Spontaneous dissection of internal carotid artery masquerading as angioedema.

ABSTRACT: Spontaneous dissection of the internal carotid artery usually presents with stroke-like symptoms secondary to ischemia in its vascular territory, as well as local signs and symptoms, which may include head, face or neck pain, Horner's syndrome, pulsatile tinnitus, and cranial nerve palsies. We report a case of a 44-year-old healthy white male who presented with tongue swelling mimicking angioedema as an unusual manifestation of spontaneous dissection of the internal carotid artery. Two weeks after the initial presentation, the patient returned with similar symptoms and slurred speech. Upon physical examination, he was noted to have isolated left-sided hypoglossal nerve palsy. Subsequent diagnostic imaging revealed segmental narrowing of the left internal carotid artery. The appearance was consistent with the presence of a spontaneous internal carotid artery dissection with associated pseudoaneurysm formation.

Spontaneous renal artery dissection masquerading as urinary tract infection.

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.

Spontaneous coronary artery dissection masquerading as Takotsubo cardiomyopathy: a case report.

Project description:BackgroundAlthough obstructive coronary artery disease (CAD) is the most likely cause of acute coronary syndromes (ACS), nearly one in 20 individuals with clinical myocardial infarction (MI) do not have obstructive CAD. For many such individuals, presentation of Takotsubo cardiomyopathy frequently mimics presentation of MI, though spontaneous coronary artery dissection (SCAD) is an increasingly recognized aetiology of MI in women.Case summaryThis case report describes a woman with chest pain, found to have non-obstructive CAD on angiogram and left ventricular apical dysfunction on echocardiogram raising suspicion for Takotsubo cardiomyopathy. Additional suspicion for SCAD led to coronary CT angiogram (CCTA) which ultimately confirmed this diagnosis.DiscussionFamiliarity with a differential diagnosis for non-obstructive CAD is less common than that for obstructive coronary disease. This case emphasizes the clinical features that should raise suspicion for SCAD when Takotsubo is presumed and outlines the clinical utility of CCTA in making this diagnosis when angiography is unrevealing.

Emergent surgical embolectomy in conjunction with cervical internal carotid ligation and superficial temporal artery-middle cerebral artery bypass to treat acute tandem internal carotid and middle cerebral artery occlusion due to cervical internal carotid artery dissection.

Project description:BackgroundAcute tandem cervical dissecting internal carotid artery (ICA) occlusion and intracranial embolic middle cerebral artery (MCA) occlusion can be devastating, and the optimal treatment strategy for this condition has not been established yet.Case descriptionA 45-year-old male presented with aphasia and right hemiparesis preceded by neck pain. Computed tomography showed a high-density signal along the left MCA, suggesting extensive emboli. Magnetic resonance angiography demonstrated tandem occlusion of the left cervical ICA and intracranial MCA with minimal diffusion-weighted imaging lesion. Emergent surgical embolectomy was performed, and long intracranial MCA emboli were retrieved with collateral cross-flow restoration. The cervical ICA was exposed, and dissection was confirmed. The cervical ICA was ligated, and superficial temporal artery (STA)-MCA anastomosis was added. Postoperatively, the patient demonstrated recovery from right hemiparesis and aphasia. At the 6(th) postoperative month, follow-up studies demonstrated a robustly patent STA-MCA bypass and no additional ischemic lesion on T2-weighted imaging.ConclusionsSurgical embolectomy in conjunction with ligation of the cervical ICA followed by STA-MCA bypass might be a safe alternative method to endovascular recanalization, when the cervical dissection is extensive and when huge secondary emboli are present along the MCA.

Clopidogrel-Associated Thrombotic Thrombocytopenic Purpura following Endovascular Treatment of Spontaneous Carotid Artery Dissection.

Project description:Thrombotic thrombocytopenic purpura (TTP) is a life-threatening multisystem disease secondary to platelet aggregation. We present a patient who developed profound thrombocytopenia and anemia 8 days following initiation of therapy with clopidogrel after stent placement for carotid artery dissection. She did not have a disintegrin and metalloproteinase with thrombospondin domain 13 (ADAMTS 13) deficiency. Management included steroids and therapeutic plasma exchange. Clopidogrel has rarely been associated with TTP. Unlike other causes of acquired TTP, the diagnosis of early clopidogrel-associated TTP is largely clinical given the infrequent reduction in ADAMTS 13 activity.

Spontaneous Renal Artery Dissection in a Man with Previous Spontaneous Superior Mesenteric Artery Dissection.

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.

Isolated hypoglossal nerve palsy from internal carotid artery dissection related to PKD-1 gene mutation.

Project description:BACKGROUND:Internal carotid artery dissection has been well recognized as a major cause of ischaemic stroke in young and middle-aged adults. However, internal carotid artery dissection induced hypoglossal nerve palsy has been seldom reported and may be difficult to diagnose in time for treatment; even angiography sometimes misses potential dissection, especially when obvious lumen geometry changing is absent. CASE PRESENTATION:We report a 42-year-old man who presented with isolated hypoglossal nerve palsy. High-resolution MRI showed the aetiological dissected internal carotid artery. In addition, a potential genetic structural defect of the arterial wall was suggested due to an exon region mutation in the polycystic-kidney-disease type 1 gene. CONCLUSIONS:Hypoglossal nerve palsy is a rare manifestations of carotid dissection. High-resolution MRI may provide useful information about the vascular wall to assist in the diagnosis of dissection. High-throughput sequencing might be useful to identify potential cerebrovascular-related gene mutation, especially in young individuals with an undetermined aetiology.

Project description:Background:The development of carotid-cavernous fistulas (CCFs) during surgical recanalization of chronic internal carotid artery occlusion (ICAO) may be secondary to severe ICA dissection rather than a focal tear of the cavernous ICA seen in typical traumatic CCFs. The purpose of this study is to investigate the causal relationship between the CCFs and severe ICA dissections and to characterize technical outcomes after treatment with stenting. Methods:Five patients underwent treatment with self-expanding stents due to intraprocedural CCF and ICA dissection following surgical removal of ICAO plaque. The stents were telescopically placed via true channel of the dissection. Safety of the procedure was evaluated with 30-day stroke and death rate. Procedural success was determined by the efficacy of CCF obliteration and ICAO recanalization with angiography. Results:All CCFs were associated with spiral and long segmental dissection from the cervical to cavernous ICA. After stenting, successful dissection reconstruction with TICI 3 was achieved in all patients, with complete (n = 4) or partial CCF (n = 1) obliteration. No patient had CCF syndrome, stroke, or death during follow-up of 6 to 37?months; but one patient had pulsatile tinnitus, which resolved 1 year later. Angiography at 6 to 24?months demonstrated CCF obliteration in all 5 patients and durable ICA patency in 4 patients. Conclusions:Intraprocedural CCFs with spiral and cervical-to-cavernous ICA dissection during ICAO surgery are dissection-related because of successful obliteration after stenting for dissection reconstruction. Self-expanding stenting through true channel of the dissection, serving as implanting stent-autograft, may be an optimal therapy for the atypical CCF complication from ICAO surgery.

Aortic dissection or spontaneous renal artery dissection, a rare diagnosis?

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.
