Project description:Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute myocardial infarction. We examine 4 atypical presentations of SCAD. These cases highlight treatment course and outcomes for patients with SCAD who do not present with acute coronary syndrome.

Project description:Both spontaneous superior mesenteric artery dissection (SMAD) and spontaneous renal artery dissection (SRAD) are very rare conditions. Their etiologies and natural histories are not precisely defined, but they are thought to be associated with underlying conditions. In this report, we describe an extremely rare case of SRAD in a man who had a history of spontaneous SMAD. We successfully treated SRAD with endovascular intervention. Isolated spontaneous SMAD and SRAD are both rare conditions. Their optimal treatment has not been established due to their rare entities, but endovascular treatment is a good option because it can prevent both advancement of infarction and renovascular hypertension, and it has become safer as device technology has improved. Patients with isolated visceral artery dissection should be carefully followed up.

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:Spontaneous renal artery dissection (SRAD) is a rare entity causing muscle spasm due to acute low back pain, back pain, or flank pain symptoms or misleading clinical diagnosis such as renal colic. A 25-year-old Syrian male refugee presented to the emergency department with sudden onset of left-sided flank pain in the evening. Physical examination results were normal except left-sided costovertebral angle sensitivity. Abdominal, pelvic and thoracic contrast computed tomography angiography (CTA) was performed to evaluate aortic dissection, which was our urgent preliminary diagnosis. Left renal artery dissection was detected in CTA. The patient was treated with medical conservative treatment and spontaneous recovery was observed during the follow-up period. Early detection of SRAD in the emergency department can be difficult due to the fact that the clinical presentation is misleading.

Project description:Spontaneous coronary artery dissection in infants is a rare phenomenon. We present 2 neonates with severe ventricular dysfunction due to coronary artery dissection. Neither patient had evidence of extracardiac fibromuscular dysplasia or other comorbidities that would explain the presentation. (Level of Difficulty: Advanced.).

Project description:Spontaneous renal artery dissection is a rare clinical entity, and symptoms vary from non-specific abdominal pain to life-threatening hypertension. A 44-year-old woman with no significant medical history initially presented with symptoms suggestive of urinary tract infection which did not respond to antibiotic therapy. Imaging revealed right renal infarction resulting from focal spontaneous renal artery dissection, which was managed conservatively. CT angiography is the preferred imaging modality for the diagnosis of this condition. Treatment options include medical management of hypertension with or without anticoagulation, endovascular intervention and surgical revascularisation depending on the presentation and the extent of the vascular and renal parenchymal involvement. This case emphasises the need to have high index of suspicion for uncommon diagnoses in patients who present with common symptoms but do not respond to empiric therapy.

Project description:A 38-year-old with Turner syndrome presented with acute myocardial infarction due to multivessel spontaneous coronary artery dissection (SCAD) complicated by left ventricular free wall rupture. Conservative management for SCAD was pursued. She underwent sutureless repair for an oozing-type left ventricular free wall rupture. SCAD has not been previously reported in Turner syndrome.

Project description:Spontaneous coronary artery dissection (SCAD) is a pathophysiologically distinct cause of acute coronary syndromes (ACS). It is increasingly recognized that optimal management is different from that for atherosclerotic ACS and that a SCAD diagnosis has specific long-term prognostic and therapeutic implications. Accurate diagnosis is therefore essential to ensure the best treatment of patients. At present this relies on the recognition of typical features of SCAD identified on invasive coronary angiography. Although most SCAD can be readily distinguished angiographically from alternative causes of ACS, false positive and false negative diagnoses remain common. In particular, sometimes non-SCAD presentations, including atherothrombosis, takotsubo cardiomyopathy, coronary embolism, coronary vasospasm, contrast streaming, and myocardial infarction with nonobstructive coronary arteries, can mimic angiographic features usually associated with SCAD. The authors present the combined experience from European and US SCAD referral centers reviewing the classical angiographic appearances of SCAD, presenting potential diagnostic pitfalls and exemplars of SCAD mimickers. The authors further review the benefits and limitations of intracoronary imaging in the context of SCAD. Finally, the authors discuss the investigation of ambiguous cases and an approach to minimize misdiagnosis in difficult cases.

Project description:IntroductionSCAD involves a sudden tear or separation within the layers of the coronary artery wall, resulting in blood flow obstruction and subsequent myocardial ischemia.Materials and methodsA comprehensive literature search was conducted to identify relevant published cases of cutting balloon use in patients diagnosed with spontaneous coronary artery dissection. Electronic databases including PubMed, MEDLINE, Embase, Cochrane Library and Google Scholar were systematically searched from inception until the present using terms "cutting balloon," "SCAD," "acute coronary syndrome," "intramural hematoma," and "angioplasty."ResultsA total of 32 published cases of cutting balloon use in spontaneous coronary artery dissection were analyzed in this study. The majority of the patients included in the analysis were female without prior history of cardiovascular disease. The median age of the SCAD population was approximately 46 years. The most frequently affected artery in SCAD cases was the Left Anterior Descending artery. Intravascular ultrasound was utilized more frequently than other modalities of adjunctive imaging techniques. The most frequent complication was the distal propagation of hematoma. Despite the successful dilation achieved with the cutting balloon, in some cases stenting was required to provide additional support.ConclusionThe results of this analysis demonstrate that cutting balloon use in SCAD cases yields favorable outcomes.
