    Full Text Available Blunt injury to the neck region may lead to carotid artery dissection and cerebral ischemia. Blunt injury to carotid artery is not frequent but determination of the presence of trauma in the history of stroke patients will provide early diagnosis and treatment of them. In this article, a case with cerebral ischemia resulting from traumatic carotid artery dissection is presented and clinical findings, diagnostic procedures and choice of treatment are discussed in the light of the literature.

    In the present study, a case of acute cerebral infarction with radiation-induced carotid artery dissection is reported. Carotid artery dissection is generally asymptomatic at the early stages. Due to the non-specific clinical manifestations of carotid artery dissection, a detailed inquiry of the past history of a patient has a critical role in making a diagnosis of radiation-induced common carotid artery dissection. Onset of acute ischemic stroke is the predominant manifestation, and for patients with a history of head-and-neck radiotherapy, dissection should be considered. The condition may progress rapidly, and result in a poor prognosis. Therefore, a correct early diagnosis and initiation of appropriate therapy may lead to rapid recovery, and influence the overall prognosis.

    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.

    Acute dissection of the thoracic aorta is a well-recognized, often fatal condition that frequently extends to involve the abdominal aorta and iliac vessels. The ostia of the renal and mesenteric vessels may be compromised, and the resulting visceral ischemia may necessitate surgical intervention. However, visceral perfusion may be restored if blood flow from true to false lumen is re-established or if the false lumen is obliterated, either spontaneously or by surgical or interventional techniques. Isolated dissections of mesenteric, renal, and carotid vessels are rarely reported. These may be spontaneous, related to high blood pressure and underlying disease of the vessel wall, or caused by abdominal trauma or medical intervention, including angiographic procedures. They are usually associated with pain and other signs and symptoms of ischemia in the appropriate territory. We present a case of chronic superior mesenteric artery (SMA) dissection, an incidental angiographic finding, in an asymptomatic patient being evaluated for resection of an abdominal aortic aneurysm (AAA).

  7. Differential imaging features of pulmonary artery dissection from other intraluminal diseases of pulmonary artery: Two cases report

    International Nuclear Information System (INIS)

    Pulmonary artery dissection is rarer than other intraluminal diseases of pulmonary artery such as pulmonary thromboembolism or pulmonary artery sarcoma. We report two cases of pulmonary artery dissection mimicking pulmonary artery sarcoma. Computed tomography (CT) showed no enhancement of intrapulmonary arterial lesion or expansion of involved pulmonary artery. Magnetic resonance imaging (MRI) showed low-signal intensity intimal flap on T1- and T2-weighted images. There was no fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET)-CT. In this case report, we describe the imaging features of pulmonary artery dissection on CT, MRI, and PET-CT.

    Full Text Available Spontaneous coronary artery dissection (SCAD is an unusual cause of acute coronary syndrome or sudden cardiac death. SCAD has most frequently been described as presenting as an acute coronary syndrome in females during the peripartum period. It may also be associated with autoimmune and collagen vascular diseases, Marfan′s syndrome, chest trauma, and intense physical exercise. The most common presentation of SCAD is the acute onset of severe chest pain associated with autonomic symptoms. This condition has a high mortality rate if not identified and treated promptly. Here, we present a case of SCAD presenting with stroke, followed by a brief review.

    The authors report a case of early peripartum myocardial infarction resulting from spontaneous dissection of the left anterior descending coronary artery and right coronary artery in a twenty-four-year-old woman. This is the first report of double-vessel coronary dissection involving both the left and right coronary arteries diagnosed antemortem and successfully treated.

  11. Treatment of internal carotid artery dissections with endovascular stent placement: report of two cases

    International Nuclear Information System (INIS)

    Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma-related extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpetrosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed

    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.

    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.

    Cerebral arterial dissection is defined as a hematoma in the wall of a cervical or an intracranial artery. Cerebral arterial dissection causes arterial stenosis, occlusion, and aneurysm, resulting in acute infarction and hemorrhage. Image analysis by such methods as conventional angiography, computed tomography, magnetic resonance imaging, and so on plays an important role in diagnosing cerebral arterial dissection. In this study, we explore the methods and findings involved in the diagnosis of cerebral arterial dissection. PMID:27180630

    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.

  5. Tortuous Common Carotid Artery: A Report of Four Cases Observed in Cadaveric Dissections

    2016-01-01

    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.

    Full Text Available Introduction. Left main coronary artery dissection is a rare and potentially life-threatening complication of coronary angiography and angioplasty which requests urgent revascularization. Case report. During the period between 2010 and November 2014 at single healthcare center we did totally 8,884 coronary procedures, out of which 2,333 were percutaneous coronary interventions (PCI. In this period we had a total of 3 (0,03% left main coronary artery dissections, and all of them were successfully treated by PCI. We presented three cases with iatrogenic dissection of the left main coronary artery, occurred during elective diagnostic procedures, successfully treated with PCI with different techniques. Conclusion. PCI could be fast and life-saving approach in iatrogenic dissections of the left main coronary artery.

    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.

    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.

    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.

    2004-05-01

    Full Text Available Abstract Background Medical management is the conventional treatment for Stanford Type B aortic dissections as surgery is associated with significant morbidity and mortality. The advent of endovascular interventional techniques has revived interest in treating end-organ complications of Type B aortic dissection. We describe a patient who benefited from endovascular repair of renal artery stenosis caused by a dissection flap, which resulted in reversal of his end-stage renal disease (ESRD. Case presentation A 69 y/o male with a Type B aortic dissection diagnosed two months earlier was found to have a serum creatinine of 15.2 mg/dL (1343.7 μmol/L on routine visit to his primary care physician. An MRA demonstrated a rightward spiraling aortic dissection flap involving the origins of the celiac artery, superior mesenteric artery, and both renal arteries. The right renal artery arose from the false lumen with lack of blood flow to the right kidney. The left renal artery arose from the true lumen, but an intimal dissection flap appeared to be causing an intermittent stenosis of the left renal artery with compromised blood flow to the left kidney. Endovascular reconstruction with of the left renal artery with stent placement was performed. Hemodialysis was successfully discontinued six weeks after stent placement. Conclusion Percutaneous intervention provides a promising alternative for patients with Type B aortic dissections when medical treatment will not improve the likelihood of meaningful recovery and surgery entails too great a risk. Nephrologists should therefore be aggressive in the workup of ischemic renal failure associated with aortic dissection as percutaneous intervention may reverse the effects of renal failure in this population.

  13. Cervical artery dissection following a turbulent flight.

    LENUS (Irish Health Repository)

    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.

    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.

    Bilateral internal carotid artery dissection is a rare entity, and its presentation may include cerebral ischemia. We describe the case of a 69-year-old man with ischemic stroke and radiological evidence of intimal flap of both internal carotid arteries suggestive for dissection. During the hospitalization, our patient was found positive for a previous syphilis infection. We conducted a review of the literature, with evidence of a few cases of ischemic stroke presumably related to a prior syphilis. The absence of major cardiovascular risk factors in our patient leads us to believe that an etiopathogenetic link may exist between these two conditions. PMID:27354805

    Full Text Available Abstract Introduction Basilar artery dissection is a rare occurrence, and is significantly associated with morbidity and mortality. To the best of our knowledge, we report the first case of basilar artery dissection treated with mesenchymal stem cells. Case presentation We present the case of a 17-year-old Korean man who was diagnosed with basilar artery dissection. Infarction of the bilateral pons, midbrain and right superior cerebellum due to his basilar artery dissection was partially recanalized by intrathecal injection of human umbilical cord blood-derived mesenchymal stem cells. No immunosuppressants were given to our patient, and human leukocyte antigen alloantibodies were not detected after cell therapy. Conclusions This case indicates that intrathecal injections of mesenchymal stem cells can be used in the treatment of basilar artery dissection.

    Percutaneous coronary intervention (PCI) as a treatment of coronary artery disease can be a simple, rapid procedure with a clear benefit for the patient, but it could also become a complex procedure with fatal consequences. These complications depend on the lesion itself, material used and also on operating staff. In this case we report a coronary artery dissection of the circumflex (CX) artery caused by inflation of an oversized balloon. We discuss here the management and evolution of this complication.

  20. 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.)

    Abstract Background The use of antithrombotic therapy (anticoagulants and/or antiplatelets) in the setting of traumatic cervical arterial dissection (CAD) for the prevention of stroke remains controversial. This issue is further complicated by the frequent co-existence of intracranial hemorrhage (ICH) and other intracranial injuries, and also the wide variability in treatment due to a lack of evidence-based guidance. To address these controversies, a registry in a major Level I trauma center ...

    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

    Dissecting aneurysms of the posterior cerebral artery (PCA) are rare, especially those at the P1 segment. Here, we describe the case of a 57-year-old woman with a subarachnoid hemorrhage (SAH). Computed tomography angiography (CTA) and digital subtraction angiography (DSA) revealed a small (3 mm) dissecting aneurysm with the typical pearl-and-string sign at the right P1 segment. Fourteen days after onset, the patient developed aphasia. DSA revealed vasospasm of the right middle cerebral artery, and we performed endovascular treatment by the intra-arterial injection of 1-(5-isoquinolinesulfonyl) homopiperazine. After this treatment, the patient's symptoms recovered immediately. Vertebral angiography revealed enlargement of the dissecting aneurysm (up to 7 mm diameter). We started a loading dose of 300 mg aspirin and 400 mg clopidogrel after observing growth of the aneurysm. Fifteen days after onset, we performed a stent-assisted coil embolization, and obtained nearly complete obliteration of the aneurysm with preserved patency of the parent artery. Six-month follow-up DSA demonstrated complete occlusion of the aneurysm with good patency of the stented PCA; the patient was at modified Rankin Scale 1. In the treatment of ruptured dissecting aneurysms, parent vessel occlusion (PVO) with aneurysm is common. However, PVO may cause both cerebral infarction of the distal area and perforator occlusion of the occluded vessel. Stent-assisted coil embolization can preserve parent vessel flow and obliterate the aneurysm. Stents offer a therapeutic alternative for PCA dissecting aneurysms, especially when PVO cannot be tolerated. PMID:26646176

    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.

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

    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."

    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.)

    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.

    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.

  13. Brainstem ischemic stroke without permanent sequelae during the course of spontaneous internal carotid artery dissectioncase report

    International Nuclear Information System (INIS)

    Internal carotid artery dissection (ICAD) is a frequent cause of a stroke in young patients. Risk factors which can lead to dissection include neck injury and diseases of the inner wall of the artery. Common symptoms in ICAD are cervical pain and headache, Horner’s syndrome, paralysis of the cranial nerves and subsequently cerebral and retinal ischemia. MR angiography in TOF technique and brain MRI in T1- and T2-weighted images, FLAIR and DWI sequences are the method of choice in patients with ICAD but contrast-enhanced multislice computed tomography remains the fastest and the most available diagnostic method. A 39-year old woman, previously healthy, presented to the Hospital Emergency Department because of increasing neck pain on the right side and difficulty in swallowing. The neurological examination revealed: drooping of the right eyelid with narrow palpebral fissure, dysarthria, anisocoria (narrower pupil on the right side), unilateral hypoesthesia on the left side, weak palatal and pharyngeal reflexes on both sides, paresthesia within the left half of the body. Seven days before, the patient felt a sudden, severe neck pain radiating to the temporal apophysis. CT angiography revealed a defect in contrast filling within the left internal carotid artery and right vertebral artery. MRI of the head with MR angiography showed internal carotid artery dissection on the left side and dissection of the right vertebral artery and no ischemic changes within the brain. CT and MR angiography are methods characterized by high sensitivity in detecting dissection of the cervical arteries

    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.

    2012-01-01

    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 In recent years, vertebral artery dissection (VAD is reported more frequently as a cause of young cerebrovascular accidents. It can occur spontaneously or following a neck manipulation and trauma. The patients were 3 females (mean age: 35±26 years and 7 males (mean age: 37.71±4.96 years. Only 2 patients described neck trauma. Cerebellar findings were prominent in all cases. On radiological investigation, vascular changes of vertebral arteries were detected bilaterally in 2 cases, right in 5 and left in 3 cases. All the cases were treated with anticoagulant therapy and cured but 1 with sequela. Prognosis of vertebral artery dissection is generally good by early diagnosis and treatment. In this article, we reported clinical and radiological properties of 10 vertebral artery dissection cases.

    Spontaneous coronary artery dissection (SCAD) is gaining recognition as an important cause of myocardial infarction, especially in young women. There has been a surge in the diagnosis of SCAD in recent years, presumably due to an increased use of coronary angiography, and the clinical availability and application of high-resolution intracoronary imaging. The improved recognition and diagnosis, together with increased publications and attention through social media, have considerably raised awareness of this condition, which was once believed to be very rare. Recent publications of moderate to large contemporary case series have helped elucidate the early natural history, presenting characteristics (clinical and angiographic), underlying etiology, management, and cardiovascular outcomes with this condition, thus providing observations and important clinical insights of value to clinicians managing this challenging and perplexing patient cohort. The aim of our review is to provide a comprehensive contemporary update of SCAD to aid health care professionals in managing these patients in both the acute and chronic settings. PMID:27417009

    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.

    Cervical artery dissection (CAD) represents an increasingly recognized cause of stroke and the most common cause of ischemic stroke in young adults. Many factors have been identified in association with CAD such as primary disease of arterial wall (fibrodysplasia) and other non-specific diseases related to CAD like Ehlers Danlos-syndrome IV, Marfan’s syndrome, vessel tortuosity. Moreover, an underlying arteriopathy which could be in part genetically determined, has been suspected. The rule of...

    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.

    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.

    A 41-year-old man with hypertension and hyperlipidemia who complained of left hemiparesis after a temporal headache was admitted to our hospital. A cervical MRI with gadolinium enhancement revealed an intramural hematoma is compatible with right extracranial internal carotid artery dissection. Two weeks later, he complained of sudden onset of pain in the right side of his neck. The right extracranial internal carotid artery dissection followed by the right extracranial vertebral artery dissection was diagnosed. Spontaneous cervical artery dissection (SCAD) is one of the causes of stroke in young adults. The pathogenesis of SCAD remains unknown. Minor trauma like an excessive sneeze, migraine, and connective tissue disorders such as fibromuscular dysplasia and Ehlers-Danlos syndrome are well-known as risk factors for SCAD. Pathologically skin collagen abnormalities have been seen in German patients with SCAD without clinical evidence for any specific connective tissue disorder. We examined the ultrastructural morphology of the Japanese patient's dermal connective tissue components by electron microscopy. The patient's collagen fibers contained fibrils with highly variable diameters, and there were other ultrastructural abnormalities, including flower-like fibrils and large-diameter composite fibrils. This is the first report of a case of ultrastructural abnormalities of dermal connective tissue in a Japanese patient with SCAD. PMID:16619839

    Child abuse is often suspected based on particular patterns of injury. We report a case of intracranial vertebral artery dissection with subarachnoid hemorrhage (SAH) in a 3-month-old boy following child abuse. The mechanisms of injury and the clinical and imaging findings are discussed. This particular pattern of injury has rarely been reported in association with child abuse. We hope to raise physician awareness of child abuse when faced with these imaging findings. (orig.)

  12. Bilateral Carotid Artery Dissection after High Impact Road Traffic Accident

    2008-11-01

    Full Text Available A 58 year old man was involved in a high impact road traffic incident and was admitted for observation. Asymptomatic for the first 24 hours, he collapsed with symptoms and signs consistent with a cerebrovascular accident. Computed tomography angiogram (CTA and Magnetic resonance angiogram (MRA demonstrated bilateral internal carotid artery dissections and a left middle cerebral artery infarct. It was not considered appropriate to attempt stenting or other revascularistation. The patient was treated with heparin prior to starting warfarin. He made a partial recovery and was discharged to a rehabilitation facility. This case is a reminder of carotid dissection as an uncommon but serious complication of high speed motor vehicle accident, which may be silent initially. Literature Review suggests risk stratification before relevant radiological screening at risk patients. Significant advances in CTA have made it the diagnostic tool of choice, but ultrasound is an important screening tool.

    Full Text Available Background and Purpose: Emphasizing the therapeutic and diagnostic implications of concomitant inadequate collaterals from the circle of Willis in a rare case of spontaneous acute bilateral internal carotid artery dissection (BICAD following 5 days of isolated rigorous cough (pertussis like. Case Description: A 45-year-old male has been referred to our department with rapid neurological deterioration consisting of dysarthria and severe left hemiparesis following 5 days of isolated rigorous cough. CTA demonstrated BICAD, a tiny anterior communicating artery and no bilateral posterior communicating artery. The patient had no personal or familial risk factors. Infectious, traumatic, vascular and connective tissue diseases were ruled out. Results: Neurological deterioration persisted despite immediate provision of continuous ‘full-heparinization’ with concomitant rigorous control of blood pressure. Endovascular treatment consisting of bilateral stenting was undertaken. Ten days later, the patient was discharged with mild hemiparesis and resuming normal activity after 3 months. Conclusions: BICAD with concomitant inadequate collaterals from the circle of Willis may predispose to hypoperfusion which might not respond to the usual conservative treatment prompting for flow reestablishment. Moreover, isolated rigorous cough can cause acute spontaneous BICAD even among patients without any risk factors.

  14. 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 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.

    Background: Multivessel cervical dissection with cortical sparing is exceptional in clinical practice. Case presentation: A 55-year-old man presented with acute-onset neck pain with associated sudden onset right-sided hemiparesis and dysphasia after chiropractic manipulation for chronic neck pain. Results and Discussion: Magnetic resonance imaging revealed bilateral internal carotid artery dissection and left extracranial vertebral artery dissection with bilateral anterior cerebral artery territory infarctions and large cortical-sparing left middle cerebral artery infarction. This suggests the presence of functionally patent and interconnecting leptomeningeal anastomoses between cerebral arteries, which may provide sufficient blood flow to salvage penumbral regions when a supplying artery is occluded. Conclusion: Chiropractic cervical manipulation can result in catastrophic vascular lesions preventable if these practices are limited to highly specialized personnel under very specific situations.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction. The disease is usually seen in young-middle aged women and leads to sudden death in the majority of cases. In survived patients, diagnosis of SCAD has been made with coronary anjiography. Involvement of left main coronary artery (LMCA is very unusual. We describe on a case of SCAD involving the LMCA in a young woman presenting with an acute myocardial infarction and cardiogenic shock status. There were no risk factors for coronary artery disease and no evidence of atherosclerosis on angiography. Coronary angiography revealed dissection of the LMCA that extended into the anterior descending and circumflex coronary arteries. The dissection was successfully treated with primary coronary artery stenting. The patient was discharged without complication. There was no problem in the first evaluation at the end of the first of the month. J Clin Exp Invest 2011; 2 (3: 299-303.

    When approaching the symptom of acute onset chest pain in a previously healthy 26-year-old male, anchoring heuristic presents a challenge to healthcare workers. This diagnostic error is the healthcare professional's tendency to rely on a previous diagnosis, and, in situations where a set of symptoms might mask a rare and deadly condition, this error can prove fatal for the patient. One such condition, Spontaneous Coronary Artery Dissection (SCAD), is an uncommon and malefic presentation of coronary artery disease that can lead to myocardial infarction and sudden death. We present a case of SCAD in an otherwise healthy 26 year-old male who had been experiencing chest pain during and after sports activity. In the young, athletic male with SCAD, the danger of diagnostic error was a reality due to the broad symptomatology and the betraying demographics. PMID:25945264

  7. Recanalization of occlusive extracranial internal carotid artery dissection through medication of anticoagulant and antiplatelet agents: report of two cases with literature review

    International Nuclear Information System (INIS)

    Objective: To determine the effectiveness and safety of antiplatelet and anticoagulant agents in the treatment of extracranial internal carotid artery dissection (eICAD). Methods: Antiplatelet and anticoagulant agents were adopted to treat two cases of eICAD in our hospital. The clinical data were retrospectively analyzed and the medical literatures concerning eICAD, which were obtained from Pubmed database, were reviewed. Results: Most researches advocated the empirical use of antiplatelet and anticoagulant agents in eICAD. About 30% of occluded eICAD could be reopened in 8 days and about 60% - 80% in 3 months after the onset of the disease. During the period of treatment, the rate of ischemic stroke recurrence, disability or death was 8.3%-14.3% in anticoagulant group, while it was 7% - 23.7% in antiplatelet group. Conclusion: Antiplatelet agents can be used in patients with eICAD who are contraindicated to anticoagulants. Anticoagulants should be used as early as possible in patients who are not contraindicated to anticoagulants. (authors)

    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.

  9. Vertebral artery dissection due to indirect neck trauma : an underrecognised entity.

    Directory of Open Access Journals (Sweden)

    Prabhakar S

    2001-10-01

    Full Text Available Vertebral artery dissection is an important cause of brain stem stroke, especially in the young. 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.

  10. A study of the treatment method of cerebral artery dissection

    International Nuclear Information System (INIS)

    Objective: To explore the best treatment method of cerebral artery dissection. Methods: This study included eight patients who were definitely diagnosed as cerebral artery dissection by the cerebral angiography in our department of neurology during Oct. 2009 and Nov. 2011. They were all treated by the anticoagulation or anti-platelet methods. Some patients received the stent therapy. All patients' were followed for at least three months. The treatment effect was assessed by NIHSS, mRS and by the cerebral angiography. Results: Six patients had carotid artery dissection, 2 had vertebral artery dissection. Four patients were given anticoagulant therapy and the other 4 were given anti-platelet therapy. The reexamination by angiography 10-14 days after admission showed that in 3 patients, the stenosis was aggravated or the infarction occurred. They were diagnosed as having repeated transient ischemic attack (TIA) during pharmacotherapy and received stents for treatment. There was no TIA and cerebral infarction in the follow-up period after individualized therapy. Mean NIHSS scores of 8 patients between pre and post treatment were 5.9, 1.6 respectively. Mean mRS scores pre and post treatment were 2.5, 0.9 respectively. Conclusion: The treatment for patients with cerebral artery dissection should be individuated. The patients in acute stage should get anticoagulation, anti-platelet therapy and angiography re-examination. According to the clinical manifestation and cerebral angiography, the next step for the treatment should be done. (authors)

    Full Text Available Abstract Background We report an intraoperative retrograde dissection of the aorta and its subsequent evaluation by transesophageal echocardiography (TEE. Case presentation A 78 year old woman with an ascending aortic aneurysm without dissection and coronary artery disease was brought to the operating room for aneurysm repair and coronary artery bypass grafting. After initiation of cardiopulmonary bypass through a femoral artery cannula, aortic dissection was noted and subsequently imaged by TEE. Conclusion Retrograde aortic dissection through the femoral artery is life-threatening. Intraoperative TEE can be used to diagnose this uncommon event, and should be considered after initiation of bypass.

    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.

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

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ 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.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction. The disease is usually seen in young-middle aged women and leads to sudden death in the majority of cases. In survived patients, diagnosis of SCAD has been made with coronary anjiography. Involvement of left main coronary artery (LMCA) is very unusual. We describe on a case of SCAD involving the LMCA in a young woman presenting with an acute myocardial infarction and cardiogenic shock status. There w...

    Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, and thoracotomy causing significant morbidity and mortality rates. Endovascular techniques may offer an alternative to these surgically demanding procedures. We present a patient with a traumatic dissection of the axillary artery following anterior shoulder dislocation who was successfully managed with an endovascular stent. PMID:18411587

  18. Dissection of internal carotid and vertebral arteries: clinical presentation, diagnosis, and treatment

    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.

    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.)

    Spontaneous coronary artery dissection is a rather rare cause of myocardial infarction, chest pain, and sudden death. Since the condition was first described in 1931, fewer than 200 cases have been reported in the medical literature. There are currently no known direct causes of this condition, although some correlations have been noted. Many patients are women in the peripartum period or of childbearing age, with few or no risk factors for coronary artery disease. Other associations include contraceptive use and connective-tissue disorders, Ehlers-Danlos and Marfan syndromes, and polyarteritis nodosa. Most of the reported dissections have occurred in the left anterior descending coronary artery. Herein, we report the case of a 36-year-old woman who presented at our institution with an acute ST-elevation myocardial infarction secondary to a spontaneous dissection of the right coronary artery. Thrombectomy and stenting resolved the occlusion of the artery, and the patient was discharged from the hospital on medical therapy. We discuss the pathophysiology, presentation, and treatment of this rare and often fatal condition. PMID:22412239

    A-68-year-old man experienced nuchal pain and bilateral shoulder weakness that occurred suddenly after he performed a golf swing. He was conscious. His cranial nerves were normal, but bilateral deltoid and biceps muscle strengths weakened. Magnetic resonance image (MRI) showed no brain stem infarctions or cervical epidural hematoma. We tentatively diagnosed him with concussion of the spinal cord because of mild recovery of his bilateral upper limb weakness after several hours; he was later discharged. The next day, he suddenly developed serious tetraplegia and was admitted to the emergency department. His breathing was controlled by a respirator as he had expectoration difficulty and respiratory muscle paralysis. A lesion in the cervical cord became apparent on MRI; the right vertebral artery was not detected on magnetic resonance angiography. Cervical MRI showed the intimal flap and a lack of flow void in the right vertebral artery. These findings revealed a right vertebral artery dissection. Cervical cord infarction due to unilateral vertebral artery dissection is rarer than posterior cerebral infarction due to the same pathogenesis; however, some such cases have been reported. We consider the present case to be caused by cervical cord infarction associated with unilateral vertebral artery dissection resulting from golf swing. PMID:24583591

    Full Text Available Background: The endovascular strategy of the huge dissecting aneurysms involving the basilar artery (BA is controversial and challenging. This study was to investigate the clinical and angiographic outcomes of the treatment of the huge dissecting aneurysms involving the BA by the internal trapping (IT technique. Methods: We retrospectively studied 15 patients with the huge dissecting aneurysms involving the BA treated by the IT technique between September 2005 and September 2014 in Department of Interventional Neuroradiology of Beijing Tiantan Hospital. Clinical and angiographic data were reviewed and evaluated. Results: All patients were treated by the IT technique. That meant the dissecting artery and aneurysm segments were completed occlusion. After the procedure, the angiography demonstrated that all the dissecting artery and aneurysm segments were completed occlusion. Follow-up angiography was performed at 3-6 months or 12-18 months after the endovascular treatment (median 8 months, 14 patients had a good recovery. Re-canalization occurred in one patient whose aneurysm involved in bilateral vertebral arteries and the two third of the middle-lower BA. After the second treatment, the patient died by the ventricular tachycardia. Conclusions: The IT technique is a technically feasible and safe alternative for the treatment of BA dissecting aneurysms, but it is not necessarily the safest or most definitive treatment modality. The ideal treatment of the huge dissecting aneurysms involving the BA remains debatable and must be investigated on a case-by-case basis.

    Full Text Available Abstract 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.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. It occurs predominantly among younger females, typically in the absence of atherosclerotic coronary artery disease. Presentations vary greatly and this condition can be fatal. Given its rarity, there are no management guidelines. We present six patients with SCAD with different presentations and treatment approaches as examples in our literature review. Two patients presented with ST elevation myocardial infarction (STEMI), two with non-STEMI (NSTEMI), and two with cardiac arrest. Patients were treated according to the presentation, clinical stability, and extension and distribution of the dissection. Four patients underwent emergent percutaneous coronary intervention (PCI) and one was clinically stable and treated medically initially and underwent an elective PCI after 4 weeks when coronary angiogram showed persistent dissection. Another patient was treated medically as he was hemodynamically stable and the dissection affected a small branch. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was used for diagnosis confirmation as well as during and after PCI to assure good stent apposition. All patients had excellent outcome. SCAD is a rare cause of acute coronary syndrome and a high index of suspicion is crucial for early diagnosis. In patients with early presentation, limited disease, and ongoing symptoms, emergent cardiac catheterization with PCI has excellent outcome. However, in stable patients, medical management and elective PCI in few weeks if the dissection persists is a more reasonable approach. IVUS and OCT are invaluable especially in ambiguous cases.

However it is increasingly reported in these days with the development of advanced imaging technology. Underlying etiology, natural course or an optimal management strategy of SISMAD is not exactly known at the moment. During the past 10 years, we have had an interest in this rare vascular disease and collected clinical and image data in 100 or more patients with SISMAD. In this review article, I would like to describe my current understanding of SISMAD on the base of our recent publications in the major vascular surgery journals. PMID:27386450

    Internal carotid artery dissection (ICAD) with concomitant occlusive intracranial large artery emboli is an infrequent cause of acute stroke, with poor response to intravenous thrombolysis. Reports on the management of this entity are limited. We present our recent experience in the endovascular management of occlusive ICAD and major intracranial occlusion. Consecutive anterior circulation acute stroke patients meeting Medical Center criteria for endovascular management of ICAD from June 2011 to June 2015 were included. Clinical, imaging, and procedure data were collected retrospectively under Institutional Review Board approval. The endovascular procedure for carotid artery revascularization and intracranial stent thrombectomy is described. Six patients met inclusion criteria (National Institutes of Health Stroke Scale score 12-24, time from symptom onset 2-8hours). Revascularization of the extracranial carotid dissection and stent thrombectomy were achieved in 5/6 patients, resulting in complete recanalization (Thrombolysis in Myocardial Infarction flow grade 3 in a mean 2.7hours), and modified Rankin Scale score 0-2 at 90 day follow-up. In one patient, attempts to microcatheterize the true arterial lumen failed and thrombectomy was therefore not feasible. No arterial dissection, arterial rupture or accidental stent detachment occurred, and there was no intracerebral hemorrhage or hemorrhagic transformation. Our preliminary data on this selected subgroup of patients suggest the presented approach is safe, feasible in a significant proportion of patients, and efficacious in achieving arterial recanalization and improving patient outcome. Crossing the dissected segment remains the most important limiting factor in achieving successful ICA recanalization. Further evaluation in larger series is warranted. PMID:26924182

    Full Text Available Traumatic coronary artery dissection is an uncommon cause of acute myocardial infarction (AMI. We report a case of blunt chest trauma resulting from a motorcycle collision causing ostial dissection of the left anterior descending (LAD artery in a 31-year-old previously healthy male. The patient also suffered from compound comminuted fractures of the humerus and ulna and severe liver laceration, which hampered both percutaneous and surgical acute revasularization. After a stormy hospital course, a bare metal stent was implanted to seal the LAD artery dissection. The patient was discharged in a stable condition and was followed-up for rehabilitation. This case report underscores the multidisciplinary approach in facing challenges encountered after rare sequelae of chest trauma.

    2005-01-01

    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

    We report the utility of a pulsed water jet device in meningioma surgery. The presented case is that of a 61-year-old woman with left visual disturbance. MRI demonstrated heterogeneously enhanced mass with intratumoral hemorrhage, indicating sphenoid ridge meningioma on her left side. The tumor invaded the cavernous sinus and left optic canal, engulfing the internal carotid artery in the carotid cistern and encased middle cerebral arteries. During the operation, the pulsed water jet device was useful for dissecting the tumor away from the arteries since it was safe in light of preserving parent arteries. The jet did not cause any vascular injury and did not induce vasospasm as shown by postoperative symptomatology and MRIs. With the aid of pulsed water jet, we could achieve total resection of the tumor except for the piece within the cavernous sinus. The patient had no new neurological deficits after the operation. We consider the pulsed water jet as a useful device, especially when the need to dissect meningioma from parent arteries exists. The jet can help neurosurgeons simultaneously achieve tumor resection and preservation of blood vessels. PMID:25351797

    Unlike vascular Ehlers-Danlos syndrome (EDS), classic EDS is rarely associated with vascular manifestation. We report the case of a 39-year-old man who presented with acute abdominal pain. At the time of presentation, the patient was in hypovolemic shock, and computed tomography angiogram demonstrated common iliac artery dissection with rupture. He underwent an attempted endovascular repair that was converted to an open repair of a ruptured right common iliac artery dissection. Subsequent genetic testing revealed a substitution of arginine for cysteine in type I collagen, COL1A1 exon 14 c.934C>T mutation, consistent with a rare variant of classic EDS. PMID:25597651

    Turner's syndrome (TS) has been documented as the most common cause of aortic dissection in young women. However, little attention from vascular surgery has been paid to these patients. We report the first case of ruptured type B aortic dissection with aberrant right subclavian artery treated successfully with hybrid endovascular and open procedures in a patient with TS. Left carotid to subclavian artery bypass, thoracic endovascular aortic repair, and coil embolization of the aberrant right subclavian and left subclavian arteries were performed in an emergency setting. Literature on epidemiology, causes, and management options of acute aortic dissection in TS patients are reviewed and discussed. PMID:24011806

    Full Text Available True spontaneous coronary artery dissection (SCAD is an extremely rare but important cause of acute coronary syndrome, with only about 200 cases reported in the literature. Diagnosis is often made at autopsy. Risk factors include oral contraceptive use, atherosclerotic disease and the peripartum period. SCAD should be considered when a healthy young patient presents with the onset of acute myocardial ischemic syndrome. A timely diagnosis and intervention are mandatory as SCAD can cause sudden death. We present a case of SCAD with an uncommon clinical presentation of acute coronary syndrome and without identifiable risk factors, and successfully treated with non-invasive (medical therapy.

    Background Spontaneous coronary artery dissection (SCAD) is an uncommon but serious condition presenting as an acute coronary syndrome (ACS) or cardiac arrest. The pathophysiology and outcomes are poorly understood. We investigated the characteristics and outcomes of patients presenting with SCAD. Methods In a retrospective study of a large cohort of patients with SCAD, data were collected regarding clinical presentation, patient characteristics, vascular screening, coronary artery involvement and clinical outcomes. Results 40 patients with SCAD (95% women, mean age 45±10 years) were included. At least 1 traditional cardiovascular risk factor was present in 40% of patients. Migraine was reported in 43% of patients. Events preceding SCAD included parturition (8%), physical stress (13%), emotional stress (10%) and vasoconstrictor substance-use (8%). 65% of patients had a non-ST elevation ACS (NSTEACS) at presentation, 30% had an ST elevation myocardial infarction (STEMI) and 13% had a cardiac arrest. The left anterior descending artery was most frequently involved (68% of patients), and 13% had involvement of multiple coronary territories. Fibromuscular dysplasia (FMD) was identified in 7 (37%) of 19 patients screened. 68% of patients were managed medically, 30% had percutaneous coronary intervention and 5% had coronary artery bypass grafting. Over a median 16-month follow-up period, 8% of patients had at least 1 recurrent SCAD event. There were no deaths. Conclusions Patients with SCAD in this study often had multiple coronary territories involved (13%) and extracardiac vascular abnormalities, suggesting a systemic vascular process, which may explain the high incidence of migraine. All patients with SCAD should be screened for FMD and followed closely due to the possibility of recurrence.

    Full Text Available 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.

    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.

    2010-05-01

    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.

    Basilar artery dissection is a rare disease with high morbidity and mortality. No well-established management strategy exists for this lesion. Endovascular reconstructive therapy using stents (with or without coiling) may be the optimum strategy.We describe our center's experience for this treatment strategy in 21 patients with basilar artery dissection from January 2009 to July 2014 (17 men, four women; age range, 18-70 years; median age, 56 years). We divided patients into two groups: Group 1 patients received stent-assisted coiling treatment, and Group 2 patients received stent-only treatment. Pre-treatment, peri-operation and follow-up evaluation were investigated for complications, clinical outcome and angiographic results. The median follow-up time was 20 months (range, 3-67 months).All patients were treated endovascularly by stent-assisted coiling (14 patients) or stent only (seven patients). Immediate angiography showed: in Group 1, five of 14 lesions were completely occluded, five were partially occluded, four revealed retention of contrast media; in Group 2, all patients (seven of seven) had contrast retention. At the follow-up visit (median seven months, 3-29 months), the aneurysms were angiographically improved in five of 13 patients in Group 1 compared with immediately post-operation, while six of sevenimproved in Group 2. Five patients (all in Group 1) had ischemic or hemorrhage peri-operation complications. Long-term good clinical outcomes (modified Rankin Scale score (mRS) ≤ 2) were achieved in all patients except three death cases (two in Group1, one in Group 2).In our experience, endovascular reconstructive therapy using stents (with or without coiling) for basilar artery dissection is effective and safe. Stent-only treatment seems have a better safety profile during the peri-operation period. PMID:26842610

    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.

    Cervical artery dissection (CeAD) occurs in healthy young individuals and often entails ischemic stroke. Skin biopsies from most CeAD-patients show minor connective tissue alterations. We search for rare genetic deletions and duplication that may predispose to CeAD. Forty-nine non-traumatic CeAD-patients with electron microscopic (EM) alterations of their dermal connective tissue (EM+ patients) and 21 patients with normal connective tissue in skin biopsies (EM- patients) were analyzed. Affymetrix 6.0 microarrays (Affymetrix) from all patients were screened for copy number variants (CNVs). CNVs absent from 403 control subjects and from 2402 published disease-free individuals were considered as CeAD-associated. The genetic content of undentified CNVs was analyzed by means of the Gene Ontology (GO) Term Mapper to detect associations with biological processes. In 49 EM+ patients we identified 13 CeAD-associated CNVs harboring 83 protein-coding genes. In 21 EM- patients we found five CeAD-associated CNVs containing only nine genes (comparison of CNV gene density between the groups: Mann-Whitney P=0.039). Patients' CNVs were enriched for genes involved in extracellular matrix organization (COL5A2, COL3A1, SNTA1, P=0.035), collagen fibril organization COL5A2, COL3A1, (P=0.0001) and possibly for genes involved in transforming growth factor beta (TGF)-beta receptor signaling pathway (COL3A1, DUPS22, P=0.068). We conclude that rare genetic variants may contribute to the pathogenesis of CeAD, in particular in patients with a microscopic connective tissue phenotype. PMID:22617347

  2. Treatment of Intra- and Extracranial Arterial Dissections Using Stents and Embolization

    International Nuclear Information System (INIS)

    Purpose. To evaluate the safety and efficacy of stent placement for extracranial and intracranial arterial dissections. Methods. Eighteen patients underwent endovascular treatment of carotid and vertebral dissections using intraluminal stent placement. Five patients with arterial dissection were treated, 2 using one insertion of a single stent and 3 using placement of two stents. Patients with a dissecting aneurysm were treated as follows: 7 patients with insertion of one stent, 4 with placement of two stents, and 2 by stent-assisted Guglielmi detachable coil embolization. In the 18 patients in whom stenting was attempted, the overall success in reaching the target lesion was 94.4%. Of the 17 patients treated with stents, stent release and positioning were considered optimal in 16 (94%) and suboptimal in one (6%). In patients who underwent a successful procedure, all parent arteries were preserved. There were no instances of postprocedural ischemic attacks, new neurologic deficits, or new minor or major strokes prior to patient discharge. In follow up, all patients were assessed, using the modified Rankin scale, as functionally improved or of stable clinical status. The reduction in dissection-induced stenosis or pseudoaneurysm, the patency rate obtained at follow-up, and the lack of strokes (ischemic or hemorrhagic) suggest that stent placement offers a viable alternative to complex surgical bypass or reconstructive procedures. The long-term efficacy and durability of stent placement for arterial dissection remain to be determined in a larger series

    2006-08-15

    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.

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.

    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.

    Pediatric patients with dissecting aneurysms usually present with ischemia rather than bleeding. We report a case of a 15-year-old boy with a dissecting aneurysm of the posterior cerebral artery (PCA) presenting with hemorrhage. He was first treated with stent-assisted coil embolization, in an attempt to avoid trapping of the PCA and preserve the perforators. After the procedure, he recovered well from general anesthesia, but rebleeding occurred from the same lesion 6 hours after the procedur...

    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.

    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.

  12. Carotid artery dissection on non-contrast CT: Does color improve the diagnostic confidence?

    International Nuclear Information System (INIS)

    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 We report a case of multiple spontaneous arteries dissection in a 52-year-old female; the patient had a relevant family history of vascular complications and typical features so we hypothesized vascular Ehlers-Danlos syndrome (EDS that was confirmed by genetic analysis of COL3A1 gene. We adopted a conservative approach: the patient was treated with heparin in the acute phase followed by aspirin and then celiprolol was started on the basis of a recent trial that demonstrates a reduction in arterial events in EDS patient treated. A careful follow-up was done with Doppler ultrasound and computed tomography scan, as non-invasive diagnostic techniques are preferred in these patients, and no other vascular symptomatic events have occurred. We tested all living relatives: half of them had COL3A1 mutation, they were referred to another center specialized in rare diseases and EDS for long-term follow-up and genetic counseling. This case demonstrates as a careful evaluation of clinical signs, clinical history of the patient and his family has allowed a definitive diagnosis, proper management of the patient during the acute event and in terms of prophylaxis of recurrence.

    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.

    We report a case of multiple symptomatic cerebral infarctions from a traumatic vertebral artery dissection (VAD) after cervical fractures. A 73-year-old man was admitted with stuporous mentality and left hemiparesis after a motor-vehicle accident. A brain computed tomography (CT) scan at admission showed a traumatic subarachnoid hemorrhage on the left parietal lobe. A cervical CT scan showed left lateral mass fractures on C2, C5, and C6, involving the transverse foramen. Cervical spine magnetic resonance imaging (MRI) revealed loss of signal void on the left vertebral artery. Neck CT angiography showed left VAD starting at the C5 level. Brain MRI revealed acute, multiple cerebral infarctions involving the pons, midbrain, thalamus, corpus callosum, and parietal and frontal lobes on diffusion weighted images. The patient was treated conservatively at the intensive care unit in the acute stage to prevent extent of stroke. Aspirin was started for antiplatelet therapy in the chronic stage. The possibility of symptomatic cerebral infarctions due to traumatic VAD following cervical fracture should be considered. PMID:27182500

    After arising from the brachial artery in the cubital fossa the ulnar artery usually passes deep into the superficial flexor muscles of the forearm. In the lower two-thirds, it typically follows a sub-fascial course. In the present case, during a routine undergraduate course dissection of a cadaver, it was found that the ulnar artery arose normally as a terminal branch of the brachial artery in the cubital fossa, followed a sub-fascial course by lying superficial to the flexor muscles then completed the superficial palmar arch in hand. This artery gave only minute muscular branches in the forearm. Moreover, the main branches that usually arise from the ulnar artery were given off by the radial artery. This type of variation is of importance for both the clinicians and surgeons due to its vulnerability to injuries and of academic interest for anatomists. PMID:26715898

    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.

  3. Clinical features and treatment strategy in intracranial arterial dissection of ischemic onset

    International Nuclear Information System (INIS)

    The natural history of intracranial arterial dissection (ICAD) is not known precisely, so that treatment strategy is hard to determine in some cases. We examined the clinical features, treatment and long-term outcomes in the ICAD of ischemic onset. Among 214 consecutive patients with ICAD [199 in the vertebrobasilar system (VBs) and 15 in the internal carotid system (ICs)], 76 presented with brain ischemia. Those were classified into 2 groups: 53 in the VBs and 13 in the ICs. We analyzed age, site of dissection, progression or recurrence of ischemia, medical and surgical treatment, and long-term outcomes. The outcomes were evaluated by modified Rankin disability scale (mRS). Good outcome was defined as mRS 0 to 2. The patients were younger in the ICs (mean: 44.8 years) than in the VBs (mean: 53.0 years). The vertebral artery was mostly affected in both arterial systems. The acute stage progression or recurrence of ischemia was observed in 37% of the VBs and 54% of the ICs. The progression or recurrence is more frequent in the patients of the VBs with antithrombotic therapy (p=0.0224). Treatment: Medical treatment was performed in 94% of the VBs and in all of the ICs. In addition, antithrombotic agents were prescribed in 38% of the VBs and in 85% of the ICs. Four patients (6%) of the VBs were surgically treated because of enlargement of the aneurismal dilatation on follow-up study of MRI/MRA or 3D-CT angiography. Long-term outcomes: In the medical group, good outcomes were achieved in 77% of the VBs and all of the ICs. In the VBs, the patients with antithrombotic therapy had poorer outcomes than those without the therapy (P=0.0399). All the patients in the surgical group had good outcomes in the VBs. These results suggest that antithrombotic therapy might lead to the progression or recurrence of ICAD and a poorer outcome. This therapy should be selected prudently in the ICAD of ischemic onset, especially in the VBs. (author)

    The purpose was to evaluate CT findings of hemorrhage extending along the pulmonary artery (PA) due to ruptured aortic dissection (AD) and its prognostic factors. In 232 patients with Stanford type A AD, 21 patients (9.1%; 11 women; mean 70.3 years) were diagnosed. Twelve patients had double-barreled (classic) AD, and nine patients had intramural hematoma (IMH; closed false lumen) of the aorta. Based on CT findings, hemorrhage was classified into three categories as follows: category 1 (IMH of the PA or blood localized around the PA), category 2 (extending into the interlobular septa), and category 3 (extending into the alveoli). The factors influencing prognosis, including CT features and patient characteristics, were evaluated. Fourteen (66.7%) of the 21 patients underwent emergency surgery, and 8 (38.1%) patients died within 72 h of onset. Twelve cases (57.1%) were classified into category 1, 2 cases (9.5%) into category 2, and 7 cases (33.3%) into category 3. Double-barreled AD and category 3 hemorrhage were significant risk factors for death in univariate analyses. In multivariate analyses, the presence of category 3 hemorrhage was the only significant risk factor for death. CT findings indicative of a poor prognosis include double-barreled type AD and category 3 hemorrhage. (orig.)

    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.

    A 33-year-old woman with no premorbidities presented to us with chest pain and worsening dyspnoea since 1 week. Systemic examination was suggestive of acute pulmonary oedema and preliminary investigations revealed evolved anterior wall myocardial infarction (MI). The patient was stabilised and taken up for angiography which revealed spontaneous coronary artery dissection (SCAD) of the left anterior descending (LAD) artery. She underwent percutaneous coronary intervention (PCI) for the same. Further investigation into the cause for the SCAD came strongly positive for systemic lupus erythematosus (SLE). She had no prior symptoms suggestive of SLE and the SCAD was its very first clinical manifestation. PMID:27558190

  9. Clinically occult chronic dissecting aneurysm of the superior cerebellar artery in a child

    International Nuclear Information System (INIS)

    An isolated chronic dissecting aneurysm of the left superior cerebellar artery was discovered incidentally in a 12-year-old girl. There was no history of any previous trauma or witnessed abnormal neurological incident at any stage during her life. She was and has since remained asymptomatic and the aneurysm has remained radiologically stable for over 3 years. A conservative approach to the management of such incidental asymptomatic lesions is thus suggested. (orig.)

    Spontaneous cervical artery dissection (sCAD) is a major cause of ischemic stroke in young adults. Frequently, sCAD involves multiple neck arteries, accounting for 13%-28% of the total sCAD cases. However, little is known about factors related to multiple sCAD. In this case, a 52-year-old man was admitted due to headache without aura. There was a personal history of migraine with aura and a family history of similar symptoms. The patient's younger brother had a left vertebral artery (VA) dissecting aneurysm and underwent endovascular occlusion of his parent artery at the age of 48. Magnetic resonance imaging of our admitted patient showed hyperintensities in the right internal carotid artery (ICA) without acute infarction, and magnetic resonance angiography revealed a narrowing of the right ICA. Angiography was then performed, which showed a trace of dissection of the left ICA and both VAs as well as the right ICA. The patient did not fulfill any major criteria of collagen vascular disease such as Ehlers-Danlos syndrome type IV or Loeys-Dietz syndrome. The data in our patient are quite similar to those reported in patients with single-nucleotide polymorphism (SNP) of PHACTR1. Obtaining the patient's informed consent, we analyzed a common SNP variation in the rs9349379[G] allele (PHACTR1), which has been reported to be associated with a lower risk of sCAD. PMID:27216377

    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. PMID:21546166

    The cases of 3 patients with brain malperfusion secondary to acute aortic dissection who underwent preoperative perfusion of the right common carotid artery are presented. The patients were 64, 65 and 72 years old and 2 were female. All were in a comatose or semi-comatose state with left hemiplegia. The right common carotid artery was exposed and directly cannulated, using a 12-Fr paediatric arterial cannula. The right common femoral artery was chosen for arterial drainage, using a 14-Fr double-lumen cannula. The circuit contained a small roller pump and heat exchanger coil. Target flow was set at 90 ml/min and blood temperature at 30 °C. Durations of right carotid perfusion were 120, 100 and 45 min, respectively. All underwent partial arch replacement and survived. Postoperative neurological sequelae were minimal in all cases. PMID:26003959

    Spontaneous coronary artery dissection (SCAD) is an infrequent event that is most commonly associated with pregnant women or those in the postpartum period. Because of its rarity, the literature describing this condition is confined to sporadic case reports, with few reporting long-term follow-up, and no clear consensus exists on the optimal treatment strategy for these patients. The present article reports a single-centre experience with SCAD, highlighting the issues surrounding its management with a brief description of five cases of pregnancy-associated coronary dissection. The treatment used in these cases ranged from a conservative medical approach to surgical and percutaneous intervention, with one patient proceeding to transplantation. Four of the cases have long-term angiographic follow-up. In addition, a comprehensive review of all previously published cases is presented, and temporal trends in the management strategy are highlighted. Possible pathophysiological mechanisms pertaining to this condition, and the complex diagnostic and therapeutic issues involved, which may affect both patient and fetus, are discussed. Finally, an optimal approach to patients with SCAD, informed by our experience and literature review, is described. PMID:19492033

    Full Text Available Superficial brachial artery is one of the major variations of the arterial pattern in the upper limb. During routine anatomical dissection in our department, we observed a case of unilateral double brachial artery in a formalin-fixed female cadaver.Left axillary artery entered into the anterior region of the arm, where it branched into two brachial arteries – the superficial brachial artery (SBA, which was longer, tortuous and with a smaller caliber, and the brachial artery (BA, which was placed deep and medially. In the cubital fossa, covered with an aponeurosis of the biceps brachii muscle, both brachial arteries were connected with an anastomotic vessel. Under this anastomotic branch, in the forearm, SBA continued as the radial artery, whereas BA continued as the ulnar artery.Variations of the arterial pattern in the upper limb are undoubtedly of interest to the anatomists as well as to the clinicians.

    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.

    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.

    Treatment of a dissecting aneurysm of the medullary segments of the posterior inferior cerebellar artery (PICA) usually entails trapping of the diseased arterial segment with possible sacrifice of brainstem perforators. The goal of the work was to review our experience with selective coiling of ruptured, dissecting aneurysms of the anterolateral segments of the PICA without parent vessel occlusion. Eleven consecutive patients (9 women, 2 men, mean age 47.2 years) were retrospectively reviewed from a prospectively acquired neuroradiological database. On admission three patients had Hunt and Hess (HH) grade I, three HH grade II, two HH grade III, and one HH grade IV. Outcome was evaluated according to the modified Rankin scale (mRS) score. Follow-up (mean:19.4 months) consisted of magnetic resonance angiography and/or digital subtraction angiography in ten patients. Ten patients had mRS score 0 and one mRS score 2. No treatment failure occurred. The aneurysm was completely occluded in seven patients, a neck residue was present in two, and a loose coil mesh was present in two. Recurrence occurred in three patients, and all were successfully retreated for a total of 13 procedures. Procedure-related complications were all without clinical consequences and included a coil perforation in one procedure and stagnant filling of the parent vessel in six procedures. PICA occlusion did not occur in any patient. Coiling of ruptured, isolated dissecting aneurysms of the PICA without parent vessel occlusion is feasible, relatively safe and effective in preventing early/medium-term rebleeding. A strict angiographic follow-up program is, however, necessary to detect recurrence. (orig.)

    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.

    Three kinds of carotid-basilar anastomosis have been found, they were named as persistent primitive trigeminal artery, persistent primitive acoustic (or otic) artery and persistent primitive hypoglossal artery, among them, the persistent primitive hypoglossal artery is by far the least common type of the internal carotid-basilar anastomosis which have been demonstrate in human postembryonic stages. Persistent primitive by hypoglossal artery is usually found incidentally. This vascular anomaly, however,have been reported to be associated with multiple congenital anomalies, such as unilateral or bilateral vertebral artery hypoplasia, absence of the posterior communicating artery, hypoplasia of the proximal portion of the posterior cerebral artery, aneurysm of the circle of Willis, the origin of both pericallosal arteries from a single anterior cerebral artery, retarded mental development dating from infancy, carotid-cavernous fistula formation etc. A case of persistent primitive hypoglossal artery in an young Korean male was reported with brief review of the literature.

    We report a case of successful laparoscopic distal gastrectomy with D2 lymph node dissection preserving the common hepatic artery branched from the left gastric artery for advanced gastric cancer with an Adachi type VI (group 26) vascular anomaly. A 76-year-old female patient was admitted with a diagnosis of advanced gastric cancer at the anterior wall to the lesser curvature of the antrum (cT3N0M0 cStage IIA). Dynamic computed tomography showed the ectopia of the common hepatic artery branched from the left gastric artery. We made a diagnosis of an Adachi type VI (group 26) vascular anomaly and performed the abovementioned operation. In this anomaly pattern, scrupulous attention is required to remove the suprapancreatic lymph nodes because the portal vein is located immediately dorsal to those lymph nodes and is at increased risk for the injury in this situation. The common hepatic artery is branched from the left gastric artery, and the hepatic perfusion from the superior mesenteric artery is not present in group 26. Planning to preserve the artery will improve safety when it is possible oncologically. There were no postoperative complications, and the patient was discharged 9 days after the operation. To our knowledge, the present case is the first reported case of a laparoscopic distal gastrectomy with D2 lymph node dissection with an Adachi type VI (group 26) vascular anomaly. Preoperative diagnostic imaging is very important to prevent surgical complications because the reliable identification of vascular anomaly during an operation is very difficult. PMID:27259578

    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.

    This report describes a rare case of an arterial anomaly in the celiaco-mesenteric region, encountered in a Japanese female cadaver for dissection at the gross anatomy laboratory of Kurume University School of Medicine in 2003. The usual celiac trunk was not identified, and the left gastric artery, the splenic artery and the hepato-mesenteric trunk independently arose from the abdominal aorta. Moreover, the hepatic artery arising from the hepato-mesenteric trunk ran behind the portal vein. The classification for this type of arterial anomaly is a Type II' of Morita's classification and Type II of Higashi and Hirai's classification, not belong to the Adachi's. PMID:16119612

    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. PMID:27651873

    Aim: To present our experience of the clinical management of spontaneous isolated dissection of superior mesenteric artery (SIDSMA) and analyse the clinical features, imaging findings, and treatment outcomes. Materials and methods: In this retrospective study, eight consecutive patients with symptomatic SIDSMA were treated in Chang Gung Memorial Hospital between April 2007 and April 2010; among these patients, six underwent endovascular stent placement. The clinical manifestations, imaging findings, endovascular stent placement outcome, and follow-up results of the patients were retrospectively analysed. Results: Eight patients were diagnosed with SIDSMA by contrast-enhanced computer tomography. One patient died due to comorbidity before angiography. Six patients underwent percutaneous endovascular stent placement in the superior mesenteric artery (SMA): four patients with bare stents and two with stent grafts. Because it was not appropriate to perform stent implantation in the remaining patient, he received only conservative treatment. All seven patients had an uneventful recovery and the follow-up period was 16 month, ranging from 1 to 35 months. Conclusion: For patients with symptomatic SIDSMA, endovascular repair is a feasible treatment choice with a high success rate and good clinical outcome.

    We report a case of subarachnoid hemorrhage(SAH)from an intracranial vertebral artery(VA)dissection in a patient with fibromuscular dysplasia(FMD)who presented with headache. A 54-year-old woman complained of spontaneous occipital headache. The dilatation of the left VA was detected on magnetic resonance angiography(MRA). She was diagnosed with left VA dissection(headache onset type). After sudden onset of headache on the second day of hospitalization, her consciousness level, as defined by the Japan Coma Scale, was 300. Computed tomography(CT)revealed SAH. Cerebral angiography showed the dilatation of the left intracranial VA and contrast material pooling, which was suspected to be a sign of dissection. We performed VA intravascular ligation by coil embolization. The postoperative course was good but postoperative MRA revealed arterial wall irregularities in both the extra cranial internal carotid artery and the right VA. Cerebral angiography showed the presence of the string-of-beads sign at these arteries. She was diagnosed with FMD. SAH might develop during the follow-up period in patients with VA dissection, even those in whom the initial symptom is headache. In addition, cases of FMD might also be complicated by various lesions of the main trunk of the cerebral artery. PMID:27384119

    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

    We describe the case of a 79-year-old male presented with sudden onset of abdominal pain and mild breathlessness, and complicated acute progressive anemia with haemoglobin which declined from 120 g/L to 70 g/L within five days. An urgent computed tomography an-giography showed acute thoracic aortic dissection, DeBakey type IIIb, a dissecting aneurysm in the proximal descending thoracic aorta start-ing immediately after the origin of the left subclavian artery and extending distally below the renal arteries with evidence of rupture into the right pleural cavity for massive pleural effusion. Plasma D-dimer, brain natriuretic peptide and C reactive protein level were elevated. Our case showed that D-dimer can be used as a‘rule-out’ test in patients with suspected aortic dissection. A raised BNP may exert a protective role through anti-inflammatory endothelial actions in the systemic circulation.

    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.

    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.

  20. The location of origin of spontaneous extracranial internal carotid artery dissection is adjacent to the skull base

    International Nuclear Information System (INIS)

    The traditional view is that spontaneous extracranial internal carotid artery (ICA) dissection (CAD) extends cranially from an intimal tear located just beyond the carotid bulb. This paper demonstrates that CAD originates in and primarily involves a more distal segment of the artery. A retrospective study of 54 dissected ICAs in 50 consecutive patients with spontaneous or traumatic CAD was undertaken. The site of the dissection, presence of ICA redundancy, rate of acute or delayed ischaemic stroke and vessel remodelling were determined. Of the 51 dissections that occurred spontaneously or after indirect trauma, 25/51 (49.0%) were solely in the distal third of the artery, and 49/51 (96.1%) involved the distal two-thirds. Only 2/51 (3.9%) originated in the proximal third. ICA redundancy was seen in 27/36 (75%) of patients with spontaneous CAD, compared with only 1/11 (9.1%) of those with CAD due to indirect trauma (P = 0.0002). Acute stroke occurred in 10/12 (83.3%) of patients with ICA occlusion secondary to CAD and in 14/38 (36.8%) with non-occlusive CAD (P = 0.0074). Where follow-up was available, only 2/32 (6.3%) patients had a stroke after diagnosis, and 19/33 (57.6%) ICAs recanalised or remodelled. CAD occurring spontaneously or due to indirect trauma most frequently involves the distal extracranial ICA. Spontaneous CAD is associated with vessel redundancy, and the risk of acute stroke is greatest with occlusive CAD. The prognosis is good with treatment, with a low rate of recurrent stroke and a high rate of vessel remodelling.

    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

    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.

    dissection were followed up with DSA examination. Results Of the 1 311, iatrogenic hepatic artery dissection occurred in 12 (0.92%). All the iatrogenic hepatic artery dissections were caused by improper manipulation. The locations of the hepatic artery dissection included proper hepatic artery (n - 8), right hepatic artery (n = 3) and common hepatic artery (n = 1). All the artery dissections were situated at the turning point of the involved arteries. Of the 12 cases, 3 F micro-catheter was employed in 10, and 0.035-inch guide-wire was used in one case, which was successfully manipulated into the targeted hepatic artery through the true arterial cavity and TACE was then accomplished. In the remaining one case the catheterization failed after repeated try in an attempt to pass through the true arterial cavity, and, finally, transcatheter hepatic arterial infusion chemotherapy had to be adopted. All the patients were followed up for 3 - 15 months, and the median follow-up time was 8 months. Of the 10 patients who received subsequent endovascular intervention therapy, hepatic angiography showed that no arterial dissection was found in 2 and different degree of the reduction of the false lumen was seen in 8. Conclusion The occurrence of hepatic artery dissection that occurs during the performance of TACE for hepatic malignancies is closely related to the operator's manipulation skill and the running course of the hepatic artery. Usually, TACE can be successfully performed by manipulating micro-catheter and micro-guidewire passing through the true lumen of the segment of dissection. The main bad consequence of the presence of the hepatic arterial dissection is that it can cause the TACE procedure to become difficult, and as a result the clinical efficacy and the patient's prognosis are affected. Therefore, more attention should be paid to its prevention and management.

    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.

    Idiopathic arterial calcification of infancy is a rare autosomal recessive disease, characterized by deposition of calcium along the internal elastic membrane of arteries, accompanied by fibrous thickening of the intima which causes luminal narrowing. Here we are reporting a case of idiopathic arterial calcification of infancy in a Saudi female newborn of non-consanguineous pregnant woman who had polyhydramnios. The newborn baby had severe respiratory distress, systemic hypertension and persistent pulmonary hypertension of newborn. She was admitted to Neonatal Intensive Care Unit, where she was ventilated and proper treatment was provided. Molecular genetic testing was positive for mutations of ectonucleotide pyrophosphatase/phosphodiesterase1 gene which is reported in 80% of cases of Idiopathic arterial calcification of infancy. The baby died at about 5 month of age because of myocardial ischemia and cardiorespiratory arrest. Idiopathic Arterial Calcification of Infancy should be considered in any newborn who presented with persistent pulmonary hypertension of newborn, severe systemic hypertension and echogenic vessels on any radiological study. Calcifications of large and medium-sized arteries are important diagnostic finding. PMID:27252793

    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.

    A 22-year-old woman presented to the emergency department (ED) after suffering injuries as a restrained driver in a head-on motor vehicle accident. Upon presentation to the ED, her Glasgow Coma Score (GCS) was 15. A computed tomography (CT) of the head and neck was negative. She was taken to surgery for orthopedic injuries. Recovery from general anesthesia was somewhat prolonged due to somnolence. Roughly two hours after transfer, her family noticed that she was not moving her left arm. Trauma staff noted she had a new left hemiparesis. She was promptly taken for a repeat head CT which showed a dense area of ischemia in her right cerebral hemisphere, in the distribution of the right middle cerebral artery (MCA). A CT angiogram of the head and neck revealed a large dissection of the right carotid artery below the level of C2-C3, complete occlusion of the right internal carotid artery beginning 2 cm superior to the bifurcation, and developing cerebral edema with subsequent leftward shift.

    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 Introduction. Although the third most common aneurysm within the abdomen, after aneurysms of the aorta and iliac arteries, splenic artery aneurysms are rare, but not exceptionally. Owing to new imaging techniques, they have been discovered with increasing frequency. Case Outline. Authors present a 47-year-old woman, multipara, who presented with left upper abdominal pain in whom X-ray showed a calcified ring in the area of distal pancreas. Selective angiography confirmed a splenic artery aneurysm of its proximal part. During an open surgery the aneurysm was excised (aneurismectomy without immediate, early or late complications. The patient became symptom-free. Conclusion. In patients, particularly women, the multiparas who present with epigastric or left upper abdominal pain of unknown aetiology, splenic artery aneurysm has to be taken into account. Further diagnostic procedures such as plain X-ray and selective angiography in suspected cases should be performed. Surgery or other treatment modalities are to be seriously considered in all patients, particularly in those with increased risk of rupture.

    We report the case of a 19-year-old man with a history of Loeys-Dietz syndrome (LDS), which was diagnosed when he had a Stanford type A aortic dissection. He also had multiple aneurysms including ones in the innominate, right common carotid, and right internal mammary arteries. He had had multiple procedures including Bentall's procedure, repeat sternotomy with complete arch and valve replacement, and coil embolization of internal mammary artery aneurysm in the past. His LDS was characterized by gene mutation for transforming growth factor-β receptor 1. He presented to our facility with sudden onset of back pain, radiating to the right shoulder and chest. He was diagnosed with Stanford type B aortic dissection and underwent thoracic aorta endovascular repair for his aortic dissection. This case represents the broad spectrum of pathology associated with LDS where even with regular surveillance and aggressive medical management the patient developed Stanford B aortic dissection.

    Although occipital artery (OA)-to-posterior inferior cerebellar artery (PICA) anastomosis is the most familiar reconstruction for posterior cerebral circulation, the procedure is considered difficult because of the anatomical complex course of OA and the depth of the operative field at the anastomosis site. Therefore, we attempted a safe and reliable method for OA-to-PICA anastomosis under multiple-layer dissection of suboccipital muscles and a reverse C-shaped skin incision. We reviewed the clinical records of patients who underwent OA-to-PICA anastomosis in our institute, and report the outcome with special emphasis on graft patency and surgical complications. Nine patients are described. In one patient the bypass was accomplished at the cortical segment of the PICA and in all others at the caudal loop. The average time for de-clamping the PICA was 29 min and 29 s. Although the overall graft patency rate was 100%, one patient showed a new medulla infarction at the time of post-operatory three-dimensional computed tomography angiography. Besides a secure OA-to-PICA anastomosis, this technique allows safe harvest of the OA and the creation of a shallow and wide anastomosis field. PMID:25633907

    This report describes 2 cases of spontaneous aortic dissecting hematoma in young Border Collie and Border Collie crossbred dogs. Histology was performed in one of the cases involving an unusual splitting of the elastin present within the wall of the aorta, consistent with elastin dysplasia as described in Marfan syndrome in humans. The first case involved a young purebred Border Collie that died suddenly and the second case involved a Border Collie crossbred dog that died after a 1-month history of seizures. Gross lesions included pericardial tamponade with dissection of the ascending aorta in the former case and thoracic cavity hemorrhage, mediastinal hematoma, and aortic dissection in the latter. Histologic lesions in the case of the Border Collie crossbred dog included a dissecting hematoma of the ascending aorta with elastin dysplasia and right axillary arterial intimal proliferation.

    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.

    The aim of this study was to determine the clinical outcomes of long-term anticoagulation therapy in patients with symptomatic spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) and to evaluate whether conservative treatment with anticoagulation therapy is a safe and effective treatment modality for these patients.In this single center, observational cohort study, data from a prospectively recruiting symptomatic SIDSMA registry, including demographics, risk factors of interest, clinical characteristics and outcomes, and initial and follow-up computed tomography angiography (CTA) findings, were analyzed retrospectively.During an 8-year period, a total of 52 consecutive patients who underwent conservative treatment with the use of long-term anticoagulation were included in this study. Clinical symptoms resolved within 11 days in all except 4 patients (7.7%); 3 received endovascular treatment for persistent symptoms and 1 received surgical repair. The mean duration of anticoagulation therapy was 9 (range: 3-60) months. A follow-up CTA showed complete remodeling in 20 (41.7%) patients, and the mean diameter and the incidence of false lumen thrombosis were also decreased significantly. There was no anticoagulation therapy-related mortality or morbidity except 2 (4.2%) minor bleeding complications, and no symptomatic recurrence or aggravation of the dissection occurred during the mean follow-up period of 47.5 (range: 10-97) months.The present study showed that long-term anticoagulation therapy could result in a high rate of complete remodeling during the natural course of symptomatic SIDSMA. Conservative treatment with long-term anticoagulation therapy could be an optimal treatment strategy for symptomatic SIDSMA. PMID:27100453

  5. A case of William's syndrome associated peripheral pulmonary arterial stenosis

    International Nuclear Information System (INIS)

    William's syndrome, in order to more completely delineate the total spectrum of the disorder, indicates that 'infantile hypercalcemia', 'peculiar facies' and 'supravalvular aortic stenosis.' In has other many vascular anomalies, such as peripheral pulmonary arterial stenosis, coronary arterial stenosis, celiac arterial stenosis, and renal aterial stenosis. Only 32% of the patients have evidence of supravalvular aortic stenosis. And it is very rare disease entity that has been reported rarely in Korea. Recently authors experienced a case that was questioned William's syndrome with peripheral pulmonary arterial stenosis, clinically and preliminary radiologically and this case was confirmed by operation. Here we report a case of William's syndrome with peripheral pulmonary arterial stenosis and reviewed literatures

    2014-01-01

    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.

    Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) is a widely accepted and well established procedure because of its curative potential and low invasiveness compared with surgery. Perforation is a potential major complication during ESD, and non-surgical treatments such as endoscopic closure with clips are sufficient in most cases. Here, we report a case of perigastric abscess that occurred as a complication of ESD for EGC. The patient improved with administration of antibiotics without surgical intervention. PMID:26996184

    the other 2; acute aortic dissection was diagnosed in 89 of the patients and chronic aortic dissection in the other 9. Thoracic endovascular aortic repair (TEVAR) was done in 83 patients, surgical repair in one patient, and conservative treatment was carried out in the other 10 patients. Four patients died of ruptured aortic aneurysm before operation. In the rest of the patients, we used tubular membrane-covered stent in 80 patients, and branched membrane-covered stent in 3; hybrid operation was performed on 7 patients including axillo-axillary arterial bypass in 5 patients, and left carotid-subclavian arterial bypass in 2 before endovascular treatment. In the 10 patients who received conservative treatment, 4 recovered in one week. Nine patients with chronic aortic dissection underwent endovascular repair for progressively expanded false lumen. Results Perioperative death occurred in 2 patients who received TEVAR(2. 4% ) :one patient died of pericardial tamponade ( confirmed by autopsy) one week after the endovascular repair, and the other patient died on the second postoperative day with an unidentified cause which was supposed to be a new tear in the aortic wall. Other 81 patients who received TEVAR recovered uneventfully. Type I endoleak was found in 14 of the patients (16. 9% ) ; thrombosis in the false lumen was found in 69 patients on discharge, whereas partial blood flow was still present in the false lumen in 12 patients. Six out of the 10 cases of conservative treatment had thrombosis in the false lumen. Totally 84 patients,including 75 patients who underwent endovascular repair, 8 patients who received conserving treatments,and 1 patient who had surgical repair,were followed up (91. 3% ) for 2-121 months (mean, 36. 5 months). One patient died 3 months after the endovascular repair due to rupture of the descending thoracic aorta.

    A 54-year-old man who suffered from paraplegia due to type B aortic dissection was treated with a Valiant stent-graft. However, attempts to gain secure proximal sealing resulted in an inadvertent coverage of the left common carotid artery by the endograft. The blood flow in the left common carotid artery was restored by a transcarotid Smart Control stent in a chimney fashion. At 6- and 18-month follow-up, computed tomography scan showed that the chimney stent was severely compressed by the stent graft, although the patient remained neurologically asymptomatic.

    2012-11-01

    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.

    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.

    Case Presentation. We report the case of a 66-year-old Caucasian male who presented a syncope immediately followed by a left-arm weakness while driving his car. Clinical examination was normal, but bilateral jugular vein distension was noted. Electrocardiogram and chest radiography were unremarkable. Among blood tests performed, troponin I test result was negative, and D-dimer test concentration was >4000 ng/mL. Since D-dimer test result was positive, chest computer tomography angiogram was performed and found a thoracic aortic dissection. Conclusion. Our case report shows that acute aortic dissection diagnosis is difficult and must be associated with the interpretation of various clinical signs and D-dimer measurement. It could be helpful for the emergency physician to have a pretest probability D-dimer like in pulmonary embolism diagnosis.

    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.

    This case report concerns a 62-year-old woman with spontaneous infrarenal abdominal aortic dissection, which developed into claudication and rest pain in the lower extremity. Multi-row detector computed tomography showed the entry site of the abdominal aortic dissection at the second lumbar artery, while the reentry site was found intraoperatively at the median sacral artery, indicating that the false lumen had progressed and compressed the true lumen. A direct approach involving grafting appears to be an effective procedure for resolving mesenteric and lower extremity hypoperfusion due to aortic dissection with a dilated false channel, even during the acute period.

    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.

    2014-05-01

    Full Text Available Variations in the origin of arteries in the abdomen are very common. With the invention of new operative techniques within the abdomen cavity, the anatomy of abdominal vessels has assumed a great deal of clinical importance. We report here a rare case of formation of an "arterial glomerulus" at the hilum of the right kidney by the branches of right renal artery. There were 2 renal veins; a superficial and a deep. The deep vein had a peculiar course through the arterial glomerulus. The right testicular vein drained into the deep renal vein. We also observed a variant origin and course of right testicular artery. Prior knowledge of unusual branching pattern of renal vessels is necessary in the surgical interventions which require hilar dissection. Similarly, abnormal origin or course of testicular artery becomes apparent during surgical procedures like varicocele and undescended testes. Therefore, knowledge of such an anomaly in the testicular artery helps to avoid iatrogenic injuries during radiological or surgical procedures.

    The trigeminal artery is an anastomosis between the embryonic precursors of the vertebrobasilar and carotid systems, and may persist into adult life. The association of the persistent primitive trigeminal artery (PTA) with cerebral aneurysm is well documented in the literature and, in general, aneurysms are located in the anterior circulation. We describe a patient who presented with a panencephalic Fisher III subarachnoid hemorrhage due to rupture of an intracranial aneurysm. Digital arteriography showed a saccular aneurysm in the middle third of the basilar artery, adjacent to the junction with a persistent trigeminal artery. She was submitted to endovascular treatment with embolization of the basilar artery aneurysm with coils. Aneurysms at the PTA junction with the basilar artery are rare. This paper describes a case of PTA associated with an aneurysm in the basilar artery at PTA junction and briefly reviews the literature. PMID:22005697

    2015-01-01

    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 Fasciculations are symptoms present in a broad spectrum of conditions, ranging from normal manifestations to motor neuron diseases. They also represent the main picture of benign fasciculation syndrome. We report a case of such syndrome: a 48-years-old woman complaining about fasciculations for three decades who remained with the symptoms even after the compensation of a disclosed hyperthyroidism. The introduction of gabapentin rendered control of her fasciculations. The available data in the literature about the therapeutic approaches for fasciculations are revised, as long as the rare reports of evolution from patients with "benign" fasciculations to cases of amyotrophic lateral sclerosis, underlining the importance of following the patients with fasciculations.Fasciculações são sintomas presentes em um amplo espectro de condições, desde manifestações normais até doenças do neurônio motor. Elas representam também o principal aspecto da síndrome de fasciculações benignas. Relatamos um caso desta síndrome: uma paciente de 48 anos com queixas de fasciculações por três décadas que, mesmo após a compensação de um quadro de hipertireoidismo, permaneceu com os sintomas.

    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.

    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.

    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.

  9. A Case of Incomplete Central Retinal Artery Occlusion Associated with Short Posterior Ciliary Artery Occlusion

    Full Text Available To our knowledge, incomplete central retinal artery occlusion associated with short posterior ciliary artery occlusion is extremely rare. Herein, we describe a case of a 62-year-old man who was referred to our hospital with of transient blindness in his right eye. At initial examination, the patient’s best-corrected visual acuity was 18/20 in the right eye. Fundus examination showed multiple soft exudates around the optic disc and mild macular retinal edema in his right eye; however, a cherry red spot on the macula was not detected. Fluorescein angiography revealed delayed dye inflow into the nasal choroidal hemisphere that is supplied by the short posterior ciliary artery. The following day, the patient’s visual acuity improved to 20/20. Soft exudates around the optic disc increased during observation and gradually disappeared. His hemodynamic parameters revealed subclavian steal syndrome as examined by cervical ultrasonography and digital subtraction angiography. We speculate that his transient blindness was due to ophthalmic artery spasms. In this particular case, spasms of the ophthalmic artery and occlusion of the short posterior ciliary artery occurred simultaneously. As the short posterior ciliary artery branches from the ophthalmic artery, the anatomical location of the lesion might be near the branching of both arteries.

    Spontaneous dissection of the internal carotid artery (CAD) is an increasingly recognized cause for stroke especially in young and middle-aged patients. We hypothesized that non-enhanced cranial computed tomography (NECCT) can visualize the subpetrous carotid wall hematoma and thus enable identification of patients with CAD. We retrospectively reviewed patients with confirmed CAD (n=21) and a control group with ischemic symptoms but without CAD (n=42) who received NECCT at admission. Two independent neuroradiologists rated the presence and shape of SPH, density and diameter of the subpetrous internal carotid artery. Additionally, we correlated the shape of the subpetrous carotid wall hematoma with the grade of stenosis on subsequent angiographic imaging. The subpetrous carotid wall hematoma was present in 14 of 21 patients (Cohen's k = 0.67). Mean diameter was 6.95 ± 1.05 mm in dissected vessels and 5.71 ± 1.52 mm in the contralateral vessel (p<0.05). Mean difference in vessel density was 15.05 ± 8.01 HU (p<0.01). Median grade of stenosis was significantly higher in patients with a full moon- shaped (n=11) than crescent-shaped (n=3) subpetrous carotid wall hematoma (21% vs. 80%, p<0.05). Two-thirds of patients with CAD were correctly identified on NECCT. The extracranial carotid artery should be evaluated in patients with symptoms of cerebral ischemia.

    Full Text Available A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy. Missed injuries in trauma patients are well-described phenomena and implementation of the ATLS® trauma schedule led to a decrease in the number of missed injuries, but trauma computed tomography (CT scans in injured patients are still not standard. We report on a 54-year old Caucasian female patient who was involved in a car accident. The fellow passenger of the car was seriously injured. The patient had been previously treated at two different hospitals, and a dislocated acetabular fracture had been diagnosed. Because of this injury, the patient was transferred to our institution, a level 1 trauma-center where, according to the nature of the accident as a high-energy trauma, a complete polytrauma management was performed at the time of admission. During the body check, a moderate tension of the lower parts of the abdomen was detected. During the CT scan, an aneurysm of the infra-renal aorta with a dissection from the height of the second lumbar vertebral body to the iliac artery was observed. The patient required an operation on the day of admission. After 19 days post-trauma care the patient was able to leave our hospital in good general condition. Therefore, missed injuries in multiple injury patients could be fatal, and it is essential that the orthopedic surgeon leaves room for suspicion of injuries based on the nature of the trauma. Traumatic injuries of the abdominal aorta are rare. According to the ATLS® trauma schedule, all of the patients who have experienced high-energy trauma and associated fractures should undergo routine screening using a trauma CT scan with contrast agents to detect

    Popliteal artery entrampment is a rare condition, occurring in young subjects, that causes ischemia of the extremity. The anatomical background is the compression or occlussion of the popliteal artery caused by forced plantar or dorsal flexion. We report a 32 year-old sportsman who presented with gangrene of the right first toe and a history of three months of progressive claudication. The Ankle-Brachial index and pulse volume curve registries showed a severe ischemia below the knee. Angiography showed a medial deviation of the popliteal artery associated to stenosis and aneurysm formation. A CT scan of the contralateral artery was normal. The patient was operated using a posterior approach, performing a reverse saphenous vein bypass graft and excising the popliteal artery. The postoperative period was uneventful. PMID:16554929

    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

    The radiologic manifestations of ruptured acute aortic dissection, Stanford type A aortic dissection, DeBakey type 1 can present in different radiographic scenarios with devastating outcomes. Here, we present a rare case of a 70-year-old man who presented to the emergency department with chest pain radiating to the back. A chest computed tomography scan showed a Stanford type A, DeBakey type 1, acute aortic dissection ruptured into the aortopulmonary window and stenosing the pulmonary trunk, both main pulmonary arteries, and dissecting the bronchovascular sheaths and flow into the pulmonary interstitium, causing pulmonary interstitial hemorrhage. The patient underwent emergent ascending aorta replacement with hemiarch replacement with circulatory arrest. The postoperative course was unremarkable. PMID:26140779

    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.

    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.

    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.

    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.

    2016-01-01

    In giant cell arteritis (GCA), involvement of the vertebral arteries is rare with reported rates of 3%–4% for ischemic events secondary to vertebral artery stenosis or occlusion for those patients with GCA. This case study describes a patient who initially presented with acute onset of vertigo but was also found to have transient, side-alternating upper limb neurological findings. While initial imaging showed no vascular abnormalities, it was not until GCA was eventually confirmed with a temporal artery biopsy that the initial scans were shown to have bilateral narrowing of the vertebral arteries. While rare, vertebral artery involvement is an important complication to consider in the setting of GCA due to the high rate of associated mortality, despite immunosuppressive therapy. PMID:27279753

    Dysplasia of the renal and cervical arteries are well known, but dysplasia of the superior mesenteric artery (SMA) is less frequent and has specific presentation. There have been few reports on the different types of presentations. We report a series of 38 cases and present the characteristic features together with a comparison with data in the literature. These non-atheromatous non-inflammatory lesions of the arterial wall occurred either in a context of fibromuscular disease which cause is unknown (30/38 patients) or in patients with genetic disease such as neurofibromatosis (3/38) or Ehlers-Danlos disease (5/38). The fibromuscular disease presented three aspects with specific characteristics. a) stenosing lesions found predominantly in women with a different morphology than in the other localization (usually associated): irregular diffuse stenosis discovered in patients with hypertension, or ischemic digestive symptoms (6/14 patients). b) Aneurysms, also found predominantly in women, but less frequently associated with other dysplasias. These aneurysms were generally sacciform. Unlike data in the literature, our series only included rupture in 1/8 cases. The aneurysm was discovered during the exploration of abdominal pain or hypertension. c) The third type of fibromuscular disease concerned dissections which were observed in the male population, (except one case of segmental dysplasia), and presented with signs of digestive ischemia in the other seven patients, four in an emergency context requiring immediate treatment. Two genetic diseases were observed. a) Neurofibromatosis led to dysplasia analogous to fibromuscular disease, but with abnormal nerve formations in the wall. For the three cases observed, one involved only the visceral arteries and the two others thoraco-abdominal coarctation. b) We had five patients with Ehlers-Danlos syndrome, with dysplasia of the superior mesenteric artery. For three there was a fusiform dilatation and in one small aneurysms

    We present a rare case of an aberrant right vertebral artery originated from the distal aortic arch. This issue has been incidentally detected on a preoperative CT angiography after a stabbing injury of the cervical spinal cord. Normally, the right vertebral artery originates from the right subclavian artery. Therefore, in this case report we will review the incidence and the embryological mechanism of this aberrant course of the right vertebral artery and we will discuss as well the clinical importance of this variation.

    2014-01-01

    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 Introduction & Background: True aneurysms of extra cranial vertebral arteries are rare. The usual pathogenesis of aneurysms in this location is either penetrating or blunt trauma with resultant pseudo- aneurysm formation. We report a patient with a presumed pseudo-aneurysm of the extra- cranial vertebral artery presenting with painful neck mass, without obvious history of trauma. Case description: A 59-year old man presented with painful left lateral neck mass from 3 month ago with a bruit over it on physical examination. Patient had a history of long term anticoagulant therapy because of chronic lower extremity DVT. Patient was referred to our DSA (Department for angiography. After color Doppler US, CT scan and MR-angiography were performed and a giant aneurysm in left vertebral artery was detected. The lesion was successfully treated by an endovascular technique of balloon occlusion of the verte-bral artery.

  20. Recurrent giant hypogastric artery aneurysms--a case report.

    1988-07-01

    Aneurysms of the hypogastric artery are rare occurrences that are frequently asymptomatic until the time of rupture. When signs and symptoms are present, a pulsatile pelvic mass, frequently detected by rectal or vaginal examination, may produce compression symptoms with urologic, gastrointestinal, and neurologic manifestations. In addition to classical invasive methods of detection such as angiography, newer noninvasive imaging techniques, including ultrasonography, computerized tomography, and magnetic resonance imaging, may be employed to establish the diagnosis. Proximal ligation of the hypogastric artery is the usual method of treatment. A case of bilateral, giant hypogastric artery aneurysms with successful surgical management is reported. PMID:3044197

    A 70-year-old female underwent an emergency replacement of the ascending aorta for acute aortic dissection. We used surgical adhesive BioGlue and teflon felt strips to reinforce the dissected aortic wall. On the 5th post operative day, electrocardiogram showed ischemic inverted T wave and the serum creatine phosphokinase level elevated without any symptoms such as chest pain or low blood pressure. By coronary angiography, severe stenosis was detected of the left descending coronary artery, and percutaneous coronary intervention was performed. Intravascular ultrasound images revealed that no atherosclerotic components were present in the embolic materials. As a result of in vitro examination, that material was probably a fragment of the BioGlue. The patient was discharged on foot 23 days after surgery. PMID:27365070

    2015-12-01

    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.

    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.

  5. Progressed Multivessel Spontaneous Coronary Artery Dissection That Naturally Healed in a Male Patient with Non-ST Segment Elevation Myocardial Infarction

    2016-01-01

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare condition that may have a serious outcome because of acute coronary syndrome. The condition especially affects young women. We evaluated a middle-aged male patient with a non-ST segment elevation myocardial infarction caused by multivessel SCAD. The SCAD had occurred in the distal right coronary artery (RCA, the mid left anterior descending artery (LAD, and the distal LAD at the same time. His culprit lesion was in the distal RCA, but the SCAD had progressed more proximally within the RCA 12 days later with no clinical symptoms. We treated the mid LAD with implantation of a drug-eluting stent on admission and the SCAD had not progressed 12 days later. Moreover, the SCAD in the distal RCA and distal LAD healed spontaneously 12 days later. He had no recurrent attack, and all SCAD lesions of the RCA and LAD had completely healed 6 months later. Given that SCAD appears in various forms over the clinical course, a strategy of intervention needs careful consideration.

    We report 2 cases of true uterine artery aneurysms diagnosed during pregnancy. Both cases presented with nonspecific symptoms such as urethral obstruction, minimal vaginal bleeding and lower abdominal pain in the 2nd trimester. Both aneurysms were diagnosed by color Doppler ultrasound. In the first...... case labor was induced at 37 + 4 weeks of gestation. However, due to sudden fetal distress and maternal abdominal pain, an emergency Caesarean section was performed during labor, and 3 liters of intra-peritoneal blood were encountered upon laparotomy, secondary to a ruptured uterine artery aneurysm....... In the second case, an elective Caesarean section was scheduled at 38 + 3 weeks of gestation, and the delivery and postpartum period were uncomplicated. Albeit a rare condition, a uterine artery aneurysm should be among the differential diagnosis considered in pregnant women who present with pelvic and vaginal...

  7. Acute multivessel coronary artery occlusion: a case report

    2012-09-01

    Full Text Available Abstract Background In terms of clinical and angiographic findings, multiple simultaneous coronary occlusions in acute myocardial infarction are infrequent, and the mechanism of the occlusions is unclear. Case presentation We herein report a rare case of two simultaneously occluded coronary arteries, one of which subsequently underwent spontaneous lysis. An 88-year-old man had a 3-hour attack of acute crushing retrosternal chest pain. His first electrocardiogram showed ST-segment elevation in the inferior (II, III, and aVF and anterior (V3–V6 leads. His second electrocardiogram in the cardiac care unit showed ST-segment elevation in the inferior leads but ST-segment depression in the anterior leads. Emergency coronary angiography revealed that the right coronary artery was acutely and totally occluded at the midportion and that the proximal and midportion of the left anterior descending coronary artery had an acute thrombus. According to his electrocardiogram and coronary angiography findings, we inferred that the right coronary artery and left anterior descending coronary artery first totally occluded simultaneously, and then the thrombus in the left anterior descending coronary artery spontaneously underwent partial lysis. Therefore, intervention of the right coronary artery was performed followed by injection of glycoprotein IIB-IIIA inhibitor into the left anterior descending coronary artery. He had an uneventful hospital course and was discharged home 10 days later. Conclusion Because patients with multivessel coronary artery occlusion are often in serious condition, abnormal electrocardiographic results must be identified and affected vessel should be opened timely and efficiently to save the myocardium and reduce complications such as congestive heart failure.

  8. Aortic Dissection Occurring 18 Months after Successful Endovascular Repair in an Anatomically Difficult Case of Abdominal Aortic Aneurysm

    Directory of Open Access Journals (Sweden)

    Satoshi Yamamoto

    2013-01-01

    Full Text Available We report an autopsy case of aneurysm dissection that occurred 18 months after the implantation of a Zenith stent graft. A 94-year-old woman, who had undergone an endovascular repair with postoperative reintervention, died of shock due to retroperitoneal hematoma. An autopsy indicated that the stent graft remained firmly fixed to the native aorta, whereas the dissection occurred near the proximal edge of the stent graft but not at the point of attachment between the suprarenal stent hook and the aorta. The luminal surface of the stent graft was almost completely covered with a transparent film with an endothelial cell lining, which might reflect the tissue regeneration observed on histological examination. This was a rare case of acute aortic dissection that occurred 18 months after EVAR, in which the autopsy indicated interesting microscopic findings and the mechanisms underlying the aortic dissection. We believe that aggressive reintervention at the proximal site in elderly women might cause the dissection of the native aorta.

    Thoracic aortic aneurysm/dissection (TAAD) is a potential lethal condition with a rising incidence. This condition may occur sporadically; nevertheless, it displays familial clustering in >20% of the cases. Family history confers a six- to twentyfold increased risk of TAAD and has to be considered in the identification and evaluation of patients needing an adequate clinical follow-up. Familial TAAD recognizes a number of potential etiologies with a significant genetic heterogeneity, in either syndromic or nonsyndromic forms of the manifestation. The clinical impact and the management of patients with TAAD differ according to the syndromic and nonsyndromic forms of the manifestation. The clinical management of TAAD patients varies, depending on the different forms. Starting from the description of patient history, in this paper, we summarized the state of the art concerning assessment of clinical/genetic profile and therapeutic management of TAAD patients.

    The treatment of head and neck cancer with radiotherapy and radical neck dissection has many recognized complications. Radiotherapy in therapeutic doses can produce devascularization and weakening of bone. Radical neck dissection results in altered mechanics of the shoulder girdle and a disruption of normally balanced forces acting on the clavicle. An unusual case of clavicle fracture which is considered to have resulted from an interaction of the effects of these therapies is discussed. An approach for recognizing and distinguishing this entity by its time course, and radiographic and nuclide bone scan appearance is presented.

    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.

    2015-01-01

    Full Text Available Stanford type A aortic dissections often present to the hospital requiring emergent surgical intervention. Initial diagnosis is usually made by computed tomography; however transesophageal echocardiography (TEE can further characterize aortic dissections with specific advantages: It may be performed on an unstable patient, it can be used intra-operatively, and it has the ability to provide continuous real-time information. Three-dimensional (3D TEE has become more accessible over recent years allowing it to serve as an additional tool in the operating room. We present a case series of three patients presenting with type A aortic dissections and the advantages of intra-operative 3D TEE to diagnose the extent of dissection in each case. Prior case reports have demonstrated the use of 3D TEE in type A aortic dissections to characterize the extent of dissection and involvement of neighboring structures. In our three cases described, 3D TEE provided additional understanding of spatial relationships between the dissection flap and neighboring structures such as the aortic valve and coronary orifices that were not fully appreciated with two-dimensional TEE, which affected surgical decisions in the operating room. This case series demonstrates the utility and benefit of real-time 3D TEE during intra-operative management of a type A aortic dissection.

The postexcisional defect, exposing patella, was covered through a regional cutaneous flap of the distal third of the thigh, upper lateral genicular artery-based, measuring 20/10 cm, together with expanded free skin split grafts, applied in proximal third of the leg and distal third of the left thigh. Surgical stages and favorable postoperative evolution are exposed. Selection of a particular surgical procedure, depending on the extent and location of the postexcisional defect, as well as therapeutic alternatives according to the literature data, are also discussed. In conclusion, the lateral genicular artery flap represents a useful surgical procedure for covering anterolateral extended defects of the knee, by bringing pliable, supple and flexible cutaneous tissue, similar to original skin, without bulk or irregularities. Moreover, this flap dissection and transposition to the defect does not involve making microsurgical vascular anastomosis. PMID:27604676

    Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions ≥2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment. PMID:26595501

    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.

    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

  11. Computed tomography of coronary artery anomaly - case report

    International Nuclear Information System (INIS)

    Background: Anomalies of coronary vessels can be described as varies group of congenital heart disease, which can have different level of clinical manifestation and changeable pathophysiological mechanisms. Diagnosis and imaging of vessel course is essential before percutaneous angioplasty intervention and coronary artery bypass grafting as well as before implantation of artificial valve. Case Report: Patient with cardiologic history, previously percutaneous intervention were performed and left circumflex coronary artery were assessed as occluded. Computed tomography revealed anomalous origin of patent circumflex branch arising from right Valsava sinus. Conclusions: Selective percutaneus coronary angiography is challenging in case of coronary anomalies, there are only few indirect symptoms of anomalies. The advantage of computed tomography over classic coronarography is visibility of all patent coronary vessels after single administration of contrast medium. It is possible to describe its anatomic relations, evaluation of walls and its changes

    2015-01-01

    Full Text Available Context. The possibility of cephalic venous hypertension with the resultant facial edema and elevated cerebrospinal fluid pressure continues to challenge head and neck surgeons who perform bilateral radical neck dissections during simultaneous or staged procedures. Case Report. The staged procedure in patients who require bilateral neck dissections allows collateral venous drainage to develop, mainly through the internal and external vertebral plexuses, thereby minimizing the risks of deleterious consequences. Nevertheless, this procedure has disadvantages, such as a delay in definitive therapy, the need for a second hospitalization and anesthesia, and the risk of cutting lymphatic vessels and spreading viable cancer cells. In this paper, we discuss the rationale and feasibility of preserving the external jugular vein. Considering the limited number of similar reports in the literature, two cases in which this procedure was accomplished are described. The relevant anatomy and technique are reviewed and the patients’ outcomes are discussed. Conclusion. Preservation of the EJV during bilateral neck dissections is technically feasible, fast, and safe, with clinically and radiologically demonstrated patency.

    A 51-year-old woman presented with a distal anterior cerebral artery aneurysm (DACAA) manifesting as severe headache and monoparesis of the left lower limb. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, bilateral sylvian fissures, and basal cistern, and a hematoma in the supracallosal region. Angiography showed a large aneurysm (23 x 18 mm) located on the distal end of the azygos anterior cerebral artery (azygos ACA) at the supracallosal portion. T2-weighted magnetic resonance imaging demonstrated the hematoma as a mixed intensity mass, compressing the corpus callosum downward, and the aneurysm as a flow void anterior to the hematoma. Unilateral frontoparietal parasagittal craniotomy was performed with a horse-shoe shaped incision. The aneurysm was clipped via the interhemispheric approach, and the hematoma was aspirated. Postoperative angiography showed disappearance of the aneurysm and intact azygos ACA. The patient was discharged with mild monoparesis, paresthesia of the left lower limb and diagnostic dyspraxia. DACAA almost always arises at or near the genu of the corpus callosum and is often associated with vascular anomaly. In the literature, 22 of 26 cases of large and giant DACAA were located at or near the genu, but only 3 cases, including ours, in the supracallosal area. 11 cases were associated with azygos ACA. Therefore, hemodynamic stress caused by vascular anomaly may be involved in the formation of large or giant DACAA in contrast with cases of normal DACAA. PMID:9789300

    Higher doses and consumption of energy drinks leads to cardiovascular effects and potential consequences. Principal components found in energy drinks such as caffeine, guarana and taurine has been related to dilatation, aneurysm formation, dissection and ruptures. There is no evidence showing an integration of these components and its effects in endothelium and aortic walls due to higher levels of pressure during exercises. We report a case of a 44 years male with celiac trunk and branches dissection due to long-term consumption of energy drinks and intense exercise routine. Our proposition relates cell and vessel walls alterations including elasticity in endothelial wall due to higher blood pressure, resistance by intense exercise routine and long-term consumption of energy drinks.

    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.

    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 .

    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.

    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.

    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.

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

    A 39-year-old patient diagnosed two years previously with Marfan Syndrome (MS) and thoraco-abdominal aneurysm, both presented with the following symptoms: occasional mild effort dyspnea and thoracic pain. The patient started her current illness at 28 weeks of pregnancy with an exacerbation of a deep, oppressive thoracic pain and orthopnea. The echocardiogram showed a 10 cm diameter aortic aneurysm with involvement of the aortic root, tho-racoabdominal and dissection. The computed tomography reported aneurysmatic dilatation of the aortic root and dissection of the thoracic and abdominal portion. Until the delivery of pregnancy the patient was treated successfully with meto-prolol, prazocin, and diuretics. A cesarean section at 29 weeks of pregnancy was practiced. PMID:20602908

    The term ''accordion effect'' is used to describe a mechanical distortion of tortuous arteries mimicking spasm or dissection. This phenomenon has been reported in patients undergoing percutaneous coronary intervention. To our knowledge, this is the first documentation of the accordion effect during carotid artery intervention. Two patients who developed the accordion effect during carotid artery stenting (CAS) are described. Angiograms obtained just after CAS showed a stenosing lesion with wall irregularity at the distal part of the stent. This lesion disappeared and tortuosity of the internal carotid artery developed after withdrawing the guidewire until its floppy segment rested equally on the lesion. In another patient, the lesion did not disappear completely until the guiding catheter had been withdrawn to the proximal portion of the common carotid artery. We conclude that these stenosing lesions reflected the accordion effect. It is essential to differentiate the accordion effect from dissection, spasm, and thrombosis because the management is importantly different. We report our findings and present a review of the literature. (orig.)

    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.

    Full Text Available The external carotid arterial system is a complex vascular system providing nourishment to the territorial areas of the head and neck. The branches of the external carotid artery are the key landmarks for adequate exposure and appropriate placement of cross-clamps on the carotid arteries during carotid endarterectomy. Knowledge of anatomical variation of the external carotid artery is important in head and neck surgeries. Variations in the branching pattern of the external carotid artery are well known and documented. We report a rare case of low-level termination of the external carotid artery. It terminated by dividing into maxillary and superficial temporal arteries deep into the posterior belly of the digastric muscle, one inch below the angle of the mandible. The occipital and posterior auricular arteries arose from a common trunk given off by the external carotid artery. [Arch Clin Exp Surg 2015; 4(3.000: 160-163

  16. Aortic Dissection and Renal Failure in a Patient with Severe Hypothyroidism

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Acute aortic dissection (AAD is a life-threatening condition associated with high morbidity and mortality. The most important recognized acquired cause that leads to dissection is chronic arterial hypertension. With respect to the anuria and renal failure, aortic dissection is not something that is always considered and is still not a very common presentation unless both renal arteries come off the false lumen of the dissection. However, when present, preoperative renal failure in patients with acute type B dissection has been noted to be an independent predictor of mortality. Early recognition and diagnosis is the key and as noted by previous studies as well, almost a third of these patients are initially worked up for other causes until later when they are diagnosed with aortic dissection. Here we present a case of a patient presenting with severe hypothyroidism, long-standing hypertension, and anuria. Through the case, we highlight the importance of having aortic dissection as an important differential in patients presenting with anuria who have a long standing history of uncontrolled hypertension. Pathophysiology relating to severe hypothyroidism-induced renal dysfunction is also discussed.

    Origins and distribution of the human inferior phrenic arteries were studied by dissecting 68 Japanese adult cadavers. The inferior phrenic arteries were usually observed as paired (left and right) vessels. Their origins were summarized as follows: a) the aorta itself (85/138 cases, 61.6%), b) the ventro-visceral arteries (celiaco-mesenteric system of the aorta) including the celiac trunk (39/138 cases, 28.2%) and the left gastric artery (4/138 cases, 2.9%), and c) the latero-visceral arteries (adreno-renal system of the aorta) including the middle adrenal artery (4/138 cases, 2.9%) and the renal artery (6/138 cases, 4.3%). The left and right arteries occasionally originated in common trunk from the aorta, celiaco-mesenteric system or adreno-renal system (22/138 cases, 15.9%). A typological diagram explaining these variations is given. The inferior phrenic arteries, especially the left ones, sometimes issued visceral or esophageal branches. This fact indicates that the inferior phrenic arteries are homologous with the celiac trunk and mesenteric arteries. It is further discussed that the celiac trunk and mesenteric arteries are originally paired vessels, through introduction of our previous typological diagram of the abdominal arteries. PMID:9781269

    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.

    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)

Methods A total of 35 patients with type B aortic dissection diagnosed by clinical and imaging assessments, whose left subclavian artery was involved by dissection, were retrospectively analyzed. All the cases were assessed by CTA before EVAR, their left subclavian arteries were covered by the deployments of stent grafts. The occlusive arteries were recanalized by balloon expanding stents. Results The placements of aortic stent grafts and subclavian arterial stents were successful in all the 35 cases. All the left subclavian arteries were opened during 3—24 months follow-up. The recanalized rate was 100%. Conclusion In the procedures of EVAR the proximal anchoring zone of stent grafts should be chosen in the normal vascular wall to prevent from available dissection caused by therapies. After the deployments of stent grafts which covered left subclavian arteries, the recanalization with chimney technique can

    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. PMID:17349366

    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.

  8. Serum trace elements as nutritional markers in a case with acute aortic dissection

    International Nuclear Information System (INIS)

    Serum trace elements were analyzed by particle induced X-ray emission (PIXE) method in a patient with acute aortic dissection during the supportive process by a Nutrition support team (NST). The patient was a 53-year old male who suffered from acute aortic dissection on March 1, 2007. He received emergent Bentall operation and bow pars total displacement. Since he suffered from diarrhea as a result of hypoalbuminemia and bowel dysfunction, enteral nutrition was not sufficient to maintain adequate intake. Therefore, we also used parenteral nutrition until the 97th disease day. Afterwards, the patient managed only with enteral nutrition. We measured serum trace elements during these periods. Serum trace elements such as Fe, Zn and Se were preserved within normal ranges. On the other hand, Cu gradually decreased until the 54th disease day (44 μg/l) and stayed in the lower levels around the detection limit until the 109th disease day. Thereafter, Cu slightly increased and reached 117 μg/l on the 131st disease day (reference range of serum Cu in adult males: 700-1,300 μg/l). It was suggested that the serum levels of these trace elements might reflect the nutritional stages of the patient and could be useful as clinical markers for nutritional therapies. (author)

    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

    In thoracic surgery, anatomic variations of pulmonary artery increase the risks for vessel injury and critical mistakes during pulmonary artery resection. We report a case of lung cancer with an extremely rare branch, a mediastinal A7 pulmonary artery. Some case reports of the mediastinal pulmonary artery exist until now. However, to the best of our knowledge, this is the first case of a medial basal segmental artery (from the following, it is referred to as A7) branching directly from main pulmonary artery in the literature. Therefore, there is no report that showed three-dimensional computed tomography (3D-CT) and operative findings. So, these information is very useful for thoracic surgeon. A 67-year-old man was admitted to our hospital in order to undergo operation for the treatment of lung cancer. We detected the anomalies preoperatively by 3D-CT. The 3D-CT shows the A7 pulmonary artery branches from the right main pulmonary artery directly. According to previous literature, the cases of a single branch from main pulmonary artery to lower lobe are only five cases. And, the only two of them are right side including our case. In spite of an extremely rare case, we were able to successfully perform a right middle lobectomy because the information obtained from the 3D-CT findings was sufficiently understood preoperatively.

    Full Text Available Objectives Unipolar depression (UPD is a leading cause of global burden of diseases, particularly among the elderly, whose treatment may be challenging. In such cases, ECT is often recommended due to its safety and efficacy. This report presents a case of a 67-year-old male inpatient that developed a rare cardiac complication during ECT. 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.

    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

    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.

  1. The measure for problematic case with middle meningeal artery origin ophthalmic artery in front-temporal craniotomy and a part of DSA. Preservation of visual function

    International Nuclear Information System (INIS)

    Because of the recent development of high-performance 3-dimensional computed tomography (3D-CTA), magnetic resonance angiography (MRA) and the consideration of the risk of digital subtraction angiography (DSA), DSA is not always necessary in performing surgery for cerebral aneurysms. However, DSA was necessary in patients in whom the ophthalmic artery from the internal carotid artery (IC) was not visualized on 3D-CTA or MRA, in order to predict the risk of blindness after front-temporal craniotomy. In this study, we investigated the preoperative evaluation and the surgical procedure for 330 cases of front-temporal craniotomy for surgery of aneurysm over the past 4.5 years. There were 5 cases without ophthalmic artery from IC in DSA or 3D-CTA, 4 cases with an anomalous ophthalmic artery arising from the middle meningeal artery and 1 case with an anomalous ophthalmic artery arising from unknown origin. Microsurgical procedure is needed to preserve the middle meningeal artery in front-temporal craniotomy in these cases with an anomalous ophthalmic artery arising from the middle meningeal artery, because this anomaly places the ophthalmic artery at risk during procedures in which the dura is elevated from the greater and lesser wings of the sphenoid or when the sphenoid ridge is removed in front-temporal craniotomy. Front-temporal craniotomy is difficult in cases with an anomalous ophthalmic artery arising from an unknown origin. (author)

  2. Right Gastroepiploic Artery as an Alternative for Arterial Reconstruction in Living Donor Liver Transplantation

    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.

    Full Text Available Total thyroidectomy can be performed with low rate of injuries of the recurrent laryngeal nerves and parathyroid glands, with appropriate techniques. The paper describes the technique of total thyroidectomy using capsular dissection and the indications of this operation. There are some steps which should be respected: good exposure of the thyroid gland, careful dissection of the superior pole using the avascular plane between superior pole and cricothyroid muscle, medial retraction of the gland, ligating the tertiary (third order branches of the inferior thyroid artery, near the surface of thyroid parenchyma. Using this type of dissection, the recurrent laryngeal nerves are protected, as well as the blood supply of the parathyroid glands. Conclusions: Total thyroidectomy using capsular dissection is the procedure of choice for multinodular goiter, because avoid the completion thyroidectomy for recurrence or occult thyroid cancer.

    The complications of pancreatitis, such as pseudocyst or abscesses, are well known to radiologists. Yet formation of a pseudoaneurysm of the short gastric artery is an uncommon complication of acute pancreatitis. It is also very rare for a psuedoaneurysm of the short gastric artery to cause splenic vein occlusion and the final result is gastric varices. We report here on a case that showed the dramatic effect of embolotherapy for a pseudoaneurysm of the short gastric artery that caused gastric variceal bleeding

    We present a particular case of TRAP (twin reversed arterial perfusion) syndrome, which has a very rarely association of the simultaneous existence of a rudimentary malformed heart and brain, and also other malformations like abdominal wall abnormality, absent bladder with present kidneys, and absence of the lungs, which appear only in a few cases on the receptor twin from this sequence, malformations incompatible with life. A Caucasian 26-year-old pregnant woman, at the first pregnancy, with a monochorionic-diamniotic pregnancy, 26 weeks of gestation was referred to our hospital, for polyhydramnios. The patient delivered a living female newborn, weighing 950 g, with an Apgar score of 2 at one minute - the donor fetus and a second female newborn with multiple malformations, no signs of life and who weighed 2300 g - the receptor fetus. The anatomopathological examination confirmed the TRAP sequence associated with severe facial dysmorphism, bilateral phocomelia and cardiac malformations (rudimentary hypoplastic, univentricular) and a vascular anastomosis between the two umbilical cords. Anemia and cardiac complications which can lead to cardiac failure, appear early during pregnancy and caused the death of the pumping twin. We emphasize that in our case of TRAP sequence, the ultrasound examination established the diagnosis of the syndrome with high accuracy. Therefore, we can conclude that the existence of a rudimentary heart and a vascular anastomosis between the two umbilical cords supports the apparition of TRAP sequence. The early diagnosis of this pathology, the observation of the pregnancy with the help of weekly ultrasounds and the intrauterine interventions can increase the survival chances of the donor fetus from the TRAP sequence.

    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.

    We describe a case of intra-arterial treatment (IAT) of acute posterior circulation occlusion in a patient with a persistent primitive trigeminal artery (PPTA). The patient presented with an acute left sided hemiparesis and loss of consciousness (Glasgow coma score of 5). Computed tomography angiography showed an acute occlusion of the right internal carotid artery (ICA), the PPTA, distal basilar artery (BA), right posterior cerebral artery (PCA), and right superior cerebellar artery (SCA). Stent-retriever assisted thrombectomy was not considered possible through the hypoplastic proximal BA. After passage of the proximal ICA occlusion, the right PCA and SCA were recanalized through the PPTA, with a single thrombectomy procedure. Ten days after intervention patient was discharged scoring optimal EMV with only a mild facial and left hand paresis remaining. PPTA is a persistent embryological carotid-basilar connection. Knowledge of existing (embryonic) variants in neurovascular anatomy is essential when planning and performing acute neurointerventional procedures. PMID:26464287

    Two cases of trigeminal neuralgia associated with the primitive trigeminal artery are reported. From 1981, the authors have treated 131 trigeminal neuralgia patients with microvascular decompression. Among them, we encountered two rare cases of trigeminal neuralgia associated with the primitive trigeminal artery (PTA) and its variant (PTAV). Case 1 is a 74-year-old woman who was admitted to our hospital due to pain of maxilla and mandible. We diagnosed her pain as trigeminal neuralgia. Preoperative angiogram showed the primitive trigeminal artery arising from the cavernous portion of the right internal carotid artery (ICA). She underwent a microvascular decompression operation. We found that her right trigeminal nerve was compressed by the right superior cerebellar artery (SCA) and the right anterior inferior cerebellar artery (AICA). We transferred the offending arteries, and her pain disappeared. Case 2 is a 48-year-old man who was admitted to our hospital due to severe mandibular pain. We diagnosed his pain as trigeminal neuralgia, and he underwent a microvascular decompression operation. His left trigeminal nerve was found compressed by the left SCA and the AICA, and the AICA was arising from the direction of Meckel's cave. His severe pain disappeared completely after operation. Postoperative angiogram of his left ICA showed an aberrant artery arising from the cavernous portion of the ICA, to the region of the left AICA. This aberrant artery is a variant of PTA (PTAV). PTA and PTAV, the so called persistent congenital arteries, are said to accompany aneurysms and other vascular lesions, and affect hemodynamic stress.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2336149

    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.

    Mycotic aneurysms most commonly occur in femoral arteries or the abdominal aorta. Mycotic aneurysm arising from the left subclavian artery is very rare. The morbidity and mortality of ruptured mycotic aneurysms, regardless of their location, remain high despite the current practice of administering an intensive antibiotic regimen. We encountered a case of mycotic aneurysm presenting as mediastinal abscess and arising from in the left subclavian artery. Therefore, we report this case with radiologic findings to remind readers of the possibility of this unusual location of mycotic aneurysm.

    Conclusion: spontaneous IOD can occur in elderly patients who are anticoagulated. Fish oil has not been previously reported as having an association with IOD. This is the first known reported case of spontaneous IOD occurring in association with concurrent use of a bisphosphonate and fish oil. IOD is a rare disorder, and any anticoagulated patients presenting with severe chest pain may need careful investigation prior to definitive management.

    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 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.

  20. Aortic Arch Vessel Anomalies Associated with Persistent Trigeminal Artery: (Report of a Case

    2008-01-01

    Full Text Available Introduction: Developmental anomalies of the aortic arch vessels are well described entities. Persistent trigeminal artery (PTA is the most common type of the four anomalous carotid-basilar anastomoses, and is due to abnormal persistence of what are normal transient communications between the embryonic forebrain and hindbrain arterial systems. Herein we report a previously undescribed variant consisting of coexistence of the PTA, truncus bicaroticus, and di-rect origin of left vertebral artery from aortic arch. "nCase Presentation: A 46 year-old man was admitted in the Namazi hospital with severe nausea, vomiting, severe headache, and decreased level of conscious-ness. Computed tomography scan revealed intraven-tricular hemorrhage with no evidence of subarach-noid hemorrhage. The patient was referred for four-vessel cerebral arteriography to evaluate the entire cerebral vascular anatomy. Arch aortography demon-strated the right subclavian artery as the first branch of the arch. The left vertebral artery arose directly from the arch as the second branch. The third branch consisted of a common trunk giving rise to the right and left common carotid arteries (Truncus Bicaroti-cus. The left subclavian artery arose as the final branch of the aortic arch. Selective angiography con-firmed that left vertebral artery did not arise from the left subclavian artery. Left vertebral artery angiogra-phy revealed a persistent trigeminal artery, with fill-ing of left internal carotid artery and its branches. No aneurysm or any other vascular abnormality was de-tected in this patient. The patient was subsequently managed by evacuation of IVH and ventriculostomy."nDiscussion: The usual configuration of three branches from the aortic arch is found in 60-80% of popula-tion. The left vertebral artery normally originate along the superior portion of the left subclavian ar-tery. However, this artery is subject to a number of variations; among all; the most common

  1. Does thrombolytic therapy harm or help in ST elevation myocardial infarction (STEMI caused by the spontaneous coronary dissection?

    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.

    Congenital single coronary artery is commonly associated with complex congenital heart diseases and manifests in infancy or childhood. But isolated single coronary artery is a rare congenital anomaly which can present as acute coronary syndrome in adults. The aim of the work is to discuss on isolated single coronary artery in two adults presenting as acute coronary syndrome. The first case underwent coronary angiography (CAG) through right radial route, but switched over to femoral for confirmation of diagnosis and due to radial spasm. An aortic root angiogram was done to rule out presence of any other coronary ostia. It revealed a single coronary artery originating from right sinus of valsalva. After giving rise to posterior descending artery branch at crux, it continued in the atrioventricular groove to the anterior basal surface of the heart and traversed as anterior descending artery. There was no atheromatous occlusive stenosis. This is R-I type single coronary artery as per Lipton classification. In the second case, angiography was completed through right radial route. It revealed a single coronary artery arising from right aortic sinus. Anterior descending and circumflex branch were originating from proximal common trunk of the single coronary artery and supplying the left side of the heart. The right coronary artery has diffuse atheromatous disease without significant stenosis in any major branch. This is R-III C type as per Lipton classification. A coronary anomaly of both origin and course is very rare. It may be encountered in adults evaluated for atherosclerotic coronary heart disease. Knowledge and understanding of anatomical types of this congenital anomaly will reduce time, anxiety, complications during CAG and cardiac surgery. PMID:25075168

  3. Superselective uterine arterial infusion and embolization in the treatment of ectopic pregnancies of 56 cases

    International Nuclear Information System (INIS)

    Objective: To probe a simple, safe, and minimally invasive method to treat ectopic pregnancy with preservation of the organs. Methods: Superselective catheterization of uterine artery through cannulation of right femoral artery was achieved in 56 patients with ectopic pregnancy. Location of the lesions involved, feeding arteries, and active bleeding were observed on angiography. 150 mg of methylamine neopterin diluted in 100 ml of saline water was infused slowly into the target artery. Small gelatin spongy particles with size of 0.5 mm in diameter were used to embolize the uterine artery until its branches were totally obliterated. Follow-up was undertaken to observe the results of the treatment. Results: Superselective uterine arterial infusion and embolization were successfully performed in all 56 patients without any related complications. Active bleeding in the peritoneum in 33 eases ceased soon after embolization. The embryos in 13 patients were confirmed to have died by ultrasound two days after the procedure. Beta-HCG value dropped to below 5 U/L within two to twelve days. Hemorrhage in the peritoneum dissolved after seven days in all cases. Mixed mass disappeared after one month. Histerosalpingography was performed three months after the procedure in 19 patients and patent fallopians were demonstrated in 11 patients. Conclusions: Superselective uterine arterial infusion and embolization is a minimally invasive procedure, which can be used to effectively treat ectopic pregnancy by disabling the ectopic embryo and embolizing leaking arteries with the advantages of preserving the fallopian tubes.

    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.

    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.

  6. 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 A spontaneous rupture of an adrenal artery is a rare cause of abdominal pain in pregnancy. We present a case of a pregnant woman who needed to be operated on because of a rupture of the right adrenal artery associated with a fetal bradycardia. An immediate caesarean section was performed. The intra-abdominal palpation identified an extensive retroperitoneal mass near the right kidney and a postoperative computer tomography confirmed an active bleeding near the kidney. For this reason our interventional radiology team, using a right femoral artery approach, performed a flush aortogram and identified the source of bleeding in the right adrenal artery. After two attempts, a coiling of the artery stopped the haemorrhage. The pathogenesis of arterial haemorrhage is still poorly understood although a possible cause could be the excess of hormones during pregnancy, which can lead to a significant arterial wall degeneration. In case of a retroperitoneal bleeding and if the patient is still haemodynamically stable, a transcatheter embolization using microcoils must be considered. This technique is nowadays safe and effective and can be performed within a short time with a lower risk of complications.

    PurposeThe ‘emborrhoid’ technique consists of the embolization of the hemorrhoidal arteries. The endovascular arterial occlusion is performed using coils placed in the terminal branches of the superior rectal arteries. The emborrhoid technique has been modeled after elective transanal Doppler-guided hemorrhoidal artery ligation which has been shown to be effective in hemorrhoidal disease. We report the first 14 cases of our experience with emborrhoid technique.Materials and MethodsFourteen patients with disabling chronic rectal bleeding were treated using the emborrhoid technique (3 women, 11 men). The stage of the hemorrhoidal disease was II (10 patients), III (3), and IV (1). This treatment was decided by a multidisciplinary team (proctologist, visceral surgeon, and radiologist). Seven patients underwent previous proctological surgery. Ten patients had coagulation disorders (anticoagulants or cirrhosis). Superior rectal arteries were embolized with pushable microcoils (0.018).ResultsTechnical success of the embolization procedure was 100 %. Clinical success at 1 month was 72 % (10/14). Of the 4 patients who experienced rebleeding, two underwent additional embolization of the posterior rectal arteries with success. No pain or ischemic complications were observed in 13 patients. One patient experienced a temporary painful and edematous, perianal reaction.ConclusionOur case studies suggest that coil embolization of the superior rectal arteries is technically feasible, safe and well tolerated. Additional studies are needed to evaluate the efficacy of this new ‘emborrhoid’ technique in the management of hemorrhoidal disease.

    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.

    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.

    A variant (PTAV) is the persistence after birth of the fetal carotid-basilar anastomosis between the internal carotid artery and a cerebellar artery. We describe two cases of a PTAV demonstrated on MR angiography. A comparison with a persistant trigeminal artery is made and an explanation of the extended Saltzman classification is given. These variants have only little clinical significance, but their recognition is crucial before surgical or interventional procedures or to understand paradoxical cerebellar lesions. MRA appears inferior to selective angiography in diagnosing these variants. PMID:24148723

  16. Uterine arterial embolization for the treatment of adenomyosis: an analysis of therapeutic results in 80 cases

    International Nuclear Information System (INIS)

    Objective: To discuss the therapeutic effect of uterine arterial embolization in treating adenomyosis. Methods: Uterine arterial embolization was performed in 80 patients with adenomyosis. The patients were followed up for 3, 6, 12 and 24 months after the operation. After the treatment the degree of dysmenorrhea, the menstrual flow and the uterine volume were observed and were compared with those before the treatment. Results: After uterine arterial embolization the clinical symptoms were relieved in all 80 patients. The menstrual flow was markedly decreased, the anemia was obviously improved and the uterine volume was significantly reduced, while the ovary functioning was not apparently affected. The symptom of dysmenorrhea completely disappeared one month after the therapy in 76 cases and four months after the therapy in the remaining 4 cases. Conclusion: Uterine arterial embolization is a mini-invasive and safe therapy with remarkable therapeutic results and few side-effects. Therefore, this treatment can significantly improve the patient's living quality. (authors)

    We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery.

    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.

    Abstract Primary sarcomas of the major blood vessels can be classified based on location in relationship to the wall or by histologic type. Angiosarcomas are malignant neoplasms that arise from the endothelial lining of the blood vessels; those arising in the intimal compartment of pulmonary artery are rare. We report a case of pulmonary artery angiosarcoma in a 36-year old female with pulmonary masses. The patient had no other primary malignant neoplasm, thus excluding a metastatic lesion. G...

    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.

  1. An intractable case of lower gastrointestinal hemorrhage due to radiation colitis. Usefulness of transcatheter arterial embolization

    International Nuclear Information System (INIS)

    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)

    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.

    We presented a rare case of a 64-year-old man with a combined anomaly of the bronchus and pulmonary artery that was detected incidentally. Computed tomography showed a hyperlucent, aerated sequestered segment of the right lower lung with an independent ectopic bronchus, which had no connection to the other airway. The affected segment was supplied by its own aberrant pulmonary artery branch from the right pulmonary trunk. This anomaly cannot be classified with any of the previously reported anomalies.

    A 60-year-old woman was transfer-red to the emergency department of our medical center with worsening chest and back pain. Computed tomography revealed Stanford type B aortic dissection. There was a false lumen from the distal arch to the abdominal aorta just above the celiac artery. Although she was at 1st treated conservatively, she abruptly developed acute renal failure and lower limb ischemia because of an enlarged false lumen, and emergency axillo-femoral bypass surgery was performed with an 8 mm tube graft. However, renal failure gradually worsened, which necessitated continuous hemodiafiltration was performed. Thoracic endovascular aortic repair was then performed, and her renal function recovered.

    2015-12-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Vose Joshua G

    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.

    2005-01-01

    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.

    2014-01-01

    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.

    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.

  1. Subclavian artery injury following blunt trauma: A report of three cases

    2012-04-01

    Full Text Available Subclavian artery injuries are rare in blunt chest trauma, constituting just 1-2 percent of all acute vascular injuries. The diagnosis of injury to the subclavian artery is challenging as a good percentage of patients with such vascular injuries have palpable distal pulses, no signs of any external local trauma and associated injuries often divert the attention of treating physicians. Subclavian artery injuries are the second most common injuries to occur to the aortic arch vessels. The mechanism of injury to these vessels varies from deceleration to traction on upper extremity and neck. Angiography is vital in diagnosis and surgical planning of these patients depends on the site and side of the vascular injuries. Early surgical treatment is an important part of management of these patients. Endovascular treatment is of value in a selected subgroup of subclavian artery injury patients. Reported mortality of subclavian artery injuries varies according to haemodynamic status of patient, time of presentation and other associated injuries. A high degree of suspicion is key to diagnosing these vascular injuries. Early appropriate surgical repair of vascular injury, in combination with aggressive treatment of associated injuries, is important for the optimal outcome of these cases. Here we report three cases of subclavian artery injury, which were successfully treated in Hamad General Hospital by vascular surgery and intensive care teams.

    @@ 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.

  3. Iliac Artery and Vein Injury Without Pelvic Fracture Due To Blunt Trauma: A Rare Case

    Directory of Open Access Journals (Sweden)

    2014-08-01

    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.

    Pulmonary artery sarcoma (PAS) is a rare, poorly differentiated malignancy arising from the intimal layer of the pulmonary artery. Contrast-enhanced chest computed tomography (CT) is a good diagnostic modality that shows a low-attenuation filling defect of the pulmonary artery in PAS patients. An 18-year-old man was referred to our hospital for the evaluation and management of cavitary pulmonary lesions that did not respond to treatment. A contrast-enhanced CT of the chest was performed, which showed a filling defect within the right interlobar pulmonary artery. The patient underwent a curative right pneumonectomy after confirmation of PAS. Although lung parenchymal lesions of PAS are generally nonspecific, it can be presented as cavities indicate pulmonary infarcts. Clinicians must consider the possibility of PAS as well as pulmonary thromboembolism in patients with pulmonary infarcts. So, we report the case with PAS that was diagnosed during the evaluation of cavitary pulmonary lesions and reviewed the literatures. PMID:24734102

  5. Anomalous origin of the left coronary artery from the main pulmonary artery. First reported case in Uruguay diagnosed by multislice tomography

    International Nuclear Information System (INIS)

    Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital heart disease (1 in 300,000 live births or 0.5% of all congenital heart diseases in children), producing myocardial ischemia with left ventricular dysfunction and mitral insufficiency of varying degree (dilated cardiomyopathy). Diagnosis allows curative treatment most likely to return as early as ad integrum is made.The clinical diagnosis is suspected by the presence of dilated cardiomyopathy in infants with an electrocardiogram (ECG) showing a characteristic image and pathognomonic . The diagnosis is confirmed by demonstration of the anatomical origin of the left coronary artery from the main pulmonary artery. This demonstration is done classically color Doppler echocardiography and cardiac catheterization with coronary angiography showing the right coronary artery (dilated) originating from the aorta and circulation intercoronary displayed the left coronary artery in the main pulmonary artery. Currently you have new imaging techniques such as multislice CT, able to demonstrate satisfactorily that anomaly. We report the case of an infant with anomalous origin of the left coronary artery from the pulmonary artery, suspected clinically, anatomically demonstration by multislice CT and confirmed by coronary angiography

  6. Postoperative follow-up of Stanford type A aortic dissections with Spiral-CT and MRI: Normal imaging findings and typical complications

    International Nuclear Information System (INIS)

    Purpose: To demonstrate normal postoperative Spiral-CT and MRI findings and typical complications in patients with aortic repair after Stanford type A aortic dissection. Results: The following postoperative complications were seen: Three pseudoaneurysms which developed at the proximal anastomoses of the Dacron prosthesis in two cases and at the insertion site of the reimplanted left coronary artery after implantation of a composite graft (Bentall procedure) in one case; one re-dissection; one perforation of the false lumen; periprostethic flow in one patient after surgical repair of type A dissection by the graft inclusion technique; progressive dilatation of the false lumen in 4 cases; dilatation of the aortic root in a Marfan patient after replacement of the ascending aorta. Conclusion: Precise knowledge of the surgical technique performed is crucial to accurate postoperative imaging evaluation. MRI is the method of choice in the postoperative follow-up of clinically stable patients with aortic dissections. (orig./AJ)

    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.

    Based on the experience of 42 cases of surgical implantation of hepatic intra-arterial catheters (HIAC) for local chemotherapy, the techniques used are analyzed principally as a function of anatomical variations of the hepatic artery. A conventional procedure (HIAC implanted into gastroduodenal artery) was performed in 60% of cases, while in 26% of patients this was possible only after section of a right and/or left hepatic artery. Atypical implantation was necessary in 14% of cases to ensure complete perfusion of liver. The different methods employed and the reasons for their choice are discussed. PMID:4066801

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

    Institute of Scientific and Technical Information of China (English)

    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.

    2009-01-01

    Background We report on a case of an impar umbilical artery (IUA) in an 18-year-old woman. Case presentation The aorta branched off at level L2 into a ventral IUA and a dorsal aorta. The strong IUA produced the inferior mesenteric artery (IMA), the renal artery of a left-sided duplex kidney, and the right-sided ovarian artery before it turned to the right to merge into the right common iliac artery. From the aorta arose the lumbar arteries, the median sacral artery, lateral sacral arteries, a...

    A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy. Missed injuries in trauma patients are well-described phenomena and implementation of the ATLS® trauma schedule led to a decrease in the number of missed...

    2006-01-01

    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.

  17. Reconstruction of complex shoulder defect in a case of subclavian artery thrombosis.

    Satish, Chetan

    2013-06-01

    We report a case of a 24-year-old man with complex shoulder defect on the right side following a road traffic accident. The patient was found to have a subclavian artery thrombosis in its second part with good collaterals ensuring limb viability. Free-flap reconstruction was not possible because of lack of recipient vascular pedicle nearby. Pedicled flaps routinely used for this area such as pectoralis major and latissimus dorsi myocutaneous flaps could not be used as their vascular pedicles arise from the second and third parts of the axillary artery distal to the subclavian artery thrombosis. The best option we could think was the trapezius myocutaneous flap as its vascular pedicle arises from the first part of the subclavian artery proximal to the thrombosis. This article further establishes the importance of knowing the vascular supply of flaps before their clinical application. In this case the trapezius flap acts as a lifeboat for coverage of the complex shoulder defect as its vascular supply is proximal to the site of subclavian artery thrombosis.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    2014-09-01

    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.

    Temporal artery biopsy (TAB) is performed during the diagnostic workup for giant cell arteritis (GCA), a vasculitis with the potential to cause irreversible blindness or stroke. However, treatment is often started on clinical grounds, and TAB result frequently does not influence patient management. The aim of this study was to assess the need for TAB in cases of suspected GCA.

    Transcatheter arterial chemoembolization (TACE) is known to be an effective palliative treatment for unresectable hepatocellular carcinoma (HCC). Serious complications, such as neutropenic sepsis and hepatic decompensation, are well known. A HCC rupture following TACE is a rare complication; however, it can be life threatening if it occurs. In a 75 year old male patient who subsequently developed capsular rupture of the lipiodol laden mass and several free intraperitoneal chemoembolization agents with hemoperitoneum, we report a case of a ruptured HCC that superficially located arterial enhancing and early wash out mass in the right hepatic dome following TACE.

    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

    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.

    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.

    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.

  17. A STUDY OF VARIANT HEPATIC ARTERIAL ANATOMY AND ITS RELEVANCE IN CURRENT SURGICAL PRACTICE

    Directory of Open Access Journals (Sweden)

    Kavitha Kamath. B.

    2015-03-01

    Full Text Available Background: With increase in the number of laparoscopic procedures, oncologic surgical interventions and organ transplant cases, anatomy and variations of hepatic arterial system have become increasingly important. Variations in these vessels may predispose the patients to inadvertent injury during open surgical procedures or percutaneous interventions. Aims: The present study is intended to contribute to the pre-existing data regarding the variations in the branching pattern of hepatic artery and throw light on their clinical implications. Methods: Extrahepatic branching pattern of hepatic arteries were studied in 40 embalmed cadavers of both sexes by dissection method. Results: Classical text book pattern of hepatic arterial anatomy was seen in 30(75% cases and ten (25% cases showed the presence of aberrant hepatic arteries. 12 aberrant hepatic arteries were seen in these ten cases, eight (20% cases with single aberrant hepatic artery and two (5% with combination of aberrant right and left hepatics. Aberrant right hepatic arteries were seen in four (10% cases and all of them were replaced right hepatics arising directly from celiac trunk. Aberrant left hepatic arteries were seen in eight (20% cases, of which six (15% were accessory, two (5% were replaced and all of them arose from the left gastric artery. Conclusion: Because of high incidence of variations in branching pattern of hepatic artery it is very important to have a thorough knowledge of these variants and identify them so as to prevent iatrogenic injuries and increase rate of success of the surgical and interventional procedures in hepatobiliary region.

    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.

    Infraoptic course of the precommunicating segment of the anterior cerebral artery (A1) is a rare anomaly. Furthermore, the presence of this anomaly associated with persistent trigeminal artery variant has been reported in the literature only once. We present a patient who had infraoptic course of A1 associated with an ipsilateral persistent trigeminal artery variant arising from the right internal carotid artery with no apparent connection to the basilar artery. The persistent trigeminal artery variant supplied to the right posteroinferior cerebellar artery territory. The patient also had hypoplastic left vertebral artery, superior cerebellar arteries originating from posterior cerebellar arteries bilaterally, and a bilobed aneurysm of the anterior communicating artery. The aneurysm was clipped and the infraoptic course was verified during the surgery. The post-operative course was uneventful and a follow-up arteriogram on the 7th postoperative day revealed successful obliteration of the aneurysm. We reviewed the literature with respect to presentation, associated vascular anomalies, imaging, associated cerebral aneurysms and other cerebral abnormalities, and treatment of the associated aneurysms. A discussion of the embryogenesis of this rare anomaly is also provided. PMID:21269759

    2011-06-01

    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. 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.

    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.

    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.

    Full Text Available Median nerve is commonly formed by the union of the lateral and medial cord of the brachial plexus, which embrace the third part of the axillary artery. Formation of a median nerve's loop is a very rare condition. We present a cadaveric case, in which the right median nerve was found at the upper arm forming a fusiform neural loop penetrated by a superficial brachial artery, which continued over the forearm as the radial artery. The literature concerning nerve loops and traversing arteries is discussed, as well as the relevant embryology. We consider that such nerve loops constitute vulnerable sites of the nerve trunk since it is compressed by the pulsation of the abnormal traversing artery. Moreover, neurosurgeons should keep in mind that in case of existing arterial variation, variation of the associated neural structures may co-exist. [Int J Res Med Sci 2015; 3(8.000: 2123-2125

    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.

    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.

    Fibromuscular dysplasia (FMD) involving the coronary arteries is an uncommon but important condition that can present as acute coronary syndrome, left ventricular dysfunction, or potentially sudden cardiac death. Although the classic angiographic “string of beads” that may be observed in renal artery FMD does not occur in coronary arteries, potential manifestations include spontaneous coronary artery dissection, distal tapering or long, smooth narrowing that may represent dissection, intramur...

  12. Remodeling of the pulmonary artery induced by metastatic gastric carcinoma: a histopathological analysis of 51 autopsy cases

    International Nuclear Information System (INIS)

    Gastric carcinoma remains the second commonest cause of cancer deaths worldwide. Presence of the carcinoma cell in the pulmonary artery is serious condition that might cause remodeling of the pulmonary artery. The present study conducted detailed histopathological analyses to elucidate how gastric carcinoma cells may affect the structure and hemodynamics of pulmonary arteries. Remodeling of the pulmonary artery was assessed based on measurements of arterial diameters and stenosis rates from the autopsies, and their correlation were also validated. We additionally calculated 95 percent confidential intervals (CIs) for the rate of stenosis in groups of pulmonary arteries of different caliber zones (under 100, 100 to 300, and over 300 micrometer). The right ventricular thickness was measured and examined whether it correlated with the rate of pulmonary arterial stenosis. A total of 4612 autopsy cases were recorded at our institute, among which 168 had gastric carcinoma. Finally, 51 cases of the gastric carcinoma were employed for the study which had carcinoma cells in the lumen of the pulmonary artery. The mean right ventricular wall thickness of these cases was 3.14 mm. There were significant positive associations between the rates of pulmonary arterial stenosis and right ventricular thickness from pulmonary arteries of diameter under 100, 100 to 300, and over 300 micrometer. In these zones, 31, 31, and 33 cases had rates of pulmonary arterial stenosis that were below the lower limit of the 95 percent CI values, respectively. On the other hand, among cases with significant pulmonary stenosis, 17 of 18 cases with stenosis in the over 300 micrometer zone involved pulmonary arteries of both in the under 100 and 100 to 300 micrometer zones. One-third of autopsy with advanced gastric carcinoma had carcinoma cells in lumen of pulmonary artery, but implantation and proliferation may be essential to induce intimal thickening that causes an increasing of pulmonary arterial

    False aneurysm of the subclavian artery is an uncommon complication. Most frequently this pathology is caused by fracture of clavicle, however other causes also can exist. We present a case of diagnosis and endovascular treatment of a false aneurysm of the right subclavian artery in a 31-years-old man, heroin addict, who performed multiple injections into the right subclavian artery. At admission he had paresis and decreased sensitivity in the right arm due to compression neuritis of the brac...

    The occurrence of an acute myocardial infarction (MI) following a scorpion sting has been very rarely reported in the previous literature. Possible pathogenetic mechanisms include severe hypotension due to hypovolaemic shock and coronary spasm with subsequent thrombosis of coronary vessels developed after the release of vasoactive, inflammatory and thrombogenic substances contained in the scorpion venom. All of the previously reported cases had normal coronary angiogram. We report a case of a 65-year-old woman who presented with severe scorpion sting and was treated with prazosin. But a few hours later, she developed acute anterior wall MI. Coronary angiogram revealed the presence of significant stenosis in coronary arteries. As acute MI owing to significant coronary artery disease can be evident after severe scorpion envenomation, so every case of acute coronary syndrome following scorpion sting needs early diagnosis, thorough cardiovascular evaluation and appropriate treatment.

    Vasospasm that develops in association with ergotamine use is a rarely seen but well-understood complication. A case is presented here of multiple fractures in which arteriospasm affecting all the arteries of the lower limb on the same side occurred 10 days post-trauma. In this case, the arteriospasm resulting from ergotamine addiction and high doses of ergotamine, which may be confused with post-traumatic angiospasm, was treated with a marcaine infusion by epidural catheter and heparin, iliomedin and nitronal infusion intravenously. This clinical condition should be borne in mind for all trauma cases determined to have arterial vasospasm, and the use of ergotamine must be queried when taking the anamnesis from the patient.

    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.

    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.

    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 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.
