Project description:IntroductionThoracic endovascular aortic repair (TEVAR) is a useful treatment for acute type B aortic dissection (TBAD). A PETTICOAT (Provisional ExTension to Induce COmplete ATtachment) procedure can be an alternative surgical option for a patent false lumen. Non-obstructive aortic angioscopy is an attractive modality that can visualize the aortic intima for things such as entry or re-entry tears that are difficult to detect with computed tomography (CT). Herein, we describe a successful PETTICOAT procedure assisted by aortic angioscopy for subacute TBAD complicated by lower limb ischemia.Presentation of caseA 63-year-old man who had been treated with conservative therapy for subacute TBAD had intermittent claudication. Enhanced CT revealed a primary entry tear at the distal arch, and the true lumen at the thoracoabdominal level was narrowed by the patent false lumen. Therefore, the PETTICOAT procedure was performed. The postoperative course was uneventful, with normalized lower limb pressure.DiscussionAlthough PETTICOAT procedure is effective for treating complicated TBAD, there is no consensus on where and how far the proximal stent graft or distal bare stent should be implanted. Non-obstructive aortic angioscopy during PETTICOAT is useful to detect and cover the entry and re-entry tears. The PETTICOAT procedure assisted by aortic angioscopy could contribute to determining the appropriate coverage range of the stent graft.ConclusionAortic angioscopy could contribute to the surgical success of PETTICOAT procedure for complicated subacute TBAD.

Project description:RationaleAcute type A aortic dissection (AAAD) is a potentially fatal clinical crisis. Hemorrhagic cardiac tamponade due to the rupture of an ascending aortic root dissection is extremely dangerous and often lacks timely clinical evidence. We report sudden death in a patient diagnosed with AAAD and in whom critical care ultrasound highly indicated hemorrhagic cardiac tamponade.Presenting concernsA 75-year-old man was admitted to our emergency department with a complaint of chest pain for 8 hours. Computed tomography angiography findings indicated AAAD with a wide range of lesions. During the preoperative preparation process, he suddenly lost consciousness with a pulseless femoral artery.Diagnoses: Cardiopulmonary resuscitation was initiated and critical care ultrasound revealed hemorrhagic cardiac tamponade, strongly indicating the rupture of an ascending aortic root dissection.InterventionsHowever, family members refused further surgical interventions.OutcomesThe etiology could not be reversed and the patient died.LessonsCritical care ultrasound is an important skill that intensivists should master for fast screening of life-threatening complications in patients with AAAD.

Project description:Although uncommon, acute aortic dissections are a life-threatening, cannot miss diagnosis for the emergency medicine clinician. Point of care ultrasound can play an integral role in the initial work up of the undifferentiated patient. While not initially utilized to make the diagnosis of aortic dissection, the ultrasound images obtained in this case describe key findings on ultrasound vital for an emergency clinician to recognize. It is essential for emergency medicine clinicians to differentiate an aortic dissection from other causes of chest pain and abdominal pain because the quick mobilization of resources plays a key role in the management and outcome of such patients.TopicsAortic dissection, vascular, dissection flap, back pain, point of care ultrasound, POCUS.

Project description:BackgroundThe occurrence of type A aortic dissection (TAAD) during transoesophageal echocardiography (TEE) has only been reported once. We present another case of pre-procedural type B AD with retrograde TAAD or de novo TAAD during the TEE procedure.Case summaryAn 81-year-old man with a pre-existing infrarenal abdominal aortic aneurysm and highly tortuous aorta was referred to our ward for acute decompensated heart failure (ADHF) with New York Heart Association functional class II. On hospital Day 2, the patient complained of intermittent dull pain over chest and back; ADHF or acute coronary syndrome was suspected. On Day 3, we transferred the patient to the intensive care unit due to ADHF with cardiogenic shock attributed to fluid overload, atrial fibrillation with rapid ventricular response, and severe mitral regurgitation with severely impaired left ventricular ejection fraction. Given the heightened surgical risk, TEE was performed to evaluate the eligibility of mitral transcatheter edge-to-edge repair. The first mid-oesophageal long-axis view showed no evidence of dissection. After 20 min, the same view showed the occurrence of TAAD. Urgent contrast CT confirmed a TAAD extending from the aortic root to the infrarenal abdominal aorta. Due to the prohibitive risk for surgical repair of TAAD, the patient received palliative care and unfortunately passed away on hospital Day 6.DiscussionAlbeit rare, TAAD could progress or de novo occur during TEE, especially in high-risk patients. Therefore, high alertness during TEE procedures is imperative. Moreover, in patients with AD and poor renal function, the risk of using TEE as an alternative diagnostic modality should be carefully considered.

Project description:BackgroundThoracic endovascular aortic repair (TEVAR) is the therapeutic choice for type B aortic dissection. One of the most unfavored complications of this procedure is hemorrhage, which has a low incidence but high mortality. Renal hemorrhage (RH) after endovascular aortic repair has been rarely reported. We presented two cases of unexpected RH after TEVAR for complicated type B aortic dissection, and the potential causes, diagnosis and therapeutic management were discussed.Case presentationA 67-year-old female developed hypotension and progressively decrease of hemoglobin within 5 h after TEVAR for acute complicated type B dissection. Bedside ultrasonography and abdominal computed tomography angiography revealed a massive right perinephric hematoma. The right renal angiography detected multiple tortuous vascular branches with diffuse perinephric bleeding. The main trunk of right renal artery was embolized. The patient recovered uneventfully and presented with normal renal function 6 months later. Another patient was a 69-year-old male who was admitted for endovascular repair of a chronic complicated type B aortic dissection. The patient presented with hemodynamic instability early after TEVAR. Bedside ultrasonography showed a giant left retroperitoneal hematoma. The abdominal angiography revealed two active bleeding sits located in the distal branches of left renal artery. A super-selective embolization of the two arteries was performed, however the patient developed abdominal compartment syndrome and died of multiple organ failure.ConclusionsUnexpected RH after endovascular repair of aortic dissection might be associated with iatrogenic and idiopathic factors. Close surveillance and clinician's awareness of this rare complication is crucial for accurate and prompt diagnosis. Renal angiography and subsequent selective embolization of bleeding vessels are effective interventions for treating this fatal condition.

Project description:RationalePheochromocytoma crises are very rarely seen in children. In this report, we present a case of the death related to occult pheochromocytoma crisis combined cerebral infarction.Patient concernsA 5-year-old boy has a 1-month history of polydipsia, polyuria, sweating, and weight loss of 2.5 kg. He was admitted to our hospital because of 1 week of anorexia, 2 days of vomiting, and 12 hours of convulsions and confusion. Magnetic resonance imaging of the brain and cervical spinal cord showed abnormal signals in the left parie-occipital lobe, medulla oblongata till C7 cervical vertebrae.DiagnosesBased on patient's complaints and clinical appearance, provisional diagnosis of pheochromocytoma crisis complicated brainstem infarction was considered.InterventionsTracheal intubation, volume expansion, continuous infusion of dobutamine, and sedation reduce intracranial pressure. Chest compression was performed when the child suddenly developed sobbing respiration.OutcomesThe patient was dead. Congenital metabolic defects screening suggested mild ketonuria. Trio whole exon sequencing revealed a synonymous mutation of von Hippel-Lindau syndrome c.414 A > G in the decedent. Autopsy revealed pheochromocytoma, acute myocarditis, liquefaction necrosis of the medulla oblongata cerebral edema, and congestion.LessonsEarly clinical symptoms of pheochromocytoma in children are not typical. It may induce serious complications and develop into a pheochromocytoma crisis and cause death without proper treatment.

Project description:BackgroundAortic wrapping (AW) has been performed as a less invasive alternative to aortoplasty. However, AW can also cause long-term aortic complications. In this report, we present a rare case of a dissecting aortic aneurysm between the proximal side of the wrap and the sinotubular junction after AW.Case presentationA female patient had undergone urgent aortic valve replacement with a 19-mm mechanical valve to treat infective endocarditis and AW to treat an enlarged ascending aorta 26 years prior. At the age of 71 years, the patient was diagnosed with a dissecting aortic aneurysm between the proximal side of the wrap and the sinotubular junction. We performed graft replacement of the ascending aorta, including complete resection of the wrap. The patient was discharged on postoperative day 10, and there have been no cardiovascular events during her ongoing follow up.ConclusionsAW in younger patients can lead to late aortic complications. Careful consideration should be paid when performing AW in young patients, and patients who have previously undergone AW require strict life-long follow-up.

Project description:BackgroundDe Winter electrocardiograph (ECG) pattern is an atypical presentation of acute myocardial infarction (AMI) due to severe stenosis of the left anterior descending (LAD). Complications of acute aortic dissection (AD) in the setting of acute myocardial infarction (AMI) with de Winter sign are relatively rare and physicians may easily miss the diagnosis of AD. We report a case of patient with acute chest pain and de Winter ECG pattern due to AD involving the left main coronary artery (LM), LAD and left circumflex artery (LCX).Case presentationA 57-year-old male patient was initially diagnosed with AMI and then the diagnosis of acute AD was supported by transthoracic echocardiograph (TTE). After two stents were implanted respectively into the proximal LM-LAD and LM-LCX, he recovered from cardiogenic shock. Two months later, the patient underwent the surgery of ascending aorta replacement. After the surgery, there was no obvious chest discomfort during follow-up.ConclusionsWhen an ECG shows a "de Winter pattern", we should also consider the possibility of AD which result in LAD occlusion. TTE is a useful tool in screening for AD. Further research is needed to prove that percutaneous coronary intervention (PCI) may be a useful treatment strategy in the case of AD leading to severe LAD occlusion and unstable hemodynamics when there's no condition to perform aortic replacement surgery immediately.

Project description:BackgroundThe role of thoracic endovascular aortic repair (TEVAR) has evolved and is now firmly established as a mainstay of therapy for acute complicated type B aortic dissection (acTBAD). However, several important issues remain unresolved including the optimal timing, sizing, graft selection, coverage length and utilization of adjunctive therapies to address false lumen perfusion. Therefore, the purpose of this study was to provide a contemporary perspective on the management and results for TEVAR of acTBAD.MethodsAll TEVAR patients (N.=159) with acTBAD from a single high-volume, academic medical center were analyzed. Comparative results across time-dependent cohorts (2005-2009 [N.=43] vs. 2010-2014 [N.=56] vs. 2015-2020 [N.=60]) are presented.Results30-day mortality was 13%(N.=21) with a trend towards improvement over time (2005-2009, 18% vs. 2010-2020, 12%; P=0.1). Similarly, incidence of postoperative complications also declined: 2005-2009, 70% vs. 2010-2020, 36%(P-trend=0.08). One and 2-year freedom from aorta-related reintervention was 78±7% and 73±9% and did not differ across cohorts (log-rank P=0.5). Respective one and 5-year survival was 75±3% and 64±7%, but significantly improved with time (log-rank P<0.001). The corresponding one and five-year freedom from aorta-related mortality was 82±4% and 78±7% but did not change during the study interval (log-rank P=0.3).ConclusionsOutcomes for TEVAR of acTBAD continue to improve over time. This time-dependent analysis delineates how results have changed due to increasing experience, technologic evolution, and maturation of the peer reviewed evidence. These results along with the evidence-based review provided herein, provide an update on the management and results of TEVAR of acTBAD while highlighting specific controversies unique to the management of this challenging clinical problem.
