    Full Text Available Spontaneous coronary artery dissection is an extremely rare cause of acute coronary syndrome. Although it predominantly affects young women in the peripartum period, it can also occur in men. The left coronary artery is most frequently involved. The usual presentation is ST segment elevation myocardial infarction. Although several treatment modalities have been proposed, the optimal treatment options still remain to be established. This current case report focuses on a 40- year-old male presented with acute coronary syndrome and subsequently was found to have coronary artery dissection.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction and sudden cardiac death. It occurs most commonly in otherwise healthy women during pregnancy or the postpartum period. The true incidence of SCAD is underestimated, as most cases are diagnosed at autopsy. The pathophysiology of SCAD is still not fully understood, and its management can be challenging. This report describes a 35-year-old pregnant female who presented with an acute antero-lateral ST elevation secondary to spontaneous dissection of the left anterior descending artery and the circumflex artery. The diagnosis was established by coronary artery angiography. However, the patient died following cardiac tamponade. The examination of this case represented a starting point for the reviewing of the diagnosis, clinical course, and management of SCAD, and for the placing of this in context with the existing literature. This study highlights the importance of prompt diagnosis and subsequent lifesaving treatment.

    About 20 cases of cerebrovascular accidents in amusement parks have been documented. However, only a few cases of amusement park stroke (APS) after roller coaster rides have been reported. Here, we present triggers of stroke, clinical characteristics, and the angiographic appearance of 3 consecutive patients of APS. Their clinical characteristics included young age, absence of atherosclerotic risk factors, and severe injuries. Serial changes in angiographic appearance led to the diagnosis of cervicocephalic artery dissection (CAD). Patients A and B were diagnosed with isolated middle cerebral artery (MCA) dissection, and patient C was diagnosed with internal carotid artery dissection involving MCA dissection. Running excitedly toward an attraction in patient A, a go-kart ride in patient B, and riding in an enhanced motion vehicle in patient C were considered as the likely triggers for APS. We had specific cases with APS associated with CAD, which can occur under diverse contexts other than roller coaster rides at amusement parks. Our findings suggest that the variable directions of the high gravitational forces induced by vehicle riding or running excitedly might injure the MCA or internal carotid artery, and thereby cause CAD in the amusement park.

    Full Text Available Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome with a high risk of mortality. The clinical presentation is similar to the atherosclerotic coronary artery disease. The diagnosis is usually made by coronary angiography. Spontaneous coronary artery dissection is more common in women than men. Fast and accurate diagnosis and treatment of spontaneous coronary artery dissection patients improves survival. Therapeutic options include surgery, percutaneous coronary intervention and medical therapy.

    2011-11-01

    A 58-year-old woman visited our hospital with nausea and right flank pain. At first abdominal ultrasonography was performed, suggesting a right renal infarction. Computed tomography (CT) study of the abdomen with intravenous contrast was performed to determine the cause of the symptoms. The scan revealed poor enhancement in the lower half of the right kidney. She was diagnosed with a right renal infarction. She was initially treated with anticoagulant therapy, but 5 days later, she complained of nausea. This time, CT demonstrated exacerbation of a right renal infarction with renal artery dissection. Based on this finding, we performed a right nephrectomy. The result of pathology was segmental arterial mediolysis. She was discharged 12 days after the surgery and is doing well at 6 months after discharge. Spontaneous renal artery dissection is a rare disease. It constitutes approximately 0.05% of arteriographic dissections. In addition, spontaneous renal artery dissection shows nonspecific symptoms. Together, these two factors may cause a delay in diagnosis.

    Full Text Available Abstract A 31 year old man with a 17-year-history of drug abuse (heroine and cannabis was admitted with recurrent chest pain over a period of about three weeks. Chest discomfort severely worsened during the 5 hours before hospital admission. Electrocardiography revealed poor R-wave progression and non specific repolarization abnormalities. Echocardiography showed extensive left ventricular anterior and apical wall motion abnormalities and a ventricular thrombus located at the apex of the left ventricle was present. Subsequently, a diagnosis of acute coronary syndrome was made. Coronary angiography revealed spontaneous coronary artery dissection of the left anterior descending (LAD artery with Thrombolysis In Myocardial Infarction (TIMI flow 2 to 3. We managed the patient conservatively. The clinical course was uneventful and repeated angiography on day 4 demonstrated spontaneous healing of large parts of the dissection with TIMI 3 flow in the LAD.

    Dissecting aneurysms of the middle cerebral artery (MCA) are known to cause cerebral infarcts in younger people and can also cause subarachnoid hemorrhage (SAH) or intracranial hemorrhage. Bleeding caused by an isolated dissecting aneurysm of the MCA is relatively rare. We report the case of a young woman with SAH that occurred subsequent to a ruptured dissecting aneurysm of the MCA which resolved spontaneously as demonstrated by angiography.

    Full Text Available An isolated dissection of the celiac artery is an extremely rare condition that requires a high level of suspicion to evoke the diagnosis. Once established, the natural course is unpredictable in view of the discrepancies in its management requiring a case-by-case analysis. In this paper, we report an unusual case of spontaneous abdominal pain that was diagnosed with celiac and splenic artery rupture secondary to physical stress. This paper underlines the necessity to maintain a high level of suspicion for arterial dissections and we also review the management plan in such cases.

    2012-01-01

    Full Text Available Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome, particularly seen in women during pregnancy or in the puerperium. It has a high acute phase mortality. The etiology is uncertain. Hormonal changes during pregnancy, hemodynamic stress and changes in the autoimmune status have been considered as possible etiological factors. A timely diagnosis and institution of appropriate treatment is important for a successful outcome. There is no consensus of opinion for optimal treatment. Conservative management, coronary artery bypass graft surgery, and percutaneous coronary intervention, all have been described in the literature as possible therapeutic options. Spontaneous coronary artery dissection should be considered as a differential in any young woman presenting with chest pain associated with pregnancy. We report two cases of pregnancy-associated spontaneous coronary artery dissection, both successfully managed, along with a comprehensive review of the previously published literature.

    We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.

    Full Text Available Dyspepsia with mild, stabbing epigastric discomfort without history of trauma is a very common symptom that emergency physicians see in their daily practice. Vascular emergencies, mostly the aortic dissection and aneurysm, are always described in the differential diagnosis with persistent symptoms. Isolated celiac artery dissection occurring spontaneously is a very rare diagnosis. The involvement of branch vessels is generally observed and patients show various clinical signs and symptoms according to the involved branch vessel. Here we are presenting a case with spontaneous isolated celiac artery dissection, without any branch vessel involvement or visceral damage, detected by computed tomography scans taken on admission.

    Full Text Available Abstract Background Spontaneous coronary and vertebral artery dissections are rare events occurring most commonly in otherwise healthy women during pregnancy or the post-partum period. Case presentation This report describes a 35-year-old female who presented with an acute inferior ST elevation myocardial infarction 7 months post-partum secondary to spontaneous dissection of the left obtuse marginal coronary artery. Despite appropriate medical therapy with dual anti-platelet therapy, the patient presented four weeks later with a spontaneous dissection of the right vertebral artery. Conclusion We review the presentation, diagnosis, and management of spontaneous dissections of the vasculature in the peri-partum period.

    Pulmonary artery dissection (PAD) is a rare condition with high mortality and has not been reported in patient with infective endocarditis (IE). Here, we report the first case of such patient who experienced PDA and survived after surgical intervention.A 10-year-old female child was diagnosed as IE with a patent ductus arteriosis (PDA) and a vegetation on the left side of pulmonary artery trunk (10 × 5 mm). Following 3-week antibacterial treatment, the body temperature of patient returned to normal, and the size of vegetation reduced (7 × 3 mm). However, the patient had a sudden attack of sustained and crushing right chest pain, orthopnea with increasing respiratory rate (> 60/min), and acute high fever. Echocardiography revealed the detachment of vegetation on the first day and dissection of pulmonary artery on the next day. The patient received immediate surgical intervention. It was found that aneurysm had a size of 28 × 20 mm and its orifice (the dissecting site) located on the opposite side of the PDA opening (right side of the pulmonary artery trunk). The dissected left wall of pulmonary artery trunk was reconstructed followed by the closure of PDA with suture. The patient recovered uneventfully.From this case, we learned that the surgical intervention should be considered at an early time for IE patients who have a vegetation in pulmonary artery and PDA. After the infection is under control, the earlier surgery may prevent severe complications.

    Once considered uncommon, spontaneous dissection of the carotid artery is an increasingly recognized cause of stroke, headache, cranial nerve palsy, or ophthalmologic events, especially in young adults. Even in the presence of existing signs and symptoms, the diagnosis can be missed by experienced physicians of all specialties. We report a case of spontaneous internal carotid artery dissection in a 38-year-old woman with a cortical stroke and visual disturbances as initial symptoms. The diagnosis was confirmed by magnetic resonance imaging/angiography and by angiography. Prompt anticoagulation was instituted, and the patient had complete resolution of symptoms. Cervicocephalic arterial dissection should be included in the differential diagnosis of the causes of cerebrovascular events.

    Full Text Available Carotid artery dissection is one of the most important causes of cerebral stroke in young age. Although most cases of carotid artery dissection appear spontaneously, sometimes it may result from a microtrauma which the patient does not take seriously. This article reports a case of extracranial internal carotid artery dissection starting from intense swimming and manifesting itself only as neck swelling and neck pain. Other analyses showed that the patient also suffered from a cronic venous sinus thrombosis and stroke. Moreover, genetic testing revealed a MTHFR gene mutation. This case is presented because of the multiple vascular events are seen in the same patient.

    Full Text Available A tortuous common carotid artery poses a high risk of injury during tracheotomy. Preoperative diagnosis is therefore important to avoid serious complications. We found four cases of tortuous common carotid artery during an anatomical dissection course for students. The first case was a 91-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 2 was a 78-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 3 was an 86-year-old woman who died from bladder cancer and who also had a right tortuous common carotid artery without arteriosclerosis. Case 4 was an 89-year-old woman who had bilateral tortuous common carotid arteries and a tortuous brachiocephalic artery with severe arteriosclerosis. Case 4 was also examined using computed tomography to evaluate the arteriosclerosis. Computed tomography revealed severe calcification of the vascular wall, which was confirmed in the aortic arch and origins of its branches. In all four cases, the tortuosity was located below the level of the thyroid gland. Based on prior study results indicating that fusion between the carotid sheath and visceral fascia was often evident at the level of the thyroid gland, we speculated that the major region in which tortuosity occurs is at the same level or inferior to the level of the thyroid gland.

    @@ Dissection of the superior mesenteric artery (SMA) not associated aortic dissection is an uncommon event. The pathogenesis remains unclear. Diagnosis has become more efficient due to recent advances in imaging techniques and increased awareness of mesenteric vessel diseases. Early recognition has led to early interventions. Although there is still no consensus on the best option of management for this disease, an increasing number of patients in recent years have been reported to be treated successfully by non-operative approaches (medical therapy and/or percutaneous endovascular repair) rather than operations. We report the diagnosis and non-operative managements of isolated dissection of SMA in the acute stage in two cases at the First Hospital of China Medical University from October to December in 2006.

    Ozkan Arat, Yonca; Volpi, John; Arat, Anıl; Klucznik, Richard; Diaz, Orlando

    2011-01-01

    We present the first case of a woman with no significant medical history who developed dissections of bilateral carotid and bilateral vertebral arteries, as well as a retinal artery occlusion, after a roller coaster ride. A 35-year-old woman developed right-sided neck pain followed by a frontal headache immediately after a roller coaster ride. Five days after the incident, she developed complete loss of vision in her right eye for two hours. Subsequently, the vision improved but remained significantly decreased. On presentation, her visual acuity was 20/200 in the right and 20/20 in the left eye. Her fundus exam revealed retinal edema in the superotemporal retinal artery distribution without any visible emboli. Her neurological exam was otherwise normal. The cerebral angiogram showed bilateral internal carotid and vertebral artery dissections. The patient remained stable with conservative therapy without further worsening of vision or any new neurological deficits. Outcomes for cervicocephalic arterial dissection are usually favorable, but early diagnosis is critical for initiation of appropriate treatment of possible complications. Physicians must have a high index of suspicion for arterial dissection when patients note any headache, neck pain or vertigo triggered by violent motion after leisure activities such as roller coaster rides.

    Renal artery dissection may be caused by iatrogenic injury, trauma, underlying arterial diseases such as fibromuscular disease, atherosclerotic disease, or connective tissue disease. Radiological imaging may be helpful in detecting renal artery pathology, such as renal artery dissection. For patients with acute, isolated renal artery dissection, surgical treatment, endovascular management, or medical treatment have been considered effective measures to preserve renal function. We report a case of renal infarction that came about as a consequence of renal artery dissection.

    Pulmonary arterial dissection is an uncommon but usually a deadly complication of chronic pulmonary hypertension. A 26-year-old female patient was admitted to our clinics with sudden dyspnea and chest discomfort one hour after giving birth to twins by vaginal delivery. An echocardiography was performed with a pre-diagnosis of pulmonary embolism. However, echocardiographic examination revealed a dilated main pulmonary artery and a dissection flap extending from main pulmonary artery to left pulmonary artery. In summary, in this report, we described a very rare case of pulmonary artery dissection in a pregnant patient with a previously un-diagnosed patent ductus arteriosus without an obvious rise in pulmonary artery pressure and reviewed the relevant literature.

    2015-10-01

    Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. Clinical presentation ranges from chest pain alone to ST-segment-elevation myocardial infarction, ventricular fibrillation, and sudden death. The treatment of patients with spontaneous coronary artery dissection is challenging because the disease pathophysiology is unclear, optimal treatment is unknown, and short- and long-term prognostic data are minimal. We report the case of a 70-year-old woman who presented with an acute ST-segment-elevation myocardial infarction secondary to a spontaneous dissection of the left anterior descending coronary artery. She was treated conservatively. Cardiac tamponade developed 16 hours after presentation. Repeat coronary angiography revealed extension of the dissection. Medical therapy was continued after the hemopericardium was aspirated. The patient remained asymptomatic 3 years after hospital discharge. To our knowledge, this is the first reported case of spontaneous coronary artery dissection in association with cardiac tamponade that was treated conservatively and had a successful outcome.

    There are no reliable data from randomised trials to decide whether anticoagulants or antiplatelet agents are better to prevent further thromboembolic events after cervical arterial dissection. Most neurologists favour anticoagulants based on the underlying pathology and the likely course of acute post-dissection thromboembolism.

  13. Cervical artery dissection following a turbulent flight.

    Quinn, Colin

    2012-01-31

    BACKGROUND: Cervical artery dissection is a common cause of stroke in young patients without vascular risk factors and may affect the carotid or vertebral arteries. The risk of spontaneous dissection is higher in those with genetic predisposing factors while other cases may be precipitated by an event involving head or neck movement or associated with direct neck trauma. CASE REPORT: We present the case of a previously well young woman with a history of migraine who developed internal carotid artery dissection following a turbulent short-haul commercial flight while restrained using a seatbelt. DISCUSSION: We propose that repetitive flexion-hyperextension neck movements encountered during the flight were the most likely precipitant of carotid artery dissection in this case and review the therapeutic options available.

    Spontaneous coronary artery dissection is an important etiology of nonatherosclerotic acute coronary syndrome, myocardial infarction, and sudden death. Innovations in the catheterization laboratory including optical coherence tomography and intravascular ultrasound have enhanced the ability to visualize intimal disruption and intramural hematoma associated with SCAD. Formerly considered "rare," these technological advances and heightened awareness suggest that SCAD is more prevalent than prior estimates. SCAD is associated with female sex, young age, extreme emotional stress, or extreme exertion, pregnancy, and fibromuscular dysplasia. The clinical characteristics and management strategies of SCAD patients are different than for atherosclerotic heart disease and deserve specific consideration. This review will highlight recent discoveries about SCAD as well as describe current efforts to elucidate remaining gaps in knowledge.

    Full Text Available A 46-year-old male with a history of hypertension visited the emergency department (ED by ambulance complaining of sudden pain in the left side of his back. Ultrasonography (USG performed at ED revealed splenic infarction along with occlusion and dissection of the celiac and splenic arteries without abdominal artery dissection. Contrast enhanced computed tomography (CT revealed the same result. Consequently, spontaneous isolated celiac artery dissection (SICAD was diagnosed. Because his blood pressure was high (159/70 mmHg, antihypertensive medicine was administered (nicardipine and carvedilol. After his blood reached optimal levels (130/80 mmHg, symptoms disappeared. Follow-up USG and contrast enhanced CT performed 8 days and 4 months after onset revealed amelioration of splenic infarction and improvement of the narrowed artery. Here, we report a case of SICAD with splenic infarction presenting with severe left-sided back pain and discuss the relevance of USG in an emergency setting.

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram.

    Full Text Available The aim of this study was to analyze the spectrum of clinical presentations of internal carotid artery dissection. Twenty-two patients with internal carotid artery dissection, mean age 39.02, were evaluated over the past ten years. Magnetic resonance imaging and magnetic resonance angiography were used to establish the diagnosis. Facial and neck pain and Horner’s syndrome were the only presenting symptoms in 4 patients (without brain infarction; facial pain, Horner’s syndrome and contralateral sensorimotor deficit in 6; headache and contralateral sensorimotor deficit in 2; contralateral sensorimotor deficit with or without speech impairment in 10. Internal carotid artery dissection was triggered by a trauma in 7, whereas it was spontaneous in 15. Magnetic resonance imaging revealed infarction in 18 patients. A good outcome (modified Rankin score 0-2 was seen in 20 patients. The spectrum of clinical presentations of internal carotid artery dissection is variable. Internal carotid artery dissection is not necessarily accompanied by infarction on magnetic resonance imaging.

    A 51-year-old man was admitted with right hemiparesis during scuba diving, without headache. Brain magnetic resonance (MR) imaging depicted high-intensity areas in the left superior frontal and cingulate gyri on diffusion-weighted imaging. Dissection of the anterior cerebral artery (ACA) was detected using axial MR angiography and 3-dimensional MR cisternography. Dissection of the ACA during and after scuba diving has not been reported before. Dissection of the arteries should be included in the differential diagnosis when neurologic symptoms occur both during and after scuba diving, even if the patient does not experience headache. Furthermore, the combination of MR cisternography and MR angiography is useful to detect ACA dissection.

    Acute abdominal pain is one of the most common conditions encountered in the emergency department. The differential diagnosis of acute abdominal pain is extensive and identifying the underlying etiology can be challenging. We report a case of acute transient ischemic jejunitis due to symptomatic isolated superior mesenteric artery dissection in a patient with no cardiovascular risk factors or autoimmune diseases. Symptomatic isolated superior mesenteric artery dissection is a rare cause of acute abdominal pain usually treated in the surgical department. The patient had criteria for conservative treatment and rapidly recovered. We highlight a rare condition which should be taken into account for the differential diagnosis of acute abdominal pain.

    Full Text Available Postcoital artery dissection is a rare condition. Here we report a 40-year-old male patient with painful Horner syndrome related to postcoital internal carotid artery (ICA dissection. In neurologic examination of the patient, semiptosis, enophthalmus, and myosis were observed on the left side. There were no carotid bruits. On T1-weighted and fat-suppressed cranial MRI, hyperintensity consistent with intramural hematoma was observed within cervical and temporal petrous segments of left ICA. On cervical and cranial MRA, marked decrease in the calibration of C1 and C2 segments of the left ICA was remarkable. The patient was diagnosed as left ICA dissection and anticoagulant therapy was initiated. A prominent improvement was noted in clinical findings during two months of followup period.

  1. Fatal dissection of the pulmonary artery in pulmonary arterial hypertension

    2009-09-01

    Full Text Available A 41-yr-old patient with chronic stable idiopathic pulmonary arterial hypertension (PAH presented with sudden chest pain and unusual dyspnoea during physical exertion. The patient had been diagnosed with PAH at the age of 12 yrs and was in New York Heart Association functional class I/II. The patient was being treated with an anticoagulant regimen, low-dose diuretics and continuous intravenous epoprostenol therapy. A computed tomography scan showed ancient massive thrombi in dilated central pulmonary arteries, which were not haemodynamically significant (perfusion lung scans did not demonstrate segmental or larger defects, and extensive dissection of the right pulmonary artery starting from the intermediate branch. Due to the extensiveness of the dissection, the patient was immediately considered for heart–lung transplantation, but died 72 h after the onset of symptoms. Permission for post mortem examination was denied. Pulmonary artery dissection should be suspected in PAH patients presenting with chest pain and worsening dyspnoea. In the current case, the factors possibly associated with increased risk for dissection may include dilatation of the pulmonary artery, local inflammation favoured by in situ thrombosis, and acute increase of pulmonary pressure secondary to physical exertion. Extensive pulmonary artery dissection is a life-threatening complication of PAH, and urgent heart/lung transplantation might be the treatment of choice in eligible patients. In addition, better identification of the risk factors for pulmonary artery dissection may help in considering transplantation for selected patients at risk.

    Single-vessel cervical arterial dissections typically occur in young adults and are a common cause of cerebral ischemia and stroke. Although the pathogenesis of multivessel dissection is unclear, it is thought to be a consequence of underlying collagen vascular disease. We present a 34-year-old previously healthy man who developed bilateral internal carotid and vertebral artery dissection following chiropractic manipulation. (orig.)

    Angiographic, CT and MR findings, precipitating factors, and clinical features of spontaneous intracranial internal carotid artery dissection, in particular the terminal segment of the ICA, are described. Patients who had a possible posttraumatic dissection were excluded from the study. Six patients, 3 men and 3 women, mean age 25.8 years, were studied. Spontaneous ICA dissection accounted for 0.63 percent of 797 patients with ischemic stroke and 14 percent of 36 patients with ischemic stroke who were 45 years of age or younger. Headache was absent in two but clearly preceded the onset of cerebral stroke in four patients, the interval ranging from less than a few minutes to 6 hours. Focal cerebral ischemic symptoms were present in all six patients. Four presented with loss of consciousness. Only one patient had a subarachnoid hemorrhage (SAH). Dissection occurred at the level of the carotid knee portion just beyond the origin of the ophthalmic artery in all the patients. Moreover, there was additional involvement of the ipsilateral MCA in four and ipsilateral ACA in three. Angiographic features of the six ICAs that involved dissection were a smooth tapered luminal narrowing or occlusion in two patients, irregular narrowing in three, a pearl and string sign in one, and retention of the contrast media in three. Follow up angiography or magnetic resonance (MR) angiography was performed on all the patients. The interval from the initial to follow-up angiography was one to six months. Stenosis persisted in one artery but was resolved in the other five arteries. MR angiography showed segmental narrowing of the right supraclinoid internal carotid artery in one patient. MR angiographic source images showed a narrow lumen in the right intracavernous portion of the ICA and a crescent-shaped filling defect. Follow-up MR imaging and MR angiography, 6 months after the initial study, showed amelioration of the luminal narrowing and no filling defect. The filling defect is

    Spontaneous internal carotid artery (ICA) dissection (sICAD) results from an intimal tear located around the distal carotid sinus. The mechanisms causing the tear are unknown. This case-control study tested the hypotheses that head movements increase the wall stress in the cervical ICA and that the stress increase is greater in patients with sICAD than in controls. Five patients with unilateral, recanalized, left sICAD and five matched controls were investigated before and after maximal head rotation to the left and neck hyperextension after 45° head rotation to the left. The anatomy of the extracranial carotid arteries was assessed by magnetic resonance imaging and used to create finite element models of the right ICA. Wall stress increased after head movements. Increases above the 80th and 90th percentile were located at the intimal side of the artery wall from 7.4 mm below to 10 mm above the cranial edge of the carotid sinus, i.e., at the same location as histologically confirmed tears in patients with sICAD. Wall stress increase did not differ between patients and controls. The present findings suggest that wall stress increases at the intimal side of the artery wall surrounding the distal edge of the carotid bulb after head movements may be important for the development of carotid dissection. The lack of wall stress difference between the two groups indicates that the carotid arteries of patients with carotid dissection have either distinct functional or anatomical properties or endured unusually heavy wall stresses to initiate dissection.

    The authors analyzed 30 patients whose celiac artery or its branches were dissected during the procedure of transcatheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) and were followed up angiographically. The incidence of arterial dissection was 1.25%. The dissection occurred most frequently in the celiac artery (40% 12/30) and the proper hepatic artery (28% 7/30). The frequency of arterial dissection was affected by the status of the vessel and the experience of the operator. The follow-up angiography revealed complete recanalization in 40% (12/30), irregularity and narrowing of the lumen in 23% (7/30), pseudoaneurysm formation in 23% (7/30), and complete obstruction in 13% (4/30) of the cases. The rate of recanalization in the celiac artery was lower than that of any other arteries in our series. Recanalization to a certain degree without therapeutic intervention was observed in 72% of the dissected arteries enabling and contributing to subsequent successful TAE within 2 months in 78% of the patients with the dissection.

    Full Text Available A 46-year-old male with juvenile myoclonic epilepsy was admitted to the neurological department for convulsive seizures just after lamotrigine was discontinued. On admission he was awake but had a right-sided hemiparesis with Babinski sign and ataxic finger-nose test on the left side. An MR scan showed a left-sided pontine infarction, an infarct in the left cerebellar hemisphere and a right vertebral artery dissection (VAD. The patient was treated with heparin and an oral anticoagulant for 6 months. Recovery of neurologic function was excellent. In patients with symptoms of disturbances of posterior circulation after epileptic seizures, VAD should be considered.

  7. "Ostrich sign" indicates bilateral vertebral artery dissection.

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    Spontaneous dissections of intracranial arteries are rare, but important causes of stroke, especially in younger patients. Dissections of the anterior cerebral artery (ACA) have been reported only very rarely in the European and North American populations but might be more prevalent than previously thought. This paper describes the presenting pattern of the disease, the clinical and imaging findings, as well as endovascular therapeutical options with respect to a meta-analysis of cases reported in the literature. Additionally, own observations in three recent representative cases are discussed. Overall, 80 cases from recent literature were included to the meta-analysis. The median age was 51 (35-82) years. Ischemia alone was described in 58 cases (73 %), subarachnoid hemorrhage (SAH) in 8 cases (10 %), and a combination of both in 14 cases (17 %). Radiological diagnosis including use of thin-layered 3T-MRI vessel wall imaging with black blood technique was verified by double lumen, by a string sign or string and pearl sign, or by a vessel wall hematoma in 23 (32 %), 62 (89 %), and 14 (20 %) cases, respectively. Interventional or surgical treatment was performed in 7 cases. A good clinical recovery was achieved in 77 % of cases. Dissections of the ACA mostly cause ischemia, but can cause SAH or a combination of both in a relatively young population. Detailed neuroradiological diagnosis including 3T-MRI vessel wall imaging is required as a double lumen, isolated stenosis due to vessel wall hematoma, or the secondary development of a pseudoaneurysm might occur. Interventional therapy is the primary therapy for these vascular complications. (orig.)

    2014-11-01

    Full Text Available A 60-year-old woman with mitral valve prolapse, chronic low back pain, and a 30-pack year smoking history presented for a second admission of poorly controlled mid-back pain 10 days after her first admission. She had concomitant epigastric pain, sharp/burning in quality, radiating to the right side and to the mid-back, not associated with food nor improving with pain medications. She denied nausea, vomiting, diarrhea, constipation, dark stools, or blood per rectum. Our purpose was to determine the cause of the patient's epigastric pain. Physical examination revealed epigastric and mid-back tenderness on palpation. Labs were normal except for a hemoglobin drop from 14 to 12.1 g/dL over 2 days. Abdominal ultrasound and subsequent esophagogastroduodenoscopy were normal. Contrast-enhanced abdominal computed tomographic (CT scan revealed the development of a spontaneous celiac artery dissection as the cause of the epigastric pain. The patient was observed without stenting and subsequent CT angiography 4 days later did not reveal worsening of the dissection. She was discharged on aspirin and clopidogrel with outpatient follow-up. Thus far, less than 100 cases of isolated spontaneous celiac artery dissections have been reported. The advent of CT scans and magnetic resonance imaging has increasingly enabled its detection. Risk factors may include hypertension, arteriosclerosis, smoking, and cystic medial necrosis. There is a 5:1 male to female ratio with an average presenting age of 55. Management of dissections may include surgical repair, endovascular stenting, and selective embolization. Limited dissections can be managed conservatively with anti-platelet and/or anticoagulation agents and strict blood pressure control, as done in our patient.

    Carotid artery dissection is an important cause of ischemic stroke in all age groups, particularly in young patients. The purpose of this work was to assess whether there is an association between the presence of an internal carotid artery dissection (ICAD) and the arterial tortuosity. This study considered 124 patients (72 males and 52 females; median age 57 years) with CT/MR diagnosis of ICAD of the internal carotid artery were considered in this multi-centric retrospective study. The arterial tortuosity was evaluated and, when present, was categorized as elongation, kinking, or coiling. For each patient, both the right and left sides were considered for a total number of 248 arteries in order to have the same number of cases and controls. Fisher's exact test was applied to test the association between elongation, kinking, coiling, dissection, and the side affected by CAD. Fisher's exact test showed a statistically significant association between the ICAD and kinking (p = 0.0089) and coiling (p = 0.0251) whereas no statistically significant difference was found with arterial vessel elongation (p = 0.444). ICAD was more often seen on the left side compared to the right (p = 0.0001). These results were confirmed using both carotid arteries of the same patient as dependent parameter with p = 0.0012, 0.0129, and 0.3323 for kinking, coiling, and elongation, respectively. The presence of kinking and coiling is associated with ICAD. (orig.)

    We present a case of a 66-year-old lady with chest pain, without dynamic 12-lead electrocardiographic (ECG) changes and normal serial troponin. Coronary angiography revealed a linear filing defect in the first obtuse marginal branch of the circumflex artery indicating coronary artery dissection, with superadded thrombus. She was managed medically with dual antiplatelet therapy and has responded well. Spontaneous coronary artery dissection (SCAD) is a rare cause of cardiac chest pain, which can be missed without coronary angiography. Unlike most other lesions in patients with unstable symptoms, where coronary intervention with stenting is recommended, patients with SCAD generally fare better with conservative measures than with intervention, unless there is hemodynamic instability.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death. It should be suspected in every healthy young woman without cardiac risk factors, especially during the peripartum or postpartum periods. It is important to check for a history of drug abuse, collagen vascular disease or blunt trauma of the chest. Coronary angiography is essential for diagnosis and early management. We wonder whether thrombolysis might aggravate coronary dissection. All types of treatment (medical therapy, percutaneous intervention or surgery) improve the prognosis without affecting survival times if used appropriately according to the clinical stability and the angiographic features of the involved coronary arteries. Prompt recognition and targeted treatment improve outcomes. We report a case of SCAD in a young female free of traditional cardiovascular risk factors, who presented six hours after thrombolysis for ST elevation myocardial infarction. Coronary angiography showed a dissection of the left anterior descending and immediate branch. She had successful coronary artery bypass grafting, with complete healing of left anterior descending dissection.

    We report the case of a 41-year-old woman who underwent cervical total disc replacement at C4C5 and C5C6 levels and fusion at C6C7 level through an anterior right-side approach. After anesthesia recovery, the patient presented left hemiparesia and facial palsy due to large right hemispheric stroke. Diffusion-weighted magnetic resonance imaging was performed as soon as the patient developed neurologic symptoms of stroke and revealed a right internal carotid artery dissection. Digital substraction angiography, endovascular stenting, angioplasty and thrombectomy were performed. Six months after treatment, clinical examination showed mild left-arm spasticity. To the best of our knowledge, only two cases of internal carotid artery stroke without dissection or thrombosis are reported. In conclusion, although vascular complications are rare after anterior cervical spine procedure, internal carotid artery dissection can occur. Suspected risk factors are prolonged retraction of the carotid artery and neck extension.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. It occurs predominantly among younger females and typically in the absence of atherosclerotic coronary artery disease. It is associated with peripartum period, connective tissue disorders, vasculitides, and extreme exertion. Presentations vary greatly, and this condition can be fatal. Given its rarity, there are no guidelines for management of SCAD. We present the cases of two female patients, with no coronary artery disease risk factors or recent pregnancy, who were presented with non-ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial infarction (STEMI), respectively, secondary to SCAD. Both had excellent outcome after emergent percutaneous intervention. Our first patient was presented with NSTEMI with ongoing chest pain and dynamic electrocardiogram (ECG). Emergent left heart catheterization was significant for first obtuse marginal (OM1) dissection, confirmed by optical coherence tomography. Percutaneous coronary intervention (PCI) with two bare metal stents was performed with resolution of symptoms and ECG changes. The second patient is known to have syndrome, presented with STEMI and emergent coronary angiography showed left anterior descending dissection with intramural hematoma confirmed by intravascular ultrasound and treated with a drug-eluting stent with resolution of symptoms and ST changes. Her hospital course was complicated by post-myocardial infarction pericarditis that was improved with colchicine. Both the patients were observed in the coronary care unit for 24 hours. Both remained asymptomatic at 6-month follow-up. SCAD is a rare cause of acute coronary syndrome. In patients with early presentation, limited disease, and ongoing symptoms, emergent cardiac catheterization with percutaneous intervention has excellent outcome. More studies are needed to establish evidence-based management guidelines.

    Full Text Available Pulmonary artery dissection is extremely rare but it is a really life-threatening condition when it happens. Most patients die suddenly from major bleeding or tamponade caused by direct rupture into mediastinum or retrograde into the pericardial sac. What we are reporting is a rare case of a 46-year-old female patient whose pulmonary artery dissection involves both the pulmonary valve and right pulmonary artery. The patient had acute chest pain and severe dyspnea, and the diagnosis of pulmonary artery dissection was confirmed by ultrasonography and CT angiography. Moreover, its etiology, clinical manifestations, and management are also discussed in this article.

    2010-01-01

    BACKGROUND: Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive human tumors. At present, surgical resection is the only potentially curative treatment. Early neck division is inadequate when invasion of the superior mesenteric artery (SMA) is suspected or in cases of replaced or accessory right hepatic artery. Malignant periampullary tumors often invade retroperitoneal peripancreatic tissues and a positive resection margin is associated with a poor long-term survival. DATA SOURCES: English-language medical databases, PubMed, ELSEVIER and SPRINGERLINK, were searched for articles on"posterior approach pancreaticoduodenectomy","superior mesenteric artery ifrst approach", "retroperitoneal tissue","hanging maneuver", and related topics. RESULTS:The modiifcation allowed the surgeon to early identify the nonresectability of a replaced right hepatic artery if present, enabling complete dissection of the right side of the SMA and portal vein as well as complete excision of the retroportal pancreatic lamina. CONCLUSION: Pancreaticoduodenectomy with early retro-pancreatic dissection is a useful and safe technical variant, which is indicated for the improvement of the safety and curative effect of the procedure.

    A non-bifurcating cervical carotid artery is a rare anomaly in the population. Radiologic diagnosis of pathologies seen together with this anomaly can be challenging. Despite not being diagnostic all the time, digital subtraction angiography is accepted as the gold standard method for the diagnosis of dissection. We present a case of a non-bifurcating cervical carotid artery and concomitant dissection, which presented to the hospital with trauma and ischemic findings.

    Full Text Available ABSTRACTBackground and Purpose: The pathogenesis of spontaneous cervical artery dissections (sCAD and its best medical treatment are debated. This may be due to a lack of clear classification of sCAD. We propose the new Borgess classification of sCAD, based on the presence or absence of intimal tear as depicted on imaging studies and effect on blood flow. Materials and Methods: This is a single-center investigator-initiated registry on consecutive patients treated for sCAD. In the Borgess classification, type I dissections have intact intima and type II dissections have an intimal tear. Results: Forty-four patients and 52 dissected arteries were found. Forty-nine of 52 dissections (93% were treated with dual anti-platelet therapy. Twenty-one of 52 dissections were type I; 31 were type II. Type I dissections were more likely to present with ischemic symptoms (stroke, TIA (p=0.001. More type I dissections occurred in the vertebral artery, while more type II dissections occurred in the internal carotid artery (p

    CrossFit is a high-intensity strength and conditioning program that has gained popularity over the past decade. Potential injuries associated with CrossFit training have been suggested in past reports. We report three cases of cervical carotid dissection that are associated with CrossFit workouts. Patient 1 suffered a distal cervical internal carotid artery (ICA) dissection near the skull base and a small infarct in Wernicke's area. He was placed on anticoagulation and on follow-up has near complete recovery. Patient 2 suffered a proximal cervical ICA dissection that led to arterial occlusion and recurrent middle cerebral artery territory infarcts and significant neurological sequelae. Patient 3 had a skull base ICA dissection that led to a partial Horner's syndrome but no cerebral infarct. While direct causality cannot be proven, intense CrossFit workouts may have led to the ICA dissections in these patients.

    Full Text Available Spontaneous coronary artery dissection is a rare condition, usually presenting as an acute coronary syndrome, and is often seen in states associated with high systemic estrogen levels such as pregnancy or oral contraceptive use. While topical hormonal replacement therapy may result in increased estrogen levels similar to those documented with oral contraceptive use, there are no reported cases of spontaneous coronary dissection with topical hormonal replacement therapy. We describe a 53-year-old female who developed two spontaneous coronary dissections while on topical hormonal replacement therapy. The patient had no other risk factors for coronary dissection. After withdrawal from topical hormonal therapy, our patient has done well and has not had recurrent coronary artery dissections over a one-year follow-up period. The potential contributory role of topical hormonal therapy as a cause of spontaneous coronary dissection should be recognized.

    Full Text Available Dissection of cervical arteries constitutes a medical emergency. Although relatively rarely, activities classified as sports and recreation may be a cause of arterial dissection independently of neck or head trauma. The purpose of the present paper was to present a series of cases of cerebrum-cervical arterial dissection in individuals during or soon after the practice of these sports activities.Methods Retrospective data on patients with arterial dissection related to sports and recreation.Results Forty-one cases were identified. The most frequently affected vessel was the vertebral artery. A large variety of activities had a temporal relationship to arterial dissection, and jogging was the most frequent of these. This is the largest case series in the literature.Conclusion Arterial dissection may be a complication from practicing sports.

  4. Spontaneous Coronary Artery Dissection following Topical Hormone Replacement Therapy

    Spontaneous coronary artery dissection is a rare condition, usually presenting as an acute coronary syndrome, and is often seen in states associated with high systemic estrogen levels such as pregnancy or oral contraceptive use. While topical hormonal replacement therapy may result in increased estrogen levels similar to those documented with oral contraceptive use, there are no reported cases of spontaneous coronary dissection with topical hormonal replacement therapy. We describe a 53-year...

    Endofibrosis of the external iliac artery is an uncommon disease affecting primarily young, otherwise healthy, endurance athletes. Thigh pain during maximal exercise with quick resolution postexercise is characteristic of the so-called cyclist's iliac syndrome. We report an unusual case in which the typical endofibrotic plaque was accompanied by dissection of the external iliac artery. The patient was treated surgically with excision of the affected artery segment and placement of an interposition graft. This case highlights an unusual finding in association with external iliac artery endofibrosis and provides an opportunity to briefly review the literature on the subject.

    Full Text Available Abstract Introduction Cerebrovascular disease is a major cause of mortality and morbidity worldwide. Ischemic stroke is the most common manifestation, encompassing a wide variety of causative mechanisms. We present the case of a middle-aged male patient with spontaneous coronary artery dissection in the presence of anti-cardiolipin antibodies, leading to left ventricular thrombus and presenting with stroke. Case presentation A 56-year-old Caucasian man presented with dysarthria and right-sided weakness. There was a history of chest pain with autonomic symptoms four days earlier. Examination revealed right-sided hemiparesis. Electrocardiogram showed sinus rhythm with anterior Q waves. Magnetic resonance imaging of the brain showed large left parietal and smaller multiple cerebral infarcts. Echocardiogram showed anterior wall and apical akinesis with a large mural thrombus. Anti-cardiolipin antibodies immunoglobulin G and immunoglobulin M were strongly positive. Coronary angiography showed dissection of the mid left anterior descending artery with normal flow down the distal vessel. He was treated conservatively with anticoagulation and secondary prevention. He was in good health when seen in clinic four months later. Conclusion We highlight the importance of a comprehensive approach at obtaining the correct diagnosis, input of different specialities and the fact that the presence of anti-cardiolipin antibodies is associated with coronary artery dissection in a middle-aged male patient whose presentation was stroke.

    Full Text Available Dissections of the cervical arteries cause about 20% of total juvenile strokes. Approximately 4% of the carotid artery dissections are due to a (polytrauma such as car accidents. Despite improved diagnostic facilities, traumatic dissections are often underdiagnosed or diagnosed too late due to a lack of awareness of potential initial signs and symptoms.We report here a case of a delayed embolic stroke after a car accident caused by a dissection of the carotid artery and subsequent pseudoaneurysm.To reduce the long-term morbidity or mortality of multiple trauma patients, an early detection of cervical carotid and vertebral dissections is strictly necessary.

    2002-12-01

    Medical management of cervical arterial dissections is not standardized and has not been the subject of randomized trials. Management is mainly based on the presumed pathophysiology of secondary cerebral infarcts associated with dissections and the individual experience of each treating team. First, a review of the literature regarding medical management of acute and chronic dissections is presented. Then, results from a national study sponsored by the Société Française Neuro-Vasculaire and the Société Française de Neuro-Radiologie evaluating the medical management of this pathology in French neuro-vascular centers will be presented. These data will be useful to generate practical management recommendations and establish guidelines for further studies.

    2014-02-01

    Dysphagia and hoarseness caused by laryngopharyngeal paralysis associated with internal carotid artery (ICA) dissection is rare. We reported a case which recovered spontaneously. A 57-year old man visited our hospital complaining of dysphagia and hoarseness lasting for two weeks. Paralysis of right vocal fold and rotational movement of the posterior pharyngeal wall toward the left side during swallowing were observed. Magnetic resonance imaging was performed under diagnosis of isolated right vagus nerve paralysis, and dissection of the right ICA was revealed. He was treated conservatively, and both of laryngopharyngeal movement and the ICA dissection were improved completely. There is a possibility that laryngeal paralysis caused by ICA dissection has been misdiagnosed as an idiopathic paralysis.

    This paper studies dissection propagation subject to internal pressure in a residually-stressed two-layer arterial model. The artery is assumed to be infinitely long, and the resultant plane strain problem is solved using the extended finite element method. The arterial layers are modelled using the anisotropic hyperelastic Holzapfel-Gasser-Ogden model, and the tissue damage due to tear propagation is described using a linear cohesive traction-separation law. Residual stress in the arterial wall is determined by an opening angle [Formula: see text] in a stress-free configuration. An initial tear is introduced within the artery which is subject to internal pressure. Quasi-static solutions are computed to determine the critical value of the pressure, at which the dissection starts to propagate. Our model shows that the dissection tends to propagate radially outwards. Interestingly, the critical pressure is higher for both very short and very long tears. The simulations also reveal that the inner wall buckles for longer tears, which is supported by clinical CT scans. In all simulated cases, the critical pressure is found to increase with the opening angle. In other words, residual stress acts to protect the artery against tear propagation. The effect of residual stress is more prominent when a tear is of intermediate length ([Formula: see text]90[Formula: see text] arc length). There is an intricate balance between tear length, wall buckling, fibre orientation, and residual stress that determines the tear propagation.

    Full Text Available Abstract Background To describe a rare presentation of vertebral artery dissection (VAD as a small but congruous incomplete homonymous hemianopia demonstrating use of visual field testing in the diagnosis. Case presentation A 30 year old woman had been unwell for 4 months with difficulty focusing, vertigo, dizziness and a feeling of falling to the right. A small but congruous right inferior homonymous quadrantanopia was found on examination leading to further investigation that uncovered a vertebral artery dissection and multiple posterior circulation infarctions including a left occipital stroke matching the field defect. Conclusions We describe an atypical case of VAD presenting with a small congruous quadrantanopia. This is a rare but significant condition that predisposes to multiple thromboembolic infarction that may be easily misdiagnosed and a high index of suspicion is required to make the diagnosis.

    The criteria for headache attributed to cervical artery dissection have been changed in the new third edition of the International Classification of Headache Disorders (ICHD-III beta). We have retrospectively investigated 19 patients diagnosed from 2001 to 2006 with cervical artery dissection...... at onset and followed them up six months after dissection. At dissection onset 17/19 patients were classified as headache probably attributed to vascular disorder at the time of dissection using the ICHD second edition (ICHD-II) criteria. In contrast, 17/19 of patients fulfilled the ICHD-III beta criteria......-III beta criteria for cervical artery dissection are useful for classifying patients at the first encounter. We show for the first time that persistent headache attributed to arterial dissection is frequent....

  16. A Vertebral Artery Dissection with Basilar Artery Occlusion in a Child

    Directory of Open Access Journals (Sweden)

    Katleen Devue

    2014-01-01

    Full Text Available This paper presents the case report of an 11-year-old boy with an acute dissection with thrombosis of the left vertebral artery and thrombosis of the basilar artery. The patient was treated with acute systemic thrombolysis, followed by intra-arterial thrombolysis, without any clinical improvement, showing left hemiplegia, bilateral clonus, hyperreflexia, and impaired consciousness. MRI indicated persistent thrombosis of the arteria basilaris with edema and ischemia of the right brainstem. Heparinization for 72 hours, followed by a two-week LMWH treatment and subsequent oral warfarin therapy, resulted in a lasting improvement of the symptoms. Vertebral artery dissection after minor trauma is rare in children. While acute basilar artery occlusion as a complication is even more infrequent, it is potentially fatal, which means that prompt diagnosis and treatment are imperative. The lack of class I recommendation guidelines for children regarding treatment of vertebral artery dissection and basilar artery occlusion means that initial and follow-up management both require a multidisciplinary approach to coordinate emergency, critical care, interventional radiology, and child neurology services.

    Spontaneous coronary artery dissection(SCAD) is a rare disease that is usually seen in young women in left descending coronary artery and result in events like sudden cardiac death and acute myocardial infarction. A 70-year-old man was admitted to the emergency department with chest pain which started 1 h ago during a relative’s funeral. The initial electrocardiography demonstrated 2 mm ST-segment depression in leads V1-V3 and the patient underwent emergent coronary angiography. SCAD simultaneously in two different coronary arteries [left anterior descending(LAD) artery and left circumflex(LCx)] artery was detected and SCAD in LCx artery was causing total occlusion which resulted in acute myocardial infarction. Successful stenting was performed thereafter for both lesions. In addition to the existence of SCAD simultaneously in two different coronary arteries, the presence of muscular bridge and SCAD together at the same site of the LAD artery was another interesting point which made us report this case.

    A review of 4,500 angiograms yielded 11 patients with dissection of the vertebral arteries who had MRI and (in 4 patients) MR angiography (MRA) in the acute phase of stroke. One patient with incidental discovery at arteriography of asymptomatic vertebral artery dissection and two patients with acute strokes with MRI and MRA findings consistent with vertebral artery dissection were included. Dissection occurred after neck trauma or chiropractic manipulation in 4 patients and was spontaneous in 10. Dissection involved the extracranial vertebral artery in 9 patients, the extra-intracranial junction in 1, and the intracranial artery in 4. MRI demonstrated infarcts in the brain stem, cerebellum, thalamus or temporo-occipital regions in 7 patients with extra- or extra-intracranial dissections and a solitary lateral medullary infarct in 4 patients (3 with intracranial and 1 with extra-intracranial dissection). In 2 patients no brain abnormality related to vertebral artery dissection was found and in one MRI did not show subarachnoid haemorrhage revealed by CT. Intramural dissecting haematoma appeared as crescentic or rounded high signal on T1-weighted images in 10 patients examined 3-20 days after the onset of symptoms. The abnormal vessel stood out in the low signal cerebrospinal fluid in intracranial dissections, whereas it was more difficult to detect in extracranial dissections because of the intermediate-to-high signal of the normal perivascular structures and slow flow proximal and distal to the dissection. In two patients examined within 36 h of the onset, mural thickening was of intermediate signal intensity on T1-weighted images and high signal on spin-density and T2-weighted images. MRA showed abrupt stenosis in 2 patients and disappearance of flow signal at and distal to the dissection in 5. Follow-up arteriography, MRI or MRA showed findings consistent with occlusion of the dissected vessel in 6 of 8 patients. (orig.). With 7 figs., 3 tabs.

    Myocardial infarction complicates approximately 1 in 10,000 pregnancies. Although coronary artery dissection is the leading cause of pregnancy-related myocardial infarction during the postpartum period, the pathogenesis of coronary dissection during this period remains uncertain.Herein, we report the case of a 52-year-old black postmenopausal woman with no apparent cardiovascular risk factors who gave birth to twins after in vitro fertilization. Ten days after delivery, she presented with an acute coronary syndrome. Coronary angiography revealed dissection of all 3 coronary arteries. Despite aggressive medical management, the patient experienced recurrent myocardial ischemia. Repeat coronary angiography revealed progression of the dissection process, which required urgent coronary artery bypass surgery. The patient's postoperative course was uneventful. To our knowledge, this report is the 1st description of pregnancy-associated coronary artery dissections in a postmenopausal woman, and the 1st such event in a pregnancy that resulted from in vitro fertilization.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome occurring predominantly in young women without any cardiovascular risk factors, especially during the peripartum and early postpartum period. Here, we report a case of a 28-year-old pregnant woman who was found to have an isolated distal SCAD of the left anterior descending artery (LAD). Coronary angiography was complicated by extensive LAD and circumflex arteries dissection, requiring an emergency coronary artery bypass grafting associated with ventricular assist device implantation and underlying the extreme fragility of coronary arteries in pregnant women.

    We present a case of a 34-year-old male who presented to the emergency ward with fever and abdominal pain. The diagnosis of Takayasu's arteritis and also antiphospholipid syndrome was made during an imaging workup of deep-vein thrombosis. A spontaneous coronary artery dissection was revealed in coronary CT angiography requested for chest pain and dyspnea. The patient was treated medically and discharged on close followup. The concurrence of spontaneous coronary artery dissection with antiphospholipid syndrome and Takayasu's arteritis has not been reported in the previous literature. The possibility of a spontaneous coronary artery dissection should be considered in patients presenting with both diseases.

Havia hipertensão pulmonar com arteriopatia plexogênica grave; nas grandes artérias elásticas, a camada média tinha alterações necróticas e reparadoras profundas. Discute-se o papel da medionecrose, condição que é exacerbada pela hipertensão e por características individuais, na patogenia do aneurisma dissecante e no caso em questão. A análise da literatura mostra que, na artéria pulmonar, a dissecção é sempre um acidente fatal, por rotura ou obstrução arterial. O tratamento desta intercorrência, eminentemente cirúrgico, raramente é possível, devido ao caráter fulminante da evolução e à ausência de sinais definidos para o diagnóstico em tempo hábil.The author presents a case of a 13-year old girl with pulmonary trunk dissection and rupture with a cardiac tamponade. There was a ductus arteriosus persistent and a non stenotic bicuspid pulmonary valve. A plexogenic pulmonary arteriopathy and severe process of injury and repair in the elastic vessels are present. The significance of medionecrosis in the pathogenesis ot pulmonary dissection is discussed. An analysis of reports in dissecting pulmonary aneurysm reveals a fatal outcome in the vast majority of them, due either to arterial rupture or obstruction.

    Spontaneous renal artery dissection (SRAD) is rare and presents a diagnostic and therapeutic challenge. We report a case of a 36-year-old man who had an SRAD-complicated renal infarction. The patient experienced severe unilateral flank pain. Enhanced abdominal computed axial tomography scan showed renal infarction, and urinalysis showed no hematuria. Selective renal angiography was essential to evaluate the extent of dissection and suitability for repair. The patient was treated with catheter-directed thrombolysis and frenal artery stenting.

    Spontaneous renal artery dissection (SRAD) is a rare entity. We reported a 30-year-old healthy man presenting with sudden onset of left flank pain. Abdominal plain film and sonography were unremarkable. The contrast-enhanced abdominal computed tomographic (CT) scan demonstrated a dissecting intimal flap of the left distal renal artery (RA) complicating infarction. Selective angiography of the renal artery disclosed a long dissection of left distal RA with a patent true lumen and occlusion of left accessory RA. Conservative treatment with control of blood pressure and antiplatelet agent was prescribed. The patient was discharged with an uneventful condition on day 5.

    2014-06-01

    Full Text Available A 46-year-old woman was admitted to our hospital with mild right-sided hemiparesis and orthostatic hypotension. Magnetic resonance angiography of the neck showed stenosis of the left distal carotid sinus surrounded by intraluminal hyperintensities on both T1-weighted and T2-weighted images, representing a periluminal hematoma secondary to carotid artery dissection. The dissection hyperextended the carotid artery wall and stimulated baroreceptors in the carotid sinus. The stimulated baroreceptors induced carotid sinus hypersensitivity, which may have been related to her orthostatic hypotension. Post-stroke orthostatic hypotension should prompt consideration of carotid artery dissection.

    2014-01-01

    Full Text Available Background: Some complications related to vertebral artery occlusion by endovascular technique have been reported. However, cerebellar hemorrhage after vertebral artery occlusion in subacute phase is rare. In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive therapy for vasospasm after embolization of a vertebral dissecting aneurysm. Case Description: A 56-year-old female with a ruptured vertebral dissecting aneurysm proximal to the posterior inferior cerebellar artery developed cerebellar hemorrhage 15 days after embolization of the vertebral artery, including the dissected site. In this patient, the preserved posterior inferior cerebellar artery fed by retrograde blood flow might have been hemodynamically stressed during hypertensive and antiplatelet therapies for subarachnoid hemorrhage, resulting in cerebellar hemorrhage. Conclusion: Although cerebellar hemorrhage is not prone to occur in the nonacute stage of embolization of the vertebral artery, it should be taken into consideration that cerebellar hemorrhage may occur during hypertensive treatment.

    We report three families with arterial aneurysms and dissections in which variants predicted to be pathogenic were identified in SMAD2. Moreover, one variant occurred de novo in a proband with unaffected parents. SMAD2 is a strong candidate gene for arterial aneurysms and dissections given its role in the TGF-β signaling pathway. Furthermore, although SMAD2 and SMAD3 probably have functionally distinct roles in cell signaling, they are structurally very similar. Our findings indicate that SMAD2 mutations are associated with arterial aneurysms and dissections and are in accordance with the observation that patients with pathogenic variants in genes encoding proteins involved in the TGF-β signaling pathway exhibit arterial aneurysms and dissections as key features.

    2006-04-01

    Full Text Available Abstract Background Spontaneous carotid artery dissections have been rarely reported in children. Diagnosis has traditionally been confirmed by catheter arteriography. More recently diagnosis has been made by magnetic resonance imaging and magnetic resonance angiography; however the sensitivity of these techniques has yet to be determined. The authors are unaware of reports of carotid dissection confirmed by dynamic computed tomography (computerized tomographic arteriography in the young. Case presentation We recently evaluated a fourteen year-old male following the development of transient neurologic symptoms. There was no antecedent illness or trauma. Dynamic computed tomography revealed an intracranial dissection involving the supraclinoid segment of the left internal carotid artery (confirmed by catheter arteriography. Studies for vasculitis, pro-thrombotic states, and defects of collagen were negative. Conclusion Spontaneous carotid artery dissection is a potential cause of transient neurological symptoms and ischemic stroke in the pediatric population. Dynamic computed tomography appears to be a reliable diagnostic tool which can lead to early diagnosis.

  13. Cervical artery dissection: early recognition and stroke prevention.

    2016-07-01

    Cervical artery dissections involve the carotid or vertebral arteries. Although the overall incidence is low, they remain a common cause of stroke in children, young adults, and trauma patients. Symptoms such as headache, neck pain, and dizziness are commonly seen in the emergency department, but may not be apparent in the obtunded trauma patient. A missed diagnosis of cervical artery dissection can result in devastating neurological sequelae, so emergency clinicians must act quickly to recognize this event and begin treatment as soon as possible while neurological consultation is obtained. This issue reviews the evidence in applying advanced screening criteria and choosing imaging and antithrombotic treatment strategies for patients with cervical artery dissections to reduce the occurrence of ischemic stroke.

Dissections of carotid and vertebral arteries in neck account for about 20% of strokes in young compared with 2.5% in the elderly. Three patients of vertebral artery dissection related to indirect neck trauma are described. The first patient developed the symptoms while dancing, the second after a trivial fall and the third while he was on a dental chair. None of them had a direct severe neck trauma or concomitant risk factor like hypertension, connective tissue disease or migraine. Clinical symptomatology was similar in all the patients and included occipito-nuchal pain, headache and brain stem dysfunction chiefly in the posterior inferior cerebellar artery (PICA territory. One of the patients also had associated ischaemic myelopathy. MRA and DSA confirmed dissection in all with a predominant steno-occlusive picture. Cases of so called trivial neck movement/torsion related dissection have been described previously but have not received any major importance. Usually classified as ′spontaneous′ or ′traumatic′, there is a possible ambiguity in literature about appropriate terminology. We emphasise that a history of such subtle precipitating events be taken while diagnosing young patients with brain stem strokes, to recognise this clinical entity. Although mechanisms are not absolutely clear, yet there seems to be an important relationship between arterial dissection and neck movements or minor trauma.

    @@ The left internal mammary artery (LIMA) had become the conduit of choice for myocardial revascularization, since it has been proved that 10 years patency rates of LIMA grafts are more than 90%. 1,2 The arterial graft trunk dissection is a rare event, affecting the procedure effects and related to reoperation.3 According to Kim and coworker's study,4 the arterial graft trunkdelayed dissection manifested by early post-operative angiography only occurred in 6 of 1111 of the off-pump coronary artery bypass grafts. So up to now, the consequence of dissections without severe hemodynamicabnormality is beyond our knowledge.

    Full Text Available Objective To discuss the individualized management strategy for intracranial vertebral artery dissecting aneurysms. Methods Eighteen patients with intracranial vertebral artery dissecting aneurysms were treated with different surgical methods. Results Eighteen patients underwent different surgical treatment. Five patients underwent complete occlusion of the aneurysm and parent artery by coiling, 5 were treated by stent -assisted coiling (3 densely packed coiling and 2 non-densely packed coiling, 4 underwent stent-only therapy and 3 of them presented hemodynamic improvement after surgery, 3 were treated by direct surgical clipping, and 1 underwent occipital artery-posterior inferior cerebellar artery bypass. Two aneurysms ruptured immaturely, in which one patient died on the third day after operation and one patient occurred moderate disablity. Only 1 patient who underwent complete occlusion of aneurysm and parent artery presented temporarily ischemic symptoms. No adverse effects were seen in other patients. Seventeen patients were followed up for 1 month to 3 years, and all the aneurysms were stable. Conclusion There are many kinds of therapeutic methods for intracranial vertebral artery dissecting aneurysms. The patients should be treated according to several factors such as the clinical manifestations, aneurysm configuration, and relationship with the posterior inferior cerebellar artery. The treatment should be individualized.

  17. Acute occlusion of the left subclavian artery with artery dissection

    @@ Subclavian steal syndrome is cerebral or brain stem ischemia resulting from diversion of blood flow from the basilar artery to the subclavian artery, which is caused by occlusive disease of either the subclavian artery or the innominate artery before they branch off at the vertebral artery. In the patients with subclavian steal syndrome the subclavian artery is fed by retrograde flow from the vertebral artery via the carotids and the circle of Willis.

    Coronary artery injury such as acute coronary dissection is an uncommon and potentially life-threatening complication after blunt chest trauma. The authors report an unusual autopsy case of a 43-year-old healthy man who suddenly collapsed after receiving a punch to the chest during the practice of kung fu. The occurrence of the punch was supported by the presence of one recent contusion on the left lateral chest area at the external examination and by areas of hemorrhage next to the left lateral intercostal spaces at the internal examination. The histological examination revealed the presence of an acute dissection of the proximal segment of the left anterior descending coronary artery. Only few cases of coronary artery dissection have been reported due to trauma during sports activities such as rugby and soccer games, but never during the practice of martial arts, sports usually considered as safe and responsible for only minor trauma.

Methods The echocardiographic appearance of 3 patients with pulmonary artery dissection were analyzed retrospectively. Results Two cases had congenital heart diseases with shunt from the left heart to the right, they were both patent arterial ductus. The other 1 cases was chronic pulmonary heart disease. Severe pulmonary hypertension existed in two cases. Site of the dissection, abradant endomembrane and its crevasse could be clearly seen by echocardiography. Conclusion Pulmonary artery dissection is a rare but lite-threatening disease, it often occurs in patients with pulmonary hypertension and dilation of the main pulmonary and/ or branches. Echocardiography should be the first choice in diagnosis of pulmonary artery dissection.

    2013-01-01

    Full Text Available The paper gives the data available in the literature and the author’s results of an examination of almost 140 patients with dissection of the internal carotid and vertebral arteries (ICA and VA. Dissection is blood penetration through an intimal tear from the lumen of an artery into its wall to develop intramural hematoma (IMH. The cause of dissection is the weakness of the arterial wall presumably due to mitochondrial cytopathy. IMH narrows/occludes the arterial lumen or is a source of arterioarterial embolism, which in turn leads to ischemic stroke. Stroke as a result of dissection generally develops in young patients, who are not prone to traditional vascular risk factors, frequently after the influence of provocative factors (mild head/neck injury, head jerks, physical strain, contraceptives, etc.. The characteristics of stroke are head/neck pain on the side of dissection that appears a few days prior to stroke or simultaneously with the latter; quite often a good recovery of impaired functions; and low recurrence rates. Another major manifestation, isolated cervicocephalic pain, is encountered in PA dissection more frequently (in almost a third of cases and in ICA dissection less frequently (about 5%. Magnetic resonance (MR angiography and fat-saturated T1-weighted MR imaging play a leading role in the verification of dissection. Dissection should be treated with anticoagulants/antiaggregants in its acute phase, as well as with trophic drugs, primarily actovegin, in both acute and chronic phases.

    Vertebral artery dissection (VAD) is among the most common identifiable etiologies of stroke in young adults and poses a diagnostic challenge due to nonspecific symptoms and substantial variability of imaging results. Here, we present a case of unspecific neck pain as isolated symptom of VAD with unusually compelling evidence on duplex ultrasound. This observation has clinical relevance as the absence of any neurological symptoms in our patient highlights the necessity of considering cervical artery dissection in patients presenting with unspecific symptoms such as neck pain, even if isolated. Furthermore, our image of intramural hematoma on duplex ultrasound has been captured in an unusual, clear and distinct fashion and might therefore be a useful reference image in the clinical assessment of patients with a suspicion of cervical artery dissection.

    We report the case of a 26-year-old female patient with Marfan syndrome and an aberrant right subclavian artery (ARSA) with associated Kommerell diverticulum. The patient presented with spontaneous acute dissection of the ARSA that showed fusiform dilation to 4 cm in diameter. Definitive treatment was performed using a two-stage hybrid endovascular technique, including extrathoracic bilateral upper extremity bypass and thoracic endovascular aortic repair with debranching of the right and left subclavian arteries. This was followed by coil and plug embolization to exclude the dissection and prevent subsequent endoleak.

    Full Text Available The use of shockwave lithotripsy is currently the mainstay of treatment in renal calculosis. Several complications including vessel injuries have been implied to extracorporeal shockwave lithotripsy. We report an isolated dissection of the superior mesenteric artery in a 60-year-old male presenting with abdominal pain which occurred three days after extracorporeal shockwave lithotripsy. The patient was treated conservatively and the abdominal pain subsided 24 hours later. The patient's history, the course of his disease, and the timing may suggest a correlation between the dissection and the ESWL.

    To perform high-resolution magnetic resonance imaging (HRMRI) and determine clinical features of patients with acute symptomatic middle cerebral artery (MCA) dissection. Thirteen patients with acute symptomatic MCA dissection underwent HRMRI within 3 days after initial clinical onset. They also underwent routine brain MR imaging. HRMRI examinations included time-of-flight MR angiography (MRA), T2-weighted, T1-weighted, proton-density-weighted, and three-dimensional magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequences. Conventional angiography and MRA were used as reference standard to establish the diagnosis of MCA dissection. The angiographic findings and HRMRI findings such as intimal flap, double lumen, and intramural hematoma were analyzed in this study. All patients presented cerebral ischemia (median National Institutes of Health Stroke Scale score = 4, range = 0-18). String sign was seen on MRA in seven patients. However, double lumen was seen in all patients on HRMRI by intimal flap. High signal lesion on MPRAGE sequences around the dissection lumen due to intramural hematoma was seen in three patients. HRMRI can be used to easily detect the wall structure of MCA such as the intimal flap and double lumen in patients with acute symptomatic MCA dissection. MPRAGE can detect hemorrhage in false lumen of MCA dissection.

    Aneurysms in the pediatric population are a rare pathology with specific features which requires a deep knowledge of their pathogenesis for the best therapeutic choice; the authors report their experience with a patient presenting aneurysm of the middle cerebral artery (MCA) associated with proximal stenosis of the vessel. A six-year-old girl came to our observation after sudden onset of headache and left hemiparesis. Angio-MRI and angio-CT scan showed a right MCA dissecting aneurysms associated with proximal stenosis of the vessel. Patient started a therapy with low molecular weight heparin (LMWH), replaced, 15 days later, with acetyl-salicylic acid (ASA). Patient showed a rapid and almost complete neurological recovery, despite several radiological exams confirmed a complete occlusion of the right MCA. As many other authors noted, dissecting aneurysms in the pediatric population are probably due to a defect of the entire arterial wall. Combination of stenosis, turbulence and partial thrombosis of the aneurysm led to a complete occlusion of artery involved, leading to the formation of collateral circles. In our case, complete thrombosis was probably delayed with anticoagulant therapy and the progressive reinforcement of collateral circles lead to the patient's neurological recovery.

    To evaluate the feasibility of high-resolution MRI (HR-MRI) for diagnosing intracranial vertebrobasilar artery dissection (VBD) and to identify the most useful imaging findings suggesting dissection. We retrospectively reviewed 50 patients with suspected intracranial VBDs who underwent HR-MRI. Two neuroradiologists independently reviewed the HR-MR images. The diagnosis based on HR-MRI was compared with the final diagnosis by consensus among the neuroradiologists, neurointerventionist, and neurologist. Two neuroradiologists also sought signs of dissection (mural hematoma, dissection flap, outer-diameter enlargement on T2WI of steno-occlusive lesions). Inter- and intraobserver agreements were analysed. HR-MRI corroborated the final diagnosis in 47 (94 %; 31 VBD and 16 non-VBD) patients. A mural haematoma was best detected on T1WI and contrast-enhanced (CE)-T1WI (54.3 %). Dissection flaps were observed in almost all cases on CE-T1WI (91.4 %), and then were detected on T2WI (68.6 %). Outer-diameter enlargement of the steno-occlusive lesions on angiography was detected in more than half of the cases (62.9 %). The two reviewers showed almost perfect agreement for the diagnosis of VBD and detecting dissection signs on every sequence. HR-MRI can be a useful and non-invasive diagnostic tool for intracranial VBD, and dissection flaps on CE-T1WI are the signs with the greatest diagnostic value. (orig.)

    Full Text Available The etiology of the vertebral dissecting aneurysms is largely unknown, and they frequently occurs in relatively healthy young men. Objectives and Methods. A series of 57 consecutive cases defined by angiography were evaluated with regard to deviation in the course of the affected and contralateral vertebral arteries. Division was into 3 types: Type I without any deviation, Type II with mild-to-moderate deviation but not over the midline; and Type III with marked deviation over to the contralateral side beyond the midline. Results. The most frequent type of VA running was Type III for the affected and Type I nonaffected side, with this being found in all 17 patients except one. All of the Type III dissections occurred just proximal to a tortuous portion, while in cases with Type-I- and Type-II-affected sides, the majority (33 of 39 occurred near the union of the vertebral artery. In 10 of 57, a non-dominant side was affected, all except one being of Type I or II. With 12 recent patients assessed angiographically in detail for hemodynamics, eleven patients showed contrast material retrograde inflowing into the pseudolumen from the distal portion of the dissection site. Turbulent blood flow was recognized in all of these patients with retrograde inflow. Conclusions. Turbulent blood flow is one etiology of vertebral artery dissection aneurysms, with the sites in the majority of the cases being just proximal to a tortuous portion or union of vessels. In cases with dissection proximal to the tortuous course of the vertebral artery, retrograde inflow will occur more frequently than antegrade, which should be taken into account in designing therapeutic strategies.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    Basilar artery dissection (BAD) is a rare condition with a worse prognosis than a dissection limited to the vertebral artery. We report a rare case of chronic BAD with an associated symptomatic aneurysm presenting with massive subarachnoid hemorrhage (SAH) in a 54-year-old woman. The diagnosis of acute BAD could only be made retrospectively, based on clinical and neuroradiological studies from a hospital admission 10months earlier. Angiography performed after her SAH showed unequivocal signs of imperfect healing; she was either post-recanalization of a complete occlusion or post-dissection. Residual multi-channel intraluminal defects led to the development of a small aneurysm, which was responsible for the massive hemorrhage. The occurrence of an associated aneurysm, and wall disease, but not an intraluminal process, reinforces the diagnosis of dissection. The patient was fully recovered at 90day follow-up. This case reinforces the need for long-term neuroradiological surveillance after non-hemorrhagic intracranial dissections to detect the development of de novo aneurysms.

    Full Text Available Aortic dissection can be fatal in case of underdiagnosis, and early treatment is essential for the survival. Although acute onset of chest or back pain is most common presenting symptoms, some patients might present with atypical findings such as acute stroke, mesenteric ischaemia, renal failure or myocardial infarction. Here, we report two cases presenting emergency room with atypical findings of aortic dissection which diagnosis is made during etiologic work up for ischemic stroke.

    2010-02-01

    Full Text Available Testicular arterial anatomy is important for testicular and renal surgeries. It may vary at the origin and arise from renal artery, suprarenal artery or lumbar artery. During routine dissection of 52-year-old male cadaver; the right testicular artery arising from right aberrant renal artery was found. Anatomical variation of testicular arteries is reported to be 4.7%. Presence of aberrant renal artery is seen in 13–16% of cases only. The origin of right testicular artery from right aberrant renal artery is very rare. Thus knowledge of this type of variation is very important in avoiding complications during operative surgeries.

    We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures.

    Although rare, iatrogenic aortocoronary dissection is one of the complications most dreaded by the interventional cardiologist. If not managed promptly, it can have redoubted and serious consequences. Herein, we present the case of a 70 year-old woman who was treated by stenting of the second segment of the right coronary artery (RCA) for recurrent angina but, unfortunately, the procedure was complicated by anterograde dissection of the RCA with a simultaneous retrograde propagation to the pr...

    Spontaneous cervical artery dissections (sCAD) often occur in otherwise healthy individuals without known risk factors for stroke and frequently develop spontaneously without relevant trauma. An underlying arteriopathy leading to a so-called 'weakness of the vessel wall' and predisposing certain individuals to dissection has often been postulated. Therefore, the morphology of connective tissue, a main component of vessel wall and environment, was investigated in carotids and skin. While the overall morphology of dermal connective tissue is normal, about half of patients with sCAD show mild ultrastructural connective tissue alterations. These ultrastructural morphological aberrations can be designated either as 'Ehlers-Danlos syndrome (EDS) III-like', resembling mild findings in patients with the hypermobility type of EDS (EDS III); or coined 'EDS IV-like' with collagen fibers containing fibrils with highly variable diameters resembling mild findings in vascular EDS; or the abnormalities are restricted to the elastic fibers (with fragmentation and minicalcifications) without significant alterations in the morphology of the collagen fibrils. These findings had some similarity with the morphology found in heterozygous carriers of pseudoxanthoma elasticum. A grading scale according to the severity of the findings has been introduced. Similar connective tissue abnormalities were detected in some first-degree relatives of patients with sCAD showing hereditary at least in a subgroup. They can serve as a phenotypic marker for further genetic studies in patients with sCAD and large families to possibly identify the underlying basic molecular defect(s). Very few of patients (connective tissue abnormalities have clinical manifestations of skin, joint, or skeletal abnormalities of a defined heritable connective tissue disorder. In specimens of arterial walls of carotid, aortic, and renal arteries of patients with sCAD, pronounced systemic, histopathological, and

    A 7-year-old male castrated domestic short-haired cat suddenly died. Gross examination revealed severe right-sided haemothorax with blood clots, four adult filarial nematodes in the blood clots and the caudal vena cava and haemorrhage dissecting into the tunica media of the right pulmonary artery. Histopathological investigation showed fibrosis of the tunica intima and disorganization/fragmentation of the elastic fibres accompanied by fibrous tissue deposition in the tunica media of both branches of pulmonary artery. Degenerative vasculopathy (intimal fibromuscular hyperplasia and medial hypertrophy/hyperplasia) involving pulmonary arteries was also observed. The polymerase chain reaction amplification and sequencing confirmed the identification of the parasite as Dirofilaria immitis. A diagnosis of pulmonary artery dissection with haemothorax and concomitant heartworm disease was formulated. Degenerative processes of the tunica media have been reported to cause pulmonary artery dissection in both humans and animals. Pulmonary artery remodelling induced by heartworms may be considered the underlying cause in the first case of feline pulmonary artery dissection, herein described.

    Full Text Available We present a case of a 34-year-old male who presented to the emergency ward with fever and abdominal pain. The diagnosis of Takayasu’s arteritis and also antiphospholipid syndrome was made during an imaging workup of deep-vein thrombosis. A spontaneous coronary artery dissection was revealed in coronary CT angiography requested for chest pain and dyspnea. The patient was treated medically and discharged on close followup. The concurrence of spontaneous coronary artery dissection with antiphospholipid syndrome and Takayasu’s arteritis has not been reported in the previous literature. The possibility of a spontaneous coronary artery dissection should be considered in patients presenting with both diseases.

    Full Text Available Partial oculosympathetic palsy followed by ischemic manifestations in brain or retina are the main symptoms of extracranial internal carotid artery (ICA dissection. Unusually, cranial nerves may be affected. Isolated oculomotor nerve palsy is found only rarely. CASE: We present a 50-year-old nondiabetic man who experienced acute onset of right occipital headache which spread to the right retro-orbital region. Five days later he noticed diplopia and right blurred vision sensation. Neurologic examination disclosed only impaired adduction and upward gaze of right eye, slight ipsilateral pupillary dilatation, without ptosis. Brain MRI was normal. Angiography showed right internal carotid artery dissection with forward occlusion to the base of the skull. Intravenous heparin followed by warfarin was prescribed. The headache and the oculomotor nerve deficit gradually resolved in the next three weeks. DISCUSSION: Isolated oculomotor nerve palsy is underrecognized as a clinical presentation of extracranial ICA dissection. If the angiographic evaluation is incomplete without careful study of extracranial arteries, misdiagnosis may lead to failure to initiate early treatment to prevent thromboembolic complications. For this reason we draw attention to the need for careful evaluation of cervical arteries in patients with oculomotor nerve palsy. Mechanical compression or stretching of the third nerve are possible mechanisms, but the direct impairment of the blood supply to the third nerve seems to be the most plausible explanation.A paralisia oculosimpática parcial (síndrome de Horner seguida por manifestações isquêmicas cerebrais ou retinianas são os principais sintomas da dissecção da artéria carótida interna (ACI extracraniana. O acometimento de nervos cranianos é incomum. Apenas raramente a paralisia isolada do nervo oculomotor pode ser encontrada.

    Full Text Available Extra-cranial arterial dissection accounts for 10% of strokes in young people. Information on safety of thrombolytic administration in this group is limited. The literature, however, does not favor use of thrombolytics for myocardial ischemia when peripheral arterial dissection coexists. Based on the clinical and radiological features, two patients who presented with acute stroke secondary to arterial dissection were considered for thrombolysis. One of them received intra-venous recombinant tissue plasminogen activator (rtPA, and the other patient received intra-arterial rtPA. There were no post thrombolysis complications. This report supports feasibility of administering thrombolytics in acute ischemic strokes resulting from extra-cranial arterial dissection. Future larger studies are necessary to determine the efficacy, safety and long-term outcome in this patient population.Dissecção arterial cérvico-cefálica corresponde a 10 % dos acidentes vasculares cerebrais (AVC em jovens. Informação sobre a segurança da administração de trombolíticos neste grupo é limitada. A literatura médica, entretanto, não favorece o uso de trombolíticos em isquemia miocárdica na coexistência de dissecção arterial periférica. Baseado nas características clínicas e radiológicas, dois pacientes com AVC agudo secundário a dissecção arterial foram considerados para terapia trombolítica. Um deles recebeu rtPA intravenoso e o outro paciente recebeu rtPA intra-arterial. Não houve complicações pós-trombólise. Este relato suporta a possibilidade do tratamento destes pacientes com terapia trombolítica. Estudos maiores são necessários para determinar a eficácia, segurança e resultados a longo prazo nesta população de pacientes.

    Ehlers-Danlos syndrome (EDS) is a rare heterogeneous group of connective tissue disorders. The vascular type (vEDS) is an autosomal dominant disorder caused by heterozygous mutations in the COL3A1 gene predisposing to premature arterial, intestinal, or uterine rupture. We report a case of a 38-year-old woman with a recent diagnosis of vEDS admitted in the Emergency Department with a suspicion of a pyelonephritis that evolved to a cardiopulmonary arrest. A fatal retroperitoneal hematoma related with a haemorrhagic dissection of the right renal artery was found after emergency surgery. This case highlights the need to be aware of the particular characteristics of vEDS, such as a severe vascular complication that can lead to a fatal outcome. PMID:26175915

    Spinal injury following inertial loading of the head and neck (whiplash) is a common sequel of low speed traffic crashes. A variety of non-musculoskeletal injuries have been described in association with injury to the spine following whiplash trauma, including traumatic brain injury, vestibular derangement, and cranial nerve injury, among others. Vascular injuries in the head and neck have, however, only rarely been described. We present the case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery (ICA) and intracerebral vascular structures following a hard braking maneuver, with no direct head- or neck contact with the vehicular interior. Based on this unusual mechanism of injury we reviewed hospital data from the United States nationwide inpatient database (NIS) to assess the frequency of similar injuries reportedly resulting from traffic crashes. The post-mortem examination revealed a left internal carotid artery dissection associated with subarachnoid hemorrhage (SAH). Based on the close temporal association, the absent prior history, and the plausibility of the injury mechanism, the injury was attributed to the braking maneuver. An analysis of NIS data demonstrated that the prevalence of subarachnoid hemorrhage is significantly higher when there is a traumatic etiology, and higher yet when the trauma is a traffic crash (odds ratio 3.3 and 4.3, respectively). The presented case, together with the hospital inpatient data analysis, indicate that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash. In a clinical or forensic setting the inference that magnitude of a trauma was low should not serve as a basis for either excluding a cervical artery dissection from a differential diagnosis, or for excluding the trauma as a cause of a diagnosed dissection. This case report illustrates a rare fatal outcome of inertial load to

    Mortality rates associated with acute type B aortic dissection (ABAD) complicated by malperfusion remains significant. Optimal management of patients with ABAD is still debatable. We present a case report of a 50-year-old man who was admitted due to ABAD. He was treated medically with his pain resolved and he was discharged on oral antihypertensive medications. One month after initial diagnosis, he was readmitted with abdominal pain, nausea, vomiting, and diarrhea. On imaging, an extension of the aortic dissection into the visceral arteries with occlusion of the celiac and superior mesenteric arteries (SMA) was noted. He underwent thoracic endovascular aortic repair (TEVAR) and bypass grafting to the SMA. Despite the intervention, the patient developed large bowel, liver, and gastric ischemia and underwent bowel resection. He died from multi-organ failure. In selected cases of uncomplicated ABAD, TEVAR should be considered and when TEVAR fails and visceral malperfusion develops, an aggressive revascularization of multiple visceral arteries should be attempted.

    Full Text Available Abstract The arterial cannulation site for optimal tissue perfusion and cerebral protection during cardiopulmonary bypass (CPB for surgical treatment of acute type A aortic dissection remains controversial. Right axillary artery cannulation confers significant advantages, because it provides antegrade arterial perfusion during cardiopulmonary bypass, and allows continuous antegrade cerebral perfusion during hypothermic circulatory arrest, thereby minimizing global cerebral ischemia. However, right axillary artery cannulation has been associated with serious complications, including problems with systemic perfusion during cardiopulmonary bypass, problems with postoperative patency of the artery due to stenosis, thrombosis or dissection, and brachial plexus injury. We herein present the case of a 36-year-old Caucasian man with known Marfan syndrome and acute type A aortic dissection, who had direct right axillary artery cannulation for surgery of the ascending aorta. Postoperatively, the patient developed an axillary perigraft seroma. As this complication has, not, to our knowledge, been reported before in cardiothoracic surgery, we describe this unusual complication and discuss conservative and surgical treatment options.

    We report a case of a 63-year-old man, with a previous history of hypertension and glucose intolerance associated troncular obesity that was emergently admitted to our Institution for evaluation of a severe, constant posterior chest pain which radiated anteriorly and dyspnoea with a suspected diagnosis of acute aortic dissection. A CT scan of thorax and abdomen demonstrated a dissection starting just below left succlavian artery and extending downward to the left renal artery, involving the celiac tripod and superior mesenteric artery. The dissection was classified as Stanford B, De Bakey III. Moreover, CT scan of abdomen revealed incidentally a left adrenal tumor of 25 mm of diameter. An emergent prosthetic graft was placed just below the origin of the left succlavian artery up-to the diaphragmatic hiatus. Furthermore, a diagnostic evaluation of the mass revealed an increase of cortisol production, and a diagnosis of Cushing's syndrome was done and the patient underwent an adrenalectomy via laparotomic approach. We report an association of acute aortic dissection of acute aortic dissection type B associated to Cushing's syndrome.

    2013-06-01

    Full Text Available Ehlers-Danlos syndrome (EDS type IV, also known as vascular EDS, is an inherited connective tissue disorder with an estimated prevalence of 1/100,000 to 1/250,000. In EDS type IV, vascular complications may affect all anatomical areas, with a preference for large- and medium-sized arteries. Dissections of the vertebral and carotid arteries in their extra- and intra-cranial segments are typical. The authors report the case of a patient with EDS type IV for whom the diagnosis was established based on clinical signs and who developed internal carotid artery dissection at the age of 44 years. In the absence of a specific treatment for EDS type IV, medical interventions should focus on symptomatic relief, prophylactic measures, and genetic counseling. Invasive imaging techniques are contraindicated, and a conservative approach to vascular complications is usually recommended.

    We evaluated the indications of operation and radiologic findings in 12 operated DeBakey type III aortic dissections. We retrospectively reviewed radiologic findings of 12 operated DeBakey type III aortic dissections, using CT, MRI, or aortography, and correlations were made with clinical course of the patients. Three cases were uncomplicated dissections. There were aneurysm rupture in 4 cases, impending rupture in 4 cases, occlusion of common iliac artery in 2 cases, occlusion of renal artery in 1 case, and compression of bronchus and esophagus by dilated aorta in 1 case. Associated clinical sign and symptoms were chest and back pain in 12 cases, claudication in 3 cases, dyspnea and dysphagia in 1 case, hoarseness in 1 case, and hemoptysis in 1 case. Post-operative complications were death from aneurysm rupture in 1 case, paraplegia in 2 cases, acute renal failure in 3 cases, and hemopericardium in 1 case. Although medical therapy is preferred in management of DeBakey type III aortic dissection, surgical treatment should be considered in patients with radiological findings of aortic rupture, impending rupture, occlusion of aortic major branches.

    Full Text Available A number of hepatic artery variations exists which is continuously proving a hindrance for the surgeons and radiologists. During routine dissection in the subhepatic region in 50 year old male cadaver for undergraduate teaching, a variation in the branching pattern of common hepatic artery was noticed. We observed an unusual branching of the common hepatic artery into seven terminal branches, of which two were left hepatic arteries, two were right gastric arteries and the remaining three were right hepatic artery, cystic artery and gastroduodenal artery. Hepatic artery proper was absent. Embryological basis of these variations were discussed. The present case is a rarity and will further throw light on the knowledge of the hepatic artery variations, thus assisting surgeons and radiologists in various surgical and diagnostic procedures.

    Acute myocardial infarction with spontaneous coronary dissection was fatal in a 33-years-old man. Autopsy and family history revealed type IV Ehlers-Danlos syndrome. In this disease, conjunctive tissue is fragilized due to a deficit in type III collagen which leads to spontaneous ruptures in large and medium sized arteries. The present case is the first with a proven rupture of the coronary arteries. This disease should be entertained in young people with no atherogenous risk factor and an acute coronary disorder since peripheral skin and joint syndromes may be discreet or missing. Treatment is difficult in case of spontaneous coronary dissection. Thrombolysis is not possible and diagnosis may require angiography which is in itself dangerous due to the fragility of the coronary vessels.

    We report a 41-year-old woman with embolic stroke of the mid-pons attributed to embolism from vertebral artery dissection. Angiography revealed an occluded artery on one side and an incidental pseudoaneurysm of the midcervical portion of the vertebral artery on the other. After 3 months of warfarin therapy control angiography showed complete occlusion of the pseudoaneurysm. We discuss therapeutic choices and review the literature. (orig.) With 4 figs., 8 refs.

  5. Resolution of Internal Carotid Dissection with Middle Cerebral Artery Occlusion in Pregnancy

    Full Text Available Introduction. Cervical artery dissection (CAD is a common cause of stroke in younger patients. While the incidence of stroke in pregnancy is increasing, CAD remains a rare cause of ischemic stroke in the pregnant population, with only 30 cases described in the literature, most in the postpartum period. Methods. The case of a pregnant patient at 18 weeks of gestation presenting with CAD and ischemic stroke following intercourse is discussed. Discussion. CAD results from an intimal tear in the carotid artery, allowing accumulation of blood in the vessel wall. Stroke results from embolization of thrombogenic material in the wall. Etiology includes minor trauma, connective tissue disorders, or anatomic variations of the carotid artery. Most patients present with headache and/or neck pain, while ischemic symptoms are seen in at least 50% of patients. In the pregnant population, imaging with MRI or MRA of the head and neck aids in diagnosis. Once the diagnosis is made, patients are treated with either anticoagulation or antiplatelet medications. The optimal treatment in both pregnant and nonpregnant patients has not been well-studied. Conclusion. CAD is an important diagnosis to consider in a pregnant patient with persistent headache, especially if neurological symptoms are present. Imaging should be quickly obtained so treatment can be initiated.

    Intracranial aneurysms in the paediatric population are uncommon, accounting for 2% to 6% of all aneurysms, and spontaneous arterial dissection is rarely reported as the cause of aneurysms in children, especially in the posterior cerebral artery. Two cases of paediatric spontaneous posterior cerebral artery dissecting aneurysms are reported, one in a 33-month-old male child presenting with aneurysmal rupture and subarachnoid haemorrhage and the other in a 9-year-old boy with an unruptured aneurysm. The first child was successfully treated by endovascular parent vessel occlusion without neurological deficit and in the second a spontaneous thrombosis of the aneurysm and its parent artery occurred associated with hydrocephalus and a favourable outcome. Dissecting aneurysms are dynamic lesions with variable and unpredictable evolution and close follow-up and/or early treatment is warranted. Spontaneous arterial dissection is a rare, probably still under-recognized, cause of intracranial aneurysms that may be responsible for a significant number of aneurysms and spontaneous aneurysmal thromboses in children.

    Full Text Available Carotid artery dissections are one of the important reasons of cerebrovascular events that are observed before the age of 45. Besides the local findings such as head, neck and face pains, Horner syndrome findings, pulsatile tinnitus and cranial nerve involvements, some other symptoms such as ischemic stroke, transient ischemic attacks and amaurosis fugax can also be observed in the approximately three quarters of patients. Ischemic optic neuropathy may be seen as %4 in the carotid artery dissections and it mostly accompanies other ischemic local symptoms. It is rare to observe the ischemic optic neuropathy as the first and unique finding in the carotid artery dissections. In this study, a 55 year old male patient with carotid artery dissection was represented. He did not have any other complaint, except the sudden unilateral visual loss and he was sent to our clinics from the opthalmology clinics in order to search for the etiology of ischemic optic neuropathy. It should be kept in mind that there can be a possibility to have carotid artery dissections in patients with unilateral visual loss.

  8. Delayed presentation of carotid artery dissection following major orthopaedic trauma resulting in dense hemiparesis.

    We report a 30-year-old patient who was involved in a high-velocity road traffic accident and developed a left-sided hemiparesis, which was noted in the post-operative period following bilateral femoral intramedullary nailing. CT scanning of the brain revealed infarcts in the right frontal and parietal lobes in the distribution of the right middle cerebral artery. CT angiography showed occlusion of the right internal carotid artery consistent with internal carotid artery dissection. He was anticoagulated and nine months later was able to walk independently. An awareness of this injury is needed to diagnose blunt trauma to the internal carotid artery. Even in the absence of obvious neck trauma, carotid artery dissection should be suspected in patients with a neurological deficit in the peri-operative period.

    Between January 1, 1992 and December 31, 1996, a total of 1095 head trauma vicims were admitted in our intensive care unit. If CT scans demonstrated ischemic brain lesions, arteriography to visualize supraaortic vessels was performed. Carotid artery dissection was observed in ten patients (0.91%) and was bilateral in eight patients (0.73%). In the bilateral carotid artery dissection (BCAD) group, there were five women and three men, with a mean age of 35.2 years (range: 17 to 54 years). Injuries resulted from traffic accidents in seven patients and a fall in one patient. Upon admission, six patients presented with alteration of consciousness and three with hemiplegia or hemiparesia, associated with aphasia in two cases. In two other cases, hemiplegia occurred 24 hr and 13 days after the accident. All patients had brain infarction, which was unilateral in five cases and bilateral in three cases. The severity of lesions was graded on the basis of arteriographic findings as follows: Type I, wall involvement without significant stenosis or dilation; Type II, arterial dissection with stenosis >70% (Type IIA) or dilatation >50% (Type IIB) and the normal diameter of the proximal or distal internal carotid artery; and Type III, thrombosis of the internal carotid artery. Lesions were asymmetrical in six patients, including two with Type II and III lesions and four with Type I and II lesions, and symmetrical in two patients, including one with bilateral Type III lesions and one with bilateral Type II lesions. Surgery was performed in two patients with Type II lesions, including one case associated with contralateral carotid thrombosis. The intrapetrous carotid artery was exposed by an ear-nose-throat (ENT) surgeon and repaired by interposition grafting. Follow-up in these two surgical cases was 28 and 31 months. In the remaining six cases, medical treatment was performed. Outcome in nonsurgical cases was variable: death in two cases at 31 and 43 days after the accident

    A 7-month-old baby presented with a 4-day history of drowsiness and vomiting after a falling accident. Magnetic resonance imaging demonstrated diffuse subarachnoid hemorrhage, intraventricular hemorrhage, and variable stages of subdural hematoma in bilateral occipital and left temporal subdural spaces. A partially thrombosed aneurysm was noted in the right craniocervical junction. Ophthalmological examination revealed bilateral retinal petechial hemorrhages. Conventional cerebral angiography revealed a dissecting aneurysm in the right posterior inferior cerebellar artery (PICA). Endovascular embolization was suggested, but the family refused. After conservative treatment, follow-up MRI revealed that the PICA aneurysm had remodeled and ultimately disappeared completely at the 10th month. This case illustrates the relatively plastic nature of intracranial aneurysms in pediatric patients. More studies are necessary to clarify the natural history of spontaneously thrombosed aneurysms to assist in their overall management.

    Aberrant left-sided pulmonary artery(pulmonary artery sling) is an uncommon anomaly,which may cause significant respiratory abnormality. We report a case of pulmonary artery sling which is combined with persistent left superior vena cava and dextrocardia. This case were identified by esophagogram and CT and confirmed by MRI and angiography. We consider that MRI is a valuable new method for the diagnosis of aberrant left-sided pulmonary artery.

    Aortic dissection is a critical but rare complication of Turner syndrome. This report describes a case of chronic aortic dissection in a patient with Turner syndrome. A 54-year-old woman, suffering from mild back pain for 1 month, was referred to our hospital with a diagnosis of Stanford type A chronic aortic dissection and a bicuspid aortic valve with moderate regurgitation. Computed tomography revealed aortic dissection, involving all arch branches, extending from the ascending to the abdominal aorta. The true lumen of the brachial artery was nearly obstructed by the thrombosed false lumen. Elective aortic arch repair and aortic valve replacement were successfully performed. The patient was diagnosed with 45, XO Turner syndrome after surgery. Taking aortopathy of Turner syndrome into consideration, surveillance of the residual aorta was performed. No rapidly progressive dilatation of the residual aorta was detected during the 6 years' follow-up.

    Flow diverters constitute a new generation of flexible self-expanding stent-like devices with a high metal-surface area coverage, specifically designed for the endovascular management of complex cerebral aneurysms. Recently, other potential applications for these devices in the field of occlusive cerebrovascular disease have been described. In vertebral artery dissections causing occlusion associated with a burden of extensive clots, we have found that the reduced porosity of the diverter mesh serves as an effective barrier to in-stent clot protrusion and distal embolization. We describe the novel use of a flow diverter for the management of an occlusive traumatic vertebral artery dissection. Diverter implantation allowed subsequent angioplasty.

    The main reasons of emergent conversion during thoracoscopic lobectomy included tumor invasion, hilar lymph node (LN) metastasis, and lymphoid tuberculosis. We presented a video which depicted a three-portal thoracoscopic left upper lobectomy with dissection of large LNs. Severe adhesions between a large LN and the first branch of the left pulmonary artery (PA) were found during surgery. For safety reasons, the left main pulmonary artery (LMPA) was clamped with an endoscopic bulldog clamp prior to lymph nodal dissection. The strategy of precontrolling the LMPA during thoracoscopic lobectomy is useful for these patients with complicated hilum, and may assure the safety of the operation. PMID:27162690

    Spontaneous coronary artery dissection (SCAD) is an extremely uncommon condition that can lead to fatal acute myocardial infarction. There have been very few case reports of SCAD in patients with systemic lupus erythematosus (SLE) and even fewer in association with antiphospholipid antibodies - mainly postpartum. This is the first reported case of SCAD in a patient who was confirmed to have SLE and tested positive for anticardiolipin antibody and lupus anticoagulant. This case demonstrates the importance of carefully considering the differential diagnoses of SCAD at presentation. It also highlights the need for further research to explore the link between SLE, antiphospholipid antibodies and SCAD.

    Highlights: • The use of a color scale to display the non-contrast CT images in lieu of the classic grayscale improves the diagnostic confidence of the readers. • Radiologists should consider the use of a color scale, rather than the conventional grayscale, to assess non-contrast CT studies for possible carotid artery dissection. - Abstract: Purpose: The purpose of this work was to evaluate if the use of color maps, instead of conventional grayscale images, would improve the observer's diagnostic confidence in the non-contrast CT evaluation of internal carotid artery dissection (ICAD). Materials and methods: One hundred patients (61 men, 39 women; mean age, 51 years; range, 25–78 years), 40 with and 60 without ICAD, underwent non-contrast CT and were included in this the retrospective study. In this study, three groups of patients were considered: patients with MR confirmation of ICAD, n = 40; patients with MR confirmation of ICAD absence, n = 20; patients who underwent CT of the carotid arteries because of atherosclerotic disease, n = 40. Four blinded observers with different levels of expertise (expert, intermediate A, intermediate B and trainee) analyzed the non-contrast CT datasets using a cross model (one case grayscale and the following case using the color scale). The presence of ICAD was scored on a 5-point scale in order to assess the observer's diagnostic confidence. After 3 months the four observers evaluated the same datasets by using the same cross-model for the alternate readings (one case color scale and the following case using the grayscale). Statistical analysis included receiver operating characteristics (ROC) curve analysis, the Cohen weighted test and sensitivity, specificity, PPV, NPV, accuracy, LR+ and LR−. Results: The ROC curve analysis showed that, for all observers, the use of color scale resulted in an improved diagnostic confidence with AUC values increasing from 0.896 to 0.936, 0.823 to 0.849, 0.84 to 0.909 and 0

    Full Text Available Ischemic stroke due to carotid artery dissection is more common among young people and it accounts about 2-5% of all strokes. A 56 year old left landed male patient was evaluated for left-sided hemiparesis and aphasia in the emergency department. His cranial CT was assessed normal and NIH score was assessed 24 then he undergone thrombolytic therapy. His NIH score was decreased to 14 after 24 hours. At extracranial dupplex USG, cranial MRI and MR-Angiography, done the same day there were findings for carotid dissection. At MR-anjio repeated 5 days later, partial recanalization were seen. At control cranial CT only striocapsüler infarct was seen. There was no any evidence of bleeding as complication. Here we present a rare case of extracranial carotid artery dissection case undergone IV thrombolytic therapy and want to take attention that in carotid dissection IV thrombolytic therapy is quiet safe and there is no difference of complication such as hemorrhage and the prognosis is no different then those with no carotid dissection.

    PurposeThe treatment of ruptured vertebral artery dissecting aneurysms (VADAs) continues to be controversial. Our goal was to evaluate the safety, efficacy, and long-term outcomes of internal trapping and stent-assisted coiling (SAC) for ruptured VADAs distal to the posterior inferior cerebellar artery (supra-PICA VADAs), which is the most common subset.MethodsA retrospective review was conducted of 39 consecutive ruptured supra-PICA VADAs treated with internal trapping (n = 20) or with SAC (n = 19) at our institution. The clinical and angiographic data were retrospectively compared.ResultsThe immediate total occlusion rate of the VADAs was 80 % in the trapping group, which improved to 88.9 % at the follow-ups (45 months on average). Unwanted occlusions of the posterior inferior cerebellar artery (PICA) were detected in three trapped cases. Incomplete obliteration of the VADA or unwanted occlusions of the PICA were detected primarily in the VADAs closest to the PICA. In the stenting group, the immediate total occlusion rate was 47.4 %, which improved to 100 % at the follow-ups (39 months on average). The immediate total occlusion rate of the VADAs was higher in the trapping group (p < 0.05), but the later total occlusion was slightly higher in the stenting group (p > 0.05).ConclusionsOur preliminary results showed that internal trapping and stent-assisted coiling are both technically feasible for treating ruptured supra-PICA VADAs. Although not statistically significant, procedural related complications occurred more frequently in the trapping group. When the VADAs are close to the PICA, we suggest that the lesions should be treated using SAC.

    2015-10-01

    Full Text Available This case report describes a patient found to have amaurosis fugax as a result of non-traumatic internal carotid dissection. Monocular blindness can be due to multiple causes including keratitis, acute glaucoma, vitreous hemorrhage, uveitis, retinal vascular occlusion, retinal detachment, optic neuropathy, trauma, or vascular malformations. In the setting of headache, neck pain, and an otherwise normal ophthalmic examination, this case report highlights the importance of recognizing transient ischemic attack and carotid artery dissection in the differential diagnosis. To further clarify the diagnosis, carotid ultrasound may aid diagnosis as was seen in this case, where decreased internal carotid artery velocities were found and subsequent CT angiography of the neck confirmed a diagnosis of carotid dissection. If a dissection is present, progression of symptoms may indicate impending cerebral infarction and warrant immediate attention. Antiplatelet therapy is the first-line treatment with anticoagulation, thrombolysis, and surgery reserved for cases of recurrent, progressive symptomatic episodes. Surgical options include endovascular repair such as angioplasty, stent placement, embolization, surgical revascularization, and bypass.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome that has been associated with peripartum and postpartum periods. It results from the separation of the layers of the arterial wall of the coronary artery with the subsequent formation of a false lumen. We report a case of a 54-year-old female who presented to the cruise ship's medical facility complaining of epigastralgia and dizziness. Work up including an electrocardiography and cardiac profile was ordered. Results yielded a diagnosis of non-ST segment elevation myocardial infarction (NSTEMI). Treatment following American Heart Association recommendations including nitrates, clopidogrel and enoxaparin was given. After debarkation at sea and referral to a reference hospital, the patient was diagnosed with SCAD. Patient's outcome was favorable and she was discharged home a few days after, despite being managed as a NSTEMI.

    Full Text Available A thematic block is taught in the Veterinary Medicine Program at La Salle University’s Faculty of Agricultural Sciences that is relevant to the basic disciplinary training of future veterinarians. It is the theoretical and practical subject of the anatomy of the head of domestic species, which includes the head of horses. The study is addressed by testing the theory in the exercise of a dissection, and the exploration of the different structures that make up the head. This regional and systematic study includes angiology of the head, where emphasis is made on the branches of the common carotid artery as main vessel that irrigates the head. The common carotid artery ends in the occipital, internal carotid and external carotid arteries; the last one splits into two main terminal branches, namely: the internal maxillary artery and the superficial temporal. Generally, the internal maxillary artery follows a path that is repeated in almost all specimens that are dissected as described by different authors; however, in some cases there may variations in the path of the artery, such as in its branches. The purpose of this work is to inform about a case that arose in a regular class in the anatomy lab during dissection of a horse head where arteries were being studied macroscopically. Dissection showed a variation in the normal path of the internal maxillary artery at the level of lateral pterygoid muscle. The case involves an 11-year old mare that was put down by unqualified personnel outside the campus, and whose head was later severed and sent to the gross anatomy labs of the Veterinary Medicine program at the Faculty of Agricultural Sciences. Given its provenance, it was not possible to know the anamnesis, nor the history of the animal.

    We describe the pathologic features of mural arterial dissection involving brain-supplying arteries in a 31-y-old female chimpanzee (Pan troglodytes). Several hours after examination for a possible respiratory tract infection, the chimpanzee became unresponsive, developed seizures, and died within 18 h. At necropsy, the occipital cortex of the brain had a small area of congestion, and the cerebellar cortex contained a small necrotic area. Histologic evaluation confirmed the cortical lesions and revealed an additional necrotic area in the medulla oblongata characterized by mural dissection of the brain-supplying vertebral and basilar arteries and subsequent branches. Lesions in the cortices and medulla were within areas supplied by the vertebrobasilar system. Dissection of brain-supplying arteries has been described in humans but not previously in chimpanzees (or any other NHP), suggesting that these species might be useful in understanding this condition in humans. In addition, the lesion should be added to the NHP clinician's and pathologist's differential diagnosis list for similar presentations in this species.

    2012-09-01

    Full Text Available Abstract Background Craniocervical arterial dissection is a major cause of ischaemic stroke in young adults. The pathogenesis is not fully understood but is thought to be related to a combination of an intrinsic weakness in the arterial wall and an external trigger. Intrinsic susceptibility is thought to be a generalised arteriopathy, vascular anomaly or genetic predisposition. Proposed extrinsic factors include recent viral infection and minor mechanical trauma to the neck, including neck manipulation, which has raised concerns amongst manual practitioners in particular as to the appropriate screening of patients and avoidance of more vigorous therapeutic techniques. The presenting features of dissection may mimic a musculoskeletal presentation, creating a diagnostic dilemma for primary care practitioners. Early recognition is critical so that appropriate management can be commenced. The aims of this study are to prospectively investigate young patients ≤55 years admitted to hospital with radiologically diagnosed craniocervical arterial dissection compared to matched controls with stroke but not dissection, to identify risk factors and early presenting clinical features, so these may be more readily identified by primary care practitioners. Methods Patients ≤ 55 years presenting to hospital with craniocervical arterial dissection and controls will have their medical records reviewed and be interviewed and questioned about possible risk factors, preceding events to admission such as recent neck trauma, and presenting clinical features including any preceding transient ischaemic features. Clinical assessment will include a connective tissue screening examination to identify subclinical connective tissue disorders. Radiology and blood screening will be reviewed for typical features and inflammatory markers. Functional outcome will be reviewed to determine the burden of the stroke. Discussion This study will provide descriptive and

  6. Cocaine mediated apoptosis of vascular cells as a mechanism for carotid artery dissection leading to ischemic stroke.

    In arterial dissection, blood may enter the arterial wall through an intimal tear, splitting the arterial wall and activating the coagulation cascade at the site of endothelial damage. Dissection of extracranial and intracranial vessels may lead to ischemic stroke through thromboembolic or hemodynamic mechanisms. Major blunt trauma or rapid acceleration-deceleration may cause dissection, but in patients with inherent arterial wall weakness, dissection can occur spontaneously or as a result of minor neck movement. Cocaine use has been associated with dissection of the aortic arch and coronary and renal arteries through cocaine-mediated hypertension. Recent preclinical studies have suggested, however, that cocaine may cause apoptosis of cells in the vascular wall. In this article, we postulate that cocaine may cause apoptosis of vascular endothelial and/or smooth muscle cells, thus weakening the vascular wall and resulting in a dissection-prone state. We review the literature and propose a biological basis for vasculopathy, vascular dissection, and ischemic stroke in the setting of cocaine use. Further research studies on vascular cells, as well as focused analysis of human pathological material, will be important in providing evidence for or against our hypotheses.

  7. A case report: accessory right renal artery

    2009-10-01

    Full Text Available Anatomical variations in the origin of the arteries in the abdominal area are very common. The arteries that show frequent variations include the celiac trunk, renal and gonadal arteries. During a routine dissection of a male cadaver, one main and one inferior accessory renal artery were found in the abdominal region. We discovered that the inferior accessory renal artery that originated from the right anterolateral aspect of abdominal aorta was running into the lower pole of the right kidney. The origin of the main right renal artery and the inferior accessory right renal artery were 19.8 mm and 53 mm below the superior mesenteric artery, respectively. The inferior accessory right renal artery ran directly into the inferior pole of the right kidney, in the area where the accessory right renal vein was leaving the right kidney. These anatomical variations and anomalies are important to know before any therapeutic or diagnostic procedures are performed in the abdominal area.

Case presentation During routine cadaveric dissection of a 69-year-old fresh female cadaver, a superficial brachioulnar artery with an aberrant path was found bilaterally. The superficial brachioulnar artery originated at midarm level from the brachial artery, pierced the brachial fascia immediately proximal to the elb...

    We report the case of a patient with completely painless chronic aortic dissection, who presented to another hospital with a left hemiparesia 3 months ago and received anticoagulation therapy with a diagnosis of ischemic stroke. Most of her symptoms had resolved when she presented to our outpatient clinic except for numbness of her left hand and dysphasia. Physical examination found a diastolic murmur at the left sternal border and a bruit over the right carotid artery. Transthoracic echocardiography and carotid sonography demonstrated aortic dissection with extension into the internal right carotid artery and severe aortic regurgitation. Surgery was performed successfully and the patient was discharged. This case emphasizes that the diagnosis of a completely painless aortic dissection with only neurologic symptoms at presentation can be extremely difficult and should always be considered as a cause of ischemic stroke to avoid catastrophic antithrombolytic or anticoagulation therapy.

    Background The goal of this study was to compare early postoperative outcomes and actuarial-free survival between patients who underwent repair of acute Type A aortic dissection with axillary or femoral artery cannulation. Methods A total of 305 patients from five academic medical centers underwent acute Type A aortic dissection repair via axillary (n = 107) or femoral (n = 198) artery cannulation between January 2000 and December 2010. Major morbidity, operative mortality, and 5-year actuarial survival were compared between groups. Multivariate logistic regression was used to determine predictors of operative mortality, and Cox regression hazard ratios were calculated to determine predictors of long-term mortality. Results Operative mortality was not influenced by cannulation site (16% for axillary cannulation vs. 19% for femoral cannulation, p = 0.64). In multivariate logistic regression analysis, hemodynamic instability (p 200 min; p = 0.05) emerged as independent predictors of operative mortality. Stroke rates were comparable between the two techniques (14% for axillary and 17% for femoral cannulation, p = 0.52). Five-year actuarial survival was comparable between the groups (55.1% for axillary and 65.7% for femoral cannulation, p = 0.36). In Cox regression analysis, predictors of long-term mortality were: age (p < 0.001), stroke (p < 0.001), prolonged cardiopulmonary bypass time (p = 0.001), hemodynamic instability (p = 0.002), and renal failure (p = 0.001). Conclusions The outcomes of femoral versus axillary arterial cannulation in patients with acute Type A aortic dissection are comparable. The choice of arterial cannulation site should be individualized based on different patient risk profiles. PMID:28097193

    Background and Purpose. Spontaneous vertebral artery dissection (SVAD) is an important reason for posterior-circulation-ischemic stroke in the young and middle-aged population. Although some previous reports reveal a favorable outcome with conservative therapy, it is still controversial in the treatment of SVAD in some specific patients. Herein, we present our 10 years of clinical experience for SVAD at this location. Material and Methods. 20 patients with 20 SVADs in V2 and V3 segments were retrospectively studied. Clinical manifestations and imageology materials were collected and analyzed. All the patients underwent anticoagulation except for one patient because of contraindication. 14 patients underwent Wingspan stents implantation with general anesthesia. Results. In our sample, ischemia (infarction or transient ischemic attack, TIA) was found in all the patients. Angiographic stenosis and dissection aneurysm were the most common findings in the segments mentioned above. 19 of the patients (95%) got the excellent imageological and clinical outcomes. Conclusions. According to our experience in this group, although anticoagulation is effective in vertebral artery dissection, interventional therapy for SVADs in V2 and/or V3 segments is preferred in some specific patients. Stent with higher radial supporting and flexibility, such as Wingspan stent, is suggested.

Patients and methods: A female patient with THS affecting the left eye was examined using two magnetic resonance imaging (MRI scans. The patient was treated with high-dose methylprednisolone (Solu-Medrol® and prednisone. A follow-up MRI and magnetic resonance angiogram (MRA was also performed 4 months later. Results: The second MRI scan disclosed a 5x9x10 mm lesion in the left superior orbital fissure/cavernous sinus. After administration of methylprednisolone and prednisone, the patient’s pain completely resolved, and the left eye regained full duction and eyelid mobility. The MRI and MRA obtained after the treatment showed no abnormalities. Conclusion: The rarity of THS makes it difficult to diagnose, especially when there is a question of accuracy and reproducibility of the testing performed. An ophthalmologic consultation in such cases is crucial. Keywords: granulomatous lesion, painful ophthalmoplegia, idiopathic orbital inflammation, multiple cranial nerve palsies

    Full Text Available Abstract Cotyledonoid dissecting leiomyoma of the uterus is a recently described rare variant of benign uterine leiomyoma. We report a case of cotyledonoid dissecting leiomyoma in a 52 year old woman who presented with menorrhagia and abdominal pain. An ultrasound scan showed a bulky uterus and a cystic heterogenous mass near the left ovary. At hysterectomy, the left broad ligament mass was removed. This was continuous with an ill-defined nodular area in the myometrial fundus. Microscopy revealed a benign smooth muscle proliferation in the myometrium that extended beyond the uterus and into the broad ligament. The lesion appeared to be dissecting the myometrial fibres and showed areas of oedema, hyalinisation and perinodular hydropic change. Cellular atypia, mitoses and coagulative necrosis were absent. The patient is alive and well 18 months after surgery. It is important to recognize this benign and unusual appearing variant of leiomyoma in order to prevent inappropriate treatment.

    Full Text Available OBJECTIVE: To compare the effects of antiplatelets and anticoagulants on stroke and death in patients with acute cervical artery dissection. DESIGN: Systematic review with Bayesian meta-analysis. DATA SOURCES: The reviewers searched MEDLINE and EMBASE from inception to November 2012, checked reference lists, and contacted authors. STUDY SELECTION: Studies were eligible if they were randomised, quasi-randomised or observational comparisons of antiplatelets and anticoagulants in patients with cervical artery dissection. DATA EXTRACTION: Data were extracted by one reviewer and checked by another. Bayesian techniques were used to appropriately account for studies with scarce event data and imbalances in the size of comparison groups. DATA SYNTHESIS: Thirty-seven studies (1991 patients were included. We found no randomised trial. The primary analysis revealed a large treatment effect in favour of antiplatelets for preventing the primary composite outcome of ischaemic stroke, intracranial haemorrhage or death within the first 3 months after treatment initiation (relative risk 0.32, 95% credibility interval 0.12 to 0.63, while the degree of between-study heterogeneity was moderate (τ(2 = 0.18. In an analysis restricted to studies of higher methodological quality, the possible advantage of antiplatelets over anticoagulants was less obvious than in the main analysis (relative risk 0.73, 95% credibility interval 0.17 to 2.30. CONCLUSION: In view of these results and the safety advantages, easier usage and lower cost of antiplatelets, we conclude that antiplatelets should be given precedence over anticoagulants as a first line treatment in patients with cervical artery dissection unless results of an adequately powered randomised trial suggest the opposite.

    Full Text Available Aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. This fatal disorder is hard to diagnose, especially in young patients. We present the case of aortic dissection in a 15-year-old boy referred to the Emergency Department of Yazd University of Medical Sciences in November 2015. The patient presented to our department with sudden acute chest pain. Emergent computed tomography (CT scanning of the brain, chest, and abdomen reflected bilateral pleural effusion, biluminal aorta, arterial flap in the upper part of the abdominal aorta, and dilated small bowl loop. The patient did not have any aortic dissection risk factors such as history of connective tissue disease, congenital heart disease, coarctation of the aorta, and hypertension. The only noticeable point in the patient’s history was swimming two hours before the onset of the chest pain. Aortic dissection is a rare differential diagnosis in children with acute sudden chest pain.

    Compartment syndrome is a clinical condition associated with decreased blood circulation that can lead to swelling of tissue in limited space. Several factors including lithotomy position, prolonged surgery, intermittent pneumatic compressor, and reperfusion after treatment of arterial thrombosis may contribute to compartment syndrome. However, compartment syndrome rarely occurs after gynecologic surgery. In this case, the patient was diagnosed as compartment syndrome due to reperfusion injury after treatment of arterial thrombosis, which occurred after laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer. Despite its rarity, prevention and identifying the risk factors of complication should be performed perioperatively; furthermore, gynecologist should be aware of the possibility of complications.

    Titanium plates used for the internal fixation of long bone fractures cause significant artefact on CT scans but have not been reported to affect digital subtraction CT angiography. We present a patient with clinical suspicion of popliteal artery injury following a high tibial osteotomy. The osteotomy was stabilised with a titanium locking plate. During the digital subtraction process used to produce reconstruction CT angiography, removal of artefact caused by the titanium plate produced CT images mimicking the appearance of a popliteal artery dissection. The imaging inaccuracy was realised prior to the patient undergoing further intervention. We highlight the potential error caused by titanium plates on digital subtraction CT angiography and recommend careful analysis of such images prior to further treatment.

    Full Text Available ABSTRACT: Vascular variations are usually the result of deve lopmental anomaly during the formation of blood vessels in any respective part of the body. In this case a rare unilateral variation was found on the left upper limb during rou tine dissection in the Department of Anatomy. Brachial artery divided into radial artery and a common trunk. The common trunk in turn divided into ulnar, median and common inteross eous artery. The median artery was palmar type, had two proper palmar digital branches in t he palm. The radial artery had normal course in the forearm till the junction between upper two third and lower one third where it turned dorsally and reached the anatomical snuff bo x and ran superficial to the abductor pollicis longus, extensor carpi radialis brevis and extensor carpi radialis longus along the cephalic vein medially and superficial branch of radial nerve late rally. The median artery, arose from the common trunk, had pierced the median nerve about 4cm from its origin then ran along the median nerve in the forearm thereby reached the palm where it gave off two common palmar digital branches but did not anastomose with the ul nar artery hence formed incomplete superficial palmar arch. But on the right side no suc h variations found. These vascular variations have been studied in detail and their cl inical implications and embryological significance are emphasized.

    Full Text Available The retreatment of recurrent intracranial vertebral artery dissecting aneurysms (VADAs after stent assisted coiling (SAC has not yet been studied. The purpose of this study was to evaluate the strategies and outcomes for retreatment of recurrent VADAs after SAC.Between September 2009 and November 2013, six consecutive patients presenting with recurrent intracranial VADAs after SAC were enrolled in this study. They were all male with age ranging from 29 to 54 years (mean age, 46.2 years. The procedures of treatments and angiographic and clinical follow-up were reviewed retrospectively. Retreatment modalities were selected individually according to the characteristics of recurrence. The outcomes of retreatment were evaluated by angiographic and clinical follow-up.Six patients with recurrent intracranial VADAs after SAC were retreated, with second SAC in three patients, coil embolization, double overlapping stents placement and endovascular occlusion with aneurysm trapping in one patient, respectively. Immediate angiographic outcomes of retreatment were: complete occlusion in three patients, nearly complete occlusion in two patients, and contrast medium retention in dissecting aneurysm in one patient. All cases were technically successful. No complications related to endovascular procedures occurred. Angiographic follow-up was available in all five patients treated with second SAC or double overlapping stents, which was complete occlusion in four patients, obliteration of parent artery in one patient, showing no recurrence at 4-11 months (mean: 8.6 months. Clinical follow-up was performed in all six patients at 11-51 months after initial endovascular treatment and at 9-43 months after retreatment. The mRS of last clinical follow-up was excellent in five patients and mild disability in only one patient.Endovascular retreatment is feasible and effective for recurrent intracranial VADAs after SAC. Individualized strategies of retreatment should be

    We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left, passing the anterior to the pulmonary artery, and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm, so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.

    Use of the Pipeline embolization device (PED) has increased based on studies about its safety and effectiveness, and new reports that describe peri- or postprocedural complications are now emerging. We report a rare periprocedural device-related complication that occurred during endovascular treatment with the pipeline embolization device for a dissecting aneurysm on the vertebral artery. A 55-year old woman was admitted due to left medullary infarction, and angiography showed a fusiform dilatation in the left vertebral artery that was suspicious for dissecting aneurysm. Endovascular treatment with PED was planned. Under general anesthesia, the procedure was performed without significant problems and a PED was deployed in an appropriate position. However, in the final step of the procedure, the distal tip of the PED delivery wire became engaged within a small branch of the posterior cerebral artery and fractured. Fortunately, imaging studies after the procedure revealed neither hemorrhagic nor ischemic stroke, and the patient recovered without neurological morbidities except initial symptoms.

    A rare case of aortic arch aneurysm combined with chronic aortic dissection is reported. Because the visceral arteries originated from different, equivalently perfused lumens and the descending aorta was circumferentially calcified (porcelain aorta) limiting the possibilities of anastomosing, careful planning of the surgical strategy was of utmost importance. The complex surgery consisted of ascending and total arch replacement using the 'frozen elephant trunk' technique with Thoraflex™ Hybrid Prosthesis (Vascutek, Terumo, Inchinnan, Scotland); however, before insertion of the stent graft, an angioscopic resection of the dissection membrane in the proximal part of the descending aorta was carried out to ensure a complete expansion of the distal edge of the stent within the entire common lumen of the aorta and unimpaired distal flow in both lumens below the stent graft. The surgery and the postoperative course were uneventful.

    Full Text Available Introduction. Reconstruction of chronic type B dissection and thoracoabdominal aortic aneurysm (TAAA remaining after the emergency reconstruction of the ascending thoracic aorta and aortic arch for acute type A dissection represents one of the major surgical challenges. Complications of chronic type B dissection are aneurysmal formation and rupture of an aortic aneurysm with a high mortality rate. We presented a case of visceral hybrid reconstruction of TAAA secondary to chronic dissection type B after the Bentall procedure with the elephant trunk technique due to acute type A aortic dissection in a high-risk patient. Case report. A 62 year-old woman was admitted to our institution for reconstruction of Crawford type I TAAA secondary to chronic dissection. The patient had had an acute type A aortic dissection 3 years before and undergone reconstruction by the Bentall procedure with the elephant trunk technique with valve replacement. On admission the patient had coronary artery disease (myocardial infarction, two times in the past 3 years, congestive heart disease with ejection fraction of 25% and chronic obstructive pulmonary disease. On computed tomography (CT of the aorta TAAA was revealed with a maximum diameter of 93 mm in the descending thoracic aorta secondary to chronic dissection. All the visceral arteries originated from the true lumen with exception of the celiac artery (CA, and the end of chronic dissection was below the origin of the superior mesenteric artery (SMA. The patient was operated on using surgical visceral reconstruction of the SMA, CA and the right renal artery (RRA as the first procedure. Postoperative course was without complications. Endovascular TAAA reconstruction was performed as the second procedure one month later, when the elephant trunk was used as the proximal landing zone for the endograft, and distal landing zone was the level of origin of the RRA. Postoperatively, the patient had no neurological deficit and

    Full Text Available Abstract Introduction Due to recent advances in imaging diagnostic techniques, there are an increasing number of case reports of segmental arterial mediolysis. However, there are only a limited number of reports on segmental arterial mediolysis-related abnormalities of abdominal organs other than the intestine. This report describes a case of segmental arterial mediolysis accompanied by abnormalities of abdominal organs without clinical symptoms. Case presentation A 52-year-old Japanese man with hematuria and no prior medical history was referred to a urologist and was diagnosed as having urinary bladder cancer. He underwent trans-urethral resection of the bladder tumor and intra-vesical instillation therapy, which was followed by observation. During follow-up, although no abdominal symptoms were observed, an abdominal computed tomography scan revealed a dissection of the superior mesenteric artery. A false lumen partially occluded by a thrombus was located distal to this occlusion. The lumen was irregularly shaped with narrow and wide sections. Similar irregularities were also observed in the wall of the inferior mesenteric artery. Arterial dissection with thromboembolism in the left renal artery and renal infarction was also observed. Follow-up computed tomography after two months revealed an enlargement of the pancreatic tail adjacent to the splenic artery. Follow-up three-dimensional computed tomography showed gradual re-expansion of the true lumen of the superior mesenteric artery, improvement in arterial wall irregularities, and a reduction in the pancreas enlargement and renal infarction. Over the following 15 months, these changes gradually normalized. On the basis of the vascular changes in multiple arterial systems that resolved spontaneously, we considered that the lesions were associated with segmental arterial mediolysis. Conclusions We present a rare case of segmental arterial mediolysis accompanied by abnormalities of abdominal

    Full Text Available A 30-year-old previously healthy female, who was six-week postpartum, experienced sudden collapse and tonic-clonic seizure. Emergency medicine services arrived at the scene and the patient was found to be in ventricular fibrillation. Advanced cardiovascular life support (ACLS was initiated with return of spontaneous circulation. Afterwards, her initial EKG showed atrial fibrillation with rapid ventricular rate, ST elevation in leads II, III, and aVF, and ST depression in V2–V4. She was transferred to a tertiary care hospital where emergent angiogram was performed revealing obstruction of blood flow in the proximal and mid right coronary artery (RCA. A hazy and irregularly contoured appearance of the RCA was consistent with diagnosis of fibromuscular dysplasia. Subsequently, intravascular ultrasonogram (IVUS was performed which confirmed the diagnosis of RCA dissection. Successful revascularization of the RCA was performed using two bare mental stents. After a complicated course in hospital, she was discharged in stable condition and did very well overall.

    Spontaneous cervical artery dissection (sCAD) is a common cause of stroke in patients below 55 years of age. Hereditary connective tissue disorders, including Ehlers-Danlos syndrome type IV, have been associated with sCAD and suprastructural abnormalities of both collagen fibrils and elastic fibers have been found by transmission electron microscopy in the dermis of about 50% of sCAD patients. Here, we investigated dermal connective tissue abnormalities using a novel method. Transmission and immunogold electron microscopy were used to study mechanically generated fragments of dermal matrix suprastructures, in particular collagen fibrils. Analysis of dermal tissue of sCAD patients revealed structurally abnormal collagen fibrils with irregularly contoured surfaces and increased diameters, often associated with a faint or absent banding pattern. Interestingly, only a small number of fibrils displayed short abnormal sections along the length of the fibril. Collagens I and III were present in normal as well as abnormal sections of the fibrils.However, immunogold labeling for the two proteins was strongly increased in abnormal sections.A systematic blinded investigation of skin biopsies of 31 sCAD patients and 17 controls revealed abnormal collagen fibrils in 7 sCAD patients but none of the controls. We conclude that approximately 20% of sCAD patients show collagen fibril alterations, establishing a promising basis for further investigation of connective tissue aberrations in skin biopsies of sCAD patients.

    This study describes the technical handling and the diagnostic evaluation of skin biopsies in order to standardize the assessment of the delicate morphologic abnormalities that are found in patients with spontaneous cervical artery dissections (sCAD). Skin biopsies from 126 patients with sCAD and from 29 healthy relatives were analyzed. The morphology of the connective tissue was normal in 54 patients with sCAD (43%) and aberrant in 72 patients with sCAD (57%). These latter patients were classified into three groups: in 43 patients, we repeatedly observed composite collagen fibrils and elastic fibers with fragmentation and minicalcifications. In 13 further patients, the dermis was significantly thinner than in healthy subjects. The collagen fibers contained fibrils with highly variable diameters. In a third group of 16 sCAD patients, the abnormalities were restricted to the elastic fibers (with fragmentation and minicalcifications) without significant alterations in the morphology of the collagen fibrils. The finding of different morphologic classes of aberrations among patients suggests that the connective tissue defects are genetically heterogeneous. The segregation of the connective tissue phenotype in three families suggested an autosomal dominant pattern of inheritance.

    2016-04-01

    Full Text Available Pulmonary artery intimal sarcomas are rare and lethal malignant tumors that typically affect larger vessels: the aorta, inferior vena cava, and pulmonary arteries. Since symptoms and imaging of pulmonary arterial intimal sarcomas mimic pulmonary thromboembolism, the differential diagnosis of a patient presenting with chest pain, dyspnea, and filling defect within the pulmonary arteries should include intimal sarcoma. Often right ventricular failure is observed due to pulmonary hypertension caused by the obstructive effect of the tumor and concomitant chronic thromboembolism. We report the case of a 72-year-old African-American male with arterial intimal sarcoma of the left and right pulmonary artery with extension through the right artery into the bronchus and right lung.

    Fifteen patients with suspected or known aortic dissection were imaged with magnetic resonance (MR). Thirteen of these patients were eventually shown to have dissection. In most instances the diagnosis was established by aortography and/or computed tomography (CT) prior to the MR study. Surgical proof (6/13) and/or aortographic proof (10/13) were available in 11/13 patients with aortic dissection. MR demonstrated the intimal flap and determined whether the dissection was type A or type B. In addition, MR: differentiated between the true and false lumens; determined the origins of the celiac, superior mesenteric, and renal arteries from the true or false lumen in the cases where the dissection extended into the abdominal aorta (8/12); allowed post-surgical surveillance of the dissection; and identified aortoannular ectasia in the three patients who had Marfan syndrome. In addition to the 13 cases with dissection, there were two cases in whom the diagnosis of dissection was excluded by MR. Our early experience suggests that MR can serve as the initial imaging test in clinically suspected cases of aortic dissection and that the information provided by MR is sufficient to manage many cases. Additionally, MR obviates the use of iodinated contrast media.

    Full Text Available Pulmonary artery agenesis is a rare congenital abnormality in which atresia was encountered in the short segment of the right or left pulmonary arteries. It can be isolated or associated with cardiac abnormalities such as tetralogy of Fallot, septal defects or pulmonary stenosis.The majority of cases are diagnosed in childhood whereas some cases yield no symptoms until adulthood. We evaluated retrospectively 5 pulmonary artery agenesis cases diagnosed in our clinics between 1998-2010 with respect to the literature.

    Full Text Available Background/Aim. Hypertension is a known predictor of proximal aortic dissection, but it is not commonly present in these patients on presentation. The associations between ascending aorta with left ventricular hypertrophy, cardiovascular risk factors and coronary atherosclerosis, and outcome of these patients are not fully elucidated. Methods. This retrospective study included 55 consecutive patients with acute type A aortic dissection treated surgically in our institution during the last 2 years. The diagnosis was based on imaging studies. Diameter of ascending aorta was measured with echocardiography. Results. The mean age of the patients was 55.4 ± 12.19 years, and 72.7% were men. A history of arterial hypertension was present in 76.4% of the patients. Maximal ascending aorta diameter was 4.09 ± 0.59 cm, while patients with frank aneurysm accounted for 5.5%. Systolic blood pressure on admission was < 150 mmHg in 58.2% of the patients. Diastolic blood pressure on admission was < 90 mmHg in 54.5% of the patients. Mean arterial pressure on admission was 104.9 ± 24.6 mmHg. No correlations were demonstrated between maximal ascending aorta diameter and diameter of the left ventricular wall, any obtained risk factor and with coronary artery atherosclerosis (p > 0.05. After six months 11 (20% patients died, while intrahospital mortality was 72%. According to logistic regression analysis which included traditional risk factors, echo parameters, coronary artery disease and logistic euro scor, mean arterial blood pressure was the independent predictor of a six-month mortality [RR 0.956; CI (0.918-0.994 ; p = 0.024]. Conclusion. In our population the acute type A aortic dissection occurred rarely in the setting of frank ascending aortic aneurysms > 5.0 cm. The majority of patients had a history of arterial hypertension. A history of arterial hypertension was not associated with maximal ascending aorta diameter. Mean arterial blood pressure was the

    The purpose of this study was to assess the incidence of spontaneous renal artery dissection (SRAD) as a cause of acute renal infarction, and to evaluate the clinical and multidetector computed tomography (MDCT) findings of SRAD. From November 2011 to January 2014, 35 patients who were diagnosed with acute renal infarction by MDCT were included. We analyzed the 35 MDCT data sets and medical records retrospectively, and compared clinical and imaging features of SRAD with an embolism, using Fisher's exact test and the Mann-Whitney test. The most common cause of acute renal infarction was an embolism, and SRAD was the second most common cause. SRAD patients had new-onset hypertension more frequently than embolic patients. Embolic patients were found to have increased C-reactive protein (CRP) more often than SRAD patients. Laboratory results, including tests for lactate dehydrogenase (LDH) and blood urea nitrogen (BUN), and the BUN/creatinine ratio (BCR) were significantly higher in embolic patients than SRAD patients. Bilateral renal involvement was detected in embolic patients more often than in SRAD patients. MDCT images of SRAD patients showed the stenosis of the true lumen, due to compression by a thrombosed false lumen. None of SRAD patients progressed to an estimated glomerular filtration rate renal disease during the follow-up period. SRAD is not a rare cause of acute renal infarction, and it has a benign clinical course. It should be considered in a differential diagnosis of acute renal infarction, particularly in patients with new-onset hypertension, unilateral renal involvement, and normal ranges of CRP, LDH, BUN, and BCR.

    Mélodie Aubart

    Full Text Available BACKGROUND: Severe osteoarthritis and thoracic aortic aneurysms have recently been associated with mutations in the SMAD3 gene, but the full clinical spectrum is incompletely defined. METHODS: All SMAD3 gene mutation carriers coming to our centre and their families were investigated prospectively with a structured panel including standardized clinical workup, blood tests, total body computed tomography, joint X-rays. Electroneuromyography was performed in selected cases. RESULTS: Thirty-four SMAD3 gene mutation carriers coming to our centre were identified and 16 relatives were considered affected because of aortic surgery or sudden death (total 50 subjects. Aortic disease was present in 72%, complicated with aortic dissection, surgery or sudden death in 56% at a mean age of 45 years. Aneurysm or tortuosity of the neck arteries was present in 78%, other arteries were affected in 44%, including dissection of coronary artery. Overall, 95% of mutation carriers displayed either aortic or extra-aortic arterial disease. Acrocyanosis was also present in the majority of patients. Osteoarticular manifestations were recorded in all patients. Joint involvement could be severe requiring surgery in young patients, of unusual localization such as tarsus or shoulder, or mimicking crystalline arthropathy with fibrocartilage calcifications. Sixty eight percent of patients displayed neurological symptoms, and 9 suffered peripheral neuropathy. Electroneuromyography revealed an axonal motor and sensory neuropathy in 3 different families, very evocative of type II Charcot-Marie-Tooth (CMT2 disease, although none had mutations in the known CMT2 genes. Autoimmune features including Sjogren's disease, rheumatoid arthritis, Hashimoto's disease, or isolated autoantibodies- were found in 36% of patients. INTERPRETATION: SMAD3 gene mutations are associated with aortic dilatation and osteoarthritis, but also autoimmunity and peripheral neuropathy which mimics type II

    Full Text Available Spontaneous coronary artery dissection (SCAD is a very rare disease, associated with high mortality rate, whose etiology and pathogenesis are poorly understood. Its sporadic nature and the varied angiographic extent make firm recommendations regarding revascularization impossible. The case described is that of a young, otherwise healthy woman, without a known underlying condition which may lead to SCAD, but with a history of intense psychological stress. We managed the patient with a conservative approach based on watchful waiting, medical therapy, and plain old balloon angioplasty (POBA with low inflation atmospheres.

    We report a case in which a stent graft and an Amplatzer(®) vascular plug (AVP) were effective for the treatment of chronic aneurysmal aortic dissection. The patient was a 52-year-old man. At 45 years of age, he developed acute aortic dissection, for which he underwent surgery 4 times with prosthetic graft replacement in the abdominal aorta, descending thoracic, ascending aorta (without neck branch reconstruction), and thoracoabdominal aorta with the reconstruction of the celiac, superior mesenteric, and bilateral renal arteries. At the time of thoracoabdominal aortic surgery, strong adhesion was evident, particularly in the thoracoabdominal area. The adhesion was dissected in a part of the chest, and prosthetic graft replacement was performed the following day. Subsequently, the dissection of the residual distal aortic arch enlarged, and the patient was examined at our hospital. Computed tomography (CT) revealed a small intimal tear at the site of anastomosis distal to the graft in the ascending aorta and a large intimal tear in the descending thoracic aorta with a maximum diameter of 67 mm. Furthermore, open repair by prosthetic graft replacement seemed difficult; therefore, treatment with stent grafting was considered. Because the prosthetic graft in the abdomen was extremely tortuous, stent-graft insertion via the femoral artery seemed to be impossible. The planned treatment involved the placement of a thoracic stent graft using the chimney technique which included reconstruction of the brachiocephalic artery and left common carotid arteries using chimney stent graft and coverage of the left subclavian artery. The thoracic stent graft was planned to be inserted via the abdominal prosthetic graft site because the abdominal prosthetic graft was crooked and was located close to the body surface. However, a small intimal tear distal to the graft in the ascending aorta which had not been revealed by intraoperative aortography was detected by the selective

    A 44-year-old man presented with very severe right upper quadrant pain of sudden onset. This was exacerbated by movement but unaffected by food or defaecation. It was continuous-day and night -but resolved over a 1-week period. The physical examination was normal at presentation, by which time the pain had resolved. His white cell count, alanine transaminase and C reactive protein were elevated but normalised after 10 days. An abdominal CT showed low density lesions in the right kidney consistent with segmental infarcts. CT angiogram showed a dissection of the right renal artery. The patient remained asymptomatic and normotensive when reviewed 1 month later.

    Ischemic stroke secondary to aortic dissection is not uncommon. We present a patient with left hemiplegia secondary to Stanford type A aortic dissection extending to the supra-aortic vessels, which was precipitated by rifle butt recoil chest injury. The diagnosis of aortic dissection was delayed due to various factors. Finally, the patient underwent successful Bentall procedure with complete resolution of symptoms. This case emphasizes the need for caution in the use of firearms for recreation and to take precautions in preventing such incidents. In addition, this case illustrates the need for prompt cardiovascular physical examination in patients presenting with stroke.

    Pseudoaneurysms of the superficial temporal artery are an uncommon vascular lesion of the external carotid system and most often the result of blunt head trauma. The frequency of pseudoaneurysms of the superficial temporal artery developing after craniotomy is exceedingly low and only a few cases have been reported. We present a case of pseudoaneurysm of this type in a 45-year-old male who underwent craniotomy for excision of meningioma. One month postoperatively, the craniotomy flap exhibited an enormous diffuse pulsate swelling. The suspected diagnosis of pseudoaneurysm arising from superficial temporal artery was confirmed on angiography. Surgical excision was done and no recurrences of the tumor or aneurysm were noted on subsequent follow up. PMID:26501064

    The authors reported a subclavian artery stenting (SAS) using gadolinium contrast medium. The patient was a 65-year-old female who presented dizziness and right upper extremity pain with movement. Digital subtraction angiography revealed right subclavian artery occlusion with subclavian steal phenomenon. We tried to treat this lesion using SAS. However, iodinated contrast medium caused the allergy in this patient and the treatment was discontinued. Therefore, SAS was performed with gadolinium contrast medium. Using gadolinium contrast medium, it is possible to confirm large arteries like innominate artery and subclavian artery. The stenting procedure was performed without complication. The usage of gadolinium contrast medium has the limit and some strategies are important to reduce the usage of gadolinium contrast medium in SAS. First, PercuSurge GuardWire® was placed in the right internal carotid artery to confirm the anatomy, to decide working angle, and to treat the common carotid artery in case of dissection. Second, a "U" shaped guide wire was placed in the distal end from the brachial artery. Guide wire from femoral side was able to pass the lesion at midpoint of the "U" shaped one. SAS using gadolinium contrast medium may be an alternative treatment if a patient with subclavian artery stenosis or occlusion is allergic to iodinated contrast medium.

    Acute intramural hematoma resulting from cerebral artery dissection is usually visualized as a region of intermediate signal intensity on T1-weighted images (WI). This often causes problems with distinguishing acute atheromatous lesions from surrounding parenchyma and dissection. The present study aimed to determine whether or not R2* maps generated by the iterative decomposition of water and fat with echo asymmetry and least-squares estimation quantitation sequence (IDEAL IQ) can distinguish cerebral artery dissection more effectively than three-dimensional variable refocusing flip angle TSE T1WI (T1-CUBE) and T2*WI. We reviewed data from nine patients with arterial dissection who were assessed by MR images including R2* maps, T2*WI, T1-CUBE, and 3D time-of-flight (TOF)-MRA. We visually assessed intramural hematomas in each patient as positive (clearly visible susceptibility effect reflecting intramural hematoma as hyperintensity on R2* map and hypointensity on T2*WI), negative (absent intramural hematoma), equivocal (difficult to distinguish between intramural hematoma and other paramagnetic substances such as veins, vessel wall calcification, or hemorrhage) and not evaluable (difficult to determine intramural hematoma due to susceptibility artifacts arising from skull base). Eight of nine patients were assessed during the acute phase. Lesions in all eight patients were positive for intramural hematoma corresponding to dissection sites on R2* maps, while two lesions were positive on T2*WI and three lesions showed high-intensity on T1-CUBE reflected intramural hematoma during the acute phase. R2* maps generated using IDEAL IQ can detect acute intramural hematoma associated with cerebral artery dissection more effectively than T2*WI and earlier than T1-CUBE. (orig.)

    Full Text Available Abstract Introduction The variations in the morphological characteristics of the extra-hepatic biliary system are interesting. Case presentation During the dissection of cadavers to study the morphological characteristics of the extra-hepatic biliary system, a 46-year-old male cadaver was found to have drainage of the common hepatic duct drains directly into the gall bladder neck. The right and left hepatic ducts were not seen extra-hepatically. Further drainage of the bile away from the gallbladder and into the duodenum was provided by the cystic duct. Formation of the common bile duct by the union of the common hepatic duct and cystic duct was absent. Further more the right hepatic artery was found to be communicating with the left hepatic artery by a "bridging artery" after giving rise to the cystic artery. An accessory hepatic artery originated from the "bridging artery" forming a "cruciate" hepatic arterial anastomosis. Conclusion Combination of a Hepaticocystic duct and an aberrant variation in the extra-hepatic arterial system is extremely rare.

    Unilateral absence of a pulmonary artery is an uncommon anomaly, which presents as an isolated lesion or in combination with other congenital heart disease such as TOF or PDA. We encountered three cases of isolated unilateral absence of a pulmonary artery; one was left pulmonary artery agenesis with right sided aortic arch and the others were right pulmonary artery agenesis with left sided aortic arch. Plain chest radiograph showed considerable loss of unilateral lung volume and lack of ipsilateral hilar shadow. Pulmonary angiogram which was done in two cases, revealed proximal interruption of a pulmonary artery. Chest CT was done in only one case, on which right pulmonary artery was absent and was replaced by adipose tissue. CT with its clean demonstration pulmonary artery without any evidence of acquired obstruction of a pulmonary artery by pulmonary embolism or tumor invasion, maybe a valuable method for evaluation of the unilateral absence of a pulmonary artery.

    2014-07-01

    Full Text Available Background: Acute aortic dissection can occur at the time of intense physical exertion in strength-trained athletes like weight lifters, bodybuilders, throwers, and wrestlers. Rapid rise in blood pressure and history of hypertension are the most common causes of aortic dissection in athletes. It is a very tragic event because of its high mortality rate of about 32% in young patients. We report a case of aortic dissection in a young weightlifter with a history of anabolic steroid usage with an extensive intimal tear of the aorta at Sino tubular junction and arch. All athletes must be assessed for predisposing factors for aortic dissection, and all patients should be encouraged to undergo appropriate diagnostic studies, like echocardiography and blood pressure monitoring while weightlifting to recognize possible predisposing factors for aortic dissection. Athletes who do have a problem should be encouraged to avoid or limit their exercise or activity by their cardiologist. It is vital that this disastrous event be prevented in young people. In conclusion, although a rare occurrence, AD should be considered in symptomatic patients with any family history of early cardiac deaths, a history suggestive of a connective tissue disorder (that is, multiple joint surgeries or who practice weightlifting.

    Literatures on vasculature of upper limbs are crammed with reports of distinctly deviant version of normally prevalent vessels having modified origins, altered branching and odd courses. A unique anatomical variation in vascular pattern was observed during routine dissection of right upper limb in gross anatomy laboratory, AIIMS, New Delhi, India. The brachial artery was placed superficial to median nerve in the arm and therefore it was called superficial brachial artery. In the cubital fossa, 2.8 cm distal to intercondylar line of elbow joint, this superficial brachial artery terminated by trifurcation into radial, common interosseous and ulnar branches. Strikingly the ulnar branch, after its origin ran superficially over the median nerve and epitrochlear superficial flexor group of muscles of forearm in succession for the initial third of its course in the forearm, consequently it was addressed as superficial ulnar artery. The existence of superficial brachial artery in place of normal brachial artery, its termination by trifurcation into radial, common interosseous and superficial ulnar arteries with remarkably different courses, leads to confusing disposition of structures in the arm, cubital fossa and in the forearm and collectively makes this myriad of anatomical variations even rarer. The clinico-embryological revelations for combination of these unconventional observations, apprises and guides the specialized medical personnel attempting blind and invasive procedures in brachium and ante-brachium. This case report depicts the anatomical perspective and clinical implications on confronting a rare variant vasculature architecture pattern of upper limb.

    Aortic dissection is often misdiagnosed, especially among young patients, and it is associated with a high mortality rate. We present here a case of fatal acute aortic dissection in a young man who was misdiagnosed with pericarditis. We reviewed the literature of acute aortic dissection in young people and we focused particularly on clinical presentations, outcomes and investigations of aortic dissection. We report a case of a 33-year-old man with a history of uncontrolled hypertension with acute pleuretic chest pain who was transferred to our hospital for suspected pulmonary embolism and died of acute hemorragic pericardial effusion from an ascendant aortic dissection. We should never rule out aortic dissection off our differential diagnosis on the sole basis of a patient's young age.

    Woven coronary artery is an extremely rare and clearly undefined coronary malformation. Up to now, very few cases have been reported. In this anomaly, epicardial coronary artery are branched into thin channels at any segment of the coronary artery and then these longitudinal twisted thin channels merge again as the main coronary lumen. This anomaly is regarded as a benign condition since there is completely normal blood flow after the distal segment of the abnormal coronary artery. In this case report, we present a 48-year-old male patient with a woven coronary artery anomaly in the circumflex artery and who had been followed up for 5 years.

Herein, we report the case of a 51-year-old man who presented with sudden-onset paraplegia and ischemia of the legs, with no chest or back pain. His medical history included coronary artery bypass grafting. Physical examination revealed pulseless lower extremities, and computed tomography showed aortic dissection from the ascending aorta to the common iliac arteries bilaterally. A lumbar catheter was inserted for cerebrospinal fluid drainage, and axillary arterial cannulation was established. With the use of cardiopulmonary bypass, the aortic dissection was corrected, and the previous coronary artery grafts were reattached. The surgery restored spinal and lower-extremity perfusion, and the patient walked unaided from the hospital upon his discharge 5 days later. Although acute aortic dissection presenting as paraplegia is rare, it should be considered in patients who have pulseless femoral arteries bilaterally and sudden-onset paraplegia, despite no pain in the chest or back. Prompt diagnosis and intervention can prevent morbidity and death.

    Full Text Available Context Segmental arterial mediolysis is an uncommon, non-atherosclerotic, non-inflammatory arteriopathy that involvesareas of dissecting aneurysms and strictures that are caused by outer media lysis of the arterial wall from areas of medialnecrosis of uncertain pathogenesis. It has a predilection for splanchnic arteries and often presents as abdominal pain orhemorrhage in late middle-aged and elderly patients. Diagnosis can be established by computed tomography angiography,magnetic resonance angiography, or angiogram by visualizing typical abnormalities, in addition to excluding othervasculitides. Histological confirmation is the gold standard but is not easily accessible and, as such, is not frequentlyperformed. Case report Here we present an updated review of the literature and a case of segmental arterial mediolysis thatpresented with spontaneous intra-abdominal bleeding near the pancreas that was originally misdiagnosed as hemorrhagicpancreatitis. Conclusion Diagnosis is important because immunosuppressants for vasculitis can worsen the arteriopathy.Segmental arterial mediolysis can be self-limiting without treatment or may require urgent surgical or endovascular therapyfor bleeding and carries a 50% mortality rate. Therefore, it should be included in the differential of causes of abdominal painas well as in cases of unexplained abdominal hemorrhage.

    Here, we report a case of a 30-year-old woman who presented with primary postpartum hemorrhage due to uterine atony. She received uterine artery embolization (UAE). During left internal iliac arteriography, an aberrant left ovarian artery originating from the left iliolumbar artery was visualized. The aberrant left ovarian artery was connected to the left uterine artery via prominent collateral vessels. It supplied a significant amount of blood to the fundus of the uterus. Bilateral hypertrophied uterine arteries were embolized very carefully so that the embolic material did not reflux into the aberrant left ovarian artery. After the procedure, her vaginal bleeding was successfully controlled. Accurate understanding of anatomical variations of the ovarian artery is essential to avoid failure in controlling postpartum hemorrhage with UAE.

    A case of a 12 cm giant renal artery aneurysm (RAA) in an 59-year-old woman is reported. The patient was referred to our hospital for flank pain and spot hematuria. Ultrasonography (US) revealed some wide lacunar areas in her right kidney and a thin cortex. Three-dimensional computed tomography (3D-CT) revealed a giant right renal arteriovenous malformation (AVM). AngioCT scan showed a pervious right renal artery. The cavities of the right kidney were dilated and the parenchyma was markedly reduced. Two months later the patient underwent an open resection of the aneurysm and a right nephrectomy. She had an uneventful recovery and a healthy status (last follow-up: 9 month). In this particular case, a safe approach is the transabdominal approach since the aneurysm was very large, friable, and located on the right side. This report confirms the opportunity of a planned nephrectomy once there is adequate renal reserve in the opposite kidney using a midline approach.

    Full Text Available Abstract Background Variations in the major arteries of the upper limb are estimated to be present in up to one fifth of people, and may have significant clinical implications. Case presentation During routine cadaveric dissection of a 69-year-old fresh female cadaver, a superficial brachioulnar artery with an aberrant path was found bilaterally. The superficial brachioulnar artery originated at midarm level from the brachial artery, pierced the brachial fascia immediately proximal to the elbow, crossed superficial to the muscles that originated from the medial epicondyle, and ran over the pronator teres muscle in a doubling of the antebrachial fascia. It then dipped into the forearm fascia, in the gap between the flexor carpi radialis and the palmaris longus. Subsequently, it ran deep to the palmaris longus muscle belly, and superficially to the flexor digitorum superficialis muscle, reaching the gap between the latter and the flexor carpi ulnaris muscle, where it assumed is usual position lateral to the ulnar nerve. Conclusion As far as the authors could determine, this variant of the superficial brachioulnar artery has only been described twice before in the literature. The existence of such a variant is of particular clinical significance, as these arteries are more susceptible to trauma, and can be easily confused with superficial veins during medical and surgical procedures, potentially leading to iatrogenic distal limb ischemia.

    Massive hemoptysis caused by pulmonary artery pseudoaneurysms is uncommon, and endovascular treatment such as coil embolization is the first choice for treating pulmonary artery pseudoaneurysms. Various embolic agents could be used according to the angiographic findings, yet embolization with thrombin injection is very rare. Herein, we describe a case of a pulmonary artery pseudoaneurysm that was successfully treated by endovascular thrombin injection using a microcatheter because of the difficulty in performing a coil embolization due to a short feeding artery.

    Large cerebral aneurysms of the basilar apex are difficult to treat. Recently, endovascular treatment has mitigated much of the morbidity associated with treating these lesions. However, the morphology of aneurysms of the vertebrobasilar system can preclude endovascular treatment. Rapid ventricular pacing (RVP) facilitates open surgical treatment of cerebral aneurysms. It can assist in reducing the pressure of the neck of the aneurysm, allowing safe application of a clip. The authors present a case of a pediatric patient who developed a basilar artery pseudoaneurysm that required surgery. Given the large size of the aneurysm, RVP was performed, allowing the surgeons to dissect the dome of the aneurysm from the surrounding tissue and pontine perforating branches away from the lesion to safely clip the lesion. The patient had an uneventful recovery. To the authors' knowledge, this represents the first known case of RVP to aid in basilar artery clip occlusion in a pediatric patient.

    Full Text Available This report discusses the case of a chyle leak following a right axillary lymph node dissection for breast cancer. This presented as a sudden change in drainage character from a right axillary surgical drain from serous to milky white shortly after restarting a diet. The diagnosis of chyle leak was confirmed by laboratory testing of the fluid and managed with closed suction drainage. Chyle leak is a rare, but increasingly recognized complication following axillary clearance for breast cancer and melanoma.

    The most prevalent lesion of the vertebral artery is an atheromatous plaque located at its origin from the subclavian artery. A case of successful management of a symptomatic vertebral artery aneurysm due to Ehlers-Danlos syndrome is reported. The patient had asymptomatic posterior intracerebral artery dissection on the contralateral side. A common carotid artery to V-3 segment bypass using reversed saphenous vein graft was carried out. Avulsion of the V-2 segment occurred peroperatively and endovascular coil embolization of the vertebral artery aneurysm was performed. Endovascular equipment and training must be in the armamentarium of vascular surgeons as more complex cases are being treated, which demands new approaches for ultimate clinical success. This unique case outlines what might unexpectedly occur. Endovascular intervention as an adjuvant procedure provides a satisfactory outcome in what could have been a catastrophe.

    Background It is well known that conventional splenectomy,which requires careful handling and ligation of tissue of the splenic hilum,can easily cause complications such as splenic fever and pancreatic fistula.Here,we use the technique of dissection of the secondary branches of the splenic pedicle to handle the hilum in the portal hypertension patients who are subjected to splenectomy.Methods We retrospectively compared and analyzed the complications,postoperative hospital stay,operative time,and occurrence of hemorrhage in 121 patients with portal hypertension undergoing splenectomy and devascularization of the gastric cardia from January 1999 to December 2007.The selected cases consisted of 51 patients undergoing conventional splenectomy and 70 patients undergoing dissection of secondary branches of the splenic pedicle.In addition,we analyzed the relationship between size of the spleen and occurrence of complications.Results The incidence of pancreatic fistula and splenic fever (0/70 and 9/70) was lower in patients undergoing dissection of secondary branches of the splenic pedicle as compared with that of the conventional group (5/51 and 18/51 respectively).In addition,there was no significant difference in operative time and volume of blood loss between two groups.The spleen thickness of those patients who had pancreatic fistula and splenic fever was significantly greater than those without complications.Conclusions These results indicate that dissection of secondary branches of the splenic pedicle in portal hypertension patients undergoing splenectomy can decrease the incidence of splenic fever and pancreatic fistula,and shorten the postoperative hospital stay,especially in the patients with a large spleen.So dissection of secondary branches of the splenic pedicle is a valuable technique for splenectomy.

    Full Text Available Axillary artery and its branches are prone to have variations in their course. Knowledge about such variations are important for Radiologists in imaging techniques, Surgeons,Orthopedicians and Anesthetists in performing surgeries in the axilla and giving regional nerve blocks in the axilla.During dissection of a cadaver in the department of Anatomy, PSG IMS &R, Coimbatore, We observed a variation in the third part of right Axillary artery. From the common trunk, Subscapular artery, Anterior and Posterior circumflex humeral arteries and Profunda brachii artery arose. Third part of Axillary artery continued down as brachial artery. We are highlighting the variation in this study.

    Dissection of the ascending aorta (type A) following later after aortic valve replacement has been described with increasing frequency. This study analyzes the role of aortic valve replacement for the evolution of late dissection. In a series of 80 consecutive patients with type A dissection, a previous aortic valve replacement had been performed in 12 cases (15%). In addition to arterial hypertension (p syndrome (p factor for type A dissection. Dissection occurred 3 +/- 4 years after aortic valve replacement with a clinical and anatomical profile similar to classic dissection as proven by comparison to a group of 62 patients with classic dissection associated with arterial hypertension or Marfan syndrome. With 75% and 66%, respectively, 30 day and 1 year survival of patients with dissection following later after aortic valve replacement was similar to patients with classic type A dissection. Extensive thinning and/or fragility (p associated with a high risk for late dissection; this finding was substantiated by comparison to a control group of 10 consecutive patients with a similarly dilated aortic root but no dissection. Type and diameter of valve prostheses, cross-clamp time, NYHA functional class, and left ventricular ejection fraction were unrelated to late dissection. Previous aortic valve replacement is an independent predisposing factor for a dissection of the ascending aorta later. At the time of aortic valve replacement, prophylactic replacement or wrapping of the ascending aorta should be considered in patients with a thinned/fragile aortic wall even without a markedly dilated aortic root.

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior. Esse artigo relata o caso clínico de uma paciente portadora de adenocarcinoma de cólon sigmoide metastático irressecável, que evoluiu com vômitos incoercíveis. Realizou-se, então, trânsito intestinal que evidenciou dilatação gástrica importante, que se prolongava até a terceira porção duodenal, quadro radiológico compatível com pinçamento da artéria mesentérica superior.

    Full Text Available Spontaneous coronary artery dissection (SCAD is an uncommon entity, frequently presenting as ST-elevation myocardial infarction (MI or sudden cardiac death. It is usually reported in association with pregnancy and has a high mortality. We present here a case of asymptomatic dissection of the right coronary artery, incidentally detected, in a young normotensive male when coronary angiography was done following acute anterior wall MI. This patient had none of the risk factors to which SCAD is generally ascribed. While management of the infarct-related artery was clear-cut, whether or not to intervene for this nonocclusive dissection was a difficult decision. A conservative approach was finally adopted for the spontaneous dissection and the patient is faring well till date.

    Full Text Available Abstract Introduction Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system. Catheterization of a replaced left hepatic artery arising from a left gastric artery using a percutaneous catheter technique is sometimes difficult, despite the recent development of advanced interventional techniques. Case presentation We present a case of a 70-year-old Japanese man with multiple hepatocellular carcinomas in whom the replaced left hepatic artery arising from the left gastric artery needed to be embolized. After several failed procedures, the replaced left hepatic artery was successfully catheterized and embolized with a microcatheter and microcoils via the right gastric artery through the anastomosis. Conclusion A replaced left hepatic artery arising from a left gastric artery can be catheterized via a right gastric artery by using the appropriate microcatheter and microguidewires, and multiple hepatic arteries can be converted into a single supply.

    The dynamic, hemodynamic impact of a cervical dissection on an ipsilateral, intracranial saccular aneurysm has not been well illustrated. This 45-year-old female was found to have a small, supraclinoid aneurysm ipsilateral to a spontaneous cervical internal carotid artery dissection. With healing of the dissection, the aneurysm appeared to have significantly enlarged. Retrospective review of the magnetic resonance imaging (MRI) at the time of the initial dissection demonstrated thrombus, similar in overall morphology to the angiographic appearance of the "enlarged" aneurysm. As the dissection healed far proximal to the intradural portion of the internal carotid artery, this suggested that the aneurysm was likely a typical, saccular posterior communicating artery aneurysm that had thrombosed and then recanalized secondary to flow changes from the dissection. The aneurysm was coiled uneventfully, in distinction from more complex treatment approaches such as flow diversion or proximal occlusion to treat an enlarging, dissecting pseudoaneurysm. This case illustrates that flow changes from cervical dissections may result in thrombosis of downstream saccular aneurysms. With healing, these aneurysms may recanalize and be misidentified as enlarging dissecting pseudoaneurysms. Review of an MRI from the time of the dissection facilitated the conclusion that the aneurysm was a saccular posterior communicating artery aneurysm, influencing treatment approach.

    1985-08-01

    The combination of a pulmonary scintigram using radioactively labeled albumin macroaggregates (MAA) and a study of the circulation in the bronchial artery was performed in one patient. This noninvasive methodology showed that there was increased circulation to the vascular territory of the lung in which the pulmonary artery was missing. This could have resulted from abnormal communications between the bronchial artery and the pulmonary vessels or an increased blood supply to the right lung from bronchial arteries arising from the aorta. The absence of pulmonary circulation in the right lung was proved by the absence of radioactivity in the right lung after an intravenous injection of labeled albumin MAA.

    Skin and muscles biopsy specimens of a patient harboring A3243G mutation in mitochondrial DNA, with dissection of internal carotid and vertebral arteries, associated with MELAS were studied using histochemical and electron-microscopy techniques. Ragged red fibers, regional variability of SDH histochemical reaction, two types of morphologically atypical mitochondria and their aggregation were found in muscle. There was correlation between SDH histochemical staining and number of mitochondria revealed by electron microscopy in muscle tissue. Similar mitochondrial abnormality, their distribution and cell lesions followed by extra-cellular matrix mineralization were found in the blood vessel walls. In line with generalization of cytopathy process caused by gene mutation it can be supposed that changes found in skin and muscle microvessels also exist in large cerebral vessels causing the vessel wall "weakness", predisposing them to dissection.

    We herein report a case involving a 70-year-old man who was diagnosed with early gastric cancer that occurred after coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA) for effort-induced angina. He was successfully treated by laparoscopic surgery. Preoperative cardiac three-dimensional computed tomography and coronary angiography showed an occlusion of the RGEA graft, which could lead to ligation of the RGEA to dissect the lymph nodes along the RGEA. The laparoscopic approach helps to identify and avoid injury to the RGEA graft because of its enlarged and precise viewing field compared with laparotomy followed by retractor placement. Laparoscopic surgery is a useful method in such cases to reduce perioperative complications risk.

    Acute aortic dissection is a life-threatening condition mainly caused by hypertension, atherosclerotic disease and other degenerative diseases of the connective tissue of the aortic wall. Mesothelial/monocytic incidental cardiac excrescences (cardiac MICE) is a rare benign reactive tumor-like lesion composed of admixture of histiocytes, mesothelial cells, and inflammatory cells set within a fibrinous meshwork without a vascular network or supporting stroma. Cardiac MICE occurring in association with aortic dissection is exceptionally rare (only one such case reported to date). We herein report on the surgical repair of two Stanford type A aortic dissections caused by idiopathic giant cell aortitis in a 66-year-old-woman and by atherosclerotic disease in a 58-year-old-man, respectively. In both cases, the dissections could be visualized via computed tomography. Histopathology showed cardiac incidental MICE within the external aortic wall near the pericardial surface which was confirmed by immunohistochemistry. PMID:26097568

    Giovanni Boccaccio's Decameron contains a novella that details the sudden death of a young man called Gabriotto, including a portrayal of the discomfort that the protagonist experienced and a rudimentary autopsy performed by local physicians. The intriguing description of symptoms and pathologies has made it possible to read a 7-century-old case through the modern clinical lens. Thanks to the medical and philological analysis of the text-despite the vast difference between modern and medieval medicine-2 hypothetical diagnoses have emerged: either an aortic dissection or an atrial myxoma.

    Full Text Available OBJECTIVE: We analyzed the frequency of peripheral embolisms, the underlying heart disease,triggering factors, the sites of the emboli, and evolution of the patients. METHODS: We analyzed 29 cases of peripheral arterial embolism out of a total of 20,211 hospitalizations in a cardiology center in the city of São Paulo. The age was 51.89±18.66 years, and 15 were males. RESULTS: Embolism in the right lower limb occurred in 18 patients (62.0%,in the left lower 11(37.9% and right upper 3 (10.3% limbs, and in the left arm (1. Four patients had embolism in two limbs. The heart disease, mitral valvar heart disease (9 patients - 31.0%; infective endocarditis (7- 24.1%; dilated cardiomyopathy (6 - 20.6%; ischemic coronary heart disease (6 patients - 20.6%; and one patient with cor pulmonale. Atrial fibrillation was observed in 20 patients (68.9%, chronic in 12 patients (41.3% and acute in 8 (27.5%. All patients with mitral valvar heart disease had atrial fibrillation, chronic in 8 patients (88.8%; patients with cardiomyopathy and coronary heart disease, 4 in each group had atrial fibrillation, acute in 60% of the patients.Patients with infective endocarditis, 3 had staphylococcus and 2 Gram-negative bacteria. In the follow-up, 2 patients (6.8% required limbs amputation, and 5 (17.2% died due to embolism. CONCLUSION: Most of the time, embolism does not cause permanent complications. Our data highlight the importance of anticoagulation for patients acute atrial fibrillation in myocardial dysfunction and for patients with chronic atrial fibrillation in cases of mitral valvar heart disease to prevent peripheral embolism.

    Perirenal hematoma after a renal biopsy is a common complication that usually resolves spontaneously, but this rarely requires transfusions or surgical/radiological intervention. We report here on a case of a renal perforating artery that was mistaken for renal arterial bleeding in a 53-year-old woman who was complicated with perirenal hematoma after undergoing a percutaneous renal biopsy. On the color and pulsed wave Doppler ultrasonography, linear blood flow was seen in the perirenal hematoma, which extended perpendicularly from the renal parenchyma into the perirenal space, and this linear blood flow exhibited an arterial pulse wave. On CT angiography, the renal perforating artery was demonstrated as a curvilinear vessel coursing tangentially to the renal margin and we decided that it was a pseudolesion caused by the renal perforating artery. A renal perforating artery may be mistaken for renal arterial bleeding after a percutaneous renal biopsy. A renal perforating artery and arterial bleeding can be differentiated by the location and shape seen on a color Doppler examination and the pulse waves characteristics

    Full Text Available Coronary artery anomalies are rare, with their incidence varying from 1 to 5%. Angiography is a commonly used modality for the assessment of coronary artery anomalies. Based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. Coronary artery anomalies may cause myocardial ischemia secondary to atherosclerosis in the same artery. We present a rare case of duplicated right coronary artery with a separate ostium, which caused myocardial ischemia. Our patient was a 51-year-old diabetic woman with typical chest pain and dyspnea on exertion. Electrocardiography showed left axis deviation, poor R progression, and biphasic T wave in the precordial leads. Echocardiography revealed left ventricular ejection fraction of 30-35% and global hypokinesia. Coronary angiography demonstrated three-vessel disease and a double ostial right coronary artery. We recommended coronary artery bypass graft surgery, but the patient refused it and we continued her treatment with anti-ischemic drugs.

    Congenital coronary artery fistula is an uncommon heart anomaly involving the coronary arteries. We report here a case of a 4-year-old boy who had a coronary fistula from the right coronary artery to the right ventricle, with a coronary aneurysm. He was asymptomatic, but the calculated ratio of pulmonary blood flow to systemic blood flow was shown to be high [pulmonary flow (Qp)/systemic flow(Qs)=1.78]. The coronary angiography showed that the right coronary artery was dilated beginning at the ostium and had an aneurysm at the acute marginal portion. A large spherical aneurysm approximately 20 mm in diameter was found to have been connected with coronary fistula opening into the right ventricle. Surgical repair by closure of the fistula under direct vision, partial resection and suture closure of the aneurysm was performed. Plication of the proximal portion of the right coronary artery was not performed, and the diffusely dilated artery was left untouched. After this operation, he recovered well under anticoagulant treatment with warfarin and aspirin. Postoperative angiography was performed 17 months after the surgery to evaluate morphological changes in the coronary artery. The angiography confirmed the closure of the fistula and the regression of coronary artery dilatation.

    Background Vascular diseases are the principal causes of death and disability in people with diabetes. At the same time, studies suggest a protective role of diabetes in the development of abdominal aortic aneurysms. We sought to determine whether diabetes is associated with decreased hospitalization due to thoracic aortic aneurysms and dissections (TAAD). Methods and Results We used the 2006 and 2007 Nationwide Inpatient Sample (NIS) to determine TAAD discharge rates. Control subjects were randomly selected to achieve three controls per case. Predictor variables in multilevel logistic regression included age, race, median income, diabetes, and hypertension. We estimated that the average rate of hospital discharge for TAAD among individuals diagnosed with diabetes was 9.7 per 10 000, compared to 15.6 per 10 000 among all discharges. The prevalence of diabetes was substantially lower in TAAD (13%) than in control (22%) records. After adjustment for demographic characteristics, the negative association between diabetes and TAAD remained highly significant in both NIS datasets. Compared to discharges without diabetes, those with chronic complications of diabetes were least likely to be diagnosed with TAAD (OR [odds ratio] 0.17, 95% CI, 0.12–0.23). A significant association remained between uncomplicated diabetes and TAAD. We replicated these findings in an independent group of patients who were hospitalized with acute thoracic aortic dissections. Conclusions The principal implication of our findings is that diabetes is independently associated with a decreased rate of hospitalization due to TAAD in proportion to the severity of diabetic complications. Future studies should consider diabetes in predictive models of aneurysm expansion or dissection. (J Am Heart Assoc. 2012;1:jah3-e000323 doi: 10.1161/JAHA.111.000323.) PMID:23130125

Sua incidência é subestimada, e as opções terapêuticas são ainda limitadas. O aparecimento de uma dor torácica aguda ou nova, choque cardiogênico ou morte súbita em pacientes portadores de hipertensão pulmonar deve alertar para o diagnóstico de dissecção da artéria pulmonar.Pulmonary artery dissection is a fatal complication of long-standing pulmonary hypertension, manifesting as acute, stabbing chest pain, progressive dyspnea, cardiogenic shock, or sudden death. Its incidence has been underestimated, and therapeutic options are still scarce. In patients with pulmonary hypertension, new chest pain, acute chest pain, or cardiogenic shock should raise the suspicion of pulmonary artery dissection, which can result in sudden death.

    Full Text Available Abstract Background Previously proposed classifications for carotid plaque and cerebral parenchymal hemorrhages are used to estimate the age of hematoma according to its signal intensities on T1w and T2w MR images. Using these classifications, we systematically investigated the value of cardiovascular magnetic resonance (CMR in determining the age of vessel wall hematoma (VWH in patients with spontaneous cervical artery dissection (sCAD. Methods 35 consecutive patients (mean age 43.6 ± 9.8 years with sCAD received a cervical multi-sequence 3T CMR with fat-saturated black-blood T1w-, T2w- and TOF images. Age of sCAD was defined as time between onset of symptoms (stroke, TIA or Horner's syndrome and the CMR scan. VWH were categorized into hyperacute, acute, early subacute, late subacute and chronic based on their signal intensities on T1w- and T2w images. Results The mean age of sCAD was 2.0, 5.8, 15.7 and 58.7 days in patients with acute, early subacute, late subacute and chronic VWH as classified by CMR (p Conclusions Signal intensities of VWH in sCAD vary over time and multi-sequence CMR can help to determine the age of an arterial dissection. Furthermore, findings of this study suggest that the time course of carotid hematomas differs from that of cerebral hematomas.

    The sural nerve is a small sensory nerve innervating the lateral aspect of the ankle and foot. Clinical symptoms of pathology may present as atypical sensory changes in this region. We present the normal anatomy and ultrasound technique for examination of the sural nerve based on an anatomical dissection, as well as imaging in a normal volunteer. We also present a case series (n = 10) of different conditions of the sural nerve that we encountered based on a review of interesting cases from 4 institutions. The pathological conditions included neuropathy related to stripping or venous laser surgery, compression by abscess, Lyme disease, nerve tumors, traumatic transsection, and encasement by fibrous plaque and edema. Ultrasound with its exquisite resolution is the preferred imaging method for examining the sural nerve in patients with unexplained sensory changes at the lateral aspect of the ankle and foot.

    Systemic cholesterol embolism is a rare complication of atherosclerosis, and has various presentations. Arterial catheterisms are a common cause. However, the association with an aortic dissection has been exceptionally reported. We report the observation of a 70 year-old man, with coronary artery disease, hypertension, diabetes and dyslipidemia. Six months before hospitalization, a coronary angioplasty was performed due to recurrent angina. The association of purpuric lesions on the feet, with acute renal failure confirmed cholesterol embolism syndrome. Transoesophageal echocardiography showed a dissection of the descending thoracic aorta associated with complex atheroma. The evolution was marked by the pulpar necrosis of a toe and by a worsening of the renal failure, requiring definitive hemodialysis. Further echographic control highlighted the rupture of the intimal veil of the dissection. Cholesterol embolism syndrome may reveal an aortic dissection in patients without thoracic symptoms. In such cases, transoesophageal echocardiography is a useful and non-invasive examination.

    A 47-year-old man presented with a rare aneurysm arising from the posterior inferior cerebellar artery communicating artery (PICA com A), manifesting as subarachnoid with intraventricular hemorrhage. Cerebral angiography showed a defect of the left PICA, and the left PICA region was supplied by a communicating artery formed by the fusion of branches from the right PICA and right vertebral artery. Aneurysms arose in the communicating artery, and a small, unruptured fusiform aneurysm was observed adjacent to a ruptured aneurysm. Trapping was performed for the 2 aneurysms with occipital artery (OA)-PICA bypass. Six cases of aneurysms occurring in this vessel including ours have been reported, and hemodynamic factors and congenital fragility of the arterial wall have been suggested as causative factors. Ours is the first case in which a ruptured aneurysm of this vessel was treated surgically with concurrent vascular reconstruction. If the aneurysm has a shape that is difficult to clip, the affected vessel is difficult to preserve, and collateral blood flow to the affected PICA region is considered insufficient, trapping with OA-PICA bypass is recommended.

    Full Text Available Arc of Riolan is a collateral channel that connects the proximal superior mesenteric artery (SMA or its middle colic branch and the proximal inferior mesenteric artery or its left colic branch in case of stenosis of either of the arteries. A 65-year-old diabetic female presented with vague abdominal pain. Ultrasonography showed a large aneurysm within the abdomen in the left lumbar region. Computed tomography (CT angiography done showed severe diffuse atherosclerotic calcification of the abdominal aorta with complete occlusion of the celiac trunk and mild stenosis of SMA origin. The arc of Riolan was seen between the middle colic artery and the ascending branch of the left colic artery, with a large saccular aneurysm in its mid section. No evidence of rupture or hematoma was visible. Another saccular aneurysm was also seen involving the gastro-duodenal and the pancreatico-duodenal collateral arcade. As far as we know, this is the first case of arc of Riolan artery aneurysm to be reported in English literature.

    Full Text Available Chyloperitoneum is the accumulation of lymphatic fluid in the peritoneal cavity. Chylous ascites can occur if it is not recognized during surgery. The incidence of chylous ascites after oncological surgery was approximately 7.4% however, the incidence of lymphorrhea after radical gastrectomy for gastric cancer is so low. Extensive lymph node dissection leads to a higher incidence of lymphorrhea. There have been few cases associated with D1 dissection In most patients conservative treatment is recommended that includes paracentesis, total parenteral nutrition (TPN, a medium chain triglyceride (MCT based diet, and somatostatin. Surgery is the last choice only when conservative treatment fails. In this case we aimed to present a late onset of chylous ascites after subtotal gastrectomy and D1+ dissection that was treated with percutaneous drainage and conservative management.

    2011-01-01

    Endoscopic submucosal dissection (ESDD) is a widely accepted treatment for early gastric cancer (EGC), especially in Korea and Japan. The criteria for the therapeutic use of ESDD for EGC have been expanded recently. However, attention should be drawn to the technical feasibility of the ESDD treatment which depends on a lesion's location, size or fibrosis level, or operator's experience. In the case of a lesion with a high level of difficulty, a more experienced operator is required. Thus, the treatment for a lesion with a high level of difficulty should be performed according to the degree of the operator's experience. In this paper, the authors describe the ESDD procedure for lesions with a high level of difficulty.

    Nutcracker phenomenon or renal vein entrapment is classically seen as a compression of renal vein in between abdominal aorta and superior mesenteric artery with patients being asymptomatic or clinically manifested in the form of nutcracker syndrome as proteinuria, hematuria, flank pain, pelvic congestion in women, and varicocele in men. In this report, we are presenting a case of rare variant of nutcracker phenomenon along with brief review of anatomy, pathophysiology, public health, and clinical significance of nutcracker syndrome. On a routine dissection of an adult male cadaver, we noticed an unusual arrangement of the structures at the hilum of the left kidney showing entrapment of renal vein between left anterior inferior and posterior segmental renal arteries. The variation in the course of left anterior inferior segmental renal artery leads to compression of left renal vein at renal hilum. Therefore, we have named this rare abnormal anatomical entity as hilar nutcracker phenomenon. The structures in the right renal hilum are normal. The objective of this paper is to report an unusual but important variant of nutcracker phenomenon and also give collective knowledge of such anatomical variations in renal vasculature that will help in diagnosing and treating such rare renal disorder.

    Full Text Available Pancreas is an important digestive gland in our body with wide range of both exocrine and endocrine functions. Pancreas has a rich vascular supply from the celiac axis and superior mesenteric artery. The superior pancreatico-duodenal artery (from gastro-duodenal artery and the inferior pancreatico-duodenal artery (from superior mesenteric artery runs in the groove between the pancreas and the duodenum to supply the head of pancreas. Pancreas also derives its blood supply from splenic artery which supplies its head, body and tail region. Profuse vascular supply makes it prone for haemorrhage and that may be the reason that pancreatic blood supply has always been an area of constant interest. In depth knowledge of the variations of blood vessels in this region is utmost important for the successful accomplishment of complex surgical procedures like resection of head of pancreas. The present case report brings in light abnormal pattern of vascularisation in the head region of pancreas and an unusual pancreatic branch from the junction of superior and inferior pancreatic arteries.

    Full Text Available Introduction & objective: One of the most important drawbacks of radial artery is its tendency toward spasm and one of the rare etiologies of that is recurrent blood sampling of the artery. Other causes are injection of drugs in artery in spite of vein, or using radial artery in cardiopulmonary bypass. Papaverine is a useful drug in vasospasm, but it must be used with special caution to avoid it's complications such as arrhythmia. Case: The patient was a 72 year old man with intestinal gangrene and peritonitis whom was operated in Al-Zahra hospital in 2008. During Laparatomy surgery, because of severe acidosis, blood sampling was done 3 times for blood gas analysis. After being taken to the recovery ward, no radial pulse was detectable in the patient's right hand and severe cyanosis in the same hand was seen. After inserting the arterial catheter in brachial artery, treatment with Papaverine, indications of recovery were seen. Conclusion: Despite the rarity of radial artery spasm during anesthesia, it is very dangerous situation, and anesthesiologist must try to prohibit and be able to manage this problem and have suitable drugs in the operation room.

    The present report describes a rare case in which the left gastric artery arises directly from the abdominal aorta and the right hepatic artery from the superior mesenteric artery, as observed during the dissection of a female cadaver. The left gastric artery usually rises as one of the three branches of the celiac trunk, which was originally described by Haller in 1756, whereas the right hepatic artery usually originates from the proper hepatic artery. The knowledge of the typical anatomy of the abdominal arteries, and their variations, is especially important due to the numerous interventions performed in the abdominal area.

    Tinea capitis in postpubertal patients is unusual and may be misdiagnosed as dissecting cellulitis. We report a case of a healthy 19-year-old Hispanic male presenting with a 2-month history of a large, painful subcutaneous boggy plaque on the scalp with patchy alopecia, erythematous papules, cysts and pustules. Although initially diagnosed as dissecting cellulitis, potassium hydroxide evaluation (KOH preparation) of the hair from the affected region was positive. A punch biopsy of the scalp demonstrated endothrix consistent with tinea capitis, but with a brisk, deep mixed inflammatory infiltrate as can be seen with chronic dissecting cellulitis. Fungal culture revealed Trichophyton tonsurans, and a diagnosis of inflammatory tinea capitis was made. The patient was treated over the course of 17 months with multiple systemic and topical antifungal medications, with slow, but demonstrable clinical and histopathological improvement. A rare diagnosis in adults, clinicians should have a high index of suspicion for this condition in an adult with an inflammatory scalp disorder not classic for dissecting cellulitis or with a recalcitrant dissecting cellulitis. Prompt, appropriate diagnosis and treatment is necessary to prevent the long-term complications of scarring alopecia.

    Full Text Available We would like to present a case of branch retinal artery occlusion following uneventful phacoemulsification, possibly caused by sub-Tenon's anaesthesia. There were no predisposing general health problems. There are two possible mechanisms: (1 mechanical effect of the bolus anaesthetic; (2 pharmacologically mediated changes in the vascular calibre. The latter mechanism is much more probable, because of the vasoconstrictive properties of both medications used. This is the first reported case of branch retinal artery occlusion after sub-Tenon's anaesthesia with preservative-free medications.

    Full Text Available During routine dissection in our department, multiple arterial variations were observed in a cadaver. The following arterial variations are present. They are, superficial brachioulnar artery, which originated at the level of junction of upper and middle th ird of arm. It runs a superficial course anterior to median nerve in the arm and terminates in the formation of superficial palmar arch. The brachial artery terminated as radial and common interosseous artery. Subscapular artery and circumflex humeral arte ry arose as a common trunk from the third part of axillary artery. The circumflex humeral artery later divides into anterior circumflex humeral and posterior circumflex humeral arteries. The right common carotid artery bifurcated into internal carotid arte ry anteromedially and external carotid artery posterolaterally at the level of upper lamin a of th yroid cartilage. A proper knowledge of variations in the arterial pattern is a must for a good treatment outcome, especially in the fields like vascular surge ry, reconstructive surgery, cardiac surgery, angiogram, arterial cannulation, arterio - venous fistula for renal dialysis. etc.

    Full Text Available Subclavian arterial injury is rare and potentially life-threatening, particularly when it leads to arterial occlusion, causing limb ischemia, retrograde thromboembolization and cerebral infarction within hours after injury. Here we report a blunt trauma case with subclavian arterial injury, upper extremity ischemia, and the need for urgent treatment to salvage the limb and prevent cerebral infarction. A 41-year-old man had a left, open, mid-shaft clavicle fracture and left subclavian artery injury accompanied by a weak pulse in the left radial artery, decreased blood pressure of the left arm compared to the right, and left hand numbness. Urgent debridement and irrigation of the open clavicle fracture was followed by angiography for the subclavian artery injury. The left distal subclavian artery had a segmental dissection with a thrombus. Urgent endovascular treatment using a self-expanding nitinol stent successfully restored the blood flow and blood pressure to the left upper extremity. Endovascular treatment is a viable option for cases of subclavian artery injury where there is a risk of extremity ischemia and cerebral infarction.

    Full Text Available Background. Rupture of a splenic artery aneurysm is rare complication of pregnancy that is associated with a significant maternal and fetal mortality. Case. A multiparous female presented in the third trimester with hypotension, tachycardia, and altered mental status. A ruptured splenic artery aneurysm was discovered at the time of laparotomy and cesarean delivery. The patient made a full recovery following resection of the aneurysm. The neonate survived but suffered severe neurologic impairment. Conclusion. The diagnosis of ruptured splenic artery aneurysm should be considered in a pregnant woman presenting with signs of intra-abdominal hemorrhage. Early intervention by a multidisciplinary surgical team is key to preserving the life of the mother and fetus.

    Aneurysms of the splenic artery are the most common splanchnic aneurysms. Aneurysms of a splenic artery with an anomalous origin from the superior mesenteric artery are however rare, with eight previously reported cases. Their indications for treatment are superposable to those of aneurysms affecting an orthotopic artery. Methods of treatment of this condition include endovascular, minimally invasive techniques and surgical resection. We report one more case of aneurysm of an aberrant splenic artery, treated with surgical resection, and preservation of the spleen.

    Full Text Available Abstract Introduction This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm. Case presentation A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery. Conclusion This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer.

    2016-01-01

    A young otherwise healthy 27-year-old male who has been using anabolic steroids for a long time developed Type I aortic dissection associated with heavy weightlifting. The patient did not have a recent history of trauma to the chest, no history of hypertension, and no illicit drug use. He presented with severe chest pain radiating to back and syncopal event with exertion. Initial vitals were significant for blood pressure of 80/50 mmHg, pulse of 80 beats per minute, respirations of 24 per minute, and oxygen saturation of 92% on room air. Physical exam was significant for elevated jugular venous pressure, muffled heart sounds, and cold extremities with diminished pulses in upper and absent pulses in lower extremities. Bedside echocardiogram showed aortic root dilatation and cardiac tamponade. STAT computed tomography (CT) scan of chest revealed dissection of ascending aorta. Cardiothoracic surgery was consulted and patient underwent successful repair of ascending aorta. Hemodynamic stress of weightlifting can predispose to aortic dissection. Aortic dissection is a rare but often catastrophic condition if not diagnosed and managed acutely. Although rare, aortic dissection needs to be in the differential when a young weightlifter presents with chest pain as a delay in diagnosis may be fatal. PMID:27738530

    Full Text Available Salivary gland tumors comprise of less than 3% of all tumors of the head and neck region. Pleomorphic adenoma represents 45 to 74% of all these salivary gland tumors and 65% of them occur in the parotid gland. Owing to the close proximity of this tumor to the facial nerve, there have been various techniques for surgical management of this tumor in the literature. Extracapsular dissection of pleomorphic adenoma is a conservative treatment modality which spares the handling of facial nerve. We are reporting a case of extracapsular dissection of pleomorphic adenoma in the lower pole of the superfi cial lobe of the parotid gland in a 22 year-old Indian male with a 1-year follow-up.

    Thrombosis of the basilar artery is not a rare disease, and the mortality is reported to be 60 to 80%. Present standard therapy with heparin infusions yields poor results. The high risk of intracerebral haemorrhage prohibits systemic fibrinolytic therapy. Due to these facts and good experience in our department with the use of local intracoronary lysis in acute myocardial infarction, the method of local thrombolysis was applied in a case of acute basiliar artery thrombosis. Fibrinolytic therapy was started via an angiography catheter placed in the vertebral artery in a 28 year-old woman with hemiplegia and severe brain stem symptoms. The patient received 200,000 IU streptokinase within 2 hours and subsequently 300,000 IU urokinase within 10 hours. The vessel re-opened completely. The neurological symptoms decreased during the following weeks. Based on this experience and according to rare reports in the literature we believe local low-dose thrombolysis to be a causal therapy promising success for acute thrombosis of the basilar artery. This therapy can be carried out in every medical centre able to perform selective angiography and experienced in the administration of fibrinolytic drugs.

    2015-05-01

    Full Text Available Anastomosis found in the adulthood between the carotid and vertebro - basilar systems, apart from the posterior communicating artery, are extremely infrequent and are due to the persistence of vessels that joined both systems during the fetal period. This carotid - vertebrobasilar anastomosis are the trigeminal, otic, and hypoglossal and proatlantal arteries. P ersistent trigeminal artery is the commonest of the above mentioned four arteries. The reported incidence is about 0.2%. Patients may be asymptomatic or present symptoms due to low flow of posterior circulation or carotid microembolization from posterior circulation. PTA can cause trigemina l neuralgia. We report in this paper a case of a persistant trigeminal artery found in an adult female with a para p com aneurysm who had persistent trigeminal artery which was seen in C T angiogram .

    1988-08-01

    An unusual case of post-irradiation aneurysm of extracranial internal carotid artery is presented. A 70-year-old man, complaining of left cervical throbbing mass with focal pain, was admitted on February 8, 1985. It was noted, from his past history, that he had had surgery of the removal of cervical lymphnodes and that unknown dosage of irradiation had been added to the cervical region 30 years before. Left carotid angiography (on admission) demonstrated a giant aneurysm in the cervical portion of internal carotid artery. Right carotid angiography with compression of left carotid artery revealed good cross filling through anterior communicating artery. Computed tomography with contrast media showed a ring like enhanced mass, which was thought to suggest that a large part of the aneurysm was filled with intraluminal thrombosis. During 30 days of evaluation, the aneurysm grew larger and his cervical pain became untolerable. Operation, the resection of the aneurysm and the reconstruction (of circulation) with vein graft, was challenged on March 12. It was so difficult with meticulous work that the ligation of left common carotid artery was performed after all. Seven days after the operation, he suffered from the gastrointestinal bleeding, which was enough to lead him to hypovolemic shock. Thereafter, right hemiparesis and aphasia were brought about. Two months later, he died of pneumonia. On histological examination, it was demonstrated that the aneurysm communicated with the necrotic tissue and that the normal structure of the blood vessel was not observed in the aneurysmal wall and consisted of the collagenous fiber and granulated tissue. The aneurysm was interpreted as a false one.

    Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare anomaly. It may contribute to myocardial ischemia or sudden death, although the lesion is usually asymptomatic. We report a sudden death case of a 58-year-old man with ARCAPA coexisting with severe atherosclerotic coronary artery disease. He had been healthy until he complained of chest pain, several days before death, despite the discovery of heart murmur in childhood and suspicion of valvular heart disease. The autopsy revealed not only typical findings of the right coronary anomaly with well-developed collateral circulations but also severe atherosclerotic lesions of the left coronary artery, and ischemic change of the myocardium in the left and right coronary arterial perfusion territory. In addition to the "coronary steal" phenomenon primarily caused by ARCAPA, the reduced flow of both coronary arteries and further increase of "coronary steal" due to atherosclerotic obstructive coronary disease might have contributed to the patient's death.

    Full Text Available Abstract Background Acute mesenteric ischemia due to an embolism of the superior mesenteric artery is associated with a high mortality rate. Over 20 percent of acute mesenteric embolism cases consist of multiple emboli, and the long-term prognosis depends on the incidence of subsequent embolic events at other sites. The incidence of emboli in the upper extremity associated with a superior mesenteric arterial embolism has rarely been described. The signs and symptoms of ischemic change in the upper limb can be masked by other circumstances, such as postoperative conditions or complications. In these cases, a late presentation or delayed diagnosis and treatment can result in limb loss. Case presentation We present a rare case of a 67-year-old Japanese woman with atrial fibrillation who developed an embolic occlusion of the brachial artery associated with a superior mesenteric arterial embolism. She developed gangrene in her right hand, which had progressed to the point that amputation was necessary by the time the gastrointestinal surgeon had consulted the Department of Orthopedic Surgery. The brachial arterial embolism diagnosis was delayed by the severe abdominal symptoms and shock conditions that followed the emergency enterectomy, resulting in amputation of the upper limb despite anticoagulation therapy. In this case, multiple infarctions of the spleen were also observed, indicating a shower embolism. Conclusions When treating a superior mesenteric arterial embolism in a patient with atrial fibrillation, the possibility of recurrent or multiple arterial thromboembolic events should be considered, even after the procedure is completed.

    310 cases of glomerulonephritis classified morphologically according to the criteria of the WHO were analyzed retrospectively in order to determine the frequency of arterial hypertension. The overall prevalence of arterial hypertension was 61%. Hypertension was most frequent and severe in membranoproliferative and sclerotic glomerulonephritis, but often mild and transient in extracapillary glomerulonephritis. Hypertension usually developed during the early stages of the disease when kidney function was well preserved and in only 16% was hypertension first seen during the uremic stage. No correlation was found between hypertension and the presence of the nephrotic syndrome. During dialysis, hypertension was present in 78%; in 90% of these patients hypertension was "controllable" and in 10% it was "uncontrollable".

    Full Text Available Objective:Post-tonsillectomy hemorrhage remains an important factor in determining the safety of performing tonsillectomy as a day case procedure. The aim of this study was to determine the safety of day case tonsillectomy by using combination method, cold dissection tonsillectomy and bipolar diathermy hemostasis. Methods:A prospective randomized clinical study conducted on the patients who had undergone day case tonsillectomy (DCT. There were two groups (DCT and control group each group consisting of 150 cases. Tonsillectomy was performed by using combination method; cold dissection and hemostasis was achieved by ligation of vessels with bipolar electerocautery. Findings:We found 3 cases of post-tonsillectomy bleeding in DCT group and 4 cases in the control group. There was no statistically significant difference in the rate of post-operative hemorrhage between the two groups. Conclusion:The findings suggest the safety of the combination of cold dissection tonsillectomy and bipolar diathermy hemostasis as day case tonsillectomy.

    Full Text Available ABSTRACT: The renal vasculature was always a subject of varia tions both in the number and pattern of portal of entry into kidney and Perihilar placement of the artery, vein and pelvis. Good anatomical insight is an essential prerequisite besides the surgical expertise. The cadaveric dissection revealed a Right Kidney supplied by Quadruple renal arteries & Drained by two renal veins. The main renal artery (MRA was arising from antero lateral aspect and the accessory renal artery was arising from anterior as pect of aorta 1cm distal to the former vessel. Only the MRA showed Fork Pattern Branching with fou r anterior segmental arteries and one posterior segmental artery in the pre hilar region. T he first and fourth segmental arteries showed a small subsidiary branch and a large tortuo us subsidiary branch respectively. The later along with the branch running downwards and lateral from lower renal artery formed a common trunk and pierced the capsule and entered int o the substance of the kidney anteriorly about 2cm lateral to the hilum, thus forming an abe rrant artery. The upper polar artery was seen arising from the lower supra renal artery. The main renal vein (MRV, was formed by two formative tributaries of which one is larger and ot her being smaller. The later was seen just anterior to the third anterior segmental branch of MRA. Accessory renal vein was formed by only one tributary encircled by the fourth anterior segmental artery and posterior segmental artery. There was crowding of structures seen with altered hilar anatomy in both vertical and horizontal disposition. Such a rare combination of extra renal multiple arterio-venous variation is of worth concern to the urologists harvesting ki dneys from the live donors for performing transplantation procedures. Partial nephrectomies for the hilar tumors and for Radiologists during interpretation of the angiograms.

    Background Blunt thoracic trauma can rarely result in coronary artery injury. Blunt trauma can result in occlusion of any of the coronary arteries or can lead to its rupture and bleeding. Traumatic coronary artery occlusion can lead to myocardial infarction, while its rupture and bleeding can result in hemopericardium and cardiac tamponade, and can be rapidly fatal. Survival after coronary artery rupture in blunt thoracic trauma is exceedingly rare. Case Presentation We present a case of a yo...

    The incidence of congenital heart disease (CHD) is 2.4-3.8/1000 live births. Up to 70.7 % of all cases of CHD are reported to be benign; complex heart anomalies are extremely rare. Our case is extremely rare, as we report three very rare findings-truncus arteriosus, anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA), and unilateral left pulmonary artery agenesis-in a single patient. Congenital complex cardiac abnormalities are very rare, and two-dimensional echocardiography screening should be supported by cardiac computed tomography (CT). We report a case of truncus arteriosus associated with ARCAPA and left pulmonary artery agenesis diagnosed by cardiac computed tomography; we believe that such an unusual case with all three of these entities has never been reported before.

    Aneurysms of the cervical vertebral artery (VA) are uncommon; they are often caused by trauma or spontaneous dissection. A fusiform aneurysm without evidence of atherosclerosis or dissection has not been reported previously. A 46-year-old man presented with a pontine infarct. Imaging revealed a fusiform aneurysm of the left VA at the C5-6 level, with occlusion of the basilar artery. Associated minor anomalies included fusion of the vertebral bodies of C5 and C6, cervical rib and platybasia. The left VA arose directly from the aortic arch and entered the transverse foramen at the C4 level. Hyperextension and left lateral flexion of the neck caused kinking of the VA proximal to the aneurysm. Turbulent flow in the aneurysm lumen was noted on angiography. (orig.) With 4 figs., 10 refs.

    Intracranial aneurysms in young infants are extremely rare, with few published reports on the etiology, evaluation, treatment strategies, and follow-up of this condition in this population. The authors report the case of a traumatic dissecting aneurysm at the vertebrobasilar junction (VBJ) in a 3-month-old infant caused by nonaccidental trauma. Therapeutic occlusion of the VBJ was contemplated, but coil embolization of the main aneurysm sac proved feasible, and anticoagulation and antiplatelet agents were initiated. The patient made a full neurological recovery, and follow-up studies demonstrated stable aneurysm occlusion. Management and follow-up strategies for this challenging condition are discussed.

    Full Text Available Abstract Background Peripheral nerve injury and brachial plexopathy are known, though rare complications of coronary artery surgery. The ulnar nerve is most frequently affected, whereas radial nerve lesions are much less common accounting for only 3% of such intraoperative injuries. Case presentations Two 52- and 50-year-old men underwent coronary artery surgery. On the first postoperative day they both complained of wrist drop on the left. Neurological examination revealed a paresis of the wrist and finger extensor muscles (0/5, and the brachioradialis (4/5 with hypoaesthesia on the radial aspect of the dorsum of the left hand. Both biceps and triceps reflexes were normoactive, whereas the brachioradialis reflex was diminished on the left. Muscles innervated from the median and ulnar nerve, as well as all muscles above the elbow were unaffected. Electrophysiological studies were performed 3 weeks later, when muscle power of the affected muscles had already begun to improve. Nerve conduction studies and needle electromyography revealed a partial conduction block of the radial nerve along the spiral groove, motor axonal loss distal to the site of the lesion and moderate impairment in recruitment with fibrillation potentials in radial innervated muscles below the elbow and normal findings in triceps and deltoid. Electrophysiology data pointed towards a radial nerve injury in the spiral groove. We assume external compression as the causative factor. The only apparatus attached to the patients' left upper arm was the sternal retractor, used for dissection of the internal mammary artery. Both patients were overweight and lying on the operating table for a considerable time might have caused the compression of their left upper arm on the self retractor's supporting column which was fixed to the table rail 5 cm above the left elbow joint, in the site where the radial nerve is directly apposed to the humerus. Conclusion Although very uncommon, external

    Polyarteritis nodosa (PAN) is a multisystem disease characterized by necrotizing vasculitis of small and medium-sized arteries, and in 50 % of all cases there is gastrointestinal involvement. We describe a patient with PAN involving the gastrointestinal tract. A small bowel series showed nodular fold thickening, submucosal filling defects, shallow ulcerations, segmental luminal narrowing, and decreased peristalsis at the duodenum, jejunum, and ileum; superior mesenteric arteriography showed hypervascularity and microaneurysm. Segmental resection of the small bowel indicated the presence of PAN. (author). 10 refs.,3 figs.

    Full Text Available Primary Pulmonary Hypertension is a rare disease occurring in 1-2 per million population. It is 2-4 times more common in female. Idiopathic or primary pulmonary hypertension is defined as a disorder with no identifiable cause in which resting mean pulmonary artery pressure in adults is above 25 mmHg and 30 mmHg with exercise. Idiopathic or primary pulmonary hypertension is diagnosed after ruling out all the possible secondary causes of pulmonary hypertension. We are presenting a case of middle-aged male who presented with dyspnoea and on further evaluation found to have primary pulmonary hypertension, which is uncommon in male

    A 41-year-old man collapsed after lifting weights at a gym. Following admission to the emergency department, a 64-slice cardiac computed tomography (CT) revealed a Stanford Type A aortic dissection arising from a previous coarctation repair. Multiphasic reconstructions demonstrated an unstable, highly mobile aortic dissection flap that extended proximally to involve the right coronary artery ostium. Our case is an example of the application of electrocardiogram-gated cardiac CT in directly visualizing involvement of the coronary ostia in acute aortic dissection, which may influence surgical management.

    Bilateral coronary artery fistulas originating from both right and left coronary arteries are rare congenital abnormalities. A 58-year-old man presented with chest pain unrelated to exertion. Coronary angiography showed a fistula originating from the level of the first diagonal branch of the left anterior descending (LAD) coronary artery and a 95% stenosis just distal to the fistula. Right coronary angiography showed another fistula originating from the ostium of the right coronary artery. Both fistulas drained into the pulmonary artery. Coronary bypass surgery was performed for the LAD lesion using the left internal mammary artery graft, during which both fistulas were ligated. No complications were encountered postoperatively.

A 48-year-old male patient was admitted to our institution for evaluation of chest pain. The coronary angiography revealed fistulae from left main coronary artery (LMCA and right coronary artery (RCA to the pulmonary artery. We concluded that angina pectoris was caused by a steal phenomenon and the patient was recommended surgical intervention. To our knowledge, this is the first paper reporting three fistulae associated with multiple aneurysms originating from proximal coronary arteries, which were connected to the pulmonary artery.

    Persistent stapedial artery is a rare congenital anomaly that occurs by a failure in the involution of such artery. Most patients with persistent stapedial artery are asymptomatic. The imaging diagnosis is made principally by means of multidetector computed tomography. In the present case, persistent stapedial artery was an incidental computed tomography finding. The authors discuss the embryogenesis, computed tomography findings and the importance of an early diagnosis of such anomaly. (author)

    External iliac artery endofibrosis is a rare medical condition typically encountered in young endurance athletes, mainly cyclists. Iliac endofibrosis usually develops in the external iliac artery and is rarely seen in the common iliac or in common femoral arteries. We describe a unique case of a patient who was not a professional or high-endurance cyclist. The lesions in our case appeared to be bilateral in the common iliac arteries and were not limited to the external iliac artery as most commonly described. We present an overview of the literature regarding this medical condition.

    2016-02-01

    Dissection of the left main coronary artery during coronary artery bypass graft (CABG) surgery is a rare, potentially lethal complication, usually diagnosed at post-mortem. During the cross-clamp period of a 4-vessel coronary artery bypass graft procedure in a 74-year old hypertensive woman, retrograde dissection occurred in a diffusely diseased marginal artery when perfused with cardioplegic solution at a pressure of 140-150 mmHg through a vein graft. The dissection extended back to the left main artery, included the posterior proximal ascending aorta and then down the left anterior descending artery (LAD). Transoesophageal echocardiography (TOE) confirmed the left main dissection and showed anterior-septal-lateral akinesis in a previously normally functioning left ventricle (LV). The circumferentially calcified proximal LAD was grafted with a saphenous vein by carving an oval area of calcium creating an elliptical opening in the artery wall. Normal LV function returned and, in the area of the left main dissection, there was only thickening with no colour flow. Eight months postoperatively cardiac catheterization showed normal LV function, patent vein grafts to the right coronary artery and proximal LAD, left internal mammary artery to distal LAD and an occluded sequential marginal vein graft. Twelve years postoperatively, the patient is well with Class I angina, on medication. There is no previous documentation of a diagnosed and successfully treated left main dissection during CABG surgery. Since this case using the technique of creating an oval opening in a circumferentially calcified coronary artery (with an otherwise satisfactory lumen), the author has been using this technique to bypass otherwise non-bypassable arteries; this technique may be useful to help patients with severe calcific coronary artery disease.

    Arterial hypertensions (HTA) of endocrine origin are a rare cause of hypertension; HTA overall prevalence don't exceed 4% of hypertensive patients. Research interest in endocrine HTA is due to the severity of some life-threatening, potentially curable and reversible forms of HTA. The aim of our study was to determine the clinical, paraclinical, etiological and therapeutic profile of secondary HTA of endocrine origin in patients treated in endocrinology department at the University Hospital Mohamed VI in Marrakech. We conducted a prospective, descriptive study spanned 4 years, enrolling 45 patients with endocrine HTA. The average age was 44.89 years, with a clear predominance of women (sex ratio 0.49). Etiology of endocrine HTA was dominated by pheochromocytoma (17 cases), hypercorticism (11 cases) and acromegaly (8 cases). HTA were paroxysmal in 24.4%. HTA were immediately classified as grade 3 severe in 40% of cases. HTA were complicated by heart disease in 24% of cases and by renal disease in 20% of cases. Curative treatment cleared up HTA in 60% of cases (27 cases). The diagnosis of secondary endocrine HTA is sometimes difficult because of the lack of clinical specificity. It is not unusual for HTA to be the only manifestation of the disease. In our study we noted the paroxysmal and severe nature of HTA. The potentially curable nature of HTA in more than two thirds of cases, demostrates the importance of early diagnosis of each severe HTA resistant to treatment or in the presence of suggestive clinical, biological or radiological signs.

    We report the case of a 45-year-old chronic smoker who presented with acute paraplegia occurring during coitus and subsequently developed acute renal failure (ARF) requiring dialysis. He had absent peripheral pulses in the lower limbs with evidence of acute ischemia. Doppler study showed dissecting aneurysm of thoracic aorta, thrombotic occlusion of the distal aorta from L1 level up to bifurcation and occlusion of the right renal artery by a thrombus that was confirmed by magnetic resonance imaging of the spine. He was not subjected to any vascular intervention as his lower limbs were not salvageable due to delay in the diagnosis. Post-coital aortic dissection and aortic dissection presenting with acute paraplegia and ARF are very rare. This is probably the first case report with post-coital acute aortic dissection presenting with paraplegia and ARF. This case emphasizes the importance of a careful examination of peripheral pulses in patients presenting with ARF and paraplegia.

    Full Text Available Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She was admitted to our clinic with the suspicion of pulmonary artery pathology. Absent perfusion of the left lung with normal ventilation was visualized on scintigraphy. MDCT angiography of pulmonary arteries showed absent left main pulmonary artery with systemic collaterals around left hemithorax. Pulmonary artery agenesis can be asymptomatic and isolated until adulthood. Both scintigraphy and CT angiography images of pulmonary artery agenesis of a patient are rare in the literature. Pulmonary ventilation- perfusion scintigraphy can be used not only for pulmonary embolism but also pathologies involving pulmonary artery and its branches. (MIRT 2012;21:80-83

    Background: Heterotopic gastric mucosa (HGM) is the most reported epithelial heterotopia, but it is very rare in the rectum and anus. Methods: The first case of an asymptomatic adult male with a large nonpolypoid HGM in the low rectum underwent complete resection by endoscopic submucosal dissection (ESD) is reported. The systematic review was based on a comprehensive search of MEDLINE, EMBASE and Google Scholar. Studies on humans were identified with the term ‘heterotopic gastric mucosa in the rectum and /or anus.’ Results: The search identified 79 citations, and 72 cases were evaluated comprising the present report. Congenital malformations were observed in 17 (24%) patients; rectal duplication accounted for most of the cases. The HGM was located in the anus and perineal rectum in 25 cases (41%) and low, middle and proximal pelvic rectum in 20 (33%), five (8%) and 11 cases (18%), respectively. Morphology was nonpolypoid in 37 cases (51%), polypoid in 26 cases (36%) and ulcerated in nine cases (13%). Specific anorectal symptoms were reported by 50 (69%) patients of the whole study population, and by 33 (97%) of 34 patients ≤ 18 years. Complications were observed in 23 cases (32%). The HGM was excised in 50 cases (83%). Endoscopic resection was performed in 17 cases (34%); resection was piecemeal in five of 12 lesions ≥15 mm, required argon plasma coagulation in two cases and was associated with residual tissue in two (17%). Intestinal metaplasia and an adenoma with low-grade dysplasia were described in three adults (4%). Discussion: This systematic review shows that the HGM in the rectum and anus may be associated with specific rectal symptoms and serious complications, mainly in the pediatric population, and a risk of malignancy in adults. Its complete excision should be recommended, and the ESD can overcome the technical limits of conventional endoscopic snare resection and avoid unnecessary surgery. PMID:27103738

Methods Clinical case report with patient’s consent and bibliographic review. Results A 67-year-old male inpatient with recurrent severe psychotic depression was hospitalized and ECT was indicated after failure of the pharmacological treatment. A comprehensive clinical pre-evaluation revealed only nonspecific ST-segment changes in electrocardiogram. During the 7th ECT session, it was observed transitory ST-segment depression followed by a discrete increase of plasma troponin I. Severe tri-vessel coronary artery stenosis was found and a percutaneous coronary angioplasty was performed, with satisfactory psychiatric and cardiac outcomes. Conclusions Unipolar depression (UPD and cardiovascular disease are often coexistent conditions, especially among the elderly. In the current case, myocardial ischemia was detected lately during ECT therapy and its treatment allowed the UPD treatment to be completed adequately.

    Full Text Available Nowadays, only few cases of simultaneous cerebral arterial and venous thrombosis were reported. However, there might be high probability of coexisted cerebral arterial and venous changes. It is worthy to study the reasons and frequency of these coexisted vascular changes contributing to the development of clinical pictures. We analyzed 12 cases of simultaneous cerebral and/or neck vascular changes based on vascular images and ultrasonography which were divided into 4 groups: coexistence of simultaneous arterial and venous thrombosis; venous thrombosis with arterial hypoplasia; arterial thrombosis, arteritis or dissections with venous sinus hypoplasia; coexistence of arterial and venous hypoplasia.

    AIM: To determine the distance between the branching point of the left colic artery (LCA) and the inferior mesenteric artery (IMA) by computed tomography (CT) scanning, for preoperative evaluation before laparoscopic colorectal operation.METHODS: From February 2004 to May 2005, 100patients (63 men, 37 women) underwent angiography performed with a 16-scanner multi-detector row CT unit (Toshiba, Aquilion 16). All images were analyzed on a workstation (AZE Ltd, Virtual Place Advance 300). The distance from the root of the IMA to the bifurcation of the LCA was measured by curved multi-planar reconstruction on a workstation.RESULTS: The IMA could be visualized in all the cases,but the LCA was missing in two patients. The mean distance from the root of the IMA to the root of the LCA was 42.0 mm (range, 23.2-75.0 mm). There were no differences in gender, arterial branching types, body weight, height, and body mass index.CONCLUSION: Volume-rendered 3D-CT is helpful to assess the vascular branching anatomy for laparoscopic surgery.

    Doppler ultrasonography (US) is an effective, inexpensive and widely used modality in renal vascular imaging. Demonstration of a parvus-tardus waveform pattern in renal arteries or intrarenal segmental arteries with Doppler US indicates a significant proximal stenosis. In the presence of a parvus-tardus pattern in both renal arteries, bilateral renal artery stenosis or a stenosis more proximal to the renal arteries should be considered.{sup 1} We present such a case and describe the Doppler ultrasonographic findings that suggested coarctation of the aorta.

    Full Text Available Objective This study aimed to assess the clinicoradiological features and treatment outcome of intracranial dissecting aneurysms (IDAs in childhood.Methods We conducted a retrospective study of pediatric patients who were treated for spontaneous IDAs in our institute between January 2010 and December 2015. The clinical presentation, aneurysm characteristics, treatment modality, and outcome were studied. Results We studied 26 pediatric patients (mean age, 13.4 years; range, 4–18 years with 31 IDAs who comprised 6.9% of all IDA patients treated during the same period. Seventeen (65.4% patients were male and nine (34.6% were female. The incidence of large (≥10mm in size or giant aneurysms (≥25mm in size was 65.5%. Twenty-one (80.8% patients underwent endovascular or surgical treatment and five (19.2% received conservative treatment. Perioperative complications occurred in three patients, in whom two eventually recovered completely with a Glasgow Outcome Scale (GOS score of 5 and one partially recovered with a GOS score 4. Overall, 25 (96.2% patients had a favorable outcome and one (3.8% had an unfavorable outcome at a mean follow-up of 22.8 months (range, 6–60 months.Conclusions Pediatric IDAs are rare. In this series, endovascular management was a relatively safe and effective method of treatment for pediatric IDAs. However, continued follow-up is required because of the possibility of aneurysm recurrence and de novo aneurysm formation after treatment.

    Full Text Available Introduction. Some cases with aortic dissection (AD could present with various complaints other than pain, especially neurological and cardiovascular manifestations. AD involving the carotid arteries could be associated with many clinical presentations, ranging from stroke to nonspecific headache. Case Report. A 71-year-old woman was admitted to emergency department with vertigo which started within the previous one hour and progressed with deterioration of consciousness following speech disorder. On arrival, she was disoriented and uncooperative. Diffusion magnetic resonance imaging (MRI of brain was consistent with acute ischemia in the cerebral hemisphere. Fibrinolytic treatment has been planned since symptoms started within two hours. Echocardiography has shown the dilatation of ascending aorta with a suspicion of flap. Computed tomography (CT angiography has been applied and intimal flap has been detected which was consistent with aortic dissection, intramural hematoma of which was reaching from aortic arch to bilateral common carotid artery. Thereafter, treatment strategy has completely changed and surgical invention has been done. Conclusion. In patients who are admitted to the emergency department with the loss of consciousness and stroke, inadequacy of anamnesis and carotid artery involvement of aortic dissection should be kept in mind.

    2014-01-01

    Full Text Available Background. An adequate blood flow is directly related to graft survival in living donor liver transplantation. However, in some cases, unfavorable conditions prevent the use of the hepatic artery for arterial reconstruction. Herein, we report a case in which the recipient right gastroepiploic artery was used as an option for arterial reconstruction in adult-to-adult living donor liver transplantation. Case Report. A 62-year-old woman, with cirrhosis due to hepatitis B associated with hepatocellular carcinoma, was submitted to living donor liver transplantation. During surgery, thrombosis of the hepatic artery with intimal dissection until the celiac trunk was observed, which precluded its use in arterial reconstruction. We decided to use the right gastroepiploic artery for arterial revascularization of the liver graft. Despite the discrepancy in size between donor hepatic artery and recipient right gastroepiploic artery, anastomosis was performed successfully. Conclusions. The use of the right gastroepiploic artery as an alternative for arterial revascularization of the liver graft in living donor liver transplantation should always be considered when the hepatic artery of the recipient cannot be used. For performing this type of procedure, familiarity with microsurgical techniques by the surgical team is necessary.

    We describe the case of a young female patient who sustained a radial artery penetration injury from broken glass after falling and was managed only by external compression without arterial repair. Although the patient did not have any reported predisposing factors and the radial artery was normal as well as patent in the angiographic examination, she developed progressive multiple digital ischemia and required subsequent amputation of the gangrenous fingers. The possible mechanism might be an occlusion of the digital arteries originating from the injured radial artery by dispersion of thrombembolic particles distally during the injury as there was sparing of involvement of the ring finger, which wore a ring that restricted the thromboembolic particles from passing distally during the accident. This case revealed that particular attention should be paid to those patients with a radial artery penetration injury to facilitate early detection and implementation of therapy for possible finger ischemia and subsequent gangrene.

    The traditional treatment of splenic artery aneurysm (SAA) is generally surgery and/or transcatheter arterial embolization, but recently, the treatment of SAA using a stent graft has been reported. However, the acute angle of the celiac axis, as well as the tortuous path of the splenic artery makes the use of stent graft difficult for treatment of aneurysma. We report here a case of SAA treated with the technique of double overlapping metallic stents.

    Full Text Available Abstract Introduction Although variations in the origin of the testicular artery are not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. We discuss the case of a high origin of the testicular artery, its embryology, classification systems, and its clinical significance. Case presentation We report a very rare case of high origin of the left testicular artery in a 68-year-old Caucasian male cadaver. The artery originated from the anterolateral aspect of the abdominal aorta, 2 cm cranially to the ipsilateral renal artery. Approximately 1 cm after its origin, it branched off into the inferior suprarenal artery. During its course, the artery crossed anterior to the left renal artery. Conclusions A knowledge of the variant origin of the testicular artery is important during renal and testicular surgery. The origin and course must be carefully identified in order to preserve normal blood circulation and prevent testicular atrophy. A reduction in gonadal blood flow may lead to varicocele under circumstances. A knowledge of this variant anatomy may be of interest to radiologists and helpful in avoiding diagnostic errors.

    Gestational choriocarcinoma is easily disseminated hematogenously and its hypervascular nature places the patient at risk of significant hemorrhage both at the sites of metastatic lesion and in the uterus. In addition, its tends to give rise to pseudoaneurysm formation. Treatment of the condition by percutaneous embolization has been reported in several published articles, and hemoperitoneum secondary to rupture of splenic metastasis of gestational choriocarcinoma has also been reported, as has angiographic embolization. Hemoptysis resulting from pulmonary metastasis and treatment by means of embolization of the bronchial artery have not been reported, however. In this article, we describe a case of hemoptysis and hemoperitoneum due to pulmonary and splenic metastasis of gestational choriocarcinoma. Treatment of the condition involved embolization of the bronchial artery and superselective embolization of the splenic artery.

    Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver). After the trumpet maneuver, the pharyngeal mucosa was stretched out. The pedicle of the tumor arose from the left-anterior wall of the pharyngoesophageal junction, so we decided to perform endoscopic resection. Result. Under general anesthesia, the curved laryngoscope made it possible to view the whole hypopharynx, including the apex of the piriform sinus and the orifice of the esophagus. The cervical esophageal cancer was pulled up to the hypopharynx. Under collaboration between a head and neck surgeon and an endoscopist, the tumor was resected en bloc by endoscopic laryngopharyngeal surgery combined with endoscopic submucosal dissection. Conclusion. Transnasal endoscopy using the trumpet maneuver is useful for a precise diagnosis of the pharyngoesophageal junction. Close collaboration between head and neck surgeons and endoscopists can provide good results in treating tumors of the pharyngoesophageal junction. PMID:28154766

    Full Text Available Abstract Introduction Unilateral absence of the pulmonary artery (UAPA or pulmonary artery agenesis is a rare congenital disorder presenting with a wide spectrum of symptoms. The clinical presentation is variable and many patients can be asymptomatic for many years and even throughout their lives. Case presentation We report the case of a 53-year-old African-American woman who was diagnosed with right pulmonary artery agenesis after presenting with uncontrolled asthma and recurrent bronchopulmonary infections. Conclusion In an unexplained case of recurrent respiratory infections and shortness of breath, the possibility of a rare congenital anomaly like UAPA should be considered and an appropriate evaluation should be done.

  13. A rare case of persistent hypoglossal artery associated with contralateral proximal subclavian stenosis

    Directory of Open Access Journals (Sweden)

    Romeo Antonio

    2016-01-01

    Full Text Available The persistent hypoglossal artery is rare vascular anomalies. We report the case of a 50-year old man with right hypoglossal artery, ipsilateral hypoplasic internal carotid artery, associated with left proximal subclavian stenosis with subclavian steal syndrome. Power-Doppler-Ultra-Sonography spectral images obtained after the patient exercised the left arm showed mid-systolic deceleration with retrograde late-systolic velocities. A Computed Tomography Angiography demonstrated a proximal stenosis of the left SA, a mild right ICA hypoplasia and an anomalous artery arising from right ICA at C2–C3 level, entering the cranium via the hypoglossal canal and joining the basilar artery. Usually the presence of PHA may be completely asymptomatic, and detected as an incidental finding by CTA or MRA, but in our case its diagnosis is extremely important because it is often the only vessel supplying blood to the basilar trunk and posterior circulation.

    Full Text Available Abstract Introduction Giant cell arteritis is an emergency requiring prompt diagnosis and treatment. Superficial temporal artery biopsy is the gold diagnostic standard. Complications are few and infrequent; however, facial nerve injury has been reported, leaving an untoward cosmetic outcome. This case report is to the best of our knowledge only the fourth one presented in the available literature so far regarding facial nerve injury from superficial temporal artery biopsy. Case presentation A 73-year-old Caucasian woman presented for neurological evaluation regarding eyebrow and facial asymmetry after a superficial temporal artery biopsy for presumptive giant cell arteritis-induced cephalalgia. Conclusion Damage to branches of the facial nerve may occur after superficial temporal artery biopsy, resulting in eyebrow droop. Although an uncommon and sparsely reported complication, all clinicians of various specialties involved in the care of these patients should be aware of this given the gravity of giant cell arteritis and the widespread use of temporal artery biopsy.

    2014-08-01

    Full Text Available Intracranial aneurysms are fairly common. Many of them produce no symptoms, often remaining undiagnosed during life. At autopsy, aneurysms of the basilar artery appear in 2 to 5% of the cases; among them, saccular and congenital aneurysms are more common than atherosclerotic and fusiform aneurysms. A case of atherosclerotic aneurysm of the basilar artery diagnosed at autopsy in an 88-year-old man is presented. This patient had been admitted with a diagnosis of ischemic stroke, intracranial hypertension and hydrocephalus, which led physicians to consider a posterior fossa tumor. This paper aims at presenting the autopsy findings that showed the presence of an atherosclerotic aneurysm of the basilar artery.

    2006-01-01

    A 27-year-old man was admitted to our hospital for investigation of severe claudication in his right foot. Based on the findings of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), we diagnosed anatomic popliteal artery entrapment syndrome, which was causing a short popliteal artery occlusion. Moreover, a long posterior tibial artery occlusion and a peroneal artery lesion had developed as distal thromboembolic complications of the entrapment. Thus, we planned to perform in situ vein bypass graft for the popliteal occlusion and start thrombolytic treatment for the posterior tibial and peroneal lesions. While contemplating the operation, the patient showed a gradual clinical improvement over the next 2 months. A second MRA showed total arterial recanalization of the right posterior tibial and peroneal arteries, although the popliteal artery was still occluded. Spontaneous lower limb arterial recanalization is a rare phenomenon. To our knowledge, this is the first case of spontaneous arterial recanalization after a distal thromboembolic event caused by popliteal entrapment syndrome.

  3. Dissecting the determinants of depressive disorders outcome: an in depth analysis of two clinical cases

    Full Text Available Abstract Clinicians face everyday the complexity of depression. Available pharmacotherapies and psychotherapies improve patients suffering in a large part of subjects, however up to half of patients do not respond to treatment. Clinicians may forecast to a good extent if a given patient will respond or not, based on a number of data and sensations that emerge from face to face assessment. Conversely, clinical predictors of non response emerging from literature are largely unsatisfactory. Here we try to fill this gap, suggesting a comprehensive assessment of patients that may overcome the limitation of standardized assessments and detecting the factors that plausibly contribute to so marked differences in depressive disorders outcome. For this aim we present and discuss two clinical cases. Mr. A was an industrial manager who came to psychiatric evaluation with a severe depressive episode. His employment was demanding and the depressive episode undermined his capacity to manage it. Based on standardized assessment, Mr. A condition appeared severe and potentially dramatic. Mrs. B was a housewife who came to psychiatric evaluation with a moderate depressive episode. Literature predictors would suggest Mrs. B state as associated with a more favourable outcome. However the clinician impression was not converging with the standardized assessment and in fact the outcome will reverse the prediction based on the initial formal standard evaluation. Although the present report is based on two clinical cases and no generalizability is possible, a more detailed analysis of personality, temperament, defense mechanisms, self esteem, intelligence and social adjustment may allow to formalize the clinical impressions used by clinicians for biologic and pharmacologic studies.

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

    Much of the detailed, incremental knowledge being generated by current scientific research on ocean acidification (OA) does not directly address the needs of decision makers, who are asking broad questions such as: Where will OA harm marine resources next? When will this happen? Who will be affected? And how much will it cost? In this review, we use a series of mainly US-based case studies to explore the needs of local to international-scale groups that are making decisions to address OA concerns. Decisions concerning OA have been made most naturally and easily when information needs were clearly defined and closely aligned with science outputs and initiatives. For decisions requiring more complex information, the process slows dramatically. Decision making about OA is greatly aided (1) when a mixture of specialists participates, including scientists, resource users and managers, and policy and law makers; (2) when goals can be clearly agreed upon at the beginning of the process; (3) when mixed groups of specialists plan and create translational documents explaining the likely outcomes of policy decisions on ecosystems and natural resources; (4) when regional work on OA fits into an existing set of priorities concerning climate or water quality; and (5) when decision making can be reviewed and enhanced.

    2016-04-10

    Idiopathic pulmonary arterial hypertension is characterized by progressive increase in pulmonary arterial pressure and pulmonary vascular resistance which lead to right ventricular failure and death. Pregnancy in patients with idiopathic pulmonary arterial hypertension is contraindicated because of the high maternal and fetal mortality. The authors present a case of successful pregnancy and delivery of a patient with idiopathic pulmonary arterial hypertension in Hungary for the first time. The aim of the report was to demonstrate that management and treatment of idiopathic pulmonary arterial hypertension in a pregnant woman is a complex and multidisciplinary task that should involve obstetrician, cardiologist and anesthesiologist. Those patients who become pregnant and do not wish to terminate the pregnancy must be referred to obstetric centers where a multidiciplinary approach is taken.

    We report a case of aortic dissection masquerading as acute ischemic stroke followed by intravenous thrombolysis. A 59-year-old man presented with dizziness. After examination, the patient had a seizure with bilateral Babinski signs. Soon after identifying multiple acute infarctions in both hemispheres on diffusion-weighted brain magnetic resonance (MR) imaging, tissue plasminogen activator (t-PA) was administered. Both common carotid arteries were invisible on MR angiography, and subsequent chest computed tomography revealed an aortic dissection. The emergency operation was delayed for 13 hours due to t-PA administration. The patient died of massive bleeding. PMID:27734002

    Full Text Available Acute aortic dissection is a life-threatening event in which prompt and correctdiagnosis is associated with better outcomes. In most cases, there is chestor back pain. However, in rare cases, patients have little or no pain andother symptoms are more conspicuous at presentation. The autors reportsthe case of a 47-year-old female patient who sought medical attention forsudden-onset paraplegia. The physical examination was normal except forbilateral lower limb flaccid paralysis, with abolition of deep tendon reflexes andparaesthesia in both feet. Computed tomography showed aortic dissection,with partial thrombosis of the false lumen, starting after the emergence of theleft subclavian artery and extending, toward the bifurcation of the aorta, to theleft iliac artery. After cerebrospinal fluid drainage, the evolution was favorable.

    Directory of Open Access Journals (Sweden)

    Jović Zoran

    2015-01-01

    Full Text Available Introduction. Spontaneous coronary artery dissection (SCAD is a very rare disease with poor prognosis. It mainly affects young women free of risk factors for coronary artery disease (CAD and women during the peripartum period. The prognosis for myocardial infarction caused by SCAD is poor, management is often difficult and guidelines still missing. Case report. We presented a woman with acute myocardial infarction of anterior wall of the left ventricle, caused by spontaneous dissection of medial segment of the left anterior descending coronary artery. We treated the patient with thrombolytic therapy and performed coronary angiography after that. Finally we decided to do nothing more. Two years later we performed coronary angiography again and founded the coronary artery normal. We also analyzed 19 cases publiched from 1996 to 2012 when coronary artery dissection had been treated with thrombolytic agent. Analysis revealed only one case of 19, with complication after treating SCAD with thrombolysis. Conclusion. Sometimes, regarding myocardial infarction in young women with no risk factors for CAD, especially in young women in peripartum, we should think about SCAD. The presented case, like eight others, demonstrates that good clinical outcomes can be achieved with thrombolysis. In spite of all this, we still need more data to verify that thrombolysis does not have to harm the therapy for SCAD. For the time being thrombolytic therapy could be an option.

    Full Text Available BACKGROUND: Endovascular treatment of peripheral arterial occlusive disease has become increasingly frequent in the past few years. Because it is a less invasive procedure, lower morbidity and mortality rates are associated with this form of treatment. OBJECTIVES: To describe the endovascular procedures performed in iliac arteries for the treatment of peripheral arterial occlusive disease. METHODS: This retrospective study assesses 59 cases of iliac artery angioplasty performed according to a specific protocol from January 2004 to February 2010. RESULTS: Mean age of patients was 62 years (minimum: 42, maximum: 89. Thirty seven were male (62.72% and 22 female (37.28%. The main indications for treatment were moderate to severe intermittent claudication in 30 cases (50.84% and rest pain or trophic lesions (critical ischemia in 29 cases (49.15%. Postoperative follow-up included ankle-brachial index measurements and a duplex ultrasound at 30 days, 3 months, 6 months, 12 months, and every 6 months thereafter. Minimum follow-up time was 3 months, and maximum, 72 months (6 years, with primary and secondary patency rates of 91.37 and 94.82%, respectively. CONCLUSIONS: The results of this case series, combined with literature review results, allow to conclude that the endovascular approach is an effective and safe option to treat peripheral arterial occlusive disease in iliac arteries.

  13. Right-sided aortic arch with anomalous origin of the left subclavian artery: Case report

    2011-01-01

    Full Text Available Introduction. A right-sided aortic arch is a rare congenital defect of the aorta with incidence of 0.05% to 0.1% reported in published series. Usually it is associated with congenital heart anomalies and esophageal and tracheal compression symptoms. We present a case of a right-sided aortic arch of anomalous left subclavian artery origin, accidentally revealed during multislice CT (MSCT supraaortic branches angiography. Case Outline. A 53-year-old female patient was examined at the Outpatients’ Unit of the Vascular Surgery University Clinic for vertigo, occasional dizziness and difficulty with swallowing. Physical examination revealed a murmur of the left supraclavicular space, with 15 mmHg lower rate of arterial tension on the left arm. Ultrasound of carotid arteries revealed 60% stenosis of the left subclavian artery and bilateral internal carotid artery elongation. MSCT angiography revealed a right-sided aortic arch with aberrant separation of the left subclavian artery that was narrowed 50%, while internal carotid arteries were marginally elongated. There was no need for surgical treatment or percutaneous interventions, so that conservative treatment was indicated. Conclusion. A right-sided aortic arch is a very rare anomaly of the location and branching of the aorta. Multislice CT angiography is of great importance in the diagnostics of this rare disease.

    Full Text Available Abstract Introduction Spontaneous intrauterine arterial thrombosis and congenital pulmonary hypoplasia are rare conditions and have not been reported to occur together. The literature rather includes two reports of babies with neonatal pulmonary artery occlusion and post-infarction cysts of the lungs. Case presentation We report a case of a live Caucasian male newborn with left lung hypoplasia that occurred in association with left pulmonary artery thrombosis. Despite a critical neonatal course, including extracorporeal membrane oxygenation, this infant is alive and well at 18 months of age without any neurodevelopmental sequelae or reactive airway disease. Conclusion This association suggests the possibility of an intrauterine vascular event between the fifth and eighth weeks of gestation during early pulmonary artery and lung development.

    This article describes a very unusual case of sciatic pain and motor dysfunction resulting from gluteal artery pseudoaneurysm. A 36-year-old woman with primary infertility sustained an iatrogenic injury to her left gluteal artery during transvaginal ultrasound-guided follicle aspiration. Twenty-five days after the procedure she developed severe left sciatic pain and motor dysfunction. Pelvic computed tomography and magnetic resonance imaging revealed a huge pelvic hematoma. Angiography demonstrated a gluteal artery pseudoaneurysm. Because endovascular occlusion of the aneurysm did not relieve the pain, the patient underwent surgery for evacuation of the hematoma and release of the lumbosacral plexus. This eliminated all her sciatic pain and restored her motor dysfunction completely. The English literature details only five other cases of sciatic pain resulting from gluteal artery aneurysm, and these reports are also discussed.

    Full Text Available Objective: To illustrate the utility of CT coronary angiography in the assessment of patients with anomalous coronary arteries. Methods: A 65-year-old woman who presented with a clinical history of unstable angina was investigated with both computerised tomography and invasive coronary angiography. Results: Coronary angiography demonstrated aberrant coronary arteries all arising from separate ostia from the right coronary cusp. Computerised tomography coronary angiography was required to confirm the course of the aberrant coronary arteries in relation to other cardiovascular structures. Conclusions: This case illustrates the important role of computerised tomography coronary angiography and that early use might avoid the need for invasive coronary angiography.

    As intravascular robotics technology continues to evolve, so do the potential applications. The present case describes the use of the Magellan Robotic System within the pulmonary artery. A 61-year-old female was referred for retrieval of a transected port catheter, which had embolized into the pulmonary artery. After a failed attempt using a conventional technique, retrieval was ultimately successful with assistance of the Magellan system. The unique navigational capabilities and stability of the system may make it a valuable tool in pulmonary artery interventions.

    Main pulmonary artery aneurysms are a rare entity with few available published data. As reported in the literature, operative treatment is commonly recommended but the relation between the size of the aneurysm, its localization, and the risk of rupture is not as well defined as for aortic aneurysms. Proximal lesions that involve the main branches of the pulmonary artery are usually apparent on chest radiographs and must be taken into consideration in the differential diagnosis of mediastinal masses. An early diagnosis allows timely surgical treatment. We report an unusual case of a main pulmonary artery aneurysm presenting with persistent non-productive cough and provide a review of the pertinent published data.

    Traumatic pseudoaneurysm of the middle meningeal artery is rare and is associated with high mortality. Skull fracture is usually an associated feature of this entity. An elderly male was brought to our hospital in a stage of coma. The details of ictus were not known. The Glasgow coma scale score was 9/15. Examination revealed a pseudo-aneurysm arising from the posterior branch of the left middle meningeal artery which was excised. The case is presented for its rarity and its characteristic radiology. Traumatic pseudoaneurysm of middle meningeal artery is rare. It is important to recognize this treatable entity.

    Liver infarction is relatively uncommon. It may be secondary to several conditions such as sepsis, shock, sickle-cell anaemia, eclampsia, vasculitis, metastatic disease, bacterial endocarditis, rheumatic heart disease, trauma, portal venous occlusion or compression, oral contraception, anaesthesia, hepatic artery thrombosis, therapeutical or inadvertent hepatic artery ligation, intra-arterial chemotherapy or embolisation. A case of hepatic infraction, unusual for iatrogenic pathogenesis, submassive extension with acute hepatic failure, and CT findings of an internally branching pattern due to intravascular gas was observed.

    Mice are used frequently as experimental models in the study of ischemic spinal cord injury. The aim of the present study was to describe the arterial blood supply to the thoracolumbar spinal cord in the mouse. The study was carried out on 20 adult mice using the corrosion and dissection technique. Dorsal intercostal arteries were found as branches of the thoracic aorta: as 7 pairs in 80% of cases, as 8 pairs in 15% of cases and as 9 pairs in 5% of cases. The paired lumbar arteries arising from the abdominal aorta were present as 5 pairs in all cases. Along the entire thoracic and lumbar spinal regions, we observed left-sided branches entering the ventral spinal artery in 64.2% and right-sided branches in 35.8% of cases. Along the entire thoracic and lumbar spinal regions, the branches entering the dorsal spinal arteries were left-sided in 60.8% of cases and right-sided in 39.2% of cases. We found some variations in the site of origin of the artery of Adamkiewicz and in the number of dorsal spinal arteries. Documenting the anatomical variations in spinal cord blood supply in the laboratory mouse will aid the planning of future experimental studies and in determining the clinical relevance of such studies.

    Tonsillectomy using a KTP laser has been performed increasingly but is not a routinely practised technique in the UK. In the USA, tonsillectomy is often performed as a day case procedure but, here in the UK, it is still standard practice to admit patients for overnight stay. We present the largest prospective double-blind randomized controlled trial to date (151 patients) comparing KTP laser with standard dissection tonsillectomy and assess the suitability of both procedures for day case surgery. We found that there was significantly less peroperative haemorrhage if tonsillectomy was performed using the KTP laser, but it did cause more postoperative pain, more depression in mood and a higher rate of both reactionary and secondary haemorrhage, which was not significant when compared with conventional dissection. There was no difference in operating time, and over 40% of patients in each group needed overnight admission. We conclude that KTP laser tonsillectomy offers no benefit apart from less intraoperative bleeding over standard dissection tonsillectomy. Discharge from hospital after tonsillectomy was found to be unpredictable. Tonsillectomy is therefore an unsuitable procedure for planned surgery through a day unit, but approximately 58% of patients could be discharged on the same day from an extended day surgery unit, and the rest have one night in hospital.

    Full Text Available Pulmonary artery catheter is an invasive monitor usually placed in high-risk cardiac surgical patients to optimize the cardiac functions. We present this case of blood oozing from the oximetry connection port of the pulmonary artery catheter that resulted in the inability to monitor continuous cardiac output requiring replacement of the catheter. The cause of this abnormal bleeding was later confirmed to be due to a manufacturing defect.

    We tried transcatheter arterial embolization for lower gastrointestinal hemorrhage due to radiation colitis. In this case, colostomy and endoscopic therapy were not effective. We succeeded in arresting the hemorrhage without any complications. Transcatheter embolization is a low-invasive and safe method of treatment. For prevention of inflammation and iatrogenic abscess formation, we repeated this therapy and we tried arterial injection of antibiotics and steroid. And so, this therapy is one of the effective methods. (author)

    We report a case of a mycotic pulmonary aneurysm associated with Candida endocarditis in a 53-year-old male with lymphoma. The initial diagnosis was a pulmonary artery aneurysm attributable to vasculitis, such as that associated with Behcet's disease, but a mycotic pulmonary artery aneurysm was later considered as a differential diagnosis. Identification of valve vegetation on the chest CT was helpful in this regard. We review the literature on the disease etiology, radiological findings, and management options.

    If the appropriate catheterization of the affected vein was not possible because of a narrowed or thrombus-filled venous lumen, successful treatment gets into trouble during catheter directed regional thrombolysis for treatment of deep vein thrombosis. In this situation, intra-arterial thrombolysis can be considered as an alternative treatment, but to the best of our knowledge, only two reports have been described. We present here cases of successful intra-arterial thrombolysis in patients with deep vein thrombosis.

    Among coronary artery anomalies, single coronary artery is one of the rarest anomalies. Pulmonary origins of the coronary arteries, coronary artery fistulae, and anomalous aortic origins of the coronary arteries are the most common anomalies requiring surgical intervention. In this case, we describe the performance of bypass grafting after unsuccessful attempts at percutaneous coronary intervention in a 72-year old male patient with single coronary artery arising from the right sinus of Valsalva and with associated diffuse coronary atherosclerosis. Intraoperative angiography was performed to evaluate the revascularization of this anomalous coronary system. The patient remains symptom free 6 months after the operation.

    Physiological outflow boundary conditions are necessary to carry out computational fluid dynamics simulations that reliably represent the blood flow through arteries. When dealing with complex three-dimensional trees of small arteries, and therefore with multiple outlets, the robustness and speed of convergence are also important. This study derives physiological outflow boundary conditions for cases in which the physiological values at those outlets are not known (neither in vivo measurements nor literature-based values are available) and in which the tree exhibits symmetry to some extent. The inputs of the methodology are the three-dimensional domain and the flow rate waveform and the systolic and diastolic pressures at the inlet. The derived physiological outflow boundary conditions, which are a physiological pressure waveform for each outlet, are based on the results of a zero-dimensional model simulation. The methodology assumes symmetrical branching and is able to tackle the flow distribution problem when the domain outlets are at branches with a different number of upstream bifurcations. The methodology is applied to a group of patient-specific arteries in the liver. The methodology is considered to be valid because the pulsatile computational fluid dynamics simulation with the inflow flow rate waveform (input of the methodology) and the derived outflow boundary conditions lead to physiological results, that is, the resulting systolic and diastolic pressures at the inlet match the inputs of the methodology, and the flow split is also physiological.

  10. Traditional electrosurgery and a low thermal injury dissection device yield different outcomes following bilateral skin-sparing mastectomy: a case report

    2011-05-01

    Full Text Available Abstract Introduction Although a skin- and nipple-sparing mastectomy technique offers distinct cosmetic and reconstructive advantages over traditional methods, partial skin flap and nipple necrosis remain a significant source of post-operative morbidity. Prior work has suggested that collateral thermal damage resulting from electrocautery use during skin flap development is a potential source of this complication. This report describes the case of a smoker with recurrent ductal carcinoma in situ (DCIS who experienced significant unilateral skin necrosis following bilateral skin-sparing mastectomy while participating in a clinical trial examining mastectomy outcomes with two different surgical devices. This unexpected complication has implications for the choice of dissection devices in procedures requiring skin flap preservation. Case presentation The patient was a 61-year-old Caucasian woman who was a smoker with recurrent DCIS of her right breast. As part of the clinical trial, each breast was randomized to either the standard of care treatment group (a scalpel and a traditional electrosurgical device or treatment with a novel, low thermal injury dissection device, allowing for a direct, internally controlled comparison of surgical outcomes. Post-operative follow-up at six days was unremarkable for both operative sites. At 16 days post-surgery, the patient presented with a significant wound necrosis in the mastectomy site randomized to the control study group. Following debridement and closure, this site progressively healed over 10 weeks. The contralateral mastectomy, randomized to the alternative device, healed normally. Conclusion We hypothesize that thermal damage to the subcutaneous microvasculature during flap dissection may have contributed to this complication and that the use of a low thermal injury dissection device may be advantageous in select patients undergoing skin- and nipple-sparing mastectomy.

    Intraoperative Type A aortic dissection is a rare pathology with incidence of 0.06-0.32%. It is associated with a high mortality between 30-50%. Some associated risk factors, including hypertension, enlarged aorta, peripheral vascular disease, advanced age, atheroma, and high arterial pressure on cardiopulmonary bypass, have been identified. Modification of these risk factors could reduce the incidence of this event. Prompt diagnosis and management, with the aid of intraoperative trans-esophageal echocardiography and/or epi-aortic ultrasound has been shown to reduce the mortality to 17%. We illustrate the principles of management of this pathology with the case of a 62-year-old female who developed acute Type A aortic dissection while undergoing minimally invasive mitral valve repair.

    2011-09-01

    Acute aortic dissection is a rare disease, but if it occurs rapid diagnosis and therapy are needed. It is usually seen in elderly patients with long-term persistent arterial hypertension. In younger patients, it is mainly caused by congenital connective tissue disorders, such as Marfan syndrome, or by trauma. We present here a 34-year-old male patient with an acute type A aortic dissection. This patient was a professional parachutist and had carried out a large number of parachute jumps during his lifetime. He was admitted to the emergency department with acute chest pain. The symptoms were not related in time to a parachute jump. During a computed tomography scan, an aortic dissection was diagnosed. The patient was immediately referred to the operating room, and the ascending aorta was replaced by a conduit. After a regular postoperative course, the patient was discharged and recovered completely. Although acute aortic dissection is rare in young patients, it has to be considered in cases of acute chest pain. An immediate diagnosis and adequate therapy are essential to offer the patient a good clinical outcome and long-term survival.

    The decrease in the number of cadaveric donors has proved a limiting factor in the number of liver transplants, leading to the death of many patients on the waiting list. The living donor liver transplantation is an option that allows, in selected cases, increase the number of donors. One of the most serious complications in liver transplantation is hepatic artery thrombosis, in the past considered potentially fatal without urgent re-transplantation. A white male patient, 48 years old, diagnosed with hepatocellular carcinoma in chronic liver failure caused by hepatitis B virus, underwent living donor liver transplantation (right lobe). Doppler echocardiography performed in the immediate postoperative period did not identify arterial flow in the right branch, having been confirmed thrombosis of the right hepatic artery in CT angiography. Urgent re-laparotomy was performed, which consisted of thrombectomy and re-anastomosis of the hepatic artery with segmental splenic artery allograft interposition. The patient started anticoagulation and antiplatelet therapy with acetylsalicylic acid. Serial evaluation with Doppler echocardiography showed hepatic artery patency. At present, the patient is asymptomatic. One of the most devastating complications in liver transplantation, and particularly in living liver donor, is thrombosis of the hepatic artery; thus, early diagnosis and treatment is vital. The rapid intervention for revascularization of the graft avoids irreversible ischemia of the bile ducts and hepatic parenchyma, thus avoiding the need for re-transplantation.

    Subintimal angioplasty is a safe, effective, but nondurable procedure in treating long superficial femoral artery occlusions in patients with severe lower limb ischemia. The authors report a case of acute thrombosis that presented 16 weeks after subintimal angioplasty. The ;;Trellis\\'\\' percutaneous thrombolytic infusion system permitted a controlled site-specific infusion of recombinant tissue-type plasminogen activator (rtPA). The unique design of the ;;Trellis\\'\\' allowed complete aspiration of thrombus and avoiding regional and systemic thrombolytic side effects. The ;;Trellis\\'\\' system is effective in percutaneous management of thrombotic lesions; however, intimal dissection may need to be addressed.

    @@ SCLEROSING cholangitis represents progressing jaundice or/and paroxysmal symptom of cholangitis, finally developing to end-stage of liver disease.When compared with primary sclerosing cholangitis (PSC), there are no apparent differences in pathology and clinical manifestation in secondary sclerosing cholangitis (SSC).But unlike PSC, SSC always has underlying causes, the most common being biliary obstruction, surgical trauma and ischemic injury of bile duct during liver transplantation .1,2 Repeated transcatheter arterial chemoembolization (TACE) leading to progressive SSC was rarely reported.Because of its rapid and irreversible progression, once SSC begins, it is difficult to deal with.Therefore, clinicians need to pay more attention to it.

    1992-12-01

    Full Text Available A 70 years-old man was admitted at our hospital because of unstable angina pectoris. He had essential hypertension and right hemiplegia from a ischemic stroke two years before admission. On neurologic examination, it was found mental disorientation, unstable emotionality, right spastic hemiparesis with right Babinski sign, and segmental myoclonus affecting the superior lip and the palate (palatal nystagmus on the right side. On the CT scan, a giant aneurysm of the basilar artery was detected. We conclude that the segmental myoclonus could be explained by ischemic lesions in the Guillain - Mollaret triangle.

    Iatrogenic aortocoronary dissection is a rare but potentially disastrous complication of percutaneous coronary intervention. The left main dissection extending into distal bifurcation involving both the left anterior descending and left circumflex is a complex and vital complication, which is classified as Eshtehardi Type II dissection. We presented a case of iatrogenic left main coronary artery dissection with upcoming closure of both major branches, which was successfully managed by immediate bail-out TAP-stenting. The 77-year-old patient was discharged without any complication, and 1-year follow-up indicated stent patency and favorable clinical result. Immediate bail-out stenting is a feasible and reasonable initial management for this lethal complication.

    2011-04-01

    Full Text Available Abstract Introduction Pulmonary artery aneurysm is an uncommon disorder with severe complications. The diagnosis is often difficult, since the clinical manifestations are non-specific and the treatment is controversial, as the natural history of the disease is not completely understood. Case presentation We describe the cases of two patients with pulmonary artery aneurysms. The first patient was a 68-year-old Caucasian man with an idiopathic low-pressure pulmonary artery aneurysm together with a pulmonary embolism. The patient preferred a conservative approach and was stable at the 10-month follow-up visit after being placed on anti-coagulant treatment. The second patient was a 66-year-old Caucasian woman with a low-pressure pulmonary artery aneurysm also presented together with a pulmonary embolism. The aneurysm was secondary to pulmonary valve stenosis. She received anti-coagulants and, after stabilization, underwent percutaneous balloon valvuloplasty. Conclusion Pulmonary embolism may be the initial presentation of a low-pressure pulmonary artery aneurysm. No underlying cause for pulmonary embolism was found in either of our patients, suggesting a causal association with low-pressure pulmonary artery aneurysm.

    Full Text Available Context Delayed arterial hemorrhage after pancreatoduodenectomy is defined as bleeding 5 or more days postoperatively. Objective We present the management of delayed hemorrhage after PD, due to gastro-duodenal arterial stump aneurysm. Case report A sixty-nineyear- old man suffering from pancreatic head carcinoma underwent pancreatoduodenectomy. On the 12th postoperative day he developed melena. Endoscopic evaluation revealed occult bleeding coming from the afferent limb of the gastro-jejunal anastomosis. The patient was treated conservatively. On the 15th postoperative day the patient presented a new episode of melena and hematemesis. Upper abdominal series control by computer tomography, selective angiography of the celiac trunk and superior mesenteric artery set the diagnosis of a pseudoaneurysm of the gastro-duodenal arterial stump. The patient was managed by trans-catheter arterial embolization and complete hemostasis was achieved. Conclusion Delayed intraluminal hemorrhage after pancreatoduodenectomy may be caused after pseudoaneurysm due to some visceral arterial stem erosion. Initial management, both diagnostic and therapeutic, should be the angiographic control and trans-catheter embolization of the bleeding vessel. In case of hemodynamic instability or when angiographic embolism is unsuccessful reoperation is the proper treatment.

    Full Text Available Abstract Takayasu’s arteritis (TA is a form of chronic vasculitis that typically occurs in young adult Asian females, but it can also present in younger patients not fitting this classic profile. In these cases, the sequelae are generally similar to those found in adults. The disease predominantly affects the aorta and its primary branches. However, the coronary arteries are also affected in up to 20% of cases, which may precipitate myocardial infarction. Imaging of the coronary arteries therefore becomes critically important in the evaluation of a patient with possible Takayasu’s arteritis. We present a case of a pediatric patient with TA who had no symptoms of angina but who was found to have significant coronary artery involvement on diagnostic imaging. This necessitated tailoring of traditional management.

    Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide. The common causes of primary PPH include uterine atony, abnormal placentation, retained placenta, and birth canal injury. The inferior mesenteric artery (IMA) arises from the aorta and is the main artery to supply the descending and sigmoid colon, as well as the rectum. We present a case of immediate, severe uterine bleeding after a normal vaginal delivery; angiography determined that hemorrhage originated from the IMA, and there were no anastomoses between the IMA and other pelvic arteries. The patient was successfully managed by selective embolization of a distal branch of the IMA. Our case report presents a new and interesting variation of pelvic vascular anatomy; moreover, it is the first report to present a case of postpartum uterine bleeding originating from the IMA.

    Full Text Available Iliac vascular injuries have high morbidity and mortality rates. Penetrant abdominal and pelvic vascular injuries are more common compared to blunt traumas. Pelvic vascular injuries associated with blunt trauma are quite likely to occur in accompaniment with pelvic fracture. A 23 year old male patient was admitted to the emergency room due to a motorcycle accident. Shock picture was prevalent in the patient. Shaft fracture was present in left femur and flow was not detected in arterial and venous colour Doppler ultrasonography. Patient underwent emergency surgery. Left main iliac artery and vein were normal, however, external iliac vein was lacerated in two spots, and blood vessel wall integrity was damaged in one part of left external iliac artery. Clinical presentation and traumatic retroperitoneal hematoma management of iliac artery and venous injuries due to blunt trauma without pelvic fracture are discussed in the presented case.

  9. Blunt injury to the inferior gluteal artery: case report of a rare "near miss" event

    Full Text Available Abstract Traumatic injuries of the inferior gluteal artery are rare, the majority of which are aneurysms due to sharp or blunt trauma. We report the rare case of a "near miss" event of a patient with an acute hemorrhagic mass in the right buttock caused by blunt trauma to the inferior gluteal artery without "hard" clinical signs of vascular injury. Despite the unusual presentation, diffuse injury of the inferior gluteal artery branches was diagnosed by ultrasonography and angiography. This article highlights the importance of considering an arterial injury following blunt trauma to the buttock with subsequent pain and swelling. Appreciation of this rare injury pattern is necessary in order to facilitate rapid diagnosis and appropriate treatment.

    Full Text Available Life-threatening hemoptysis is one the most challenging condition encountered in critical care. Bronchial artery embolization (BAE has become an established procedure, in the management of massive and recurrent hemoptysis. Bronchial arteries have variable anatomy. The reported prevalence of bronchial arteries with an anomalous origin ranges from 8.5 -35%. We are describing two patients who presented with hemoptysis and were effectively managed with bronchial artery embolization. Both these patients had anomalous origin of bronchial artery from the internal mammary artery, one from the Right Internal Mammary Artery (RIMA and one from the Left Internal Mammary Artery (LIMA. The procedures were performed under general anesthesia. In the first case a double lumen endobronchial tube was used while in the second case, the patient was managed without tracheal intubation. The first patient was dyspnoeic; saturation was poor and was unable to maintain her airway probably due to profuse blood in her airways. We used a double lumen tube in her to isolate the diseased lung from the healthier lung. We gave her muscle relaxants and mechanical ventilation so that a stable lung field could be provided during embolization. The second patient was quite stable and comfortable while breathing room air. We decided not to interfere with his airway. A back-up plan and preparation for urgent airway control and lung isolation was done inside the catheterization laboratory.From the management point of view, an unstable patient with life-threatening hemorrhage needs airway control and lung isolation. A stable patient with minimum to moderate bleeding may be managed safely under general anesthesia with the patient spontaneously breathing.

    Full Text Available We are reporting a case of familial thoracic aortic aneurysm and dissection in a 26-year-old man with no significant past medical history and a family history of dissecting aortic aneurysm in his mother at the age of 40. The patient presented with cough, shortness of breath, and chest pain. Chest X-ray showed bilateral pulmonary infiltrates. CT scan of the chest showed a dissection of the ascending aorta. The patient underwent aortic dissection repair and three months later he returned to our hospital with new complaints of back pain. CT angiography showed a new aortic dissection extending from the left carotid artery through the bifurcation and into the iliac arteries. The patient underwent replacement of the aortic root, ascending aorta, total aortic arch, and aortic valve. The patient recovered well postoperatively. Genetic studies of the patient and his children revealed no mutations in ACTA2, TGFBR1, TGFBR2, TGFB2, MYH11, MYLK, SMAD3, or FBN1. This case report focuses on a patient with familial TAAD and discusses the associated genetic loci and available screening methods. It is important to recognize potential cases of familial TAAD and understand the available screening methods since early diagnosis allows appropriate management of risk factors and treatment when necessary.

    Full Text Available Abstract Introduction Pulmonary arterial hypertension is a complication of systemic lupus erythematosus. Mortality in pregnant patients with pulmonary arterial hypertension related to connective tissue disease is as high as 56%. The authors report the first case of a successful maternal-fetal outcome in a pregnant patient with systemic lupus erythematosus-associated pulmonary arterial hypertension treated with sildenafil and inhaled iloprost during pregnancy and until several weeks after caesarean section. Case presentation The case presented is of a 29-year-old woman with systemic lupus erythematosus and associated severe pulmonary arterial hypertension. Vasodilator therapy with bosentan and sildenafil, immunosuppressive therapy with prednisone, hydroxychloroquine and azathioprine and oral anticoagulation (phenprocoumon had normalized her right ventricular over right atrial pressure when she was diagnosed in her 5th week of pregnancy. The teratogenic drugs bosentan and phenprocoumon were stopped, the latter replaced by low molecular weight heparin. During the 35th week, a slight increase in pulmonary pressure was found. Therapy with inhaled iloprost was established. A caesarean section was performed in the 37th week and a healthy baby was delivered. The patient remained stable until 11 weeks after delivery, when an increase in right ventricular over right atrial pressure was noted. Bosentan was reintroduced and prednisone and azathioprine doses were increased. The patient has remained stable until the present time. Conclusion Pulmonary arterial hypertension has been considered a contraindication for pregnancy. Novel vasodilator therapy, combined with immunosuppressants in this patient with systemic lupus erythematosus, may "cure" pulmonary arterial hypertension and permit pregnancy with successful outcome. However, postpartum exacerbation of systemic lupus erythematosus and pulmonary arterial hypertension have to be considered.

    Neonatal arterial thrombosis is a very rare entity with clinical findings resembling coarctation of aorta or interrupted aortic arch. A two day-old male newborn was admitted to a different hospital with difficulty in sucking and sleepiness. On echocardiographic examination, a diagnosis of interrupted aortic arch was made and he was treated with prostoglandin E2. When the patient presented to our center, physical examination revealed that his feet were bilaterally cold. The pulses were not palpable and there were ecchymotic regions in the lower extremities. Echocardiography ruled out interrupted aortic arch. Computerized tomographic angiography revealed a large thrombosis and total occlusion of the abdominal aorta. Since there was no response to treatment with tissue plasminogen activator, we performed thrombectomy. Homozygous Factor V Leiden and Methylenetetrahydrofolate reductase mutations were found in this patient. Neonatal aortic thrombosis which is observed very rarely and fatal should be considered in the differential diagnosis of coarctation of aorta and interrupted aortic arch.

    Full Text Available Arterial conduits are necessary in nearly 5% of all liver transplants and are usually constructed utilizing segments of donor iliac artery. However, available segments of donor iliac artery may not be lengthy enough or may not possess enough quality to enable its inclusion in the conduit. Although there are few reports of arterial conduits constructed solely utilizing prosthetic material, no previous reports of conduits composed of a segment of donor iliac artery and prosthetic material (mixed biologic and synthetic arterial conduits were found in the medial literature to date. Two cases reporting successful outcomes after creation of mixed biologic and prosthetic arterial conduits are outlined in this report. Reason for creation of conduits was complete intimal dissection of the recipient’s hepatic artery in both cases. In both cases, available segments of donor iliac artery were not lengthy enough to bridge infrarenal aorta to porta hepatis. Both patients have patent conduits and normally functioning liver allografts, respectively, at 4 and 31 months after transplant. Mixed biologic and synthetic arterial conduits constitute a viable technical option and may offer potential advantages over fully prosthetic arterial conduits.

  19. Dextran Microsphere Hepatic Artery Embolization for Hepatoma: Pathological Assessment of Its Efficacy in Resected Cases

    2001-01-01

    Objective To evaluate the therapeutic effect and the mechanism of dextran microsphere hepatic artery embolization for hepatoma. Methods Partial hepatectomy was performed in 11 patients with hepatoma pretreated with dextran microsphere hepatic artery embolization. All specimens were for histopathologic studies in order to observe the destiny of dextran microspheres and necrotic degree of the tumor. Results complete necrosis of the tumor was found in seven cases and incomplete necrosis of the tumor in the rest 4. Tumors in the later were near to areas rich in arterial collateral anastomoses. The extent of tumor necrosis was unrelated to the presence and thickness of tumor capsule and capsular invasions. Dextran microspheres could cause permanent embolization of distal arterioles. The microspheres were very biocompatible and cause little foreign body reaction. No inflammatory changes were seen both inside and outside of the embolized artery 191 days after embolization. Dextran microspheres were not absorbed and the vessel recanalization was also not seen. Dextran microsphere was not found in portal veins. Conclusion Some hepatomas distant from the collateral circulation of arteries could be cured with dextran microsphere hepatic artery embolization alone.

    Pediatric polyarteritis nodosa is rare systemic necrotizing arteritis involving small- and medium-sized muscular arteries characterized by aneurysmal dilatations involving the vessel wall. Aneurysms associated with polyarteritis nodosa are common in visceral arteries; however intracranial aneurysms have also been reported and can be associated with central nervous system symptoms, significant morbidity, and mortality. To our knowledge extracranial involvement of the vertebral arteries has not been reported but has the potential to be deleterious due to fact that they supply the central nervous system vasculature. We present a case of a 3-year-old Haitian boy with polyarteritis nodosa that presented with extracranial vessel involvement of his vertebral arteries. After thorough diagnostic imaging, including a bone scan, ultrasound, Magnetic Resonance Imaging/Angiography, and Computed Tomography Angiography, he was noted to have vertebral artery vasculitis, periostitis, subacute epididymoorchitis, arthritis, and myositis. He met diagnostic criteria for polyarteritis nodosa and was treated with cyclophosphamide, methylprednisolone, and tocilizumab, which resulted in improvement of his inflammatory markers, radiographic findings, and physical symptoms after treatment. To the authors' knowledge, this is the first report of vertebral artery vasculitis in polyarteritis nodosa as well as successful treatment of the condition using the combination cyclophosphamide and tocilizumab for this condition.

    Full Text Available Abstract Acute aortic type A dissection is a life-threatening disease that requires immediate surgical intervention. When dissection occurs during pregnancy, it is of high risk for both the mother and the fetus. In this study, we reported two cases of acute aortic dissection in late pregnancy at 28 weeks and 32 weeks of gestation respectively. After the two patients underwent a cesarean section and delivered a baby, we performed composite graft replacement of the aortic valve, aortic root and ascending aorta, with re-implantation of the coronary arteries into the graft (Bentall procedure instead of repairing the arch with deep hypothermia and circulation arrest. Both mothers and children survived and recovered well.

    Abstract The present study was aimed to investigate the application of right thansthoracic Ivor–Lewis (IL), left transthoracic (LTT), and left thoracoabdominal (LTA) approach in Siewert type II adenocarcinoma of esophagogastric junction (AEG). The data of 196 patients with Siewert type II AEG received surgical resection in our cancer center between January 2014 and April 2016 was retrospectively analyzed. Finally, 136 patients met the inclusion criteria were enrolled in the study and divided into the IL (47 cases), LTT (51 cases), and LTA group (38 cases). Clinical and short-term treatment effects were compared among the 3 groups. The patients with weight loss, diabetes, and heart disease increased in the LTT group (P = 0.054, P = 0.075, and P = 0.063, respectively). Operation time was significantly longest in the IL group (P  0.05), but the dissection rate of the hepatic artery, splenic artery, and celiac trunk lymph nodes was significantly highest in the IL group (P  0.05). Compared with the traditional left transthoracic approach, the Ivor–Lewis approach did not increase the perioperative mortality and complication rates in Siewert type II AEG, but obtained satisfactory length of the proximal surgical margin, and was better than the left transthoracic approach in thoracic and abdominal lymph node dissection. However, the advantages of Ivor–Lewis procedure requires further follow-up and validation through prospective randomized controlled trials. PMID:28207537

    Rationale Thoracic aortic aneurysms leading to acute aortic dissections (TAAD) can be inherited in families in an autosomal dominant manner. As part of the spectrum of clinical heterogeneity of familial TAAD, we recently described families with multiple members that had TAAD and intracranial aneurysms or TAAD and intracranial and abdominal aortic aneurysms inherited in an autosomal dominant manner. Objective To identify the causative mutation in a large family with autosomal dominant inheritance of TAAD with intracranial and abdominal aortic aneurysms by performing exome sequencing of two distantly related individuals with TAAD and identifying shared rare variants. Methods and Results A novel frame shift mutation, p. N218fs (c.652delA), was identified in the SMAD3 gene and segregated with the vascular diseases in this family with a LOD score of 2.52. Sequencing of 181 probands with familial TAAD identified three additional SMAD3 mutations in 4 families, p.R279K (c.836G>A), p.E239K (c.715G>A), and p.A112V (c.235C>T) resulting in a combined LOD score of 5.21. These four mutations were notably absent in 2300 control exomes. SMAD3 mutations were recently described in patients with Aneurysms Osteoarthritis Syndrome and some of the features of this syndrome were identified in individuals in our cohort, but these features were notably absent in many SMAD3 mutation carriers. Conclusions SMAD3 mutations are responsible for 2% of familial TAAD. Mutations are found in families with TAAD alone, along with families with TAAD, intracranial aneurysms, aortic and bilateral iliac aneurysms segregating in an autosomal dominant manner.

  5. Ischemic Stroke of the Artery of Percheron with Normal Initial MRI: A Case Report

    Directory of Open Access Journals (Sweden)

    Guillaume Cassourret

    2010-01-01

    Full Text Available The artery of Percheron is a solitary trunk representing an uncommon anatomic variant that provides bilateral arterial supply to the paramedian thalami and the rostral midbrain. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. The clinical diagnosis is difficult because the complex anatomy causes large clinical variability. We report a case of a comatose patient with normal early head-computed tomography and magnetic resonance imaging. A bilateral paramedian thalamic infarct due to an occlusion of the artery of Percheron was revealed two days later by a new head computed tomography. To our knowledge, this is the first report in the literature of a symptomatic patient presenting an acute Percheron stroke with normal early brain magnetic resonance imaging. Our case indicates that a normal initial magnetic resonance imaging cannot formally eliminate the diagnosis of acute stroke of the artery of Percheron. We discuss the causes of noncontributive brain magnetic resonance imaging at the onset of this acute Percheron stroke and the alternative diagnosis and therapy methods.

    Directory of Open Access Journals (Sweden)

    Baumann Gert

    2005-09-01

    Full Text Available Abstract background Interferon alpha2 is widely used in hepatitis and high-risk melanoma. Interferon-induced pulmonary arterial hypertension as a side effect is rare. Case presentation We describe a melanoma patient who developed severe pulmonary arterial hypertension 30 months after initiation of adjuvant interferon alpha2b therapy. Discontinuation of interferon did not improve pulmonary arterial hypertension. This patient could be treated successfully with phosphodiesterase-5 inhibitor therapy. Conclusion This is only the 5th case of interferon-induced pulmonary arterial hypertension and the first documented case where pulmonary arterial hypertension was not reversible after termination of interferon alpha2 therapy. If interferon alpha2 treated patients develop respiratory symptoms, pulmonary arterial hypertension should be considered in the differential diagnosis. For these patients phosphodiesterase-5 inhibitors, e.g. sildenafil or vardenafil, could be an effective therapeutic approach.

    Full Text Available ABSTRACT: The surgical procedures like appendicectomy, demands a precise knowledge of vascular anatomy of ileocolic region. The aim of th is study is to study the arterial supply of the appendix, findings of which may reveal more anatomica l facts about the arteries of appendix and their variations. Total 52 specimens of caecum a nd appendix with their arteries intact were collected, cleaned and dissected. The ileocolic art ery and its branches to the appendix were traced carefully and observations were recorded.

    Full Text Available During an ordinary dissection, a cadaver showed a bilateral anomalous origin of the deep brachial artery, where this vessel appeared like a branching of the subscapular artery with common trunk, which included the posterior circumflex humeral artery. The course and distribution of the deep brachial artery in the back compartment were relatively consistent with previous reports. Arterial variations can be damaged through iatrogenic means if not properly documented. The knowledge of this case is very important in clinical medicine and in surgeries in this compartment to prevent any injury.Durante dissecação em prática usual, um cadáver apresentou origem anômala da artéria braquial profunda, na qual este vaso apareceu como um ramo da artéria subescapular com um tronco comum, que incluiu a artéria circunflexa posterior do úmero. O curso e a distribuição da artéria braquial profunda no compartimento posterior foram relativamente coincidentes com relatos prévios. Variações arteriais podem ser danificadas de maneira iatrogênica se não forem adequadamente documentadas. O conhecimento desse caso é muito importante na prática clínica e em cirurgias nesse compartimento para prevenção de qualquer injúria.

  16. Successful Treatment of Two Cases of Squamous Cell Carcinoma on the Ear with Intra-Arterial Administration of Peplomycin through a Superficial Temporal Artery

    Full Text Available Cutaneous squamous cell carcinoma (SCC is the second most common non-melanoma skin cancer and tends to develop in sun-exposed cosmetic areas, including the ear. In this report, we describe two cases of SCC on the ear successfully treated with intra-arterial administration of peplomycin through a superficial temporal artery. In addition to this selective chemotherapy, we administered oral tegafur, which achieved complete remission of the tumor. These findings suggest that intra-arterial administration of peplomycin with tegafur is one of the optimal therapies for the treatment of SCC developing on the ear.

    Eagle syndrome (symptoms associated with an elongated styloid process (SP)) is commonly divided into two presentations. First, the so-called classic Eagle syndrome where patients can present with unilateral sore throat, dysphagia, tinnitus, unilateral facial and neck pain and otalgia. Second, there is the vascular or stylocarotid form of Eagle syndrome in which the elongated SP is in contact with the extracranial internal carotid artery. We describe two cases of internal carotid artery dissection associated with an elongated SP. One is a patient with ischaemic stroke and another with transient ischaemic attacks caused by an elongated SP. A surgical resection of the SP was performed on the former patient. Both patients were treated with anticoagulation and recovered well. A literature search only revealed two prior descriptions of carotid dissection in the context of an elongated SP.

    Aim: To report two cases of the left testicular artery arching over the left renal vein (LRV) before running downward to the testis. Methods: The subjects were obtained from two Japanese cadavers. During the student course of gross-anatomical dissection, the anatomical relationship between the testicular vessels and the renal vein was specifically observed. Results: The arching left testicular artery arose from the aorta below the LRV and made a loop around the LRV, which appeared to be mildly compressed between the arching artery and the psoas major muscle.Conclusion: Clinically, compression of the LRV between the abdominal aorta and the superior mesenteric artery occasionally induces LRV hypertension, resulting in varicocele, orthostatic protenuria and hematuria. Considering that the incidence of a left arching testicular artery is higher than that of a right one, an arching left artery could be an additional cause of LRV hypertension.

    A 55-year-old man with esophageal carcinoma received endoscopic submucosal dissection (ESD) in en-bloc resection. Histopathological examination revealed an admixture of squamous cell carcinoma (SCC) and endocrine cell carcinoma (ECC) with invasion of the deep submucosa. Immunohistochemically, CD 56 and chromogranin A were positive for ECC. Small-cell, medium-cell, and large-cell type ECC were partly surrounded with SCC and partly formed the duct, presenting various patterns. After ESD, he received chemotherapy including CPT-11 plus Cisplatin. He is alive and in good condition today, 55 months after ESD, with no evidence of recurrence.

    2016-01-01

    An association between closed posterior elbow dislocation and traumatic brachial artery injury is rare. Absence of radial pulse on palpation is an important warning sign and arteriography is the gold-standard diagnostic test. Early diagnosis is essential for appropriate treatment to be provided. This consists of joint reduction and immobilization, along with urgent surgical restoration of arterial flow. Here, a case (novel to the Brazilian literature) of an association between these injuries (and the treatment implemented) in a 27-year-old male patient is reported. These injuries were sustained through physical assault. PMID:27069896

  1. Aberrant right subclavian artery- suggested mechanism for esophageal foreign body impaction: Case report

    2011-04-01

    Full Text Available Abstract Aberrant right subclavian artery (ARSA is asymptomatic in most cases. This variant anatomy can cause dysphagia in elderly patients. Impaction of foreign body in the esophagus is rarely the presenting symptom of ARSA. We present an eighty four years old patient who first presented with esophageal foreign body impaction and was diagnosed with an aberrant right subclavian artery compressing the esophagus just below the site of impaction. We assume that the exact place of impaction was not incidental and that a relative narrowing of the esophagus caused by the vascular anomaly is responsible for this specific presentation.

    2006-01-01

    Percutaneous liver biopsy is considered one of the most important diagnostic tools to evaluate diffuse liver diseases. Pseudoaneurysm of hepatic artery is an unusual complication after ultrasound-guided percutaneous liver biopsy. Delayed hemorrhage occurs much less frequently. We report a case of pseudoaneurysm of the hepatic artery of a 46-year-old man who was admitted for abdominal pain after 4 d of liver biopsy. The bleeding was controlled initially by angiographic embolization.However, recurrent bleeding could not be controlled by repeat angiography, and the patient died 4 d after admission from multiorgan failure. The admittedly rare possibility of delayed hemorrhage should be considered whenever a liver biopsy is performed.

    We present the case of a 65-year-old gentleman, who presented with a symptomatic pseudoaneurysm of the right common carotid artery. Because of high surgical risk, endovascular approach was decided upon. However, taking hardware across the lesion via the aortic arch provided us with insurmountable difficulties. Therefore, a hybrid approach was resorted to, in which an arteriotomy was done in the carotid artery followed by direct implantation of the stent. We were thus able to create a favorable trade-off between the high surgical risk of a full surgical procedure and the peri-operative benefit of an endovascular approach.

    An unusual case resulted from a motor vehicle accident presented with hemo-mediastinum and left pneumohemo~throrax and delayed anterior myocardial infarction. Further examination revealed a traumatic transection of left anterior descending coronary artery and a thoracic ortic rupture. Percutaneous revascularization of the left anterior descending artery was unsuccessful because the gidewire failed to pass through the stenosis, but aortic disruption was successfully stented with a stent graft. The patient recovered well, but aneurysm of cardiac anterior wall and decreased heart function remained.

    Full Text Available Uterine artery embolization is a highly specialised and efficacious method that can be used prophylactically to reduce obstetric haemorrhage. Its use in modern obstetrics is currently limited to morbidly adherent placenta and acreta. This report presents a case where uterine artery embolization has been used as the primary treatment for obstetric haemorrhage in a patient with high risk for PPH where surgical management would not have been possible. We aim at highlighting the benefits of this procedure in terms of reduced surgical blood loss, morbidity and fertility preservation. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 2093-2095

    Full Text Available Abstract Although about 30% of gastric cancers have distant metastasis at the time of initial diagnosis, metastatic tumor embolus in the main blood vessels is not common, especially in the main artery. The report presents, for the first time, an extremely rare clinical case of a metastatic embolus in the common carotid artery (CCA from primary gastric cancer. Metastatic embolus from the primary tumor should be considered when patients present with gastric cancer accompanied by intravascular emboli. The patient should be actively examined further so as to allow early detection and treatment.

    We report a case of multiple abnormalities with eustachian tube obstruction by a protruded internal carotid artery. A 10-year-old male presented with multiple abnormalities including anomalous pinna, poor eyesight, facial palsy, moderate conductive deafness, and otitis media with effusion. Temporal bone computed tomography demonstrated obstruction of the right eustachian tube by a protruded internal carotid artery. Insertion of a tympanostomy tube did not improve his hearing, indicating a possible ossicular chain anomaly. Although tympanoplasty is necessary to improve the patients' hearing, the poor drainage function makes this difficult. Knowledge of this vascular anomaly is important when performing myringotomy or tympanoplasty.

    Anomalous origin of coronary arteries is a relatively rare entity and can present different clinical forms. Recently, CT angiography of the coronary arteries have demonstrated an important role in the diagnosis and management of these anomalies. We present the case of a young female without significant comorbidities who presented with cardiopulmonary arrest, being revived by a team of customer service mobile emergency. After completion of multislice CT angiography of the coronary arteries was observed anomalous origin of left main coronary artery in the right coronary artery, no signs of extrinsic compression. Patient received a defibrillator and had an uneventful follow-up performed. Multislice CT angiography is minimally invasive diagnostic methods to detect the origin and trajectory of the coronary arteries, allowing an alternative to cardiac catheterization for evaluation of patients with anomalous origin of coronary arteries.

    Pulmonary arteriovenous fistulas (PAVFs) are rare. Diffuse type PAVFs with pulmonary arterial hypertension (PAH) are even rarer and can elude anatomy imaging like a plain chest film or a computed tomography. The rapid blood flow that ensues due to lack of a capillary bed leads to various degrees of ischemia depending on the number and size of the PAVF. This is a case report of diffuse PAVF in a patient with PAH.This case report describes a patient with recurrent hemoptysis and chest pain. Systemic examination was unremarkable except for P2 attenuation on auscultation. Echocardiograghy showed confirmed pulmonary hypertension with mild dilation of right atrium and ventricle and a tricuspid regurgitation pressure gradient of 40 mm Hg and ruled out congenital heart diseases. Right heart catheterization revealed precapillary PAH with mean pulmonary arterial pressure of 88 mm Hg. Pulmonary angiography showed enlarged pulmonary arterial trunk and diffuse spiral tortuous pulmonary arterial branches indicting diffuse PAVFs. The patient was diagnosed as PAH and began treatment of 25 mg tid of sildenafil.The case highlights a rare and unique presentation of PAH.

    Thirty children, 17 boys and 13 girls, with 31 arterial traumatisms, were studied. The follow-up period ranged from 4 to 166 months. The purpose of this study was to analyze the long term results. The etiology in 19 cases was accidental (61.3%) and iatrogenic in 12 (38.7%). Upper limbs were affected in 15 cases, lower limbs in 13. The arterial traumatism affected the supra-aortic truncus in 2 patients and the renal artery in one other. Arteriographies were carried out in 7 cases (22.6%). Twenty-three patients (74.2%) underwent surgical procedures. The rest of the patients were managed conservatively. No amputations were needed. Three patients died by no vascular causes. The long-term results were good in terms of permeability and absence of major sequels. We conclude that IAT (Infantile Arterial Traumatisms) are potentially graves; therefore an early diagnosis and a specialized care of patients, without rigid protocols of management, are needed. The uncertain prognosis of IAT obligate to a clinical follow-up.

  13. Pregnancy after Uterine Artery Embolization: A Case Report in a Woman with Leiomyomata

    Directory of Open Access Journals (Sweden)

    Helena Isabel Lopes

    2015-01-01

    Full Text Available Background. Several pregnancies have been reported after embolization of uterine artery. This procedure is an accepted nonsurgical treatment for symptomatic uterine fibroids but its safety in women desiring future childbearing is not well established. Case Report. We present a 40-year-old woman with leiomyomata who became pregnant after previously undergone uterine artery embolization for three times. The placenta was previa and the fetus was in transverse position. She had a cesarean delivery of an appropriately grown fetus at 37 weeks, which was followed by uterine atony requiring hysterectomy. Conclusion. Although pregnancy-related outcomes remain understudied, the available reports evidence that pregnancies after uterine artery embolization may be at significantly increased risk for postpartum hemorrhage, cesarean delivery, abnormal placentation, and malpresentation. In patients who are undergoing this type of treatment and contemplating pregnancy, the possibility of adverse complications should be taken in consideration and women should be appropriately advised.

    PHACE and PHACES are acronyms for a syndrome of variable expression comprising posterior cranial fossa malformations, facial haemangiomas, arterial anomalies, aortic coarctation and other cardiac disorders, ocular abnormalities and stenotic arterial disease. We review five girls and three boys aged 1 month-14 years with disorders from this spectrum. Six had large facial haemangiomas but recent reports suggest that small haemangiomas may occur; hence our inclusion of two possible cases. We also focus on the recently recognised feature of progressive intracranial arterial occlusions, present in four of our patients, later than previously recognised, from 4 to 14 years of age. We suggest that many elements of this disorder could reflect an abnormality of cell proliferation and apoptosis. (orig.)

Methods To retrospectively analyze the clinical features and the characteristics of coronary angiography and the optical co-herencje tomography image of a case who admitted with acute anteroseptal myocardial infarction and review relative literatures. Results Coronary angiography shows 70% portion of narrowness at the second segment of LAD, OCT imaging detected "dissection-like" image at the site of where coronary angiography shows '"normal". Actually, we consider the "dissection" as the fiber remnant of thrbmbolysis by carefully identification. Conclusion Coronary angiography shows "normal" doesn' t mean really normal, some patient with coronary artery disease may be missed diagnosis. The fiber remnant of thrombosis found may affect thr prognosis of patient with ACS. The finding of the case provides evidence for prolongation of dual anti-platelet therapy for patients with ACS not treated

    The advent of flow dynamics and the recent availability of perfusion analysis software have provided new diagnostic tools and management possibilities for cerebrovascular patients. To this end, we provide an example of the use of color-coded angiography and its application in a rare case of a patient with a pure middle cerebral artery (MCA) malformation. A 42-year-old male chronic smoker was evaluated in the emergency room due to sudden onset of severe headache, nausea, vomiting and left-sided weakness. Head computed tomography revealed a right basal ganglia hemorrhage. Cerebral digital subtraction angiography (DSA) showed a right middle cerebral artery malformation consisting of convoluted and ectatic collateral vessels supplying the distal middle cerebral artery territory-M1 proximally occluded. An associated medial lenticulostriate artery aneurysm was found. Brain single-photon emission computed tomography with and without acetazolamide failed to show problems in vascular reserve that would indicate the need for flow augmentation. Twelve months after discharge, the patient recovered from the left-sided weakness and did not present any similar events. A follow-up DSA and perfusion study using color-coded perfusion analysis showed perforator aneurysm resolution and adequate, albeit delayed perfusion in the involved vascular territory. We propose a combined congenital and acquired mechanism involving M1 occlusion with secondary dysplastic changes in collateral supply to the distal MCA territory. Angiographic and cerebral perfusion work-up was used to exclude the need for flow augmentation. Nevertheless, the natural course of this lesion remains unclear and long-term follow-up is warranted.

    Aim: To highlight the variation in clinical manifestations, imaging and management of four cases of unilateral pulmonary artery agenesis presenting in adulthood. Method: Four patients with unilateral pulmonary artery agenesis were referred to our institution between 1995 and 2005. They underwent a series of investigations, including chest radiography, echocardiography, ventilation perfusion scintigraphy, angiography, computed tomography (CT) and magnetic resonance imaging (MRI). Results: Two of the four patients had absence of the right main pulmonary artery, whilst the remaining two patients had absence of the left main pulmonary artery. One patient showed a restrictive defect on pulmonary function tests. Two patients who had ventilation perfusion scintigraphy showed absent perfusion and reduced ventilation on the affected side. Angiography (where performed), CT and MRI confirmed the anatomy and the presence of multiple collaterals. Bronchiectasis was demonstrated on CT in two patients, with one also demonstrating a mosaic attenuation pattern. One patient had an incidental lung tumour on the side of the agenesis, which was diagnosed as a chondroid hamartoma on histology. Three of the four patients eventually underwent resection of the affected lung. Conclusion: Isolated unilateral pulmonary artery agenesis has a non-specific presentation. Awareness of this condition can lead to earlier diagnosis, with cross-sectional imaging making an important contribution.

    2005-06-01

    Full Text Available High flow priapism is a rare entity caused by a pathologic influx from lacerated arteries to the cavernous bodies. Transcatheter embolization of feeding arteries is the treatment of choice. We reviewed a series of 5 patients who un derwent transcatheter embolization in our hospital from 2000 to 2004. The mean age of patients was 32 years; dur ation of priapism was between one week and a year. All underwent bilateral pudendal artery ca theterization with No.5 French Cobra-II catheters. We did not microcatheters in our patien ts. Embolized materials were gel-foam, coils and polyvinyl alcohol microspheres. We could follow four of them for 6 to 40 months; one of the patients dropped out from our follow-up study. All the four patients had completed detumescence after a maximum of two days from embolization;none of them experienced signific ant complications and all returned to normal sexual function and remained symptom free thereafter (6-40 months. We noted no difference in complications and duration to restore erectile function and less recurrence rate with embolization of main br anch of pudendal artery instead of superselective embolization of arteriocavernous fistul a feeder artery with a microcatheter that is the method of choice for the treatment of high flow priapism, but due to small number of cases it needs further studies to be confirmed.

    A 87-year-old man received radical nephroureterectomy for right renal pelvic cancer in 2009 and left cutaneous ureterostomy after radical cystectomy for bladder cancer in 2013. He visited the hospital for exchanging a 7 or 8 Fr single-J catheter every 2 to 4 weeks. Eleven months after the 2nd operation, massive bleeding from the stoma occurred when ureteral catheter was exchanged. Contrast-enhanced computed tomography showed that left inferior epigastric artery was located close to left ureter. Angiography of the left inferior epigastric artery didn't show an obvious fistula, but revealed the stoma was surrounded by ramified new blood vessels from left inferior epigastric artery. We suspected a rupture of the vessels and performed embolization for the branch of inferior epigastric artery to left ureter. This embolization made it possible for the bleeding to be controlled. Massive bleeding from the branch of inferior epigastric artery is very rare, and we report the case and review the literature.

    Purpose: To evaluate the feasibility and effectiveness of IVUS-guided puncture for gaining controlled target lumen reentry in subintimal recanalization of chronic iliac/femoral artery occlusions and in fenestration of aortic dissections. Materials and Methods: Between 5/2004 and 12/2005 12 consecutive patients (7 male, 5 female; mean age 64.6{+-}12.0 years) with chronic critical limb ischemia and ischemic complications of aortic dissection were treated using the Pioneer trademark catheter. This 6.2-F dual-lumen catheter combines a 20-MHz IVUS transducer with a pre-shaped extendable, hollow 24-gauge nitinol needle. This coaxial needle allows real-time IVUS-guided puncture of the target lumen and after successful reentry a 0.014'' guidewire may be advanced through the needle into the target lumen. 7 patients were treated for aortic dissection and 5 patients (with failed previous attempts at subintimal recanalization) for chronic arterial occlusion. Patients with aortic dissection (5 type A dissections, 2 type B dissections) had developed renal ischemia (n=2), renal and mesenteric ischemia (n=2), or low extremity ischemia (n=3). Patients with chronic arterial occlusions (2 common iliac artery occlusions, 3 superficial femoral artery occlusions) experienced ischemic rest pain (n=4), and a non-healing foot ulcer (n=1). Results: The technical success rate using the Pioneer catheter was 100%. The recanalization/fenestration time was 37{+-}12 min. Procedure-related complications did not occur. In 10 cases a significant improvement of clinical symptoms was evident. One patient with aortic dissection and ischemic paraplegia required subsequent surgical intervention. One patient had persistent ischemic rest pain despite successful recanalization of a superficial femoral artery occlusion. (orig.)

    More than one quarter of all transient ischemic attacks (TIA's) and ischemic strokes involve tissue supplied by the vertebrobasilar (VB) circulation. Vertebral artery stenotic lesion, particularly at the origin of the vertebral artery, is not uncommon but it is a less studied area. Here we present our endovascular treatment experience in a group of patients with vertebral artery orifice stenosis. We enrolled a group of patients with vertebral artery orifice stenosis who presented with confirmed posterior circulation stroke. Vertebrobasilar insufficiency syndrome was confirmed by imaging studies and clinical findings. Vertebral artery stenosis diagnosed by CT or MR Angiography and confirmed by Conventional and digital subtraction angiography (DSA). Angiography was performed by using of femoral or radial artery approach. From October 2008 to January 2010, forty-three consecutive patients (69.8% men) underwent stent placement for symptomatic vertebral artery orifice stenosis. Mean degree of stenosis was 70.45 +/- 7.455 percent and mean age was 71.65 +/- 7.743 years . In the 22 patients (22/43, 51.16%) stenosis were in left side. In the thirty patients (30/43, 69.6%) there was evidence of atherosclerotic disease in the internal carotid artery and in the 23% contra lateral vertebral artery was involved. There were five different cases with left renal artery stenosis especially in the men with left vertebral artery stenosis. Initial technical success rate was 100%. No cerebrovascular complications or embolic events occurred. Six months control angiography follow-up revealed one patient with stent occlusion and moderate (40%) restenosis in the another patient. According to our finding angioplasty and stenting for vertebral artery orifice stenosis is safe and effective. Patients with vertebral artery orifice disease frequently have coexistent atherosclerotic stenosis in the other major extracranial arteries including carotid and renal arteries.

    Full Text Available Abstract Background Upper gastrointestinal haemorrhage is mainly caused by ulcers. Gastric varicosis due to portal hypertension can also be held responsible for upper gastrointestinal bleeding. Portal hypertension causes the development of a collateral circulation from the portal to the caval venous system resulting in development of oesophageal and gastric fundus varices. Those may also be held responsible for upper gastrointestinal haemorrhage. Case presentation In this study, we describe the case of a 69-year-old male with recurrent severe upper gastrointestinal bleeding caused by arterial submucosal collaterals due to idiopathic splenic artery thrombosis. The diagnosis was secured using endoscopic duplex ultrasound and angiography. The patient was successfully treated with a laparoscopic splenectomy and complete dissection of the short gastric arteries, resulting in the collapse of the submucosal arteries in the gastric wall. Follow-up gastroscopy was performed on the 12th postoperative week and showed no signs of bleeding and a significant reduction in the arterial blood flow within the gastric wall. Subsequent follow-up after 6 months also showed no further gastrointestinal bleeding as well as subjective good quality of life for the patient. Conclusion Submucosal arterial collaterals must be excluded by endosonography via endoscopy in case of recurrent upper gastrointestinal bleeding. Laparoscopic splenectomy provides adequate treatment in preventing any recurrent bleeding, if gastric arterial collaterals are caused by splenic artery thrombosis.

    Full Text Available Background: The profunda femoris artery is the major branch of the femoral artery. It is at critical place in relation to femoral artery for various interventions. Aim: To study the origin of profunda femoris artery. And to compare the cross sectional area of profunda femoris artery between right and left limbs. Material and methods: In this cross sectional study, 51 human femoral triangles from 26 (18 male and 08 female human cadavers in P.D.U. Government Medical College, Rajkot were dissected and studied during regular dissection classes. Site of origin of profunda femoris artery was noted in relation to femoral artery. The distance of origin of profunda femoris artery from the midpoint of inguinal point was measured and noted. Circumference of profunda femoris artery at the level of origin was measured. The cross sectional area was calculated. Collected data was analyzed by standard statistical formulas with the help of Microsoft excel 2007 and Epi info TM 7 software. Result: Most common (52.95% cases site of origin was posterolateral from femoral artery. The mean distance of origin of profunda femoris artery from the midpoint of inguinal ligament was 30.17 mm. There was no significant difference in cross sectional area of right and left profunda femoris artery (at 95% confidence interval Conclusion: Profunda femoris artery is used for angiography, ultrasonography and cardiac catheterization also. It is the major blood supply of the thigh. Its relations with femoral artery, femoral vein and femoral nerve makes it important structure for clinicians. Variations in origin of profunda femoris artery must be considered to avoid complication like aneurism and faulty passage of the catheter. High origin of profunda femoris artery is more prone to damage while accessing femoral artery.

    Neurofibromatosis type I (NF-1) is the most common neurocutaneous syndrome. Associated vascular abnormalities are arterial occlusion, aneurysm, ectasia and arteriovenous malformation. Spontaneous massive hemothorax due to rupture of an arterial aneurysm is rare but fatal. It is, therefore, essential to determine the location of an aneurysm and provide immediate surgical or the interventional treatment. We report a case of spotaneous hemothorax caused by rupture of an intercostal arterial aneurysm diagnosed by CT and angiography.

    Over the period from January 2002 to March 2005, a total of 78 patients were operated on for DeBakey type I aortic dissection. Of these, five patients underwent prosthetic reconstruction of the aortic arch and brachiocephalic arteries (BCA), performed with the help of the Dacron prosthesis Gelweave four-branch plexus Vascutek. The major indication for using this prosthesis was the extending of the dissection into the BC As, with various degree of obstruction thereof. The overwhelming majority of the patients were men (80 %). The patients' average age amounted to 44.3+/-5.6 years (ranging from 36 to 57 years). In three cases, the aortic dissection was of chronic course, with acute and subacute dissection being diagnosed in the remaining two cases. The median-sternotomy access, and additional approaches to the left and right common carotid arteries were used in order to carry out prosthetic reconstruction of the ascending branch, aortic arch, right subclavian artery, right common carotid artery (CCA) and left CCA with the help of the multiple-branch prosthesis. Protection of the brain consisted of craniocerebral hypothermia, hypothermal circulatory arrest in a combination with retrograde cerebral perfusions through the vena cava superior. The duration of the circulatory arrest averagely amounted to 59.2+/-4 min, with the mean time of artificial circulation equalling 230.6+/-19.7 min, and the time of aortic occlusion was 193.1+/-11 minutes. None of the patients developed either neurological or haemorrhagic complications postoperatively. Hence, the surgical technique using multiple-branch prostheses for prosthetic reconstruction of the aortic arch in type I aortic dissection with BCA obstruction proved to be effective and safe.

    To study the causes and value of the pseudo-occlusion of the anastomotic pathway between celiacand superior mesenteric arteries. Methods: 15 patients including 12 patients with hepatocellular carcinoma and 3 patients withhepatic hemangioma underwent superior mesenteric arteriography (SMA) and celiac arteriography (CA) in interventional thera-py. The angiographic features of the 15 cases were dynamically observed by 2 experienced radiologists in double-blind manner.Results: Similar interpretations were given by the 2 radiologists. In CA,pseudo-ooclusion occurred at the bifurcation of thecommon hepatic artery and the celiac artery in 8 cases, at the bifurcation of the common hepatic artery and the gastroduodenalartery in 6 cases and at the bifurcation of the right hepatic artery and the celiac artery in 1 case. No occlusion was found inSMA and the angiographic wire and catheter could pass easily through the occluded regions seen in CA. Conclusion: Pseudo-occlusion of the anastomotic pathway between the superior mesenteric and celiac arteries is rare phenomenon. Its cause was notidentified in our cases. It may result from the hemodynamic change or abnormality of the hepatic artery. It is very important tounderstand the existence of pseudo-occlusion in order to guide the catheterization in interventional therapy.

    Full Text Available Background: The circle of Willis is a large arterial anastomotic ring present at the base of the brain uniting the internal carotid and the vertebrobasilar systems. Branches from the internal carotid and vertebral arteries anastomose to form an arterial circle in the basal cisterns and then distribute to supply the brain. The anatomy of the circle is known to vary significantly; the vessels may be absent or sufficiently narrowed altering the hemodynamics of the circle of Willis and affecting its role as a collateral route. These variant forms can be correlated to their phylogeny and embryology. Prior knowledge of these variant forms is important in pathologies and treatment (e.g. parent artery occlusion for carotid aneurysms resulting occlusion of carotid and vertebral arteries. Context and purpose: Our study was undertaken to observe and compare the morphology of circle of Willis using two entirely different methods; gross dissection (GD and Magnetic resonance angiography (MRA and to correlate the variant patterns encountered with the possible underlying developmental events. Gross dissection was carried out in 70 human cadavers and equal numbers of MRA’s of healthy individuals were studied retrospectively. Results: Only 31 cases (22.14% presented with a complete circle of Willis, out of which 14 (20% were cadaveric specimen and 17 (24.18% were in MRA group. Unilateral hypoplastic posterior communicating artery was the most common variation observed in our study (19.28%. Conclusions: The wide variation in completeness of the circle of Willis in general population is similar to earlier observations. Review of phylogeny and embryology makes us familiar with variant forms which would be otherwise difficult to recognize and may be misinterpreted. MRA and gross dissection findings despite certain variations are comparable.

    Full Text Available Transcutaneous lead extraction can be associated with significant morbidity and mortality. The risk of causing concomitant arterial and venous injury is rare. We report a case of marginal artery rupture with coronary sinus rupture after a CS lead extraction. A 71-year-old male was admitted for extraction of a 6-year-old implantable cardioverter-defibrillator lead due to fracture from insulation break. During the lead extraction, blood pressure fell precipitously and echocardiographic findings were consistent with pericardial effusion. After unsuccessful pericardiocentesis, open chest sternotomy and evacuation of hematoma was performed. Subsequent surgical repair of several injuries was completed including the distal coronary sinus, a large degloving injury of posterior portion of the heart, and first obtuse marginal branch bleed. This case demonstrates that when performing transcutaneous lead extraction (TLE with laser sheath, a degloving injury can cause arterial rupture with concomitant coronary sinus injury. A multidisciplinary team-based approach can ensure patient safety. Learning Objective. Implantable cardioverter-defibrillator leads will falter over time. With the advancement of new technology for extraction more frequent and serious complications will occur. Active fixation CS leads present unique challenges. In the presence of hemodynamic changes during extraction the occurrence of both an arterial and venous injury must be considered.

    Full Text Available Background. Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS remains the main focus of debate. Case Series. We present three cases, all presenting to our facility within one week’s time, of patients with newly discovered anomalous origination of the left coronary artery from the right sinus of Valsalva (L-ACAOS. All patients underwent cardiac computed tomography for evaluation of coronary anatomy along with other forms of functional testing. Despite the high risk nature of two of the anomalies, the patients are being treated medically without recurrence of symptoms. Summary. After review of the literature, we have found that the risk of sudden cardiac death in patients with congenital coronary anomalies, even among variants considered the highest risk, may be overestimated. In addition, the exact prevalence of coronary anomalies in the general population is currently underestimated. A national coronary artery anomaly registry based on cardiac computed tomography and invasive coronary angiography data would be helpful in advancing our understanding of these cardiac peculiarities. The true prevalence of congenital coronary anomalies and overall risk of sudden cardiac death in this population are not well known. Surgical intervention remains the mainstay of therapy in certain patients though recent investigations into the pathophysiology of these abnormalities have shown that the risk of surgery may outweigh the minimal reduction in risk of sudden cardiac death.

    Full Text Available A mobile thrombus in the carotid arteries is a very rare ultrasonographic finding and is usually diagnosed after a neurological emergency, such as a transient ischemic attack or cerebral infarction. We present the case of a 54-year-old man with vascular risk factors (a heavy smoker, untreated hypertension who was admitted to the emergency unit with right sided hemiparesis and aphasia. A cerebral CT scan showed a left middle cerebral artery territory infarction. The duplex ultrasound examination revealed mild atherosclerotic changes in the right common and internal carotid arteries, right-sided complete subclavian steal phenomenon and a complicated hypoechoic atherosclerotic plaque in the left common carotid artery with a large mobile thrombus. Due to the high embolization risk, the patient was hospitalised and prescribed Aspirin together with low molecular weight Heparin. We recorded an improvement in the patient’s neurological status and the control duplex scan revealed disappearance of the thrombus. The presence of floating thrombus in a patient with clinical and imagistic evidence of stroke is a major therapheutic challenge for the neurologist. The treatment strategies are not standardized and must be individualized, however in our case parenteral anticoagulation proved to be successful.

    We report a case of preoperative embolization in a 64-year-old patient suffering from total stiffness of the right hip joint due to heterotopic ossification following brain injury and pertrochanteric fracture of the right femur. A previous attempt of operative treatment could not be performed successfully due to bleeding complications. After the embolization of the correlating hypervascularisation, the surgical procedure was redone and finished with good result and minimal bleeding complications during the operation and a tolerable drop of the haemoglobin concentration postoperatively.

    Liposarcoma of the esophagus is very rare. We experienced a huge (27.5 × 11.6 cm) liposarcoma of the esophagus. A 73-year-old man presented with severe dyspnea requiring emergency tracheal intubation. Computed tomography and esophagogastroduodenoscopy showed a large submucosal tumor arising from the esophageal entrance and extending intraluminally to the lower esophagus. We successfully performed endoscopic submucosal dissection (ESD) and esophagotomy to remove the tumor, which preserved swallowing and phonation. The final diagnosis by histopathologic and immunohistologic examination was well-differentiated liposarcoma of the esophagus. Treatment by the combination of ESD and esophagotomy can be performed even for a very large tumor. This method preserves deglutition with a lower risk of recurrent laryngeal nerve paralysis than that with esophagectomy.

    2016-07-19

    Blunt vessel injuries of peripheral arteries caused by a direct trauma are rare. Studies have described the frequency of arterial ruptures following closed elbow dislocations in 0.3-1.7% of all cases. However, arterial damage does not always necessarily appear as a complete rupture of the vessel with a loss of peripheral circulation and ischaemic symptoms; a relatively strong periarticular system of collaterals can maintain circulation. Furthermore, the traumatic dislocation can also cause intimal tears, arterial dissections and aneurysms or thrombosis. In all cases of vessel injury, including total disruption, a peripheral pulse might still be palpable. 3 weeks after an acute elbow dislocation, we have diagnosed a patient with a long-segment stenosis of the brachial artery and a thrombosis of the radial artery. Therefore, the close anatomic proximity to the neurovascular structures should always be considered in cases of elbow dislocations, even if peripheral pulses are traceable.

    Horner syndrome, in which ptosis, miosis, and anhidrosis occur concomitantly, can arise from injury to the sympathetic nerve pathways anywhere from the brain to the end organs. Incomplete Horner syndrome lacks the sign of anhidrosis. We present a case of incomplete Horner syndrome caused by internal carotid artery dissection and provide a road map of the cervical sympathetic nerves involved in Horner syndrome to explain its etiology. We also discuss the imaging of and therapy for internal carotid artery dissections.

    We report a rare case of postoperative pseudoaneurysm of the gastroduodenal artery following radical gastrectomy.Surgical trauma to the gastroduodenal artery during regional lymphadenectomy was considered as the cause of the postoperative pseudoaneurysm. The pseudoaneurysm was successfully managed by ligating the bleeding vessel. We should consider the possibility of pseudoaneurysm formation in a patient with gastrointestinal bleeding in the postoperative period following radical gastrectomy with regional lymph node and perivascular lymphatic dissection.

    Full Text Available Background: Retinal arterial macroaneurysms (RAM is a pathological dilatation of retinal arterial vessel. Argon laser photocoagulation has been for a long time the gold standard of many vascular diseases of the retina such as macroaneurysm. From this work emerges how the introduction of intravitreal anti-VEGF therapies have enhanced the 'effectiveness of the combination of argon laser photocoagulation in cases of persistent retinal edema, we present the case of a retinal macroaneurysm with macular hemorrhage focus and oedema in a patient with a history of systemic arterial hypertension. Methods: A 77 year-old woman patient reported sudden decline in visual acuity in the left eye; the best corrected visual acuity (BCVAwas 1/10 in left eye. Fluorescein angiography (FAG resulted in diagnosis of Macroaneurysm at the posterior pole with macular hemorrhage focus and oedema. The patient was treated with laser treatment in the left eye; after 30 days, the visual acuity was 1/50 and at optical coherence tomography (OCT the retinal profile was significantly altered. After 30 days, a single intravitreal ranibizumab injection was performed and, after 7 days, visual acuity was 1/10. After 24 months from ranibizumab-based therapy the final visual acuity was 10/10 and OCT examination revealed a normal retinal profile. Conclusion: In this case report the association of argon laser photocoagulation with intravitreal anti-VEGF injection has been proven to be effective and safe in case of persistent retinal oedema.
