    A 70-year-old man presented to accident and emergency with an isolated anteriorly dislocated shoulder, in the absence of a concomitant fracture. There was no neurovascular deficit at presentation, and the shoulder was reduced under sedation, using the Kocher's technique. Following this, the patient developed signs of hypovolaemic shock. Clinical examination revealed an expanding fullness in the deltopectoral area, with compromise of the limb neurovascular status. CT imaging confirmed an expanding haematoma from the axillary vessels, restricting left lung expansion. Once resuscitated, the patient was transferred to theatre for exploration of the bleeding vessels. Intraoperative findings included an avulsed anterior circumflex humeral artery that was subsequently ligated. Postoperatively, the patient developed axillary, radial, median and ulnar nerve neuropraxia, which improved clinically prior to discharge. The patient was ultimately discharged home after a lengthy inpatient stay. PMID:26969353

    Full Text Available Aim: Crush injuries of the foot are often associated with partial or complete degloving of the heel pad. The purpose of this study is to present an algorithm for the management of various types of heel pad avulsion injuries, including hyperbaric oxygen (HBO therapy in the treatment regimen. Methods: We present a prospective study of 27 patients with various types of heel pad avulsion managed in our institution from December 2012 to June 2013. Heel pad avulsion injuries were classified according to the angiosomal pattern. Partial or complete avulsions were classified and treated accordingly. HBO therapy was administered postoperatively. The postoperative period, hospital course, and follow-up were documented in patients with heel pad avulsion injuries. Results: Of 27 patients, 20 cases presented with partial avulsion and 7 cases were complete avulsion. Of 20 cases of partial avulsion, one of the flaps was anchored with K-wire. Nineteen cases of partial heel pad avulsion were managed by suturing. Eight patients out of 20 required skin grafting as a secondary procedure at a later date. Out of 7 cases of complete avulsion, one was managed by full-thickness skin grafting, one case by reverse sural artery flap coverage, and four cases were managed by free tissue transfer. No flap revisions were required, and no complications were experienced for the transferred flaps. Conclusion: HBO therapy may be a useful adjunct in the treatment of heel pad avulsion injuries.

    2010-01-01

    Full Text Available We report a rare case of orbital swelling presenting one year after head trauma. An initial fine needle aspiration cytology revealed it to be an infected organizing hematoma. However, broad-spectrum antibiotics did not resolve the infection and the orbital lesion continued to grow in size, as evaluated by magnetic resonance imaging. Incisional biopsies were done, which were reported as orbital actinomycosis. Patient has responded well to treatment with penicillin. This case is of interest due to the delayed presentation of an orbital complication of head trauma and the rare infection with actinomyces. It also highlights the importance of using appropriate antibiotics, as well as the need for long-term treatment.

    Full Text Available ABSTRACT Introduction Complete ureteral avulsion is one of the most serious complications of ureteroscopy. The aim of this report was to look for a good solution to full-length complete ureteral avulsion. Case presentation A 40-year-old man underwent ureteroscopic management. Full-length complete avulsion of ureter occurred during ureteroscopy. Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis were performed 6 hours after ureteral avulsion. The patient was followed-up during 34 months. Double-J tube was removed at 3 months after operation. Twenty three months after the first operation, the patient developed hydronephrosis because of a new ureter upside stone, then rigid ureteroscopy and holmium laser lithotripsy were used successfully. Conclusion Pyeloureterostomy plus greater omentum investment outside the avulsed ureter and ureterovesical anastomosis may be a good choice for full-length complete ureteral avulsion.

  12. Replantation of ring avulsion amputations

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available Replantation of ring avulsion injuries is a challenge because of the long segment damage to the vessels and intrinsic damage caused to soft tissues at the proximal edge of the amputation. Eight patients with total ring avulsion amputations underwent microsurgical replantation in the period 1994 to 2002. Arterial repair was done by direct vessel suture in three patients, interposition vein grafts in two and cross anastomosis of the digital arteries in three patients. Venous anastomosis was carried out by mobilization and direct suture in seven patients and vessel transfer from the adjacent finger in one patient. Seven of the eight replantations were successful, while one patient had a partial failure. At a minimum follow-up of one year, these patients showed good functional and cosmetic recovery. All successful patients were happy with the outcome and none have requested for amputation, even those whose results were not functionally adequate. However, in addition to technical factors, it is important to evaluate the patient's motivation to undergo not only the long surgery, but also multiple secondary procedures and regular supervised physiotherapy. We also describe a simple method which prevents the soft tissues inside the degloved digit from becoming wrapped around the K wire during bony fixation, thus making one step of this technically challenging procedure a little easier.

    We describe a patient with ascending tetraparesis following stroke. The patient presented initially with spastic paraparesis which acutely evolved to tetraparesis with abulia. Magnetic resonance imaging revealed acute infarctions in the bilateral medial frontal regions but not in the brainstem or spinal cord. Multiple infarctions in the anterior cerebral artery territory appeared to originate from artery to artery embolism. The present case provides distinct clinical features of anterior cerebral artery syndrome which mimic myelopathy or brainstem lesions. PMID:17903956

    2015-10-01

    Dorsal talus avulsion fractures occurring along the supination line of the foot can cause pain and discomfort. Examination of the foot and ankle using the Ottawa ankle rules does not include examination of the talus, an injury here is easily missed causing concern to the patient. This is a retrospective study carried out in a major trauma centre to look at the assessment and diagnosis of all patients with a dorsal talus and navicular avulsion fractures over a one year period. Nineteen patients with an isolated dorsal talus avulsion fracture and five patients with an isolated dorsal navicular fracture were included. The correct diagnosis was made in 12 of patients with isolated dorsal talus avulsion fractures, 7 patients were given an incorrect diagnosis after misreading of the radiograph. Four patients with a dorsal navicular avulsion fracture were given the correct diagnosis. If not correctly diagnosed on presentation patients can be overly concerned that a 'fracture was missed' which can lead to confusion and anxiety. Therefore these injuries need to be recognised early, promptly diagnosed, treated symptomatically and reassurance given. We recommend the routine palpation of the talus in addition to the examination set out in the Ottawa Ankle Rules and the close inspection of plain radiographs to adequately diagnose an injury in this area.

    Full Text Available Embryonic carotid – basilar anastomosis when persistent in adult life can present with a variety of neurological symptoms. We present a patient with isolated intermittent vertigo attributable to the embryonic anastomosis and describe the different types of persistent trigeminal artery. A 76-year-old Caucasian man presented with isolated intermittent vertigo and symptoms suggestive of anterior and posterior circulation strokes. Impaired vasomotor reactivity was demonstrated on insonation of the anterior and posterior cerebral arteries in this patient with a persistent left trigeminal artery and 75% stenosis of the left internal carotid artery (ICA. The symptom of intermittent vertigo resolved with carotid endarterectomy. Decreased flow across the stenotic segment of the ICA which subserved the posterior circulation resulted in basilar insufficiency. Hypoperfusion to the flocculonodular lobe supplied by the anterior inferior cerebellar artery is a likely cause for the intermittent vertigo.

  1. Modeling coupled avulsion and earthquake timescale dynamics

    River avulsions and earthquakes can be hazardous events, and many researchers work to better understand and predict their timescales. Improvements in the understanding of the intrinsic processes of deposition and strain accumulation that lead to these events have resulted in better constraints on the timescales of each process individually. There are however several mechanisms by which these two systems may plausibly become linked. River deposition and avulsion can affect the stress on underlying faults through differential loading by sediment or water. Conversely, earthquakes can affect river avulsion patterns through altering the topography. These interactions may alter the event recurrence timescales, but this dynamic has not yet been explored. We present results of a simple numerical model, in which two systems have intrinsic rates of approach to failure thresholds, but the state of one system contributes to the other's approach to failure through coupling functions. The model is first explored for the simplest case of two linear approaches to failure, and linearly proportional coupling terms. Intriguing coupling dynamics emerge: the system settles into cycles of repeating earthquake and avulsion timescales, which are approached at an exponential decay rate that depends on the coupling terms. The ratio of the number of events of each type and the timescale values also depend on the coupling coefficients and the threshold values. We then adapt the model to a more complex and realistic scenario, in which a river avulses between either side of a fault, with parameters corresponding to the Brahmaputra River / Dauki fault system in Bangladesh. Here the tectonic activity alters the topography by gradually subsiding during the interseismic time, and abruptly increasing during an earthquake. The river strengthens the fault by sediment loading when in one path, and weakens it when in the other. We show this coupling can significantly affect earthquake and avulsion

    ABSTRACTS The apophyseal fracture or avulsion of the greater trochanter occurs in skeletally immature patients. It has at etiological factors indirect mechanisms (avulsion) and direct mechanisms (trauma on the trochanter), the latter being the most common. The clinical presentation is easily identified and a simple X- ray can confirm the diagnosis. Regardless of the treatment chosen, this pathology has a high correlation with osteonecrosis of the femoral head, even as a rare fact, however with innocent appearance, on this pathology.

    2014-01-01

    Full Text Available Introduction. Splenic artery Pseudoaneurysm, a complication of chronic pancreatitis, presenting as massive hematemesis is a rare presentation. Case Report. We present a case of 38-year-old male admitted with chief complaints of pain in the upper abdomen and massive hematemesis for the last 15 days. On examination there was severe pallor. On investigating the patient, Hb was 4.0 gm/dL, upper GI endoscopy revealed a leiomyoma in fundus of stomach, and EUS Doppler also supported the UGI findings. On further investigation of the patient, CECT of the abdomen revealed a possibility of distal pancreatic carcinoma encasing splenic vessels and infiltrating the adjacent structure. FNA taken at the time of EUS was consistent with inflammatory pathology. Triple phase CT of the abdomen revealed a splenic artery pseudoaneurysm with multiple splenic infarcts. After resuscitation we planned an emergency laparotomy; splenic artery pseudoaneurysm densely adherent to adjacent structures and associated with distal pancreatic necrosis was found. We performed splenectomy with repair of the defect in the stomach wall and necrosectomy. Postoperative course was uneventful and patient was discharged on day 8. Conclusion. Pseudoaneurysm can be at times a very difficult situation to manage; options available are either catheter embolisation if patient is vitally stable, or otherwise, exploration.

    Full Text Available The nail is a subject of global importance for dermatologists, podiatrists and surgeons. Nail avulsion is a frequently undertaken, yet simple, intriguing procedure. It may either be surgical or chemical, using 40% urea. The former is most often undertaken using the distal approach. Nail avulsion may either be useful for diagnostic purposes like exploration of the nail bed, nail matrix and the nail folds and before contemplating a biopsy on the nail bed or for therapeutic purposes like onychocryptosis, warts, onychomycosis, chronic paronychia, nail tumors, matricectomy and retronychia. The procedure is carried out mostly under local anesthesia with or without epinephrine (1:2,00,000 dilution. Besides the above-mentioned indications, the contraindications and complications of nail avulsion are briefly outlined.

    International Nuclear Information System (INIS)

    This paper presents a calcaneal fracture pattern that appears to be unique to diabetic patients. Radiographs and clinical records of 58 patients with calcaneal fractures were evaluated, 18 were diabetic and 40 nondiabetic. All 18 diabetic patients were insulin dependent and had clinically evident peripheral neuropathy. Thirteen had juvenile-onset diabetes. The average time from the diagnosis of diabetes mellitus to insufficiency fracture was 21 years. Sixteen of the diabetic patients had no history of significant trauma, and 13 of them had insufficiency avulsion fractures limited to the posterior third of the calcaneus

    A 55-year-old woman was admitted with a 3 days history of increasing lethargy with bradyphrenia and apathy. She progressively developed severe somnolence with marked abulia, right hemiparesis, right hemianopsia, and pseudobulbar palsy. Brain magnetic resonance imaging showed the rare image of bilateral acute anterior choroidal artery infarction. Pseudobulbar mutism and in rare cases abulia have been described in acute anterior choroidal artery infarction contralateral to an older lesion in mirror position. Although neurologic deterioration is not infrequent in anterior choroidal artery territory infarcts, the absence of focal neurologic signs on admission is rare and did not raise suspicion of acute stroke.

    Popliteal artery entrapment syndrome (PAES) is a rare condition that should be suspected in a young patient with exertional lower extremity pain. We report the case of an 18-year-old female volleyball player with bilateral exertional lower extremity pain who had been previously diagnosed with tendinitis and periostitis. Diagnostic studies showed entrapment of the left popliteal artery and the left anterior tibial artery. To our knowledge, there has only been 1 previous report of anterior tibial artery involvement in PAES. PMID:24880061

    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.

    Avulsion fractures of the apophysis of the iliac crest have rare incidence and are little known. In this article, we report the case of an 11-year-old female patient who presented this injury after indirect trauma. From careful radiographic analysis, an avulsion fracture of the iliac crest was identified. It was decided to use nonsurgical treatment comprising analgesia and load restriction. This case report emphasizes the importance of suspecting avulsion fractures in cases of low-energy trauma, and also guides the treatment, so as to prevent functional deficit and deformities.

    Full Text Available Introduction: Total scalp avulsion is a serious injury, commonly occurring in Indian females working with industrial and agricultural machines. Their long hairs often get caught in a rapidly revolving machines, resulting in total avulsion of scalp. Lack of education and awareness in Indian villages often result in these patients coming late to the hospitals when replantation is not possible and scalp reconstruction remains the only available option. Materials and Methods: We performed our study on 22 cases of scalp avulsion injury presented to us between June 2007 and April 2012 at Department of Burn, Plastic & Reconstructive Surgery, SMS Hospital, Jaipur. In all of them a free tissue transfer was performed as an elective procedure. Results: Twenty two patients underwent free tissue transfer and followed up for an average period of 6 months. All patients included in this study were females with mean age of 28 yrs. Five patients in our study reported with partial necrosis of the free flaps which were subsequently managed with split-thickness skin graft (STSG. Two patients reported total necrosis of the flap which was re-operated using latissimus dorsi along with serratus anterior muscle (LDSA from the contralateral side. Conclusion: As scalp avulsion because of rapidly rotating machine leads to large size defect not amenable for local tissue reconstruction. We performed reconstruction using LDSA and omental free flaps with split thickness skin graft (STSG for large scalp defect and achieved good and stable soft tissue cover with satisfactory cosmesis.

  10. Radiological findings in cervical radicular avulsion

    International Nuclear Information System (INIS)

    Special aspects of examination techniques and positive myelographic findings in cervical radicular avulsion are reported. In addition, the possibilities and limits of myeloscintigraphy are discussed. Some observations and experiences with neuroradiological diagnosis of cervical radicular avulsion are reported which are of importance for the prognosis in brachial plexus injuries. It is determined that no direct relationship between myelographic-findings and nerve functions damage exists. The possibility of regeneration in serious traumatic injuries with extensive dural avulsion is demonstrated in two cases. Despite neuroradiological findings suggesting severe damage and the possibility of functional restitution is emphasized. (orig.)

    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

    2003-02-01

    Full Text Available PURPOSE: Report and review the literature on ureteral avulsion as a rare complication of ureteroscopy. MATERIALS AND METHODS: We analyzed 3 cases of ureteral avulsion in a series of 4,645 ureteroscopic procedures performed from January 1990 to December 2001. We especially report the different managements for this complication. RESULTS: Due to the different extent of the injury, each patient was treated in a particular way, including a patient managed by means of an endourological approach. CONCLUSIONS: When performing ureteroscopy or using Dormia baskets, one should always bear in mind the possibility of serious complications, including ureteral avulsion or perforation. The use of an extremely careful technique of ureteral insertion, the mandatory placement of a safety guidewire, and a working guidewire, all minimize the risk of untoward events.

  2. DISTAL TRICEPS AVULSION: A CASE REPORT

    Directory of Open Access Journals (Sweden)

    Ramkumar Reddy

    2015-05-01

    Full Text Available Triceps rupture is an uncommon injury. Fracture of olecranon or a dislocation / fracture is most often common injury for similar mechanism of fall. It is commonly associated with anabolic steroid use, weight lifting, and direct laceration. Risk factors include local steroid injection, olecranon bursitis, and hyperparathyroidism. Distal triceps rupture is usually caused by a fall on an outstretched hand. Eccentric loading of a contracting triceps has been implicated. Initial diagnosis may be difficult because a palpable defect is not always present. Pain and swelling may limit the ability to evaluate strength and elbow range of motion. Although plain radiographs are helpful in ruling out other elbow pathology, MRI is used to confirm the diagnosis, classify the injury, and plan management. Incomplete tears with active elbow extension against resistance are managed non - surgically. Surgical repair is indicated in active persons with complete tears and for incomplete tears with concomitant loss of strength. Good to excellent results have been reported with surgical repair in triceps, even for chronic tears. BACKGROUND: Distal triceps tendon avulsions occur very infrequently, and the diagnosis is often missed when the injury is acute. The literature provides little guidance regarding treatment or the outcome of these injuries. The goal of this report was to report our experience with the diagnosis, timing and technique of surgical treatment, and outcome of treatment of distal triceps tendon rupture.

    Injuries to the nose can be severe from both a functional and cosmetic perspective. After suffering a dog bite to the central part of the face, an 18-year old woman underwent replantation of the avulsed tissue with the help of microsurgical arterial anastomosis. A venous anastomosis was impossible and venous congestion was treated with leech therapy. Subsequent skin necrosis occurred after a few days and the replantation was revised, revealing healthy tissue immediately below. The defect was covered with a full-thickness skin graft. At follow-up review eight months later, the functional and cosmetic result was satisfactory. To our knowledge, this is one of few cases where an injury of this severity healed with a cosmetically acceptable result. PMID:26673050

    Patients who have sustained an avulsion fracture and present clinically during the healing phase of the injury may manifest a mass that clinically and radiographically mimics a malignant neoplasm. A 15-year-old male soccer goalkeeper presented with a large ossified mass in the soft tissues overlying the right hip 6 months after experiencing a popping sensation in his hip joint during a game. Although an osteosarcoma was suspected clinically and radiographically, a Tru-Cut needle biopsy of the lesion revealed reactive bone formation. Correlation of the clinical, radiographic, and pathologic findings indicated an avulsion fracture of the anterior inferior iliac spine with abundant reactive ossification in the soft tissues. The healing phase of an avulsion fracture may clinically and radiographically be mistaken for neoplasia. In such cases, a Tru-Cut needle biopsy may reveal the reactive nature of the process.

    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.

    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

    Avulsion of the brachial plexus was documented in a Great Horned Owl (Bubo virginianus). A fractured scapula was also present. Cause of these injuries was not known but was thought to be due to trauma. Differentiation of musculoskeletal injury from peripheral nerve damage can be difficult in raptors. Use of electromyography and motor nerve conduction velocity was helpful in demonstrating peripheral nerve involvement. A brachial plexus avulsion was suspected on the basis of clinical signs, presence of electromyographic abnormalities in all muscles supplied by the nerves of the brachial plexus and absence of median-ulnar motor nerve conduction velocities.

  11. Avulsion fractures of the anterior inferior iliac spine: spectrum of imaging findings

    International Nuclear Information System (INIS)

    Avulsive injuries of the pelvic aphophyses are relatively common among 13-18 year old athletes, particularly among soccer players in Brazil. Diagnosis is made upon clinical and imaging findings. These lesions show three distinct phases: acute, repair and consolidation phases. Although acute and consolidation phases usually represent no diagnostic challenge, the repair phase may appear as an aggressive process on diagnostic images simulating neoplasic lesions. In this paper, the authors present the imaging findings of patients with avulsion of the anterior inferior iliac spine on plain radiographs, computerized tomography and magnetic resonance imaging, emphasizing the typical features of the three evolutive phases of these lesions.

    A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported. The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair. There was a good functional result following minimally invasive pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture. There are no previous reports of similar pseudo-arthrosis repairs, and other aut...

  13. Marrow MR signal abnormality associated with bilateral avulsive cortical irregularities in a gymnast

    International Nuclear Information System (INIS)

    Abnormal marrow signal and marrow enhancement have not been described in association with benign avulsive cortical irregularity. We present the case of an 11-year-old gymnast with such findings that partially resolved over time. The marrow MR abnormalities are believed to represent an extension or spectrum of findings associated with avulsive cortical irregularity, and should not instantly suggest infection or malignancy, as has been previously indicated. Careful and close clinical and radiological follow-up is required to confirm its benign course. (orig.)

    Simultaneous subarachnoid hemorrhage and infarction is a quite rare presentation in a patient with a spontaneous dissecting aneurysm of the anterior cerebral artery. Identifying relevant radiographic features and serial angiographic surveillance as well as mode of clinical manifestation, either hemorrhage or infarction, could sufficiently determine appropriate treatment. Enlargement of ruptured aneurysm and progressing arterial stenosis around the aneurysm indicates impending risk of subseque...

    Full Text Available The diagnosis of cervical spinal root avulsion in patients with brachial plexus injuries is major challenge of the present day with the available investigatory procedures. To validate the use of the paraspinal electromyography was done in20 successive patients who all had sustained injuries to their upper limb nerves following road traffic accidents. Electromyographic abnormalities indicative of root avulsion were identified. All of them underwent explorative surgery. The results of the paraspinal electromyography were correlated with the intra-operative findings. Paraspinal electromyography was abnormal in six and normal in 14. All the six patients with abnormal results had evidence of multiple spinal root avulsion. Among those with normal paraspinal electromyography, two showed single spinal root avulsion and in the remaining 12 they were intact. The sensitivity of this test was 75% specificity 100% positive predictive value 100% and negative predictive value 85%. Paraspinal electromyography is an useful test in identifying cervical root avulsions because of its high positive predictive value. However with single root avulsion the sensitivity of the test falls. Somato sensory evoked potential and magnetic resonance imaging studies may be valuable adjuncts in diagnosing such cases.

    In patients with diabetes mellitus, cardiovascular disease is the principal cause of mortality and chest pain is the most frequent symptom in patients with stable and acute coronary artery disease. However, there is little knowledge concerning the pervasiveness of uncommon presentations in diabetics. The symptomatology of acute coronary syndrome, which comprises both pain and non-pain symptoms, may be affected by traditional risk factors such as age, gender, smoking, hypertension, diabetes, and dyslipidemia. Such atypical symptoms may range from silent myocardial ischemia to a wide spectrum of non-chest pain symptoms. Worldwide, few studies have highlighted this under-investigated subject, and this aspect of ischemic heart disease has also been under-evaluated in the major clinical trials. The results of these studies are highly diverse which makes definitive conclusions regarding the spectrum of atypical presentation of acute and even stable chronic coronay artery disease difficult to confirm. This may have a significant impact on the morbidity and mortality of coronary artery disease in diabetics. In this up-to-date review we will try to analyze the most recent studies on the atypical presentations in both acute and chronic ischemic heart disease which may give some emphasis to this under-investigated topic.

  2. MRI of radiographically occult ischial apophyseal avulsions

    International Nuclear Information System (INIS)

    Acute avulsions of unossified ischial apophyses in children may go undetected on radiography. Therapy includes rest and rehabilitation; however, substantial displacement may require surgery. Our purpose is to illustrate the utility of MRI in the detection of these radiographically occult injuries in skeletally immature children. This retrospective study of more than 5 years included children with ischial avulsions who were evaluated with both radiography and MRI within 3 weeks of acute injury. Initially, radiographs were reviewed to identify those children with unossified ischial apophyses. Subsequently, their MRI examinations were assessed for physeal disruption, bone/soft tissue edema, periosteal/perichondrial elevation and disruption. Initial and follow-up radiographs (if available) were reviewed. Patient age, symptoms and offending activity were determined from clinical records. Five children met inclusion criteria. All initial radiographs were normal. MRI showed: edema (n = 5), periosteal elevation (n = 4), periosteal/perichondrial disruption (n = 4), >5.5 mm displacement (n = 0). Follow-up radiographs in two children (2 and 2.5 months from MRI) showed osseous ischial irregularity. The apophyses remained unossified. Acute unossified ischial apophyseal avulsions in children may be radiographically undetected. In the setting of correlative clinical symptoms, MRI can be used to identify these injuries and to help direct appropriate therapy. (orig.)

    A 55-year-old female without a history of coronary artery disease, hypertensive for the past 17 years, was admitted with resting chest pain. Electrocardiography revealed a negative T-wave in anterior chest leads. Coronary angiography visualised anomalous coronary anatomy, with a common origin of the right coronary artery and the left main coronary artery in the right sinus of Valsalva serving as a common coronary trunk. It should be emphasised that T-wave abnormalities and chest angina may be related to this congenital coronary anomaly. PMID:26702282

    Full Text Available Abstract Background Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications. Case presentation Here we describe a case of hepatic artery thrombosis after living-donor liver transplantation which was not preceded by signs of liver failure but rather by an episode of acute psychosis. After re-transplantation the patient recovered without sequelae. Conclusion This case highlights the need to remain cautious when psychiatric disorders occur in patients after liver transplantation. The diagnostic procedures should not be restricted to medical or neurological causes of psychosis alone but should also focus vascular complications related to orthotopic liver transplantation.

    Full Text Available Hemangioendotheliomas are classified as epithelioid hemangioendothelioma(EHE, retiform hemangioendothelioma, composite hemanioendothelioma, Kaposiform hemangioendothelioma (with or without Kasabach-Merritt syndrome, and Spindle cell hemangioendothelioma. The latter two types of hemangioendotheliomas usually follow a benign course, in contrast to the other types of hemangioendotheliomas, which are considered as a low grade malignant sarcoma with unpredictable prognosis. EHE's are rare tumors, mostly described in organs particularly the lungs and liver. Though endothelial in origin, EHE's reported to originate from small sized arteries are extremely rare. We report a very rare case of EHE arising from the temporal artery showing a peculiar presentation.

  7. Possible Complications of Ureteroscopy in Modern Endourological Era: Two-Point or “Scabbard” Avulsion

    2014-01-01

    Full Text Available Indication has led ureteroscopy to be a worldwide technique, with the expected appearance of multiple types of complications. Severe complications are possible including ureteral perforation or avulsion. Ureteral avulsion has been described as an upper urinary tract injury related to the action of blunt trauma, especially from traffic accidents, being the mechanism of injury, the result of an acute deceleration/acceleration movement. With the advent of endourology, that term is also applied to the extensive degloving injury resulting from a mechanism of stretching of the ureter that eventually breaks at the most weakened site, or ureteral avulsion is referred to as a discontinuation of the full thickness of the ureter. The paper presents a case report and literature review of the two-point or “scabbard” avulsion. The loss of long segment of the upper ureter, when end-to-end anastomosis is not technically feasible, presents a challenge to the urological surgeon. In the era of small calibre ureteroscopes these complications, due to growing incidence of renal stones will become more and more actual. Our message to other urologists is to know such a complication, to know the ways of treatment, and to analyse ureteroscopic signs, when to stop or pay attention.

    Full Text Available The anterior inferior iliac spine (AIIS and the anterior superior iliac spine (ASIS avulsion fracture is a rare injury of pelvis. It usually occurs during the sport activities especially in football while hitting the ball. It is commonly misdiagnosed so that a detailed history and physical examination have a great importance. We present two cases of AIIS and ASIS avulsion fracture. Both of the patients applied to outpatient clinics with hip pain and difficulty in walking. History revealed the complaints started after hitting the ball during the football match and hip movements were limited. The patients were fifteen and sixteen years and after physical examination and radiological evaluation, avulsion fracture of the AIIS and the ASIS were diagnosed. Patients were treated conservatively with non-steroidal anti-inflammatory drugs and limited weight bearing with crutches for a month. The patients were free of pain and had full range of hip movements after one month period. At the end of the second month patients returned to active sports. AIIS and ASIS avulsion fractures are more common in adolescent football players but clinicians sometimes fail to diagnose this rare injury. We emphasize the importance of the detailed history and clinical examination and direct radiography could be enough for the diagnosis.

    Dental trauma, particularly tooth avulsion, is a frequent cause of tooth loss in children, adolescents, and young adults. The avulsed tooth should be immediately reimplanted in its alveolus. This procedure can be performed by anyone at the accident site and not only by dental surgeons. Therefore, the purpose of this study is to evaluate the knowledge of sixth graders of the city of Araçatuba, SP, about dental avulsion and tooth reimplantation through a structured and standardized survey. Our sample consisted of 778 students. The data collected was processed using the program EPIINFO 2000. Most students were around 12 years of age and 94.5% related to practice some kind of sports. Results demonstrated that the possibility of tooth reimplantation after dental avulsion is not acknowledged among these students and dental traumatism was associated to caries, toothache, and use of orthodontic appliances. Only 18.9% of the students associated dental traumatism to an impact trauma; 3.6% would store the tooth in milk, and 3.1% believed the tooth could be reimplanted by anyone present at the accident site. In summary, the results show an overall the lack of knowledge about dental traumatism and highlight the need of special programs designed to educate school-aged students about emergency procedures to handle cases of dental traumatisms.

    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.

    Full Text Available Unilateral absence of a pulmonary artery (UAPA is a rare condition with an estimated prevalence of 1 in 200,000 young adults. Most commonly, UAPA occurs in conjunction with cardiovascular abnormalities such as tetralogy of Fallot or cardiac septal defects, but it can also occur in an isolated manner. Patients with isolated UAPA can remain asymptomatic into late adulthood but usually report symptoms such as dyspnea or chest pain or suffer from hemoptysis or recurrent infections. Diagnosis can be difficult due to the rarity of the condition and its nonspecific presentation. We present a case of a 60-year-old female who presented with history of chronic cough and was found to have UAPA. Typical findings on CT were discussed.

    We present a case of a 30-year-old woman diagnosed with arterial hypertension in the 25th week of pregnancy. Our search for secondary causes of arterial hypertension revealed hyperthyroid Hashimoto's thyroiditis (HT), which was treated with propilthiouracil. Three weeks after delivery, she was normotensive without medication. In the next four months, she developed hypothyroidism and treatment with L-thyroxine was started. In conclusion, in the second half of pregnancy, a hyperthyroid HT can occur - in spite of the well-known amelioration of autoimmune thyroid disorders in that period, and can be the only cause of arterial hypertension.

    Coracoid fractures are uncommon, mostly occur at the base or neck of the coracoid process (CP), and typically present with ipsilateral acromioclavicular joint (ACJ) dislocation. However, CP avulsion fractures at the coracoclavicular ligament (CCL) attachment with ACJ dislocation have not been previously reported. A 59-year-old woman receiving glucocorticoid treatment fell from bed and complained of pain in her shoulder. Radiographs revealed an ACJ dislocation with a distal clavicle fracture. Three-dimensional computed tomography (3D-CT) reconstruction showed a small bone fragment at the medial apex of the CP. She was treated conservatively and achieved a satisfactory outcome. CP avulsion fractures at the CCL attachment can occur in osteoporotic patients with ACJ dislocations. Three-dimensional computed tomography is useful for identifying this fracture type. CP avulsion fractures should be suspected in patients with ACJ dislocations and risk factors for osteoporosis or osteopenia. PMID:27493819

  19. An Unusual Aneurysm of the Main Pulmonary Artery Presenting as Acute Coronary Syndrome

    International Nuclear Information System (INIS)

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty

    2016-01-01

    Traumatic extensor dysfunction of the knee in children is a rare injury, with the majority resulting from tibial tubercle avulsion fracture or patellar sleeve fracture. We report a rare case of combined patellar avulsion fracture and tibial tubercle fracture. With open anatomic reduction, both injuries were successfully treated. While many variations of tibial tubercle fracture have been reported, the authors believe this to be the first report in the English-language literature of this particular combined injury to the knee extensor mechanism in an adolescent. Advanced imaging with computed tomography provided vital information to aid with operative planning, especially since the majority of the unossified tubercle was not seen on plain radiographs, and all fracture fragments were originally believed to be from the tibial tubercle. Computed tomography distinguished the patellar fracture from the tibial tubercle fragments, verifying preoperatively the complexity of the injury. PMID:26761925

    Precise and detailed knowledge of possible anatomical variations of the arterial pattern in the upper extremity is vital during reparative surgery in this region. Scientific literatures witnessed several reports on variant origin and branching pattern of ulnar artery. But report on looped and tortuous ulnar artery is lacking in the literature. We report here a unique case of ulnar artery having double loop at its commencement giving it an appearance of sigmoid shape and its undue tortuous course in the forearm. Such an unusual and unpredictable variation of ulnar artery is vulnerable for life threatening hemorrhage during clinical approaches. It could also lead to misinterpretation of CT scans as presence of tumours. Awareness on such exceptional anatomical discrepancy of ulnar artery is important to clinicians, neuroradiologists and radiologists in general. PMID:27504273

    Anomalies of aortic arch are a common occurrence. Such anomalies of right sided aortic arch with its various branching patterns are of clinical importance. Rarer anomalies include isolation (deficient connection) of either left subclavian artery or left common carotid artery; that is, they do not have their origin from aorta or its major branches. We present a case of an 18-year-old male who presented with gradual onset pulsatile swelling with bruit in neck on left side and was evaluated by CT brain and neck angiography. CT angiography revealed right sided aortic arch with aberrant left subclavian artery and isolated left common carotid artery. Very few cases of such an anomaly have been documented in the literature but none in an adult.

  3. Intra-arterial therapy for cardio embolic internal carotid artery terminus occlusion: The past and present status in real practice

    International Nuclear Information System (INIS)

    There is little data on the effect of intra-arterial therapy (IAT) in acute cardioembolic internal carotid artery terminus (ICAT) occlusion that has poor prognosis. We determined procedural and clinical outcomes in patients with acute cardioembolic ICAT occlusion treated with different methods of IAT. On retrospective review of our registry, patients with cardioembolic ICAT occlusion were categorized as thrombolytic-based IAT group (TLG) and thrombectomy-based IAT group (TEG) according to the primary endovascular technique. Subsequently, procedural and clinical outcomes were compared. Fifty-five patients had cardioembolic ICAT occlusion and 18 patients were assigned to TLG and 37 patients to TEG. The rate of complete reperfusion was significantly higher and the groin puncture to reperfusion time was significantly shorter in TEG than those in TLG. There was a trend towards functional outcome at 3 months in the TEG group; however, it was not statistically significant (p = 0.06). Age, baseline Albert Stroke program early CT score and puncture to reperfusion time were factors affecting unfavorable outcome at 3 months, on multivariable analysis. Thrombectomy-based IAT has advantages over thrombolytic-based IAT in terms of the reduction of groin puncture to reperfusion time and improvement of the rate of complete reperfusion

    OBJECTIVE: To sum up the treatment of brachial plexus root avulsion and the progress in functional reconstruction and rehabilitation following brachial plexus root avulsion.DATA SOURCES: A search of Medline was performed to select functional reconstruction and rehabilitation following brachial plexus injury-related English articles published between January 1990 and July 2006, with key words of "brachial plexus injury, reconstruction and rehabilitation". Meanwhile, a computer-based search of CBM was carried out to select the similar Chinese articles published between January 1998 and July 2006,with key words of "brachial plexus injury, reconstruction and rehabilitation".STUDY SELECTION: The materials were checked primarily, and the literatures of functional reconstruction and rehabilitation of brachial plexus injury were selected and the full texts were retrieved.Inclusive criteria: ① Functional reconstruction following brachial plexus injury. ② Rehabilitation method of brachial plexus injury. Exclusive criteria: Reviews, repetitive study, and Meta analytical papers.DATA EXTRACTION: Forty-six literatures about functional reconstruction following brachial plexus injury were collected, and 36 of them met the inclusive criteria.DATA SYNTHESIS: Brachial plexus injury causes the complete or incomplete palsy of muscle of upper extremity. The treatment of brachial plexus is to displace not very important nerves to the distal end of very important nerve, called nerve transfer, which is an important method to treat brachial plexus injury.Postoperative rehabilitations consist of sensory training and motor functional training. It is very important to keep the initiativeness of exercise. Besides recovering peripheral nerve continuity by operation, combined treatment and accelerating neural regeneration, active motors of cerebral cortex is also the important factor to reconstruct peripheral nerve function.CONCLUSION: Consciously and actively strengthening functional

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

    2012-01-31

    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.

  10. Present status of doctors' awareness for radiation-induced carotid artery disease in Japan

    International Nuclear Information System (INIS)

    Radiation-induced carotid artery disease (RCAD) often develops in patients who have received neck radiotherapy for the treatment of various malignant tumors. However, the doctors who ordered or performed neck radiotherapy seem to pay little attention to RCAD which may subsequently occur, and the present status of the awareness in these doctors for RCAD is unclear in Japan. Therefore, we conducted a questionnaire survey of the present status of these doctors' awareness for RCAD. A questionnaire form regarding the recognition of RCAD was sent to 368 departments of otolaryngology, oral surgery, or radiology of university hospitals in Japan. Responses to the questionnaire were received from 213 of the 368 departments of otolaryngology, oral surgery or radiology of university hospitals (response collection rate: 57.9%). One hundred and sixty-one departments (75.9%) were aware of the existence of RCAD, but only 20 departments (9.4%) conducted regular examinations for RCAD after neck radiotherapy such as ultrasound neck echography and MR angiography. Only 6.3% departments took preventive measures for RCAD such as reduction in radiation dose or administration of antiplatelets. The present survey revealed that many patients who had undergone neck radiotherapy for the treatment of malignancy did not receive proper medical attention for RCAD in Japan. Healthcare providers should be given adequate education about RCAD including its risk factors, possible preventive measures, diagnostic modalities, and treatment. Furthermore, a systematic clinical network should be established in which stroke specialists conduct proper examinations for early diagnosis of RCAD. (author)

    2011-08-01

    Full Text Available Abstract Introduction Magnetic resonance imaging of the brain in patients with corticobasal degeneration typically shows focal or asymmetric atrophy, usually maximal in the frontoparietal cortex. Many patients who are diagnosed with corticobasal degeneration using current diagnostic criteria do not have classical corticobasal degeneration pathology. Our case is remarkable for the fact that the symptoms and the characteristic magnetic resonance imaging appearance were typical for corticobasal degeneration. However, we were quite convinced that the clinical picture had a vascular etiology. Only a few cases have been reported where the presumed cause for the corticobasal syndrome was multiple brain infarctions bilaterally. Case presentation A 64-year-old Caucasian man visited a neurologist because of profound asymmetric sensory and motor disturbances. A magnetic resonance imaging scan of his brain revealed occlusion of his internal carotid artery on the left side with multiple vascular lesions in his left hemisphere and notable atrophy of mainly the left parietal and frontal cortex. Conclusion We describe a patient with corticobasal syndrome caused by multiple infarctions, probably caused by emboli of the carotid stenosis. This patient illustrates the fact that the word 'syndrome' should be preferred above 'degeneration' in the name of this disease.

    2011-01-01

    Full Text Available Avulsion fractures of the anterior inferior iliac spine are rare injuries of the pelvic ring and occur during sports activities. Hereby is presented a case of a 22-year-old professional football player who was diagnosed to have an avulsion fracture of the anterior inferior iliac spine on the right side four months after the initial injury and he was treated surgically with the excision of the avulsed fragment. The football player recovered completely and returned to his usual sports activities. Two years later, due to the pain in the hip an x-ray and MR image were made, which established the existence of crescent formation, a heterotopic bone, in the area of the anterior inferior iliac spine, which was surgically removed. Physical and medical therapy was conducted and after four months, the professional athlete was back playing football. Two years after the surgical excision of heterotopic ossification, the patient was completely asymptomatic with the same ROM without any thigh muscle hypotrophy, although isokinetic muscle testing did show some weakness of the thigh extensor muscles. An x-ray did not show any signs of heterotopic ossification.

  13. Acute avulsion fractures of the pelvis in adolescent competitive athletes: prevalence, location and sports distribution of 203 cases collected

    International Nuclear Information System (INIS)

    Objective. To describe the prevalence, location and sports distribution of pelvic avulsion fractures in adolescent competitive athletes. Design and patients. One thousand two hundred and thirty-eight radiographs of the pelvis taken for focal traumatic symptoms in athletes with an age range of 11-35 years over a period of 22 years were reviewed. Results. One hundred and ninety-eight adolescent athletes were affected by 203 avulsion fractures of the pelvic apophyses (five cases presented multiple locations). The localisation was the ischial tuberosity (IT) in 109 cases, anterior inferior iliac spine (AIIS) in 45 cases, anterior superior iliac spine (ASIS) in 39 cases, superior corner of pubic symphysis (SCPS) in 7 cases and iliac crest (IC) in 3 cases. Soccer (74 cases) and gymnastics (55 cases) were the sports with the highest number of avulsion fractures documented. Conclusions. Apophyseal avulsion fractures of the pelvis in adolescent competitive athletes are most common in soccer and gymnastics. The lesions are usually the consequence of sudden and forceful muscle-tendon contractions during sport activities. Plain radiographs, are determinant for the diagnosis. (orig.)

  15. Humeral avulsion of the anterior shoulder stabilizing structures after anterior shoulder dislocation: demonstration by MRI and MR arthrography

    International Nuclear Information System (INIS)

    Objective. To demonstrate the MRI findings of an anterior shoulder capsular avulsion from the humerus, with or without subscapularis rupture, after anterior dislocation or severe abduction external rotation injury. Design and patients. We retrospectively reviewed the MRI and MR arthrographic examinations of seven patients who were identified at surgery with avulsion of the anterior shoulder stabilizers from the humerus. MRI was correlated with clinical history and surgical results. Results. MRI findings included: inhomogeneity or frank disruption of the anterior capsule at the humeral insertion (all), fluid intensity anterior to the shoulder (six patients), tear of the subscapularis tendon (six patients), dislocation of the biceps tendon (four patients), and a Hill-Sachs deformity (four patients). MR arthrography additionally found extravasation of contrast through the capsular defect (two patients). Conclusions. Our findings suggest that MRI is helpful for diagnosing humeral avulsion of the anterior glenohumeral capsule, especially when a tear of the subscapularis tendon insertion is present. MR arthrography may be of benefit for diagnosing capsular avulsion without associated subscapularis tendon abnormality. (orig.). With 4 figs

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

    Directory of Open Access Journals (Sweden)

    Lyudmila Andreevna Kalashnikova

    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.

  18. Unilateral central retinal artery occlusion as the sole presenting sign of Susac syndrome in a young man: case report

    Directory of Open Access Journals (Sweden)

    Samira Luiza dos Apóstolos-Pereira

    2013-06-01

    Full Text Available We report the case of a 24-year-old man presenting with sudden visual loss in the left eye from a central retinal artery occlusion. An extensive clinical investigation revealed no etiology. Three weeks later, however, the patient developed hearing loss followed by encephalopathy and multiple branch retinal artery occlusions in the right eye. Fluorescein angiography confirmed retinal vascular occlusions with no sign of vasculitis. The neurological examination revealed a diffuse encephalopathy while the MRI scan disclosed several small areas of infarcts in the brain. Bilateral sensorineural hearing loss was confirmed on audiometry. The patient was diagnosed with Susac syndrome and treated with methylprednisolone and cyclophosphamide, resulting in slight improvement and stabilization. This case shows that Susac syndrome may be diagnosed late due to the absence at onset of one or more of the symptoms of the classic triad (encephalopathy, multiple branch retinal artery occlusions and hearing loss. This case also serves to emphasize that Susac syndrome should be considered in the differential diagnosis of central retinal artery occlusion, even in apparently healthy young men.

    Full Text Available Abstract Introduction A primary hydatid cyst of the adrenal gland is still an exceptional localization. The adrenal gland is an uncommon site even in Morocco, where echinococcal disease is endemic. Case presentation We report the case of a 64-year-old Moroccan man who presented with the unusual symptom of arterial hypertension associated with left flank pain. Computed tomography showed a cystic mass of his left adrenal gland with daughter cysts filing the lesion (Type III. Despite his negative serology tests, the diagnosis of a hydatid cyst was confirmed on surgical examination. Our patient underwent surgical excision of his left adrenal gland with normalization of blood pressure. No recurrence has occurred after 36 months of follow-up. Conclusion There are two remarkable characteristics of this case report; the first is the unusual location of the cyst, the second is the association of an adrenal hydatid cyst with arterial hypertension, which has rarely been reported in the literature.

    2015-04-01

    An avulsion fracture of the tibial tubercle is an uncommon injury, comprising less than 1% of all physeal injuries. The occurrence of such injuries bilaterally is even rarer. We report a case of bilateral atraumatic tibial tubercle avulsion fractures and its presentation, mechanism of injury, surgical management, post-operative rehabilitation and implications for clinical practice. A 17-year-old healthy male presented to the emergency department with severe pain on the anterior aspect of both knees and was unable to walk, having been brought in by ambulance after hearing a crack whilst jogging. On examination, there was significant swelling of both knees which were held in extension. On both sides there was a prominent deformity on the region of the tibial tubercle with a palpable gap, although no open skin wound. He was unable to actively move either knee joint. No neurovascular deficit was present. Plain radiographs revealed bilateral tibial tubercle avulsion fractures. Gentle manipulation was performed in the emergency department to the fragments in order to remove the tension from the skin. The fragments were reduced and fixed surgically with 4mm cannulated screws in an anterior to posterior direction. Both limbs were placed in temporary casts in 20 degrees of flexion. Postoperatively, the patient was kept non-weight bearing for four weeks then placed into a range of motion brace and movement commenced. Full weight bearing was permitted at the one month stage and he was advised to avoid any sporting activity until the 8 week stage and contact sports until the 10 week stage. Full movement of both joints was regained and the patient returned to full sporting activity in the absence of symptoms. This case emphasises the need for a high degree of vigilance when faced with such a presentation and a low threshold for further investigation and surgical intervention. PMID:25638599

  2. Radicular avulsion resulting from spinal injury: Assessment of diagnostic modalities

    International Nuclear Information System (INIS)

    The diagnostic utility of imaging techniques in injuries to the intramedullary and subarachnoid portions of the brachial plexus, with possibly complete avulsion of one or more nerve roots from the spinal cord and extramedullary meningocoele was compared in 18 patients studied by unenhanced computed tomography (CT), cervical myelography, myelographic CT (MCT) and magnetic resonance imaging (MRI). Emphasis was placed on the lesions of the subarachnoid roots. CM was the only diagnostic modality to show avulsion of 18 nerve roots and their levels in 8 patients (100% = gold standard), and to verify 2 incomplete avulsions. MCT reliably revealed 8 of 18 (45%) and MRI 1 out of 18 (6%) avulsions. Myelography with MCT showed intact subarachnoid nerve roots in 10 additional patients. MRI and MCT (16 out of 16 = 100%) were superior to myelography (14/16 = 88%) for demonstrating 16 traumatic meningocoeles in 8 patients; follow-up MRI (6-24 months) showed no increase in their size. We recommend a subsequent CT to role out fracture to the spinal column; MRI should provide significant information concerning oedema or haemorrhage in the spinal cord. Myelography with segmental MCT is performed to differentiate pre- from post-ganglionic lesions, data which are essential for deciding whether exploration of the plexus or a motor substitution operation is indicated.

    Seferi, Arsen; Alimehmeti, Ridvan; Pajaj, Ermira; Vyshka, Gentian

    2016-01-01

    Background: Superficial temporal artery (STA) pseudoaneurysms have been reported in the literature since the mid of seventeenth century from Bartholin, however, there is an increasing number of cases, suggesting a diversity of etiological factors. Among these, traumatic events, even of an iatrogenic nature, have been identified as causative factors for nonspontaneous STA pseudoaneurysms. Regional pain and tenderness, troublesome pulsations of the mass, cosmetic concerns as well as the risk of bleeding warrant a thorough evaluation and a definite interventional approach to the condition. Case Description: A 21-year-old Caucasian male searched medical advice for a growing, tender, and pulsatile mass on his right temple, with isolated and short episodes of lancinating sensations, after sustaining a blunt trauma following a hit with a stick half a year before the admission. Enhanced cranial computed tomography and angiography confirmed the diagnosis of an STA pseudoaneurysm. A direct percutaneous aspiration, as well as ultrasonography, was performed prior to the neurosurgical intervention, with the complete removal of the mass. Conclusions: STA pseudoaneurysms require a careful evaluation and a conclusive approach in order to avoid the risk of a growing mass and other nonremote complications such as bone erosions and bleeding. Different treatment options are available, including endovascular obliteration and embolization, however, surgical removal after ligation of the afferent and efferent segments of the vessel seem to be highly effective.

    2015-07-01

    The maxillofacial region is one of the most injury-prone areas during road traffic accidents, personal violence, falls and sports. Maxillofacial trauma can lead to breakage or avulsion of upper anterior teeth, which may cause significant aesthetic and functional problems. There are many treatment options available for rehabilitation including removable partial dentures, fixed partial dentures, crown and bridges and implant-supported prostheses. Herein, two cases are presented where implant placement was done for upper anterior teeth, which were traumatized or avulsed following maxillofacial trauma. Both patients demonstrated a history of maxillofacial trauma and had undergone open reduction and internal fixation. The first patient had a severe maxillary alveolar defect treated via autogenous bone grafting and a six-month period was given for proper integration of the bone graft. The second patient was a smoker with very poor oral hygiene and a deep bite. Thus, implant placement was not initially justified. PMID:26877745

    Abstract Avulsion fractures of the posterior cruciate ligament (PCL) are uncommon. On the basis of the site of damage of the PCL, hyperflexion, pretibial trauma, and hyperextension are proposed as mechanisms of PCL injuries. On the other hand, avulsion fractures of the tibial condyle are also rare. We report a PCL-mediated avulsion fracture of the lateral tibial condyle along with the tibial insertion of the PCL by extension-distraction force on the knee that has not been previously described...

    Full Text Available Objective: To assess the knowledge on reimplant-avulsion of Physical Education Teachers’ in the city of Caruaru (PE. Methods: The study was carried on in the city of Caruaru, Pernambuco (BR, and the participants were 79 professionals who were interviewed through a standard questionnaire containing 11 questions related to dental avulsion as well as to the procedures to be followed in such cases.  Results: Only 20.3% of teachers knew what dental traumas are, but none of them had studied the subject during their undergraduate course.  It was explained to participants what a dental avulsion was and 44.3% of them answered that they had already seen this kind of trauma in their classes.  All professionals said they would give children a handkerchief or a towel for them to bite in order to control bleeding. 19% of the participants would not know what to do and 81% would wash the tooth in water. Most of them (86.1% recognized the importance of an immediate treatment; all of them said they would wrap the tooth in a paper napkin until the child was assisted; and 26.6% said they would suggest an analgesic for the pain.  Conclusion: Teachers did not show any knowledge of the emergency procedures that should be taken in a case of dental avulsion. The inclusion of such procedures in the programs of physical education courses and the availability of preventive educational programs is needed in order to increase the chances of a successful dental reimplant.

    The present study investigates the effects of xenotransplantation of Adipose Tissue Mesenchymal Stem Cells (AT-MSCs) in animals after ventral root avulsion. AT-MSC has similar characteristics to bone marrow mesenchymal stem cells (BM-MSCs), such as immunomodulatory properties and expression of neurotrophic factors. In this study, Lewis rats were submitted to surgery for unilateral avulsion of the lumbar ventral roots and received 5 × 10(5) AT-MSCs via the lateral funiculus. Two weeks after cell administration, the animals were sacrificed and the moto neurons, T lymphocytes and cell defense nervous system were analyzed. An increased neuronal survival and partial preservation of synaptophysin-positive nerve terminals, related to GDNF and BDNF expression of AT-MSCs, and reduction of pro-inflammatory reaction were observed. In conclusion, AT-MSCs prevent second phase neuronal injury, since they suppressed lymphocyte, astroglia and microglia effects, which finally contributed to rat motor-neuron survival and synaptic stability of the lesioned motor-neuron. Moreover, the survival of the injected AT- MSCs lasted for at least 14 days. These results indicate that neuronal survival after lesion, followed by mesenchymal stem cell (MSC) administration, might occur through cytokine release and immunomodulation, thus suggesting that AT-MSCs are promising cells for the therapy of neuronal lesions.

    Full Text Available Avulsion fractures of tibial intercondylar eminence is a rare injury mainly affecting the pediatric population between 8 to 14 and is even rarer in adults with very few cases reported in literature. It occurs with high energy trauma in adults and may be associated with knee dislocation and neurovascular injuries. A 30 yr old male presented with a painful swollen left knee , limite d knee motion , and difficulty with weight bearing after a history of fall from motorcycle. Imaging revealed Type 3 Meyers and McKeever tibial spine avulsion of both ACL and PCL. A two staged surgical procedure was performed : (a Arthroscopic reduction and fixation with headed cannulated sc r ew of ACL tibial fragment; (b ORIF with headed cannulated screw of PCL tibial fragment via posterior approach to knee. Good functional outcome and early mobilization was achieved. Diagnostic arthroscopic helps to evaluat e the condition of the cruciate ligaments as well as fracture bed. Simultaneously fixation of ACL fragment with cannulated screw can be done , which is a simpler procedure to suture fixation. ORIF of PCL fragment in a staged manner has helped to address the injury in a detailed manner achieving goal of anatomical reduction and early mobilization.

    Dental avulsion is the most severe type of traumatic tooth injuries because it causes damage to several structures and results in the complete displacement of the tooth from its socket in the alveolar bone. The ideal situation is to replant an exarticulated tooth immediately after avulsion because the extraoral time is a determinant factor for treatment success and for a good prognosis. However, it is not always possible. The success of replantation depends on a number of factors that may contribute to accelerate or minimize the occurrence of root resorption or ankylosis, among which is the type and characteristics of the medium used for temporary storage during the time elapsed between avulsion and replantation. Maintaining the tooth in an adequate wet medium that can preserve, as longer as possible, the vitality of the periodontal ligament cells that remain on root surface is the key to success of replantation. Recent research has led to the development of storage media that produce conditions that closely resemble the original socket environment, with adequate osmolality (cell pressure), pH, nutritional metabolites and glucose, and thus create the best possible conditions for storage. Although these storage media can now be purchased in the form of retail products, the most common scenario is that such a product will not be readily available at the moment of the accident This paper reviews the literature on the different storage media that have been investigated for avulsed teeth based on full-length papers retrieved from PubMed/Medline, Lilacs, BBO and SciELO electronic databases using the key words 'storage medium', 'transportation medium', 'avulsion', 'tooth avulsion', 'replantation', 'tooth replantation', 'milk' and 'propolis'. After application of inclusion and exclusion criteria, 39 papers were selected and critically reviewed with respect to the characteristics, efficacy and ease of access of the storage medium.

    Background: There are limited data on outcomes of patients with previous coronary artery bypass grafting (CABG) presenting acutely as ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PPCI). Objectives: To compare outcomes in STEMI patients undergoing PPCI with or without previous CABG surgery. Methods: An all-comer single-centre observational registry from a cardiothoracic centre in UK. All consecutive patients presenting for PPCI between 2007 and 2012 were included. Electronic records were used to extract relevant information. Mortality data were obtained from the Office of National Statistics. Overall median follow-up period was 1.7 years (intraquartile range 0.9-2.5). Results: Complete data were available for 2133 (97%) patients. 47-patients had previous history of CABG. Out of these, the infarct related artery (IRA) was native vessel in 22 and graft in 25 patients. Post re-vascularization TIMI flow was inferior in CABG cohort (presenting with STEMI to PPCI service with history of CABG are less likely to achieve acute reperfusion and have worse angiographic outcomes. Post PPCI, the prior CABG patients do not seem to have worse shortterm and long-term prognosis. PMID:27006712

    We describe the case of a 72-year-old woman who displayed massive multiple intramural gas collections of the bladder wall as an incidental finding on CT. The patient presented with critical ischemia of the left leg caused by paradoxical arterial embolism, raised corpuscular sedimentation rate, anemia by gastrointestinal blood loss, hypoproteinemia, diarrhea, malabsorption, and exudative enteropathia caused by mycobacterial ileocolitis. The patient had no dysuria and there was no evidence of diabetes. The intramural gas collections of the bladder wall, as shown by CT, were compatible with emphysematous cystitis. Urine samples proved infection by a multi-resistant strain of E. coli. Emphysematous cystitis is a rare form of bladder infection that can be diagnosed by plain-film radiograms or CT. (orig.)

  9. Idiopathic infantile arterial calcification in a 12-year-old girl presenting as chronic mesenteric ischemia: imaging findings and angioplasty results

    International Nuclear Information System (INIS)

    We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

    Full Text Available Summary: This report describes favorable outcomes in 9 patients with skin avulsion injuries of the extremities who underwent full-thickness skin grafting and basic fibroblast growth factor (bFGF application. Following removal of contaminated subcutaneous fat tissue on the inside of skin, the avulsed skin was processed into a full-thickness skin graft, with as much of the skin used as possible irrespective of damage. Several drainage holes (5–10 mm in diameter were made on the graft for drainage from the graft bed and to prevent seroma and hematoma formation. Genetically recombinant human bFGF was sprayed at a dose of 1 μg/cm2 onto the graft bed, which was then covered with the graft and sutured. Pressure immobilization with ointment gauzes and elastic bandages was administered for 1 week postoperatively, and the surface of the skin grafts that did not take was scraped away, preserving the revascularized dermal component on the debrided raw surface as much as possible. bFGF was sprayed again onto the debrided surface to promote epithelialization. Wound closure was achieved in all cases with conservative therapy. The surgical procedure was effective in preventing postoperative ulcer formation and scar contracture and resulted in wound healing with the formation of good-quality, flexible scars.

    Full Text Available Abstract Introduction We describe the case of a 79-year-old Caucasian Italian woman with a transient basilar occlusion monitored by transcranial Doppler, with subsequent recanalization and clinical shrinking deficit. This is the first case of transient basilar occlusive disease diagnosed and monitored by transcranial Doppler. This case is important and needs to be reported because transient basilar occlusion may be easily diagnosed if transcranial Doppler is performed. Case presentation A 79-year-old woman affected by chronic atrial fibrillation and not treated with oral anticoagulants, cardioverted to sinus rhythm during a gastric endoscopy. She then showed a sudden-onset loss of consciousness, horizontal and vertical gaze palsy, tetraparesis and bilateral miosis and coma. Two hours later, the symptoms resolved quickly, leaving no residual neurologic deficits. Transcranial Doppler examination showed a dampened flow in the basilar artery in the emergency examination and a restored flow when the symptoms resolved. Conclusion This is the first case of transient basilar occlusive disease diagnosed and monitored by transcranial Doppler. We believe that transcranial Doppler should be performed in all cases of unexplained acute loss of consciousness, in particular, if associated with signs of brainstem dysfunctions.

    Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in rats. After these models were established, we administered apomorphine (via a sub-cutaneous injection in the neck) to observe changes in erectile function. Rats subjected to simple brachial plexus root avulsion or those subjected to brachial plexus root avulsion combined with spinal cord injury had signiifcantly fewer erections than those subjected to the sham operation. Expression of neuronal nitric oxide synthase did not change in brachial plexus root avulsion rats. However, neuronal nitric oxide synthase expression was signiifcantly decreased in brachial plexus root avulsion + spinal cord injury rats. These ifndings suggest that a decrease in neuronal nitric oxide synthase expression in the penis may play a role in erectile dysfunction caused by the combi-nation of brachial plexus root avulsion and spinal cord injury.

    We report an unusual case of a pseudoaneurysm of the superior gluteal artery as a complication of bone marrow biopsy. A 51-year-old man presented with sciatic pain and foot drop after undergoing bone marrow biopsy and was initially diagnosed as having degenerative disc disease based on his past medical history. Pelvic magnetic resonance imaging (MRI) revealed a large heterogeneous mass suggestive of a neurogenic tumor, but pulsatile blood was instead encountered during computed tomography (CT)-guided needle biopsy. Subsequent workup established the diagnosis of a superior gluteal artery pseudoaneurysm, which was treated with coil embolization, followed by surgical evacuation of the hematoma, which relieved his sciatic pain. However, the patient continues to have a persistent foot drop. Gluteal artery pseudoaneurysms are exceedingly uncommon but should be considered in the workup of a patient with gluteal pain or sciatic nerve palsy following trauma or medical procedures in the gluteal region.

    BACKGROUND: Avulsion fractures of the tibial tubercle are an unusual injury pattern generally occurring in the adolescent male during sporting activities. Bilateral simultaneous fractures are extremely rare. They are often associated with other underlying orthopaedic pathology. AIMS: We present a case of bilateral tibial tubercle avulsions occurring in a 15 year-old male hurler. We describe the management and necessary investigations required for this type of trauma and present a literature review on this rarely encountered injury. CONCLUSION: Although this type of atypical fracture pattern is associated with high energy trauma and other underlying pathology, we have shown that once treated, the patient can expect to make a prompt return to sporting activities with no significant long-term functional deficit.

    INTRODUCTION To investigate the feasibility and clinical efficacy of using a toothed plate and hollow lag screw in the surgical treatment of posterior cruciate ligament (PCL) avulsion fractures of the tibia. METHODS A total of 21 patients were treated with open reduction and internal fixation using a toothed plate and hollow lag screw, through a posteromedial approach using an inverted L-shaped incision. The patients were allowed appropriate functional exercises, including knee flexion and extension, after removal of the plaster at postoperative weeks 3–6. The follow-up period was between six months and two years. RESULTS This was a retrospective study of patients with PCL avulsion fractures of the tibia caused by road traffic accidents (n = 9), sports-related injuries (n = 6), falls (n = 5) and machinery-related injuries (n = 1). 20 patients presented with fresh fractures and one with an old fracture. The patients (13 men, eight women) had a mean age of 41.5 (range 19–72) years. Anatomical reduction of the fracture and satisfactory fixation were achieved in all 21 patients. Bony union was achieved in all patients at 8–12 weeks after surgery. Six months after surgery, knee flexion was 121.9° ± 10.4° and extension was 0°. According to the Lysholm Knee Scoring Scale, 19 patients were rated as ‘excellent’ and two as ‘good’. CONCLUSION The use of a toothed plate and hollow lag screw could be a simple and reliable approach for PCL avulsion fractures of the tibia. Patients achieved good knee function after surgery.

    It is possible to replant an incisor tooth completely avulsed after trauma in adults. These cases are relatively frequent among athletes. It is essential to conserve the tooth in saline solution. The time before replantation must be as short as possible. The simple technique described here, which requires a minimum of material and no dental chair, makes it possible to replant an avulsed incisor with a good success rate. PMID:23803559

    Avulsion injuries of the adductor longus muscle tendon are rare and a challenge to manage especially in athletes. There has been little published literature on the outcome of conservative and operative treatment for these injuries. We report the first case of an acute adductor longus avulsion injury which was surgically repaired in a professional equestrian rider. Return to full preinjury function was achieved at 3 months with surgical repair using 3 suture anchors.

    The development of acute myeloid leukemia has been attributed to various factors, including hereditary, radiation, drugs, and certain occupational exposures. The association between malignancy and venous thromboembolism events is well established. Here, we present a case of a 70-year-old Indian man who had presented with arterial and venous thrombosis, and the patient was later diagnosed with acute promyelocytic leukemia (APL). In our case, the patient presented with right lower limb deep venous thrombosis and pulmonary thromboembolism four months prior to the diagnosis of APL. Although thromboembolic event subsequent to the diagnosis of malignancy, and especially during the chemotherapy has been widely reported, this prior presentation with simultaneous occurrence of both venous and arterial thromboembolism has rarely been reported. We take this opportunity to state the significance of a complete medical evaluation in cases of recurrent or unusual thrombotic events. PMID:26949347

    The Huanghe River is known for high suspended sediment concentration and resultant heavy sedimentation and frequent channel-shifting among major rivers in the world. This plain coastal river is the main contributor of terrestrial sediment to the Bohai Sea and the Yellow Sea. Since 1855, there have been 11 major avulsions (versus 4 avulsions on the Mississippi River during the Holocene) on the lower reach with an recurrence interval of ~10 years, developing individual lobes that build up the modern Huanghe River delta. We summarize the main features of riverbed evolution on the delta with a database of measured data. The observed avulsions on the delta often occurred along a persistent spatial node, whose distance from the shoreline scales with the computed backwater length. In order to explain the avulsion locations on the delta, and meanwhile to test the viewpoint of river backwater controls on avulsion locations on deltas, we simulate the long profile evolution of the riverbed on the delta considering river discharge, river plume spreading, land subsidence and sea level rise, with a 1D fluvial morphodynamic model. The main results from the numerical simulations provide insights into how the long profile of the river on the delta evolves at the time scales of flood events and avulsions.

    Myocardial bridging has been observed to provoke symptoms in association with strenuous physical activity and hypertrophic cardiomyopathy; more recently, bridging has been thought to cause coronary vasospasm. Autopsy findings tend to reveal higher incidences of bridging than do angiography series, but both show an almost uniform predilection for left coronary artery distribution—especially in regard to bridging that manifests itself clinically. Herein, we report an unusual case of myocardial ...

    Dorsal root avulsion results in permanent impairment of sensory functions due to disconnection between the peripheral and central nervous system. Improved strategies are therefore needed to reconnect injured sensory neurons with their spinal cord targets in order to achieve functional repair after brachial and lumbosacral plexus avulsion injuries. Here, we show that sensory functions can be restored in the adult mouse if avulsed sensory fibers are bridged with the spinal cord by human neural ...

    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.

  14. A Study of the anthropometric and demographical profile of patients presenting with coronary artery disease at Mayo Hospital, Lahore

    International Nuclear Information System (INIS)

    Coronary artery disease (CAD) is very common in the South Asian sub-continent, yet there is relatively little published research available from these countries. Although we have a very active Cardiology Department in Mayo Hospital, Lahore, there is a parallel need for documentation of the data generated and its analysis for research and publication. This study was carried out to gain an insight into the nature of the risk factors and presentation of CAD in patients coming to our setup. Objectives: The objective was to study the relation of CAD with anthropometric (BMI, waist circumference, waist . to . height ratio) and demographical (age and gender) factors. Methodology: This study was carried out in the Department of Cardiology, Mayo Hospital, Lahore, for a duration of 17 months. We collected the required information (such as name, gender, and family history, demographical data and anthropometric measurements) on a prescribed proforma, managed and then analyzed accordingly. Results: In this study there were 302 (80.5%) males and 73 (19.5%) females. The number of males was significantly higher (p-value 0.000), but the frequency of different diagnoses was statistically the same in both males and females, i.e. p-value = 0.062. According to the WHO recommended criteria for the BMI of South Asian populations, there were 9(2.4%) people who were under weight, among these 7 (77.8%) were males and 2 (22.2%) were females patients. Out of 302 males, 7(2.3%) were under weight, 36 (11.9%) were of normal weight, 115 (38.1%) were overweight and the rest of 144 (47.7%) were obese. Among 73 females, 2 (2.7%) were under weight, 8 (11%) had normal weight, 15 (20.5%) were overweight and 48 (65.8%) were obese. The proportion of obesity was more in females in this study, p-value (0.000). The mean waist circumference of all patients was 95.57 +- 17.14 cm with a range of 53 - 190 cm. The waist circumference was statistically higher in males than females, p-value = 0.000. In 7 under

    Full Text Available As was the case at the conference, "Humanities professions in the knowledge society", the Director of Humanities and Philology Studies at the UOC, Isidor Marí, presents this Dossier, and the subsequent virtual debate, with the aim of gaining useful conclusions, with specific repercussions on the organisation of the degree studies and its professional projection, especially at this time, which requires study plans to be redesigned in line with the Bologna process. In the author's opinion, we can only make the right operative decisions when we are able to understand the transformations taking place in the humanistic culture framed by the knowledge society, and to do so, debate has to be opened in which students, graduates, academics, researchers, professionals and analysts can all take part.In this article, Isidor Marí analyses the tensions and contradictions that arise when attempts are made to relate the concepts of the professional world, Humanities and the knowledge society. Firstly, neither are Humanities a profession nor the study of Humanities seen by students or society to be adaptable to the definition of professional profiles. However, this highlights an important paradox, as the culture economy, (and, thus, occupations in the cultural sector, is growing increasingly throughout western societies. Likewise, in terms of the relationship between Humanities and the knowledge society, the author describes and analyses how there currently coexist voices foreseeing the worst alongside those that see information and communications technologies opening the way for an enormously positive transformation in human civilisation and a new cultural era.

    We report a case of Rathke's cleft cyst associated with anterior communicating artery aneurysm. The patient was 60-year-old woman who developed visual disturbance two months before admission to our hospital. Visual acuity on the right was 0.06 and on the left was 0.08. The visual fields showed a complete temporal hemianopsia on the left eye and an incomplete temporal hemianopsia of the right eye with a central defect of the temporal visual field. CT and MR imagings showed an intra- and suprasellar mass lesion with no enhancement. Angiography showed bilateral A1 elevations and anterior communicating artery aneurysm. The operation was performed through interhemispheric approach. Suprasellar cystic mass compressed upward the optic nerves and chiasm, and aneurysmal dome stuck in the central region of chiasm. This anatomical disorders affected to the optic chiasm resulted in a rare visual field defect. Neck clipping of aneurysm and opening of the cyst were performed. A diagnosis of Rathke's cleft cyst was made. Following surgery, her visual fields resolved but she suffered from diabetes insipidus. PMID:8672308

  1. Intracranial carotid artery calcification on head CT and its association with ischemic changes on brain MRI in patients presenting with stroke-like symptoms: retrospective analysis

    International Nuclear Information System (INIS)

    Our purpose was to study the association between the intracranial arterial calcifications observed on head CT and brain infarcts demonstrated by MRI in patients presenting with acute stroke symptoms. Institutional review board approval was obtained for this retrospective study which included 65 consecutive patients presenting acutely who had both head CT and MRI. Arterial calcifications of the vertebrobasilar system and the intracranial cavernous carotid arteries (intracranial carotid artery calcification, ICAC) were assigned a number (1 to 4) in the bone window images from CT scans. These four groups were then combined into high calcium (grades 3 and 4) and low calcium (grades 1 and 2) subgroups. Brain MRI was independently evaluated to identify acute and chronic large-vessel infarcts (LVI) and small-vessel infarcts (SVI). The relationship between ICAC and infarcts was evaluated before and after adjusting for demographics and cardiovascular risk factors. Statistical analysis could not be performed for the vertebrobasilar system due to an insufficient number of patients in the high calcium group. Of the 65 patients, 46 (71%) had a high ICAC grade on head CT. They were older and had a higher prevalence of cardiovascular risk factors. Acute SVI (P = 0.006), chronic SVI (P = 0.006) and acute LVI (P 0.04) were associated with a high ICAC grade. After adjustment for age and other risk factors, only acute SVI was associated with a high ICAC grade (P = 0.002). Although age emerged as the most important determinant of ischemic cerebral changes, there were rather complex interactions among multiple risk factors with different infarct types. A high ICAC grade demonstrated a correlation with acute SVI in our patients independent of these risk factors. (orig.)

    The purpose of this study was to investigate the effectiveness of shoulder function restoration by dual nerve transfers, spinal accessory nerve to the suprascapular nerve and 2 intercostal nerves to the anterior branch of the axillary nerve, in patients with shoulder paralysis that resulted from brachial plexus avulsion injury. It was a retrospective analysis to assess the impact of a variety of factors on reanimation of shoulder functions with dual nerve transfers. A total of 19 patients were included in this study. Most of these patients sustained avulsions of C5, C6, and C7 nerve roots (16 patients). Three of them had avulsions of C5 and C6 roots only. Through a posterior approach, direct coaptation of the intercostal nerves and the anterior branch of the axillary nerve was performed, along with accessory nerve transfer to the suprascapular nerve. Satisfactory shoulder function recovery (93.83° of shoulder abduction and 54.00° of external rotation on average) was achieved after a 62-month follow-up. This dual nerve transfer procedure provided us with a reliable and effective method for shoulder function reconstruction after brachial plexus root avulsion, especially C5/C6/C7 avulsion. The level of evidence is therapeutic IV. PMID:26835823

    Full Text Available Traumatic dental injuries (TDIs frequently occur in society and may occur at home. The ultimate prognosis of an avulsed tooth occurring in a child may depend on the parents’ knowledge of appropriate emergency measures. Therefore this study aimed at evaluating the knowledge level of a sample of Egyptian parents in the management of a case of tooth avulsion in a child. A total of 985 parents attending a Pediatric Dental Clinic formed the sample of the study. A questionnaire comprising 13 questions in simple Arabic language was used. The parents were categorized into two groups according to their education level. The tabulated data were statistically analyzed using the Chi-square test. Markedly low knowledge levels were noted in both groups. This was evidenced in replanting the avulsed primary teeth, brushing and using antiseptics to clean the roots, holding the root instead of the crown, dry storage of the avulsed permanent teeth, and neglect over time from most of the parents. However, 24.3% of group 1 and 15.6% of group 2 chose milk as a transport medium. Therefore, educational programs would be necessary to improve awareness of the immediate management of avulsed teeth.

    Land loss in the Mississippi River Delta caused by subsidence and erosion has resulted in habitat loss, interference with human activities, and increased exposure of New Orleans and other settled areas to storm surge risks. Prior to dam and levee building and oil and gas production in the 20th century, the long term rates of land building roughly balanced land loss through subsidence. Now, however, sediment is being deposited at dramatically lower rates in shallow areas in and adjacent to the Delta, with much of the remaining sediment borne by the Mississippi being lost to the deep areas of the Gulf of Mexico. A few projects have been built in order to divert sediment from the river to areas where land can be built, and many more are under consideration as part of State of Louisiana and Federal planning processes. Most are small scale, although there have been some proposals for large engineered avulsions that would divert a significant fraction of the remaining available sediment (W. Kim, et al. 2009, EOS). However, there is debate over whether small or large diversions are the economically optimally and socially most acceptable size of such land building projects. From an economic point of view, the optimal size involves tradeoffs between scale economies in civil work construction, the relationship between depth of diversion and sediment concentration in river water, effects on navigation, and possible diminishing returns to land building at a single location as the edge of built land progresses into deeper waters. Because land building efforts could potentially involve billions of dollars of investment, it is important to gain as much benefit as possible from those expenditures. We present the result of a general analysis of scale economies in land building from engineered avulsions. The analysis addresses the question: how many projects of what size should be built at what time in order to maximize the amount of land built by a particular time? The analysis

    River avulsions are important processes in the spatial evolution of river systems in tectonically active sedimentary basins as they govern large-scale patterns of sediment routing. However, the pattern and timing of avulsions in large river systems are poorly documented and not well understood. Here we document late Quaternary paleo-river channel changes in the Indo-Gangetic basin of northwest India. Using a combination of satellite remote sensing and detailed sediment coring, we analyse the large-scale planform geometry, and detailed sedimentary and stratigraphic nature of a major fluvial sedimentary deposit in the shallow subsurface. This sediment body records aggradation of multiple fluvial channel fills. Satellite remote sensing analysis indicates the trace of the buried channel complex and demonstrates that it exists in region of the Himalayan foreland where no major rivers are currently present. Thus it records the former drainage pathway of a major river, which has since been diverted. We use optically stimulated luminescence dating techniques to develop an age model for the stratigraphic succession and hence constrain the timing of river channel existence and diversion. Provenance analysis based on U-Pb dating of detrital zircons and detrital mica Ar-Ar ages indicate sediment sources in the Higher Himalayan Crystalline and Lesser Himalayan Crystalline Series indicating that this paleo-river channel system formed a major perennial river derived from the main body of the Himalaya. Specifically we are able to fingerprint bedrock sources in the catchment of the present-day Sutlej river indicating that the paleo-fluvial system represents the former course of the Sutlej river prior to a major nodal avulsion to its present day course. Our results indicate that on geologically relatively short time-scales, we observe dramatic along strike shifts in the location of major Himalayan rivers.

    Avulsion is a condition of tooth displacement outside the socket due to the trauma. In a case of tooth avulsion case of per-manent teeth, the treatment of choice is replanting the tooth back to the socket. The main concern prior to tooth replanta-tion is to maintain the vitality of periodontal ligament (PDL) cells. The vitality of PDL cells is crucial to form new perio-dontal ligament tissue to support the teeth in order to achieve the success of replantation treatment. Therefore the tooth st...

  11. Extrusion of bone anchor suture following flexor digitorum profundus tendon avulsion injury repair.

    LENUS (Irish Health Repository)

    Tiong, William H C

    2011-09-01

    Flexor digitorum profundus (FDP) zone I tendon avulsion injury is traditionally repaired with a pullout suture technique. More recently, bone anchor sutures have been used as a viable alternative and have largely replaced areas in hand surgery where pullout suture technique was once required. To date, there have been very few complications reported related to bone anchor suture use in FDP tendon reattachment to the bone. We report a very unusual case of extrusion of bone anchor through the nailbed, 6 years after zone I FDP tendon avulsion injury repair and a brief review of literature.

    The continued growth in athletic participation among children and adults has increased the potential incidence of sports-related dental injuries. Regardless of preventive measures, damage and injury to the oral cavity can occur during participation in sports. Luxations, root fractures, bony fractures, and avulsions involving 1 or more teeth are a possibility. Many of these injuries require specific protocols for splinting of the traumatized tooth or teeth to allow the best possible outcomes. This article identifies luxation and avulsion injuries, explains the rationale for splinting, reviews guidelines for splint duration, and discusses contemporary material options available to stabilize affected permanent dentition.

    Aortic dissection is the most common fatal condition of the aorta, yet it is often missed on initial clinical presentation. Aortic dissection associated with acute coronary syndrome (ACS) is relatively rare, but if it occurs, it can be diagnostically challenging, and the condition can be fatal. Here we describe a case of aortic dissection presenting as ST-segment elevation myocardial infarction (STEMI) managed via the transradial approach. We describe the current literature on the subject.

    In the case of non-ST-segment elevation acute coronary syndromes (NSTE-ACSs), the acute use of certain antiplatelet agents is complicated by concerns about perioperative bleeding risks in patients requiring coronary artery bypass grafting (CABG) during the index hospitalization. As a result, clinicians often withhold potentially useful agents, such as clopidogrel, before determining patients' coronary anatomy. An accurate predictive model could allow for a better balance of this safety concern with the demonstrated benefits of agents such as clopidogrel. To create an accurate decision-making tool that would assess, at hospital presentation, the need for CABG in patients with NSTE-ACSs, we studied 61,974 high-risk patients with NSTE-ACS admitted to 311 CABG-capable hospitals participating in Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) from 2001 to 2003. A total of 8,395 patients (14%) underwent CABG during their initial hospital stay. A multivariate model was developed and identified 13 presenting clinical characteristics significantly associated with the likelihood of CABG (previous CABG, male gender, previous heart failure, diabetes, hyperlipidemia, renal insufficiency, ST depression and transient ST elevation, age > or = 75 years, previous percutaneous coronary intervention, family history of coronary artery disease, hypertension, trends in CABG rates, and previous stroke). This model had only modest predictive accuracy and calibration (c-index = 0.67). In conclusion, although certain presenting clinical features are associated with an increased likelihood of CABG in patients with NSTE-ACSs during the index hospitalization, it remains difficult to reliably identify, before diagnostic angiography, those who will subsequently undergo surgical revascularization.

  1. PCL tibial avulsion with an associated medial meniscal tear in a child: a case report on diagnosis and management.

    LENUS (Irish Health Repository)

    2012-02-01

    Posterior cruciate ligament (PCL) injuries from tibial avulsions are rare in the paediatric setting. One would need a high index of suspicion as clinical examination may be difficult, especially in the early period. Magnetic resonance imaging is an excellent diagnostic modality for this condition and other associated injuries within the knee. We report a rare case in which the patient had a PCL avulsion off the tibial insertion site with an associated posterior horn medial meniscal tear off the posterior capsule. He was treated through open reduction and internal fixation of the avulsed fragment with suture repair of the meniscal tear. We emphasize the importance of diagnosing and managing associated intra-articular injuries when dealing with the rare condition of PCL tibial avulsion in the paediatric setting.

    2013-01-01

    Full Text Available Avulsion of permanent teeth is most serious of all dental injuries and accounts for 1-16% of all traumatic injuries, of which maxillary incisors are most commonly involved. However, in this report a rare case of isolated avulsed immature premolar has been described. The patient had reported more than 3 hours after the trauma with a tooth stored in dry condition and soil contamination. The prognosis depends on measures taken at the place of accident or the time immediately after avulsion. Replantation is the treatment of choice, but cannot always be performed immediately. An appropriate emergency management and treatment plan is important for good prognosis. In this report stepwise management of an avulsed immature maxillary premolar with extended period of dry storage has been described followed up for a period of 2 yrs.

    2014-02-01

    Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar styloid, and avulsion of the RUL resulting in distal radioulnar joint (DRUJ) instability. Materials and Methods Twenty-nine wrists of 29 patients with intra- and extra-articular distal radius fractures/malunion who underwent reduction or a corrective osteotomy of the displaced/malunited fracture, and/or wrist arthroscopy, were assessed radiographically and arthroscopically. Radial translation, radial inclination, radial shortening, volar or dorsal tilt, and the presence of an ulnar styloid fracture with more than 4 mm of displacement were measured from the initial films. Radiocarpal arthroscopy was used to assess peripheral lesions of the TFCC, while DRUJ arthroscopy was used to assess the foveal attachment. The relationship between displacement of the distal radius or the ulnar styloid fracture and the TFCC injury, including avulsion of the RUL, was recorded. Results Univariate analysis revealed that increased radial translation, decreased radial inclination, increased radial shortening, and an ulnar styloid fragment radially displaced by more than 4 mm were significant predictors of RUL avulsion at the fovea. Volar or dorsal tilt of the radius and ulnar variance did not correlate with RUL avulsion or TFCC injuries. Multiple logistic regression analysis revealed that radial translation was an independent risk factor of foveal avulsion of the RUL. Conclusions Increased radial translation and radial shortening and decreased radial inclination of the distal fragment can be associated with a foveal avulsion of the RUL. Radial translation can be an independent risk

    Myelography has been the most popular and reliable method for evaluation of nerve root avulsion in brachial plexus injury. However, it is invasive because it requires the use of contrast medium, dural puncture and exposure to radiation. In addition, it has a fault. When a nerve rootlet is not filled with contrast medium, it is impossible to evaluate it. It has sometimes been a problem in the injury to upper roots. Recently, MRI also has been used for diagnosis of brachial plexus injury. But it was not until recently that it has had a high resolution to detect affected nerve rootlets. We have used MR myelography with high resolution for diagnosis of brachial plexus injury. The purpose of this study is to investigate the usefulness of it. MR myelography was preoperatively performed in 14 cases, consisting of 13 traumatic brachial plexus injuries and an obstetrical palsy. In them, 12 cases had root avulsion injuries and 2 cases had infraclavicular injuries. A 1.5 Tesla MR system (Philips) and a cervical coil were used. Coronal sections with 2 mm-overcontiguous thickness were obtained by heavily T2-weighted sequence fast spin echo (TR/TE=3000/450). The fat signal was suppressed by a presaturation inversion-pulse. The scanning time was about five minutes. The three-dimensional image was reconstructed by using maximum intensity projection (MIP) method. MIP images and individual coronal images were used for evaluation for root avulsion. In evaluation the shape of a nerve sleeve and nerve rootlets was compared on both sides. The abnormal shape of a nerve sleeve or the defect of nerve rootlets was diagnosed as root avulsion. The brachial plexus lesions were exposed operatively and examined with electrophysiologic methods (SEP and/or ESCP) in all cases. Operative findings were compared with MR myelography. Twenty-four roots had been diagnosed as normal and 46 roots had been diagnosed as root avulsion with MR myelography preoperatively. In the former only one root was

    To determine the presence of cruciate ligament tears following avulsion injuries involving the ACL and PCL, and to correlate the findings with those of surgery. Between March 1997 and May 2002, avulsion injury involving the ACL and PCL was diagnosed in 19 patients. Ten of these [8 males and 2 females aged 10-51 (avergae, 27.7) years] were included in this study. We assessed the presence of cruciate ligament tears at MR imaging, correlating the findings with those of surgery. Associated intra-articular injuries, treatment methods and follow-up results were also evaluated. Among seven patients with ACL avulsion injury, this was assessed at MR imaging as complete tear (n=1), partial tear (n=5), or intact (n=1), while all MR images of PCL avulsion injury (n=3) showed that this was partial teat. All imaging findings corresponded with the surgical findings. In four patients there was associated knee injury involving, respectively, teats of the medial meniscus, lateral meniscus, PCL and MCL, and popliteal ligament. Our findings showed that with one exception, patients with avulsion injury of the ACL or PCL had suffered either a partial or complete tear. MR imaging may be useful in the diagnosis of tears of the cruciate ligament which have not been noticed at surgery or arthroscopy in avulsion injuries involving the ACL and PCL.

  9. Scintigraphy for diagnosis of avulsions of the origin of the suspensory ligament in horses: 51 cases (1980-1993)

    International Nuclear Information System (INIS)

    The medical records of 34 horses with a diagnosis of avulsion of the origin of the suspensory ligament that had been admitted to the veterinary medical teaching hospital between 1980 and 1993 were identified. In addition to clinical examination, 21 of 34 horses had scintigraphy and radiography performed during their examination. The usefulness of scintigraphy and radiography were assessed by comparing the initial findings reported in the medical record to those obtained in a retrospective review of the images. Thirty other horses with scintigraphic lesions of the proximal aspect of the third metacarpal/metatarsal bone but with a confirmed diagnosis other than avulsion of the suspensory ligament served as controls for lesion specificity. Scintigraphy (bone phase, n = 21) revealed increased uptake in all horses in both reviews. Only 14 of 21 (67%) horses radiographed, however, had at least 1 lesion during the initial radiographic evaluation that was reported to be suggestive of avulsion. When the radiographs were reviewed retrospectively, the radiologist identified 18 of 21 (86%) horses with lesions consistent with avulsion. The interpretation of scintigraphy appeared to be a more repeatable and sensitive diagnostic method than radiography. However, though scintigraphy was sensitive in identifying inflammation of the proximal aspect of the metacarpal/metatarsal region, no specific diagnosis of avulsion could be made without coincident radiography; the specificity of scintigraphy in diagnosing avulsion of the suspensory ligament was only 41% (21/51)

    Full Text Available Direct ear trauma through external auditory canal causing an avulsion injury of malleoincudal complex is a grievous injury that can happen during ear cleaning with indigenous ear hook. One such case of avulsion injury is presented here with its symptomatology, investigation, and management with the review of available literature because of its rarity. Various locally designed indigenous ear hooks are available in street side markets and even online for purchase and used by many without knowing its ill effects on health. Injury caused by these types of hooks may lead to a severe hearing disability, if not properly treated. This presentation is to highlight the fact that indigenous ear hooks; rampantly available online for purchase can cause a potentially major injury leading to hearing disability and thereafter poor quality of life. Reporting and highlighting of such incidents among the ENT community can help increase the public awareness; thereby, eliminating such disastrous consequences.

  11. Nontraumatic avulsion of the lesser trochanter: A pathognomonic sign of metastatic disease?

    International Nuclear Information System (INIS)

    Isolated avulsion fractures of the lesser trochanter resulting from trauma are most commonly seen in adolescent athletes and are rare in adults. Standard therapy is nonsurgical with bedrest and immobilization of the leg. However, when this lesion is seen in the adult without significant trauma, it should be regarded as secondary to metastatic neoplasm until proven otherwise. Treatment should be surgical with prophylactic internal fixation of the hip to help prevent the commonly associated subtrochanteric pathologic fracture. In a patient without a known primary malignancy, biopsy should be carried out before therapy. We describe four patients with isolated avulsion fracture of the lesser trochanter due to metastatic carcinoma. Radiologists should be aware of this lesion because its presence has a decisive effect on therapy. (orig.)

    2015-01-01

    Full Text Available Background: The open reduction with internal fixation is an effective approach for treatment of avulsion fracture of posterior cruciate ligament. The previously used internal fixation materials including hollow screws, absorbable screw, tension bands and sutures have great defects such as insufficient fixation strength, susceptibility to re-fracture, etc. Stellate steel plate is novel material for internal fixation which has unique gear-like structure design. We used stellate steel plate for treatment of displaced avulsion fractures of posterior cruciate ligament in this study. Materials and Methods: 14 patients (9 men, 5 women; aged, 19-35 years; mean age, 28 years with displaced avulsion fractures of the tibial insertion of the posterior cruciate ligament were retrospectively analyzed between June 2009 and June 2011. The mean duration from injury to the operation was 8.3 days (range 6-15 days. All the patients were treated with open reduction and internal fixation of a stellate steel plate (DePuy, Raynham, MA 02767, USA. The Lysholm-Tegner knee function score criteria were used to analyze results. Results: The mean followup was 24.6 months (range 18-32 months. After 6 months, all the fractures healed and knee joint activity was normal, with no knee stiffness or instability. The Lysholm-Tegner scores were 97.1 ± 1.7 points at the final followup. Conclusion: Owing to its unique gear structure, the stellate steel plate design can effectively fix an avulsion fracture block and it is a simple operation with short postoperative rehabilitation time and firm fixation.

    Objective: To evaluate the diagnostic value of X-ray and MRI of avulsion fracture in tibial intercondylar eminence. Methods: X-ray and MRI images of 32 patients with avulsion fracture in tibial intercondylar eminence were retrospectively analyzed. All the cases were confirmed by arthroscopy. X-ray examinations were obtained from a standard anteroposterior and lateral views, part of them with oblique views. Axial FSE-T2WI, sagittal SE-T1WI, FSE-T2WI, STIR and coronal FSE-T2WI, GRE-STIR were examined in MRI examinations. Results: X-ray showed 28 correct diagnoses (87.5%) and 4 occult fracture misdiagnosis (12.5%), however, all the cases were correctly diagnosed with MRI (100%). In the patients which were correctly diagnosed by X-ray, MRI showed other lesions of knee joints (28/28), including 26 cases cruciate ligament trauma, 7 cases meniscus trauma, 4 cases collateral ligament trauma, 26 cases bone-contusion, and 6 cases other fracture. In the patients which were missed diagnoses in X-ray examinations, 3 cases showed cruciate ligament trauma, 1 case showed meniscus trauma, and 2 cases showed bone-contusion in MRI. Conclusion: Avulsion fracture in tibial intercondylar eminence were often associated with other knee joints lesions, which can be treated by arthroscopy directly if they were diagnosed by X-ray examinations. However, occult fractures should be examined by MRI, which can offer detailed information for clinic treatment. (authors)

    Full Text Available There is evidence indicating that pomegranate juice contains many of the essential properties necessary to retain cell viability and cell proliferation. These properties indicate that pomegranate juice is a suitable storage medium for avulsed teeth. However, this idea has not yet been tested. In this study, the capacity of pomegranate juice (PJ as a storage medium for retaining avulsed teeth was evaluated.PDL fibroblasts were obtained from healthy human premolars and cultured in Dulbecco's Modified Eagle's Medium (DMEM. Cultured cells were subjected to different concentrations of pomegranate juice (PJ, 1% Hank's balanced salt solution (HBSS and tap water for 1, 3, 6 and 24 hours. PDL cell viability was assessed by the neutral red uptake assay.The results indicated that 7.5% PJ was the most effective solution for maintaining PDL cell viability amongst all the experimental solution's and time intervals (P<0.05. The results also showed that 1% PJ was as effective as HBSS for maintaining PDL cell viability. The amount of cell viability increased with increasing concentration of PJ at all time intervals (P<0.001. This effect is suggestive of the proliferative potential of PJ solution.In conclusion, PJ can be recommended as a suitable transport medium for avulsed teeth.

    The Chubut River flows from the Andes to the Atlantic Ocean, and is interrupted by a single dam built at the middle valley. The lower valley is dominated by the aggradation of an alluvial plain induced by a complex of spits that enclosed the inlet in the last 5000 years. The river has reduced its flow because the blocking of the upper basin by terminal moraines during the Upper Pleistocene. At least the last two marine transgressions have flooded this estuary, and contributed to the aggradation during regressions. The area is of particular interest in regard to irrigation channels practiced since the XIX century. Today, the mean monthly flow is less than 10 m3/s although peaks of 95 m3/s have been recorded in Gaiman in July 2001. The dynamics of the estuary is dominated by waves (wave-dominated estuary) as tidal effects attenuate in less than 5 km. Three vibracores were collected within this floodplain: (a) at Gaiman, an area without any effect of the sea (35 km from the coast); (b) at Trelew, at the former avulsion plain of the river (18 km from the coast); and (c) at Playa Magagna, a saltmarsh located 0.4 km from the beach. At the Gaiman core (1.54 m long) fresh-water epiphytic diatoms dominate (Epithemia sorex, Cocconeis placentula, Ulnaria ulna) suggesting the aggradation of an alluvial plain. The Trelew core (2.19 m long) was collected from a deltaic plain. It was composed by fine sand with organic matter at the base that evolved into silty layers to the top. Several unconformities and laminae with heavy minerals were detected by their geochemical composition analysed by micro X-ray fluorescence (Itrax XRF core scanner). Fine-sand laminated layers were perfectly detected by their high content in S and Cl. On the other hand, mud layers presented lower content in Mg and Al with increments in Ca and V. The core from the marsh area (1.67 m long) was analysed in terms of the diatom evolution in order to detect Holocene sea-level and salinity effects. The sand flats

  4. Feasibility of an automatic computer-assisted algorithm for the detection of significant coronary artery disease in patients presenting with acute chest pain

    International Nuclear Information System (INIS)

    Automatic computer-assisted detection (auto-CAD) of significant coronary artery disease (CAD) in coronary computed tomography angiography (cCTA) has been shown to have relatively high accuracy. However, to date, scarce data are available regarding the performance of auto-CAD in the setting of acute chest pain. This study sought to demonstrate the feasibility of an auto-CAD algorithm for cCTA in patients presenting with acute chest pain. We retrospectively investigated 398 consecutive patients (229 male, mean age 50 ± 21 years) who had acute chest pain and underwent cCTA between Apr 2007 and Jan 2011 in the emergency department (ED). All cCTA data were analyzed using an auto-CAD algorithm for the detection of >50% CAD on cCTA. The accuracy of auto-CAD was compared with the formal radiology report. In 380 of 398 patients (18 were excluded due to failure of data processing), per-patient analysis of auto-CAD revealed the following: sensitivity 94%, specificity 63%, positive predictive value (PPV) 76%, and negative predictive value (NPV) 89%. After the exclusion of 37 cases that were interpreted as invalid by the auto-CAD algorithm, the NPV was further increased up to 97%, considering the false-negative cases in the formal radiology report, and was confirmed by subsequent invasive angiogram during the index visit. We successfully demonstrated the high accuracy of an auto-CAD algorithm, compared with the formal radiology report, for the detection of >50% CAD on cCTA in the setting of acute chest pain. The auto-CAD algorithm can be used to facilitate the decision-making process in the ED.

    We report nine cases of stress-related avulsion fracture of the tarsal navicular in athletes. This uncommon over-use injury is thought to occur following repetitive cyclic compressive loading secondary to an impingement of the tarsal navicular. The small dorsal triangular fragment is best seen in weightbearing lateral view radiographs and isotope scan and/or tomography help confirm the diagnosis. We feel that operative treatment is the method of choice in highly symptomatic cases and among top athletes because of the shorter recovery time. PMID:1897656

    The conventional treatment for an avulsed bronchus is emergent thoracotomy and repair or lobectomy. The principles of damage control thoracic operations include initial hemorrhage control with delayed definite repair after physiologic resuscitation. We report a multiply injured patient with avulsion of the left lower lobe bronchus. Profound acidosis, hypercarbia, and hypoxia precluded an emergent operation, and venovenous extracorporeal membrane oxygenation (V-V ECMO) was used for organ support during physiologic resuscitation. After the achievement of physiologic repletion, a thoracotomy and lobectomy were performed while the patient was supported by V-V ECMO. PMID:27211954

    Bilateral carotid and vertebral rete mirabile (CVRM) is a very rare condition. We report a new case of CVRM initially detected by magnetic resonance imaging (MRI) of the cervical spine. MRI demonstrated tortuous vascular signal voids limited to the anterior cerebrospinal fluid space mimicking spinal dural arteriovenous fistula. A diagnosis of CVRM was confirmed on the basis of angiographic findings of rete formation associated with bilateral aplasia of the cavernous internal carotid and vertebral arteries without abnormal arteriovenous connection.

    Endovascular abdominal aortic aneurysm repair (EVAR) and thoracic aortic aneurysm repair (TEVAR) have been widely incorporated into clinical practice. However, changes in arterial stiffness and post-implantation syndrome after aortic endografting remain important issues under investigation. The aneurysm sac wall motion after successful EVAR and TEVAR reflects complex interactions between all the components of the excluded aneurysm, including true compliance of the aneurysm wall itself, intra-aneurysm sac pressure, remodeling of the thrombus, and mechanical characteristics of the endograft. Experimental and clinical studies have shown that aortic endografting results in increased arterial stiffness in animal models. It can be assumed that the alterations of aortic mechanical properties can have a direct impact on heart output. The long-term impact of these mechanical changes on cardiovascular outcomes and the potential effects of different endografts on hemodynamics are important issues under investigation. Post-implantation syndrome (PIS) is a systemic inflammatory response frequently observed after endovascular treatment of aortic pathologies. The main features of PIS include fever, leukocytosis, elevated C-reactive protein levels, and coagulation disturbances. Endograft design appears to influence this inflammatory response following aortic endografting; woven polyester endografts have been shown to be associated with greater inflammatory response compared to PTFE stent grafts. The purpose of this paper is to review the literature to elucidate arterial stiffness alterations and inflammatory response after EVAR and TEVAR and the impact of endograft design on aortic stiffness and the post-inflammatory response.

    Material and methods: Image data of 151 patients suffering from coronary artery disease were calculated by means of retrospective triggering at four different diastolic delay times in contrast-enhanced CT. The large coronary segments were subsequently reconstructed in two planes with multiplanar volume reconstruction (MPVR). Results: On the pre-condition that data sets were acquired at sinus rhythm and at a heart beat rate lower than 65/min coronary arteries could be depicted over a long distance in single or double angulated reconstruction planes with the help of MPVR. Time consumption for image reconstruction was reasonable. Additionally to the anatomy of the coronary arteries in two different planes, typical CT findings in occluding coronary artery disease are presented. (orig.) [German] Material und Methode: An 151 Patienten mit koronarer Herzkrankheit wurden Bilddatensaetze mit dem Verfahren der retrospektiven Triggerung zu vier unterschiedlichen Zeitpunkten in der Diastole berechnet.

    2016-01-01

    Background: Disruption of the triangular fibrocartilage complex (TFCC) foveal insertion can lead to distal radioulnar joint (DRUJ) instability accompanied by ulnar-sided pain, weakness, snapping, and limited forearm rotation. We investigated the clinical outcomes of patients with TFCC foveal tears treated with arthroscopic-assisted repair. Materials and Methods: Twelve patients underwent foveal repair of avulsed TFCC with the assistance of arthroscopy between 2011 and 2013. These patients were followed up for an average of 19 months (range 14–25 months). The avulsed TFCC were reattached to the fovea using a transosseous pull-out suture or a knotless suture anchor. At the final followup, the range of motion, grip strength and DRUJ stability were measured as objective outcomes. Subjective outcomes were assessed using the Visual Analog Scale (VAS) for pain, patient rated wrist evaluation (PRWE), Disabilities of the Arm, Shoulder and Hand questionnaire (DASH score) and return to work. Results: Based on the DRUJ stress test, 5 patients had normal stability and 7 patients showed mild laxity as compared with the contralateral side. Postoperatively, the mean range of pronation supination increased from 141° to 166°, and the mean VAS score for pain decreased from 5.3 to 1.7 significantly. The PRWE and DASH questionnaires also showed significant functional improvement. All patients were able to return to their jobs. However, two patients complained of persistent pain. Conclusions: Arthroscopically assisted repair of TFCC foveal injury can provide significant pain relief, functional improvement and restoration of DRUJ stability. PMID:27293286

    Full Text Available Background: Tooth avulsion is one of the most severe dental traumas which most often occur in children. When immediate replantation is not possible, storage in a proper media may lead to a prolonged survival rate. Aloe Vera is a cactus like plant with green, tapered leaves that are filled with a transparent viscous gel. This medicinal plant has significant anti-inflammatory, antioxidant, antibacterial and antifungal effects. The purpose of this study was to assess the effectiveness of different concentrations of Aloe Vera extract compared to DMEM (cell culture medium and egg white. Methods: The periodontal ligament (PDL cells were cultured and certain number of cells were treated with Aloe Vera extract (in four different concentrations, egg white and culture media for 1, 3, 6, and 9 hours. Cell viability was determined by using the (3-[4, 5-dimethylthiazolyl-2]-2, 5-diphenyltetrazolium bromide assay. Moreover, One-way ANOVA and post hoc (LSD test were used for analyzing the study groups. Results: The results indicate that culture media and Aloe Vera extract (10, 30, and 50% concentration were statistically similar and significantly preserved more PDL cells compared to other experimental storage media. Conclusion: Aloe Vera 10, 30, and 50% may be recommended as a suitable storage media for avulsed teeth.

    2012-07-01

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

    To find and describe the cerebellar arteries arising from the internal carotid artery, explain them embryologically, and evaluate their clinical implication. To determine the point in the internal carotid artery from which the cereballar artery arose anomalously, consecutive angiographic studies performed in the last three years were reviewed. The distribution of such anomalous cerebellar arteries, the point in the internal carotid artery from which the anomalous vessels originated, and associated findings were analyzed. Five anomalous origins of cerebellar arteries arising arising directly from the internal carotid artery were found in five patients. Three anterior inferior cerebellar arteries (AICA) and one common trunk of an AICA and a posterior inferior cerebellar artery (PICA) were found to originate from the internal carotid artery at a point close to the origin of the primitive trigeminal artery. A PICA arose from an artery presenting a course similar to the proatlantal intersegmental artery. Intracranial aneurysms in two patients, Moyamoya disease in one, and facial arteriovenous malformation in one. In our series, AICAs supplied from the arteries considered to be persistent trigeminal artery variants were the most common type. A correlation between type of anomalous cerebellar artery and type of carotid-vertebrobasilar anastomosis may exist. Cerebellar arteries originating anomalously from the internal carotid artery seem to occur as a result of the persistence of carotid-vertebrobasilar anastomoses associated with incomplete fusion of the longitudinal neural arteries. An understanding of these anomalous cerebellar arteries may help prevent accidents during therapeutic embolization and surgical treatment, as well as misinterpretation.

  3. Diagnosis of nerve root avulsion injuries in adults with traumatic brachial plexopathies: MRI compared with CT myelography

    Directory of Open Access Journals (Sweden)

    Ewoudt van der Linde

    2015-03-01

    Full Text Available Background: Computed tomography myelography (CTM has been broadly adopted as the ‘gold standard’ imaging technique in the diagnosis of nerve root avulsion injuries in traumatic brachial plexopathies. CTM has the distinct advantage of better spatial resolution than magnetic resonance imaging (MRI; however, this technique is invasive and can result in significant patient discomfort. MRI, therefore, seems relatively more advantageous as it is less invasive (requires no lumbar puncture, lacks radiation exposure, has no adverse reactions related to intrathecal contrast agents and confers excellent soft-tissue contrast. Objectives: To compare the sensitivity and specificity of MRI with CTM in the diagnosis of preganglionic nerve root avulsion injuries in adults with traumatic brachial plexopathies at the Inkosi Albert Luthuli Central Hospital.Method: A retrospective comparative analysis was performed on 16 adult patients with traumatic preganglionic brachial plexopathies who underwent both MRI and CTM at Inkosi Albert Luthuli Central Hospital. Radiologists experienced in both CTM and MRI interpreted the data and a comparison was made using CTM as the gold standard. Results: The sensitivity and specificity for MRI detecting preganglionic nerve root avulsion injuries and pseudomeningoceles was 82% and 100% respectively. The interobserver agreement between CTM and MRI for the detection of preganglionic nerve root avulsion injuries was 81.25% (Kappa = 0.77 and 87.5% (Kappa = 0.84 for the detection of pseudomeningoceles. Conclusion: MRI was as sensitive as CTM at detecting preganglionic nerve root avulsion injuries and pseudomeningoceles of spinal nerve roots C7–T1 of the brachial plexus. Some mild discrepancies existed at the C5 and C6 nerve root levels. Owing to the invasiveness of the procedure and resultant patient discomfort, CTM should be reserved for complicated cases or for patients with contraindications to MRI.

    2012-01-01

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    interpreted as stable ‘‘transport log jams’’ formed during floods, although some may have been ‘‘unstable jams’’ stranded on bars during peak-flow recession. Associated with the logs are extrabasinal gravel and intraclasts of mudstone and coal, which suggest that floods in sediment-choked channels undercut...... banks of gravelly sand capped by mud and forested peat, widened the channels, and toppled riparian vegetation. An estimated blockage ratio of 8% for one accumulation (ratio of the cross-sectional areas of the log jam and host channel) is close to the 10% value considered to cause substantial blockage in...... some modern rivers. In two instances, a radical change in paleoflow between pre- and post-abandonment channels is consistent with an interpretation that log jams and flood sediment buildup promoted channel-belt avulsion. Although large trees had evolved by Middle to Late Devonian times, it is unlikely...

  7. The "flying" bile duct: avulsion of the common bile duct in a plane crash survivor.

    LENUS (Irish Health Repository)

    Mohan, H

    2012-02-01

    Blunt trauma is an unusual cause of extrahepatic bile duct injury. This is a case of a 51-year-old gentleman who sustained a significant seatbelt injury in a plane crash. Laparotomy, performed due to persistent abdominal pain, revealed that the common bile duct (CBD) was completely avulsed from the duodenum. Following insertion of drains and transfer to a hepatobiliary centre, the devascularised CBD was excised and replaced with a roux-en-y hepaticojejunostomy. Necrotic tissue was debrided from the pancreatic head. A persistent bile leak developed from the sub-hepatic drain. Repeat laparotomy revealed a bile leak from small ducts on the liver surface. Ligation of the ducts and bioglue sealing of the area were successfully performed. Subsequent to this a pancreatic fistula developed from the main pancreatic duct, which has since resolved. This unusual case illustrates the need for prompt recognition and early repair to optimise outcomes in traumatic CBD injury.

    2009-12-01

    The type IV flexor digitorum profundus avulsion is a rare injury involving fracture of the volar base of the distal phalanx and separation of the tendon from the fracture fragment. Recommendations for management are sparse and are substantiated only by a few isolated case reports. We recently encountered two of these injuries, both of which proved challenging, particularly with regard to joint incongruity and tendon adhesions. In reviewing the literature, it is apparent that no consensus exists regarding surgical strategies. However, based on our experience and that of other authors, we can suggest the following: (1) high index of suspicion of this potentially deceptive injury, with use of magnetic resonance imaging or ultrasound if preoperative confirmation is needed; (2) rigid bony fixation that prevents dorsal subluxation of the distal phalanx; (3) tendon repair that is independent of the bony fixation; and (4) early range of motion therapy.

  9. Experimental studies on the treatment of traumatic dental avulsion in dogs

    International Nuclear Information System (INIS)

    The experiments were performed on 7 dogs aged between 2 and 4 years weighing 12-16 kg in the period October 1998- January 2000. After anaesthesia, the following dental procedures were accomplished; performance of a dental avulsion, endodontic treatment, apical dentotomy, tooth replantation and fixation with an orthodontic splint, figure-of-eight wire ligature and photopolymer. The treatment was effective in 71.4% of experimental replantations of incisors and the replanted teeth persisted for more than 8-9 months. The radiological survey showed that the regeneration began as early as the first post replantation days. In the period between days 30-45, a bone bridging was observed and the regeneration was complete by the end of the second month

    Five cases of internal carotid-cerebellar artery anastomosis are presented. These anomalous vessels are identical to the so-called persistent trigeminal artery variant (PTAV). In our cases, two superior cerebellar arteries (SCAs), two anterior inferior cerebellar arteries (AICAs) and one posterior inferior cerebellar artery (PICA) arose from the precavernous segment of the internal carotid artery. We discuss the embryolgical and neuroradiological aspects of this anomaly.

    When complete revascularization cannot be obtained with the internal thoracic artery and the other arterial grafts, the deep circumflex iliac artery (DCIA) may be an excellent alternative conduit. The deep circumflex iliac artery was used as a free graft for direct myocardial revascularization in 4 patients from January to July 1999. We describe our experience with this arterial conduit, review the anatomy of the artery, and present our harvesting technique. PMID:10735725

    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.

    Summary 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

    Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is very rare. We present this uncommon anomalous artery along with digital subtraction angiography findings and discuss its clinical significance in light of the literature. PMID:19821254

  17. Dry Endoscopic-Assisted Mini-Open Approach With Neuromonitoring for Chronic Hamstring Avulsions and Ischial Tunnel Syndrome

    Chronic hamstring origin avulsions and ischial tunnel syndrome are common causes of posterior hip pain. Although physical therapy has shown benefits in some cases, recent evidence has reported better outcomes with surgical treatment in appropriately selected patients. The full-open approach has been the classic procedure to address this problem. However, the complications related to extensive tissue exposure and the proximity of the incision to the perianal zone have led to the description of full-endoscopic techniques. Achieving an accurate hamstring repair could be technically demanding with a full-endoscopic procedure. Accurate reattachment is crucial in hamstring repair because of the functional demand of the muscles crossing of 2 major joints (hip and knee). This surgical note describes a mixed technique including a mini-open approach, neuromonitoring, and dry endoscopic-assisted repair of the hamstring origin as an alternative for treating patients with chronic hamstring avulsions and ischial tunnel syndrome that remain symptomatic despite nonoperative treatment.

    Full Text Available Brachial plexus root avulsion (BPRA leads to dramatic motoneuron death and glial reactions in the corresponding spinal segments at the late stage of injury. To protect spinal motoneurons, assessment of the affected spinal segments should be done at an earlier stage of the injury. In this study, we employed 18F-FDG small-animal PET/CT to assess the severity of BPRA-induced cervical spinal cord injuries. Adult Sprague-Dawley rats were randomly treated and divided into three groups: Av+NS (brachial plexus root avulsion (Av treated with normal saline, Av+GM1 (treated with monosialoganglioside, and control. At time points of 3 day (d, 1 week (w, 2 w, 4 w and 8 w post-injury, 18F-FDG micro-PET/CT scans and neuropathology assessments of the injured spinal roots, as well as the spinal cord, were performed. The outcomes of the different treatments were compared. The results showed that BPRA induced local bleeding and typical Wallerian degeneration of the avulsed roots accompanied by 18F-FDG accumulations at the ipsilateral cervical intervertebral foramen. BPRA-induced astrocyte reactions and overexpression of neuronal nitric oxide synthase in the motoneurons correlated with higher 18F-FDG uptake in the ipsilateral cervical spinal cord during the first 2 w post-injury. The GM1 treatment reduced BPRA-induced astrocyte reactions and inhibited the de novo nNOS expressions in spinal motoneurons. The GM1 treatment also protected spinal motoneurons from avulsion within the first 4 w post-injury. The data from this study suggest that 18F-FDG PET/CT could be used to assess the severity of BPRA-induced primary and secondary injuries in the spinal cord. Furthermore, GM1 is an effective drug for reducing primary and secondary spinal cord injuries following BPRA.

  1. Magnetic resonance imaging of the cervical nerve root avulsion in brachial plexus injuries. New imaging technique and classification

    International Nuclear Information System (INIS)

    The Author describes a new magnetic resonance (MR) imaging technique of the cervical nerve roots in traumatic brachial plexus injury. The overlapping coronal-oblique slice MR imaging procedure of the cervical nerve root was performed in 35 patients with traumatic brachial plexus injury. The results were retrospectively evaluated and classified into four major categories (normal rootlet, rootlet partial injuries, avulsion, and meningocele), after diagnosis by surgical exploration. In this study, the sensitivity of detection of the cervical nerve root avulsion in MR imaging was the same (92.9%) as that of myelography and CT myelography. The reliability and reproducibility of the MR imaging classification was prospectively in 10 patients with traumatic brachial plexus injury, assessed by eight independent observers, and its diagnostic accuracy was compared with that of myelography and CT myelography. In this study, interobserver reliability and intraobserver reproducibility showed that there were no statistically significant difference between both modalities. This new MR imaging technique is a reliable and reproducible method for detecting nerve root avulsion, and the MR imaging information provided valiable data for helping to decide whether to proceed with exploration, nerve repair, primary reconstruction, or other imaging modalities.

    Brachial plexus injury (BPI) often involves the complete or partial avulsion of one or more of the cervical nerve roots, which leads to permanent paralysis of the innervated muscles. Reimplantation surgery has been attempted as a clinical treatment for brachial plexus root avulsion but has failed to achieve complete functional recovery. Lithium is a mood stabilizer drug that is used to treat bipolar disorder; however, its effects on spinal cord or peripheral nerve injuries have also been reported. The purpose of this study was to investigate whether lithium can improve functional motor recovery after ventral root avulsion and reimplantation in a rat model of BPI. The results showed that systemic treatment with a clinical dose of lithium promoted motor neuron outgrowth and increased the efficiency of motor unit regeneration through enhanced remyelination. An analysis of myelin-associated genes showed that the effects of lithium started during the early phase of remyelination and persisted through the late stage of the process. Efficient remyelination of the regenerated axons in the lithium-treated rats led to an earlier functional recovery. Therefore, we demonstrated that lithium might be a potential clinical treatment for BPI in combination with reimplantation surgery. PMID:27185485

    Anomalous coronary arteries that course between the aorta and pulmonary artery are subject to compressive forces and can manifest angina, myocardial infarction and sudden death. The current report presents a young, female patient who presented with a short duration of severe, rapidly progressive angina despite optimal medical therapy. Combined computed tomography and myocardial perfusion scanning identified an anomalous dominant right coronary artery that appeared kinked at its origin between the aorta and main pulmonary artery. A robot-assisted right internal thoracic artery to right coronary artery bypass was performed, which was confirmed to be widely patent (FitzGibbon grade A) on routine intraoperative angiography. The procedure completely resolved the patient's angina symptoms. PMID:20931103

     Vascular anatomy of the liver is varied, and the"standard"anatomy is seen in 55%-80%of cases. It is very important that extrahepatic arteries are identiifed precisely at the time of graft procurement to avoid injuries that might compromise the liver function. In the present case the liver donor had the vascular anatomy of Michels type Ⅶ, e.g. a hepatic artery originating from the celiac trunk and going to the left lobe, an accessory left hepatic artery coming from the left gastric artery, and a replaced right hepatic artery coming from the superior mesenteric artery. This pattern of vascular supply is uncommon, representing less than 5%of cases. The replaced hepatic artery was reconstructed in the back-table with polypropylene suture 7.0 by connecting it to the stump of the splenic artery, and the celiac trunk of the graft was anastomosed to the recipient common hepatic artery.

    Full Text Available Basilar artery thrombosis has high morbidity and mortality. Though intra-arterial thrombolytics have proven efficacy in the treatment of acute basilar artery occlusion, the elevation of procoagulant factors in the blood after intra-arterial thrombolysis could result in subsequent thrombus formation and clinical deterioration. Glycoprotein IIb/IIIa inhibitors have been shown to reduce this elevation in procoagulants. We present a pilot study of three cases of acute basilar artery occlusion treated with a combination of intra-arterial thrombolytics and Gp IIb/IIIa inhibitor with remarkable clinical recovery seen in all the patients.

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

  16. A case study of an axillary artery pseudoaneurysm following anterior dislocation of the glenohumeral joint: A rare presentation on plain film radiographs

    International Nuclear Information System (INIS)

    Axillary pseudoaneurysm is a rare but important complication of anterior glenohumeral joint dislocation. Diagnosis of axillary pseudoaneurysm is predominantly undertaken following clinical examination but where diagnosis is uncertain, Doppler ultrasound is the imaging examination of choice to confirm diagnosis. In this case study, the initial clinical signs of axillary pseudoaneurysm were masked by the presenting trauma and, although findings indicative of pseudoaneurysm were present on late plain film images, they were not immediately recognised. Misdiagnosis or delayed diagnosis of axillary pseudoaneurysm may result in upper limb morbidity or patient mortality. Consequently, the prompt and accurate identification of an axillary pseudoaneurysm on plain film radiographs, although rare, is essential. Yet for inexperienced film readers, correctly identifying an axillary pseudoaneurysm can be difficult due to its apparent similarity to other pathologies. This article will highlight the differences in radiological appearances between a pseudoaneurysm and a gleno-humeral joint effusion to raise radiographer awareness of the risks and clinical signs of an axillary pseudoaneurysm post gleno-humeral joint dislocation and discuss the difficulties encountered in its diagnosis. Finally, this review will evaluate current diagnostic practices in comparison with best practice, as identified in the literature [Fitzgerald JF, Keates J. False aneurysm as a late complication of anterior shoulder dislocation. Ann Surg 1975;6:785-6; Drury JK, Scullion JE. Vascular complications of anterior dislocation of the shoulder.

    2016-06-01

    Basilar artery thrombosis constitutes 1% of all types of stroke, carries a mortality rate of up to 90%, and is one of the rarer causes of sudden death. It leads to brain stem ischemia and commonly presents with impaired consciousness, cranial nerve palsy, hemiplegia or quadriplegia, and sudden collapse. Clinically, the diagnosis of basilar artery thrombosis is made on clinical symptoms, along with a hyperdense basilar artery in antemortem computed tomography (CT) scan. To our knowledge, whether a hyperdense basilar artery indicates basilar artery thrombosis on postmortem CT scan is not documented in the literature. We present a case report of a 55-year-old man who on postmortem CT scan showed a hyperdense basilar artery and was subsequently confirmed to be a fatal basilar artery thrombosis. We suggest that a hyperdense basilar artery on postmortem CT should prompt the pathologist to consider basilar artery thrombosis. PMID:27049662

However, occurrence of superficial ulnar artery associated with unusual origin of the common interosseous and ulnar recurrent arteries is seldom reported in the literature. In the present case, we report the anomalous origin of common trunk of common interosseous, anterior and posterior ulnar recurrent arteries from the radial artery, in a male cadaver. Further, ulnar artery had presented superficial course. Knowledge of anomalous arterial pattern in the cubital fossa reported here is clinically important during the angiographic procedures and plastic surgeries. PMID:27437201

    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...

  3. Irradiation injury to large arteries

    International Nuclear Information System (INIS)

    Four cases of irradiation injury to large arteries following radiotherapy treatment are presented and the literature is reviewed. Three patterns of injury have emerged: 1) intimal damage resulting in mural thrombosis presenting within 5 years of irradiation, 2) fibrotic occlusion presenting within 10 years of injury, and 3) a predisposition to the development of atheroma together with periarterial fibrosis associated with a latent interval of 20 or more years. The treatment of choice is a bypass procedure of the arterial lesion. (author)

    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 This paper aimed to define the origin and distribution of the celiac artery and its collateral branches in 15 fowls from the Columba livia species, which were obtained from the Zoonosis Control Center of Brasilia, Brazil. In order to mark the arterial system of the specimens, the left brachiocephalic trunk was canullated and a colored water-latex solution was injected there. Afterwards, fowls were fixed in a 10% v/v formaldehyde solution and dissected with appropriate equipment, presenting the results described in this paper. The celiac artery originated from the ventral face of the descendent aorta. The first collateral branch arose from the celiac artery itself, forming the esophageal artery. Then, the celiac artery has bifurcated into two branches, named left and right branches of the celiac artery. The left branch emitted the proventricular ventral artery, followed by the splenic arteries, proventricular dorsal artery, and the left hepatic artery. The left branch has bifurcated into two branches, known as ventral and left gastric arteries. The right branch emitted the right hepatic artery, followed by the ileal artery and the right gastric artery. Finally, the right branch turned into the pancreaticoduodenal artery. Our findings showed a great similarity with the avian lineages of the Gallus gallus species, except for the lack of ileocecal artery, cystic branches, and dorsal gastric artery.

    . Four palaeochannels are visible on the floodplain's surface, these being also evident in the sedimentary structure of the valley infill, as revealed by the electrical imaging and drilling. Former channel infills consist mainly of massive and sandy clays (low electrical resistivity - 5.8 ohm.m), whereas the sectors between them are filled by pebbles and sands interpreted to be channel deposits (high values of the electrical resistivity - 80 ohm.m).The absence of coarse gravels from the bottom, direct disposal of fine sediments on marls and the presence of massive clay suggests 3 stages in the channels evolution. The first one is a long period of stability, supposed to be associated to a low sinuous course, when river incised the sedimentary complex of the floodplain, until it was intersected the valley bottom. The second stage is an abrupt avulsion to the right, produced probably during an important flood, and the third stage corresponds to the period of complete abandonment of it and the evolution as oxbow lake. If we take in consideration the presence of the diapiric syncline on the right side of the valley, and the disposal of parallel channels with it (including the present-day one), we conclude that this behavior is caused by a lateral tilting of the floodplain trough the right.

  10. Avulsion fractures of tibial tributary's in adolescents: Treatment with closed reduction and percutaneous screwing, using MRI to identify combined intraarticular lesions

    International Nuclear Information System (INIS)

    Avulsion fracture of the tibial tuberosity is an uncommon lesion generally seen in adolescents. Intra-articular lesions combined with a tibial tuberosity fracture reported in the literature are; 3 patellar tendon ruptures, 2 anterior cruciate ligament tears, 2 medial collateral ligament tears, 2 medial meniscus tears, one arcuate ligament tear, and one lateral meniscus tear. In our study, both cases sustained an avulsion fracture of the tibial tuberosity. Preoperative MRI in one case revealed posterior cruciate ligament rupture. Under the image intensifier, we treated both patients by closed reduction and percutaneous screwing with 2 cancellous screws. Radiographic assessment showed complete healing of the avulsion fractures in both cases. Both of our patients gained previous levels of daily and sporting activity prior to the injury, and were completely asymptomatic. Our objective in reporting this case study is to point to the fact that there is no previous reporting of the avulsion fracture of the tibial tuberosity accompanied by posterior cruciate ligament rupture in the literature and to evaluate the findings of the minimal invasive treatment method we applied to both cases.

    In this work are presented the results of localization of foot arteries, in a young group of participants by using infrared thermal images, these are the dorsal, posterior tibial and anterior tibial arteries. No inclusion criteria were considered, that causes that no strong statistical data about the influence of the age in the arterial localization. It was achieved to solve the confusion when veins present a heat distribution similar to the artery and in the position of this. it contributes to enhance the rate of location of arteries. In general it is possible to say that the use of infrared thermal images is a good technique to find the foot arteries and can be applied in its characterization in a future. The procedure proposed is a non-invasive technique, and in certain fashion does not requires specialized personnel to achieve locate the arteries. It is portable, safe, and relatively economical.

Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservative maneuvers performed did not improve visual acuity in the left eye. Supra-aortic Doppler ultrasonography revealed mild right internal carotid artery stenosis and moderate left internal carotid artery stenosis with a small, smooth, and homogeneous plaque. The transthoracic echocardiography showed a severe calcification of the mitral valve with a mild-moderate rim of stenosis. Central retinal artery occlusion and branch retinal artery occlusion are characterized by painless monocular loss of vision. Clinical approach and management attempt to treat the acute event, find the source of the vascular occlusion, and prevent further vascular events from occurring. Giant cell arteritis is a potentially treatable cause of central retinal artery occlusion and should be excluded in every single patient over 50 years old.Keywords: loss of vision, branch retinal artery occlusion, central retinal artery occlusion, Hollenhorst plaque

  13. Determination of arterial wall shear stress

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The arteries can remodel their structure and function to adapt themselves to the mechanical environment. In various factors that lead to vascular remodeling, the shear stress on the arterial wall induced by the blood flow is of great importance. However, there are many technique difficulties in measuring the wall shear stress directly at present. In this paper, through analyzing the pulsatile blood flow in arteries, a method has been proposed that can determine the wall shear stress quantitatively by measuring the velocity on the arterial axis, and that provides a necessary means to discuss the influence of arterial wall shear stress on vascular remodeling.

    Full Text Available Context: Many different patterns have been described to classify the origins of circumflex femoral arteries by many authors since from 1860.The aim of the present study was to classify the circumflex femoral arteries in 100 lower limbs of adult cadavers of both sexes following the recent classification and to compare with the previous studies. Materials and Methods: A total of 100 lower limbs of 50 embalmed human adult cadavers (Male: 37, Female: 13 were dissected and observed for the origins of circumflex femoral arteries in femoral triangle in routine educational dissection in the period of 2005-2009 Results: The medial and lateral circumflex femoral arteries have been classified into three different patterns based on the levels of their origin. Pattern I: Both arteries arose from the profunda femoris artery (56%. Type Ia, medial circumflex femoral artery origin was proximal to the lateral circumflex femoral artery origin (69%; Type Ib, lateral circumflex femoral artery origin was proximal to medial circumflex femoral artery origin (16 %; Type Ic, both arteries arose from a common trunk or at same level (14%. Pattern II: One of the arteries arose from the femoral artery and the other from the profunda femoris artery (36%. Type IIa, the medial circumflex femoral artery arose from the femoral artery (75% and Type IIb, the lateral circumflex femoral artery arose from the femoral artery (25%.Pattern III: Both arteries arose from the femoral artery (7%. The medial circumflex femoral artery was absent in a female cadaver on right side. Conclusion: In every pattern or type, there was significantly unilateral higher occurrence than bilateral occurrence. A precise knowledge of the circumflex femoral arteries in relation to the profunda femoris artery is important in surgical interventions of the hip region

    A 12-year-old boy presented with severe arterial hypertension due to a severe subsegmental renal artery stenosis. Treatment consisted of selective embolization of the stenosed polar artery, which resulted in near normalization of the arterial pressures. Renal artery stenosis should always be considered, even in young adolescents, as a cause for arterial hypertension. Only selective angiography was able to demonstrate the subsegmental artery stenosis in this patient. (orig.)

    2007-01-01

    The purpose of this study is to describe our technique of central slip repair using the Mitek bone anchor and to evaluate the treatment outcome. Eight digits in eight patients were reconstructed using the bone anchor: three little fingers, two middle fingers, two index fingers and one ring finger. There were two immediate and six delayed repairs (range from one day to eight months). Four patients had pre-operative intensive splinting and physiotherapy to restore passive extension of the proximal interphalangeal joint prior to central slip reconstruction. All patients have made good progress since surgery. No patient requires a second procedure and none of the bone anchors have dislodged or loosened. We conclude that the Mitek bone anchor is a reliable technique to achieve soft tissue to bone fixation in central slip avulsion injuries. We recommend that this technique be considered as a treatment option for patients requiring surgical repair.

  5. Computed tomography myelography with coronal and oblique coronal views for diagnosis of nerve root avulsion in brachial plexus injury

    International Nuclear Information System (INIS)

    We describe a new computed tomography (CT) myelography technique with coronal and oblique coronal views to demonstrate the status of the cervical nerve rootlets that are involved in brachial plexus injury. We discuss the usefulness of this technique for the diagnosis of nerve root avulsion compared with that of CT myelography with axial view. CT myelography was performed with enhancement of the cervical subarachnoid space by using a contrast medium. Subsequently, coronal and oblique coronal reconstructions were created. The results of CT myelography were evaluated and classified in the presence of pseudomeningocele, intradural ventral nerve rootlets, and intradural dorsal nerve rootlets. The diagnosis was based on the findings of extraspinal surgical exploration with or without spinal evoked potential measurements and choline acetyltransferase activity measurement in 25 patients and recovery by a natural course in 3 patients. The diagnostic accuracies of CT myelography with coronal and oblique coronal views and that with axial view were compared and correlated with the surgical findings or natural course in 57 cervical roots in 28 patients. Coronal and oblique coronal views were superior to axial views in the visualization of the rootlets and orientation of the exact level of the root. They showed 100% sensitivity, 96% specificity, and 98% diagnostic accuracy (26 true-positive findings, 27 true-negative findings, none false-positive findings, and one false-negative findings) for diagnosing root avulsion. No statistically significant difference was observed between the coronal and oblique coronal views and the axial views. The information obtained using coronal and oblique coronal slice CT myelography enabled the assessment of the rootlets of the brachial plexus and provided valuable data for deciding the appropriate treatment strategy, namely, exploration, nerve repair, or primary reconstruction.

  6. Legacy Morphologies: Channel Avulsions and Historical Engineering Structures Drive Form and Process in the Lower Yuba and Feather Rivers, California

    2008-12-01

    Geomorphic changes in the lower Yuba and Feather Rivers due to hydraulic mining provide a chance to study centennial-scale processes. Channel changes over 150 years were determined using channel-bank stratigraphy, geochemical signatures (total Hg, grain-size distributions, bulk geochemistry, fallout radionuclides, and Sr/Nd isotopes), and spatial analyses of high-resolution topographic data, historical maps, and aerial photos. Repeated avulsions and broad erosion/deposition patterns are shown, including a downstream shift in activity through time. In the 20th century, both rivers experienced deep main-channel incision and floodplain alluviation of natural levees and abandoned channels. Buried trees rooted in pre- mining soils indicate the Feather has not returned to pre-mining base levels below the Yuba confluence. Early engineering works controlled channel responses and recovery. For example, the Feather River avulsed into a channel dredged through Shanghai Bend (c.1907) so it now crosses resistant Quaternary alluvium over a 3-m knickpoint bench that could soon be breached. Moreover, levees and channelization near the Yuba-Feather confluence at Marysville (c.1905) narrowed and deepened flows, encouraging the bed incision noted by Gilbert. Effects of legacy sediment on channel processes are well known. Here, channel recovery was also constrained by channel morphologies engineered with boulder wing dams and revetment in the Yuba and channelization and levees in the Feather. The resulting bed incision reduces lateral connectivity between channels and floodplains and increases sediment conveyance. Historical and anthropogenic perspectives are essential to explaining channel dynamics at these scales. Unless models of channel and floodplain evolution recognize historical changes and engineering works, they may miss crucial components of geomorphic change and potential impacts downstream. In such systems, the historical dimension is essential to river management, water

Despite the common association of NF1 with neurocutaneous features, its pathology can extend to numerous tissues not derived from the neural crest. Among the rare cerebrovascular abnormalities in NF1, more than 85% of cases are of purely occlusive or stenotic nature, with intracranial aneurysm being uncommon. Predominantly, the aneurysms are located in the internal carotid arteries (ICAs, being very rare bilateral aneurysms. This report describes a very unusual case of fusiform aneurysms of both ICAs in a Caucasian NF1 patient, with a new pathogenic intragenic heterozygous deletion of the NF1 gene, presenting at age 22 years with Tolosa–Hunt syndrome, because of partial thrombosis of the left giant intracavernous aneurysm. Medical treatment with anticoagulant therapy allowed a good outcome for the patient. In conclusion, early identification of cerebral arteriopathy in NF1 and close follow-up of its progression by neuroimaging may lead to early medical or surgical intervention and prevention of significant neurologic complications.Keywords: neurofibromatosis type 1, NF1 gene, multiplex ligation

    The status of the periodontal ligament (PDL) and of the pulp are decisive for the healing of avulsed and replanted teeth. A tooth rescue box was developed and distributed to offer optimal storage conditions for avulsed teeth. The therapy comprised extraoral endodontic treatment and applications of medicaments to enhance periodontal healing. In this long-term clinical study the healing results following avulsion and replantation were investigated. Twenty-eight permanent teeth in 24 patients were evaluated. The extraoral storage media and periods varied considerably. Soon after avulsion six teeth were stored in a cell culture medium (tooth rescue box Dentosafe) for 1-53 h; the PDL was defined as not compromised. Sixteen teeth were stored in a non-physiologic situation temporarily, the PDL was considered as compromised. Six teeth were stored in non-physiologic conditions for longer periods; the condition of the PDL was defined as hopeless. On 14 teeth antiresorptive-regenerative therapy (ART) with the local application of glucocorticoids and enamel matrix derivative and the systemic administration of doxycyclin was used. In all teeth extraoral endodontic treatment by retrograde insertion of posts was performed. The mean observation period was 31.2 months (+/-24.1; 5.1-100.2; median: 23.8). All six teeth rescued physiologically healed with a functional PDL (functional healing, FH) irrespective of the storage period. Of eight teeth with a compromised PDL on which ART was used, three teeth healed with a functional PDL. All other teeth showed replacement resorption, in three teeth additionally infection-related resorption was recorded. The predominant influence on the healing results was the immediate physiologic rescue of avulsed teeth (chi-square, P = 0.0001). The use of ART seemed to support FH (chi-square, P = 0.0547) in teeth with a compromised PDL. No other factors (maturity of roots, crown fractures, gender, age, antibiotics) were related to healing.

  10. The brain plasticity in patients with brachial plexus root avulsion after contralateral C7 nerve-root transfer: a FDG-PET study

    International Nuclear Information System (INIS)

    Objectives: To study FDG-PET for imaging the brain plasticity in patients with brachial plexus root avulsion after contralateral C7 nerve-root transfer. Methods: One male patient with left brachial plexus root avulsion underwent a two-stage procedure (first phase: C7 root → ulnar nerve; second phase: ulnar nerve → recipient nerve) 4 years ago; Another with right brachial plexus root avulsion also underwent a two-stage procedure 3 years ago. First two patients underwent basic FDG-PET imaging, the next day FDG-PET scans were performed after initiative or passive limb movement. Using ROI and MPI tools to evaluate the images. The ratios of sensorimotor frontal cingulated Thalami to white matter were used as the semiquantitive index. Results: Whether brain plasticity had occurred was determined by whether the affected limb can perform initiative movement. The increases in glucose metabolism of left sensorimotor frontal cingulated Thalami in patient with left brachial plexus root avulsion were 40.1%, 37.9%, 48.3%, 31.9% after initiative movement, the right corresponding brain regions were 39.4%, 34.3%, 48.5%,35.4% respectively. However, the increases in glucose metabolism of left sensorimotor frontal cingulated Thalami in patient with right brachial plexus root avulsion were increased by 12.6%, 9.6%, 10.7%, 5.3% after passive movement, the right corresponding brain regions were respectively 17.9%, 12.9%, 15.4%, 10.1%. It was founded that the metabolism of bilateral sensorimotor frontal cingulated Thalami increased after initiative movement, while the metabolism of right sensorimotor frontal cingulated Thalami increased more obviously than that of the left brain regions when using MPI tool to substract the images before and after the affected limb movement. Conclusions: Sensorimotor frontal cingulated Thalami were necessary to the initiative movement. After being activated by movement, the metabolisms of plasticised brain regions increased obviously. However, the

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    Full Text Available Retinal artery occlusion is one of the vision-threating emergency situations in ophthalmology. In this paper, a case of retinal artery occlusion is presented. Fifty seven year- old female patient presented with a sudden onset visual loss in her left eye. Best corrected visual acuity (BCVA levels were 1.0 and 0.7 in the right and left eye, respectiveley. Dilated fundus examination revealed no pathological finding in the right eye. Whereas calcified plaque was seen in upper arquat artery bifurcation in the left eye. Pallorness with retinal edema was seen in this arterial trace. Retinal artery occlusion was diagnosed and patient was referred for hyperbaric oxygen therapy. After a total of 20 sessions of hyperbaric oxygen therapy, the calcified plaques disappeared and her BCVA increased to 20/20. Hyperbaric oxygen treatment is vision-saving method which should be considered in retinal artery occlusion.

  15. Abnormal origin of the ophthalmic artery from the anterior cerebral artery: Neuroradiological and intraoperative findings

    International Nuclear Information System (INIS)

    A 7-year old male child with an abnormal ophthalmic artery arising from the A1 segment of the anterior cerebral artery is described. The patient suffered growth inhibition which was thought to be caused by a craniobasal cystic lesion affecting the hypothalamus. Preoperative angiograms revealed no vascular abnormalities. The right ophthalmic artery, however, could not be identified. During resection of a large arachnoid cyst the ophthalmic artery was found to arise from the A1 segment of the anterior cerebral artery. To the best of our knowledge, this exact anomaly has not previously been reported. The clinical, neuroradiological and intraoperative findings are presented. (orig.)

    The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

    Experimental rats with root avulsion of the brachial plexus upper trunk were treated with the improved C3-4 transfer for neurotization of C5-6. Results showed that Terzis grooming test scores were significantly increased at 6 months after treatment, the latency of C5-6 motor evoked potential was gradually shortened, and the amplitude was gradually increased. The rate of C3 instead of C5 and the C4 + phrenic nerve instead of C6 myelinated nerve fibers crossing through the anastomotic stoma was approximately 80%. Myelinated nerve fibers were arranged loosely but the thickness of the myelin sheath was similar to that of the healthy side. In clinical applications,39 patients with root avulsion of the brachial plexus upper trunk were followed for 6 months to 4.5 years after treatment using the improved C3 instead of C5 nerve root transfer and C4 nerve root and phrenic nerve instead of C6 nerve root transfer. Results showed that the strength of the brachial biceps and deltoid muscles recovered to level III-IV, scapular muscle to level III-IV, latissimus dorsi and pectoralis major muscles to above level III, and the brachial triceps muscle to level 0-III. Results showed that the improved C3-4 transfer for root avulsion of the brachial plexus upper trunk in animal models is similar to clinical findings and that C3-4 and the phrenic nerve transfer for neurotization of C5-6 can innervate the avulsed brachial plexus upper trunk and promote the recovery of nerve function in the upper extremity.

    Coronary arteries have been extensively described and recognized by gross anatomic studies. However, in the clinical setting, the recognition of the conal artery is essential during coronary angiography, as well as certain congenital heart conditions such as tetralogy of Fallot. In order to provide a complete anatomic and physiologic correlation of the actual incidence and distribution of the conal artery we examined 300 formalin fixed hearts with gross dissections and 300 coronary angiograms. The conal artery was identified in all hearts examined and five main patterns were recognized. In Type A (193, 32.1%), the conal artery arose as a branch of the right coronary artery (RCA); in Type B (96, 16%), the conal artery arose from the common coronary ostium with the RCA; in Type C (242, 40.3%), the conal artery took origin from the right aortic sinus as an independent artery; in Type D (48, 8%), multiple conal arteries were present and arose from the RCA as separate branches (32, 66.6%), from a common ostium with the RCA (8, 16.6%) or from the aortic sinus (8, 16.6%); in Type E (22, 3.6%), the conal artery arose as a branch of the right ventricular branch (17, 2.8%) or acute marginal artery (5, 0.8%). The relative prevalence of the five patterns as well as the morphology and the topography of the conal artery varied significantly with the degree of coronary luminal stenosis (as observed during angiography) and also with the degree of hypertrophied ventricular wall (as observed during gross dissections).

    Cranial nerve dysfunction, obstruction hydrocephalus, signs of brain stem dysfunction, and signs of a space-occupying lesion in the posterior fossa are presumed to be related to a megadolicho basilar artery, if present. Since there are no large series of patients with such vascular anomaly, a bias in relating symptoms with the presence of a megadolicho basilar artery is not excluded. We therefore studied retrospectively the incidence of megadolicho and dolicho basilar artery on cranial CT-scan of 3332 patients of 50 years and older. Patient records were reviewed for the above mentioned symptoms. 12 out of 22 patients with a megadolicho basilar artery and 2 patients out of 40 with a dolicho basilar artery had one or two of these symptoms. It is concluded that a megadolicho basilar artery can cause cranial nerve dysfunction, obstruction hydrocephalus, signs of brain stem dysfunction, and signs of a space-occupying lesion in the posterior fossa.

    The trigeminal artery is one of four primitive anastomoses between the internal carotid artery and vertebrobasilar system that regresses in the sixth week of fetal development. A persistent trigeminal artery (PTA) is generally an incidental finding but may also be associated with intracranial vascular pathologies such as aneurysms, arteriovenous malformations, and cranial nerve compression syndromes. We present an extremely rare case of a right PTA with an associated bleeding fusiform aneurysm located in the carotidian (lateral) part of the PTA. In addition, this rare anatomic variation was associated with bilateral absence of the posterior communicating arteries, a left posterior cerebral artery originating from the left internal carotid artery, and agenesis of the A1 segment of the left anterior cerebral artery.

    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

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

    to analyze the implications of tooth reimplantation after traumatic avulsion in patients requiring orthodontic treatment. CONCLUSIONS: Tooth movement of a reimplanted tooth after traumatic avulsion is viable provided no signs of abnormality are present. Ankylosed teeth, however, are not amenable to orthodontic movement but should be preserved as space maintainers until root resorption is completed, provided that the teeth do not present with severe infraocclusion. Should an ankylosed tooth be in severe infraocclusion, crown amputation and root burial are indicated as a means to preserve the alveolar bone in the region, since resorption will occur by replacement of the buried root, as was the case in this report.

    Continuous intra-arterial blood gas monitoring is a potentially valuable tool in the surgical and intensive care arenas. Patient oxygenation and acid base status can change rapidly and without warning. The ability to monitor pHa, PaCO2 and PaO2 in arterial blood will be a major medical advance for the anesthesiologist and intensivist. Intra-arterial blood gas sensors are typically placed in radial arteries. In certain patient populations accurate monitoring is not possible in radial arteries due to arterial environmental factors such as hypotension, vasoconstriction and atherosclerotic disease. These same factors can make radial cannulation difficult resulting in traumatic catheter insertion, thereby further compromising flow conditions. In situations where radial artery flow is expected to be compromised, selecting a large vessel for sensor placement is desirable. We report an initial feasibility study of our blood gas monitoring system using the femoral artery as the sensing site. Clinical results are presented as well as potential advantages and disadvantages associated with monitoring in the femoral artery.

    2016-07-01

    Full Text Available Background: Extensor mechanism failure secondary to knee replacement could be due to tibial tubercle avulsion, Patellar tendon rupture, patellar fracture or quadriceps tendon rupture. An incidence of Patella tendon rupture of 0.17% and Quadriceps tendon rupture of around 0.1% has been reported after Total knee arthroplasty. These are considered a devastating complication that substantially affects the clinical results and are challenging situations to treat with surgery being the mainstay of the treatment. Case Description: We report here an interesting case of a patellar tendon rupture of one knee and Quadriceps tendon rupture of the contralateral knee following simultaneous bilateral knee replacement in a case of inflammatory arthritis patient. End to end repair for Quadriceps tear and augmentation with Autologous Hamstring tendon graft was done for Patella tendon rupture. OUTCOME: Patient was followed up for a period of 1 year and there was no Extension lag with a flexion of 100 degrees in both the knees. DISCUSSION: The key learning points and important aspects of diagnosing these injuries early and the management techniques are described in this unique case of bilateral extensor mechanism disruption following knee replacements.

    Summary A 32-year-old woman hospitalized for subarachnoid hemorrhage showed rare arterial variation on the right side with anomalous origins of the vertebral artery, aberrant subclavian artery and persistent trigeminal artery. Angiography showed the right vertebral artery to originate from the right common carotid artery, the right subclavian artery to arise separately from the descending aorta, and persistent trigeminal artery on the right side. The possible embryonic mechanism of this previously unreported variant combination is discussed. PMID:22005696

  10. Goldenhar Syndrome Associated with Extensive Arterial Malformations

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined. We present a 7-month-old infant with intermittent respiratory distress that did not improve with respiratory interventions. Echocardiogram suggested a double aortic arch. Cardiac CT angiogram confirmed a right arch and aberrant, stenotic left subclavian artery, dilation of the main pulmonary artery, and agenesis of the left thyroid lobe. Repeat echocardiograms were concerning for severely dilated coronary arteries. Given dilation, a rheumatologic workup ensued, only identifying few weakly positive autoantibodies. Further imaging demonstrated narrowing of the aorta below the renal arteries and extending into the common iliac arteries and proximal femoral arteries. Given a physical exam devoid of rheumatologic findings, only weakly positive autoantibodies, normal inflammatory markers, and presence of the coronary artery dilation, the peripheral artery narrowings were not thought to be vasculitic. This case illustrates the need to identify definitive anomalies related to Goldenhar Syndrome. Although this infant’s presentation is rare, recognition of specific vascular findings will help differentiate Goldenhar Syndrome from other disease processes.

  14. Duplication of hepatic artery

    Directory of Open Access Journals (Sweden)

    2001-01-01

    Full Text Available Background: The hepatic arterial anatomy is aberrant in almost 33-41% of individuals. The variant arterial anatomy recognized during routine cadaveric dissection offers great learning potential. Such findings provide an alternative perspective to view common morphology and its structural and functional importance. These impart the concept of patient individuality and subsequent individualization of medical and surgical therapies. Adequate knowledge of normal and abnormal arterial anatomy is essential for peripancreatic surgery and liver transplantation. Aims of the study: To report on hepatic artery variations observed in the dissecting room and to find out the macroscopic pattern of varied human hepatic arterial vascularization by cadaveric dissection. Patients and Methods: Twenty human cadavers of caucasian origin were dissected to study the source and topographic pattern of hepatic arterial supply. Results: Nineteen cadavers exhibited typical hepatic arterial supply from the celiac axis. Only one female body out of twenty cadavers exhibited a dual arterial supply to all parts of liver and gallbladder. One artery originated from the celiac axis whereas the other was given off by the superior mesenteric artery. Conclusion: No doubt, aberrant hepatic vascularization should be assessed preoperatively by invasive and noninvasive techniques to avoid fatal complications, but we favour careful dissection over angiography as a means of defining the arterial anatomy.

    2016-01-01

    This article reviews in detail the superficial brachiomedian artery (arteria brachiomediana superficialis), a very rare variant of the main arterial trunks of the upper limb. It branches either from the axillary artery or the brachial artery, descends superficially in the arm (similar to the course of the superficial brachial artery) and continues across the cubital fossa, runs superficially in the forearm, approaches the median nerve and enters the carpal canal to reach the hand. It usually terminates in the superficial palmar arch. The first drawing was published, in 1830, and the first description was published, in 1844. Altogether, to our knowledge, only 31 cases of a true, superficial brachiomedian artery have been reported (Some cases are incorrectly reported as superficial brachioradiomedian artery or superficial brachioulnomedian artery). Based on a meta-analysis of known, available studies, the incidence is 0.23% in Caucasians and 1.48% in Mongolians. Knowing whether or not this arterial variant is present is important in clinical medicine and relevant for: The catheterization via the radial or ulnar artery; harvesting the vascular pedicle for a forearm flap based on the radial, ulnar or superficial brachiomedian arteries; the possible collateral circulation in cases of the arterial closure; and the surgical management of carpal tunnel syndrome. Its presence can elevate the danger of an injury to the superficially located variant artery or of an accidental injection. PMID:27131025

    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

    Channel avulsion during fan development controls distribution and deposition of channel sandbodies and hence alluvial architecture of a fan system. Variable scale spatio-temporal information of fluvial responses to past climate changes is stored in these channel sandbodies. Further these channel sandbodies form fluvial aquifers in alluvial fans and therefore understanding of alluvial architecture and stratigraphy of a fan is crucial for development of groundwater management strategies. In this study we used multiple approaches to map subsurface fluvial aquifer architecture and alluvial stratigraphy, and to estimate sediment provenance using U-Pb dating of detrital zircon grains of Sutlej-Yamuna fan system in northwest India. Satellite imagery based geomorphic mapping shows two large fan system with interfan area. The fan surfaces show presence of major and minor paleochannels. 2D resistivity tomography along several transects across fan surfaces shows distinct layers with contrasting resistivity values. These geo-electric facies corresponds to presence of channel sandbodies beneath surface signature of paleochannels and finer floodplain deposits useful to demarcate lateral extent of subsurface channel sandbodies. A more detailed subsurface stratigraphy using ~50m deep sediment cores and their luminescence ages from across fan surface shows presence of multi-storey sandbodies (MSB) separated by floodplain fines. Within the MSB, individual channel deposits are identified by presence of channel scour surfaces located at coarse sand overlying fine sand layer. Depositional ages of MSB's ranges from ~81 ka (late MIS5) to ~15 ka (MIS2) with major depositional break during MIS3 in parts of the fans. Sediment aggradation rate varies laterally across fan surface as well as vertically down the depth with an average rate of 0.54 mm/year. Fluvial channel persistence for studied time interval (about last 81 ka BP) shows major depositional breaks (and possible incision) at ~41 ka

    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

    2011-01-01

    The beating heart creates blood pressure and flow pulsations that propagate as waves through the arterial tree that are reflected at transitions in arterial geometry and elasticity. Waves carry information about the matter in which they propagate. Therefore, modeling of arterial wave propagation extends our knowledge about the functioning of the cardiovascular system and provides a means to diagnose disorders and predict the outcome of medical interventions. In this review we focus on the physical and mathematical modeling of pulse wave propagation, based on general fluid dynamical principles. In addition we present potential applications in cardiovascular research and clinical practice. Models of short- and long-term adaptation of the arterial system and methods that deal with uncertainties in personalized model parameters and boundary conditions are briefly discussed, as they are believed to be major topics for further study and will boost the significance of arterial pulse wave modeling even more.

    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

    Objective: To observe the presentation and variation of extrahepatic branches originating from hepatic artery by hepatic arteriography.Methods: Hepatic arteriogram of 200 cases with unresectable hepatic primary or metastatic tumors before interventional therapy were retrospectively analyzed. Two interventional radiologists independently reviewed the type, originating artery, distribution and variation of extrahepatic artery.Results: Five types of extrahepatic artery were found, with the most common type of the right gastric artery (n=156, 78%), followed by the cystic artery (n=126, 63%), accessory left gastric artery (n=19, 9.5%), hepatic falciform artery (n=5, 2.5%), and accessory left inferior phrenic artery (n=4, 2%). In 188 cases, there were extrahepatic arteries derived from hepatic proper artery or its branches, and the most frequent originating site was the right hepatic artery (130 extrahepatic branches), followed by the proper hepatic artery (103 branches), left hepatic artery (56 branches) and middle hepatic artery (3 branches). The left hepatic artery was the arising site with the multiple types of extrahepatic branches including all above branches except the cystic artery.Conclusion: Many types of extrahepatic branches usually derive from the hepatic artery or its distal branches, and its originating sites are not constant. It is important to avoid damage of extrahepatic tissue during interventional therapy for liver tumors.

    Background At present, revascularization is still one of the most critical technologies in orthotopic liver transplantation (OLT). Hepatic artery (HA) variations occur frequently in both donors and recipients. Moreover, there are always some pathological changes in the recipient hepatic artery. If handled improperly, it may cause complications after anastomosis.Therefore, arterial conduit could be used in primary OLT, re-OLT and multiple-OLT. This study aimed to investigate the indications, methods and techniques with usage of arterial conduit for HA revascularization during adult OLT.Methods We reviewed 1200 patients of consecutive OLTs performed during 2000-2009 in the First Affiliated Hospital of Sun Yat-sen University. Of these patients, 48 recipients with artery variations received HA revascularization with usage of arterial conduit and special postoperative managements. The indications, methods, techniques, and the managements of postoperative complications in adult OLT with usage of arterial conduit for HA revascularization were analyzed.Results In 48 cases with artery bypass, the arterial conduit were anastomosed between donor hepatic artery and recipient infrarenal aorta (n=32), between donor hepatic artery and recipient suprarenal aorta (n=10), and between donor upper abdominal organ cluster artery and recipient suprarenal aorta (n=6). The technique was applied in 4% (48/1200 cases) of the whole OLTs performed in the same period, and the patency rate of the conduits was 100%. Forty patients (83.3%) survived, and the average survival time was 3.9 years. Eight patients (16.7%) died (all due to tumor recurrence),while the average survival time was 1.2 years. All these patients have not experienced artery-related complications in their survival time.Conclusions When recipient HA has variations or pathological changes in OLT, the donor artery should be anastomosed to recipient abdominal aorta with an arterial conduit to achieve satisfactory outcomes

  14. Circle of Willis variant analogous to fetal type primitive trigeminal artery

    International Nuclear Information System (INIS)

    Primitive caroticobasilar anastomoses are uncommon embryonic arterial connections between the carotid (anterior) and vertebrobasilar (posterior) circulations. With the exception of extracranial proatlantal intersegmental arteries, these embryonic arterial anastomoses are named according to the cranial nerves which they parallel. In this report, a previously undescribed variant circle of Willis with supraclinoid caroticobasilar anastomosis, functionally equivalent to a fetal type primitive trigeminal artery, is presented.

    Celiac artery compression syndrome, also called median arcuate ligament compression syndrome, causes gastrointestinal ischemia secondary to compression of the proximal portion of the celiac artery just beyond its origin by the median arcuate ligament of the diaphragm. This syndrome is frequently demonstrated on aortography performed in patients without complaints of intestinal angina. Isolated stenosis or even occlusion of the celiac artery is always compensated for by collateral circul...

    A three-dimensional multilayer model of mechanical response for analyzing the effect of pressure on arterial failure is presented in this work. The multilayer arterial wall is considered to be composed of five different layers. The three-dimensional effects are incorporated within the five-concentric axisymmetric layers while incorporating the nonlinear elastic characteristics under combined extension and inflation. Constitutive equations for fiber-reinforced material are employed for three of the major layers, i.e., intima, media and adventitia and an isotropic material model is employed for the other two layers, i.e., endothelium and internal elastic lamina. Our own developed three-dimensional five-layer model has been utilized to model propagated rupture area of the arterial wall. Required parameters for each layer are obtained by using a nonlinear least square method fitted to in vivo non-invasive experimental data of human artery and the effects of pressure on arterial failure are examined. The solutions from our computational model are compared with previous studies and good agreements are observed. Local stresses and strain distributions across the deformed arterial wall are illustrated and consequently the rupture area is predicted by varying luminal pressure in the physiological range and beyond. The effects of pressure on the arterial failure have been interpreted based on this comprehensive three-dimensional five-layer arterial wall model. This is the first study which employs two constitutive equations and incorporates a five-layer arterial wall model in three-dimensions based on in vivo non-invasive experimental data for a human artery.

  17. Aneurysm of the superficial femoral artery in an infant

    International Nuclear Information System (INIS)

    An isolated arterial aneurysm in childhood is extremely rare. We report a 1-year-old girl with an aneurysm of the right superficial femoral artery, presenting as an asymptomatic mass of the thigh. The aneurysm involved the whole superficial femoral artery (9 cm in length), and surgical treatment would have required replacement of the affected artery. Conservative treatment was chosen, influenced by the patient's rapid growth at that time. Non-invasive, 3-D contrast-enhanced magnetic resonance angiography (MRA) was useful as an alternative to conventional angiography for detailed evaluation of the femoral arteries, including the aneurysm.

    Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed tomographic angiography and magnetic resonance angiography are constantly improving and are playing an increasingly important role in diagnosing vertebral artery pathology in clinical practice. This paper reviews the current state of vertebral artery imaging from an evidence-based perspective. Normal anatomy, normal variants and a number of pathological entities such as vertebral atherosclerosis, arterial dissection, arteriovenous fistula, subclavian steal syndrome and vertebrobasilar dolichoectasia are discussed.

    Full Text Available The variation in origin of the testicular artery is not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. The renal artery is known to exhibit variations in its number and position. The knowledge of this variation will help the radiologists and surgeons in avoiding clinical complication during interventions. During routine dissection teaching to first year MBBS students at Sapthagiri Medical College, Bangalore we found variation in vascular pattern of testicular and renal artery associated with renal cyst. Photographs of the variations were taken. There was high origin of left testicular artery and accessory left renal artery associated with bilateral simple renal cyst in adult Male cadaver aged around 60years.There was also prehilar division of right renal artery associated with renal cyst. Anomalies in the origin, course and number of testicular artery were observed in 4.7 percent of cases. Additional renal vessels are known as the accessory renal artery and their incidence varies between 9-76%. In the present case there was high origin of left testicular artery associated with accessory renal artery and renal cyst. This anatomical knowledge of the presence of accessory renal artery and high origin of testicular artery in this case is important for radiologists, surgeons and urologist in their clinical practice.

    Full Text Available Background. Hemobilia is a rare, jeopardizing complication of laparoscopic cholecystectomy coming upon usually within 4 weeks after surgery. The first-line management is angiographic coil embolization of hepatic arteries, which is successful in the majority of bleedings: in a minority of cases, a second embolization or even laparotomy is needed. Case Presentation. We describe the case history of a patient in which laparoscopic cholecystectomy was complicated 3 weeks later by massive hemobilia. The cause of haemorrhage was a pseudoaneurysm of a right hepatic artery branching off the superior mesenteric artery; this complication was successfully managed by one-stage angiographic embolization with full recovery of the patient.

    2008-12-01

    Geoarchaeological research was performed to reconstruct the floodplain history in the surroundings of two ancient Mesopotamian cities: Tell ed-Dēr and Sippar. The mapping of the floodplain is based on facies analyses of the sedimentary succession of 225 hand-operated boreholes. The archaeological sites Tell ed-Dēr and Sippar are closely linked to a palaeochannelbelt of the Euphrates, located in the western part of the study area. Channel activity started at least in ca 3100 BC/5050 cal BP, until ca 1400-1000 BC/3350-2950 cal BP. The channel belt was part of an avulsion driven multiple Euphrates channel network that gradually became abandoned from the second half of the 2nd millennium BC. A second mapped Euphrates, Tigris or Joint Euphrates -Tigris palaeochannel belt became abandoned well before 3100 BC. Examples of natural processes as well as human interactions triggering avulsion are given. Moreover, textual, archaeological and geological data show clearly that flood-control techniques and the construction of large-scale dikes seemed to be a common practice.

    The mineralogy and geochemistry of sands were investigated in the Nandu and Wanquan rivers, Hainan Island, China, to determine the history of avulsion in the lower reaches of the Nandu River. The study also provided the opportunity to assess the utility of geochemical analysis of sands as a provenance tool. Much of the heavy mineral fraction in the rivers consists of subangular Fe-Ti oxide and Fe-(hydr)oxide minerals, and less stable minerals such as amphibole, epidote, and andalusite, whereas rounded resistant ilmenite, rutile, tourmaline and zircon predominate on the deltaic coast. Mineral assemblage and chemical composition of individual samples are related to specific source areas and river tributaries. The results demonstrate northwestwards flow of the Nandu River during the mid-Holocene and earlier avulsion of the river to the northeast coast, probably during a Late Pleistocene marine highstand. Minor basement tilting, producing little relief, was sufficient to divert the lower reaches of rivers, and this effect was enhanced where basalt flows dammed former river courses. Bulk sample REE geochemistry is largely controlled by the relative abundance of monazite, allanite, titanite, zircon and epidote, derived principally from granites. Detrital geochemistry alone shows too much variability to interpret provenance. However, a smaller number of heavy mineral analyses provide an understanding of the mineralogical origins of geochemical variation, thus enabling interpretations of provenance.

    The subclavian-vertebral artery steal syndrome (SSS) is the hemodynamic phenomenon of blood flow reversal in the vertebral artery due to significant stenosis or occlusion of the proximal subclavian artery or the innominate artery. Occasionally, SSS is diagnosed in patients not harboring arterial stenosis. With the exception of arterial congenital malformations, the limited case reports of SSS with intact subclavian artery are attributed to dialysis arteriovenous fistulas (AVFs). Interestingly, these cases are more frequently symptomatic than those with the classical atherosclerotic SSS forms. On the other hand, the disclosure of SSS due to subclavian/innominate artery atherosclerotic stenosis, even in the absence of accompanying symptoms, should prompt a thorough cardiovascular work-up for the early detection of coexisting coronary, carotid, or peripheral artery disease. Herein, we review the incidence, clinical presentation, sonographic findings, and therapeutic interventions related to SSS with and without subclavian/innominate artery stenosis. We also review the currently available data in the literature regarding the association of SSS and dialysis AVF. In addition, we present a patient with bilateral symptomatic SSS as the result of an arteriovenous graft (AVG) that was introduced after the preexisting AVF in the contralateral arm became nonfunctional. SSS due to subclavian or innominate artery stenosis/occlusion is rarely symptomatic warranting interventional treatment. In contrast, when it is attributed to AVF, surgical correction is frequently necessary. PMID:27301069

  7. Arterial Stiffness and Dialysis Calcium Concentration

    Directory of Open Access Journals (Sweden)

    Fabrice Mac-Way

    2011-01-01

    Full Text Available Arterial stiffness is the major determinant of isolated systolic hypertension and increased pulse pressure. Aortic stiffness is also associated with increased cardiovascular morbidity and mortality in patients with chronic kidney disease, hypertension, and general population. Hemodynamically, arterial stiffness results in earlier aortic pulse wave reflection leading to increased cardiac workload and decreased myocardial perfusion. Although the clinical consequence of aortic stiffness has been clearly established, its pathophysiology in various clinical conditions still remains poorly understood. The aim of the present paper is to review the studies that have looked at the impact of dialysis calcium concentration on arterial stiffness. Overall, the results of small short-term studies suggest that higher dialysis calcium is associated with a transient but significant increase in arterial stiffness. This calcium dependant increase in arterial stiffness is potentially explained by increased vascular smooth muscle tone of the conduit arteries and is not solely explained by changes in mean blood pressure. However, the optimal DCa remains to be determined, and long term studies are required to evaluate its impact on the progression of arterial stiffness.

    Full Text Available INTRODUCTION: Renal transplantation with multiple arteries appears, in literature, associated to a major index of surgical complications. This study compared the surgical complications and short-term outcome renal transplants with multiple arteries and single artery grafts. MATERIALS AND METHODS: The data of 64 renal transplants with multiple arteries performed between January 1995 and December 1999 were compared to the ones of 292 transplants with single renal artery. The aspects analyzed were number of arteries of the graft, donor type, vascular reconstruction technique, the occurrence of surgical complications, the incidence of delayed graft function, graft function 1 month after transplantation, graft loss and the patients' deaths. RESULTS: The incidence of surgical complications in grafts with multiple arteries and single renal artery was respectively: vascular - 3.1% and 3.1%; urological - 6.3% and 2.7% and other surgical complications - 15.6% and 10.6%, respectively. The incidence of lymphoceles was 3.1% in grafts with a single artery and 12.5% in grafts with more than 1 artery (p = 0.0015. The incidence of delayed graft function in grafts with multiple arteries and with a single renal artery was respectively 35.1 and 29.1% (p = 0.295. Mean serum creatinine at the 30th postoperative day was 2.46 and 1.81 in grafts with multiple and with 1 artery, respectively (p=0.271. CONCLUSIONS: Kidney transplantation using grafts with single and multiple arteries present similar indexes of surgical complications and short-term outcome; lymphoceles were more frequent among grafts with multiple arteries.

    Innominate artery injury is a rare, but catastrophic complication of tracheostomy. We present a case of severe hemorrhagic shock in a 79-year-old male with innominate artery injury that occurred during tracheostomy. Despite temporary innominate artery isolation, the regional forehead saturation was 60 % without laterality. Because adequate cerebral blood flow was apparently maintained through collateral flow, we ligated the innominate, right carotid, and subclavian arteries. We confirmed adequate blood flow to the brain and the right subclavian artery through collateral circulation after ligation using computed tomographic angiography. A damage control management, which involves ligating the injured innominate artery to arrest hemorrhage and monitoring regional forehead saturation for brain ischemia, can be a considerable procedure for the treatment of severe hemorrhagic shock due to innominate artery injury.

  10. Partial subclavian steal syndrome in a congenitally anomalous subclavian artery

    International Nuclear Information System (INIS)

    Background. A subclavian steal syndrome results from the abnormal flow of blood due to the occlusion in the subclavian artery proximal to the origin of the vertebral artery. A case of a male patient with a partial subclavian steal syndrome is presented. Case report. The syndrome was caused by a stenotic lesion of an aberrant right subclavian artery (the so called lusorian artery). The partial subclavian steal was recognized using the duplex ultrasound which showed the to and fro pattern in the right vertebral artery. Angiography of the aortic arch revealed the arterial anomaly. In our case, duplex ultrasound was a crucial method in diagnosing the partial subclavian steal syndrome. However, in order to show the arterial anomaly, the final evaluation had to be performed using arteriography. Conclusions. The early recognized partial subclavian steal syndrome provides good understanding of patient's symptoms, successful follow up, and a variety of treatment options. (author)

  11. ARTERIAL STIFFNESS AND CHRONIC KIDNEY DISEASE: CAUSES AND CONSEQUENCES

    Directory of Open Access Journals (Sweden)

    J. D. Kobalava

    2015-09-01

    Full Text Available Chronic kidney disease (CKD is associated with increased cardiovascular risk. CKD is characterized by accelerated aging of vessels in which the age-related arterial stiffness increase is exacerbated by a number of uremia-related processes. Increased arterial stiffness is associated with structural and functional disorders, as well as with the increase in cardiovascular mortality in patients with CKD. Increased arterial stiffness is diagnosed at an early stage of CKD. Modern understanding of the mechanisms of increased risk of cardiovascular complications in CKD, the factors contributing to the loss of elasticity of the arteries, arterial stiffness increase consequences are analyzed. Data illustrating the twoway interaction between CKD and arterial stiffness and mechanisms of accelerated progression of arterial stiffness in CKD are presented.

    Full Text Available Abstract Background The superiority of a single stage combined anterior (first posterior (second approach and end-to-side side-to-side grafting neurorrhaphy in direct cord implantation was investigated as to providing adequate exposure to both the cervical cord and the brachial plexus, as to causing less tissue damage and as to being more extensible than current surgical approaches. Methods The front and back of the neck, the front and back of the chest up to the midline and the whole affected upper limb were sterilized while the patient was in the lateral position; the patient was next turned into the supine position, the plexus explored anteriorly and the grafts were placed; the patient was then turned again into the lateral position, and a posterior cervical laminectomy was done. The grafts were retrieved posteriorly and side grafted to the anterior cord. Using this approach, 5 patients suffering from complete traumatic brachial plexus palsy, 4 adults and 1 obstetric case were operated upon and followed up for 2 years. 2 were C5,6 ruptures and C7,8T1 avulsions. 3 were C5,6,7,8T1 avulsions. C5,6 ruptures were grafted and all avulsions were cord implanted. Results Surgery in complete avulsions led to Grade 4 improvement in shoulder abduction/flexion and elbow flexion. Cocontractions occurred between the lateral deltoid and biceps on active shoulder abduction. No cocontractions occurred after surgery in C5,6 ruptures and C7,8T1 avulsions, muscle power improvement extended into the forearm and hand; pain disappeared. Limitations include spontaneous recovery despite MRI appearance of avulsions, fallacies in determining intraoperative avulsions (wrong diagnosis, wrong level; small sample size; no controls rule out superiority of this technique versus other direct cord reimplantation techniques or other neurotization procedures; intra- and interobserver variability in testing muscle power and cocontractions.

    Introduction: Anomalous origin of coronary arteries from opposite sinus of Valsalva is rare finding. The incidence of anomalous origination of the left coronary artery from right sinus is 0.15% and the right coronary artery from the left sinus is 0.92%. The ectopic origin of left coronary artery or right coronary artery from opposite sinus depending on pathways and considering atherosclerotic changes are manifested with different clinical significance. Case report: We report two cases, the first case the coronary angiography showed the left coronary artery arising from the right coronary sinus, presenting with proximally and distally stenosed left anterior descending artery (LAD), associated with medial and distal stenosed right coronary artery (RCA). The second case the coronary angiography revealed the right coronary artery arising from the left coronary sinus, associated with tortuous medial and distal segments of left anterior descending artery (LAD), without atherosclerotic changes. The first case successfully underwent treatment procedures based on guidelines for revascularization. Conclusion: The coronary angiography of patients with coronary ischemia determines atherosclerotic disease with possibility of the presence of coronary artery anomalies that in cases with ectopic origin from opposite sinus continues to exist as a challenge during treatment in interventional cardiology.

  5. STUDY ON VARIATIONS OF INFERIOR SEGMENTAL BRANCH OF RENAL ARTERY

    Directory of Open Access Journals (Sweden)

    Chandragirish S

    2014-11-01

    Full Text Available Background: The segmental arteries of the kidney supply the organ in such a way that, each renal pole receives its own artery while, the anterior portion between the poles is supplied by an upper and lower segmental vessel. These two arteries also include in their territory the lateral edge of the kidney and adjacent to the strip of parenchyma on the dorsal or posterior aspect of the organ. The knowledge of inferior segmental branch of renal artery is very important for surgeries in its distribution area in kidney. Materials and Methods: 100 kidneys (Fifty pairs intact with abdominal aorta were collected from department of Forensic medicine, JSS Medical College and Mysore Medical College. For study of segmental variation Corrosion cast technique method was used. The variations of inferior segmental branch of renal artery were observed and recorded. Results: In present study type I inferior segmental branch of renal artery were found in - 59% cases, type II in - 6% cases, type III in - 28% cases, type IV in - 2% cases. Conclusion: The inferior segmental artery from the anterior division of the renal artery is the commonest event –arising in 59%. This is Type I, the normal type. It arises from the renal artery (28% or from the posterior division (6% or from the aorta (2%. The knowledge of inferior segmental branch of renal artery helpful in kidney transplantation and renal surgery because these type of surgeries success mainly depends on arterial ligations.

  6. Transcatheter Splenic Artery Occlusion for Treatment of Splenic Artery Steal Syndrome After Orthotopic Liver Transplantation

    International Nuclear Information System (INIS)

    Purpose: To review some aspects of the problem of splenic artery steal syndrome as cause of ischemia in transplanted livers and treatment by selective splenic artery occlusion. Materials and Methods: Eleven liver transplant patients from a group of 350 patients, nine men and two women,ranging in age from 40 years to 61 years (mean 52 years), presented with biochemical evidences of liver ischemia and failure, ranging from one to 60 days following orthotopic liver transplantation. Diagnosis of splenic artery steal syndrome was suspected by elevated enzymes, Doppler ultrasound and confirmed by celiac angiogram. Patients with confirmed hepatic artery thrombosis before angiography were excluded from the study. Embolization with Gianturco coils was performed. Results: All patients were treated by splenic artery embolization with Gianturco coils. The 11 patients improved clinically within 24 hours of the procedure with significant change in the biochemical and clinical parameters. Followup ranged from one month to two years. One of the 11 patient initially improved, but developed hepatic artery thrombosis within 24 hours of the embolic treatment,requiring surgical repair. Conclusion: Splenicartery steal syndrome following liver transplantation surgery can be diagnosed by celiac angiography, and effectively treated by splenic artery embolization with coils. Embolization is one of the treatments available, it is minimally invasive, and leads to immediate clinical improvement. Hepatic artery thrombosis is a possible complication of the procedure

Based on the angiographic assessment of abdominal aorta and arteries of the lower extremities, patients with stenosis greater than 70% in the lower extremity arteries were included. A group of healthy individuals aged ≥50 years was recruited as a control. Risk factors for atherosclerosis including smoking, diabetes mellitus, hyperlipidemia, ischemic heart disease, and cerebrovascular disease were recorded. Common carotid arteries (CCAs and the origins of the internal and external arteries were scanned with B-mode ultrasonogaphy. Significant ICA stenosis, >70% ICA stenosis but less than near occlusion of the ICA, was diagnosed when the ICA/CCA peak systolic velocity ratio was ≥3.5.Results: Ninety-five patients, with a mean age of 58.52 ± 11.04 years, were studied.

  8. Long-term outcomes of internal carotid artery disease treated using radial artery graft

    International Nuclear Information System (INIS)

    Complex internal carotid artery disease presents a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict occurrence of ischemic complications after internal carotid artery ligation. The present study concerns long-term clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2007, we performed radial artery grafting followed immediately by parent artery occlusion in 20 sides of 19 patients with complex internal carotid arteries disease with follow-up for more than 36 months (5 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative MRI and MR angiography (MRA) every year to assess graft patency, ischemic complications, and de novo aneurysm. Another 20 carotid aneurysms with visual disturbance were assessed concerning outcome. Among 13 patients with cranial nerve (III and VI) disturbances, all dysfunctions were improved in cases treated within 8 months of onset to operation. On the other hand, patients with second cranial nerve disturbances were not improved in cases treated after 4 months of onset. No long-term complications were discovered with MRI and MRA. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Long-term safety is satisfactory, with no delayed complications such as graft stenosis, ischemic complications or de novo aneurysm formations in follow-up periods of more than 3 years. Good clinical outcome of cranial nerve palsy was achieved in patients treated within 8 months of onset for cranial nerve (CN) III and VI, and 4 of CN II palsy. (author)

  9. Treatment of complex internal carotid artery aneurysms using radial artery grafts. Surgical technique, perioperative complications, and results in 17 patients

    International Nuclear Information System (INIS)

    Complex giant or large internal carotid artery aneurysms present a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict the occurrence of ischemic complications after internal carotid artery ligation. The present study concerns surgical technique, complications, and clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2005, we performed radial artery grafting followed immediately by parent artery occlusion in 17 patients with giant or large complex intracranial carotid aneurysms (3 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative digital subtraction angiography to assess graft patency and aneurysm obliteration. All 17 aneurysms were excluded from the cerebral circulation, with all radial artery grafts patent. Among 4 patients with cranial nerve disturbances, dysfunction was temporary in 5; in the others, oculomotor nerve paresis persisted. No perioperative cerebral infarction occurred. Sensory aphasia reflecting cerebral contusions caused by temporal lobe retraction resolved within 2 months, as did hemiparesis from a postoperative epidural hematoma. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Graft patency and aneurysm thrombosis were achieved in all patients. Cranial nerve dysfunction (III, VI) caused by altered blood flow from the internal carotid artery after occlusion was the most common complication and typically was temporary. In our experience with these difficult aneurysms, not only clipping but also reconstruction of the internal carotid artery was required, especially for wide-necked symptomatic

  10. Angiography of renal artery with special reference to the blood supply of the kidney in camel

    International Nuclear Information System (INIS)

    The vascular system of kidney of the camel is strikingly different from that of other domestic animals. The right and left renal arteries emanated independently from the ventrolateral aspect of abdominal aorta behind cranial mesenteric artery at the level of cranial border of third and fourth lumbar vertebra respectively. The renal artery after short lateral course divided into medial and lateral lobar arteries before reaching the hilus. The lobar artery after entering into the hilus gave 9-11 interlobar arteries. These interlobar arteries at the corticomedullary junction formed 2 - 7 arcuate arteries. The arcuate arteries detached numerous straight branches from their convex surfaces and then ended by dividing into 2 - 4 terminal branches. The straight branches and the terminal branches were present in a radiating manner as interlobular arteries

    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.

  12. Atherosclerosis and the internal mammary arteries

    International Nuclear Information System (INIS)

    One hundred and fifty patients with coronary artery disease (CAD), 14 (9.3%) of whom had coexisting peripheral vascular disease, underwent bilateral internal mammary arteriography to study the incidence and extent of atherosclerosis in these vessels. Significant atherosclerosis of the internal mammary arteries (IMAs) was present in three patients (2%), of whom one had coexisting peripheral vascular disease. Lesions in the IMAs were found either proximally, close to the origin or distally, around the terminal bifurcation. Six of the 14 patients with peripheral vascular disease (4% of total subjects) had significant atherosclerosis of the brachiocephalic arteries. Atherosclerotic involvement of the IMA is very unusual and rarely interferes with the use of these vessels for coronary bypass. More common, however, is atherosclerosis of the subclavian arteries, a contraindication for IMA grafting if the lesion is proximal to the IMA origin. (orig.)

    Full Text Available Background and Objective: Popliteal artery injuries are uncommon in developed countries, but it may be common in our country and is associated with poor rates of limb salvage, as well as high levels of morbid-ity. The aim of the present study was to determine the causes of popliteal artery injuries. Materials and Methods: Twenty patients with pop-liteal artery injuries during 3.5 years were studied by angiography in Imam Khomeini Hospital of Tabriz. Results: There were 18 male and two female patients with a median age of 34/00±15/68 years (range 15 – 70 years. The most common cause of trauma in this study was traffic accidents and the most common in-jury was complete occlusion. Conclusion: Popliteal artery injuries are more com-mon in our country and the most common cause is blunt trauma, especially motorcycle accidents.

    1994-01-01

    Mineralogical investigations of calcifications located in coronary vessels were performed on the material obtained from the endarterectomized arteries of 18 patients (15 M, 3 F, aged 36-65) during surgical revascularization procedures consisting in coronary artery bypass grafting. The samples were tested using scanning microscopy, X-ray diffractometry, infrared spectroscopy, atomic absorption spectroscopy, electron microprobe and neutron activation spectroscopy. The results of analyses were calculated with the use of computer programmes. Two types of mineralization were determined: 1. secret mineralization identified as higher than normal content of elements in biological tissues, not demonstrating any mineral grains, and 2. apparent mineralization, appearing micro- and macroscopically as grains composed mainly of hydroxyapatite containing admixture of carbonate groups, i.e. a mineral identical with apatite present in bones, or as calcification of other tissues (heart valves, lungs etc.). The authors suggest that the phenomenon of mineralization should be taken into consideration in the preventive treatment of coronary atheriosclerosis. PMID:7808039

    Atherosclerosis, the narrowing of vessel diameter and build-up of plaques in coronary arteries, leads to an increase in the shear stresses present, which can be used as a physics-based trigger for targeted drug delivery. In order to develop appropriate nanometer-size containers, one has to know the morphology of the critical stenoses with isotropic micrometer resolution. Micro computed tomography in absorption and phase contrast mode provides the necessary spatial resolution and contrast. The present communication describes the pros and cons of the conventional and synchrotron radiation-based approaches in the visualization of diseased human and murine arteries. Using registered datasets, it also demonstrates that multi-modal imaging, including established histology, is even more powerful. The tomography data were evaluated with respect to cross-section, vessel radius and maximal constriction. The average cross-section of the diseased human artery (2.31 mm2) was almost an order of magnitude larger than the murine one (0.27 mm2), whereas the minimal radius differs only by a factor of two (0.51 mm versus 0.24 mm). The maximal constriction, however, was much larger for the human specimen (85% versus 49%). We could also show that a plastic model used for recent experiments in targeted drug delivery represents a very similar morphology, which is, for example, characterized by a maximal constriction of 82%. The tomography data build a sound basis for flow simulations, which allows for conclusions on shear stress distributions in stenosed blood vessels.

    Full Text Available Ancient schwannoma is a rare variant of neural tumors though rarely seen in the thorax. The combination with coronary artery diseases is also rare. Here we describe a 66 year-old male who had undergone one-stage combined surgery for thoracic ancient schwannomas removal and coronary artery disease. The masses were, respectively, 13 cm in the middle mediastinum and 5 cm in diameter originating from the intercostal nerve. The tumors were successfully removed using sternotomy, and then a coronary artery bypass grafting was performed. Here we discuss this rare tumor in relation to the relevant literature.

    Full Text Available Thumb pulp defects are commonly due to avulsion injuries. It is very important to reconstruct these defects using sensate flaps as the thumb pulp needs to be sensate for implementing the various functions of the thumb. A very good option for coverage of these defects is the islanded first dorsal metacarpal artery flap. Our study was done over a period of 2 years and involved 9 consecutive cases of thumb pulp defects treated at our institution. The patients included 8 males and 1 female, ranging in age from 16 to 51 years old. The flap size ranged from 2 x 1.5 cm to 5 x 3 cm. We had only one complication in the form of partial flap necrosis, which fortunately healed following debridement without the need for a secondary procedure. All our cases were done under local anesthesia with tourniquet control. All the patients had good fine touch and average two-point discrimination of 6 mm, which was satisfactory. Our good results further reinforce the islanded first dorsal metacarpal artery flap as one the best flaps for sensate reconstruction of thumb pulp defects. It replaces the soft tissue loss at the thumb pulp with minimal donor site morbidity and with good return of thumb pulp sensation.

    Hemodynamic parameters play an important role in aneurysm formation and growth. However, it is difficult to directly observe a rapidly growing de novo aneurysm in a patient. To investigate possible associations between hemodynamic parameters and the formation and growth of intracranial aneurysms, the present study constructed a computational model of a case with an internal carotid artery aneurysm and an anterior communicating artery aneurysm, based on the CT angiography findings of a patient. To simulate the formation of the anterior communicating artery aneurysm and the growth of the internal carotid artery aneurysm, we then constructed a model that virtually removed the anterior communicating artery aneurysm, and a further two models that also progressively decreased the size of the internal carotid artery aneurysm. Computational simulations of the fluid dynamics of the four models were performed under pulsatile flow conditions, and wall shear stress was compared among the different models. In the three aneurysm growth models, increasing size of the aneurysm was associated with an increased area of low wall shear stress, a significant decrease in wall shear stress at the dome of the aneurysm, and a significant change in the wall shear stress of the parent artery. The wall shear stress of the anterior communicating artery remained low, and was significantly lower than the wall shear stress at the bifurcation of the internal carotid artery or the bifurcation of the middle cerebral artery. After formation of the anterior communicating artery aneurysm, the wall shear stress at the dome of the internal carotid artery aneurysm increased significantly, and the wall shear stress in the upstream arteries also changed significantly. These findings indicate that low wall shear stress may be associated with the initiation and growth of aneurysms, and that aneurysm formation and growth may influence hemodynamic parameters in the local and adjacent arteries.

    The effects of vascular rarefaction (the loss of small arteries) on the circulation of blood are studied using a multiscale mathematical model that can predict blood flow and pressure in the systemic and pulmonary arteries. We augmented a model originally developed for the systemic arteries (Olufsen et al. 1998, 1999, 2000, 2004) to (a) predict flow and pressure in the pulmonary arteries, and (b) predict pressure propagation along the small arteries in the vascular beds. The systemic and pulmonary arteries are modelled as separate, bifurcating trees of compliant and tapering vessels. Each tree is divided into two parts representing the `large' and `small' arteries. Blood flow and pressure in the large arteries are predicted using a nonlinear cross-sectional area-averaged model for a Newtonian fluid in an elastic tube with inflow obtained from magnetic resonance measurements. Each terminal vessel within the network of the large arteries is coupled to a vascular bed of small `resistance' arteries, which are modelled as asymmetric structured trees with specified area and asymmetry ratios between the parent and daughter arteries. For the systemic circulation, each structured tree represents a specific vascular bed corresponding to major organs and limbs. For the pulmonary circulation, there are four vascular beds supplied by the interlobar arteries. This manuscript presents the first theoretical calculations of the propagation of the pressure and flow waves along systemic and pulmonary large and small arteries. Results for all networks were in agreement with published observations. Two studies were done with this model. First, we showed how rarefaction can be modelled by pruning the tree of arteries in the microvascular system. This was done by modulating parameters used for designing the structured trees. Results showed that rarefaction leads to increased mean and decreased pulse pressure in the large arteries. Second, we investigated the impact of decreasing vessel

    Full Text Available Identification of the origin of the central retinal artery (CRA is imperative in tailoring angiographic studies to resolve a given clinical problem. A case with dual ophthalmic arteries (OAs, characterized by different origins and distinct branching patterns, is documented for training purposes. Pre-clinical diagnosis of a 9-year-old child who presented with a sharp wire in the left-side eyeball was primarily corneal laceration. For imaging, a selected six-vessel angiographic study with the transfemoral approach was performed. Embolization was not required and the wire could be successfully removed. Right-side OA anatomy was normal, while left-side dual OAs with external carotid artery (ECA and internal carotid artery (ICA origins were seen. The case presented with a left-side meningo-ophthalmic artery (M-OA anomaly via the ECA, marked by a middle meningeal artery (MMA (origin: Maxillary artery; course: Through foramen spinosum with normal branches (i.e. anterior and posterior branches, and an OA variant (course: Through superior orbital fissure with a distinct orbital branching pattern. A smaller OA (origin: ICA; course: Through optic foramen with a distinct ocular branching pattern presented with the central retinal artery (CRA. The presence of the dual OAs and the M-OA anomaly can be explained by disturbed evolutionary changes of the primitive OA and stapedial artery during development. The surgical interventionist must be aware of dual OAs and M-OA anomalies with branching pattern variations on retinal supply, because of dangerous extracranial-intracranial anastomotic connections. It is of clinical significance that the origin of the CRA from the ICA or ECA must be determined to avoid complications to the vision.

    Full Text Available Among patients with coronary artery disease, left coronary artery (LMCA stenosis is the dangerous form of coronary arterial involvement, associated with increased mortality and morbidity unless immediate intervention is done. The gold standard treatment for left main coronary artery (LMCA stenosis is the emergency coronary artery bypass grafting to its branches, left anterior descending artery (LAD, and left circumflex artery (LCX. Of percutaneous intervention in the form of angioplasty and stenting of left main coronary artery are increasingly done. The anatomy and the site of stenosi s in the left main coronary artery determine the management option. In this context, the involvement of left main coronary artery and its anatomical pattern are important in deciding management options. AIM: To study the angiographic profile of significant Left main coronary artery (LMCA stenosis among the patients who underwent coronary angiography. METHODS: A total of 1911 cases of significant coronary arterial disease, who underwent coronary angiography a t King George Hospital, Visakhapatnam were studied in the present study and their coronary angiograms were analysed with respect to the pattern of involvement. RESULTS: of the 1911 cases of coronary artery disease, 118 patients have left main coronary arte ry disease. M/F ratio is 93/25. Of them 68.4% are hypertensive, 41.5 % are diabetics, 34.7% are smokers. Mean age of presentation was 59 yrs. Isolated LMCA involvement is seen in 5, associated with single vessel disease in 9, double vessel disease in 12 an d triple vessel diseases in 93. Ostio - proximal involvement is seen in 21, mid segment involvement in 13, distal – bifurcation involvement in 93 and total occlusion of LMCA in 1 case. CONCLUSION: Significant LMCA involvement is seen in 6.1%. In majority of c ases, it is associated with triple vessel disease and distal bifurcation is the commonest site involved.

    Renal artery embolism is not a rare occurrence, especially in patients with valvular heart disease, but the early diagnosis of this condition is infrequently accomplished. We report the clinical and laboratory data of 2 patients with valvular heart disease who presented with unilateral renal artery embolization. The usefulness of the determination of serum and urinary enzymes and renal function tests is discussed. We propose that these parameters support an earlier and more accurate diagnosis of renal artery embolism. PMID:2877758

    Objective: To summarize the experiences in endovascular stenting for vertebrobasilar artery stenosis, and to discuss its indications, technique, and perioperative management. Methods: Twenty cases presented with recurrent transient ischemic attack or with the history of infarction of posterior circulation territory. Thirteen cases complained of dizziness or headache. The locations of the stenoses were originated at vertebral artery in 13 cases, extracranial segment of vertebral artery in 3 cases, intracranial segment of vertebral artery in 5 cases, and basilar artery in 12 cases. All stenoses were more than 70% in diameter, with 2-12 mm in length. Balloon expended stents (BX, AVES670, EXPRESS, BIODIVESO) were introduced across the stenosis with the support of guide wire. Stents were deployed by inflation of the balloon slowly. Results: There were no procedural and periprocedural complications, and angiographic results showed that the stenoses returned to normal size in 29 cases, while reduced by more than 80% in 4 cases. The patients were asymptomatic and neurologically intact at the clinical follow-up for 3-10 months. Ten cases were followed by angiography, and there was no restenosis. Conclusion: Endovascular stenting for vertebrobasilar artery stenosis is effective and safe. But long-term results need further investigation

    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

  19. Analysis, reconstruction and manipulation using arterial snakes

    Man-made objects often consist of detailed and interleaving structures, which are created using cane, coils, metal wires, rods, etc. The delicate structures, although manufactured using simple procedures, are challenging to scan and reconstruct. We observe that such structures are inherently 1D, and hence are naturally represented using an arrangement of generating curves. We refer to the resultant surfaces as arterial surfaces. In this paper we approach for analyzing, reconstructing, and manipulating such arterial surfaces. The core of the algorithm is a novel deformable model, called arterial snake, that simultaneously captures the topology and geometry of the arterial objects. The recovered snakes produce a natural decomposition of the raw scans, with the decomposed parts often capturing meaningful object sections. We demonstrate the robustness of our algorithm on a variety of arterial objects corrupted with noise, outliers, and with large parts missing. We present a range of applications including reconstruction, topology repairing, and manipulation of arterial surfaces by directly controlling the underlying curve network and the associated sectional profiles, which are otherwise challenging to perform. © 2010 ACM.

    The objective was to investigate the effectiveness of cannabis-based medicines for treatment of chronic pain associated with brachial plexus root avulsion. This condition is an excellent human model of central neuropathic pain as it represents an unusually homogenous group in terms of anatomical location of injury, pain descriptions and patient demographics. Forty-eight patients with at least one avulsed root and baseline pain score of four or more on an 11-point ordinate scale participated in a randomised, double-blind, placebo-controlled, three period crossover study. All patients had intractable symptoms regardless of current analgesic therapy. Patients entered a baseline period of 2 weeks, followed by three, 2-week treatment periods during each of which they received one of three oromucosal spray preparations. These were placebo and two whole plant extracts of Cannabis sativa L.: GW-1000-02 (Sativex), containing Delta(9)tetrahydrocannabinol (THC):cannabidiol (CBD) in an approximate 1:1 ratio and GW-2000-02, containing primarily THC. The primary outcome measure was the mean pain severity score during the last 7 days of treatment. Secondary outcome measures included pain related quality of life assessments. The primary outcome measure failed to fall by the two points defined in our hypothesis. However, both this measure and measures of sleep showed statistically significant improvements. The study medications were generally well tolerated with the majority of adverse events, including intoxication type reactions, being mild to moderate in severity and resolving spontaneously. Studies of longer duration in neuropathic pain are required to confirm a clinically relevant, improvement in the treatment of this condition. PMID:15561385

    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.

  2. The study of an angiography technique on rat coronary arteries

    International Nuclear Information System (INIS)

    Experimental cardiology investigations carried out on rat hearts involve problems with the anatomy and physiology of the coronary arteries. Coronarography is an imaging method of the coronary arteries which can be performed intravitaly as well as postmortem. The aim of the study was to present our own radiological method of postmortem imaging of the rats coronary arteries. The investigation was done on anatomical preparations of the hearts of rats of the Sprague-DawleyR and WistarR strains. In total, 69 arteriograms were obtained. The coronary arteries were filled with contrast medium consisting of 60% barium sulfate and a 10% solution of gelatin in a proportion of 3:2. Images of contrasted arteries were presented on X-ray film and, in some groups of rats, by a digital image converter. X-rays were performed using an apparatus we designed ourselves. This enabled image fixing of the arteries during full rotation of the heart about its axis. The described method of contrasting and image presentation of the rat's coronary arteries was able to show consecutively the shape and topography of the arteries in a precise, spatial way in repeatable experiments. The authors demonstrated the existence of anatomical and topographic differences in the images of the investigated arteries in the rat compared with the human heart. They pointed out the presence of arterioarterial anastomoses. The authors suggest further research to gain a better understanding of the anatomy and physiology of the coronary circulation of the rat.

    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.

    Full Text Available Background: The basilar artery is the large median and major artery of the posterior circulation of the brain. Many variations are seen in the basilar artery, majority of them in position, origin and shape of the artery. Many authors have documented various anomalies as well as differences of the anatomy in this area in the Indian population as compared to the Western literature. Context and purpose of study: Many studies are available on the anterior circulation of the brain i.e. on vessels of the circle of Willis but studies on the posterior circulation are very few. And such studies so far had been done mostly in the American and European races and are mostly based on imaging techniques. Studies in the Indian population have been few. Hence the present study is concentrated on the morphological study of the basilar artery of human adult brain, to show the frequency and type of variations in the morphology of the basilar artery. Results: The basilar artery most commonly takes origin from the vertebral artery where left vertebral artery is greater in size than the right vertebral artery (72.5%. Level of formation of the basilar artery is most commonly observed at the ponto-medullary junction (62.5%. Length of the basilar artery varied from minimum 2.4cm to maximum 3.6cm. More commonly artery lies in the range of 2.6-3.0cm (57.5%. Diameter of the basilar artery at origin ranges from 3.2-4.2mm, at mid level from 3-4mm and at termination 3.1-4mm. Level of termination of the basilar artery is more commonly at the mid brain-pons junction (50%. Most of the basilar arteries are of straight type (55% and next common is bent or curved type (37.5%. Fenestration of 4mm is seen in proximal part of the one basilar artery (2.5%. Conclusion: Variations of the basilar artery are common. Neurosurgical importance of this study lies during the exposure of the region for different purposes. Knowledge of the vascular variations will increase the success of the

    This case report presents the robotically assisted multivessel minimally invasive direct coronary artery bypass grafting (MIDCAB) technique using the bilateral internal thoracic arteries. A 54-year-old man with multivessel coronary artery disease was considered eligible for a robotically assisted myocardial revascularization. The bilateral internal thoracic arteries were harvested completely in a totally skeletonized fashion through three 1-2-cm-long incisions on the left thoracic wall. A small left anterior thoracotomy was then performed. The left internal thoracic artery was anastomosed to the left anterior descending coronary artery, and the composite radial artery graft from the right internal thoracic artery was sequentially anastomosed to the first diagonal branch, the obtuse marginal branch, and the distal right coronary artery on the beating heart without cardiopulmonary bypass. The harvesting time of the grafts was 66 min, and the total operative time was 5 h 58 min. Postoperative angiography revealed that all grafts were widely patent. The postoperative course was uneventful, and the patient was discharged 10 days after the operation. Robotically assisted MIDCAB using the bilateral thoracic arteries is a safe and effective means of myocardial revascularization for patients with multivesssel disease. PMID:17721036

    Inhibitors of sodium-glucose cotransporter (SGLT)2 are a new class of oral drugs for type 2 diabetic patients that reduce plasma glucose levels by inhibiting renal glucose reabsorption. There is increasing evidence showing the beneficial effect of SGLT2 inhibitors on glucose control; however, less information is available regarding the impact of SGLT2 inhibitors on cardiovascular outcomes. The present study was designed to determine whether SGLT inhibitors regulate vascular relaxation in mouse pulmonary and coronary arteries. Phlorizin (a nonspecific SGLT inhibitor) and canagliflozin (a SGLT2-specific inhibitor) relaxed pulmonary arteries in a dose-dependent manner, but they had little or no effect on coronary arteries. Pretreatment with phlorizin or canagliflozin significantly inhibited sodium nitroprusside (SNP; a nitric oxide donor)-induced vascular relaxation in pulmonary arteries but not in coronary arteries. Phlorizin had no effect on cGMP-dependent relaxation in pulmonary arteries. SNP induced membrane hyperpolarization in human pulmonary artery smooth muscle cells, and pretreatment of cells with phlorizin and canagliflozin attenuated SNP-induced membrane hyperpolarization by decreasing K(+) activities induced by SNP. Contrary to the result observed in ex vivo experiments with SGLT inhibitors, SNP-dependent relaxation in pulmonary arteries was not altered by chronic administration of canagliflozin. On the other hand, canagliflozin administration significantly enhanced SNP-dependent relaxation in coronary arteries in diabetic mice. These data suggest that SGLT inhibitors differentially regulate vascular relaxation depending on the type of arteries, duration of the treatment, and health condition, such as diabetes.

    Full Text Available The extracranial internal carotid artery aneurysm (EICAA is an uncommon arterial lesion. Patients typically present with neurologic symptoms resulting from impaired cerebral perfusion and compression symptoms of cranial nerves. Often EICAA presents as a pulsatile neck mass, which is otherwise asymptomatic. We present a case of an 84-year-old female, who was initially referred to the Emergency Department for Otolaryngology with suspected peritonsillar abscess. The patient had a history of recent upper airway infection and cardiovascular comorbidities, including hypertension and ischaemic stroke complicated by extensive neurologic deficits. Physical examination revealed a compact, nonpulsatile mass in the lateral parapharyngeal space and local erythema of the mucosa. Duplex Doppler Ultrasonography and Computed Tomography revealed an atherosclerotic aneurysm of the right internal carotid artery, measuring 63×55×88 mm, stretching from the skull base to the angle of the mandible.

    Introduction Coronary artery atherosclerosis presents characteristic patterns of plaque distribution despite systemic exposure to risk factors. We hypothesized that local hemodynamic forces induced by the systolic compression of intramuscular septal perforators could be involved in atherosclerotic processes in the left anterior descending artery (LAD) adjacent to the septal perforators’ origin. Therefore we studied the spatial distribution of atherosclerosis in coronary arteries, especially i...

    A 15-year-old boy with transposition of the great arteries (TGA) and neonatal arterial switch operation (ASO) presented with complete occlusion of the left main coronary artery (LMCA). Intra-operatively, an intramural left coronary artery was identified. Therefore, since age 7 years he had a series of screening exercise stress tests. At 13 years old, he had 3 to 4 mm ST segment depression in the infero-lateral leads without symptoms. This progressed to 4.2 mm inferior ST segment depression at 15 years old with normal stress echocardiogram. Sestamibi myocardial perfusion scan and cardiac magnetic resonance imaging was inconclusive. Therefore, a coronary angiogram was obtained which showed complete occlusion of the LMCA with ample collateralization from the right coronary artery system. This was later confirmed on a computed tomogram (CT) angiogram, obtained in preparation of coronary artery bypass grafting. The case illustrates the difficulty of detecting coronary artery stenosis and occlusion in young patients with rich collateralization. Coronary CT angiogram and conventional angiography were the best imaging modalities to detect coronary anomalies in this adolescent with surgically corrected TGA. Screening CT angiography may be warranted for TGA patients, particularly for those with known coronary anomalies. PMID:27574609

    Increased carotid stiffness and impaired brachial artery flow-mediated dilatation (FMD) associate with cardiovascular events. We have previously reported three FMD patterns based on the time of maximal dilatation. The aim of the present study was to verify whether different FMD patterns associate with carotid artery stiffness. In all, 133 subjects were enrolled. All participants underwent complete clinical examination, blood sampling and ultrasound study. FMD was used as a measure of endothelial function. Based on the maximal brachial artery FMD, subjects were divided into Early dilators (peak FMD at 50 s), Late dilators (peak FMD over 50 s) and No dilators. Echo-Doppler evaluation of carotid arteries was performed in order to calculate elastic indexes (strain, β-stiffness index and distensibility). In all, 64 subjects were classified as Early FMD, 36 as Late FMD and 33 as No dilators. Age, gender and cardiovascular risk factors were comparable among three groups. Early FMD had higher values of strain compared with both Late and no Dilators (PFMD and No Dilators were detected. Our results demonstrate that common carotid artery elasticity indexes significantly differ among Early, Late and No dilators. Subjects with delayed or absent brachial artery dilatation have stiffer common carotid arteries compared with subjects with early dilatation. In conclusion, our research suggests that the assessment of the kinetics of FMD in a clinical setting might represent a useful screening tool to improve the cardiovascular risk stratification.

    We describe the MRA and MR angiography (MRA) features of persistent trigeminal artery (PTA) found incidentally in eight patients, with special attention to its origin, site and course. The different patterns of posterior communicating arteries were also noted. The PTA were shown on sagittal, coronal and axial MRI and on MRA. In four cases, the PTA arose from the lateral aspect of the intracavernous internal carotid artery, ran caudally, passing round the bottom of the dorsum sellae to join the basilar artery. In the other four cases, it arose from the medial aspect, ran caudally through the sella turcica and pierced the dorsum sellae to join the basilar artery. The posterior communicating arteries were present unilaterally in five cases and bilaterally in one, and absent bilaterally in two. Identification of a PTA with a trans-sellar course is crucial if a trans-sphenoidal surgery is planned. (orig.). With 3 figs.

    Full Text Available Objective. This paper illustrates the evolution of our knowledge of the arterial pulse from ancient times to the present. Several techniques for arterial pulse evaluation throughout history are discussed. Methods. Using databases including Worldcat, Pubmed, and Emory University Libraries' Catalogue, the significance of the arterial pulse is discussed in three historical eras of medicine: ancient, medieval, and modern. Summary. Techniques used over time to analyze arterial pulse and its characteristics have advanced from simple evaluation by touch to complex methodologies such as ultrasonography and plethysmography. Today's understanding of the various characteristics of the arterial pulse relies on our ancestors' observations and experiments. The pursuit of science continues to lead to major advancements in our knowledge of the arterial pulse and its application in diagnosis of atherosclerotic disease.

    2016-06-27

    Hemobilia is an uncommon and potential life-threatening condition mainly due to hepato-biliary tree traumatic or iatrogenic injuries. Spontaneously ruptured aneurysm of the hepatic artery is seldom described. We report the case of an 89-year-old woman presenting with abdominal pain, jaundice and gastrointestinal bleeding, whose ultrasound and computed tomography revealed a non-traumatic, spontaneous aneurysm of the right hepatic artery. The oeso-gastro-duodenoscopy and colonoscopy did not reveal any bleeding at the ampulla of Vater, nor anywhere else. Selective angiography confirmed the diagnosis of hepatic artery aneurysm and revealed a full hepatic artery originating from the superior mesenteric artery. The patient was successfully treated by selective embolization of microcoils. We discuss the etiologies of hemobilia and its treatment with selective embolization, which remains favored over surgical treatment. Although aneurysm of the hepatic artery is rare, especially without trauma, a high index of suspicion is needed in order to ensure appropriate treatment. PMID:27358680

    Ulnar artery aneurysms are an exceedingly rare entity in the pediatric population and have no consistent etiologic mechanism. We present the case of a 15-year-old male with a multilocular ulnar artery aneurysm in the setting of no antecedent history of trauma, no identifiable connective tissue disorders, and no other apparent etiological factors. Furthermore, the patient's arterial palmar arch system was absent. The aneurysm was resected, and arterial reconstruction was successfully performed via open surgical approach with cephalic vein interposition graft. We believe this treatment modality should be considered as the primary approach in all of these pediatric cases in consideration of the possible pitfalls of less comprehensive measures.

    International Nuclear Information System (INIS)

    The case of a 13-month-old boy with fibromuscular dysplasia (FMD) presenting with a large saccular aneurysm of the left renal artery and renovascular hypertension is reported. Renal and intrarenal arteries showed numerous small aneurysms alternating with stenoses. All arterial lesions were localized to the left kidney. After left nephrectomy, the patient's blood pressure normalized. Histopathologic examination of the arteries disclosed changes typical of medial fibroplasias, the most frequently described form of FMD in children. This diagnosis is rewarding as it represents a surgically curable cause of severe hypertension. (orig.)

    We present a patient with an acutely ruptured, wide-necked aneurysm of the left posterior cerebral artery (PCA) treated with Guglielmi detachable coils using the remodeling technique. Since the left vertebral artery was compressed due to a tumor in the cerebellopontine angle and the right vertebral artery was hypoplastic, we used a carotid artery approach via a persistent primitive trigeminal artery (PPTA) to selectively catheterize the aneurysm. The aneurysm was occluded completely. To our knowledge this is the first case of a wide-necked PCA aneurysm treated via a PPTA and using the remodeling technique. In patients with hypoplastic vertebral arteries and a PPTA, this approach may represent an alternative for selective embolization of posterior circulation aneurysms not amenable to the conventional approach.

    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 .

    Full Text Available Abstract A coronary arterial fistula is a connection between one or more of the coronary arteries and a cardiac chamber or great vessel. This is a rare defect and usually occurs in isolation. Its exact incidence is unknown. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. They do not usually cause symptoms or complications in the first two decades, especially when small. After this age, the frequency of both symptoms and complications increases. Complications include 'steal' from the adjacent myocardium, thrombosis and embolism, cardiac failure, atrial fibrillation, rupture, endocarditis/endarteritis and arrhythmias. Thrombosis within the fistula is rare but may cause acute myocardial infarction, paroxysmal atrial fibrillation and ventricular arrhythmias. Spontaneous rupture of the aneurysmal fistula causing haemopericardium has also been reported. The main differential diagnosis is patent arterial duct, although other congenital arteriovenous shunts need to be excluded. Whilst two-dimensional echocardiography helps to differentiate between the different shunts, coronary angiography is the main diagnostic tool for the delineation of the anatomy. Surgery was the traditional method of treatment but nowadays catheter closure is recommended using a variety of closure devices, such as coils, or other devices. With the catheter technique, the results are excellent with infrequent complications. Disease name and synonyms Coronary arterial fistulas Coronary arterial fistulas or malformations

    The present report describes an unusual case of an aneurysm of a right hepatic artery (RHA) branching from the superior mesenteric artery; the accessory RHA was looped to the left hepatic artery arising from the celiac axis (CA) and was associated with congenital atresia of the CA. The accessory RHA aneurysm was treated with the placement of a bare stent and detachable coils through the mesh of the stent. Complete and prompt exclusion of the aneurysm was achieved with blood flow preservation in the parent artery at midterm follow-up. PMID:18656020

  7. Analysis of linguistic terms of variables representing the wave of arterial diameter variation in radial arteries using fuzzy entropies

    International Nuclear Information System (INIS)

    In this work we use 53 Arterial Diameter Variation (ADV) waves extracted from radial artery of normotense males, along with the values of variables that represent the ADV wave, obtained by means of multivariate analysis. Then, we specify the linguistic variables and the linguistic terms. The variables are fuzzified using triangular and trapezoidal fuzzy numbers. We analyze the fuzziness of the linguistic terms by applying discrete and continuous fuzzy entropies. Finally, we infer which variable presents the greatest disorder associated to the loss of arterial elasticity in radial artery

    Full Text Available Abstract Background This paper presents calculations of the temperature distribution in an atherosclerotic plaque experiencing an inflammatory process; it analyzes the presence of hot spots in the plaque region and their relationship to blood flow, arterial geometry, and inflammatory cell distribution. Determination of the plaque temperature has become an important topic because plaques showing a temperature inhomogeneity have a higher likelihood of rupture. As a result, monitoring plaque temperature and knowing the factors affecting it can help in the prevention of sudden rupture. Methods The transient temperature profile in inflamed atherosclerotic plaques is calculated by solving an energy equation and the Navier-Stokes equations in 2D idealized arterial models of a bending artery and an arterial bifurcation. For obtaining the numerical solution, the commercial package COMSOL 3.2 was used. The calculations correspond to a parametric study where arterial type and size, as well as plaque geometry and composition, are varied. These calculations are used to analyze the contribution of different factors affecting arterial wall temperature measurements. The main factors considered are the metabolic heat production of inflammatory cells, atherosclerotic plaque length lp, inflammatory cell layer length lmp, and inflammatory cell layer thickness dmp. Results The calculations indicate that the best location to perform the temperature measurement is at the back region of the plaque (0.5 ≤ l/lp ≤ 0.7. The location of the maximum temperature, or hot spot, at the plaque surface can move during the cardiac cycle depending on the arterial geometry and is a direct result of the blood flow pattern. For the bending artery, the hot spot moves 0.6 millimeters along the longitudinal direction; for the arterial bifurcation, the hot spot is concentrated at a single location due to the flow recirculation observed at both ends of the plaque.

  18. Neurofibromatosis Type 1: Transcatheter Arterial Embolization for Ruptured Occipital Arterial Aneurysms

    International Nuclear Information System (INIS)

    Two cases of ruptured aneurysms in the posterior cervical regions associated with type-1 neurofibromatosis treated by transcatheter embolization are reported. Patients presented with acute onset of swelling and pain in the affected areas. Emergently performed contrast-enhanced CT demonstrated aneurysms and large hematomas widespread in the posterior cervical regions. Angiography revealed aneurysms and extravasations of the occipital artery. Patients were successfully treated by percutaneous transcatheter arterial microcoil embolization. Transcatheter arterial embolization therapy was found to be an effective method for treating aneurysmal rupture in the posterior cervical regions occurring in association with type-1 neurofibromatosis. A literature review revealed that rupture of an occipital arterial aneurysm, in the setting of neurofibromatosis type 1, has not been reported previously.

    Dolichoectasia is a medical term used to describe elongated and dilated vessels that follow a tortuous and windy course with frequent loops and curves. We are presenting the natural history in images of a normal basilar artery becoming dolichoectatic, followed by the formation of an aneurysm, over a period of many years, in 60-year-old Caucasian man with a long history of secondary progressive multiple sclerosis and uncontrolled arterial hypertension, who was diagnosed with dolichoectasia of basilar artery in 2008. Although relatively stable at this point, eventually his mobility deteriorated and signs from the cranial nerves, such as trigeminal neuralgia and bilateral palsy of the VI and the VII nerves were added in the clinical picture. In 2014, both computed tomography and magnetic resonance imaging of the brain revealed the formation of an unruptured aneurysm of the basilar artery. PMID:25765208

    Spontaneous coronary artery dissection is a rare and often fatal condition of pregnancy. The long-term morbidity is unknown, but a small cohort of patients develop severe ventricular dysfunction as a consequence. We describe a 37-week gestation parturient who presented with cardiogenic shock secondary to spontaneous left main coronary artery dissection. Despite rapid diagnosis, stabilisation with an intra-aortic balloon pump and prompt transfer to a tertiary centre for emergency caesarean delivery and coronary artery bypass grafting, the patient developed a severe postoperative dilated ischaemic cardiomyopathy. There is little information about the long-term outcomes and the specific anaesthesia management of combined emergency caesarean delivery and cardiac surgery in pregnancy for spontaneous coronary artery dissection. Therefore, we outline our multidisciplinary management of this critically ill pregnant woman. PMID:23530793

  1. Сharacteristics of flexible elastic properties of the carotid arteries in women with arterial hypertension

    Full Text Available The article presents the results of study of the features of the carotid wall structure using ultrasound scanning with differential measurement of intima and media thickness, as well as characteristics of arterial elasticity in women with hypertension without comorbidities. It is shown that in women with hypertension vascular remodeling occurs mainly in the form of thickening of the intima-media due to increase in the media layer and is associated with remodeling of the left heart. Carotid remodeling in women with hypertension is associated with worsening of vascular elasticity - increased vascular stiffness and decreased distension, wherein correlation analysis has shown that mentioned parameters are mostly associated with thickening of the medial layer of the artery wall and increase of internal diameter of the artery, as well as with increase in left ventricular mass. Ultrasound method of estimating elastic characteristics of arterial vessels is informative, relatively inexpensive and safe.

    An ipsilateral stenosis of the internal carotid artery is found in 10 - 15 % of all ischemic strokes and indicates an increased risk of a second stroke. Carotid artery stenting (CAS) is a therapy that is established for many years. CAS reveals complication rates and long-term efficacy comparable to carotid endarterectomy (TEA). Especially younger patients seem to benefit from CAS. Abilities and experiences of the therapist and the choice of the techniques used are critical for patient safety. The efficacy of CAS for treatment of asymptomatic carotid stenosis is probable but still unproven in prospective-randomized trial. (orig.)

    Persistent carotid-vertebrobasilar anastomoses (PCVBA) include the primitive trigeminal artery (PTA), the primitive otic artery (POA), the primitive hypoglossal artery and proatlantal arteries (ProAs). The PTA is the most commonly seen of these accounting for approximately 80-85% of PCVBAs. The PTA which connects the internal carotid artery (ICA) to the basilar artery (BA) may occasionally connect to the superior or posterior inferior cerebellar arteries without interposition to the BA. It is then referred to as a persistent trigeminal artery variant (PTAV), an anomalous carotid-cerebellar anastomosis. Bilateral occurrence of PTA is extremely rare. During vertebral artery (VA) development the anterior radicular artery of segment C1 from the proatlantal artery of Padget evolves into the intradural component of the VA (V4 segment) plus a short extradural segment (distal V3 segment). Agenesis of a single anterior radicular artery of ProA results in the absence of one distal VA associated with an unremarkable contralateral VA and the BA. Absence or hypoplasia of the terminal portion of one VA is a commonly observed anatomic variant. However, absence of the terminal portions of both VAs is exceptional. A rare case of bilateral PTAs is presented with unilateral PTA and a contralateral PTAV causing trigeminal neuralgia. Furthermore, the bilateral PTAs were associated with the absence of the proximal portion of the BA in addition to the bilateral lack of a distal VA. This finding comes as a logical consequence of the developmental anatomy of the vertebrobasilar junction and is consistent with the assumed congenital nature of the anatomic variant. PMID:22113402

    Full Text Available Enrico Agabiti-Rosei, Enzo Porteri, Damiano RizzoniClinica Medica, Department of Medical and Surgical Sciences, University of Brescia, ItalyAbstract: Arterial stiffness plays a key role in the pathophysiology of the cardiovascular system. Some indices of arterial stiffness (pulse wave velocity, augmentation index, characteristics of central blood pressure waveform may be presently calculated and evaluated in the clinical setting. Age and blood pressure are the two major clinical determinants of increased arterial stiffness, while molecular determinants of arterial stiffness are related to fibrotic components of the extracellular matrix, mainly elastin, collagen and fibronectin. Increased arterial stiffness has been consistently observed in conditions such as hypertension, dyslipidemia and diabetes. Arterial stiffness evaluated by means of carotid-femoral pulse wave velocity yielded prognostic significance beyond and above traditional risk factors. A more favorable effect of calcium channel blockers, diuretics and ACE inhibitors compared with β-blockers on indices of arterial stiffness was observed in several studies. It is conceivable that newer β-blockers with additional vasodilating properties, such as nebivolol, which has favorable effects on carbohydrate and lipid metabolism, as well as on endothelial function and on oxidative stress, may have favorable effects on arterial stiffness, compared with atenolol. In fact, in recent studies, nebivolol was demonstrated to improve artery stiffness to a greater extent than older β-blockers. Because endothelial dysfunction and increased arterial stiffness play an important role in the early atherosclerotic processes and are associated with poor outcomes and increased mortality, independently of blood pressure, the ability of nebivolol to enhance release of endothelium-derived nitric oxide, and consequently improve endothelial function and arterial stiffness, may have significant clinical

    Full Text Available Aims and Objectives: To study the incidence, demographic profile, and outcome of patients with severe closed head injuries who develop acute arterial infarcts. Materials and Methods: Patients with severe head injury (Glasgow coma score (GCS ≤8 presenting within 8 h of injury in the Department of Neurosurgery over a period of 5 months were enrolled in the study. Patients with penetrating head injury, infarct due to herniation and iatrogenic arterial injuries were excluded from the study. Only arterial infarcts developing within 8 h of injury were included in the study. A computed tomography (CT head was done on all patients within 8 h of injury and repeated if necessary. Arterial infarct was defined as well-demarcated wedge-shaped hypodensity corresponding to an arterial territory on plain CT of the head. Outcome was assessed using Glasgow outcome score (GOS at 1 month post-injury or at death (whichever came earlier. Results: Forty-four patients of severe head injury were included in the study during the above period. Of these, four patients (9.1% had arterial infarcts on the initial CT scan. The male:female ratio was 1:3. The mean age was 54 years (range 3-85 years. Two patients had infarcts in the middle cerebral artery distribution and two in the superior cerebellar artery distribution. Poor outcome (GOS 1-3 was seen in 100% of the patients with arterial infarct compared to 52.5% (n=21 in patients with severe head injury without arterial infarct. Conclusions: A significant percentage of patients with severe head injury have arterial infarcts on admission, which may imply arterial injury. Our study shows that these patients have a poorer prognosis vis-a-vis patient without these findings.

  9. Pulmonary Artery Access Embolization in Patients with Massive Hemoptysis in Whom Bronchial and/or Nonbronchial Systemic Artery Embolization Is Contraindicated

    International Nuclear Information System (INIS)

    The objective of this paper is to present an alternative therapeutic approach for the treatment of patients with massive hemoptysis in whom bronchial and/or nonbronchial systemic arterial embolization is not possible. We describe a percutaneous procedure for pulmonary segmental artery embolization. Between May 2000 and July 2006, 27 adult patients with hemoptysis underwent percutaneous treatment at our department; 20 of 27 patients were embolized via bronchial and or nonbronchial systemic arteries and 7 patients were embolized via pulmonary artery. Femoral arterial access for systemic artery catheterization and femoral vein access for pulmonary arterial catheterization were used. Gelfoam particles and coils were used for embolization. In this study, we report on three cases of massive hemoptysis from a systemic arterial source in whom bronchial and/or nonbronchial arteries embolization was not possible. Percutaneous embolization via the pulmonary artery access was successful in all three patients. In conclusion, embolization via pulmonary artery is presented as an alternative approach for the management of hemoptysis in patients in whom bronchial arterial embolization is not possible

    Boutouyrie, Pierre

    2011-09-10

    Arterial stiffness has emerged as an important marker of cardiovascular risk in various populations and reflects the cumulative effect of cardiovascular risk factors on large arteries, which in turn is modulated by genetic background. Arterial stiffness is determined by the composition of the arterial wall and the arrangement of these components, and can be studied in humans non-invasively. Age and distending pressure are two major factors influencing large artery stiffness. Change in arterial stiffness with drugs is an important endpoint in clinical trials, although evidence for arterial stiffness as a therapeutic target still needs to be confirmed. Drugs that independently affect arterial stiffness include antihypertensive drugs, mostly blockers of the renin-angiotensin-aldosterone system, hormone replacement therapy and some antidiabetic drugs such as glitazones. While the quest continues for \\'de-stiffening drugs\\

    Full Text Available Knowledge of variations of blood vessels of the abdomen is important during operative, diagnostic and endovascular pro- cedures. During routine dissection of the abdominal cavity, we came across multiple vascular anomalies involving renal, suprarenal and testicular arteries. The left kidney was supplied by two renal arteries originating together from the abdomi- nal aorta, and the right kidney was supplied by two accessory renal arteries, one of which was arising from the right renal artery and the other one from the aorta (about 2 inches below the origin of the renal artery. Accessory renal veins were present on both sides. The right testicular artery was arising from the lower accessory renal artery. The left testicular artery was looping around the inferior tributary of the left renal vein, whereby forming a sharp kink. The left middle suprarenal artery was diving into three small branches; the upper two branches were supplying the left suprarenal gland, whereas the lower branch was supplying the left kidney. Furthermore, detailed literature and the clinical and surgical importance of the case are discussed. [Arch Clin Exp Surg 2015; 4(3.000: 168-171

  13. Helical CT evaluation of internal carotid artery stenoses

    International Nuclear Information System (INIS)

    To determine the utility of helical CT angiography in the evaluation of carotid artery stenoses, helical CT images (reconstructed three-dimensional images, reconstructed multiplanar images, and two-dimensional axial images) obtained from 60 patients were compared with images obtained using conventional angiography. Based on conventional angiographic criteria, 22 arteries had no stenosis, 26 had mild stenosis. 69 had severe stenosis, and 3 were occluded. All carotid bifurcations were clearly identified on helical CT scanning and there were no complications. There were no motion artifacts due to the short examination time. In normal arteries, reconstructed three-dimensional images provided accurate anatomic depiction of the carotid bifurcation. Calcification was present at the stenotic lesion in 52 arteries. In 43 arteries in which the stenotic lesion was free of calcification, the degree of carotid stenosis determined using reconstructed three-dimensional images correlated with that determined using conventional angiography. In 19 of 52 arteries with calcification at the stenotic lesion, the calcification was focal and did not obscure the vessel lumen significantly when viewed from multiple angles. In the other 33 arteries, the calcification was dense and/or circumferential, making it difficult to evaluate the axial images allowed evaluation of the vessel lumen in the area of calcification, and the degree of stenosis was similar to that determined by conventional angiography. In 3 arteries, occlusion of the internal carotid artery was seen in reconstructed three-dimensional images and was confirmed by conventional angiography. (K.H.)

    Full Text Available Background: Pulse wave velocity (PWV is widely used for estimating the stiffness of an artery. Various invasive and non-invasive methods have been developed to determine PWV over the years. In the present research, the non-invasive estimation of the PWV of large arteries was used as an index for arterial stiffness. Methods: A dynamic model based on the Navier-Stokes equations coupled to elasticity equations was introduced for the PWV in arteries with elastic walls. This system of equations was completed by clinical information obtained from the Doppler ultrasound images of the carotid artery of 40 healthy male volunteers. For this purpose, the Doppler ultrasound images were recorded and saved in a computer; and subsequently center-line blood velocity, arterial wall thickness, and arterial radius were measured by offline processing. Results: The results from the analytic solution of the completed equations showed that the mean value of PWV for the group of healthy volunteers was 2.35 m/s when the mean arterial radius was used as the neutral radius and 5.00 m/s when the end-diastole radius was used as the neutral radius. It is noteworthy that the latter value closely complies with that reported by other researchers. Conclusion: By applying this method, a non-invasive clinical and local evaluation of the common carotid artery stiffness via a Doppler ultrasound measurement will be possible.

    A 32-year-old woman hospitalized for subarachnoid hemorrhage showed rare arterial variation on the right side with anomalous origins of the vertebral artery, aberrant subclavian artery and persistent trigeminal artery. Angiography showed the right vertebral artery to originate from the right common carotid artery, the right subclavian artery to arise separately from the descending aorta, and persistent trigeminal artery on the right side. The possible embryonic mechanism of this previously unreported variant combination is discussed. PMID:22005696

    blood pressure. This review considers the alterations in systemic hemodynamics in patients with cirrhosis in relation to essential hypertension and arterial hypertension of the renal origin. Subjects with arterial hypertension (essential, secondary) may become normotensive during the development of...... cirrhosis, and arterial hypertension is rarely manifested in patients with cirrhosis, even in cases with renovascular disease and high circulating renin activity. There is much dispute as to the understanding of homoeostatic regulation in cirrhotic patients with manifest arterial hypertension. This most...

    Full Text Available Gold standard treatment of hepatocellular carci-noma is surgical resection but more than 80% of patients with HCC are unresectable at the time of diagnosis, and due to poor local circumstances or the patient's general condition, the prognosis is poor. "nBecause HCC tumors are fed exclusively by the he-patic artery, successful TACE leads to tumor necrosis. The liver parenchyma is rarely damaged because it is fed by the portal vein. Injection of an emulsion of iodized oil and cytostatic agents into the hepatic artery leads to selective deposition of the emulsion in the tumor. Compared with intravenous administration of cytostatic material, TACE reduces the maximum plasma concentration and increases the average concentration of cytostatic agents in the tumor, especially when the cytostatic material is combined with gelatin powder particles. "nFor example, concentration of an emulsion of cisplatin in iodized oil 4-9 weeks after intraarterial administration is 42 times greater in the tumor than in the parenchyma."nTwo cases of HCC are presented which were treated successfully with TACE 20 months ago."nIn the first patient after one session of TACE, tumor markers fell down into normal range and MDCT showed complete necrosis and cystic changes in the mass without residual or recurrent tumor until this time. "nIn the next case tumor markers showed no significant decrease after the first session of TACE and MDCT showed residual tumor which was fed by an accessory arterial branch from SMA. This branch was treated in another session. Two months later, tumor markers fell down and MDCT showed no tumor activity. "nThese patients have been symptom free after the mentioned interventions.

    Reimplantation after subtotal section of the right lower limb under the Scarpa triangle was been attempted and was successful. Section and contusion of the femoral artery and vein required 2 end-to-end saphenous bypass grafts. The use of the lower limb is correct, after to a follow up of 4 years. The risks, inherent to all proximal section, with important muscular masses, in a small child, are described. Functional prognosis depends on three aspects: bone, vessels, and nerves. A tibial pseudarthrosis had to be operated secondarily with significant lengthening. A partial stenosis of the graft was demonstrated arteriographically. Pes equinus, a result of paralysis, has been fitted with an orthesis. This observation is almost an experimental one: what can be the future of a reimplanted lower limb in the child. PMID:2930140

    The structure of the large coronary arteries is both heritable and reasonably consistent between individuals, but the extent to which this results from evolutionary pressure towards an energy-efficient, globally-optimal, structure is unknown. We present an algorithm for the determination of an energetically globally optimal arterial tree in arbitrary tissue geometries. We demonstrate through application of the algorithm that it is possible to generate in-silico vasculatures that closely match porcine anatomical data on all length scales. We therefore conclude that evolutionary pressure has resulted in a near globally optimal structure of the larger coronary arteries. We also examine the effect of changing length scales, predicting that the structures of the coronary arteries can change from a meandering form for small animals to very straight vessels for large animals. The method presented here is not limited to hearts, and represents a major advance in modeling the arterial vasculature, that could have impor...
