improved surgical techniques, perioperative care and the development of specialized cardiovascular centers, mortality remains high. Organ ischemia is a catastrophic manifestation of aortic dissection, demanding acute surgical intervention in specialized cardiovascular centers.Case Report:We present the case of a 62-year-old man with isolated acute limb ischemia due to an acute type A aortic dissection treated in a regional general hospital, without a specialized cardiovascular service, with immediate open malperfusion repair and aggressive medical management. The patient did not undergo further surgical aortic repair, and after a 30-month follow-up he remains symptom free and in good clinical condition, suggesting that although aortic surgery remains the gold standard for treatment of acute Type A dissection, appropriate medical management and early malperfusion repair may offer an initial limb- or life-saving procedure.Conclusions:This staged approach gives clinicians more time to properly evaluate and transfer the patient to a specialized cardiovascular center, and in some cases may even offer a definite treatment.
Coronavirus disease is a viral infection that can affect multiple systems and be expressed with many—or no—symptoms. The viral infection begins when the virus binds to the host’s receptor and from that point on, it is transmitted to the rest of the body, where it causes inflammatory reactions. Among other tissues and systems, SARS-CoV-2 impacts the coagulation system, where it triggers the immunothrombotic response. Its effects are rather intense and can lead to many complications. COVID-19-associated coagulopathy is frequently observed in hospitalized patients, especially ICU patients, and can be proven detrimental. It is usually accompanied by other complications, such as sepsis-induced coagulopathy, disseminated intravascular coagulation and venous thromboembolism. Since all these conditions lead to poor prognosis for severely ill patients, thromboprophylaxis and coagulopathy prognosis are just as important as the therapeutic handling of these patients. Since the beginning of the pandemic, many biomarkers have been considered useful when trying to assess the thrombotic risk of hospitalized patients or evaluate the severity of their situation. At the same time, many drugs have already been tested—while others are still being trialed—in order to find the optimal therapy for each urgent situation.
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.
