[A case of Heyde's syndrome in a patient hospitalized for acute myocardial infarction]. / Un caso di sindrome di Heyde in una paziente ricoverata per infarto miocardico acuto.

We here describe the case of an 84-year-old woman with a history of ischemic heart disease, paroxysmal atrial fibrillation, and severe aortic stenosis, admitted to the coronary care unit of our hospital for an ST-elevation myocardial infarction secondary to in-stent thrombosis and treated with primary percutaneous coronary intervention. On admission, the patient was on chronic therapy with apixaban for atrial fibrillation, and reported no history of bleeding. However, the day after the administration of the loading doses of aspirin and clopidogrel, the patient developed multiple episodes of rectal bleeding and melena, requiring blood transfusions. The endoscopic work-up was negative for bleeding lesions in the upper gastrointestinal tract and in the colon, but with a blood leakage from the ileocecal valve, prompting the diagnostic suspicion of an ileal bleeding secondary to angiodysplasia. Considering the well-known link between severe aortic stenosis and ileal angiodysplasia (i.e. Heyde's syndrome), the patient, already in the waiting list for elective transcatheter aortic valve implantation, underwent the procedure during the index hospitalization. The procedure was performed in the absence of complications and the patient was discharged with a personalized antithrombotic therapy. In the following weeks, no further episodes of bleeding were reported.

Did angiodysplasia associated with heyde's syndrome disappear spontaneously?: a case report.

BACKGROUND: Heyde's syndrome can be easily overlooked or misjudged in clinical practice because it shares common clinical manifestations with multiple diseases as well as limited accuracy of several corresponding examinations for diagnosing Heyde's triad. Moreover, aortic valve replacement is often delayed in these patients due to the contradiction between anticoagulation and hemostasis. Herein, we present a rare case of atypical Heyde's syndrome. The patient's severe intermittent gastrointestinal bleeding was not completely cured even through a local enterectomy. In the absence of direct evidence of acquired von Willebrand syndrome (AVWS) or angiodysplasia, her long-standing gastrointestinal bleeding was finally stopped after receiving transcatheter aortic valve implantation (TAVI). CASE PRESENTATION: A 64-year-old female suffered from refractory gastrointestinal bleeding and exertional dyspnoea. A local enterectomy was performed owing to persistent hemorrhage and repeated transfusions; subsequently, histological examination revealed angiodysplasia. Heyde's syndrome was not suspected until 3 years later, at which time the patient started bleeding again and was also found to have severe aortic valve stenosis upon echocardiography. TAVI was consequently performed when the patient was in a relatively stable condition even though the predisposition to bleed, but there was no evidence of angiodysplasia and AVWS during angiography at that time. The patient's above symptoms were significantly relieved after TAVI and followed up for 2 years without any significant ischemic or bleeding events. CONCLUSIONS: The visible characteristics of angiodysplasia or a shortage of HMWM-vWFs should not be indispensable for the clinical diagnosis of Heyde's syndrome. Enterectomy could be a bridging therapy for aortic valve replacement in patients with severe hemorrhage, and TAVI may be beneficial for moderate to high surgical-risk patients even if they have a potential risk of bleeding.

Heyde Syndrome: An Unusual Cause of Gastrointestinal Bleeding.

Heyde syndrome is a multisystem disorder characterized by the classical triad of aortic stenosis, gastrointestinal (GI) angiodysplasias, and acquired von Willebrand syndrome. GI angiodysplasias, common in older patients, are tortuous, thin-walled blood vessels seen in the mucosa or submucosa of the GI tract and are highly prone to rupture resulting in GI bleeds. In this case report, we describe an elderly female with a past medical history of end-stage renal disease and chronic anemia who presented to the emergency department (ED) with complaints of dark-tarry stools and associated abdominal cramping. Patient reported a history of dark-tarry stools and multiple blood transfusions in the past, secondary to severe anemia. An inpatient echocardiogram was performed, revealing severe aortic stenosis. Additionally, gastroenterology was consulted for esophagogastroduodenoscopy and colonoscopy, which were negative for active bleeding. About a year ago, the patient underwent capsule endoscopy at an outlying facility, which was positive for angiodysplasia. Therefore, due to high clinical suspicion, presence of aortic stenosis, and GI angiodysplasia, a platelet function assay was ordered. It was found to be abnormal, pointing to the presence of acquired von Willebrand syndrome. Hence, a diagnosis of Heyde syndrome was established. The patient gradually improved and was discharged with a follow-up appointment with the cardiologist for a possible transcatheter aortic valve replacement procedure. The patient underwent the procedure without complications, after which she did not report episodes of GI bleeding. In this case report, we discuss the presentation, pathophysiology, diagnostic approach, and management of patients with Heyde syndrome.

Aortic Valve Replacement for Patients with Heyde Syndrome: A Literature Review.

Objective To explore the characteristics and clinical outcomes of patients with Heyde syndrome (HS) who undergo aortic valve replacement (AVR). Methods Electronic databases including PubMed, Embase, Ovid, WANFANG, VIP and CNKI were searched to identify all case reports of HS patients undergoing AVR surgery, using different combinations of search terms "Heyde syndrome", "gastrointestinal bleeding", "aortic stenosis", and "surgery". Three authors independently extracted the clinical data including the patients' characteristics, aortic stenosis severity, gastrointestinal bleeding sites, surgical treatments and prognosis. Results Finally, 46 case reports with 55 patients aging from 46 to 87 years, were determined eligible and included. Of them, 1 patient had mild aortic stenosis, 1 had moderate aortic stenosis, 42 had severe aortic stenosis, and 11 were not mentioned. Gastrointestinal bleeding was detected in colon (n=8), jejunum (n=6), ileum (n=4), cecum (n=3), duodenal (n=3) and multiple sites (n=8). No specific bleeding site was identified in 23 patients. Preoperative hemoglobin level ranged from 43 to 117 g/L. All but one of 16 patients showed decreased level of high molecule weight von Willebrand factor. Of the 55 patients, 43 underwent AVR, and 12 received transcatheter AVR. Aortic valves of 14 cases were replaced by mechanical valves, and 33 cases by biological valves. All patients recovered well during the follow-up, except 5 patients. One patient who had perivalvular leakage and gastrointestinal bleeding after AVR underwent the second AVR. Two patients had recurrent gastrointestinal bleeding. Two patients died of life-threatening acute subdural hematoma and multiple organ failure, respectively. Conclusions HS is a rare syndrome characterized by aortic stenosis and gastrointestinal bleeding. AVR is an effective treatment for HS.

Successful laparoscopic surgery combined with selective arterial embolization for bleeding due to jejunal angiodysplasia: a case report.

BACKGROUND: Angiodysplasia of the gastrointestinal tract is a rare vascular pathology that sometimes causes massive hemorrhage. Angiodysplasias are particularly difficult to find in the small intestine for anatomical reasons, often impeding their diagnosis and treatment. Lesion localization is a major challenge in cases of small bowel bleeding requiring surgical intervention. CASE PRESENTATION: The present case was a 52-year-old woman who was urgently hospitalized with repeated tarry stools. Surgical intervention was chosen after conservative treatment failed to improve her condition. The source of bleeding was suspected to be a vascular lesion discovered in the small intestine during a past double-balloon endoscopy. Abdominal contrast computed tomography revealed a jejunal hemorrhage. We chose selective arterial embolization to stabilize her hemodynamics followed by surgical intervention as her treatment plan. Several embolic and contrast agents (cyanoacrylate, indigo carmine, and Lipiodol) were combined to help identify the location of the lesion during surgery. This multi-pronged approach allowed us to localize the lesion under laparoscopic guidance with high confidence and accuracy, and to excise a 6-cm segment of the small intestine. The lesion was histologically diagnosed as angiodysplasia. No re-bleeding has been observed since the operation. CONCLUSION: We report our experience with a case of jejunal angiodysplasia, which was localized with selective arterial embolization using an array of embolic and contrast agents, and then excised laparoscopically. Selective arterial embolization with indigo carmine dye to treat small bowel bleeding preoperatively not only makes the surgery safer by stabilizing the patient's hemodynamics, but is also very useful for localizing the lesion intraoperatively.

Of aortic valve and bleeding: Heyde's syndrome.

An 80-year-old woman with severe aortic stenosis presented with relapsing enterorrhagia and severe anemia. A video capsule pan-endoscopy showed multiple sites of complex mucosal angiodysplasia in the jejunum. Direct hemostatic treatment of accessible angiodysplasia was done with argon plasma coagulation, and the patient was urgently referred for trans-catheter aortic valve replacement (TAVR). At follow-up 1 month and 3 months later, she was doing well with no further episodes of bleeding. Heyde's syndrome is referred to as the association of aortic stenosis, gastrointestinal angiodysplasia, bleeding, and anemia. It is an acquired type2A von Willebrand syndrome caused by the proteolysis and loss of the largest polymers of vWF due to the high shear forces generated through the stenotic aortic valve. The qualitative and quantitative vWF defects play a central role in the angiogenesis and development of gastrointestinal angiodysplasia The vWF abnormalities are closely associated with the hemodynamic severity of the aortic valve stenosis. Valve replacement is the pivotal strategy to achieve the long-term resolution of bleeding recurrences. TAVR is a valuable option particularly in high-risk patients for whom surgical valve replacement is not feasible.

[Heyde syndrome successfully treated with transcatheter aortic valve implantation to prevent recurrence of gastrointestinal bleeding from angiodysplasia].

While hospitalized due to severe aortic stenosis, an 84-year-old woman developed repeated bleeding from angiodysplasia in the stomach leading to a diagnosis of Heyde syndrome. Following transcatheter aortic valve implantation (TAVI), there was no recurrence of bleeding from the angiodysplasia, and the decrease in von Willebrand factor levels that caused Heyde syndrome also improved. It was felt that the TAVI was able to prevent the recurrence of gastrointestinal bleeding due to angiodysplasia in Heyde syndrome.

[Jejunal phlebectasia as a cause of massive gastrointestinal haemorrhage]. / Flebectasia yeyunal como causa de hemorragia digestiva media masiva.

Vascular abnormalities of the gastrointestinal tract are a common cause of gastrointestinal bleeding. Most of them are located within the reach of the upper endoscopy or colonoscopy, although once discarded, it forces to consider small bowel as the source of bleeding. The successful management of a gastrointestinal bleeding depends mainly on the timely location of the source of bleeding. Nevertheless this task can be difficult when the cause is not within the reach of conventional methods. We present a case of a 21 year-old men in which the diagnosis of bleeding yeyunal phlebectasia was made by the findings of the capsule endoscopy and laparoscopy.

Flebectasia yeyunal como causa de hemorragia digestiva media masiva / Jejunal phlebectasia as a cause of massive gastrointestinal hemorrhage

Las anormalidades vasculares del tracto gastrointestinal son una causa común de sangrado digestivo. La mayoría se localizan al alcance de la endoscopía digestiva alta y/o colonoscopía, una vez descartado ello, obliga a considerar al intestino delgado como causa de la hemorragia. El manejo exitoso de una hemorragia digestiva depende principalmente de la localización oportuna de la fuente del sangrado, sin embargo esta tarea puede ser difícil, cuando la causa no está al alcance de los métodos convencionales. Presentamos el caso de un paciente varón de 21 años cuyo diagnóstico fue una flebectasia yeyunal sangrante, luego de una cuidadosa evaluación de los hallazgos de la cápsula endoscópica y laparoscopía.

[Surgical treatment of patients with arteriovenous head and neck angiodisplasia]. / Khirurgicheskoe lechenie bol'nykh s arteriovenoznymi angiodisplaziiami v oblasti golovy i shei.

The aim of the study was to assess the results of surgical treatment in 74 patients with extensive arteriovenous angiodisplasia in the head and neck area. All patients underwent complex examination including ultrasound, CT and MRI with contrast and selective carotid angiography. The lesions excision was performed after endovascular embolization and soft tissue defects were restored by various methods selected according to prevalent vascular lesion type (arterial, arteriovenous, venous, capillary) and blood flow values (high flow, low flow, mixed). Good and satisfactory esthetic results were seen in 95.2% of cases, lesion relapse was detected in 4.8% of cases by 12-18 months follow-up. Endovascular embolization proved to decrease the intraoperative bleeding risk, prevent lesion relapse and minimize the size of the lesion improving the results of radical treatment. Local flap reconstruction usually results in good esthetic results. By local soft tissue deficiency distant free flaps or microsurgical complex flaps may be used.

Perioperative approach of patient with takotsubo syndrome / Abordagem perioperatória de doente com síndrome de takotsubo

Abstract Introduction: Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy. It is characterized by an acute onset of symptoms and electrocardiographic abnormalities mimicking an acute coronary syndrome in the absence of obstructive coronary artery disease. Any anesthetic-surgical event corresponds to a stressful situation, so the anesthetic management of patients with TCM requires special care throughout the perioperative period. We describe the anesthetic management of a patient with a confirmed diagnosis of TCM undergoing segmental colectomy. Case report: Female patient, 55 years old, ASA III, with history of takotsubo syndrome diagnosed 2 years ago, scheduled for segmental colectomy. The patient, without other changes in preoperative evaluation, underwent general anesthesia associated with lumbar epidural and remained hemodynamically stable during the 2 h of surgery. After a brief stay in the Post-Anesthesia Care Unit, she was transferred to the Intermediate Care Unit (IMCU), with epidural analgesia for postoperative period. Conclusion: TCM is a rare disease which true pathophysiology remains unclear, as well as the most appropriate anesthetic-surgical strategy. In this case, through a preventive approach, with close monitoring and the lowest possible stimulus, all the perioperative period was uneventful. Because it is a rare disease, this report could help to raise awareness about TCM.

Resumo Introdução: A miocardiopatia takotsubo (MT) é uma miocardiopatia induzida pelo estresse. Caracteriza-se por um início agudo de sintomas e alterações eletrocardiográficas que mimetizam uma síndrome coronária aguda na ausência de doença arterial coronária obstrutiva. Qualquer evento anestésico-cirúrgico corresponde a uma situação de estresse, pelo que a abordagem anestésica dos doentes com MT exige um cuidado especial em todo o período perioperatório. Descrevemos a abordagem anestésica de uma doente com diagnóstico confirmado de MT submetida a colectomia segmentar. Caso clínico: Paciente do sexo feminino, 55 anos, ASA III, com antecedentes de síndrome de takotsubo diagnosticada havia dois anos, encaminhada para colectomia segmentar. A paciente, sem outras alterações na avaliação pré-operatória, foi submetida a anestesia geral associada a epidural lombar e manteve-se hemodinamicamente estável durante as duas horas do procedimento cirúrgico. Após uma breve permanência na Unidade de Cuidados Pós-Anestésicos foi transferida para a Unidade de Cuidados Intermédios (UCIM) com analgesia peridural para o pós-operatório. Conclusão: A MT é uma doença rara, cuja verdadeira fisiopatologia continua por esclarecer, assim como a estratégia anestésico-cirúrgica mais apropriada. Nesse caso, por causa de uma abordagem preventiva, com monitoração rigorosa e o menor estímulo possível, todo o perioperatório decorreu sem intercorrências. Sendo uma doença rara, o seu relato poderá contribuir para o avanço do conhecimento sobre a MT.
