    Introduction: Mesenteric fibromatosis is a rare type of tumour,histological benign appearance but local aggressive behavior, prone to residivar, but lacks the ability to metastasize. The called desmoid tumour is a type of aggressive fibromatosis, a rare presentation representing less than 0.03% of all tumours with an annual incidence of 2-4 cases / 100,000. Mesenteric fibromatosis can be divided into two broad categories: one superficial and deep. The processes are superficially localized, located on the palms, soles, penis and knuckles. The deep shape is more aggressive, turns easily and can cause death by local invasion. It is subdivided in abdominal, extra abdominal and intraabdominal in which we find the pelvic fibromatosis, and mesenteric associated with inherited familial polyposis. Clinically, these tumours usually appear as a mass whose symptoms depend on the location; in the abdominal region, it will normally cause intestinal obstruction and hydronephrosis, bleeding or perforation of hollow viscera, or remain asymptomatic for a long time performing diagnosis belatedly when its size is large as in our case. Objectives: To report a case of mesenteric fibromatosis low frequency with a good clinical outcome after a treatment based on a comprehensive literature review. Methodology A case history of a female patient 57 years, no history is taken. Presented with an poor performance status, overall impact, weight loss of 10kg in 6 months. Right upper quadrant pain and bloating prandrial post. He studied with computed tomography, which describes the presence of a large tumour retroperitoneal in intimate contact with the intestinal loops. No lymphadenopathy. A laparotomy was performed explorer in which the presence of the tumour conforms to level stony member mesenteric planes later. Being an unresectable tumour. Pathology describes: fibro myxoid lesion without elements malignancy, compatible with mesenteric fibromatosis. Hormone receptor positive. Currently there

    Full Text Available Mesenteric fibromatosis or intra-abdominal desmoids tumor is a rare clinical entity. It is a locally aggressive tumor but not metastasizing proliferation. We report a case of a 27-year-old woman with no significant medical and a previous cesarean section, admitted for abdominal pain. The CT abdominal evaluation revealed subserosal uterine fibroid. The patient underwent an elective laparotomy and a mass measuring 20/15/15 cm in diameter to the medial wall of the cecum was discovered. Complete removal was accomplished with right hemicolectomy. Histopathological examination reported mesenteric fibromatosis. Postoperatively, patient was well and 6 month follow-up showed good recovery. Moreover the next month she became pregnant and the pregnancy and birth were uneventful.

    Gardner's syndrome (GS), a variant of familial adenomatous polyposis, is an autosomal dominant disease. Originally, Gardner described a syndrome consisting of hereditary intestinal polyposis With osteomas and multiple cutaneous and subcutaneous lesions. The syndrome was later modified by the addition of other features, such as dental abnormalities, abdominal fibromatosis, and a number of malignant tumors. the principal cutaneous lesions that have been described in GS are epidermoid cysts. Other cutaneous lesions include fibromas, lipomas, leiomyomas, neurofibromas, and pigmented skin lesions. Fibromatoses are histologically benign, but locally aggressive fibrous tumors consisting of mature fibroblasts within an extensive collagen matrix. Most cases are sporadic, but there is a clear association with familial adenomatous polyposis and GS, suggesting a link with a mutation of the APC gene on chromosome 5q22. Fibromatosis occurs in 3.5%-29% of patients with GS, and is more likely to be multiple and to involve the mesentery and abdominal wall rather than being an isolated form. Clinically, fibromatosis presents as a painless firm soft tissue mass. Most cases of fibromatosis are believed to be precipitated by surgical trauma, however, a few cases of spontaneous occurrence have been reported. In our patient, no history of abdominal surgery or trauma was present. In addition, an abdominal CT obtained 2 years ago revealed no abnormality. Although the radiological features of fibromatosis on CT or MR have been described in the literature, F 18 FDG PET or PET/CT findings are rarely reported. The F 18 FDG uptake in patients with fibromatosis ranged from low to moderate grade and was generally heterogenous with a few tiny foci of relatively intense uptake or relatively homogenous. The areas of higher FDG metabolism are likely to represent more cellular and mitotically active areas. Mesenteric fibromatosis has similar findings to extra abdominal lesions.

    Extra-abdominal fibromatosis (desmoid tumour) is a rare aggressive neoplasm with a tendency to infiltrate local structures but rarely metastasises or undergoes spontaneous malignant transformation. The treatment of choice is surgery, however, recurrences have been reported even after wide-field resection. This article presents a case of extra-abdominal fibromatosis that had extensively invaded the mandible.

    Fibromatosis is a rare benign tumor that presents predominantly as a unilateral, painless, palpable, and firm to hard mass which may be accompanied by skin dimpling and nipple retraction. It is characterized as an infiltrating fibroblastic and myofibroblastic proliferation that can behave in a locally aggressive fashion if incompletely excised. However, it is not known to metastasize. We report a case of a 39-year-old female with recurrent fibromatosis in the breast. Initially, the mass was detected by a screening mammography. It appeared as an oval mass and recurred twice after surgical excision over a 36-month period with a more suspicious appearance.

    Full Text Available Hypertrichosis is a rare disorder that causes abnormal excessive body hair growth. Hypertrichosis has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. It is often associated with additional anomalies including gingival hyperplasia, deafness, cardiomegaly and bone abnormalities. The association of gingival fibromatosis and a coarse facies could further worsen the esthetics. Thus, a multidisciplinary approach involving a psychologist, a dentist as well as a dermatologist would be mandatory. We present this rare syndrome describing a case of a 9-year-old boy with congenital hypertrichosis and gingival fibromatosis. The growth being normal, the features of this boy were similar to hypertrichosis. Hypertrichosis has informally been called werewolf syndrome because the appearance is similar to the werewolf.

    Full Text Available Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

    Full Text Available We describe a rare case of aggressive fibromatosis of the larynx occurring in a 72-year-old man. The lesion manifested with complaints of dyspnea and stridor. A computerized tomographic scan of the neck revealed irregular polypoidal growth invading right vocal cord, crossing midline. A malignant tumor was suspected. Although several laryngoscopy-driven biopsies were negative for malignancy, total laryngectomy was done since the lesion was not deemed amenable to conservative therapy. Tissue sections featured a moderately cellular lesion composed of spindle cells with bland, elongated nuclei, enmeshed in a variably collagenized ground substance. The spindle cells were immunopositive for vimentin and negative for cytokeratins, PGP-9.5, smooth muscle antigen, CD68, desmin, and S-100 protein and Ki-67 of 4%. No further therapy was administered. Based on the available literature, our data confirm that aggressive laryngeal fibromatosis in adult patients is a locally infiltrating disease. Total laryngectomy with clear margins is needed as to avoid the high risk of local recurrence.

    Full Text Available The concomitant presence of the olfactory groove meningioma with uterine fibrosis is very rare. Our report presents the case of a giant olfactory groove meningioma revealed after a uterine fibroma resection in a 44 years-old female, due to a generalized seizure 10 days after operation. Cranial CT-scan identified the tumor as an olfactory groove meningioma. The tumor was operated with a macroscopically complete resection; the endothermal coagulation of the dura attachment was performed (Simpson II with a good postoperative evolution. Laboratory results showed the presence of receptors for steroid hormones both in meningioma and uterine tumor, and the histopathological examination revealed an atypical meningioma with 17% proliferation markers. Our findings suggest that even though meningiomas are benign tumors and a complete resection usually indicates a good prognosis, the association with uterine fibromatosis and the presence of high percentage of steroid receptors creates a higher risk to relapse, imposing therefore a good monitoring.

    Desmoid type fibromatosis is a benign fibroblastic tumor arising from the fascia or musculoaponeurosis. It may occur in various locations, but most commonly in the shoulder girdle and neck; to our knowledge, there has been no reported case originating from a facet joint of the spine. We report CT and MR imaging findings of a desmoid type fibromatosis, involving the facet joint of the L3-4 spine with bone involvement.

    Full Text Available Purpose. Desmoid-type fibromatosis is a benign fibrous neoplasia originating from connective tissue, fascial planes, and musculoaponeurotic structures of the muscles. Currently, there is no evidence-based treatment approach available for desmoid fibromatosis. In this article, a case of a patient in the pediatric age affected by desmoid fibromatosis localized in the orbit is presented. The aim of the article is to describe this unusual and rare location for the desmoid fibromatosis and outline the principle phases in the decision-making process and the therapeutic alternatives for a patient affected by desmoid fibromatosis. Methods. The protocol of this review included study objectives, search strategy, and selection criteria. The primary end point of this study was to analyze the head and neck desmoid fibromatosis. The secondary end point was to identify the available therapies and assess their specific indications. Results. The mean age of patients was 18.9 years ranging from 0 to 66, and 52% were female. A bimodal age distribution was observed, and two age peaks were identified: 0–14 years (57% and 28–42 years (18%. The most common involved areas were the mandible (25% followed by the neck (21%. In 86% of the cases, the treatment was the surgical resection of the disease, and only in 5% of the cases, the surgical resection was followed by adjuvant radiotherapy. Conclusion. The orbital location is extremely rare, especially in the pediatric population. The management of desmoid fibromatosis is based on the function preservation and the maintenance of a good quality of life, but in case of symptomatic patients or aggressive course of the disease or risk of functional damages, the surgical approach may be considered. Therapeutic alternatives to surgical resection are radiotherapy and systemic therapy.

    Full Text Available Abstract Desmoid fibromatoses are benign, slow growing fibroblastic neoplasms, arising from musculoaponeurotic stromal elements. Desmoids are characterized by local invasion, with a high rate of local recurrence and a tendency to destroy adjacent structures and organs. Desmoid fibromatoses are rare in children, and though they may occur in the head and neck region, are extremely rare in the paranasal sinuses. Here we report a case of extraabdominal desmoid fibromatosis in a seven-year-old boy involving the sphenoid sinus, one of only six published reports of desmoid fibromatosis of the paranasal sinuses. The expansile soft tissue mass eroded the walls of the sphenoid sinus as well as the posterior ethmoid air cells extending cephalad through the base of the skull. We discuss the clinicopathologic features of this lesion, including structural and ultrastructural characteristics, and we review the literature regarding treatment and outcome.

    Fibromatosis or desmoid tumor of the breast is a rare benign entity that has no metastatic potential but has significant risk of local recurrence. Its association with previous surgical or accidental trauma and Gardner's syndrome has been reported. Awareness of this lesion is important as the diagnosis is often confused with breast carcinoma. We report a case of a 44-year-old woman who presented with a palpable mass in her left breast, close to the axilla since a few months ago. She had undergone excisional biopsy for her left breast mass 15 months ago, and the diagnosis was confirmed as intraductal papilloma with atypical ductal hyperplasia. Subsequent ultrasound and core needle biopsy revealed stromal fibrosis. After 9 months, the mass showed an increase in its size and the anteroposterior to width ratio on ultrasonography compared to the previous examination, and final excisional biopsy confirmed the diagnosis of desmoid-type fibromatosis.

    Palmar and plantar fascial fibromatoses are benign hyperproliferative disorders of the deep fascia of the palm and sole. This study seeks to examine the role of radiotherapy in the management of fascial fibromatosis. Six consecutive cases of early-stage fascial fibromatosis treated with radiotherapy at the Adelaide Radiotherapy Centre between July 2008 and May 2011 were analysed. The results of the case series were compared with a systematic review of the literature. All six cases regressed or showed a reduction of symptoms following radiotherapy. Treatment was well tolerated with minor toxicities. Median follow-up for the case series was 38.5 months. The systematic review identified seven studies describing the use of radiotherapy as primary treatment for fascial fibromatosis between 1946 and 2013. The literature indicates that radiotherapy can prevent disease progression and improve symptoms for early-stage disease, with low likelihood of significant toxicities. Early results from our case series are consistent with the literature, showing that radiotherapy can provide an effective management option for patients with early-stage fascial fibromatosis, and justify consideration of radiotherapy as a primary treatment for early-stage disease.

    Musculoaponeurotic fibromatosis is a well-differentiated benign tumoral condition of fibroblastic origin that is classified as a tumor of the soft tissue. These lesions present an intermediate biological behavior between the benign fibroblastic tumors and fibrosarcoma, and have the capacity of presenting local relapse, but never metastasis. One case of post-traumatic musculoaponeurotic fibromatosis of the scalene muscle is presented by the study of the ultrasonography, CT and MRI. The imaging findings are not characteristics, but they are useful to carry out the differential diagnosis and extension study. (Author) 14 refs.

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

    2010-01-01

    Full Text Available Background. Hereditary gingival fibromatosis is a fibrotic enlargement of the gingiva. It may exist as an isolated abnormality or as part of multisystem syndrome. This paper reports a case of 16-year-old male with generalized severe gingival overgrowth, involving the maxillary and mandibular arches and covering almost all teeth. Methods. Periodontal management of gingival enlargement included gingivectomy in both arches except in the lower right molar region where flap surgery was done under general anesthesia. After a 2-month followup period, orthodontic treatment was started with fixed appliances. Monthly periodontal checkups and maintainance (scaling and polishing were scheduled to control the gingival inflammation. Results. Reevaluation of the patient of surgical treatment after two months did not show any recurrence of condition; however, minimal overgrowth was noted 1 month after the beginning of orthodontic treatment which was treated nonsurgically. Conclusions. Although the risk of recurrence is high with this condition, surgical treatment with correction of malocclusion and regular followup can provide excellent outcome as seen in this case.

    Thrombophlebitis occurs secondarily to inflammatory conditions of adjacent organs, and radiologic finding is essential for diagnosis. However, because of the rarity on clinical cases that involve the inferior mesenteric vein, many radiologists are unfamiliar with its location and appearance. We experience a case of septic thrombophlebitis with abscess complication sigmoid diverticulitis. CT scans reveals a low density thrombus and air in the inferior mesenteric vein, combining with perivascular fat infiltration, and focal wall defects with abscess formation. After surgical treatment, the abscess was not visible in the follow-up CT scans. Septic thrombophlebitis of the inferior mesenteric vein, although being a rare disease, should be diagnosed on CT according to the given unique location, the appearance of inflamed vein and the adjacent descending mesocolon.

    We report a case of desmoid fibromatosis of the chest wall. A 70-year-old woman was referred to our hospital with right shoulder blade pain and paresthesia over the right upper breast. Chest X-ray and computed tomography demonstrated a 5 cm right apical mass in the chest. Biopsy of the mass demonstrated features of desmoid fibromatosis. The patient subsequently underwent surgical resection of the mass and received adjuvant radiation therapy for microscopic positive margins. In conclusion, although desmoid tumour of the chest is rare, it is worth considering in the differential diagnoses of chest wall tumours.

    Retrograde superior mesenteric artery stenting (ROMS) represents a significant development in the treatment of acute mesenteric ischemia. Compared to traditional surgical mesenteric bypass, ROMS is a less invasive technique that avoids many complications associated with emergent mesenteric bypass. This case report illustrates that retrograde superior mesenteric artery (SMA) stenting is an option for the treatment of acute mesenteric ischemia for patients in extremis.

    Full Text Available Abstract Introduction Ischemic bowel disease comprises both mesenteric ischemia and colonic ischemia. Mesenteric ischemia can be divided into acute and chronic ischemia. These are two separate entities, each with their specific clinical presentation and diagnostic and therapeutic modalities. However, diagnosis may be difficult due to the vague symptomatology and subtle signs. Case presentation We report the case of a 68-year-old Caucasian woman who presented with abdominal discomfort, anorexia, melena and fever. A physical examination revealed left lower quadrant tenderness and an irregular pulse. Computed tomography of her abdomen as well as computed tomography enterography, enteroscopy, angiography and small bowel enteroclysis demonstrated an ischemic jejunal segment caused by occlusion of a branch of the superior mesenteric artery. The ischemic segment was resected and an end-to-end anastomosis was performed. The diagnosis of segmental small bowel ischemia was confirmed by histopathological study. Conclusion Mesenteric ischemia is a pathology well-known by surgeons, gastroenterologists and radiologists. Acute and chronic mesenteric ischemia are two separate entities with their own specific clinical presentation, radiological signs and therapeutic modalities. We present the case of a patient with symptoms and signs of chronic mesenteric ischemia despite an acute etiology. To the best of our knowledge, this is the first report presenting a case of acute mesenteric ischemia with segmental superior mesenteric artery occlusion.

    2013-10-01

    Two cases of desmoid-type fibromatosis developing after laparoscopic hernia repair are described: one in a young male 3 years after laparoscopic umbilical hernia repair and the other in a young female 1 year after laparoscopic incisional hernia repair. The male patient presented with a slowly enlarging non-tender firm abdominal wall mass; the female patient had similar findings. Excision biopsy in the male and core biopsy in the female were consistent with fibromatosis. The young male patient underwent resection of the fibromatosis, and the female patient has been managed conservatively. These are the first documented cases of fibromatosis developing after laparoscopic hernia surgery. Whilst the safety of hernia meshes has been assessed in animal studies, it may be that more detailed study of intraperitoneal placement of these meshes is required.

    Full Text Available Abstract Background Visceral artery aneurysms (VAA, although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA and celiac trunk, successfully treated with surgery. Methods A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal CT scan showed an aneurysm of the inferior mesenteric artery with retroperitoneal hematoma. In addition, an obstructive disease of the superior mesenteric artery and celiac axis was observed. Results Upon emergency laparotomy a ruptured inferior mesenteric artery aneurysm was detected. The aneurysm was excised and the artery reconstructed by end-to-end anastomosis. Conclusions This report discusses the etiology, presentation, diagnosis and case management of inferior mesenteric artery aneurysms.

    Full Text Available We report a unique case of a 57-year-old male having a suprarenal thoraco-abdominal aortic aneurysm which is extending till the origin of superior mesenteric artery (SMA. The origins of celiac artery and SMA were totally occluded and filled retrogradely through dense collateral vessels arising from the inferior mesenteric artery. Surprisingly, the patient was not having any symptoms related to mesenteric ischemia. We decided to use a conventional aortic aneurysm stent graft to repair it without revascularizing the occluded mesenteric arteries. After 1 month, CT aortogram was repeated which revealed a well-apposed stent graft with no endoleaks. He did not have any clinical signs and symptoms attributable to mesenteric ischemia.

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

    Venous thrombosis is a serious complication of combined contraceptive usage. However, mesenteric venous thrombosis and intestinal necrosis are infrequently seen in women using oral contraceptives, and in such cases diagnosis is often delayed. We report the case of a 38-year-old obese female patient who presented with acute abdominal pain. A bowel infection was first diagnosed and treated with antibiotics. Contrast-enhanced tomography of the abdomen revealed diffuse ischemia of the small intestine with superior mesenteric thrombosis. Laparotomy with segmental resection of both small and large bowel was performed. No predisposing factor of mesenteric venous thrombosis was demonstrated except association of the combined contraceptive with obesity. This report highlights the need for clinicians to suspect venous mesenteric thrombosis in women of reproductive age with acute abdominal pain and poor physical findings. Detailed personal history including prescriptions should help to quickly and accurately determine the problem.

    A metastatic malignant melanoma is a malignant tumor which can involve virtually every organ system. It has variable radiographic findings which mostly indicate solid masses in the mesentery. We report here on a case of a metastatic malignant melanoma, which is made up of multiple mesenteric cystic tumors that need to differentiate from the mesenteric cystic tumor. These include the cystic spindle cell tumor, cystic teratoma, cystic mesothelioma as well as the mesenteric cystic and the solid tumor, which in turn comprises the gastrointestinal stromal tumor, lymphoma and metastatic lesion. The metastatic malignant melanoma can offer a differential diagnosis when the image findings indicate multiple mesenteric cystic masses, multiple organic metastases, and subcutaneous nodules.

    Directory of Open Access Journals (Sweden)

    Almeida John A

    2008-08-01

    Full Text Available Abstract Introduction Chronic mesenteric ischaemia is an important cause of abdominal pain, especially in older patients with risk factors for vascular disease. Until recently, surgical revascularization procedures such as endarterectomy and aorto-coeliac or aorto-mesenteric bypass grafting were the only available treatment options for patients with chronic mesenteric ischaemia. Percutaneous angioplasty and stenting have recently been shown to be effective and safe alternatives to surgical revascularization in high-risk patients with chronic mesenteric ischaemia. Case Presentation We report an 84-year-old woman with symptoms of chronic mesenteric ischaemia, including post-prandial abdominal pain and weight loss. Investigations demonstrated calcific stenoses at the origins of the celiac, superior mesenteric and inferior mesenteric arteries, along with nonocclusive calcification in the mid-splenic artery. Coeliac artery angioplasty and stenting was performed, resulting in excellent arterial dilatation at the stenotic point and distal filling of the coeliac and superior mesenteric arteries and their branches. Within hours of successful stenting of the coeliac artery, the patient developed severe left upper quadrant pain. Progress imaging demonstrated splenic infarction, likely as a result of calcific emboli dislodged from the calcified plaque at the origin of the celiac artery at the time of angioplasty and stenting. The left upper quadrant pain resolved after 8 days and the patient remains asymptomatic 2 years post-procedure. Conclusion This is the first reported case of splenic infarction complicating otherwise successful coeliac artery stenting, presumably as a consequence of distal embolization of disrupted calcific plaque. This complication, occurring on a background of non-occlusive splenic arterial calcification, represents a novel cause of abdominal pain post-procedure.

    Desmoid-type fibromatosis is a rare, locally infiltrative, mesenchymal neoplasm that is associated with high rates of local recurrence but lacks the potential to metastasise. The disease affects younger individuals, with a peak age of 30 years, and is the most common cause of an anterior abdominal wall mass in young women of childbearing age. It may, however, involve nearly every body part, including the extremities, head and neck, trunk, and abdominal cavity; as such, desmoid-type fibromatosis may present to a range of general and subspecialty radiologists. These rare tumours have a widely variable clinical presentation and unpredictable natural history, hence input from a soft-tissue tumour centre is recommended, although much of the imaging may be performed at the patient's local hospital. The consensus for treatment has changed over the past decade, with most centres moving away from primary radical surgery towards a front-line ‘watch-and-wait’ policy. Therefore, imaging has an increasingly important role to play in both the diagnosis and follow-up of these patients. This review will discuss the typical imaging characteristics of these lesions and suggest diagnostic and follow-up magnetic resonance imaging protocols, with details of suitable sequences and scanning intervals

    Mesenteric cyst is a rare clinical entity especially in pregnancy; therefore, few cases have been reported in the literature. The standard method of their treatment is surgical excision either with laparotomy or laparoscopy. In addition, mesenteric vein thrombosis is a rare and life-threatening condition in pregnancy and needs immediate treatment because it can lead to intestinal necrotic ischemia. This is the first report of the coexistence of mesenteric cysts and mesenteric vein thrombosis during gestation. A 27-year-old Greek woman, gravida 2 para 1, presented at 10 weeks' gestation to the Emergency Unit of our hospital complaining of diffuse abdominal pain which deteriorated the last 3 days, which was localized in her right iliac fossa, along with vomiting. She had undergone open laparotomy and right salpingo-oophorectomy at the age of 23 due to an ovarian cyst. Besides this, her personal and family medical history was unremarkable. She had never received oral contraceptives or any hormone therapy. On arrival, a clinical examination revealed tenderness on palpation of her right iliac fossa, without rebound tenderness or muscle guarding. Within 10 hours of hospitalization, her symptoms deteriorated further with rebound tenderness during the examination, tachycardia, and a drop of 12 units in her hematocrit value. An emergency laparotomy was performed. Two mesenteric cysts and a 60 cm necrotic part of her intestine were revealed intraoperatively. In the postoperative period, she complained of acute abdominal pain, tachycardia, and dyspnea. Computed tomography imaging revealed mesenteric vein thrombosis and pulmonary thromboembolism. She was treated with low molecular weight heparin and she was discharged on the 11th postoperative day. To the best of our knowledge, this is the first report in the literature of a simultaneous mesenteric cyst and mesenteric vein thrombosis in pregnancy. It is known that pregnancy is a state of hypercoagulation and clinicians

    Mesenteric venous thrombosis is a clinically very rare disease, and may cause bowel infarction and gangrene. Difficulty in the diagnosis the disease due to its non-specific symptoms and low prevalence can cause a clinically fatal situation. Mesenteric venous thrombosis may be caused by both congenital and acquired factors, and protein C deficiency, which is a very rare genetic disorder, is one of many causes of mesenteric thrombosis. The authors experienced a case of mesenteric venous thrombosis caused by protein C deficiency in a patient with duodenal ulcer bleeding, so here we report a case together with literature review.

    Four case reports are summarised concerning the management of aggressive fibromatosis in children and adolescents up to the age of 15. It was concluded that radiotherapy should be reserved for recurrences or inoperable cases. A dose of 5000-6000 cGy in 25-30 fractions depending on age of patient, site, and size of tumour is necessary, since most surgical recurrences appear in 12 months, all cases with positive surgical margins should receive doses in the range 4000-4500 cGy for microscopic disease. Radiotherapy-chemotherapy combinations can also be used. (UK)

    Full Text Available Disseminated tuberculosis in HIV infection involves multiple organs. Pulmonary and lymph node involvement are the commonest form of tuberculosis in HIV infection [1, 2]. Other forms of tuberculosis in the absence of lung and lymph node involvement are rare. Various forms of abdominal [3, 4] and neurological [5, 6] tubercular involvement in HIV infection have been reported. But tuberculosis presenting simultaneously with mesenteric and brain abscess has not been reported yet. We report a case of disseminated tuberculosis presenting as mesenteric and cerebral abscess in a HIV case without involving lung and lymph nodes. Bone marrow smears and fine needle aspiration cytology (FNAC from mesenteric lesion were positive for acid fast bacilli (AFB and the diagnosis of tuberculosis was confirmed by positive polymerase chain reaction (PCR. He responded well to treatment with anti tubercular drugs.

    In 1998-99, six patients with plantar fibromatosis were submitted to US (ultrasound) with plantar fibromatosis were submitted to US with 13 MHz linear array and 20 MHz mechanical annular array probes. All patients were examined in prone recumbency with the probe positioned on the sole of the foot. Only some of them were subsequently submitted to surgery. Plantar fibromatosis exhibited an almost pathognomonic pattern and US proved to be a quick, noninvasive and cost-effective technique to confirm clinical diagnosis. The nodule is typically single and iso echoic, with maximum diameter of about 1 cm, inhomogeneous internal structure and few thin hyperechoic septa. The nodular fibrous proliferation adheres with the major axis along the plantar fascia; it exhibits clear-cut margins and US beam transmission is good. No calcifications or fluid collections are seen within the nodule. Color and power Doppler show no flow inside. It is demonstrated that US is an adequate tool for the study of plantar fibromatosis. [Italian] Negli anni 1998-99 sono stati osservati ben sei casi di fibromatosi plantare, solo in parte trattati chirurgicamente.

    2015-01-01

    Full Text Available Fibromatosis is benign fibrous tissue condition intermediate between benign fibroma and metastasizing fibrosarcoma. The lesion tends to infiltrate and recur when removed, but do not metastasize. The lesion may be single or multiple, and the likelihood of recurrence after surgical removal varies with location of the lesion and age. A 40-year-old female presented with multiple raised lesions over both feet since 4 years, they were multiple well-defined firm nodules coalescing to form lobulated plaques distributed in a symmetrical pattern over the dorsum of both feet. Histopathology of skin showed epidermis with hyperkeratosis, acanthosis, mild parakeratosis, and prominent granular layer. Superficial dermis was unremarkable and deep dermis showed thick bundles of irregular collagen and fibroblastic proliferation, suggestive of fibromatosis. This case is being reported for its unusual presentation of fibromatosis over the dorsum of both feet.

    Full Text Available A 41-year-old man was discovered to have a pelvic mass during investigation for hypertension 2 years ago. Otherwise, he was asymptomatic, and abdominal magnetic resonance imaging revealed a highly vascular solid mass superior to the urinary bladder. A 131I-meta-iodobenzylguanidine whole body scan was reported as normal, which ruled out the possibility of extra-adrenal pheochromocytoma. No definitive preoperative diagnosis could be established. Surgical resection of the tumour revealed mesenteric Castleman's disease, hyaline vascular type. Such a diagnosis should be considered for any abdominal vascular mass.

    Full Text Available Abstract Introduction Chronic mesenteric ischemia is a condition that is classically associated with significant atherosclerosis of the abdominal arteries, causing postprandial abdominal pain out of proportion to physical examination. The abdominal pain is exacerbated after meals due to the shunting of blood away from the intestines to the stomach, causing relative ischemia. More than 95% of chronic mesenteric ischemia cases are due to atherosclerosis. We report the first known case of chronic mesenteric ischemia from fibromuscular dysplasia. To the best of our knowledge, this is also the first known case in the literature where postprandial abdominal pain was the presenting symptom of fibromuscular dysplasia. Case presentation A 44-year-old Caucasian woman with a history of hypertension and preeclampsia, who had taken oral contraceptive pills for 15 years, presented with an intractable, colicky abdominal pain of two weeks duration. This abdominal pain worsened with oral intake. It was also associated with diarrhea and vomiting. Physical examination revealed stage III hypertension out of proportion to her risk factors and diffuse abdominal pain without peritoneal signs. An abdominal computed tomography scan, completed in the emergency room, revealed nonspecific colitis. Laboratory work revealed leukocytosis with a left shift, an erythrocyte sedimentation rate of 79 and a C-reactive protein level of 100. She was started on intravenous flagyl and intravenous ciprofloxacin. However, all microbial cultures were negative including three cultures for clostridium difficile. Urine analysis revealed nephritic range proteinuria. The laboratory profile was within normal limits for perinuclear-anti-neutrophil cytoplasmic antibody, cytoplasmic-anti-neutrophil cytoplasmic antibody, anti-saccharomyces cerevisiae antibody, antinuclear antibody test, celiac profile, lactate, carbohydrate antigen-125 and thyroid stimulating hormone. A colonoscopy was completed

    Full Text Available A 9-day-old male baby was hospitalized after his birth due to some swells under the skin. The hard consistency nodules observed under the skin all over the body of the patient were of different size, and presented lesions, among which the biggest was 1 × 1 cm. No lesions were observed on the fingers. By superficial ultrasonography, multiple isoechoic hypoechoic lesions were observed among the muscle plan. In thoracolumbar magnetic resonance imaging, multiple massif lesions retaining peripheral contrast (the biggest was 1.7 × 1.4 cm large had been observed under the skin muscle plans, between the muscles of the extremities. The biopsy was positive for smooth muscle actin, but negative for desmin, S100, and CD34. These findings were diagnosed as infantile digital fibromatosis (IDF (inclusion body fibromatosis. The case was presented with an objective to illustrate and remind that IDF can be observed in babies without finger involvement.

    Full Text Available Introduction: Cisplatin is a platinum-based chemotherapeutic agent, widely used in cancer therapies for numerous solid tumours. It is becoming more recognised that a potentially life-threatening complication of cisplatin is accelerated arterial and venous thrombosis. Presentation of case: We describe a case of a 62 year-old with no risk factors for vascular disease who presented with thromboembolic acute mesenteric ischaemia of the small bowel during treatment with cisplatin for head and neck cancer. Discussion: We review the literature on the incidence and pathogenesis of cisplatin induced arterial thrombosis and discuss current treatment options of acute mesenteric ischaemia detailing our management of this case. Conclusion: Cisplatin increases the risk of arterial thrombosis and this case report details acute mesenteric ischaemia secondary to its use. We hope to raise clinician awareness of this sequelae which can occur even in patients in the absence of other identifiable risk factors.

    Full Text Available Background: Mesenteric cysts are rare intra-abdominal masses in the paediatric age group with varied presentation, ranging from an asymptomatic mass to acute abdomen. This study reviews our experience in the diagnosis and treatment of 17 mesenteric cysts in our centre, with especial reference to acute abdominal symptoms. Patients and Methods: Seventeen patients (age less than 10 years with mesenteric cysts were managed in our hospital. The age ranged from 15 days to 10 years. Patients were admitted with acute or chronic symptoms. They were evaluated with complete history, clinical examination, blood investigations and radiological investigations (x-ray abdomen erect, ultrasound abdomen (USG and computed tomography (CT scan in selected cases to reach a provisional diagnosis. The diagnosis was proven on laparotomy and histologically confirmed. Results: The main presenting symptoms were abdominal pain or lump. The most common mode of presentation was acute small intestinal obstruction. USG was not conclusive in all. Abdominal CT scan with intravenous contrast was diagnostic in nine patients. Five patients had volvulus on exploration. Cysts were located in small intestinal mesentery in 14 cases and three were in the sigmoid mesentery. Seven patients had complete excision, intestinal resection was required in four and marsupialisation with cauterisation of margins was done in six patients. Histologically, all were lymphangiomatous mesenteric cysts. Conclusion: The diagnosis of mesenteric cysts should be kept in mind in any patient presenting with acute abdominal symptoms. Small bowel volvulus with mesenteric cyst constituted a significant number in children with acute abdominal symptoms. Early diagnosis and treatment yields excellent outcome.

    A case of mesenteric vein thrombosis presenting as gastrointestinal hemorrhage in a patient with Klinefelter's syndrome is reported, an association not previously described. The diagnosis was made preoperatively and was confirmed by angiography. The patient underwent a small bowel resection and made an uneventful recovery. A possible association between Klinefelter's syndrome and a hypercoagulable state, previously suggested elsewhere, is emphasized.

    Acute mesenteric vein thrombosis (MVT) is defined as new-onset thrombosis of the mesenteric vein without evidence of collateralization, finally resulting in extensive intestinal infarction. MVT may be idiopathic or be caused by conditions responsible for thrombophilia and acquired risk factors. To date, there have been few reports of MVT after trauma. Herein we describe our experiences treating three patients with MVT. Case 1 was a 44-year-old man with transverse colon mesenteric hematoma after blunt abdominal trauma. Case 2 was a 55-year-old man with jejunal transection after a traffic accident. Case 3 was a 26-year-old man presented with multiple abdominal stab bowel injury. A 1-week follow-up abdominal computed tomography scan showed superior mesenteric vein thrombosis in all of three patients. All patients were treated with anticoagulant for 3 or 6 months. MVTs were completely resolved without any complications. If early diagnosis and treatment could be available, anticoagulation alone might be adequate for the treatment of SMVT associated with trauma. Early anticoagulation in patients with acute SMVT may avoid the grave prognosis observed in patients with arterial thrombosis. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc.

    Full Text Available Abstract Background and method The aim of this study was to assess retrospectively the clinical presentation, management and outcome of three patients with isolated SMA dissection encountered at Okinawa Prefectural Chubu Hospital, Japan from 2005 to 2006, along with a review of the literature. We follow up the patient's clinical symptoms and the image by using enhanced dynamic CT at 1 week, 1 or 2 months, 6 months, and yearly after onset. Case presentation We present three patients with acute abdominal pain due to spontaneous dissection of the superior mesenteric artery (SMA, who were treated by surgical revascularization or conservative management. Two patients underwent surgery because of signs or symptoms of intestinal ischemia and one patient elected conservative management. The SMA was repaired by bypass graft in two cases, and in one of these, the graft was occluded because of prominent native flow from the SMA. All patients were symptom free and there was no evidence of disease recurrence after a median follow-up of 4.3 years. Conclusion Although the indications for surgery are still controversial, we should proceed with exploratory laparotomy if the patient has acute symptoms with suspicion of mesenteric ischemia. A non-operative approach for SMA dissection requires close follow-up abdominal CT, with a focus on the clinical signs of mesenteric ischemia and the vascular supply of the SMA, including collateral flow from the celiac artery and inferior mesenteric artery.

    Mid-gut volvulus is a rare complication of pregnancy, where torsion of the small bowel around its mesentery can result in extensive bowel infarction. To our knowledge, there has been no previous reported case of mid-gut volvulus and mesenteric vessel thrombosis managed without bowel resection. A 25-year-old woman presented at 35 + 3 weeks gestation with constant abdominal pain. There was no past medical history of abdominal surgery. The patient later developed feculent vomiting. Exploratory laparotomy revealed a mid-gut volvulus causing small bowel ischaemia, which extended from the duodenojejunal (DJ) flexure to the terminal ileum. There was also mesenteric arterial and venous thrombosis. A healthy baby girl was delivered by caesarean section and the mid-gut volvulus was reduced. Further, two re-look laparotomies confirmed viable bowel following detorsion. The mesenteric vessel thrombosis was treated with intravenous heparin. The patient went on to make a full recovery. As shown in this case, the volvulus and mesenteric vessel thrombosis may occur during pregnancy even in patients without previous history of coagulopathies and abdominal surgery. It is difficult to make a clinical diagnosis, as the symptoms, physical signs and laboratory findings can be misleading. Therefore, a high index of suspicion is necessary for the early diagnosis of these conditions, as prompt treatment can prevent bowel resection and improve maternal and foetal outcomes.

  15. Superior Mesenteric Vein Occlusion Causing Severe Gastrointestinal Haemorrhage in Two Paediatric Cases

    Directory of Open Access Journals (Sweden)

    Anna L. Fox

    2012-01-01

    Full Text Available Reports about superior mesenteric vein thrombosis in childhood are very rare and have not been associated with gastrointestinal bleeding. We describe two cases of severe bleeding from the upper and lower gastrointestinal tract in children who had undergone complex abdominal surgery at considerable time before. The first child had a tracheoesophageal fistula, corrected by division, gastrostomy insertion, and repair of duodenal rupture. The child presented with severe bleeding from the gastrostomy site and was diagnosed with a thrombosis of the proximal superior mesenteric vein. The second child had a gastroschisis and duodenal atresia, and required duodenoplasty, gastrostomy insertion, hemicolectomy, and adhesiolysis. The child presented with intermittent severe lower gastrointestinal bleeding, resulting from collateral vessels at location of the surgical connections. He was diagnosed with a thrombosis of the superior mesenteric vein. In both children, the extensive previous surgery and anastomosis were considered the cause of the mesenteric thrombosis. CT angiography confirmed the diagnosis in both cases, in addition to characteristic findings on endoscopy. Paediatricians should suspect this condition in children with severe gastrointestinal bleeding, particularly in children with previous, complex abdominal surgery.

    2010-05-01

    Full Text Available Abstract Introduction Cases of right paraduodenal hernia and superior mesenteric artery syndrome have been reported separately, but their occurrence in combination has not been reported. Case presentation A 46-year-old Japanese man who had never undergone laparotomy was admitted to our hospital due to an acute abdomen. An enhanced multidetector-row computed tomography scan of our patient showed a cluster of small intestines with ischemic change in his right lateral abdominal cavity. Emergency surgery was subsequently performed, and strangulation of the distal jejunum along with incidental right paraduodenal hernia was found. His necrotic ileum was resected, and the jejunum encapsulated by the sac was repaired manually without reduction. Three days after the operation, however, our patient developed vomiting. An upper gastrointestinal series revealed a straight line cut-off sign on the third portion of his duodenum. A second enhanced multidetector-row computed tomography scan showed that he had a lower aortomesenteric angle and a shorter aortomesenteric distance compared to his condition before his right paraduodenal hernia was surgically repaired. We strongly suspected that the right paraduodenal hernia repair may have induced superior mesenteric artery syndrome. On the 21st post-operative day, duodenojejunostomy was performed because conservative management had failed. Conclusions In this case, enhanced multidetector-row computed tomography, which permits reconstructed multiplanar imaging, helped us to visually identify these diseases easily. It is important to recognize that surgical repair of a right paraduodenal hernia may cause superior mesenteric artery syndrome.

    Full Text Available Background. Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren` s disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose`s disease or plantar fibromatosis is plantar equivalent of Dupuyten`s disease most often affecting middle- aged and older men, usually bilateral, represented with painless nodule in the medial division of plantar fascia. Case report. We presented a 19-year old adolescent that turned to a plastic surgeon complaining to his small finger contracture. He noticed palmar thickening with nodule over the metacarpophalangeal joint of small finger of his right hand when he was 16 years old. A year later a finger started to band. During physical checkup we noticed plantar nodule that also had his father and grandmother. Magnetic resonance and tumor biopsy confirmed a suspicion on plantar fibromatosis - Ledderhose`s disease. Clinical exam of the hand clearly led to a conclusion that the patient had Dupuytren`s contracture with pretendinous cord over the small finger flexor tendons and lack of extension of proximal interphalangeal (PIP joint. On the extensor side of the PIP joints there were Garrod`s nodes. The patient refused surgical treatment of plantar tumor, but agreed to surgical correction of finger contracture. Conclusion. Despite the fact that Dupuytren`s disease and plantar fibromatosis are diseases of adults, the possibility of conjoint appearance of these forms of fibromatosis in adolescent period of life should be kept in mind especially in patients with strong genetic predisposition.

    Full Text Available We present a case of acute mesenteric venous thrombosis after a long distance flight in a traveller presenting with abdominal pain, diarrhoea and vomiting within 48 h of prolonged immobility situation. Venous thrombosis in the lower limbs and venous thromboembolism has been clearly associated with prolonged air travel (economy class syndrome. Thrombosis was diagnosed by computed tomography of the abdomen, and after starting anticoagulant therapy with acenocumarol, symptoms yielded completely in a few weeks. The study of thrombophilia was negative, although the existence of two first-degree relatives (mother and grandmother with a history of venous thrombosis with a history of venous thrombosis makes it likely a situation of inherited thrombophilia. Although exceptional, mesenteric venous thrombosis should be considered in travellers with acute abdominal pain after prolonged air travel when there are thrombophilic conditions.

    Full Text Available Abstract Introduction Mesenteric panniculitis of the sigmoid colon is a rare occurrence in surgical practice. The aim of this article is to present a case of mesenteric panniculitis of the sigmoid colon and a short review of the literature. Case presentation We reviewed the hospital record of a 63-year-old man who presented with a palpable mass in the left abdomen and clinical signs of a partial bowel obstruction. The pre-operative impression was a possible cancer of the sigmoid colon. A laparotomy was performed through a midline incision. The mesentery was found to be markedly thickened, constricted and puckered. The normal architecture of the adipose tissue had been lost and replaced with an irregular nodular mass. The microscopic pathologic sections demonstrated a chronic reactive inflammatory process with an exuberant proliferation of fibroblasts and fibrocytes. The adipose tissue contained scattered areas of steatonecrosis with foci of lipid-laden macrophages, lymphocytes and plasma cells. The sigmoid colon and its mesocolon were resected. The postoperative course was uneventful and the patient was discharged in good condition, and followed up for the next two years. Conclusion Mesenteric panniculitis of sigmoid is an extremely rare entity of unknown origin in which the normal architecture of the mesentery is replaced by fibrosis, necrosis and calcification. On gross examination the alterations may be mistaken for a neoplastic process. A frozen section may be necessary for confirmation of the diagnosis. When the advanced inflammatory changes became irreversible and bowel obstruction occurs, resection may be indicated.

    Chronic mesenteric ischemia (CMI) is a rare disorder caused by severe stenosis of the mesenteric arterial supply that results in postprandial pain and weight loss. Treatment options are surgical or endovascular. Surgical bypass can be performed in an antegrade fashion from the supraceliac abdominal aorta (AA) or the distal descending thoracic aorta or in a retrograde fashion from the infrarenal aorta or the common iliac artery. However, in some patients with disease of the descending thoracic aorta or the AA, another site for the proximal anastomosis needs to be found. In this article, we report the case of a 69-year-old man with a thoracoabdominal aortic aneurysm and CMI in whom we performed bypass grafts to the hepatic and superior mesenteric arteries using the ascending aorta as the site for the proximal anastomoses via a median sternolaparotomy. In addition, we performed a literature review of all similar cases and provide an analysis of this technique and an assessment of the success rates. Copyright © 2016 Elsevier Inc.

    We report three cases of mesenteric panniculitis in which the disease took different courses. The first case clinically mimicked an acute diverticulitis and consequently laparotomy was performed. During this operation a large space-occupying tumour was found in the lower abdomen. After resecting this tumour mass of uncertain classification (benign or malignant) a preternatural anus of sigmoid colon was formed. Histological exploration revealed mesenteric panniculitis. Six months later we restored continuity of large bowel by end-to-end anastomosis. No residues of the preexisting panniculitic alterations were seen. The second case concerned a female patient who again complained of discomfort after surgical treatment of colon carcinoma. We measured an elevated erythrocyte sedimentation rate and suspected a relapse of the malignant disease. Notwithstanding radiological and endoscopic diagnostics, the origin and classification of an intra-abdominal tumour could not be determined preoperatively. Laparoscopically we took a biopsy of the local mass, but a definite diagnosis was not found. Postoperatively undulant fever occurred, uninfluenced by cortisone treatment. Finally the patient died because of unstoppable hemorrhage under coagulopathy. Mesenteric panniculitis was identified as causative disease by autopsy.

    Full Text Available Pylephlebitis is an uncommon complication of uncontrolled intra-abdominal infection that is associated with high morbidity and mortality. We present our experience with a unique case of cecal diverticulitis and septic thrombophlebitis of the superior mesenteric vein that was promptly diagnosed with high-resolution imaging and blood cultures. Antibiotic and anticoagulation therapy was instituted on confirming the diagnosis with magnetic resonance imaging (MRI to control the infection and prevent propagation of the thrombus. Our case report raises awareness about a rare and potentially fatal condition and provides appropriate imaging supplementation to aid in timely diagnosis.

    2009-01-01

    In evaluating the long-term intensive treatments essential for short bowel syndrome, we analyzed 10 cases of acute superior mesenteric arterial (SMA) occlusion. Abdominal CT scan detected a smaller superior mesenteric vein (SMV) sign in five out of seven cases, which was useful in making preoperative diagnosis even in noncontrast-enhanced CT. The greater part of the small intestine and part of the colon which became necrotic were resected in all 10 cases. Six patients who were able to be eventually discharged from the hospital had a mean residual jejunum length of 75 cm. Four patients requiring no parenteral nutrition had a mean intestinal length of 95 cm, compared to 35 cm for the two still requiring parenteral nutrition. We report here a case of a 68-year-old man with a 20-cm residual jejunum after surgery for SMA occlusion. He has been unable to eat orally and requiring total parenteral home nutrition, and suffered from catheter infection requiring 24 catheter replacements. Despite survival exceeding for more than 5 years, longer than that of reported cases so far, his quality of life is not necessarily good. (author)

    Full Text Available Abstract Background A number of non-malignant diseases that share similar morphological features as gastrointestinal stromal tumor (GIST have been reported. Co-existence of GIST with these other diseases is rarely recognized or reported. Case presentation We report a case of a 62 year-old man with long-term stable control of metastatic GIST with systemic therapy, presented with an apparent intra-abdominal progression but not supported by imaging with positron emission tomography. Subsequent resection of the intra-abdominal tumor identified a non-malignant fibroid. Conclusion Differentiating localized progression of GIST from other diseases has important prognostic and therapeutic implications. The potential for co-existence of non-malignant soft tissue neoplasm should always be considered.

    A retrospective study of all patients presenting with abdominal malignancies since November 1982 was undertaken in order to assess the CT features of peritoneal and mesenteric involvement in childhood. Thirteen cases, including 4 cases of malignant lymphomas, 1 case of Hodgkin's disease, 5 cases of adrenal tumors and 3 cases of ovarian tumors, were selected. Providing a good technique, CT appears as the best imaging modality of the mesentery. CT is also reliable in showing peritoneal implants, even without ascites. A high quality vascular opacification is needed in order to recognize the involvement of the lesser omentum (6/13 cases in our series). Precise knowledge of the intra-abdominal extension of the primary neoplasm has a definite impact upon the surgical indications and therefore upon the prognosis [fr

    Isolated spontaneous dissection of the superior mesenteric artery (SMA) is a comparatively rare disease, and symptoms vary from acute to chronic abdominal pain to no symptoms. However, it is difficult to diagnose; there is no consensus about medical treatment and the long-term consequences. Isolated spontaneous dissection of the SMA was believed to be a rare disease that required conventional surgery for treatment; however reports of SMA dissection have increased with the progression of diagnostic imaging, and surgery may not always be required. We reviewed 10 cases of isolated spontaneous dissection of the SMA that we experienced between January 1998 and December 2008. We performed conservative medical treatment with anticoagulants in 5 cases, advised bed rest in 4 cases, and performed endovascular treatment in 1 case. None of the cases needed surgery for treatment. There were 3 cases that required continuous administration of long-term anticoagulants or antiplatelet agents. There were no recurrences in a 4-year average observation period. (author)

    2012-01-01

    Full Text Available We present a case of a man with amyotrophic lateral sclerosis who developed superior mesenteric artery syndrome (SMAS following the confection of feeding jejunostomy. He was successfully managed by conservative treatment. Left lateral positioning during enteral feeding allowed quick resolution of the occlusive state. Various surgical interventions have been associated with SMAS, directly or indirectly, by reducing the width of the aortomesenteric angle. The operative stress was probably what triggered symptomatology in our patient thus to conclude that the surgical stress should be considered as a causal factor triggering the SMAS in a context of other predisposing factors.

    2009-09-01

    Full Text Available Abstract Introduction Small intestinal strictures secondary to mesenteric vessel thrombosis are a rare entity and thus often result in delayed diagnosis. We present two cases of ischaemic small bowel strictures secondary to mesenteric vessel thrombosis, and describe how they were subsequently managed. Case presentation We present two cases of abdominal pain, one acute and one chronic, in which the eventual diagnosis was of bowel strictures secondary to arterial and venous vessel thrombosis. In both patients, a Caucasian male aged 67 and a Caucasian female aged 78, the diagnosis was delayed because of the infrequency of their presentation. Both patients eventually underwent a resection of the affected portion of bowel with primary anastamosis and made uneventful recoveries. Conclusion There are multiple medical and surgical management options for small bowel strictures and these depend on the aetiology of the stricture. Ischaemic small bowel strictures represent a difficult diagnosis and the potential resulting delay may be partially responsible for increased morbidity. Barium small bowel follow-through should be used in making the diagnosis.

    Hyaline fibromatosis syndrome (HFS) is a rare, homozygous, autosomal recessive disease, characterized by deposition of hyaline material in skin and other organs, resulting in esthetic problems, disability, and potential life-threatening complications. Most patients become clinically apparent in the first few years of life, and the disorder typically progresses with the appearance of new lesions. We describe a rare case of a 20-year-old patient with juvenile-onset mild HFS who presented with a history of progressive anterior knee pain. Detailed magnetic resonance (MR) imaging findings with histopathological correlation are presented of hyaline fibromatosis of Hoffa's fat pad, including differential diagnosis. The diagnosis of HFS is generally made on basis of clinical and histopathological findings. Imaging findings, however, may contribute to the correct diagnosis in patients who present with a less typical clinical course of HFS. (orig.)

    Acute portomesenteric vein thrombosis is an uncommon but serious condition with potential sequelae, such as small-bowel gangrene and end-stage hepatic failure. It is known to be caused by various pro-thrombotic states, including hyperhomocysteinemia. We describe what is, to the best of our knowledge, the first reported case of concomitant thrombosis of portal, superior mesenteric and splenic veins due to hyperhomocysteinemia secondary to pernicious anemia and no other risk factors. A 60-year-old Indian man presented with epigastric pain, diarrhea and vomiting. An abdominal imaging scan showed that he had concomitant pernicious anemia and concomitant portal, superior mesenteric and splenic vein thrombosis. A work-up for the patient's hypercoagulable state revealed hyperhomocysteinemia, an undetectable vitamin B12 level and pernicious anemia with no other thrombophilic state. He developed infarction with perforation of the small bowel and subsequent septic shock with multi-organ dysfunction syndrome, and he ultimately died due to progressive hepatic failure. This report demonstrates that pernicious anemia, on its own, can lead to hyperhomocysteinemia significant enough to lead to lethal multiple splanchnic vein thrombosis. Our case also underscores the need to (1) consider portomesenteric thrombosis in the differential diagnosis of epigastric abdominal pain, (2) perform a complete thrombotic work-up to elucidate metabolic abnormalities that could be contributing to a pro-thrombotic state and (3) initiate aggressive measures, including early consideration of multi-visceral transplantation, in order to avoid decompensation and a significant adverse outcome.

    Full Text Available Introduction: In the treatment of portal hypertension in pediatric patients, some type of porto-systemic shunt is indicated, which is an unusual surgical procedure in patients under two years of age, due to the low incidence of this disease at this age and the increase in the number of complications. Objective: We present our experience and results with this procedure in patients under two years of age seen in the Hepatobiliopancreatic general surgery service at Instituto Nacional de PediatríaDiscussion: The causes of portal hypertension in children are varied. Among the extrahepatic causes, the most common is cavernomatous portal degeneration. Children with portal hypertension under two years have severe symptoms such as recurrent gastrointestinal bleeding or anemia; others have hypersplenism data. In many cases medical management is useless and a surgical procedure require such as a portosystemic shunt in order to decrease the size of varicose esophageal veins and prevent bleeding that threatens the patient’s life. Conclusion: The iliac-mesenteric-caval shunt in patients under two years is a feasible alternative that improves the clinical status of the patient, reducing the risk of bleeding. However long-term studies are needed to determine the outcome of these patients. Keywords: Iliac-mesenteric-caval shunt, portal hypertension.

    The authors describe three cases of intraabdominal fibromathosis: two cases with intraperithoneal location and another one with retroperithoneal location. All of them are benign noncapsulated tumours of the fibrous tissue with tendancy to local recurrence. Abdominal fibromathosis may determine any form of acute or chronic digestive manifestations. Only to the accuracy of the histo-pathological examination is due the diagnosis between fibromathosis and fibrosarcoma, reactive fibrosis, mixoma and nodular fasceitis. The surgical excision must not be economical and the association with radiant therapy must also be considered.

    Sclerosing mesenteritis is a rare benign process that involves inflammation, fat necrosis, and fibrosis of the mesentery. The disease poses great diagnostic challenge due to its nonspecific clinical and diagnostic findings. We report the case of a 75-year-old man who presented with vague abdominal discomfort associated with an intra-abdominal mass. With suspicion of a bowel carcinoid tumor on computed tomography scans, the patient underwent diagnostic laparoscopy. A diagnosis of sclerosing mesenteritis was made on histological examination. The patient's symptoms responded to a combination of immunosuppressive drugs, with no interval change in the size of the mass on radiological examination after fifteen months. PMID:20671922

    Venous thrombosis is common in nephrotic syndrome, but portal vein thrombosis has a relatively low incidence in patients with nephrotic syndrome. We describe here a case of an 18-year old male student with newly diagnosed nephrotic syndrome that was complicated with portal, splenic and superior mesenteric vein thrombosis. In the presence of newly diagnosed nephrotic syndrome of minimal change disease, thrombus formation can occur and should be noted, particularly when it occurs, in rare sites. The recognition in nephrotic syndrome complicated with portal, splenic and superior mesenteric vein thrombosis should be emphasized.

  19. Small-bowel necrosis complicating a cytomegalovirus-induced superior mesenteric vein thrombosis in an immunocompetent patient: a case report

    Science.gov (United States)

    2012-01-01

    Introduction Superior mesenteric venous thrombosis as a result of acute cytomegalovirus infection is rare, with only a few cases reported in the literature. Case presentation We present the case of a 40-year-old Caucasian man who was admitted to our hospital with a 5-day history of fever. His serological test and pp65 antigen detection of cytomegalovirus were positive, suggesting acute infection. On the sixth day after his admission, the patient complained of acute, progressive abdominal pain. Abdominal computed tomography revealed acute superior mesenteric venous thrombosis. An emergency laparotomy showed diffuse edema and ischemic lesions of the small bowel and its associated mesentery with a 50-cm-long segmental infarction of the proximal jejunum. An extensive enterectomy of about 100 cm of jejunum that included the necrotic segment was performed, followed by an end-to-end anastomosis. Anti-coagulation therapy was administered pre-operatively in the form of small-fractionated heparin and continued postoperatively. The patient had an uneventful recovery and was discharged on the 11th postoperative day. Conclusion Acute cytomegalovirus infection can contribute to the occurrence of mesenteric venous thrombosis in immunocompetent patients. It is important for physicians and internists to be aware of the possible thrombotic complications of cytomegalovirus infection. A high level of clinical suspicion is essential to successfully treat a potentially lethal condition such as superior mesenteric venous thrombosis. PMID:22531275

    Full Text Available Cavitating mesenteric lymph node syndrome (CMLNS is a rare complication of celiac disease. Globally, only 36 cases of CMLNS have been reported to date. The present article reports an incidence of its unique pathology and possible complications of celiac disease, followed by a review of the syndrome. A case involving a 51-year-old man with celiac disease who was referred to hospital because of a non-tender abdominal mass is described. Plain film x-ray of the abdomen revealed fine curvilinear calcifications in the left lower quadrant. A complex, cystic-appearing, lobulated mass with somewhat echogenic walls most consistent with calcifications was revealed on subsequent ultrasound (US imaging. Colour Doppler imaging showed no evidence of vascularity within the lesion. Computed tomography (CT imaging showed a thin rim of calcification in the walls of multiple cystic components. Enhanced magnetic resonance (MR imaging revealed a mixed solid and cystic multiloculated mass, with fat-fluid layers originating from the root of the small bowel mesentery. A CT-guided biopsy was performed. The fine-needle aspirate revealed calcified matter with no associated cellular material. No malignant cells were seen; CMLNS was established as the diagnosis. To the authors’ knowledge, there are no previous reports in the literature describing the finding of rim calcification on US or MR imaging in the setting of CMLNS. CMLNS is an important diagnosis to consider, particularly in patients with a history of celiac disease. The finding of rim calcification on US in the setting of cavitating mesenteric adenopathy should prompt further diagnostic imaging studies such as CT or MR imaging. These may lead to additional pathology studies such as a CT-guided biopsy to further characterize the lesion at the cellular level, to investigate potential malignancy and to further guide follow-up and patient management.

  1. Infantile Fibromatosis: A Rare Cause of Anterior Mediastinal Mass in a Child

    2015-01-01

    Full Text Available Fibromatosis also known as desmoid tumor is an uncommon cause of a mediastinal mass in patients of all ages. Imaging appearance of fibromatosis is generally nonspecific and demands special attention to subtle details to be correctly identified as a possibility. Management of the patient is often complicated by failure to obtain precise pre-operative diagnosis. Location of a mass in the anterior mediastinum with encasement of vital structures is not favourable for complete cure. Although histologically benign, biological behaviour of the lesion varies between benign fibrous proliferation and low-grade fibrosarcoma. We present imaging appearances, surgical management dilemma, and the histopathological details of a case of fibromatosis in the anterior mediastinum in a child.

    Full Text Available Fibromatosis colli is an uncommon benign, congenital fibrous tumor or pseudotumor of the sternocleidomastoid muscle that manifests in infancy. In some of these patients tightening of the muscle results in torticollis. We report the case of a 3-week-old child, who presented with a neck mass localized in the left side with reduced mobility of the head. The diagnosis of fibromatosis colli was raised by ultrasound sonography. The mass regressed spontaneously within 3 months without surgical or physical treatment.

    We have experienced an unusual case of mesenteric lymphangiomatosis in a 6-month-old male infant. Computed tomography (CT) disclosed fatty abdominal masses with attenuation coefficient being -5∼-28 Hounsfield units (HU). Laparotomy disclosed innumerable small and large chyle containing masses in the mesentery as well as mesenteric root. Pathologically these were confirmed to be cavernous and cystic lymphangiomatosis. One must bear in mind the possibility of lymphangioma in case of fat containing mesenteric mass on CT

    Mesenteric phlebosclerosis is a rare ischemic disease affecting the colon. Systemic disease and herbal medicine have been pointed out as possible causes, and the disease is characterized by calcifications involved the mesocolic veins. Patients who do not respond to conservative therapy require surgical treatment. In surgical intervention, an adequate extent of colonic resection is important. We present a case of an 87-year-old woman with mesenteric phlebosclerosis who had consumed herbal medicine for 40 years. She suffered from ileus caused by mesenteric phlebosclerosis, and the symptoms did not improve with conservative therapy. Right hemicolectomy was performed since the disease was localized in the right colon. Long-term use of herbal medicine was considered the potential cause of mesenteric phlebosclerosis. The postoperative course was mostly uneventful. The patient stopped using herbal medicine and had no signs of recurrence 2 years after surgery. The greatest concern in surgery for mesenteric phleboscrerosis is to detect the affected area, which should be removed. Characteristic findings in computed tomography and intraoperative findings can help to determine the optimal extent of colonic resection. Mesenteric phlebosclerosis caused by herbal medicines occurs as localized disease in the right colon compared with mesenteric phlebosclerosis caused by other pathogenesis. Limited colonic resection is usually indicated for mesenteric phlebosclerosis caused by herbal medicine. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  6. Aggressive Fibromatosis: Evidence for a Stable Phase

    Full Text Available Purpose. Aggressive fibromatosis (AF is an uncommon locally infiltrating benign disease of soft tissue for which treatment comprises complete surgical resection. Radiotherapy can be given postoperatively if the margin is incompletely resected. If the tumour is inoperable radiotherapy provides an alternative treatment. Hormone therapy and cytotoxic chemotherapy have also been used for unresectable or recurrent disease. All treatment modalities carry an associated morbidity. We believe that the natural history of aggressive fibromatosis may include a period of stable disease without progression, during which time, treatment is not always necessary.

    Acute mesenteric ischemia poses a diagnostic challenge due to nonspecific clinical clues and lack of awareness owing to its rarity. Ischemia due to mesenteric venous thrombosis has a good prognosis compared to arterial cause and can be managed conservatively with early diagnosis. The portomesenteric venous system is an unusual site of thrombosis in patients with protein S deficiency, and its thrombosis is an uncommon cause of acute mesenteric ischemia. We present a case of a 27-year-old Mongolian man who presented with acute abdominal pain increasing in severity, and refractory to repeated attempts at treatment with a misdiagnosis of acute peptic ulcer disease. Contrast-enhanced computed tomography of his abdomen detected complete occlusion of the superior mesenteric vein, an extension of acute thrombus into the portal vein, and ischemic mid-jejunal loops. Early diagnosis and immediate anticoagulation with continuous intravenous infusion of unfractionated heparin prevented subsequent consequences. On further workup, our patient was diagnosed with isolated protein S deficiency. We started lifelong thromboprophylaxis with warfarin to prevent recurrence and our patient was asymptomatic on the latest follow-up 5 months after discharge. Despite accurate detection of acute mesenteric ischemia by contrast-enhanced computed tomography, high index of suspicion is indispensable for its early diagnosis. Early diagnosis and immediate anticoagulation will prevent subsequent complications and need for surgical intervention. Young patients without known risk factors presenting with venous thrombosis in atypical sites should be investigated for prothrombotic diseases.

    2014-01-01

    Patient: Male, 69 Final Diagnosis: Mesenteric desmoid tumor Symptoms: — Medication: — Clinical Procedure: — Specialty: Surgery Objective: Rare disease Background: Intra-abdominal fibromatosis is a benign rare tumor of fibrous origin with a significant potential for local invasion and no ability to metastasize, but it can recur. The etiology of desmoid tumors is unknown. It is often associated with conditions such as familial adenomatous polyposis and Gardner syndrome. Case Report: We report the case of a 69-year-old man who presented to our hospital with an acute pulmonary embolism. The patient had a past history of colic surgery for a polyp with a high-grade dysplasia. Pulmonary angiography showed partial occlusion of the right superior lobe artery and partial occlusion of the middle lobe artery. The patient was given thrombolytic therapy. Abdominal computerized tomography revealed a mesenterial giant mass with compression of the inferior vena cava (IVC). A biopsy of the mass, confirming aggressive fibromatosis. A laparotomy was performed, which revealed a massive growth occupying the abdomen and attached to the previous ileocolic anastomosis. One day after surgery, his condition deteriorated. Conclusions: This report underlines the potential of imaging investigations of abdomen and vena cava if pulmonary embolism is suspected, especially when there is no evidence of peripheral venous thrombosis or other predisposing factors. Unfortunately, data on the surgical management of desmoid tumor is scarce. Therefore, the standard of treatment is a surgical resection for resectable tumors. PMID:25180474

    Symptoms related to peripheral embolism are experienced in 2%-15% of cases of cardiac myxoma. We present a rare case of a 54-year-old man admitted due to sudden abdominal pain. A computed tomography (CT) scan showed occlusion of the superior mesenteric artery (SMA). As the patient's response to support treatment was favorable, a non-invasive approach was adopted, with prescription of oral anticoagulation (OAC) therapy. Transesophageal echocardiography revealed a tumor in the left atrium. The cardiac mass was completely removed and diagnosed as myxoma by histopathological analysis. As periodic CT scans showed progressive improvement of blood flow through the SMA, OAC was continued. OAC may have been beneficial due to the nature of emboli originating from a cardiac myxoma: thrombi covering the surface of the tumor. At present, there is no explanation in the literature for the benefits of OAC in patients with embolism associated with cardiac myxoma. Copyright © 2012 Sociedade Portuguesa de Cardiologia.

    Aggressive fibromatosis is a poorly defined, locally aggressive, yet histologically benign fibroblastic proliferative lesion that may occur in the head and neck. The lesion is highly cellular and locally infiltrative and has a propensity to invade and erode bone, compromising vital structures within the head and neck. However, it is not a true malignancy because it does not have malignant cytologic characteristics nor does it metastasize. We present two cases of aggressive fibromatosis occurring in young adult men. The first case involved a rapidly enlarging mass of the anterior maxilla that involved the upper lip, nasal alae, nasal septum, inferior turbinates, and hard palate. The patient underwent incisional biopsy to confirm the diagnosis. Because of difficulty in determining the actual margins of this extensive lesion and the significant morbidity that would have resulted from surgical resection, we elected to treat this patient with chemotherapy and radiation therapy. The second case was an extensive lesion involving the right temporal bone, pterygomaxillary space, and infratemporal, temporal, and middle cranial fossae. Incisional biopsy confirmed the diagnosis. Because of the lack of functional and cosmetic deficits and the unavoidable morbidity of a surgical resection, this patient was treated with radiation therapy. Although wide field resection is the most satisfactory form of treatment, in situations in which this modality would result in unacceptable morbidity or if surgical margins are positive, then radiation therapy and chemotherapy should be considered. Support for these therapeutic modalities is found in larger series of cases outside the head and neck

    Objective: To investigate the effect of Gradient treatment for acute superior mesenteric venous thrombosis (ASMVT). Methods: Clinic data of 68 patients of ASMVT admitted in Department of General Surgery, Jinling Hospital, Medical School of Nanjing University from January 2009 to December 2014 were analyzed retrospectively. There were 50 male and 18 female patients with a mean age of (45±12) years. These patients were conducted by the stepwise treatment model (endovascular treatment-damage control surgery-surgical intensive care-intestinal rehabilitation treatment). Clinical outcomes and complications were compared during the follow-up period. Differences about bowel resection length of endovascular treatment and surgical procedures were evaluated with t test. Results: In the 68 cases, 24 cases were cured simply by endovascular treatment, 19 cases received surgical procedures alone (group surgery). Twenty-five patients received endovascular treatment combined with surgical procedures (group combined), including 6 cases temporary abdominal closure. The overall mortality rate was 2.9% (2/68) during hospitalization. The range of bowel resection of group combined significantly reduced compared with group surgery ((92±14) cm vs . (162±27) cm, t =-2.377, P =0.022). During 1-year follow-up period, 4 cases suffered from short bowel syndrome, whom underwent surgery alone. Conclusions: Early diagnosis and treatment is the key to treatment of ASMVT, the rapid improvement of intestinal ischemia is particularly important for prognosis. Combination therapy significantly save more residual small intestine and avoid short bowel syndrome. The selection of early gradient treatment can significantly reduce the mortality and improve the prognosis of ASMVT patients.

    Superior mesenteric vein thrombosis was identified on computed tomographic scans in six patients. In each case, contrast-enhanced scans showed a high-density superior mesenteric vein wall surrounding a central filling defect. Four fo the six patients had isolated superior mesenteric vein thrombosis. A fifth patient had associated portal vein and splenic vein thrombosis, and the sixth patient had associated portal vein and inferior vena cava thrombosis. One of the six patients had acute ischemic bowel disease. The other five patients did not have acute ischemic bowel symptoms associated with their venous occlusion. This study defines the computed tomographic appearance of mesenteric vein thrombosis.

    There are a number of reports in the literature which describe the association of venous thrombosis with oral contraceptives. Venous thrombosis is a rare form of mesenteric ischemia which may be lethal if not diagnosed and treated quickly. Although the non specificity of clinical signs do not always permit an early diagnosis. The patient, aged 52, with a case history characterized by alteration of the alvus with occasional emission of blood, and abdominal pain. She referred with metrorrhagia of about one year, and was being treated with Ethynylestradiol/Gestodene. A CAT scan with contrast showed the signs of thrombosis in the superior mesenteric vein. The patient underwent surgical laparotomy. On opening the peritoneum we found a large tumefaction formed of conglobate iliac loops together with intense inflammation. A resection of the tumefaction was performed "en bloc". Pharmacological contraception remains in various cases as the only identified risk factor and there are reports which also censure a relationship of greater risk with increased hormonal doses and even reports of mesenteric venous thrombosis in patients taking triphasic drugs. Thus, we may state with near certainty, that a relationship between pharmacological contraceptives and mesenteric venous thrombosis exists and is probably more than a simple risk factor in contrast to that which exists for tobacco smoking and obesity. Before the prescription of contraceptive therapy the examination of risk factors is necessary, compiled preferably by hematochemical screening to exclude haematological and/or coagulative pathologies, and not deriding the use of non-pharmalogical methods of contraception when possible. Considering the technological advancement of instrumentation (CAT scan, angiogram), even a diagnosis aimed at a suspected clinical history; starting from less invasive screening by ultrasonographic Doppler, might induce to a rapid intervention and thereby avoid sacrificing too much intestinal tissue

    To evaluate the clinical, radiological and histological factors that can predict local recurrence of fibromatosis. A retrospective study was conducted on 51 patients diagnosed with fibromatosis in this hospital from 1983 to 2014. The mean follow-up was 83 months. A study was made of the clinical parameters, location, depth, size, surgical margins, and proliferation index (Ki-67). An evaluation was also made of the risk of recurrence depending on the adjuvant treatment and the relationship between treatment and patient functionality. Tumour location and depth were identified as risk factors for local recurrence, showing statistically significant differences (P<.001 and P=.003, respectively). There were no statistically significant differences in age, gender, size, surgical margins, or adjuvant treatments, or in the Musculoskeletal Tumour Society Score according to the treatment received. The mean Ki-67 was 1.9% (range 1-4), and its value was not associated with the risk of recurrence. Deep fibromatosis fascia tumours, and those located in extremities are more aggressive than superficial tumours and those located in trunk. The Ki-67 has no predictive value in local recurrence of fibromatosis. Radiotherapy, chemotherapy, or other adjuvant treatments such as tamoxifen have not been effective in local control of the disease. Given the high recurrence rate, even with adequate margins, a wait and see attitude should be considered in asymptomatic patients and/or stable disease. Copyright © 2017 SECOT.

    Full Text Available Upper digestive bleeding due to rupture of esophageal varices is asevere complication of portal hypertension in cirrhotic patients. Whenit is associated with portal vein thrombosis, transjugular intrahepaticportosystemic shunt or endoscopic procedures are difficult and lesseffective. In this situation, splenorenal shunt is a good alternative.The aim was to discuss a distal splenorenal shunt with autologousinferior mesenteric vein graft. We report a case of a male patient, 52years old, suffering from alcoholic hepatic cirrhosis and portal veinthrombosis. He had nine episodes of upper digestive bleeding, in spiteof endoscopic treatment. His hepatic function remained good and distalsplenorenal shunt was chosen as the best therapeutic option. Theinferior mesenteric vein was used as an interposition graft for distalrenal shunt due to unexpected events during splenic vein dissection.Postoperative recovery went uneventfully.

We report an 18-month old boy presenting with a palpable intraabdominal mass arising from the ileum mesentery. Histopathologic and cytogenetic studies confirmed the diagnosis of mesenteric lipoblastoma (or infantile lipoma. Complete excision of the mass was performed. A follow-up examination consisting of physical examination and an abdominal ultrasound at 30 months postoperatively revealed no recurrence. We also present a review of the English literature regarding the presentation and management of mesenteric lipoblastomas in children.

    Extra-adrenal paraganglioma is a rare tumor arising from the neural crest cells. Most tumors that develop in the abdomen arise from paraganglia along the paravertebral and para-aortic areas, in particular the organ of Zuckerkandl, which is close to the origin of the inferior mesenteric artery. However, extra-adrenal paraganglioma also occurs in relatively rare places such as the urinary bladder, gallbladder, hepatoduodenal ligament, and gastrointestinal tract. Here, we report imaging findings of extra-adrenal paragangliomas presenting as mesenteric and pararectal masses with lymph node metastasis.

    The sonographic and CT findings of fibromatosis colli (sternomastoid tumor of infancy) have been described, but the MRI appearance has been reported in only one case in which the mass resolved over time. This case describes the detailed MRI findings in a biopsy-proven case of fibromatosis colli; the signal intensity of the mass on T2-weighted images was slightly less than on gradient-recalled T1-weighted images, consistent with the presence of some fibrous tissue within the muscle mass. The involved portion of the muscle was better defined on MRI than sonography. MRI was helpful in demonstrating the signal characteristics of the mass; localizing the mass to within the sternocleidomastoid muscle; and demonstrating clear surrounding fascial planes with lack of associated lymphadenopathy, airway compression, vascular encasement, bone involvement or intracranial/intraspinal extension associated with other neck masses.

    Objective: To evaluate CT imaging in the diagnosis of child gluteal aggressive fibromatosis. Methods: CT manifestations of child gluteal aggressive fibromatosis were retrospectively analyzed. In total 7 males and 1 female, 2 to 11 years old, were enrolled in study. All cases had been confirmed by surgery and pathology. CT findings were correlatively studied with pathology. Results: Lesions located on the left side were noted in 7 cases, and a lesion located on right side was seen in the rest 1 cam The lesions were elliptical or lobulated on CT images. Three tumors originated from solitary muscle and multiple muscles were involved in other 5 cases. Tumors were well demarcated. Invasion to the adjacent structure was shown in 7 cases. All tumors were homogeneous in density in non-enhanced scan. Compared to the muscles in the same section, 5 tumors were iso -density and 3 tumors were hypo-density. Inside the lesions no hemorrhage, necrosis, cystic degeneration and calcification was revealed. After contrast medium was administrated, iso-dense and homogeneous enhancement as the adjacent muscles was seen in 1 tumor and apparent enhancement were demonstrated in 7 tumors. Seven tumors tended to grow along the longitudinal axis of muscles and infiltrated into fascial space. Atrophy resulting from compression was shown in the adjacent muscles in 6 cases. The major clinical manifestation was limp. Gluteal aggressive fibromatosis was confirmed by pathology in all cases. Conclusion: There are characteristics of child gluteal aggressive fibromatosis in age of onset, gender of the patients, site of the lesion and CT findings as well. CT manifestations were consistent with pathology. CT imaging is helpful in initial diagnosis and differential diagnosis, as well as in assessing the expansion of the tumor and involvement of the adjacent structures. (authors)

    2017-02-01

    Vasculitis of the mesenteric circulation is an uncommon but life-threatening manifestation of systemic vasculitis. Initial symptoms are frequently non-specific and therefore patients often present to primary care physicians and gastroenterologists with abdominal pain or gastrointestinal bleeding. Given the severity of the conditions associated with mesenteric vasculitis, it is imperative to appropriately diagnose and initiate treatment of suspected cases. This review will focus on diseases commonly associated with vasculitis of the mesenteric vessels. Imaging characteristics and clinical features assisting in diagnosis as well as initial approaches to treatment are emphasized. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2014-04-01

    Full Text Available Superior mesenteric vein thrombosis (SMVT is a rare condition, usually caused by infections, intra-abdominal inflammatory diseases, portal hypertension, hypercoagulable states, or contraceptive therapy. Due to its vague symptomatology, SMVT is often diagnosed only after an abdominal contrast-enhanced computed tomography (CT scan. In this article, we present a case of SMVT in a patient with a history of contraceptive drug use and a recent cytomegalovirus infection. A 36-year-old female was admitted to our department with the clinical symptoms of an acute appendicitis. The patient was a smoker and had been using hormonal contraceptives for over a year. Surgery was deemed the best course of action. Before the operation, blood tests showed a mild lymphocytosis and altered liver enzyme levels, while coagulation values were normal. A contrast-enhanced CT scan revealed a complete superior mesenteric vein thrombosis without signs of bowel ischemia. Anticoagulants were immediately administered. A thrombophilia panel did not highlight any noteworthy elements. Cytomegalovirus (CMV tests resulted positive. Since CMV is a rare, but potentially significant cause or precipitating factor for thrombosis in immunocompetent hosts, all patients with an unexplained fever and seemingly spontaneous thrombosis should be screened for CMV infection.

    2014-01-01

    Full Text Available Gingival fibromatosis is characterized by gingival tissue overgrowth of a firm and fibrotic nature. The growth is slow and progressive and is drug-induced, idiopathic, or hereditary in etiology. It occurs isolated or frequently as a component of various syndromes. Our patient presented with the complaint of gingival enlargement associated with progressive deafness, characteristic of Jones syndrome. This case report is important and unique since it is the first known one to have a Jones syndrome-like presentation without a family history. A male patient aged 14 years reported with the chief complaint of swelling of gums and progressive hearing loss in both ears for the past one year. There was no family history or history of drug intake. Enlargement was generalized, fibrotic and bulbous, involving the free and attached gingiva, extending up to the middle 1/3 rd of the crown. Investigations such as pure tone audiogram, impedance audiometry, and Tone decay test concluded that there was severe right and moderate left sensorineural hearing loss. The case was diagnosed to be idiopathic, generalized gingival fibromatosis with progressive hearing loss. The gingival overgrowth was managed by gingivectomy and periodic review. The patient was advised to use high occlusion computer generated hearing aids for his deafness as it was not treatable by medicines or surgery. This unique case report once again emphasizes the heterogeneity of gingival fibromatosis, which can present in an atypical manner.

    2011-01-01

    Full Text Available Desmoid fibromatosis, although histologically benign, infiltrates local structures. The involvement of neural structures can lead to difficult neuropathic pain and the escalating use of analgesics. We report a patient with desmoid fibromatosis of the chest wall causing brachial plexus infiltration. As the tumor was locally invasive and unresectable, he was treated with radiation therapy and oral tamoxifen. On follow-up, there was significant pain relief, sustained reduction in the tumor size, and reduced analgesic requirement. Antineoplastic treatments like local radiation therapy and targeted systemic therapy with hormones or other agents can be considered in the management of selected unresectable desmoid fibromatosis to improve symptom control and reduce polypharmacy.

    Acute mesenteric venous thrombosis signs at MDCT are well described, but the literature lacks studies assessing their evolution. We aimed to describe the radiologic evolution of isolated acute mesenteric venous thrombosis and associated prognostic factors. Patients with isolated acute mesenteric venous thrombosis with follow-up for a minimum of 1 month with MDCT were selected. Images at the acute phase and on follow-up were reviewed in consensus reading. For acute mesenteric venous thrombosis, we searched for low-attenuated intraluminal filling defect. For chronic mesenteric venous thrombosis, we searched for vessel stenosis or occlusion associated with collateral mesenteric veins. Treatment, thrombosis risk factor, symptoms, location, and length and diameter of mesenteric venous thrombosis were reported and correlated with evolution over time. Twenty patients (nine women and 11 men; mean age, 52 years) were selected. Four patients recovered without radiologic sequelae, and 16 developed chronic mesenteric venous thrombosis signs. Anticoagulation did not influence recovery (p = 1). Patients with recovery compared with patients with chronic mesenteric venous thrombosis showed more frequent central lesions (p = 0.03). At diagnosis, the thrombosed segment was shorter and larger in the complete radiologic recovery group compared with the chronic mesenteric venous thrombosis signs group: mean length (± SD) 6.25 ± 3.21 cm and 12.81 ± 5.96 cm, respectively (p = 0.01); mean transverse diameter 1.82 ± 0.42 cm and 1.12 ± 0.34 cm, respectively (p = 0.01). Mesenteric fat infiltration at diagnosis was more frequent in the chronic mesenteric venous thrombosis signs group than in the complete recovery group (p = 0.03). Most cases of acute mesenteric venous thrombosis evolve toward the chronic form with vein stenosis or occlusion and development of collateral veins.

    A case of acute mesenteric ischemia due to thrombosis of superior mesenteric artery and vein in a 44-year-old woman following chemotherapy for invasive laryngeal carcinoma was diagnosed on a multi-detector CT scan. Although the link between malignancy and thromboembolism is widely recognized in patients with cancer, chemotherapy further elevates the risk of thrombosis. Acute mesenteric ischemia associated or not associated with chemotherapy rarely occurs in patients with cancer. Moreover, co-occurrence of superior mesenteric artery and superior mesenteric vein thrombosis is reported for the first time.

    Ascaris lumbricoides is a comman intestinal helminths in humans. It is a parasite which commonly affects society with a low socioeconomic status, especially in tropical and rural areas. Ascaris lumbricoides infestation can lead to serious complications because of the mobility of the worms. The parasite can cause a variety of complications like intestinal obstruction, perforation, biliary obstruction, pancreatitis, peritonitis, liver abscess, cholangiohepatitis, volvulus, and gangrene, etc. A 59-year-old female patient hospitalized with the diagnosis of mesenteric ischemia was operated on for jejunal resection. On the 6th postoperative day, a worm was noticed emerging through the nasogastric tube. Ascaris lumbricoides was determined as a result of the examination microbiology laboratory. The patient was treated successfully with one dose of albendazole 200 mg 1x2. Our case describes a clinical situation of ascariasis observed after jejunal resection and emphasizes the importance of remaining aware of this rare complication of ascariasis.

    Full Text Available A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

    2017-02-01

    Full Text Available A mature teratoma of the pancreas has rarely been reported, and postoperative superior mesenteric artery syndrome (SMAS is extremely rare in pediatric pancreatic surgery. A 12-year-old girl underwent an enucleation of the large mature teratoma located at the pancreas uncus. Although her postoperative recovery was fair, the bile-stained gastric juice continued draining at a rate of>1.5 l per day for 2 weeks. An upper gastrointestinal series revealed an abrupt disruption with to-and-fro peristalsis at the third portion of the duodenum. Endoscopy revealed an extrinsic pulsatile compression of this third portion. The aortomesenteric angle measured 12° on ultrasonography, which met the criteria for SMAS. The patient underwent a modified transposition procedure, “switching jejunojejunostomy,” on postoperative day 18. The gastrointestinal passage gradually improved, and complete oral intake was established 1 month after the first surgery. It was considered that the clinical symptoms of SMAS were caused by an anatomical deformation after the pancreatic tumor resection. Switching jejunojejunostomy was found to be an acceptable therapeutic option for this condition.

    Objective: To determine the diagnostic value of CT in acute mesenteric infarction (AMI). Methods: Ten patients with mesenteric infarction (6 male, 4 female, average age 67.2 years old) were analysed from April 2003 to September 2004, whose symptoms include abdominal pain, melena, nausea and vomiting, etc. Nine cases were confirmed by surgery and pathology except one diedimmediately after CT scan. They included superior mesenteric arterial (SMA) thrombosis (n=4), superior mesenteric venous (SMV) thrombosis (n=5) and inferior mesenteric venous (IMV) thrombosis (n=1). Except one routine CT scan, all the other cases were performed by contrast-enhanced CT examination. Results: The direct sign of acute mesenteric infarction in CT images was filling defect in mesentery vessels (n=8). The indirect signs included dilatation of bowl loops (n=4), bowel wall thickening (n=6), the paper-thin wall sign (n=4), mesenteric stranding (n=5), mesenteric haziness (n=3), pneumatosis of bowel wall (n=2), portal veno gas (n=1) and ascites (n=3). Conclusion: Computed tomography is sensitive to acute mesenteric infarction and is valuable in diagnosis. (authors)

    Thway, Khin; Abou Sherif, Sara; Riddell, Angela M; Mudan, Satvinder

    2016-05-01

    We describe a case of intra-abdominal fibromatosis, which occurred in a 44-year-old woman who had a previous history of gastrointestinal stromal tumor (GIST) of the sigmoid mesocolon, which was treated with imatinib and resection. A mass was detected at the site of ileocolic anastomosis of the previous small bowel resection and sigmoid colectomy, nearly 3 years later. Clinically, this was suspected to represent recurrent GIST and was excised, but histology and mutational analysis showed desmoid-type fibromatosis with a mutation in codon 41 of exon 3 of the CTNNB1 (β-catenin) gene. The occurrence of fibromatosis at the site of excision of GIST is very rare, but its recognition is important as the treatment of the two neoplasms differs significantly. As imaging cannot reliably distinguish between these 2 entities, histological diagnosis is crucial for correct clinical management. © The Author(s) 2015.

    2010-01-01

    Full Text Available Cavitating mesenteric lymph node syndrome (CMLNS is a rare and poorly understood complication of coeliac disease (CD, with only 37 cases reported in the literature. CD is an immune-mediated enteropathy, with alterations seen in the small bowel architecture on exposure to ingested gluten. Those who fail to respond to a strict gluten-free diet are termed to have refractory coeliac disease (RCD. This is associated with serious complications such as enteropathy-associated T-cell lymphoma (EATL. We present the case of a 71-year-old female investigated for weight loss and a palpable intraabdominal mass. Abdominal computed tomographic (CT scan showed multiple necrotic mesenteric lymph nodes. At operation, multiple cavitating mesenteric lymph nodes, containing milky fluid, were found. An incidental EATL was found at the terminal ileum, which was resected. The patient subsequently tested positive for CD. This is the second case report to document an association between CMLNS and EATL. This paper highlights the varied presentation of CD. In this case, the diagnosis of CD was made retrospectively after the complications were dealt with. This paper is followed by a review of relevant literature.

    Full Text Available Omental and mesenteric lipomas are very rare benign lesions of mature adipose tissue. They are well-defined, noninvasive, and encapsulated masses that can be discovered in asymptomatic patients or may cause variable nonspecific symptoms depending on their size and location. The omental and mesenteric lipoma has confusing features in ultrasound; however, computed tomography and magnetic resonance imaging can well characterize and demarcate these lesions. Though few cases of mesenteric and omental lipomas have been reported in the literature, but because of its large size and childhood presentation, the case we present, can be one of the largest childhood omental and mesenteric lipomas ever reported. A 6-year-old girl presented with slowly progressing abdominal distension and repeated dull abdominal pain for last 4 years. Abdominal and pelvic computed tomography examination revealed a huge mesenteric and omental lipoma that was resected surgically without any complications.

    Shklyaev, A E; Malakhova, I G; Bessonov, A G; Utkin, I Yu

    Currently there are several dozens of hereditarily associated thrombophilias and acquired states known to condition the development of a thrombus. Thrombosis of visceral veins appears to be a considerably less often encountered event than thrombosis in the system of visceral arteries. Presented herein in the article is a clinical case report concerning subacute thrombosis of the portal, upper mesenteric and splenic veins, having developed on the background of mutations of 7 genes of the system of haemostasis in a young adult patient. Timely comprehensive examination with determining polymorphism of the haemostasis system genes made it possible to verify the aetiology of the disease in the patient, while multispiral computed tomography contributed favourably to specifying the extension of thrombosis. Due to the developed segmental necrosis of the small intestine the patient was subjected to resection of the necrotised portion of the small intestine followed by establishing an entero-enteric anastomosis. In the postoperative period adequate anticoagulant therapy was adjusted in order to prevent relapse of thrombogenesis.

    2011-01-01

    Full Text Available Thrombophilia is a rare but potentially catastrophic phenomenon occurring in patients having tendency of thrombosis. It may lead to serious complications. The etiology of thrombophilia is thought to be multifactorial and related to both acquired and inherited factors. Inflammatory bowel disease is an acquired cause of thrombophilia. Thromboembolic events are seen during inflammatory bowel disease, especially during the active period of the disease. In inflammatory bowel disease, thrombus formation in portal, splenic and mesenteric veins are not common. Besides, the association of genetic disorders related to metabolism of homocysteine with inflammatory bowel disease has been evidenced, especially in Crohn disease and rarely in ulcerative colitis. We present a rare case of ulcerative colitis in association with combined portal, splenic and mesenteric vein thrombosis. The patient was recently diagnosed with the disease which was in the inactive period. Interestingly, our patient was also heterozygous for the mutation in methylenetetrahydrofolate reductase (MTHFR gene.

This report describes a man with alcoholic liver cirrhosis, who died of massive hematochezia due to SMVT. A medicolegal autopsy disclosed a thrombus at the superior mesenteric vein and hemorrhagic infarction of the bowel wall, an area also within the territory of the superior mesenteric vein. Liver cirrhosis, an enlarged spleen, and esophageal varices without rupture were also observed, but ulcers and variceal bleeding were not. Other organs showed no significant findings. His blood alcohol level was 0.14% w/v. Thus, this man died from severe hematochezia associated with SMVT due to liver cirrhosis and alcohol dehydration, which can lead to coagulopathy and rapid progress of thrombus formation. This is the first report on an alternate cause for massive gastrointestinal hemorrhage with a cirrhotic patient in a forensic autopsy. © 2015 American Academy of Forensic Sciences.

    Full Text Available Abstract Background Fibromatosis-like metaplastic carcinoma is a newly described metaplastic breast tumor, literature on which is still evolving. Case presentation A 77-year-old lady presented with a 2 × 2 cm mass with irregular margins in the upper and outer quadrant of left breast. Fine needle aspiration cytology (FNAC from the lump was inconclusive. A lumpectomy was performed and sent for frozen section, which revealed presence of spindle cells showing mild atypia in a sclerotic stroma. The tumor cells revealed prominent infiltration into the adjacent fat. A differential diagnosis of a low-grade sarcoma vs. a metaplastic carcinoma, favoring the former, was offered. Final histology sections revealed an infiltrating tumor with predominant spindle cells in a collagenous background, simulating a fibromatosis. Adjacent to the tumor were foci of benign ductal hyperplasia and a micropapilloma. Immunohistochemistry (IHC showed diffuse co-expression of epithelial markers i.e. cytokeratins (CK, HMWCK, CK7 and EMA along with a mesenchymal marker i.e. vimentin in the tumor cells. Myoepithelial markers (SMA and p63 showed focal positivity. A diagnosis of a low-grade fibromatosis-like carcinoma breast associated with a micropapilloma was formed. Conclusion Fibromatosis-like carcinoma is a rare form of a metaplastic breast tumor. This diagnosis requires an index of suspicion while dealing with spindle cell breast tumors. The importance of making this diagnosis to facilitate an intra operative surgical planning is marred by diagnostic difficulties. In such cases, IHC is imperative in forming an objective diagnosis.

    The authors report the case of a 35 year old woman dead of cachexia in the course of a refractory adult coeliac disease. The autopsy revealed multiple lymphadenopathies exclusively found in the small intestinal mesentery; all these lymph nodes were destroyed by an extensive haemorrhagic necrosis. There was neither lymphoma nor cavitation. These original findings are interpreted as the consequence of a localized intravascular coagulation, and probably a step towards cavitation or atrophy.

    Gingival enlargement is common among patients and can be caused by a variety of etiological factors. The most common reason is poor oral hygiene and high bacterial load that leads to gingival inflammation and enlargement. Other implicated factors include systemic drugs, such as Phenytoin (Dilantin) taken by epileptic patients, Calcium Channel Blockers such as Nifedipine (Procardia) and Verapamil (Calan) for the treatment of hypertension, arrhythmia and angina. Another class of medication associated with gingival enlargement is immunosuppressive agents given to organ-transplant patients to prevent rejection of the new element, such as Cyclosporine. Some enlargements could be associated with other conditions such as puberty, pregnancy or diabetes or be a symptom of a systemic disease (leukemia, Wegener's granulomatosis or sarcoidosis). In rare cases the cause for the enlargement is genetic and termed Hereditary Gingival Fibromatosis (HGF). HGF is a genetic disorder characterized by a progressive enlargement of the gingiva. Histologically, the gingiva is characterized by an accumulation of dense fibrous connective tissue. This is believed to be due to an imbalance between synthesis and degradation of extracellular matrix composed mainly of collagen molecules or due to an alteration in fibroblast proliferation. Different pathogenic mechanisms have been proposed and examined over the years but no precise process has been identified. The main objective of this paper is to discuss this genetic anomaly and support it with clinical cases of a mother and her two children. It will focus on the clinical and histologic characteristics of HGF as well as known biologic and genetic features and treatment modalities.

    Pancreatitis, panniculitis and polyarthritis syndrome is a very rare extra-pancreatic complication of pancreatic diseases. While in most cases this syndrome is caused by acute or chronic pancreatitis, we report a case of a 62-year-old man presenting with extensive intraosseous fat necrosis, polyarthritis and panniculitis caused by a post-pancreatitis pseudocyst with a fistula to the superior mesenteric vein and extremely high blood levels of lipase. This became symptomatic 2.5 years after an episode of acute pancreatitis and as in most cases abdominal symptoms were absent. Treatment by surgical resection of the pancreatic head with the pseudocyst and mesenteric fistula led to complete remission of all symptoms. A review of the literature revealed that all publications are limited to case reports. Most authors hypothesize that an unspecific damage can cause a secretion of pancreatic enzymes to the bloodstream leading to a systemic lipolysis and fat tissue necrosis, especially of subcutaneous tissue, bone marrow, inducing panniculitis, polyarthritis and osteonecrosis. Even if caused by an acute pancreatitis abdominal symptoms are often mild or absent in most cases leading to misdiagnosis and poor prognosis. While symptomatic treatment with NSAR and cortisone showed poor to moderate response, causal treatment can be successful depending on the underlying pancreatic disease. Copyright © 2017.

    Mesenteric lipoma is a rare benign neoplastic condition that can grow to be very large and mimic other midgut fatty tumors. These benign tumors can cause various gastrointestinal symptoms such as obstruction and abdominal pain. We report the case of a 9-year-old boy who presented with a small bowel obstruction caused by torsion of a large mesenteric lipoma. This is an important but unusual tumor and should be considered in the differential of fatty lesions within the mesentery. (orig.)

    Superior mesenteric artery syndrome (SMAS) is the obstruction of the duodenum in the third portion due to this artery. We present a case of chronic oral feeding intolerance due to this problem. A 24 year-old woman, with a time of evolution of 1 year and a half of postprandial epigastric pain with nausea, vomiting, and loss of 30 kg managed as acid-peptic disease. The patient was studied with gastrointestinal contrast study and endoscopy without conclusive results. The patient was admitted for unstoppable vomiting, malnutrition, and severe dehydration. A laparotomy was performed and SMAS was identified. We performed Treitz's ligament section and gastrojejunoanastomosis. Her clinical outcome was satisfactory and the patient was discharged without complications. SMAS is also called Wilkie's syndrome. SMAS is more frequent in women between the 10 and 39 years. The disease due to the decrease of the angle between the superior mesenteric artery and the aorta, to the anomalous origin of this artery, or to the shortening of Treitz's ligament. SMAS may appear as a sudden weight loss. Food intolerance is a predominant symptom. Diagnosis can be made with x-ray studies. Treatment is medical or surgical, with Treitz's ligament section, duodenojejunoanastomosis, and in some cases gastrojejunoanastomosis. SMAS should be considered as no the differential diagnosis of chronic oral feeding intolerance.

    Full Text Available Superior mesenteric artery syndrome is a rare and lifethreateningclinical condition caused by the compressionof the third portion of the duodenum between the aortaand the superior mesenteric artery’s proximal part. Thiscompression may lead to chronic intermittent, acute totalor partial obstruction. Sudden weight-loss and the relateddecrease in the fat tissue are considered to be the etiologicalreason of acute stenosis. Weight-loss accompaniedby nausea, vomiting, anorexia, epigastric pain, andbloating are the leading complaints. Barium radiographs,computerized tomography, conventional angiography,tomographic and magnetic resonance angiography areused in the diagnosis. There are medical and surgical approachesto treatment.

    To describe a case of superior mesenteric vein thrombosis associated with IVF. Case report. University teaching hospital. A 33-year-old female developed progressive abdominal pain several days after ET in her first IVF cycle. A computed tomography scan 12 days after ET showed a superior mesenteric vein thrombosis. Therapeutic anticoagulation. Resolution of the superior mesenteric vein thrombosis with therapeutic anticoagulation. Early diagnosis and treatment of a superior mesenteric vein thrombosis associated with IVF led to a favorable outcome. Endocrine alterations consequent to controlled ovarian hyperstimulation for IVF place patients at risk for thromboembolic events. Thromboembolic events may occur during an IVF cycle in the absence of overt ovarian hyperstimulation, an inherited thrombophilia, or pregnancy. Early diagnosis and treatment of superior mesenteric vein thrombosis can lead to a favorable outcome. Treatment guidelines for superior mesenteric vein thrombosis in setting of IVF are discussed.

    To investigate the clinical manifestations and mortality related risk factors in patients with acute superior mesenteric artery embolism (ASMAE). Clinical data of forty-three confirmed ASMAE patients in the PLA General Hospital from June 2002 to June 2012 were retrospectively analyzed. All patients were classified into the survival group (28 cases) and the death group (15 cases) according to the prognosis. The prognosis associated factors were further analyzed. The study group consisted of 31 men (72.1%) and 12 women (27.9%), with average age of (63 ± 11) years. The majority patients with ASMAE in our study had history of atherosclerotic diseases. The main clinical manifestations included abdominal pain [100% (43/43)], nausea and vomitting [55.8% (24/43)], hematochezia [32.6% (14/43)]. Abdominal CT scan was performed in 74.4% (32/43) patients with a high positive result of 96.9% (31/32).Weight loss occurred more frequently in survival group than in death group [32.1% (9/28) vs 6.7% (1/15) , P = 0.001]. Moreover, weight loss has been shown as a protective factor for ASMAE survival (OR = 0.75, P = 0.038) by logistic analysis. Compared with the death group, the incidence of either peritoneal irritation sign or ascites was significantly lower in survival group [respectively 7.1% (2/28) vs 66.7% (10/15), 14.3% (4/28) vs 73.3% (11/15), P < 0.05], which were two independent risk factors of mortality (OR = 8.51, P = 0.014; OR = 3.07, P = 0.028) . The incidence of main artery embolism of superior mesentery artery (SMA) in death group was higher than that in survival group [93.3% (14/15) vs 60.7% (17/28), P = 0.023]. Main artery embolism of SMA was also an independent mortality risk factor of ASMAE patients (OR = 5.05, P = 0.039) . A total of 18 patients were treated with enterectomy.Intestine excision length was shorter in survival group than in death group [(82.8 ± 25.2)cm vs (141.0 ± 18.1) cm, P = 0.017]. The time from onset to operation in survival group was shorter

    Mesenteric cysts (MC) are benign cystic tumors that grow within mesentery or omentum tissue. We have reviewed the cases of MC reported and operated on in our centre. Retrospective review of clinical records of MC cases during the period 2002-2012 RESULTS: A total of 7 patients were found. Mean age was 5.3 years (range 3-11). Abdominal ultrasound was the diagnostic tool in all cases, except for one, which was diagnosed during laparotomy. All presented abdominal pain, 5 (71.4%) vomiting, 4 (57%) gross abdominal distension, 3 (42.8%) fever, and none presented complete abdominal obstruction, although 2 patients (28.6%) had slight sub-occlusion symptoms. All MC were pedicled or sesil, except for our last case, which extended into the retroperitoneum. All specimens were reported as Limphatic Malformation. None recurred. MC in children are mostly Lymphatic Malformations of mesentery or omentum origin, and clinical presentation varies from chronic abdominal pain to sudden-onset peritonitis or volvulus. About 50-60% require intestinal resection and anastomosis. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Mesenteric lymphangiography and thoracic duct ligation were performedon 19 cats with chylothorax between 1987 to 1992. Chylothorax was diagnosed on the basis of detection of chylomicrons in the pleural effusion or determination of a cholesterol concentration:triglyceride concentration ratio of 12 months after surgery. Four cats died between 2 and 13 days after thoracic duct ligation, but pleural effusion had resolved in 3 of these 4 cats at the time of death. Five cats were euthanatized 8 to 36 days after surgery because of persistent chylous effusion after thoracic duct ligation

    Brucellosis is a multisystem infection found worldwide that has a broad range of characteristics, which range from acute fever and hepatomegaly to chronic infections that most commonly affect the central nervous system, cardiovascular system, or skeletal system. Gastrointestinal and splanchnic artery involvements in brucellosis are relatively uncommon. We report a case of brucellosis in an adolescent presenting as intermittent abdominal pain, diarrhea, and fever, with intestinal tract involvement. And stenosis of the celiac artery and the superior mesenteric artery was found after exposed to risk factors of Brucella infection. Splanchnic vessels stenosis and an endothelial lesion may exacerbate the prevalent symptom of abdominal pain, as a form of colic pain, occurring after eating. The patient was diagnosed as brucellosis. The narrowing of the SMA and CA was suspected to be vasculitis secondary to the brucellosis. The patient was treated with minocycline and rifampicin for 12 weeks totally. The gastrointestinal manifestations of brucellosis recovered rapidly under intensive treatment. However, follow-up imaging revealed that the superior mesenteric artery and celiac artery stenosis was unimproved. In brucellosis, gastrointestinal manifestations may be the only observable features of the disease. Splanchnic arterial stenosis is a rare complication of brucellosis. Sonography and computed tomography may be useful for both diagnosis and follow-up.

    Directory of Open Access Journals (Sweden)

    Christian Ovalle-Chao

    2017-04-01

    Full Text Available Superior mesenteric artery (SMA syndrome is a rare condition caused by compression of the third portion of duodenum by the angle between the superior mesenteric artery against the aorta. A rare presentation of SMA syndrome is following scoliosis repair and spinal fusion with a low incidence and most of these patients present with symptoms within one to two weeks or even more after the surgical repair. A high suspicion index after surgical correction of scoliosis with well-known risk factors (low BMI, low percentile of weight for height, and a high degree of change in the Cobb's angles can anticipate the postoperative diagnosis. Management has been described for postsurgical scoliosis repair with a late onset presentation of SMA syndrome with nutritional support with good success rates, but there is no data for best treatment management for acute onset especially when the surgical correction of the spine causes complete duodenal obstruction and a surgical intervention might be warranted. Here in, we present a 14 year-old boy with an acute 24-h postoperative SMA syndrome following surgical correction of scoliosis.

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

    The article deals with the problems related to acute impairment of mesenteric blood circulation, known as a nosological entity associated with an extremely high mortality rate. The authors point out that there are currently no common approaches to appropriate management of the pathology concerned and define the role of modern minimally invasive methods, which roentgenosurgical interventions belong to, making it possible to rapidly, safely and efficiently cope with the problem of thrombosis of mesenteric vessels, as well as to decrease lethality and improve the prognosis in this cohort of patients. Also presented herein is a detailed description of a clinical case report regarding successful endovascular treatment of a patient suffering from acute thrombosis of the superior mesenteric artery. This is followed by assessing efficacy and safety of the method employed, and, finally, suggesting tactical solutions in treatment of patients presenting with acute pathology of mesenteric vessels.

  16. Can the MRI signal of aggressive fibromatosis be used to predict its behavior?

    2009-01-01

    Purpose: Aggressive fibromatosis is an invasive non-metastasizing soft-tissue tumor. Until recently, the standard treatment combined surgery and radiation therapy, but new studies reported that conservative strategies with or without medical treatment could be the best management. The aim of this study was to analyze and correlate the size and MR imaging signal features of aggressive fibromatosis with its behavior in order to choose the best treatment. Materials and methods: Between March 1985 and December 2005, 27 patients with at least 2 consecutive MRI examinations and no surgery or radiation therapy in between were recorded. There were 9 men and 18 women, and median age was 31 years. They underwent 107 MRI examinations of 47 lesions, 29 of which were medically treated, while the remaining 18 did not receive any drug administration. The size and signal changes of each lesion were studied over time on T2- and/or T1-weighted sequences after injection of contrast medium. RECIST criteria were used for size: only a 30% decrease or a 20% increase in the size of the main dimension was considered significant. We classified the appearance of the signal into six categories in order of increasing intensity and then we established the related variations over time. Results: The size of 79% of the lesions in the treated group and 82% in the untreated group remained stable. The initial signal of stable lesions or those exhibiting an increase in size was most frequently high. There was a high rate of signal stability over time, whatever the initial signal and size changes. Changes in size were not correlated with the initial MR signal. A decrease in size associated with a decreased signal was observed in three cases exclusively in the treated group. Conclusion: Fibromatoses are a group of soft-tissue tumors with variable characteristics on MRI, but it is not possible to predict their behavior based on the MRI signal

  17. Successful Treatment of Acute on Chronic Mesenteric Ischaemia by Common Iliac to Inferior Mesenteric Artery Bypass

    Directory of Open Access Journals (Sweden)

    D. N. Coakley

    2015-01-01

    Full Text Available Chronic mesenteric ischaemia is a rare and potentially fatal condition most commonly due to atherosclerotic stenosis or occlusion of two or more mesenteric arteries. Multivessel revascularisation of both primary mesenteric vessels, the celiac artery and superior mesenteric artery (SMA, is the current mainstay of treatment; however, in a certain cohort of patients, revascularisation one or both vessels may not be possible. Arteries may be technically unreconstructable or the patient may be surgically unfit for the prolonged aortic cross clamping times required. Here we present a case involving a 72-year-old woman with acute on chronic mesenteric ischaemia. She was a high risk surgical patient with severe unreconstructable stenotic disease of the SMA and celiac arteries. She was successfully treated with single vessel revascularisation of the inferior mesenteric artery (IMA via a common iliac to IMA reversed vein bypass. At two-year follow-up, the graft remains patent and the patient continues to be symptom-free and is maintaining her weight.

    Acute mesenteric ischemia is still fatal in 50% to 70% of cases. This consensus paper was written with the participation of physicians from all of the involved specialties for the purpose of improving outcomes. Mesenteric ischemia must be recognized as a vascular emergency requiring rapid and efficient clinical evaluation and treatment. We reviewed pertinent literature that was retrieved by a PubMed search on the terms "mesenteric ischemia" AND "arterial" OR "venous" OR "clinical presentation" OR "diagnosis" OR "therapy" OR "surgery" OR " interventional radiology." Our review also took account of the existing guidelines of the American College of Cardiology/American Heart Association. Intensive discussions among the participating physicians, representing all of the specialties involved in the management of mesenteric ischemia, led to the creation of this interdisciplinary paper. Biphasic contrast-enhanced computerized tomography is the diagnostic tool of choice for the detection of arterial or venous occlusion. If non-occlusive mesenteric ischemia is suspected, angiography should be performed, with the option of intraarterial pharmacotherapy to induce local vasodilation. Endovascular techniques have become increasingly important in the treatment of arterial occlusion. Embolic central mesenteric artery occlusion requires surgical treatment; surgery is also needed in case of peritonitis. Portal-vein thrombosis can be treated by local thrombolysis through a transhepatically placed catheter. This should be done within 3 to 4 weeks of the event to prevent later complications of portal hypertension. Rapid diagnosis (within 4 to 6 hours of symptom onset) and interdisciplinary cooperation in the provision of treatment are required if the poor outcome of this condition is to be improved.

    Non-occlusive mesenteric ischemia (NOMI) compromises all forms of mesenteric ischemia with patent mesenteric arteries. It generally affects patients over 50 years of age suffering from myocardial infarction, congestive heart failure, aortic insufficiency, renal or hepatic disease and patients following cardiac surgery. Non-occlusive disease accounts for 20-30% of all cases of acute mesenteric ischemia with a mortality rate of the order of 50%. Acute abdominal pain may be the only early presenting symptom of mesenteric ischemia. Non-invasive imaging modalities, such as CT, MRI, and ultrasound, are able to evaluate the aorta and the origins of splanchnic arteries. Despite the technical evolution of those methods, selective angiography of mesenteric arteries is still the gold standard in diagnosing peripheral splanchnic vessel disease. In early non-occlusive mesenteric ischemia, as opposed to occlusive disease, there is no surgical therapy. It is known that mesenteric vasospasm persists even after correction of the precipitating event. Vasospasm frequently responds to direct intra-arterial vasodilator therapy, which is the only treatment that has been shown to be effective. (orig.)

    We report a case of superior mesenteric artery thrombosis after the abrupt discontinuation of rivaroxaban in a 59-year-old male patient. The initial presentation was of sudden onset abdominal pain, nausea, vomiting, diarrhea, and hematochezia in the setting of recently holding rivaroxaban anticoagulation for an atrial flutter ablative procedure. Imaging revealed thrombosis of the superior mesenteric artery and acute mesenteric ischemia requiring emergent surgical intervention for embolectomy. Upon exploratory laparotomy, the bowel was found to be viable, and an embolectomy with patch angioplasty was successful without complication. This case illustrates the need for emergency medicine clinician familiarity with this possible medication adverse event with rivaroxaban.

    Mesenteric venous thrombosis is a rare disorder with a high mortality rate. Since patients remain asymptomatic, diagnosis of the disease is difficult. Diagnosis can be mainly made with either laparotomy or autopsy. Many factors are considered in the etiology of mesenteric venous thrombosis. Liver cirrhosis and chronic pyelonephritis, which we detected in the autopsy and histologic examination of our case, are considered as two of the factors. In our study, it was aimed to present a case with near-total intestinal necrosis caused by portal vein thrombosis which spread to the lineal vein, pancreatic vein and to the branches of superior mesenteric veins.

    Chronic mesenteric ischemia (CMI) is a rare disorder that is commonly caused by progressive atherosclerotic stenosis or occlusion of one or more mesenteric arteries. Endovascular treatment for symptomatic CMI represents a viable option, especially in high-operative risk patients. We report a case of acute symptomatic CMI with chronic totally occlusion of the superior mesenteric artery (SMA) associated with significant stenosis of celiac trunk (CT) and inferior mesenteric artery (IMA) that underwent endovascular treatment of all the three mesenteric arteries: stenting of CT and IMA stenosis, and recanalization of the SMA occlusion by retrograde crossing via the Villemin arcade.

    Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with few therapeutic options. At present, surgical resection remains the only potential curative treatment for PDAC. However, only 15-20% of patients with PDAC are eligible for lesion resection. Total pancreatectomy (TP) and superior mesenteric-portal vein resection (SMPVR) may increase the rate of resection of PDCA, but the effect of this approach on improving long-term patient outcomes remains controversial. The present study investigated a case of PDAC in the pancreatic neck of a male patient. The patient underwent a TP, combined with SMPVR, for a margin-negative resection. Following an uneventful post-operative recovery, the patient received adjuvant chemoradiotherapy. The patient is currently alive at six years post-surgery, with a high quality of life. Given the clinical outcome of this patient, TP combined with SMPVR may provide PDAC patients with an opportunity for long-term survival. Therefore, patients with PDAC that is believed to be unresectable based on pre-operative assessment, may benefit from TP and SMPVR.

  8. Managing mesenteric vasculitis.

    2015-03-01

    Mesenteric vasculitis is a rare diagnosis, but it comprises a group of disorders that may have devastating manifestations. It is often difficult to diagnose using clinical symptoms and biomarkers. Vascular imaging often provides the best opportunity for the noninvasive diagnosis of vasculitis and obviates the need for performing a biopsy. The medical management of vasculitis involves controlling the inflammatory process with the use of steroids or other immunosuppressants, but medical therapy does not consistently provide regression of the vascular changes (ie, aneurysms or vascular occlusions) seen at the time of the initial diagnosis. Operative management remains the mainstay of therapy for focal occlusive or aneurysms, but the treatment options for multifocal disease remain challenging. Endovascular treatment is increasingly being used as a first line of treatment for symptomatic vasculitis. Interventionalists should be familiar with the indications and outcomes associated with the various therapeutic options for mesenteric vasculitis-associated occlusive disease and aneurysms.

    2010-01-01

    Purpose: We analyzed our experience with intraoperative electron radiotherapy (IOERT) followed by moderate doses of external beam radiotherapy (EBRT) after organ-sparing surgery in patients with primary or recurrent aggressive fibromatosis. Methods and Materials: Indication for IOERT and postoperative EBRT as an individual treatment approach to avoid mutilating surgical procedures was seen when complete surgical removal seemed to be unlikely or impossible. A total of 31 lesions in 30 patients were treated by surgery and IOERT with a median dose of 12 Gy. Median age was 31 years (range, 13-59 years). Resection status was close margin in six lesions, microscopically positive in 13, and macroscopically positive in 12. Median tumor size was 9 cm. In all, 25 patients received additional EBRT, with a median dose of 45 Gy (range, 36-54 Gy). Results: After a median follow-up of 32 months (range, 3-139 months), no disease-related deaths occurred. A total of five local recurrences were seen, resulting in actuarial 3-year local control rates of 82% overall and 91% inside the IOERT areas. Trends to improved local control were seen for older age (>31 years) and negative margins, but none of these factors reached significance. Perioperative complications were found in six patients, in particular as wound healing disturbances in five patients and venous thrombosis in one patient. Late toxicity was seen in five patients. Conclusion: Introduction of IOERT into a multimodal treatment approach in patients with aggressive fibromatosis is feasible with low toxicity and yielded good local control rates even in patients with microscopical or gross residual disease.

    Byard, Roger W

    2012-05-01

    Acute mesenteric ischaemia is a vascular emergency that arises when blood flow to the intestine is compromised leading to tissue necrosis. It is primarily a condition of the elderly associated with significant morbidity and mortality. Causes include arterial thromboembolism, venous thrombosis and splanchnic vasoconstriction (so-called nonocclusive mesenteric ischaemia). Reperfusion injury and breakdown of the intestinal mucosal barrier lead to metabolic derangements, sepsis and death from multiorgan failure. The diagnosis may be difficult to make clinically and numbers of cases are increasing due to ageing of the population. The clinical and pathological features are reviewed with discussion of predisposing conditions. Careful dissection of the mesenteric vasculature is required at autopsy with appropriate histologic sampling and documentation of associated comorbidities. Other organs need to be checked for thrombi and the possibility of testing for inherited thombophilias should be considered. Toxicological evaluation, particularly in younger individuals, may reveal evidence of cocaine use. On occasion no obstructive lesions will be demonstrated, however the confounding effects of post-mortem autolytic and putrefactive changes may mean that nonocclusive mesenteric ischaemia may be difficult to diagnose.

    Acute mesenteric ischemia is secondary to acute embolic disease or thrombosis of the superior mesenteric artery. Further pathologies that manifest themselves with the same clinical presentation are thrombosis of the superior mesenteric vein and non-occlusive disease. The patients are admitted to the emergency room with an acute abdomen. Most patients are more than 70 years old. Known risk factors for mesenteric ischemia are cardiac diseases as atrial fibrillation, aneurysms of the aorta and the visceral arteries, occlusive arterial diseases, tumorigenic compression of the vessel and several diseases that result in a reduction of the flow and intravascular volume in the superior mesenteric artery. The golden standard in the diagnosis of acute mesenteric ischemia is CT-angiography of the abdominal vessels with 3 D reconstruction. The therapy is different and dependent from the underlying pathology. A statistically significantly elevated mortality of more than 95% is associated with a delay of surgical or interventional therapy of more than 12 hours after the initial symptoms and non-occlusive mesenteric ischemia. Because of the advanced age of the patients and the co-morbidities a non-surgical interventional re-canalisation of the superior mesenteric vessels is recommended. A laparotomy is necessary in all patients with peritonitis and/or bowel necrosis or perforation. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available AIM The aim of the study was to evaluate efficacy, sensitivity, specificity of ultrasonography, conventional angiography, CT Angiography in mesenteric ischaemia. MATERIALS AND METHODS Prospective study was performed. 35 patients with clinically suspected mesenteric ischaemia were included in the study. The study was conducted from month of November 2013 to August 2015. The patients age ranged from 35 to 70 years (Mean age was 57±11.2 years. All cases met the criteria of acute nontraumatic or chronic abdominal pain and suspected mesenteric vascular ischaemia. All 35 cases were evaluated in surgery department, then underwent USG, conventional angiography, CTA. Out of 20 patients, 2 patients were inconclusive and 4 patients had other findings of abdominal pain. USG and CT angiographic findings were correlated with surgical findings in acute mesenteric ischaemia (AMI cases & conventional angiography in chronic mesenteric ischaemia (CMI cases. RESULT Ultrasonography has lower sensitivity and high specificity. Conventional angiography has moderate sensitivity and high specificity. CT angiography is highly sensitive and specific in detecting mesenteric ischaemia. CONCLUSION Conventional angiography is considered as the gold standard test for patients with acute and chronic mesenteric ischaemia except for hemodynamically unstable patients with acute mesenteric ischaemia. CTA is an emerging diagnostic test with high sensitivity and specificity in the setting of both acute and chronic mesenteric ischaemia and should be considered the first-line imaging test. CT can also accurately assess for other causes of acute and chronic abdominal pain, and it provides excellent anatomic mapping of the mesenteric vasculature, which is essential in the preoperative planning. US of the abdomen with Doppler waveform analysis can depict proximal mesenteric thrombosis and secondary signs of bowel compromise, but it is limited in the diagnosis of distal occlusions

    Ascaris lumbricoides or round worm infestation is quite common in the developing world. It affects all age groups but is more common in children. Most of the cases remain asymptomatic. The usual presentation is an intestinal obstruction. The physicians should be aware of this condition and consider it in the differential diagnosis when faced with such a case. The rare fatal complications include bleeding, perforation and gangrene.

    Fifty-six patients, selected by clinical criteria, underwent angiography for suspected acute mesenteric ischemia. Twenty-nine patients subsequently did not have mesenteric ischemia and had negative arteriograms. Twenty-seven patients had mesenteric ischemia: arterial thrombosis (three), arterial embolus (seven), venous thrombosis (five), vasculitis with thrombosis (one), and nonocclusive ischemia (11). Of these 27 patients, 12 (44%) received intraarterial vasodilator infusions. Overall, 13 (48%) of the 27 patients survived their hospitalization, including five (45%) of 11 with nonocclusive ischemia. This experience confirms that nonocclusive ischemia is the most common form of the disorder diagnosed by angiography. Most patients with mesenteric ischemia are candidates for intraarterial vasodilator therapy. Early angiography in patients with suspected acute mesenteric ischemia permits early diagnosis and differentiation between occlusive and nonocclusive types. Interventional infusion therapy may improve survival

    Imaging criteria for measuring the response of desmoid fibromatosis to systemic therapy are not well established. We evaluated a series of patients with desmoids who underwent systemic therapy to document magnetic resonance imaging (MRI) features associated with a positive clinical response. This Institutional Review Board-approved retrospective study included 23 patients (mean age 40.5) with 29 extra-abdominal tumors. Therapeutic regimens included cytotoxic chemotherapy (n = 19), targeted therapy (n = 3), and nonsteroid anti-inflammatory drugs (NSAIDS; n = 1). Clinical effects were categorized as progressive disease, stable, or partial response. Maximum tumor dimension (D{sub max}), approximate tumor volume (V{sub Tumor}), and quantitative tumor T2 hyperintensity and contrast enhancement (relative to muscle) for pre- and post-treatment MRIs were compared. Three lesions progressed, 5 lesions were stable, whereas 21 showed a clinical response. D{sub max} decreased more in responders (mean -11.0 %) than in stable/progressive lesions (mean -3.6 and 0 % respectively, p = 0.28, ANOVA); by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) 27 out of 29 lesions were ''stable,'' including the 3 progressive lesions. In responders, V{sub Tumor} change averaged -29.4 %, but -19.2 % and +32.5 % in stable and progressive lesions respectively (p = 0.002, ANOVA); by 3D criteria 14 out of 29 lesions showed a partial response. T2 hyperintensity decreased by 50-54 % in partial response/stable disease, but only by 10 % in progressive lesions (p = 0.049, t test). Changes in contrast enhancement ranged from -23 % to 0 %, but were not statistically significant among response groups (p = 0.37). Change in T2 hyperintensity showed a positive correlation with volumetric change (r = 0.40). Decreases in volume and T2 hyperintensity reflect the positive response of desmoid fibromatosis to systemic therapy; RECIST 1.1 criteria are not sensitive to clinically

  19. Heterotopic Mesenteric Ossification After Total Colectomy for Bleeding Diverticulosis of the Colon—A Rare Case Report

    Directory of Open Access Journals (Sweden)

    Huang-Jen Lai

    2007-01-01

    Full Text Available Heterotopic bone formation within an abdominal incision is a rare sequela of abdominal surgery. Only a few previous reports have noted heterotopic ossification in the mesentery of the small intestine and periileostomy. Here, we report the case of a 60-year-old man who underwent emergent laparotomy and total colectomy with end ileostomy and developed this condition 1 month postoperatively. Heterotopic ossification in the peri-ileostomy tissue caused stenosis of the ileostoma. Laparotomy for re-anastomosis due to a large bone formation at an abdominal midline scar is very difficult and results in a massive abdominal wall defect. Therefore, we used a lower transverse incision to avoid the site of bone formation and resected the terminal ileum with its ossified mesentery. Then, we successfully carried out an anastomosis between the ileum and the rectum. The possible pathogenesis is a metaplastic mechanism of differentiation of immature multipotent mesechymal cells. Our case provides the experience of treatment and new perspective on currently held hypotheses of heterotopic bone formation. [J Formos Med Assoc 2007;106(2 Suppl:S32-S36

    This is a report about 4 patients with aneurysms of the superior mesenteric artery of arteriosclerotic, mycotic and probably congenital etiology together with a review of the literature as to the etiology, diagnostic possibilities and therapy. Arteriography is the method of choice even though a diagnosis may be possible by sonography or CT in special cases. Even though an aneurysm of the superior mesenteric artery is rare, it has to be considered in the differential diagnosis of persisting abdominal problems of unknown origin. This is especially true for patients with a predisposing history such as previous or existing endocarditis, sepsis, arteriosclerosis and hypertension. Because of the possibility of rupture followed by life threating bleeding an adequate diagnostic step such as arteriography has to be considered finally. (orig.) [de

  3. Mesenteric Air Embolism Following Enteroscopic Small Bowel Tattooing Procedure

    2012-01-01

    Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

    Mesenteric vein thrombosis occurs rarely and is responsible for approximately 5-15% of all cases of acute mesenteric ischemia. The aim of this report was to discuss the management of mesenteric vein thrombosis based on our experience with 34 patients. In the present study, 34 patients who were admitted to our emergency surgery department between January 2007 and January 2010 with a diagnosis of acute mesenteric vein thrombosis were assessed retrospectively. Patients with peritoneal signs first underwent diagnostic laparoscopy to rule out perforation or bowel gangrene. We performed a second-look laparoscopy within 72 hours of the first operation. All patients were administered 100 mg/kg of the anticoagulant enoxaparin twice daily. In the 6th and 12th months of follow up, CT angiography was performed to evaluate recanalization of the veins. CT angiography revealed superior mesenteric vein thrombosis in 25 (73%) patients, portal vein thrombosis in 24 (70%) patients, and splenic vein thrombosis in 12 (35%) patients. Eleven patients with peritoneal signs underwent diagnostic laparoscopy; eight of the patients underwent small bowel resection, anastomosis, and trocar insertion. During second-look laparoscopy, small bowel ischemia was found in two patients and re-resection was performed. Early diagnosis with CT angiography, surgical and non-surgical blood flow restoration, proper anticoagulation, and supportive intensive care are the cornerstones of successful treatment of mesenteric vein thrombosis.

    Acute pancreatitis can result in many vascular complications in both artery and vein. Venous complication usually occurs as a form of splenic or portal vein thrombosis, and also can simultaneously occur in superior mesenteric vein as well. Rarely, isolated superior mesenteric vein thrombosis occurs as a venous complication. Although it is uncommon, mesenteric vein thrombosis is an important clinical entity because of the possibility of mesenteric ischemia and infarction of small bowel. The treatments of mesenteric venous thrombosis include anticoagulation therapy, transcatheter therapy and surgical intervention. We report a case of 45-year- old man who had acute pancreatitis with isolated superior mesenteric vein thrombosis, which was spontaneously dissolved with the resolution of underlying inflammation without anticoagulation or surgical intervention.

  6. Acute thrombosis of a mesenteric artery drug-eluting stent following clopidogrel cessation.

    Sutphin, Daniel; Stevens, Scott; Kirzeder, Daniel; Gash, Judson

    To describe thrombosis of sirolimus-coated mesenteric arterial stents following cessation of clopidogrel therapy. Cardiac drug-eluting stent thrombosis following cessation of antiplatelet therapy with clopidogrel has been associated with increased mortality. The application of such stents in the mesenteric arterial system and the subsequent need for clopidogrel therapy has not been studied. This is the first case report of acute thrombosis of a drug-coated stent in the mesenteric circulation. Acute mesenteric ischemia secondary to thrombosis of a mesenteric arterial stent following clopidogrel cessation is described. Drug-eluting stents represent an option for mesenteric revascularization in the surgically complicated abdomen. As in the setting of cardiac stenting, acute thrombosis of these devices following cessation of clopidogrel therapy is a concern. Indefinite clopidogrel therapy following deployment of drug-coated stents should be considered.

    Spontaneous dissection of the superior mesenteric artery (SMA) is a rare occurrence, especially when not associated with aortic dissection. Currently, only 28 cases appear to have been reported. Due to the scarcity of cases in the literature, the natural history of isolated, spontaneous SMA dissection is unclear. CT has been reported to be useful for the initial diagnosis of SMA dissection [2-5]. We present two recent cases of spontaneous SMA dissection in which enhanced spiral CT was instrumental in following the disease process and guiding clinical decision making

    A 72-year-old woman with diabetes mellitus was admitted with fever and general fatigue. Blood biochemistry showed elevated hepatic and biliary enzyme levels, abdominal computed tomography showed multiple liver abscesses with portal and superior mesenteric vein thrombosis, and total colonoscopy revealed a submucosal bacterial abscess in the ascending colon. The abscesses were determined to be associated with Enterococcus faecalis infection. The patient was treated conservatively with antibiotics (meropenem) and anticoagulants (warfarin), which led to a gradual amelioration of symptoms and resolution of thrombosis.

    Imaging methods provide an important diagnostic basis to clarify mesenteric ischemia. Angiography is the definitive method of investigation in such cases. Other noninvasive methods such as ultrasonography, computed tomography, and magnetic resonance imaging must still prove their importance. We describe three cases of unspezific abdominal pain where the CT shows a mesenteric venous thrombosis with an infarcted bowel. The venous infarcted bowel is clearly demonstrated by CT when other signs for MTV such as ascites, bowel wall thickening, bowel dilatation, and pneumatosis intestinalis are present. CT seems to be a good procedure in order to identify unspecific abdominal pain as being caused by a vascular insufficiency. (orig.) [de

    Full Text Available Objective: to analyze the epidemiology, associated risk factors, clinical presentation, diagnostic methods, treatment, and evolution of patients diagnosed with superior mesenteric venous thrombosis (SMVT at an university hospital in Madrid. Experimental design: retrospective and descriptive study. We review the medical records of patients with this diagnosis in our hospital from January 1998 to December 2002. Data were processed by using the SPSS vs. 11 software. Patients: all thirteen subjects diagnosed with SMVT in that period were included. Results: associated risk factors included tumoral conditions (5 patients, acute abdominal pathology (2, polyglobulia (1, prothrombin gene mutation (1, and anticardiolipin antibodies (1. No predisposing factor was found in 3 patients. Clinical presentation for all patients was abdominal pain, with nausea and vomiting being the second symptom in frequency (7. The diagnosis was reached by abdominal CT (9, arteriography (2, ultrasounds (1, and histology after intestinal resection (1. Treatment with only anticoagulation was initiated in 4 patients, whereas anticoagulation and surgery were performed in 5 cases. In 4 subjects no specific treatment was prescribed and only palliative measures were established due to a baseline end-stage condition. Five patients died, and four of them had a neoplasic condition as associated risk factor. Mortality in our series was 38.5%. Conclusions: SMVT is a very rare disease that is often associated with neoplasic pathology, which influences its high mortality. Due to non specific symptoms, imaging is essential for the diagnosis and the detection of associated risk factors. In our series, computed tomography imaging was the most profitable test.Objetivo: analizar la epidemiología, factores de riesgo asociados, presentación clínica, métodos diagnósticos, tratamiento y evolución en pacientes diagnosticados de trombosis de vena mesentérica superior (TVMS en un hospital

  12. Small bowel varices secondary to chronic superior mesenteric vein thrombosis in a patient with heterozygous Factor V Leiden mutation: a case report.

    Bleeding ectopic small bowel varices pose a clinical dilemma for the physician, given their diagnostic obscurity and the lack of evidence-based medicine to guide therapy. They often occur in the context of portal hypertension, secondary to either liver disease or extrahepatic causes. Rarely is their presence associated with chronic superior mesenteric vein thrombosis and hereditary coagulopathies. A 74-year-old white woman, with a heterozygous Factor V Leiden mutation and no underlying liver disease or portal hypertension, presented over the course of 13 months for recurrent episodes of melena and per rectal bleeding. An initial endoscopy showed a clean-based chronic gastric ulcer, while colonoscopies showed multiple, non-bleeding angioectasias which were treated with argon plasma coagulation. Subsequent video capsule endoscopy and double balloon enteroscopy revealed red wale marks overlying engorged submucosal veins in her distal ileum, consistent with ectopic varices. A chronic superior mesenteric vein thrombus, found via computed tomography venogram, was the cause of the ileal varices. She underwent curative surgical resection of the affected bowel, with no re-bleeding episodes 17 months post-surgery, despite needing lifelong anticoagulation for recurrent venous thromboembolisms. Clinicians should consider ectopic varices in patients who present with obscure gastrointestinal bleeding, even in the absence of portal hypertension or liver disease. In those with a known thrombophilia, patients should be screened for splanchnic thrombosis, which may precipitate ectopic varices.

    Mesenteric panniculitis is an inflammatory process that represents the second stage of a rare progressive disease involving the adipose tissue of the mesentery. Imaging methods used in the diagnosis of mesenteric panniculitis include barium studies, ultrasonography, computed tomography and magnetic resonance imaging. Computed tomography is important for both, diagnosis and evaluation of the extension of the disease and treatment monitoring. Computed tomography findings may vary according to the stage of the disease and the amount of inflammatory material or fibrosis. There is also good correlation between the computed tomography and anatomical pathology findings. The authors studied 10 patients with mesenteric panniculitis submitted to computed tomography. Magnetic resonance imaging was also performed in one patient. In all patients, computed tomography revealed a heterogeneous mass in the mesentery with density of fat, interspersed with areas of soft tissue density and dilated vessels. (author)

    We evaluated immediate and long-term results of percutaneous transluminal angioplasty (PTA) and stent placement to treat stenotic and occluded arteries in patients with chronic mesenteric ischemia. Fourteen patients were treated by 3 exclusive celiac artery (CA) PTAs (2 stentings), 3 cases with both Superior Mesenteric Artery (SMA) and CA angioplasties, and 8 exclusive SMA angioplasties (3 stentings). Eleven patients had atheromatous stenoses with one case of an early onset atheroma in an HIV patient with antiphospholipid syndrome. The other etiologies of mesenteric arterial lesions were Takayashu arteritis (2 cases) and a postradiation stenoses (1 case). Technical success was achieved in all cases. Two major complications were observed: one hematoma and one false aneurysm occurring at the brachial puncture site (14.3%). An immediate clinical success was obtained in all patients. During a follow-up of 1-83 months (mean: 29 months), 11 patients were symptom free; 3 patients had recurrent pain; in one patient with inflammatory syndrome, pain relief was obtained with medical treatment; in 2 patients abdominal pain was due to restenosis 36 and 6 months after PTA, respectively. Restenosis was treated by PTA (postirradiation stenosis), and by surgical bypass (atheromatous stenosis). Percutaneous endovascular techniques are safe and accurate. They are an alternative to surgery in patients with chronic mesenteric ischemia due to short and proximal occlusive lesions of SMA and CA

    Portal vein and mesenteric vein gas are unusual conditions with a complex and nuclear pathogenesis. Mesenteric ischemia frequently causes such pathological conditions but a variety of other causes are known: inflammatory bowel disease, bowel distension, traumatic and iatrogenic injury, intra-abdominal sepsis, and idiopathic conditions. This pathologic entity is favored by intestinal wall alterations, bowel distension and sepsis. The prognosis is frequently fatal, especially when associated with extended bowel necrosis although in the majority of the cases, outcome is favorable without surgery. (author)

    Full Text Available Superior mesenteric artery syndrome involves compression of the third part of the duodenum due to narrowing of the area between the aorta and the superior mesenteric artery (SMA. We will describe the case of a 34-year-old with cerebral palsy who presented with abdominal pain, nausea, vomiting, and weight loss and was diagnosed with SMA syndrome via CT-imaging. With failure of conservative measures, our patient underwent a duodenojejunostomy after which improvement in her weight as well as relief of her abdominal symptoms was noted. Given the rarity of this syndrome, physicians need to keep a high index of suspicion in order to prevent the damaging consequences.

    2017-01-01

    Abstract Rationale: Acute mesenteric vein thrombosis (MVT) is defined as new-onset thrombosis of the mesenteric vein without evidence of collateralization, finally resulting in extensive intestinal infarction. MVT may be idiopathic or be caused by conditions responsible for thrombophilia and acquired risk factors. To date, there have been few reports of MVT after trauma. Herein we describe our experiences treating three patients with MVT. Patient concerns: Case 1 was a 44-year-old man with transverse colon mesenteric hematoma after blunt abdominal trauma. Case 2 was a 55-year-old man with jejunal transection after a traffic accident. Case 3 was a 26-year-old man presented with multiple abdominal stab bowel injury. Diagnoses: A 1-week follow-up abdominal computed tomography scan showed superior mesenteric vein thrombosis in all of three patients. Interventions: All patients were treated with anticoagulant for 3 or 6 months. Outcomes: MVTs were completely resolved without any complications. Lessons: If early diagnosis and treatment could be available, anticoagulation alone might be adequate for the treatment of SMVT associated with trauma. Early anticoagulation in patients with acute SMVT may avoid the grave prognosis observed in patients with arterial thrombosis. PMID:29382004

    To evaluate the sonographic features of mesenteric lymphadenopathy in childhood epidemic aseptic meningitis and to assess their clinical significance. Thirty-three patients (25 male, 8 female: mean age, 8.6 years) with a diagnosis of aseptic meningitis were prospectively evaluated with abdominal ultrasonography for the presence of enlarged mesenteric nodes. The size and number of enlarged mesenteric lymph nodes were analyzed in relationship with the patient's age, between the patients with abdominal pain or diarrhea (16 cases, 48%) and asymptomatic patients (17 cases, 52%). Mesenteric lymphadenopathy was seen in 31 patients (94%), all 16 symptomatic and 15 of the 17 asymptomatic patients. The number of enlarged nodes was most prevalent between 6-10, seen in 16 patients (52%) and the largest node ranged in size from 4 to 8 mm. Among the 31 patients with mesenteric lymphadenopathy, the mean size of the largest node was statistically different between the symptomatic (6.0 mm) and asymptomatic (5.0 mm) groups (p = 0.021). The number of enlarged nodes and the patient's age were not statistically different between the two groups. Mesenteric lymphadenopathy was seen in almost all cases of childhood epidemic aseptic meningitis, and may be related to the mesenteric lymphadenitis caused by enterovirus

    The records of 40 consecutive patients treated at the Princess Margaret Hospital (PMH) between 1979 and 1988 for aggressive fibromatosis were reviewed. The median follow-up was 86 months (range 21-167 months). All surgery was performed at the referring hospitals. Thirty-six underwent an attempt at excision, four were biopsied. Thirty-one had no overt disease after surgery and 26 of these received adjuvant irradiation. Eight were treated with radiotherapy alone, and another was treated with azathioprine and prednisone. Twenty-four (60%) presented with recurrent disease. The overall relapse free rate was 63% at 5 and 10 years. Combined surgery and irradiation had a higher relapse rate than irradiation alone (46% vs. 25%), and a high proportion of failures in the combined group were marginal failures (36%). Relapses following surgery alone were (1(5)) (20%), and chemotherapy(0(1)) . Tumour size greater than 8 cm predicted for relapse (p 0.002), but tumour site, status of surgical margins, and presence or absence of a history of relapse were not statistically significant. Twelve with subsequent treatment failure underwent successful salvage surgery, and (37(40)) (92%) were disease free at last follow-up. A functional assessment (modified Johnstone scale) revealed(11(24)) patients (46%) with poor functional outcomes (grade 2 or less) after all treatment compared with (6(24)) (25%) at referral. Ten of 11 (91%) with grade of 2 or less had a history of recurrence, and (4(5)) amputations were for treatment of a painful recurrence. Treatment planning in this study was hampered by inadequate information on tumour location since few patients had clinically apparent disease when seen by the radiation oncologist (only 35% of cases) and fewer had preoperative cross-sectional imaging available (12% of cases). Relapse was also associated with a poor functional outcome. Attaining high rates of local control with good functional outcomes requires a thorough pretreatment assessment of

    The purpose of this study is to review multidetector computed tomography (CT) imaging findings of mesenteric venous thrombosis occurring following bariatric surgery. To our knowledge, this complication has not been described in the radiologic literature. Multidetector CT examinations of 6 patients known to have developed mesenteric venous thrombosis after laparoscopic bariatric surgery were reviewed. The thrombus was characterized, and associated imaging findings including presence of mesenteric edema, small bowel edema, and thrombotic complications were described. Four patients underwent laparoscopic sleeve gastrectomy approximately 12 days before CT diagnosis of mesenteric thrombosis and 2 patients had a laparoscopic Roux-en-Y gastric bypass approximately 11 years before imaging diagnosis of mesenteric thrombosis.The thrombus occupied the entire length of the superior mesenteric vein in all cases. Extension into jejunal branches was present in 4 cases. The thrombus was completely occlusive in 4 of 6 patients. Mesenteric venous thrombosis is an increasingly recognized complication of laparoscopic bariatric surgery. Awareness demands that postbariatric surgery patients with acute abdominal pain be studied with intravenous contrast material.

    Computed tomography (CT) provides noninvasive information in the evaluation of abnormalities of the gastrointestinal tract by direct imaging of the bowel wall and adjacent mesentery. Several prior studies have discussed the variable CT appearances of mesenteric abnormalities, such as lymphoma, metastasis, inflammatory disease and edema. Although mesenteric thickening was mentioned in these studies, no study has provided a detailed analysis of the CT appearance of the thickened mesentery. Two characteristic types of mesenteric thickening were identified in 47 patients. Type I is 'intramesenteric thickening', which was noted in 25 patients with vascular obstruction, inflammatory disease and edema. Type II is 'mesenteric surface thickening', which was noted in 22 patients with peritonitis carcinomatosa, peritoneal mesothelioma, tuberculous peritonitis and pseudomyxoma peritoneai. An understanding of these two types of mesenteric diseases is important in the identification of mesenteric pathology. (author).

    2010-01-01

    Full Text Available Aggressive fibromatosis (AF or desmoid tumor is a rare condition, characterized by deep tissue invasion by a monoclonal fibroblastic neoplasm, developed from musculoaponeurotic structures. Surgery is the treatment of choice, but negative margins can hardly been achieved in large tumors, and can lead to major functional disability. AF medical therapy includes nonsteroids anti-inflammatory drugs, tamoxifen, with inconsistent results. Several reports of imatinib efficacy in AF appear in the literature. Here, we describe for the first time a V530I KIT exon 10 mutant that was associated to a dramatic imatinib response in an extraabdominal aggressive fibromatosis. The previously discovered V530I substitution was characterized in the core binding factor AML, but had never been reported in any other condition, so far. In this paper, we discuss the KIT exon 10 mutations or polymorphisms that have been described in a variety of KIT-related conditions, including acute myelogenous leukemia, mastocytosis, and aggressive fibromatosis.

    2011-11-15

    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.

    Mesenteric vessels, including the superior mesenteric artery (SMA) and vein (SMV), provide and drain the rich blood supply of the midgut and hindgut. SMA and SMV injuries are rare and often lethal. Clinical management of these injuries is not well established, but treatment options include operative, non-operative, and endovascular strategies. A narrative review of the literature was conducted using MEDLINE Complete-EBSCO. Relevant studies, specifically those focusing on diagnosis and management of SMA and SMV injuries, were selected. Only original reports and collected series were selected to prevent duplication of cases. A search of the literature for mesenteric arterial injuries yielded 87 studies. Vessel-specific breakdown of the studies yielded 40 with SMA injuries and 41 with SMV injuries. These searches were winnowed to 26 individual studies, which were included in this collective review. Limitations of this study are similar to all narrative literature reviews: the dependence on previously published research and availability of references as outlined in our methodology. Although historically rare, mesenteric vessel injuries are seen with increasing incidence and continue to present a challenge to trauma surgeons due to their daunting mortality rates. Currently, universal treatment guidelines do not exist, but the various options for their management have been extensively reviewed in the literature.

    2016-01-01

    Full Text Available Mesenteric panniculitis is a rare inflammatory and fibrotic process that affects the small intestine mesentery. It may occur following abdominal surgery or in association with a variety of conditions, including malignancy, infection, and certain autoimmune and inflammatory conditions. Herein, an unusual case of mesenteric panniculitis in a patient with primary Sjögren’s syndrome will be presented. The patient presented with abdominal pain, weight loss, sicca symptoms, fatigue, and arthralgia. An abdominal CT revealed mesenteric fat stranding and prominent lymph nodes of the small intestine mesentery. She was found on laboratory workup to have positive antinuclear and anti-SSa antibodies. Minor salivary gland lip biopsy revealed focal lymphocytic sialadenitis. The patient’s symptoms and CT findings improved with corticosteroids. This case suggests that Sjögren’s syndrome should be considered as an underlying disease process in the evaluation of patients with mesenteric panniculitis.

  13. Mesenteric ischaemia after endovascular coiling of ruptured cerebral aneurysms.

    2012-02-03

    Three patients were referred to a national neurosurgical centre following CT evidence of subarachnoid haemorrhage. The three patients, who were referred from different institutions within a seven week period, were Fisher grade 3 and WFNS Grade I at all times. Angiography showed a PCOM aneurysm in one case, a ruptured Basilar tip aneurysm and an unruptured ACOM aneurysm in another case, and an ACOM aneurysm in the third case. It was decided that the aneurysms were suitable for endovascular coiling. These patients had unremarkable intraoperative catheterizations and coiling but subsequently deteriorated post-operatively due to mesenteric ischaemia. Two patients required colectomy for mesenteric ischaemia, and the third arrested secondary to sepsis from bowel perforation. We discuss the various causes that may explain this association, and we alert the neurosurgical community for this complication which has not been reported before.

    2009-01-01

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

    Acute portal vein and mesenteric vein thrombosis (PVMVT) can cause acute mesenteric ischemia and be fatal with mortality rate of 37%-76%. Therefore, early diagnosis and prompt venous revascularization are warranted in patients with acute symptomatic PVMVT. Due to advances in catheter-directed treatment, endovascular treatment has been used for revascularization of affected vessels in PVMVT. We report two cases of symptomatic PVMVT treated successfully by transhepatic percutaneous mechanical thrombectomy-assisted thrombolysis. PMID:24949327

    A 9 mo old female intact English mastiff (case 1) presented for anorexia and vomiting for 7 days. A 7 mo old male castrated American bulldog (case 2) presented for vomiting and anorexia for 2 days without diarrhea. Both dogs were diagnosed with mesenteric volvulus based on exploratory laparotomy, which also revealed an intestinal foreign body obstruction. Case 1 required critical care support during recovery but was ultimately discharged, whereas case 2 had an uncomplicated recovery. Both were reported to be back to normal 1 wk after surgery. Case 1 survived 3 mo and then died due to a colonic torsion diagnosed by exploratory laparotomy. Case 2 has been reported to be completely normal more than 18 mo after surgery. These two cases illustrate that mesenteric volvulus can be present with a several-day history of gastrointestinal signs and that shock may be absent on presentation. This is also the first published report of mesenteric volvulus with a concurrent foreign body obstruction.

    Hormone replacement therapy increases risk of deep venous thrombosis (DVT) mainly in the extremities and lungs. There are reports of mesenteric ischemia secondary to oral contraceptive pills but no reports on hormone replacement therapy and mesenteric thrombosis. The authors present a case of a 44-year-old obese (BMI 32) woman, on long-term hormone replacement therapy, presented with thrombosis of portal, splenic and superior mesenteric veins. She underwent surgical resection of ischemic bowel and planned re-look laparotomies with further resections and jejuno-ileal anastomosis at final laparotomy. Thorough haematological investigations were normal. The authors conclude that hormone replacement therapy in obese patients with no other risk factors can cause a catastrophic mesenteric thrombosis. Aggressive surgical resection with re-look laparotomies and further resections can be lifesaving.

    The so-called non-occlusive disease (NOD) or non-occlusive mesenteric ischemia (NOMI) is a severe and life-threatening pathology. Even under optimal circumstances and standardised diagnostic and therapeutic procedures maximum survival rates do not exceed 50%. The NOD is a pathology of the elder patient and its incidence rises with other comorbidities such as reduced cardiac output, diabetes and renal insufficiency. Induction of the disease with a severe vasoconstriction of the splanchnic vessels may be a simple cardiac decompensation, a frequent trigger however is a previous heart surgery with consecutive cardiac shock. Early diagnosis is difficult to conduct because of unspecific symptoms. Beside abdominal pain in awake patients, ileus or subileus is remaining the single acute symptom which could be also a consequence of a postoperative paralysis. Laboratory parameters such as leucocytosis and elevated lactat levels are often positive, but unspecific and the latter may be a delayed sign of progressive disease. The only sufficient method for diagnosis implicating a possible treatment option seems to be an immediate angiographic examination. Because of the disappointing results of a solitary surgical approach transarterial medication via catheter is indicated. Depending of the course of the disease only a combination of local mesenteric infusion of vasodilatory drugs and surgical resection of already necrotic bowel promises a successful therapeutic approach and better survival rates.

    Osteoblastoma is an uncommon primary bone tumor that usually presents as a painful lesion in a long bone or in the spine. Osteoblastoma has been reported only twice in the literature in conjunction with systemic fibromatosis. The authors report the case of an 8-year-old girl with suspected Klippel-Trenaunay-Weber syndrome, a rare syndrome of systemic fibromatosis, who presented with a painless thoracic rib lesion that was found to be an osteoblastoma.

    Mesenteric cysts are rare, benign gastrointestinal cystic lesions, which are often non-troublesome and present as an incidental radiological finding. However, surgery is often performed in the acute setting to remove lesions that are symptomatic. This report highlights the case of a large, symptomatic mesenteric cyst managed successfully with initial conservative measures followed by planned elective surgery. A 44-year-old female presented with a four-day history of generalised abdominal pain associated with distension, fever, diarrhoea and vomiting. Computer tomography revealed a large (21.7 cm × 11.8 cm × 14 cm) mesenteric cyst within the left abdomen cavity. She was admitted and treated conservatively with intravenous fluids and antibiotics for four days, which lead to complete symptom resolution. Follow-up at intervals of one and three months revealed no return of symptoms. An elective laparotomy and excision of the mesenteric cyst was then scheduled and performed safely at nine months after the initial presentation. Compared to acute surgery, acute conservative management followed by planned elective resection of a symptomatic mesenteric cyst may prove safer. The withholding of an immediate operation may potentially avoid unnecessary operative risk and should be considered in patients without obstructive and peritonitic symptoms. Our case demonstrated the safe use of initial conservative management followed by planned elective surgery of a mesenteric cyst found in the acute setting, which was symptomatic but was not obstructive or causing peritonitic symptoms.

  1. Indications for radiation therapy and surgery in the treatment of fibromatosis

    1995-01-01

    Purpose: To determine the roles of radiation and surgery in treating fibromatosis (desmoid tumors). Methods and Materials: Records of 92 patients treated at the Massachusetts General Hospital between 1971 and 1992 were analyzed. Treatment consisted of: radiation, 15 tumors; surgery, 37 tumors; radiation plus surgery, 40 tumors. Radiation doses ranged from 10 Gy to 72 Gy, and were delivered as megavoltage external beam, brachytherapy or a combination. Minimum follow up was 1 year (median 6.2 yrs). The margin status of resected specimens included: 14 negative, 11 negative at 18 yrs and 0% for age <18 yrs. Conclusions: Surgery remains the primary treatment of choice for fibromatosis. Radiation therapy, however, is also effective either as a primary treatment or a surgical adjuvent. Additional advantage in recurrence free survival with peri-operative treatment was seen in patients for whom negative margins were not achieved. Thus, radiation might be recommended to these patients, particularly if the lesion is located such that further recurrence and resection could result in a significant functional or cosmetic defect. Radiation would also be recommended as a primary therapy for those in which a primary resection could not be expected without such deficits. It should also be noted when considering the potential consequences of recurrence that these lesions may often fail locally even with negative margins. Of further interest lesions located in the planter or palmer regions appear as a different disease entity, with a very benign course in adults and an extremely aggressive course in children

    Familial growth hormone deficiency provides an opportunity to identify new genetic causes of short stature. Here we combine linkage analysis with whole-genome resequencing in patients with growth hormone deficiency and maternally inherited gingival fibromatosis. We report that patients from three unrelated families harbor either of two missense mutations, c.347G>T p.(Arg116Leu) or c.1106C>T p.(Pro369Leu), in KCNQ1, a gene previously implicated in the long QT interval syndrome. Kcnq1 is expressed in hypothalamic GHRH neurons and pituitary somatotropes. Co-expressing KCNQ1 with the KCNE2 β-subunit shows that both KCNQ1 mutants increase current levels in patch clamp analyses and are associated with reduced pituitary hormone secretion from AtT-20 cells. In conclusion, our results reveal a role for the KCNQ1 potassium channel in the regulation of human growth, and show that growth hormone deficiency associated with maternally inherited gingival fibromatosis is an allelic disorder with cardiac arrhythmia syndromes caused by KCNQ1 mutations.

    2018-03-26

    Acute mesenteric venous thrombosis (MVT) is the rarest cause of acute mesenteric ischaemia, so thrombosis of a variant inferior mesenteric vein (IMV) is especially uncommon in the setting of antiphospholipid syndrome (APS). Here, we present such a case of seronegative APS initially manifesting as an anomalous IMV thrombosis in a 76-year-old woman. Although guidelines support anticoagulation with vitamin K antagonists in these patients, we anticoagulated with rivaroxaban (a direct oral anticoagulant (DOAC)) due to patient preference, which resulted in complete clinical and endoscopic resolution. IMV thrombosis is a rare form of MVT, only two case reports describe successful anticoagulation with DOACs in the setting of MVT and none report APS as an underlying aetiology. Therefore, this case provides the opportunity to review the pathophysiology of MVT, APS and their medical management including current trends in anticoagulation. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Diagnosis and therapy of mesenteric ischaemia as the cause of an acute abdomen is a serious problem because of its 60-80% mortality. The study presents experience with diagnosis and therapy of this disease and it compares its results with those in the literature. Throughout the years 2000-2009, there were 39 patients surgically treated with mesenteric ischaemia (17 men, 21 women, the average age 73 I 9.43). 38.46% of patients underwent resection of small and large bowel, in 33.3% only a part of small intestinum was resected, and in two cases (5.13%), the resection was combined with the embolectomy of artery mesenteric superior. In 23.1% of patients, only an explorative laparatomy was performed, because of an extended affection. Four patients were reoperated (dehiscence of anastomosis, perforation of small bowel, dehiscence of the wound, enterocutaneous fistula). 23% of patients needed ventilation because of postoperative complications such as respiratory insufficiency, sepsis and heart failure. There was 53.8% mortality. The abdominal pain (79%), vomitus (61.5%) and subileus (35.9%) predominated in the clinical picture. Leucocyts were elevated in 58.97% of patients. X ray examination showed non specific findings, and ultrasonography has proven to be successful in 42.3% of cases. Mortality of patients is significantly increased by low success rate of the depictive methods, non-specific clinical picture, co-morbidity in elderly patients and by late arrival to hospital.

  5. Mesenteric vein thrombosis following laparoscopic appendectomy

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Mesenteric vein thrombosis is an uncommon complication following laparoscopic surgery. A review of the literature has shown that there is a higher incidence of thrombosis following laparoscopic bariatric procedures, including the gastric sleeve procedure and roux-en-y gastric bypass surgery. Additionally, pylephlebitis, thrombosis of portal or mesenteric veins, has been described following perforated appendicitis. However no report has described mesenteric vein thrombosis following laparoscopy for nonperforated appendicitis in the pediatric population. The cause of this thrombosis is hypothesized to be secondary to venous stasis secondary to insufflation during laparoscopy.

    The cholinergic neurotransmission within the human mesenteric lymphatic vessels has been poorly studied. Therefore, our aim is to analyse the cholinergic nerve fibres of lymphatic vessels using the traditional enzymatic techniques of staining, plus the biochemical modifications of acetylcholinesterase (AChE) activity. Specimens obtained from human mesenteric lymphatic vessels were subjected to the following experimental procedures: 1) drawing, cutting and staining of tissues; 2) staining of total nerve fibres; 3) enzymatic staining of cholinergic nerve fibres; 4) homogenisation of tissues; 5) biochemical amount of proteins; 6) biochemical amount of AChE activity; 6) quantitative analysis of images; 7) statistical analysis of data. The mesenteric lymphatic vessels show many AChE positive nerve fibres around their wall with an almost plexiform distribution. The incubation time was performed at 1 h (partial activity) and 6 h (total activity). Moreover, biochemical dosage of the same enzymatic activity confirms the results obtained with morphological methods. The homogenates of the studied tissues contain strong AChE activity. In our study, the lymphatic vessels appeared to contain few cholinergic nerve fibres. Therefore, it is expected that perivascular nerve stimulation stimulates cholinergic nerves innervating the mesenteric arteries to release the neurotransmitter AChE, which activates muscarinic or nicotinic receptors to modulate adrenergic neurotransmission. These results strongly suggest, that perivascular cholinergic nerves have little or no effect on the adrenergic nerve function in mesenteric arteries. The cholinergic nerves innervating mesenteric arteries do not mediate direct vascular responses.

    The authors present results of serial quality and quantity microanalyses of bone patterns and dental tissue patterns in patient with desmoid fibromatosis. Methods of absorption spectroscopy, emission spectral analysis and X-ray diffraction analysis with follow-up to x-ray examination are tested. The above mentioned methods function in a on-line system by means of specially adjusted monitor unit which is controlled centrally by the computer processor system. The whole process of measurement is fully automated and the data obtained are recorded processed in the unit data structure classified into index sequence blocks of data. Serial microanalyses offer exact data for the study of structural changes of dental and bone tissues which manifest themselves in order of crystal grid shifts. They prove the fact that microanalyses give new possibilities in detection and interpretation of chemical and structural changes of apatite cell.

    Mesenteric vein thrombosis is a rare but potentially lethal cause of abdominal pain. It is usually caused by prothrombotic states that can either be hereditary or acquired. Testosterone supplementation causes an acquired prothrombotic state by promoting erythropoeisis thus causing a secondary polycythaemia. We report a case of a 59-year-old man with a history of chronic obstructive pulmonary disease (COPD) stage III, who presented with abdominal pain. Evaluation revealed an elevated haemoglobin and haematocrit, a superior mesenteric vein thrombosis on CT and a negative Janus kinase 2 mutation. The patient is currently being treated with 6 months of anticoagulation with rivaroxiban. Although a well-known side effect of testosterone is thrombosis, the present case is used to document in the literature the first case of mesenteric vein thrombosis due to secondary polycythaemia from Androgel in the setting of COPD. 2014 BMJ Publishing Group Ltd.

    We wanted to evaluate the effectiveness of stent placement on the superior mesenteric artery as a treatment for chronic mesenteric ischemia. Seven patients (mean age: 55 years, age range: 43-66 years) with chronic mesenteric ischemia were enrolled between March 2000 and September 2003. All the patients underwent pre-procedure contrast enhanced computerized tomography to evaluate for occlusion or stenosis of the mesenteric arteries and they then underwent an angiographic procedure. A balloon-expandable metal stent was placed in the superior mesenteric artery, and this was combined with balloon angioplasty and thrombolysis. We evaluated the angiographic and procedural success after the procedures. Angiographic and procedural success was obtained in 100% of the patients and the clinical symptoms improved in 100% of the patients. The patency at 6-months and 1-year was 85% and 71%, respectively. The mean follow-up period was 12 months (range: 1-25 months). During the follow-up period, ischemic symptoms recurred in 2 patients, and restenosis in a stent was confirmed with angiography; one patient was successfully treated by stent placement in the celiac artery and the other patient died due to extensive mesenteric thrombosis. For the treatment of chronic mesenteric ischemia, percutaneous stent placement on the superior mesenteric artery showed a favorable result and it was an effective alternative to surgery for the high-risk patients

    1997-01-01

    Purpose: To describe the spectrum of early CT findings of lupus mesenteric vasculitis (LMV) and to assess the utility of CT in the management of this uncommon entity. Methods: Abdominal CT was performed within 1-4 days (average 2.2 days) of the onset of severe abdominal pain and tenderness in 15 women with systemic lupus erythematosus. Prompt high-dose i.v. corticosteroid in 11 patients after the CT diagnosis of LMV was made. CT was performed after abdominal symptoms subsided. Results: Eleven cases revealed CT features suggestive of LMV including conspicuous prominence of mesentric vessels with palisade pattern or comb-like appearance (CT comb sign) supplying focal or diffuse dilated bowel loops (n=11), ascites with slightly increased peritoneal enhancement (n=11), small bowel wall thickening (n=10) with double halo or target sign (n=8). Follow-up CT before high-dose steroid therapy revealed complete or marked resolution of the abnormal CT findings. Conclusion: CT is helpful for confirming the diagnosis of LMV, especially the comb sign which may be an early sign. Bowel ischemia due to LMV is less ominous than previously expected, and the abnormal CT findings were reversible when early diagnosis and prompt i.v. steroid therapy could be achieved. (orig.)

    Juvenile hyaline fibromatosis (JHF) and infantile systemic hyalinosis (ISH) are rare, autosomal recessive disorders of the connective tissue caused by mutations in the gene encoding the anthrax toxin receptor 2 protein (ANTXR2) located on chromosome 4q21. Characteristically, these conditions present with overlapping clinical features, such as nodules and/or pearly papules, gingival hyperplasia, flexion contractures of the joints, and osteolytic bone defects. The present report describes a pair of sibs and three other JHF/ISH patients whose diagnoses were based on typical clinical manifestations and confirmed by histopathologic analyses and/or molecular analysis. A comparison of ISH and JHF, additional thoughts about new terminology (hyaline fibromatosis syndrome) and a modified grading system are also included. Copyright © 2012 Wiley Periodicals, Inc.

    We detail the history and evaluation of a 68-year-old man who had head-to-toe PET/CT scanning that showed a focal area of increased FDG uptake in the left medial foot. This was thought to be recurrence of his melanoma. The patient was asymptomatic. He had a history of malignant melanoma of the right ear, which was removed in 2001. On biopsy, the foot lesion was diagnosed as plantar fibromatosis. Plantar fibromatosis is a benign fibroblastic condition, which can be indistinguishable from malignancy in head-to-toe PET/CT scans. Awareness of their potential appearance on PET and PET/CT will aid in the appropriate staging of oncology patients.

  17. The endovascular therapy of chronic mesenteric ischemia: how much have we known so far

    The purpose of this paper is to collect and summarize the clinical evidence related to the endovascular therapy of chronic mesenteric ischemia. The relevant medical literature in English language were collected through Medline by inputting the subject headings, including 'mesenteric ischemia', 'balloon angioplasty', 'mesenteric stenting' and 'intestinal angina'. The medical documents which reported five or more cases receiving endovascular therapy were enrolled in our study for analysis. A total of 16 series with 328 cases altogether were thus obtained. The therapeutic indication for endovascular intervention in all patients was symptomatic mesenteric arterial stenosis. The technical successful rate was 91%. In 75% patients, the clinical symptoms disappeared after the procedure and repeated intervention was not needed. During the follow-up period, re-stenosis occurred in 28% patients. Complications developed in 9% patients, including dissection, distal embolus, infection, thrombosis, bleeding at puncture site, etc. The mortality at 30 days was 3%. Endovascular intervention is a safe treatment for chronic mesenteric stenosis or occlusion. Stent implantation technique carries a higher technical successful rate. However, there are still about one third patients who will probably develop re-stenosis. (authors)

    Isolated and spontaneous dissection of mesenteric arteries is a rare entity; a little more than 50 cases have been reported in medical literature. There is no therapeutic consensus concerning this type of lesion. In this study, we report the results of our treatment based on a conservative approach. This retrospective study concerns eight patients with dissection of the celiac trunk and/or of the upper mesenteric artery (UMA) who were treated between 2002 and 2006. Because these patients were not presenting with acute intestinal ischemia diagnosed by clinical examination or paraclinical tests (medical imaging/biology) or with vital complications, they were treated with an efficient anticoagulation (heparin followed by anti-vitamin K) for 3 to 6 months. Endovascular or surgical treatment was used as the first option in patients with obvious intestinal ischemia or likely to have an arterial rupture, and also when medical treatment had failed. Clinical and radiological follow-up was at 1 month, 3 months, 6 months, and 1 year and then every year. Seven men and one woman (mean age, 48.2; age range, 38-53 years) were treated. Six patients presented with isolated dissection (celiac trunk=4, UMA=2). One patient had a celiac trunk and a UMA dissection and one had a celiac trunk and a UMA dissection along with a dissection of his two renal arteries. On entering the hospital, a patient was operated on for mesenteric ischemia related to a stenosis of the upper mesenteric artery (upper aortomesenteric bypass); a covered stent was implanted in the celiac trunk of another patient presenting with a contained rupture. Both patients were successfully treated. Six patients were medically treated. One of them required an aortohepatic bypass to treat an aneurysmal evolution of the celiac trunk revealed by a computed tomography scan obtained 1 month after the symptoms had begun. In one patient, the dissection remained stable on imaging. Four patients were cured, with a mean 20.1-month

    Our goal was to assess the value of MRA for detecting stenoses in the celiac (CA) and superior mesenteric (SMA) arteries in patients suspected of having chronic mesenteric ischemia, using an optimized systolically gated 3D phase contrast technique. In an initial study in 24 patients who underwent conventional angiography of the abdominal vessels for different clinical indications, a 3D phase contrast MRA technique (3D-PCA) was evaluated and optimized to image the CAs and SMAs. Subsequently, a prospective study was performed to assess the value of systolically gated 3D-PCA in evaluation of the mesenteric arteries in 10 patients with signs and symptoms of chronic mesenteric ischemia. Intraarterial digital subtraction angiography and surgical findings were used as the reference standard. In the initial study, systolic gating appeared to be essential in imaging the SMA on 3D-PCA. In 10 patients suspected of mesenteric ischemia, systolically gated 3D-PCA identified significant proximal disease in the two mesenteric vessels in 4 patients. These patients underwent successful reconstruction of their stenotic vessels. Cardiac-gated MRA may become a useful tool in selection of patients suspected of having mesenteric ischemia who may benefit from surgery. 16 refs., 6 figs., 4 tabs.

    A 49-year-old man complained of sudden upper abdominal pain but was not given a definitive diagnosis. The day after he was discharged, he noticed left chest pain. An in-depth electrocardiogram indicated acute myocardial infarction, and emergent coronary angiography revealed 99% stenosis of his left coronary artery. An intravascular ultrasound revealed spontaneous coronary artery dissection (SCAD), and the lesion was successfully stented. In an atherosclerosis screening, superior mesenteric artery dissection (SMAD) was confirmed, after which the lesion was successfully stented. This case suggests that SCAD and SMAD might have similar pathological backgrounds. PMID:28566599

Apesar de o Tronco Celíaco (TC ser o vaso mais frequentemente acometido, o tratamento cirúrgico é cada vez menos utilizado. O tratamento endovascular, apesar de possuir perviedade inferior a longo prazo, tornou-se o método de escolha devido à fácil execução e baixo índice de complicações. Relato de Casos: Descreve-se quatro casos de revascularização endovascular do TC com implante de stent em pacientes com sintomas de IMC. A avaliação diagnóstica foi realizada através de angioTC helicoidal. Três casos foram realizados por meio do acesso femoral. O sucesso técnico foi de 100%, entretanto um caso necessitou de conversão para acesso braquial. Houve um caso de migração proximal do stent. Todos os pacientes apresentaram melhora subjetiva dos sintomas. Conclusão: Os métodos de imagem são fundamentais para o diagnóstico e planejamento terapêutico. O tratamento endovascular para as lesões estenóticas do TC é o método de escolha na atualidade, devido aos baixos índices de complicações e aceitável taxa de perviedade primária no curto e médio prazo. A aplicação objetiva de questionários de qualidade de vida, entretanto, é necessária para confirmar a eficácia clínica do tratamento.

    Mesenteric vein thrombosis (MVT) is rare. Its diagnosis is usually difficult and delayed. We report two patients who developed MVT as a complication of an appendicular mass. One of them had appendectomy and developed fever 10 days postoperatively. The other was treated conservatively. An abdominal computerized tomography(CT) scan with intravenous contrast was helpful in diagnosing superior MVT in both patients, which were not suspected. Intravenous contrast should be used when performing CT of an appendicular mass. Special interest should be directed at studying the superior mesenteric vein. Early diagnosis of our patients helped to start early medical treatment with anticoagulation. (author)

    Portal vein and mesenteric vein gas are unusual conditions with a complex and nuclear pathogenesis. Mesenteric ischemia frequently causes such pathological conditions but a variety of other causes are known: inflammatory bowel disease, bowel distension, traumatic and iatrogenic injury, intra-abdominal sepsis, and idiopathic conditions. This pathologic entity is favored by intestinal wall alterations, bowel distension and sepsis. The prognosis is frequently fatal, especially when associated with extended bowel necrosis although in the majority of the cases, outcome is favorable without surgery. (author)

    Aggressive fibromatosis (AF) represents a group of tumors with a variable and unpredictable clinical course, characterized by a monoclonal proliferation of myofibroblastic cells. The optimal treatment for AF remains unclear. Identification and validation of genes whose expression patterns are associated with AF may elucidate biological mechanisms in AF, and aid treatment selection. This study was designed to examine the protein expression by immunohistochemistry (IHC) of four genes, ADAM12, FAP, SOX11, and WISP1, that were found in an earlier study to be uniquely overexpressed in AF compared with normal tissues. Digital image analysis was performed to evaluate inter- and intratumor heterogeneity, and correlate protein expression with histologic features, including a histopathologic assessment of tumor activity, defined by nuclear chromatin density ratio (CDR). AF tumors exhibited marked inter- and intratumor histologic heterogeneity. Pathologic assessment of tumor activity and digital assessment of average nuclear size and CDR were all significantly correlated. IHC revealed protein expression of all four genes. IHC staining for ADAM12, FAP, and WISP1 correlated with CDR and was higher, whereas SOX11 staining was lower in tumors with earlier recurrence following excision. All four proteins were expressed, and the regional variation in tumor activity within and among AF cases was demonstrated. A spatial correlation between protein expression and nuclear morphology was observed. IHC also correlated with the probability of recurrence following excision. These proteins may be involved in AF pathogenesis and the corresponding pathways could serve as potential targets of therapy

    Chronic mesenteric ischemia is a clinical condition caused by obstructive or occlusive disease of the mesenteric vessels, with potentially lethal consequences. We describe a case of open multiple revascularization in a patient affected by antiphospholipid syndrome and diffuse atherosclerosis, with an abdominal aortic aneurism, a contracted kidney, a renal cancer affecting the contralateral kidney, and as a consequence, a chronic renal failure and hypertension. We revascularized the celiac trunk, the superior and inferior mesenteric arteries, and the right renal artery using saphenous grafts; the aneurism was corrected, and the renal tumor was treated by radiofrequency ablation. Despite the invasiveness and complexity, the surgical strategy adopted allowed to save the patient's life, to treat the chronic mesenteric ischemia and the renal cancer, and to improve the chronic renal insufficiency and hypertension.

    We used {sup 18}F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec). The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment. Restaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) was performed in parallel using CT and/or MRI and served as reference. The clinical outcomes in nine evaluable patients were as follows: seven patients with stable disease, and two patients with progressive disease. A 27% decrease in the median average standardized uptake value (SUV) of the sequential PET examinations was demonstrated in all evaluable patients with three patients (33%) showing a decrease in SUV of more than 40% (48%, 52% and 54%, respectively); no patient showed a substantial increase in SUV. To our knowledge, this is the first series of AF patients undergoing treatment with imatinib and monitored using sequential PET imaging, that allows detection of SUV changes after imatinib induction, thus helping to decide whether treatment should be continued or not.

    The purpose of this study was to describe the incidence, management, and outcomes of mesenteric artery complications (MACs) during angioplasty and stent placement (MAS) for chronic mesenteric ischemia (CMI). We retrospectively reviewed the clinical data of 156 patients treated with 173 MAS for CMI (1998-2010). MACs were defined as procedure-related mesenteric artery dissection, stent dislodgement, embolization, thrombosis, or perforation. End points were procedure-related morbidity and death. There were 113 women and 43 men (mean age, 73 ± 14 years). Eleven patients (7%) developed 14 MACs, including distal mesenteric embolization in six, branch perforation in three, dissection in two, stent dislodgement in two, and stent thrombosis in one. Five patients required adjunctive endovascular procedures, including in two patients each, catheter-directed thrombolysis or aspiration, retrieval of dislodged stents, and placement of additional stents for dissection. Five patients (45%) required conversion to open repair: two required evacuation of mesenteric hematoma, two required mesenteric revascularization, and one required bowel resection. There were four early deaths (2.5%) due to mesenteric embolization or myocardial infarction in two patients each. Patients with MACs had higher rates of mortality (18% vs 1.5%) and morbidity (64% vs 19%; P thrombosis (odds ratio, 0.2; 95% confidence interval, 0.06-0.90). Patients treated by a large-profile system had a trend toward more MACs (odds ratio, 1.8; 95% confidence interval, 0.7-26.5; P = .07). MACs occurred in 7% of patients who underwent MAS for CMI and resulted in higher mortality, morbidity, and longer hospital length of stay. Use of antiplatelet therapy reduced the risk of distal embolization or vessel thrombosis. There was a trend toward more MACs in patients who underwent interventions performed with a large-profile system. Copyright © 2012 Society for Vascular Surgery. Published by Mosby, Inc.

    We herein report a case of phlegmonous gastritis secondary to superior mesenteric artery syndrome. An 80-year-old woman visited the hospital emergency department with the chief complaints of epigastric pain and vomiting. She was hospitalized urgently following the diagnosis of superior mesenteric artery syndrome based on abdominal computed tomography findings. Conservative therapy was not effective, and phlegmonous gastritis was diagnosed based on the findings of upper gastrointestinal endoscopy and biopsy performed on the 12th day of the disease. Undernutrition and reduced physical activity were observed on hospital admission, and proactive nutritional therapy with enteral nutrition was started. An upper gastrointestinal series, performed approximately 1 month later, confirmed the persistence of strictures and impaired gastric emptying. Because conservative therapy was unlikely to improve oral food intake, open total gastrectomy was performed on the 94th day of the disease. Examination of surgically resected specimens revealed marked inflammation and fibrosis, especially in the body of the stomach. Following a good postoperative recovery, the patient was able to commence oral intake and left our hospital on foot approximately 1 month after surgery.

    We report a case of a 73 year-old man admitted for acute mesenteric ischaemia. Eight years before, he had a first mesenteric ischaemic event treated by left colectomy and angioplasty of both main coeliac artery (MCA) and superior mesenteric artery (SMA); the patient was discharged on lifelong clopidogrel and aspirin. One month before his admission for the index event, he had a major haematuria; clopidogrel was stopped first, then aspirin because of recurrent haematuria. Five days after withdrawal of both antiplatelet drugs, the patient presented with acute mesenteric ischaemia. Urgent aortography showed in-stent occlusion of SMA and in-stent restenosis of MCA; we performed ad hoc thrombus aspiration of SMA and balloon angioplasty of MCA. The patient was discharged seven days after, without complications. This case shows that very late stent thrombosis in digestive artery can occur in the setting of antiplatelet arrest and urgent endovascular intervention constitutes a seductive alternative for surgery when performed early after symptoms onset.

    Objective: To investigate risk factors of mesenteric venous thrombosis and current situation of diagnosis and treatment in China. Methods: One hundred and seven case of mesenteric venous thrombosis reported in literature were analyzed. The literature from 2003 to 2007 were retrieved from Chinese Scientific and Technical Periodical Database and Wanfangdata. Results: One hundred and seven papers included 978 MVT patients, male: female = 1. 9:1, the average age was 47. 9. The most common risk factors were portal hypertension (28. 9% ), splenectomy (18. 8%) and thrombophlebitis (11. 5%) in 833 cases with integrated medical history. Final diagnosis was established by medical imageology (40. 0%) and exploratory laparotomy (60. 0%). The achievement ratio of thrombolysis therapy was 83. 9% (73 /87) by peripheral vein and 90. 0% (63 /70) by superior mesenteric artery. 34. 7% patients took warfarin orally after discharge. Conclusions: Portal hypertension, splenectomy and thrombophlebitis may be the most common risk factor for MVT; through peripheral vein or superior mesenteric artery urokinase thrombolytic therapy is an effective means of treatment of early MVT; MVT diagnostic awareness and anticoagulant therapy after surgery awareness of the importance is to be strengthened.

    Full Text Available Superior mesenteric vein thrombosis (SMVT is a rare yet frequently fatal cause of intestinal ischemia. Despite its severe consequences, SMVT often presents with nonspecific symptoms such as nausea, vomiting, and abdominal pain. It can occur with or without gastrointestinal bleeding, and symptoms may be present for hours to weeks. Physical exam can vary from a benign to an acute abdomen. The are no specific diagnostic laboratory studies for the presence of MVT, and it can be an incidental finding of computed tomography or ultrasound. Patients at risk for MVT include those with a history of a hypercoagulable state or secondary cases such as sepsis, gastrointestinal malignancy, liver disease, pancreatic pathology, abdominal surgery and medications. The authors present a case of a patient presenting with acute abdominal pain and ultimately a SMVT secondary to oral contraceptives by exclusion.

    To analyze the clinical characteristics of patients with mesenteric venous thrombosis related to autoimmune disease (AID). Retrospective study of 5 AID patients with mesenteric vein thrombosis in a single hospital. All 5 patients were female with an average age of 57.6 years. At the clinical visit all patients had clinical manifestations with signs of mesenteric blood vessel involvement and a significant increase of inflammatory markers. Surgical exploration identified peritonitis in all 5 cases - 2 cases of intestinal stenosis with mucosal ulcers and 3 cases of intestinal necrosis complicated by perforation. All 5 patients underwent partial bowel resection. Pathological examination confirmed chronic inflammation and vasculitis of intestinal connective tissue, combined with the formation of mesenteric vein thrombosis. Mesenteric vein thrombosis is a serious complication of AID. AID patients with digestive tract symptoms should be screened by abdominal imaging. In addition to early hormonal therapy and immunosuppressant treatment of the primary disease, surgical treatment should be performed as soon as possible if the disease progresses.

    To evaluate the effectiveness of treatment options for Acute Mesenteric Ischemia and establish proper treatment guidelines. From January 2007 to May 2010, 14 patients (13 men and 1 woman, mean age: 52.1 years) with acute mesenteric ischemia were enrolled in this study. All of the lesions were detected by CT scan and angiography. Initially, 4 patients underwent conservative treatment. Eleven patients were managed by endovascular treatment. We evaluated the therapeutic success and survival rate of each patient. The causes of ischemia included thromboembolism in 6 patients and dissection in 8 patients. Nine patients showed bowel ischemia on CT scans, 4 dissection patients underwent conservative treatment, 3 patients had recurring symptoms, and 5 dissection patients underwent endovascular treatment. Overall success and survival rate was 100%. However, overall success was 83% and survival rate was 40% in the 6 thromboembolism patients. The choice of 20 hours as the critical time in which the procedure is ideally performed was statistically significant (p = 0.0476). A percutaneous endovascular procedure is an effective treatment for acute mesenteric ischemia, especially in patients who underwent treatment within 20 hours. However, further study and a long term follow-up are needed.

  19. Mesenteric venous thrombosis secondary to an unsuspected JAK2 V617F-positive myeloproliferative disorder.

    LENUS (Irish Health Repository)

    2012-01-31

    BACKGROUND: Mesenteric venous thrombosis (MVT) is a rare but potentially fatal cause of mesenteric ischaemia. It presents insidiously and often diagnosis is made at emergency surgery. In half of the cases MVT develops without a causative factor, while in cases in which a pro-thrombotic state is found to exist MVT may be the first clinically detected consequence of that state. The myeloproliferative disorders (MPD) are known to contribute to the development of pro-thrombotic states. Recently, the JAK2 V617F mutation has been associated with the MPDs. CONCLUSION: We describe a case of MVT occurring secondary to an unsuspected MPD, in which the patient was subsequently found to carry this mutation. We highlight the necessity to screen for this mutation in cases of intra-abdominal thromboses so that appropriate systemic anticoagulation may be instituted, and the patient may be followed so as to detect the development of an overt MPD.

The diagnosis of an occlusion of a mesenteric vessel in general is made preoperatively in every fourth patient only. Typical findings are abdominal pains of unknown origin and a distinct discrepancy between the stated complaints, the poor general condition of the patient and the relatively non-contributory examination findings. A known history of cardiac diseases or an arterial occlusive disease is typically found in the event of an occlusion of the mesenteric artery. Patients with a venous thrombosis present with a frequent incidence of thrombophlebitis, coagulation disorders, abdominal inflammations and traumata, or of a tumour.

    Mesenteric ischemia following cardiac surgery is a life-threatening complication. Early identification of patients may help optimizing management and improving outcome. Between January 2000 and July 2007, surgical exploration was realized when mesenteric ischemia was suspected after coronary-artery bypass grafts (CABG). Patients were divided in two groups according to diagnosis confirmation upon laparotomy. Peri-operative predictors of complication and death were analyzed. Of 1634 consecutive patients, 13 (0.8%) developed acute abdomen with suspicion of mesenteric ischemia. Seven (0.4%) underwent resection for ischemic lesions (group 1), of whom two were during a second look laparotomy. The other six patients had normal bowel (group 2). Both groups were comparable according to preoperative status, clinical signs, biological and radiological findings. Delays to laparotomy were 13.7+/-19.0 and 51.4+/-29.0 h in group 1 and 2, respectively (P=0.02). Mortality rates were 46.1% (6/13) overall, 42.8% for group 1 and 50% for group 2. All deaths occurred within the first nine postoperative days. Mesenteric ischemia following CABG is a fatal complication in almost half the cases. Diagnostic tools and timely laparotomy still need to be optimized. Low threshold-based strategy for prompt surgical intervention is efficient for both diagnosis and treatment.

    To summarize our methods and experience with interventional treatment for symptomatic acute-subacute portal vein and superior mesenteric vein thrombosis (PV-SMV) thrombosis. Forty-six patients (30 males, 16 females, aged 17-68 years) with symptomatic acute-subacute portal and superior mesenteric vein thrombosis were accurately diagnosed with Doppler ultrasound scans, computed tomography and magnetic resonance imaging. They were treated with interventional therapy, including direct thrombolysis (26 cases through a transjugular intrahepatic portosystemic shunt; 6 through percutaneous transhepatic portal vein cannulation) and indirect thrombolysis (10 through the femoral artery to superior mesenteric artery catheterization; 4 through the radial artery to superior mesenteric artery catheterization). The blood reperfusion of PV-SMV was achieved completely or partially in 34 patients 3-13 d after thrombolysis. In 11 patients there was no PV-SMV blood reperfusion but the number of collateral vessels increased significantly. Symptoms in these 45 patients were improved dramatically without severe operational complications. In 1 patient, the thrombi did not respond to the interventional treatment and resulted in intestinal necrosis, which required surgical treatment. In 3 patients with interventional treatment, thrombi re-formed 1, 3 and 4 mo after treatment. In these 3 patients, indirect PV-SMV thrombolysis was performed again and was successful. Interventional treatment, including direct or indirect PV-SMV thrombolysis, is a safe and effective method for patients with symptomatic acute-subacute PV-SMV thrombosis.

    Full Text Available An acute disorder of mesenteric circulation is a serious disease with high mortality. It occurs much more often due to the arterial flow impairment, and less often due to the venous blood flow disturbance. Etiology: thrombosis, embolism, compression of the lumen under dissection. To restore the mesenteric blood flow endovascular techniques are performed: mechanical recanalization, balloon angioplasty, stent installation, thrombolysis, tromboaspiration and their various combinations. If recanalization of the superior mesenteric artery is unable to be performed, hybrid operations are carried out anterogradely: retrograde stent installation during laparotomy. The review shows that endovascular methods is a promising direction of treatment for acute mesenteric ischemia.

    Sclerosing mesenteritis is characterized by non-specific inflammation of the mesenteric fat associated with variable amount of fibrosis. The aetiology is unclear; the pathogenesis is obscure, and even its nomenclature remains variable. It is a rare condition with imaging features that can be mistaken either for a mesenteric neoplasm or for a wide variety of non-neoplastic inflammatory conditions. Knowledge of the imaging features of this condition may prevent unwarranted aggressive therapy. This review discusses the pathogenesis, clinical manifestations of this condition, as well as illustrating the characteristic computed tomography (CT) features of sclerosing mesenteritis. A rational approach to the differential diagnosis is discussed

    Imaging methods provide an important diagnostic basis to clarify mesenteric ischemia. Angiography is the definitive method of investigation in such cases. Other noninvasive methods such as ultrasonography, computed tomography, and magnetic resonance imaging must still prove their importance. We describe three cases of unspezific abdominal pain where the CT shows a mesenteric venous thrombosis with an infarcted bowel. The venous infarcted bowel is clearly demonstrated by CT when other signs for MTV such as ascites, bowel wall thickening, bowel dilatation, and pneumatosis intestinalis are present. CT seems to be a good procedure in order to identify unspecific abdominal pain as being caused by a vascular insufficiency. (orig.)

    A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question addressed was whether the thoracic aorta is a safe site for the proximal anastomosis when bypassing the mesenteric arteries in patients with chronic mesenteric ischaemia. Five articles reported the use of the thoracic aorta as the site of proximal anastomosis in 35 patients with chronic mesenteric ischaemia. All of these studies were retrospective case reports or case series. The ascending aorta was the site for the proximal anastomosis in 7 patients with the descending thoracic aorta being used in the other 28 patients. The ascending aorta was used when there was disease of the descending thoracic aorta. Out of the 35 patients there was only 1 perioperative death (3%). Rates of graft patency and freedom from recurrent symptoms were excellent. The published literature supports the use of the thoracic aorta as an option for the site of the proximal anastomosis when bypass from elsewhere is not possible. © The Author 2017.

    Full Text Available A 10-year-old girl presented with a noisy breathing noticed from birth and failure to thrive. Examination revealed a huge lobulated firm mass in the oropharynx (toward the left side. Plain radiography of the neck showed a huge circumscribed pharyngeal mass extending from the base of the tongue to the level of the fourth cervical vertebrae. The mass measuring 6 cm Χ 5 cm was excised through a left lateral pharyngotomy. Histological examination showed sections of highly cellular interlacing bundles of fibroblast with moderate hyalinization extending to the surrounding fibro-fatty tissue. The cells have spindle nuclei with tapering ends. Occasional mitosis and in some areas myxoid degeneration were seen. A diagnosis of pharyngeal fibroma was made. Patient had an uneventful post-operative recovery with complete resolution of symptoms for the past 6 years. This rare benign tumor has not previously been reported at this site and may thus give rise to difficulty in diagnosis or to a misdiagnosis.

    This case report describes a young man who presented with 9-day history of sudden-onset epigastric and right-sided lower abdominal pain. He was tachycardiac with temperature of 102°F. Tenderness was present in the peri-umbilical area and right iliac fossa. Investigations revealed a raised total leucocyte count (predominantly neutrophilic). Triphasic CTscan abdomen found thrombosis of right portal vein and its hepatic tributaries alongwith superior mesenteric vein (SMV) and its tributaries. Co-existent fluid in right hemipelvis abutting the cecum and appendiceal tip was suggestive of acute appendicitis. He was resuscitated with fluids and analgesics and started on intravenous metronidazole and ceftriaxone. Anticoagulation with subcutaneous heparin was commenced and eventually switched over to warfarin. Appendicectomy was not performed as the patient responded to conservative treatment. Appendicitis is associated with multiple complications but secondary venous thrombosis has rarely been reported with it.

    The outcome of desmoid-type fibromatosis (DTF) is unpredictable. Currently, a wait-and-see approach tends to replace large en bloc resection as the first therapeutic approach. Nevertheless, there are no validated factors to guide the treatment choice. We conducted a prospective study of 771 confirmed cases of DTF. We analysed event-free survival (EFS) based on the occurrence of relapse after surgery, progressive disease during the wait-and-see approach, or change in therapeutic strategy. Identification of prognostic factors was performed using classical methods (log-rank test and Cox model). Overall, the 2-year EFS was 56%; this value did not differ between patients undergoing an operation and those managed by the wait-and-see approach (53% versus 58%, p = 0.415). In univariate analysis, two prognostic factors significantly influenced the outcome: the nature of diagnostic sampling (p = 0.466) and primary location (p = 0.0001). The 2-year EFS was only 32% after open biopsy. The 2-year EFS was 66% for favourable locations (abdominal wall, intra-abdominal, breast, digestive viscera and lower limb) and 41% for unfavourable locations. Among patients with favourable locations, the 2-year EFS was similar in patients treated by both surgery (70%) and the wait-and-see approach (63%; p = 0.413). Among patients with unfavourable locations, the 2-year EFS was significantly enhanced in patients initially managed with the wait-and-see approach (52%) compared with those who underwent initial surgery (25%; p = 0.001). The location of DTF is a major prognostic factor for EFS. If these findings are confirmed by independent analysis, personalised management of DTF must consider this easily obtained parameter.

    The intestinal lymph pathway plays an important role in the pathogenesis of organ injury following superior mesenteric artery occlusion (SMAO) shock. We hypothesized that mesenteric lymph reperfusion (MLR) is a major cause of spleen injury after SMAO shock. To test this hypothesis, SMAO shock was induced in Wistar rats by clamping the superior mesenteric artery (SMA) for 1 h, followed by reperfusion for 2 h. Similarly, MLR was performed by clamping the mesenteric lymph duct (MLD) for 1 h, followed by reperfusion for 2 h. In the MLR+SMAO group rats, both the SMA and MLD were clamped and then released for reperfusion for 2 h. SMAO shock alone elicited: 1) splenic structure injury, 2) increased levels of malondialdehyde, nitric oxide (NO), intercellular adhesion molecule-1, endotoxin, lipopolysaccharide receptor (CD14), lipopolysaccharide-binding protein, and tumor necrosis factor-α, 3) enhanced activities of NO synthase and myeloperoxidase, and 4) decreased activities of superoxide dismutase and ATPase. MLR following SMAO shock further aggravated these deleterious effects. We conclude that MLR exacerbates spleen injury caused by SMAO shock, which itself is associated with oxidative stress, excessive release of NO, recruitment of polymorphonuclear neutrophils, endotoxin translocation, and enhanced inflammatory responses.

    2014-01-01

    Acute conditions affecting the mesenteric vessels can cause abdominal pain and result in significant morbidity and mortality if not diagnosed and treated quickly. As bowel viability depends on patency of the mesenteric vessels, prompt diagnosis is essential. Helical multidetector computed tomography (MDCT) provides a rapid, widely available, non-invasive method to promptly evaluate the mesenteric arteries, veins, and abdominopelvic viscera. Given the value of MDCT in diagnosing vascular disease, it is important the radiologist understand technical and imaging findings of mesenteric vascular injury. Therefore, successful diagnosis hinges on familiarity with MDCT angiography and the extended capabilities of volume rendering and multiplanar reformation. In this review, we illustrate and describe key MDCT findings of congenital, inflammatory, traumatic, infectious, and thromboembolic conditions affecting the mesenteric vasculature in adult patients

    Superior mesenteric vein thrombosis after splenectomy is very rare. In the case described of a patient presenting with acute abdominal pain the diagnosis was made primarily by real-time and Doppler ultrasonography. This reduced the time elapsing before it was recognized that angiography and subsequent thrombectomy were indicated.

    A 69-year-old man was admitted to hospital with abdominal pain. In the four years prior to his presentation, he had undergone repeated transarterial chemoembolizations and injections for hepatocellular carcinoma. He underwent his 8th transcatheter arterial therapy one month prior to admission. Abdominal X-rays and contrast-enhanced computed tomography showed large amounts of small intestinal gas and venous thrombosis from the portal vein to the superior mesenteric vein, respectively. The thrombosis was reduced after anticoagulation therapy (heparin, antithrombin III, danaparoid sodium and warfarin). This is the first case report of paralytic ileus due to superior mesenteric venous thrombosis after transcatheter arterial therapy for hepatocellular carcinoma with an arterioportal shunt.

    Objective: To discuss the diagnostic value of MRI for portal vein (PV) and superior mesenteric venous (SMV) thrombosis. Methods: Twelve patients with portal vein and superior mesenteric venous thrombosis proved by operation and pathology were examined with T 1 WI, T 2 WI, T 2 -weighted fat suppression imaging, MR angiography (MRA) and Gd-DTPA enhanced dynamic MRI. Results: Signals in PV and SMV were detected on T 1 WI and T 2 WI in 12 cases; 3 acute thrombus presented hypo- or isointense on T 1 WI and hyperintense on T 2 WI. Hyperintense on T 1 WI and T 2 WI were showed in 8 subacute thrombus; 1 chronic thrombus presented heterogenous intense on T 1 WI and hypointense on T 2 WI. No enhancement within PV and SMV was found on Gd-DTPA enhanced images. Bowel dilatation was found in 10 cases, bowel hemorrhage in 6, bowel wall thickening in 12, intestinal pneumatosis in 3, ascites in 12, cavernous transformation of the portal vein in 3, hepatic perfusion disorder in 6. Conclusion: MRI is an important and sensitive imaging method for the diagnosis and location of portal vein and superior mesenteric venous thrombosis with intestinal ischemia. (authors)

    Multidetector computed tomography (MDCT) is a useful technique for imaging the inferior mesenteric vein. The aim of the present review was to discuss the normal anatomy and the pathologies of the inferior mesenteric vein, including partial or total thrombosis secondary to inflammation (pyophlebitis) and malignancy, occlusion, dilatation and reversed flow, which are rarely encountered. Optimal reconstruction techniques are also discussed. The pathologies of the inferior mesenteric vein can be clearly demonstrated using MDCT using curved-planar reformatted multiplanar reconstruction (MPR) and minimum intensity projection (MIP) images.

    Endovascular treatment of acute mesenteric ischemia is rarely reported. We report a patient with a 1-year history of chronic mesenteric ischemia who presented with acute worsening of his symptoms and peritoneal signs. Aortography depicted an occlusion of the superior mesenteric artery, which was successfully managed with immediate percutaneous angioplasty (PTA) and stent placement. The patient's clinical condition improved markedly and an exploratory laparotomy performed the following day confirmed the viability of the intestine. He remains symptom-free 12 months after the procedure, and color Doppler follow-up showed that the stent is patent

    Superior mesenteric vein injuries are rare and incur high mortality. Given their low incidence, little data exist delineating indications for when to institute primary repair versus ligation. The purposes of this study are to review our institutional experience, to determine the additive effect on mortality of associated vascular injuries, to correlate mortality with the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) for abdominal vascular injury and to examine and define the indications and outcomes for primary repair versus ligation. Retrospective 156 months study (January 1992 through December 2004) in a large Level I urban trauma center of all patients admitted with superior mesenteric vein injuries. Patients were stratified, according to surgical technique employed to deal with their injuries, into those undergoing primary repair versus ligation to determine outcomes and define the surgical indications of these methods. The main outcome measure was overall survival. Cases of survival were stratified according to surgical method: primary repair versus ligation. There were 51 patients with a mean Injury Severity Score of 25 +/- 12. Mechanism of injury was penetrating for 38 (76%), blunt for 13 (24%), and patients undergoing emergency department thoracotomy for 4 (8%). Surgical management was ligation for 30 (59%), primary repair for 16 (31%), and 5 (10%) patients were exsanguinated before repair. The overall survival rate was 24/50 (47%). The survival rate excluding patients undergoing emergency department thoracotomy was 51%. The survival rate excluding patients that sustained greater than 3 to 4 associated vessels injured was 65%. The survival rates of patients with superior mesenteric vein and superior mesenteric artery was 55% and superior mesenteric vein and portal vein (PV) was 40%. The survival rate of patients with isolated superior mesenteric vein injuries was 55%. Mortality stratified to AAST-OIS grade III, 44%; grade IV

    The purpose of this study was to evaluate the prevalence of mesenteric venous thrombosis (MVT) in the Swiss Inflammatory Bowel Disease Cohort Study and to correlate MVT with clinical outcome. Abdominal portal phase CT was used to examine patients with inflammatory bowel disease (IBD). Two experienced abdominal radiologists retrospectively analyzed the images, focusing on the superior and inferior mesenteric vein branches and looking for signs of acute or chronic thrombosis. The location of abnormalities was registered. The presence of MVT was correlated with IBD-related radiologic signs and complications. The cases of 160 patients with IBD (89 women, 71 men; Crohn disease [CD], 121 patients; ulcerative colitis [UC], 39 patients; median age at diagnosis, 27 years for patients with CD, 32 years for patients with UC) were analyzed. MVT was detected in 43 patients with IBD (26.8%). One of these patients had acute MVT; 38, chronic MVT; and four, both. The prevalence of MVT did not differ between CD (35/121 [28.9%]) and UC (8/39 [20.5%]) (p = 0.303). The location of thrombosis was different between CD and UC (CD, jejunal or ileal veins only [p = 0.005]; UC, rectocolic veins only [p = 0.001]). Almost all (41/43) cases of thrombosis were peripheral. MVT in CD patients was more frequently associated with bowel wall thickening (p = 0.013), mesenteric fat hypertrophy (p = 0.005), ascites (p = 0.002), and mesenteric lymph node enlargement (p = 0.036) and was associated with higher rate of bowel stenosis (p < 0.001) and more intestinal IBD-related surgery (p = 0.016) in the outcome. Statistical analyses for patients with UC were not relevant because of the limited population (n = 8). MVT is frequently found in patients with IBD. Among patients with CD, MVT is associated with bowel stenosis and CD-related intestinal surgery.

    Purpose: To evaluate the feasibility of diagnosing in statu nascendi mesenteric ischemia using diffusion-weighted imaging (DWI) in a porcine model. All experiments were approved by the animal care committee at the district administration. Materials and Methods: Mesenteric blood supply was studied in ten healthy female pigs (weight {proportional_to}50 kg) with artificially induced mesenteric ischemia. In the DSA technique a branch of the superior mesenteric artery was embolized with tissue glue or small particles. DWI was performed using a 1.5 T MR scanner before embolization and 30 and 60 minutes after embolization using a 32-channel receiver coil. ADC maps were calculated for all animals. The findings were correlated to angiographic and autoptic findings. The image quality of DWI was assessed by means of SNR measurements and diagnostic impact by CNR measurements. Results: Embolization of the mesenteric branches was technically successful in all cases. DWI of the bowel was feasible with the applied sequences. In all animals, DWI displayed distinct cytotoxic edema as the earliest sign of ischemia thirty minutes after induction of ischemia. Furthermore, DWI yielded a distinct reduction in the water diffusion coefficient in all animals. Variance analysis showed good correlation between CNR measurements and infarction areas. Autoptic findings could confirm the detected infarction areas by DWI. Conclusion: DWI using parallel imaging techniques is feasible for the early detection of acute mesenteric ischemia. The presented DWI results offer encouraging prospects regarding more rapid disease diagnosis. (orig.)

    The human mesentery is now regarded as contiguous from the duodenojejunal (DJ) to anorectal level. This interpretation prompts re-appraisal of computed tomography (CT) images of the mesentery. A digital model and reference atlas of the mesentery were generated using the full-colour data set of the Visible Human Project (VHP). Seventy one normal abdominal CT images were examined to identify mesenteric regions. CT appearances were correlated with cadaveric and histological appearances at corresponding levels. Ascending, descending and sigmoid mesocolons were identifiable in 75%, 86% and 88% of the CTs, respectively. Flexural contiguity was evident in 66%, 68%, 71% and 80% for the ileocaecal, hepatic, splenic and rectosigmoid flexures, respectively. A posterior mesocolic boundary corresponding to the anterior renal fascia was evident in 40% and 54% of cases on the right and left, respectively. The anterior pararenal space (in front of the boundary) corresponded to the mesocolon. Using the VHP, a mesenteric digital model and reference atlas were developed. This enabled re-appraisal of CT images of the mesentery, in which contiguous flexural and non-flexural mesenteric regions were repeatedly identifiable. The anterior pararenal space corresponded to the mesocolon. The Visible Human Project (VHP) allows direct identification of mesenteric structures. Correlating CT and VHP allows identification of flexural and non-flexural mesenteric components. Radiologic appearance of intraperitoneal structures is assessed, starting from a mesenteric platform.

    1. Exercise reduces splanchnic blood flow, but the mesenteric contribution to this response is uncertain. 2. In nineteen humans, superior mesenteric and coeliac artery flows were determined by duplex ultrasonography during fasting and postprandial submaximal cycling and compared with the splanchnic...... blood flow as assessed by the Indocyanine Green dye-elimination technique. 3. Cycling increased arterial pressure, heart rate and cardiac output, while it reduced total vascular resistance. These responses were not altered in the postprandial state. During fasting, cycling increased mesenteric, coeliac...... the coeliac circulation was not influenced. Postprandial cycling did not influence the mesenteric resistance significantly, but its blood flow decreased by 22 % (0.46 +/- 0.28 l min-1). Coeliac and splanchnic resistance increased by 150 and 63 %, respectively, and the corresponding regional blood flow...

    The increasing frequency of use of CT in patients with acute abdomen is likely to improve the diagnosis of rarely occurring conditions/causes such as superior mesenteric vein thrombosis (MVT). Despite its severe consequences, MVT often presents with nonspecific clinical features. AD, a 64-year-old man was an emergency admission with vague abdominal discomfort of two weeks duration, acute upper abdominal pain, loose stools, fresh rectal bleeding and vomiting. A contrast enhanced abdominal CT showed thrombosis of the proximal portal vein and the entire length of the superior mesenteric vein (SMV) with small bowel ischaemia extending from the terminal ileum to the mid jejunal loops. Tests for paroxysmal nocturnal haemoglobinuria and Janus kinase 2 mutation yielded negative results. AD was readmitted seven months later with small bowel obstruction requiring segmental small bowel resection with end-to-end anastomosis. Abdominal CT had shown complete resolution of MVT but a small bowel stricture. Thrombosis limited to mesenteric veins results in earlier and more frequent development of infarction compared to portal combined with mesenteric venous thrombosis. Most patients may be successfully treated with anti-coagulation therapy alone. However, surgery may be required to deal with intestinal infarction or late sequela of MVT. This case demonstrates that MVT can be reversed by effective anticoagulation. However, the price paid for a mild to moderate effect on the bowel may be significant stricture later on. Patients escaping early bowel resection due to massive MVT leading to bowel infarction may still require resection later due to stricture. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    Patients who have a bowel resection for mesenteric infarction may require parenteral nutrition (PN). This study primarily aimed to determine the aetiological factors for a mesenteric infarction and the effects of restoring bowel continuity on the long-term PN requirements. A retrospective review of data on patients treated for mesenteric infarction from 2000 to 2010. A total of 113 patients (61 women, median age 54 years) were identified. Seventy-four (65%) had a superior mesenteric artery thromboembolism, 25 (22%) had a superior mesenteric vein thrombosis, and 4 (3%) had superior mesenteric artery stricture or spasm. Patients younger than 60 years most commonly had a clotting abnormality (n = 23/46, 50%), whereas older patients had a cardiological risk factor (n = 11/17, 65%). All patients with a jejunostomy required long-term PN. Fifty-seven (49%) patients had restoration of bowel continuity (colon brought into circuit). After this, PN was stopped within 1 year in 20 (35%), within 2 years in 29 (50%) patients and within 5 years in 44 (77%) patients (P = 0.001). A thrombotic tendency is the main etiological factor in most patients younger than 60 years. An anastomosis of the remaining jejunum to the colon can allow PN to be stopped.

    A 52-year-old man presented with recurrent postprandial abdominal pain, sitophobia, and progressive weight loss. Chronic mesenteric ischemia (CMI) due to subtotal occlusion of the superior mesenteric artery (SMA) and flush occlusion of the celiac artery (CA) was diagnosed. Retrograde recanalization of the CA by way of a collateral channel from the SMA was performed using contemporary recanalization equipment. The CA and SMA were then stented, resulting in sustained resolution of CMI-related symptoms.

    Mesenteric venous thrombosis (MVT) is a rare but life threatening form of bowel ischemia. It is implicated in 6%-9% of all cases of acute mesenteric ischemia. The proportion of patients with primary (or idiopathic) MVT varies from 0% to 49%, with a decrease in frequency secondary to more recent availability of newer investigations for hypercoagulability. The presence of factor V Leiden (FVL) and prothrombin G20210A mutations (PGM) have been well documented in these cases. However, there have been scarce case reports describing MVT in heterozygotes of both these mutations occurring simultaneously and its implications on long term management. Our case describes acute MVT in a previously asymptomatic young patient with no prior history of venous thromboembolism. The patient was found to be heterozygous for FVL and PGM and treated with lifelong anticoagulation with warfarin (goal international normalized ratio: 2-3) and avoidance of hormonal contraceptives.

    1983-06-01

    By means of 192 lateral aortograms the vascular morphology of the coeliac and superior mesenteric artery were correlated to age, sex and body weight. Independently of these parameters 90% of the exit angles of the coeliac artery were situated between 15/sup 0/ and 90/sup 0/ degrees with a median of 45/sup 0/. In persons with less than 65 kg body weight the median origin angle of the superior mesenteric artery corresponded to 45/sup 0/, too, whereas in heavier patients they were bigger (60/sup 0/). The vascular diameter and the further course of the superior mesenteric artery significantly depended on the constitutional type. In 40.5% we saw a cranial eccentric stenosis of the coeliac artery. Frequency and intensity were not influenced by age, sex or body weight, but accompanied by smaller origin angles of the coeliac artery and bigger ones of the superior mesenteric artery. In conclusion different catheter shapes in dependence of the constitutional type are recommended for combined coeliac and mesenteric angiography.

    INTRODUCTION: The gastrointestinal manifestations of Henoch-Schonlein purpura (HSP) are well characterised, but their recognition can be difficult when they occur in isolation. Furthermore, HSP can run a more serious course in adults, compared to children, in whom the disease usually occurs. MATERIALS AND METHODS: We describe two cases that illustrate the challenges of HSP with mesenteric vasculitis and the outcome in adults. CONCLUSION: Although self-limiting in most patients, the outcome of HSP in adults can be far from benign and even fatal.

    Superior mesenteric vein (SMV) thrombosis is a rare, potentially life-threatening complication of intra-abdominal infection. Here we present a case of massive SMV thrombosis secondary to appendicitis in a 13-year-old boy. He presented with vague abdominal pain and associated symptoms, persistently elevated serum inflammatory markers and a pyrexia of unknown origin. Sonography proved inconclusive, and a definitive diagnosis was made by abdominal contrast-enhanced computed tomography. He was treated with antibiotics and anticoagulation before interval elective laparoscopic appendectomy. The non-specific nature of the presenting symptoms makes SMV thrombosis an important differential to consider when dealing with such patients.

    Full Text Available : Objective/Background: This report presents a superior mesenteric artery (SMA embolism managed by percutaneous mechanical thrombectomy (PMT. Methods: A 61 year old woman diagnosed with SMA embolism was admitted. Emboli were found in the middle and distal segments of the SMA on abdominal computed tomography angiography. Under local anaesthesia, a 6 F Rotarex system was used to remove the emboli via left brachial artery access. Emboli were successfully removed and patency was restored to the SMA and its branches. Results: Post-operatively, the patient's symptoms were significantly relieved. No post-operative complications were observed and no discomfort was documented during follow-up. Conclusion: Endovascular treatment of SMA embolism using PMT is a feasible and alternative option.

    Conclusion: MDCT and CTA are fast, safe, accurate and non-invasive imaging modalities of choice in patients with suspected mesenteric ischemia which are able to evaluate not only mesenteric vascular structures but also evaluate bowel wall changes and adjacent mesentery, thus detecting the primary cause of mesenteric ischemia that can lead to earlier diagnosis and intervention.

    Full Text Available Acute thrombosis of the celiac artery trunk or elsewhere in mesenteric blood supply is a rare cause of acute abdominal pain. Celiac artery thrombosis carries high mortality and morbidity rates if the diagnosis and treatment are delayed. It is frequently associated with other cardiovascular events. The most common etiology is atherosclerosis. The main goal of the treatment is to revascularize and start the diminished or stopped mesenteric blood flow and to avoid end-organ ischemia. Thrombolysis with urokinase followed by anticoagulation with heparin in an emergency situation can save the life of the patient before surgical intervention.

    To evaluate CT findings of internal hernia. Three patients with internal hernia had abdominal CT scans and two of them had small bowel follow-through examinations. The CT features of two patients with retroanastomotic and one patient with left paraduodenal hernia were evaluated and correlated with small bowel follow-through examinations, and surgical findings. Two patients with retroanastomotic hernia had a history of subtotal gastrectomy with antecolic gastrojejunostomy. The diagnosis of internal hernia was made on the basis of surgical findings in two patients of retroanastomotic hernia, and characteristic barium study findings in one patient of left paraduodenal hernia. The small bowel follow-through examination showed small bowel loops gathered in a circumscribed mass in the left mid-abdomen, and delay in passage through these loops. In case of left paraduodenal hernia, abrupt narrowing of the distal duodenum could be identified. The characteristic CT findings of all three patients were whorling of the mesentery and mesenteric vessels in the left mid-abdomen. In the patient with left paraduodenal hernia, after resolution of the gastrointestinal symptoms, a follow-up CT scan showed spontaneous disappearance of whorling of the mesentery and mesenteric vessels suggesting spontaneous resolution of the hernia. In the other two cases, upon exploration of the abdomen, dilatation of afferent duodenum caused by adhesion between ligament of Treitz and adjacent bowel walls, and retro-anastomotic herniation of the efferent loops were found. The usual diagnosis of internal hernia is based on the appearance of the small bowel follow-through examination. However, we consider that the whorling appearance (we call it whorling sign) of the mesentery and mesenteric vessels on CT scan is also suggestive of internal hernia in patients under clinical suspicion.

    Nonocclusive mesenteric ischemia (NOMI) is known to occupy about 25% to 60% of intestinal infarction. NOMI has been reported to be responsible for 9% of the deaths in the dialysis population and the postulated causes of NOMI include intradialytic hypotension, atherosclerosis and medications, such as diuretics, digitalis and vasopressors. Clinical manifestations, such as fever, diarrhea and leukocytosis, are nonspecific, which makes early diagnosis of NOMI very difficult. Case: A 66-year-old woman on maintenance hemodialysis for 5 years was admitted with syncope, abdominal pain and chilly sensation. Since 7 days prior to admission, blood pressure on the supine position during hemodialysis had frequently fallen to 80/50 mmHg. Four days later, she complained of progressive abdominal pain. Rebound tenderness and leukocytosis (WBC 13900/mm3) with left shift were noted. Stool examination was positive for occult blood. Abdominal CT scan showed a distended gall bladder with sludge. Under the impression of acalculous cholecystitis, she was operated on. Surgical and pathologic findings of colon colon were compatible with NOMI. Because of recurrent intradialytic hypotension, we started midodrine 2.5 mg just before hemodialysis and increased the dose up to 7.5 mg. After midodrine therapy, blood pressure during dialysis became stable and the symptoms associated with hypotension did not recur. Conclusion: As NOMI may occur within several hours or days after an intradialytic hypotensive episode, abdominal pain should be carefully observed and NOMI should be considered as a differential diagnosis. In addition, we suggest that midodrine be considered to prevent intradialytic hypotensive episodes. PMID:10714097

    Proximal resistance vessels, such as the mesenteric arteries, contribute substantially to the peripheral resistance. These small vessels of between 100-400 μm in diameter function primarily in directing blood flow to various organs according to the overall requirements of the body. The rat mesenteric artery has a diameter greater than 100 μm. The myography technique, first described by Mulvay and Halpern(1), was based on the method proposed by Bevan and Osher(2). The technique provides information about small vessels under isometric conditions, where substantial shortening of the muscle preparation is prevented. Since force production and sensitivity of vessels to different agonists is dependent on the extent of stretch, according to active tension-length relation, it is essential to conduct contraction studies under isometric conditions to prevent compliance of the mounting wires. Stainless steel wires are preferred to tungsten wires because of oxidation of the latter, which affects recorded responses(3).The technique allows for the comparison of agonist-induced contractions of mounted vessels to obtain evidence for normal function of vascular smooth muscle cell receptors. We have shown in several studies that isolated mesenteric arteries that are contracted with phenylyephrine relax upon addition of cumulative concentrations of extracellular calcium (Ca(2+)(e;)). The findings led us to conclude that perivascular sensory nerves, which express the G protein-coupled Ca(2+)-sensing receptor (CaR), mediate this vasorelaxation response. Using an automated wire myography method, we show here that mesenteric arteries from Wistar, Dahl salt-sensitive(DS) and Dahl salt-resistant (DR) rats respond differently to Ca(2+)(e;). Tissues from Wistar rats showed higher Ca(2+)-sensitivity compared to those from DR and DS. Reduced CaR expression in mesenteric arteries from DS rats correlates with reduced Ca(2+)(e;)-induced relaxation of isolated, pre-contracted arteries. The data

    Pregnancy is an acquired hypercoagulable state. Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis (MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer (IVF-ET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT. Following resection of the gangrenous portion of the small intestine, anticoagulation therapy with unfractionated heparin and thrombolysis therapy via a catheter placed in the superior mesenteric artery were performed, and the patient underwent an artificial abortion. Oral estrogen had been administered for hormone replacement as part of the IVF-ET procedure, and additional precipitating factors related to thrombosis were not found. Pregnancy itself, in addition to the administered estrogen, may have caused MVT in this case. We believe that MVT should be included in the differential diagnosis of a pregnant patient who presents with an acute abdomen.

  16. Superior Mesenteric Artery Syndrome Improved by Enteral Nutritional Therapy according to the Controlling Nutritional Status Score

    Directory of Open Access Journals (Sweden)

    Kazuhiro Takehara

    2017-11-01

    Full Text Available Superior mesenteric artery syndrome (SMAS is a relatively rare disease that involves bowel obstruction symptoms, such as vomiting and gastric distension, owing to the compression of the third portion of the duodenum from the front by the superior mesenteric artery (SMA and from the rear by the abdominal aorta and the spine. SMAS is diagnosed on the basis of an upper gastrointestinal examination series indicating the obstruction of the third portion of the duodenum or a computed tomography scan indicating the narrowing of the branch angle between the aorta and the SMA (i.e., the aorta-SMA angle. Here, we report the case of a 78-year-old woman diagnosed with SMAS after a laparoscopic right hemicolectomy for cecal cancer, whose condition was improved by enteral nutritional therapy. We used her controlling nutritional status (CONUT score as a nutrition assessment and noted the changes in the aorta-SMA angle over the course of the disease. This patient appeared to develop SMAS, on the basis of a worsened CONUT score and a decreased aorta-SMA angle, owing to the inflammation resulting from the intraoperative dissection of the tissues around the SMA and prolonged postoperative fasting. After the initiation of enteral nutritional therapy, the patient exhibited body weight gain and an improved aorta-SMA angle and CONUT score. Hence, assessment of the aorta-SMA angle and CONUT score is an important preoperative consideration.

    Embryologically, duodenal atresia results from inadequate recanalisation and proliferation of gut epithelius in the 6th week of gestation, while apple-pee atresia of small bowel is a consequence of a vascular accident in subsequent embryonic development, and the two are rather rarely manifested as a joint clinical entity. We present here a 29 week preterm boy admitted to the intensive care unit due to breathing difficulties and low birthweight. Following clinical, radiographic and ultrasound examination, he was diagnosed with duodenal obstruction and subjected to surgical treatment. The exploration of abdominal cavity verified duodenal atresia in the second portion with the absence of third and fourth portions of duodenum, superior mesenteric artery, as well as apple-peel atresia of jejunum. Resection of the apple-peel segment of jejunum was done and the continuity of digestive tube was established by the end-to-end duodeno-ileal anastomosis. This rare case of ours questions the embryology of duodenal atresia suggesting that a mesenteric vascular disruption phenomenon in subsequent embryonic life might be the aetiological factor.

    Cocaine-mediated tissue injury is well established, particularly myocardial ischemia and infarction. Gastrointestinal complications including mesenteric ischemia, ischemic colitis and intestinal perforation occur less frequently. Cocaine-induced visceral arterial thrombosis is a rare finding. We report a case of a 49-year-old chronic cocaine user with superior mesenteric artery (SMA) thrombosis. The patient presented with a 24-h history of abdominal pain, nausea and vomiting. Physical examination documented tachycardia and a soft, non-rigid abdomen with voluntary guarding. Abdominal X-ray did not show any evidence of peritoneal free air or bowel obstruction. Laboratory investigations revealed elevated white blood cells and a high anion gap; a blood gas analysis was not done. Three hours after initial presentation, the patient had a cardiac arrest and died. At autopsy, the jejunum was ischemic, without obvious infarction. The SMA was occluded at its origin by significant atherosclerosis with superimposed thrombus. The myocardium had fibrosis, without acute infarction, and severe triple coronary artery atherosclerosis. Toxicological blood analysis confirmed cocaine use. This report emphasizes the need to consider chronic stimulant drug abuse in accelerated atheroma and thrombosis of visceral arteries.

    PurposeTo evaluate endovascular therapy (EVT) as the primary revascularization method for acute mesenteric ischemia (AMI).MethodsA retrospective review was performed on all consecutive patients treated for AMI during a 5-year period (January 2009 to December 2013). EVT was attempted in all patients referred for emergent revascularization. Surgical revascularization was performed selectively after failure of EVT. Patient characteristics, clinical presentation, and outcomes were studied. Failures and complications of EVT were recorded.ResultsFifty patients, aged 79 ± 9 years (mean ± SD), out of 66 consecutive patients with AMI secondary to embolic or thrombotic obstruction of the superior mesenteric artery were referred for revascularization. The etiology of AMI was embolism in 18 (36 %) and thrombosis in 32 (64 %) patients. EVT was technically successful in 44 (88 %) patients. Mortality after successful or failed EVT was 32 %. The rates of emergency laparotomy, bowel resection, and EVT-related complication were 40, 34, and 10 %, respectively. Three out of six patients with failure of EVT were treated with surgical bypass. EVT failure did not significantly affect survival.ConclusionsEVT is feasible in most cases of AMI, with favorable patient outcome and acceptable complication rate.

  2. Autobuttressing of colorectal anastomoses using a mesenteric flap.

    LENUS (Irish Health Repository)

    Mohan, H M

    2013-12-01

    Anastomotic leakage is a common and dreaded complication of colorectal surgery. Many different approaches have been tried to attempt to reduce leakage and associated morbidity. The concept of reinforcement of an anastomosis by buttressing is well established. Techniques described include using sutures, native omentum, animal or synthetic material. We report a technique for buttressing using a mesenteric flap to envelope the anastomosis. The primary rationale is to reduce clinical sequelae of anastomotic leakage by promoting local containment, as well as providing a scaffold for healing. Using autologous tissue provides a safe, time-efficient and cost-effective buttress without the risks of infection or reaction associated with foreign material. A mesenteric flap is particularly useful in patients in whom omentum is not available due to previous surgery, or to fill the dead space posterior to a low anastomosis within the pelvis.

    A 69-year-old man, with hepatits C virus-related liver cirrhosis and hemophilia B, developed massive ascites and watery diarrhea after endoscopic injection sclerotherapy for esophageal varices. A multi detector row computed tomography revealed a superior mesenteric venous thrombus without bowel infarction. It was assumed that the thrombus was caused by transient congestion of the portal system after retrograde propagation of the sclerosant agent, in a condition where anticoagulation proteins, such as proteins C and S, had decreased. Because long systemic thrombolytic therapy was hazardous for the patient with hemorrhagic diathesis due to impaired coagulation, a direct thrombolysis was performed with urokinase followed by aspiration thrombectomy, with cannulation of the portal venous system using a transjugular intrahepatic approach. The patient had no complications in this procedure and subsequently diarrhea and refractory ascites were resolved. Direct thrombectomy via the transjugular intrahepatic route may be a useful therapy for mesenteric venous thrombus in the cirrhotic patient.

    Full Text Available Abstract Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding.

    Full Text Available Chronic diarrhoeal illnesses with nausea and weight loss are a common indication for gastroenterology review. While many such cases have intra-luminal aetiologies, such as inflammatory bowel disease, coeliac disease or other malabsorptive conditions, with many other cases due to functional gut disorders or systemic malignancy, clinicians must also keep vascular disorders in mind. Here we report a patient with a delayed diagnosis of chronic mesenteric ischaemia after 6 months of gastrointestinal symptoms strongly mimicking an alternative diagnosis such as inflammatory bowel disease due an atypical predominance of nausea and diarrhoea rather than pain. We briefly review the literature on treatment of this condition but also discuss with particular attention the sequence of cognitive errors made by clinicians that led to a diagnostic delay, inviting readers to thus reflect on how such errors can be minimised in their practice.

    Full Text Available Abstract Background Onset of Henoch-Schönlein purpura (HSP in middle age is uncommon, and adults with renal or gastrointestinal involvement present with more severe disease than do similar pediatric patients. Case presentation We present the case of a 69-year-old male with HSP who, after treatment with steroids, cyclophosphamide, and continuous intravenous prostaglandin E1 (PGE1, died as a result of severe gastrointestinal involvement with non-occlusive mesenteric ischemia (NOMI. Vascular narrowing associated with the NOMI improved after catheter injection of PGE1 and prednisolone, but the patient died of bleeding from an exposed small vessel. At autopsy there was no active vasculitis in the jejunal submucosa. Conclusion Treatment with PGE1 and prednisolone might improve small-vessel vasculitis associated with NOMI.

    Full Text Available Thromboembolism is a major complication of nephrotic syndrome. Renal vein thrombosis and deep vein thrombosis are relatively common, especially in membranous nephropathy. However, the incidence of portal vein and superior mesenteric vein (SMV thrombosis in patients with nephrotic syndrome is very rare. To date, several cases of portal vein thrombosis treated by anticoagulation therapy, not by thrombolytic therapy, have been reported as a complication of nephrotic syndrome. Here, we report a case of portal, splenic, and SMV thrombosis in a patient with a relapsed steroid dependent minimal change disease who was treated successfully with anticoagulation and thrombolytic therapy using urokinase. Radiologic findings and his clinical conditions gradually improved. Six months later, a complete remission of the nephrotic syndrome was observed and the follow-up computed tomography scan showed the disappearance of all portal vein, splenic vein, and SMV thrombi.

    Diagnostic imaging and embolization therapy for the uncommon portal and mesenteric vein-inferior vena cave shunt (PV·SMV-IVC shunt) are reported. As the frequency of clinical symptoms such as hematemesis, melena and confusion caused by gastrointestinal varices, or hepatoencephalopathy was about 40%, it was important for this disease entity to be diagnosed with noninvasive diagnostic images. The careful examination of the area around the right renal vein was able to overcome the low diagnostic rate of 20-40% obtained with US and CT images. In cases of simple PV·SMV-IVC shut without gastrointestinal varices, embolization therapy using steel coils and done by the intravenous approach is easy and noninvasive. On the other hand, in cases of complex PV-SMV-IVC shunt with gastrointestinal varices, dual balloon occluded embolization therapy using a liquid sclerosing agent and done by the intravenous and portal approaches is preferable.

    Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose inferior mesenteric vein (IMV) that drained into peri rectal collateral veins, demonstrated by {sup 99m}Tc-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of {sup 99m}Tc-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.

    Isolated dissection of superior mesenteric artery is a rare condition and is usually treated surgically. We treated a patient with severe abdominal pain who was angiographically confirmed to have superior mesenteric artery thrombosis associated with isolated spontaneous dissection. He was treated initially by thrombolysis and oral anticoagulation, but recurrent symptoms developed with radiologic evidence of disease progression. We performed superior mesenteric artery stenting and recovery was uneventful

    Full Text Available Abstract Background Neoplasia can be driven by mutations resulting in dysregulation of transcription. In the mesenchymal neoplasm, aggressive fibromatosis, subtractive hybridization identified sterile alpha motif domain 9 (SAMD9 as a substantially down regulated gene in neoplasia. SAMD9 was recently found to be mutated in normophosphatemic familial tumoral calcinosis. In this study, we studied the gene structure and function of SAMD9, and its paralogous gene, SAMD9L, and examined these in a variety of species. Results SAMD9 is located on human chromosome 7q21.2 with a paralogous gene sterile alpha motif domain 9 like (SAMD9L in the head-to-tail orientation. Although both genes are present in a variety of species, the orthologue for SAMD9 is lost in the mouse lineage due to a unique genomic rearrangement. Both SAMD9 and SAMD9L are ubiquitously expressed in human tissues. SAMD9 is expressed at a lower level in a variety of neoplasms associated with β-catenin stabilization, such as aggressive fibromatosis, breast, and colon cancers. SAMD9 and SAMD9L contain an amino-terminal SAM domain, but the remainder of the predicted protein structure does not exhibit substantial homology to other known protein motifs. The putative protein product of SAMD9 localizes to the cytoplasm. In vitro data shows that SAMD9 negatively regulates cell proliferation. Over expression of SAMD9 in the colon cancer cell line, SW480, reduces the volume of tumors formed when transplanted into immune-deficient mice. Conclusion SAMD9 and SAMD9L are a novel family of genes, which play a role regulating cell proliferation and suppressing the neoplastic phenotype. This is the first report as far as we know about a human gene that exists in rat, but is lost in mouse, due to a mouse specific rearrangement, resulting in the loss of the SAMD9 gene.

    Acute mesenteric venous thrombosis is potentially lethal because it can result in mesenteric ischemia and, ultimately, bowel infarction requiring surgical intervention. Systemic anticoagulation for the prevention of thrombus propagation is a well-recognized treatment modality and the current mainstay therapy for patients with acute mesenteric venous thrombosis. However, the decision between prompt surgical exploration vs conservative treatment with anticoagulation is somewhat difficult in patients with suspected bowel ischemia. Here we describe a patient with acute mesenteric venous thrombosis who presented with bowel ischemia and was treated with anticoagulation and delayed short-segment bowel resection.

    We report a case of previously undiagnosed Yersinia enterocolitica infection in a 46-year old woman. She consulted her physician because of continual weight loss and physical lassitude. A leucocytosis was found. Sonography revealed an excessive enlargement of abdominal lymph nodes. A malignant lymphoma was suspected and the patient underwent a staging by CT. There the disease was limited on mesenteric and retroperitoneal lymph nodes. Bone marrow biopsy and CT-guided lymph node biopsy did not confirm a systemic lymphatic disease. The patient did not undergo a special therapy. After six months, CT showed a clear regression of enlarged lymph nodes. Finally, a previous Yersinia enterocolitica infection of immunotype 03 could be proved serologically. At this time, the patient had no complaints. Diagnostic and differential diagnosis of benign abdominal lymph node enlargement are discussed based on literature. (orig.) [de

    Immunohistochemical staining with conventional anti-β-catenin antibody has been applied as a diagnostic tool for desmoid-type fibromatosis (DF). This study aimed to evaluate the diagnostic and prognostic value of immunohistochemical staining with anti-non-phospho β-catenin antibody, which might more accurately reflect the aggressiveness of DF, in comparison to the conventional anti-β-catenin antibody. Between 2003 and 2015, 40 patients with extra-peritoneal sporadic DF were prospectively treated with meloxicam or celecoxib, a COX-2 inhibitor, therapy. The efficacy of this treatment was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST). Immunohistochemical staining was performed on formalin-fixed material to evaluate the expression of β-catenin and non-phospho β-catenin, and the positivity was grouped as negative, weak, moderate, and strong. DNA was isolated from frozen tissue or formalin-fixed materials, and the CTNNB1 mutation status was determined by direct sequencing. Of the 40 patients receiving COX-2 inhibitor treatment, there was one with complete remission, 12 with partial remission, 7 with stable disease, and 20 with progressive disease. The mutation sites in CTNNB1 were detected in 22 (55%) of the 40 cases: T41A (17 cases), S45F (3 cases), and T41I and S45P (1 each). The positive nuclear expression of non-phospho β-catenin showed a significant correlation with positive CTNNB1 mutation status detected by Sanger method (p = 0.025), and poor outcome in COX-2 inhibitor therapy (p = 0.022). In contrast, nuclear expression of β-catenin did not show a significant correlation with either CTNNB1 mutation status (p = 0.43) or outcome of COX-2 inhibitor therapy (p = 0.38). Nuclear expression of non-phospho β-catenin might more appropriately reflect the biological behavior of DF, and immunohistochemical staining with non-phospho β-catenin could serve as a more useful diagnostic and prognostic tool of COX-2 inhibitor therapy

    Objective: To discuss the significance of inferior mesenteric artery (IMA) in the interventional treatment for unresectable and recurrent ovarian carcinoma. Methods: Thirty-four patients with ovarian carcinoma, including unresectable advanced cases (n = 22) and post operative recurrent cases (n = 12), underwent routine interventional arterial chemotherapy and / or embolization via bilateral internal iliac arteries and / or uterine arteries. Infusion chemotherapy through IMA was carried out if IMA was involved in feeding the tumor. The clinical response was observed and analyzed. Results: Of 34 patients, involvement of IMA in feeding the tumor was found in 26, including 20 recurrent cases and 6 unresectable cases. Three weeks after infusion chemotherapy through IMA, the tumor size judged from CT scans was reduced in certain degree. Of 13 cases with FIGO III stage, 8 had abnormal IMA. Of 21 cases with FIGO IV stage, 18 had abnormal IMA. Conclusion: In advanced ovarian carcinomas, especially in recurrent cases, IMA is usually involved in the blood-supply of the tumor, therefore, in order to improve the therapeutic effect the operators should try to find the IMA during interventional management and to make infusion chemotherapy through IMA.

    Fibromatosis, also known as an extra-abdominal desmoid tumor, rarely occurs in the breast and is often mistaken for carcinoma, clinically and radiologically. Desmoid tumor is a monoclonal myofibroblastic neoplasm which is locally aggressive, but rarely metastasizes. We herein report a case of a 64-year-old woman who experienced two episodes of recurrence of mammary fibromatosis. The mass was initially detected by screening mammography. It appeared as an irregularly shaped mass which was confined within the mammary zone. Recurrences were excised from the right breast 10 and 17 months later. The second recurrence occurred in the subareolar area accompanied by skin thickening and showed an anechoic component on ultrasonography, which mimicked subareolar mastitis with an abscess.

  2. Levobupivacaine induces vasodilatation, but not vasoconstriction, in rat mesenteric artery

    Directory of Open Access Journals (Sweden)

    Liciane dos Santos MENEZES

    Full Text Available Abstract Introduction Levobupivacaine (LEVO can replace analgesia because it exhibits low toxicity and causes minor vasoconstriction, enabling its use in patients in whom vasoconstrictors are contraindicated. Objective We aimed to evaluate the effects of LEVO in isolated rat superior mesenteric artery by using the vascular reactivity technique and compare its effect to that of lidocaine. Material and method Arterial rings were obtained from the mesenteric artery of male Wistar rats and kept in organ baths. For recording isometric contractions, each ring was suspended by cotton threads from a force transducer, which was connected to a data acquisition system. Result Both lidocaine and LEVO did not show a vasoconstrictor effect on the basal tone of the arterial rings with functional endothelium. However, when the rings were pre-contracted with phenylephrine, both drugs were able to induce concentration-dependent vasodilatation. The vasodilator effect induced by LEVO did not change after removal of the endothelium, or with the addition of tetraethylammonium (1 mM, a non-selective K+ channel blocker. In the rings without functional endothelium, which were pre-contracted with depolarizing Tyrode’s solution (KCl 80 mM, LEVO-induced vasodilatation was not significantly different from that observed in the rings pre-contracted with phenylephrine. Moreover, it did not show a significant additional vasodilator effect compared to the maximal vasodilator effect of nifedipine. Conclusion This study demonstrated that LEVO produces a vasodilator effect in the rat superior mesenteric artery in an endothelium-independent manner. This effect seems to be mediated via Ca2+ channel blockade in the vascular smooth muscle cells.

    An 8-year-old terrier cross and a 10-year-old German Shorthaired Pointer presented to the University Veterinary Centre, Sydney, for investigation of long-standing tenesmus and dyschezia. Both patients had an annular adenocarcinoma at the colorectal junction. Exploratory laparotomy was performed and the affected large intestinal segment was removed by resection and anastomosis. In both dogs, the caudal mesenteric artery was intimately associated with the mass, necessitating its ligation and transection. Postoperatively, there was no evidence of anastomosis breakdown in either case and both animals recovered well from surgery. The dogs were euthanased 8 and 10 months, respectively, after surgery because of clinical signs relating to metastatic disease.

Case presentation We report a case of a 25-year-old man with Crohn's disease (CD who developed a superior mesenteric venous thrombosis, multiple liver abscesses and pylephlebitis, diagnosed through abdominal ultrasound and an abdominal computed tomography (CT scan. The patient was successfully treated with conservative treatment consisting of intravenous antibiotics, subcutaneous anticoagulation and percutaneous catheter drainage of liver abscesses. Conclusion We reported an unnusual case of pylephlebitis in CD. Until now this association has not been reported in adult patients at onset. We hypothesise that the infection developed as a result of mucosal disease and predisposed by corticoid therapy. Adequated management was discussed.

    A 58-year-old man with an abscess of the psoas muscle was returned to our hospital with hematemesis. Two years earlier, he had undergone coil embolization for a superior mesenteric artery (SMA) pseudoaneurysm secondary to pancreatitis. Based on the physical examination, serum amylase level, and abdominal radiographs, a diagnosis of acute exacerbation of pancreatitis and coil compaction of the SMA pseudoaneurysm was made. The patient underwent re-embolization for the coil compaction using interlocking detachable coils. His condition improved gradually, and he was discharged 3 weeks later. To our knowledge, this is the first report of coil compaction of SMA pseudoaneurysm. (orig.)

    A middle-aged man was being investigated for constipation. Abdominal radiographs incidentally revealed a large, densely calcified, rounded mass within the pelvic cavity. A CT scan was performed followed by surgical excision with a differential diagnosis of calcified hematoma and an enlarged calcified lymph nodal mass. Histopathological investigation revealed a primary mesenteric extraskeletal osteosarcoma. To the best of our knowledge, a primary extraskeletal osteosarcoma arising from the mesentery has not been described previously in the English literature. The radiological features and differential diagnosis are discussed. (orig.)

  12. Abdominal Aortic Dissection with Acute Mesenteric Ischemia in a Patient with Marfan Syndrome

    Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

  13. Experimental change of reactivity of mesenteric microvessels

    Changes in hemodynamic parameters due to the action of adrenalin in the microcirculatory channel of tissue mesentery treated locally with beta radiation were studied. The studies were made on the mesenteries of 35 white rats (male) weighing 150-250 g. The diameters and linear blood flow rates were measured before irradiation and after application of adrenalin (1:100,000 dilute, 0.15 ml) to the irradiated portions in the same vessels. After irradiation the action of the adrenalin often caused deeper disruption of the blood flow than was observed when it was applied to mesentery tissue of the intact animals. Three to 5 s after application of the adrenalin, in some cases there was a lengthened cessation of blood flow, and then the flow started slowly in the reverse direction. Sometimes the result of the action of the preparation was an irreversible stasis of the blood. In the next 2-3 min there was retardation, and then acceleration, with a jerky blood flow. All changes in the peripheral blood circulation occurred in the narrow vessels, but an ischemia was not observed. Mathematical analysis of the data from our experiments showed that with application of adrenalin on irradiated mesentery tissue the greatest decrease in cross-section area is in the small arterioles (42.5-7.5 μ dia), i.e. 53-43% of the initial value. The cross-section area of the capillaries (7.5-17.5 μ) of the arterial and venous terminals decrease an average of 33-30%. The least reaction was noted in the venules of 42-75 μ (21%). The blood flow rate decreased in all vessels of the microcirculatory channel of irradiated tissue mesentery after application of adrenalin. The greatest decrease was in the arterioles and the precapillaries(42-50%). In the capillaries (7.5-17.5 μ) there was a decrease in blood volume through them of 25-30%, and in the venules (42.5-72.5 μ), 18%. With even a very small ionizing radiation dose, in the tissues there were a number of vaso-active substances (to which

    To review the non neoplastic diseases primarily associated with intraabdominal fat in the attempt to resolve the confusion caused by the wide variety of terms applied to this entity. The most characteristic findings in diagnostic imaging are also presented. Nine patients with this disease were reviewed. The forms of clinical onset were analyzed in every case, as were the radiological images obtained with different imaging techniques (ultrasound CT, MR and gastrointestinal transit). In four patients, the diagnosis was confirmed by pathological study. All the patients underwent follow-up with a favorable outcome; some patients were monitored by CT scan during follow-up. Mesenteric involvement was detected in seven cases and o mental involvement in two. Both diffuse and focal forms were observed. CT disclosed the most characteristics findings. The diffuse form was associated with increased density of the mesenteric fat, which surrounded vessels without infiltrating them. The focal lesions appeared in the form of dense masses in soft tissue and fat, with one or the other predominating depending on the case. The ultrasound and MR findings varied. This is a self-limiting process with characteristic images, particularly in Ct. Thus, it can be diagnosed without surgery or biopsy, unless clinically indicated. (Author) 13 refs

    2014-01-01

    Background Acute thrombosis of the portal vein (PV) and/or the mesenteric vein (MV) is a rare but potentially life-threatening disease. A multitude of risk factors for acute portal vein thrombosis (PVT)/mesenteric vein thrombosis (MVT) have been identified, including liver cirrhosis, malignancy, coagulation disorders, intra-abdominal infection/inflammation, and postoperative condition. Methods This article analyses the treatment options for acute PVT/MVT. Results Initially, the clinical management should identify patients with an intra-abdominal focus requiring immediate surgical intervention (e.g. bowel ischaemia). Subsequently, emphasis is placed on the recanalization of the PV/MV or at least the prevention of thrombus extension to avoid long-term complications of portal hypertension. Several therapeutic options are currently available, including anticoagulation therapy, local/systemic thrombolysis, interventional or surgical thrombectomy, and a combination of these procedures. Due to the lack of prospective randomized studies, a comparison between these therapeutic approaches regarding the efficacy of PV/MV recanalization is difficult, if not impossible. Conclusion In patients with acute PVT/MVT, an individualized treatment based on the clinical presentation, the underlying disease, the extent of the thrombosis, and the patients' comorbidities is mandatory. Therefore, these patients should be considered for an interdisciplinary therapy in specialized centres with the option to utilise all therapeutic approaches currently available. PMID:26285602

    BACKGROUND: A variety of approaches are available for division of major vascular structures during laparoscopic colorectal resection. Ultrasonic coagulating shears (UCS), vascular staplers, plastic or titanium clips and electrothermal bipolar vessel sealing (EBVS) are currently available. We report our experience with an EBVS device, LigaSure (Covidien AG), used in division of the ileocolic, middle colic and inferior mesenteric arteries during laparoscopic colorectal resection. METHODS: We report the immediate outcome of 802 consecutive unselected patients who underwent elective laparoscopic colorectal cancer resection performed with use of the LigaSure (5 and 10 mm) at our institution over a 5-year period. Operative procedures included right hemicolectomy (n = 180), left hemicolectomy (n = 96), sigmoid colectomy (n = 347) and anterior resection (n = 179). Data were collected from a prospectively maintained cancer database and operative records. The procedures were performed primarily by three consultant surgeons with an interest in laparoscopic colorectal resection. RESULTS: Of 802 cases in which the LigaSure device was employed to divide major vascular structures, immediate effective vessel sealing was achieved in 99.8% (n = 800). Two patients experienced related adverse events both following division of the inferior mesenteric artery with a 5 mm LigaSure. Both patients had immediate uncontrolled haemorrhage that required laparotomy. CONCLUSIONS: Use of the LigaSure device to seal and divide the major mesenteric vessels during laparoscopic colorectal resection is very effective, with a high success rate of 99.8%. Caution should be exercised in elderly atherosclerotic patients, particularly when using the 5-mm LigaSure device.

    A 42-year-old man had intestinal ischemia 7 weeks after endovascular abdominal aortic aneurysm repair due to sacrifice of the inferior mesenteric artery, which had compensated for the intestinal blood supply because of the total occlusion of the superior mesenteric artery (SMA) and severe stenosis of the celiac artery (CA). He was diagnosed in the active phase of Takayasu arteritis, and an emergency endovascular treatment was performed. After the SMA failed to be recanalized, a stent was successfully placed into the CA; this choice was made based on the preexisting collaterals between them. The symptoms were relieved shortly after the operation. The Kirk arcade, the Barkow arcade, and the enlarged pancreaticoduodenal arcade were visualized on the follow-up computed tomography angiography. Based on this case, a short review of celiomesenteric and intermesenteric collateral circulations is presented. © The Author(s) 2016.

    Nonocclusive mesenteric ischemia (NOMI) is accompanied by mesenteric artery spasms that are at least in part due to endothelin system activation. Acute treatment includes intra-arterial infusion of vasodilators such as iloprost, prostaglandin E1 (PGE1), and papaverine. Their effectiveness is not well characterized in human mesenteric arteries. We directly compared their potency to relax isolated human mesenteric arteries. To explore the potential of Rock inhibition to treat mesenteric artery spasms, we tested if endothelin-1 (ET-1)-induced mesenteric artery constrictions depend on rho kinase (Rock). Mesenteric artery segments were obtained from patients who underwent elective abdominal surgery. Vasodilator concentration-response curves were recorded from ET-1-preconstricted vessels by small vessel myography. Rock expression was investigated by Western blot and the potency of Rock inhibition to blunt ET-1-induced mesenteric artery constriction was tested. Iloprost, PGE1, and papaverine similarly reduced vascular tone to 20% to 30% of ET-1-induced wall tension. In human mesenteric arteries, logEC50 was significantly less for iloprost than for PGE1 or papaverine. Respective logEC50 values were -7.72 ± 0.08 mol/L, -6.58 ± 0.17 mol/L, and -6.73 ± 0.19 mol/L in 150 μm to 300 μm lumen diameter arteries. These vessels were also more sensitive to iloprost than 500 μm to 1,000 μm lumen diameter arteries (logEC50 -7.29 ± 0.07 mol/L). Rock1 and Rock2 were expressed in human mesenteric arteries but Rock inhibition did not significantly affect ET-1-induced vasoconstrictions. Iloprost, PGE1, and papaverine have a similar potency to relax mesenteric arteries. Our data suggest that iloprost but not Rock inhibition may be particularly useful to treat ET-1-induced spasms of distal mesenteric arteries.

    Superior mesenteric arteriovenous fistula is a rare vascular disorder. Endovascular embolization has been widely used to treat this disease. Patients receiving successful fistula embolization generally have good prognoses. We present a man with iatrogenic superior mesenteric arteriovenous fistula who received endovascular embolization. Portal thrombus was detected on postoperative day 2, and the patient eventually died of multiple organ failure on postoperative day 13 despite having received antithrombotic and antiplatelet therapy. We identified portal thrombosis as a serious complication of transcatheter superior mesenteric arteriovenous fistula embolization. Copyright © 2014 Elsevier Inc. All rights reserved.

    We report the use of a spinal cord stimulator (SCS) for non-surgical management of superior mesenteric artery thrombosis. A 59-year-old woman with polycythaemia rubra vera presented with extensive superior mesenteric artery thrombosis not amenable to surgical or endovascular revascularisation. A SCS was implanted for analgesia thereby allowing enteral feeding to be tolerated during the acute period. Four months later the patient developed a focal ischaemic jejunal stricture and underwent resection of a short segment of small bowel with primary anastomosis that healed without complication. Spinal cord stimulation can facilitate non-surgical management of mesenteric ischaemia.

    An adult castrated male cat was evaluated because of a 4 day history of lethargy and partial anorexia. Physical examination revealed abdominal pain with a palpable fluid wave. Cytologic and biochemical analyses of peritoneal effusion were suggestive of septic peritonitis. On surgical exploration of the abdomen, the mesenteric vessels had no palpable pulses and they contained gross thromboses. The intestines were white with no visible peristalsis. Necropsy findings included disseminated, poorly differentiated hemangiosarcoma throughout the abdomen. Mesenteric arterioles contained fibrin thrombi. To the author's knowledge, no previous reports exist of complete mesenteric vascular thrombosis associated with disseminated abdominal visceral hemangiosarcoma in a cat.

    The diagnosis of acute mesenteric ischemia among intensive care unit (ICU) patients continues to be difficult and carries high mortality, and yet, it is essential that it be made expeditiously such that lifesaving operative intervention can be offered. A recent study suggested that computed tomography (CT) scan delays operative intervention. Thus, we hypothesized that diagnostic peritoneal lavage (DPL), a rapidly performed bedside procedure of established high sensitivity, is associated with reduced operative intervention, time to operative intervention, and mortality. We performed a single-institution, retrospective study of 120 patients admitted to an ICU at the University of Pittsburgh Medical Center's Presbyterian Hospital between January 1, 2002, and December 31, 2010, who were diagnosed with acute mesenteric ischemia. We defined a DPL of greater than 500 cells per cubic millimeter as diagnostic of intra-abdominal pathology. CT scan results were categorized as (1) diagnostic of mesenteric ischemia, (2) abnormal, or (3) normal. We performed multivariate logistic regression, adjusting for difference in case mix, to determine whether DPL is associated with the outcomes of mortality and operative intervention. The cohort was severely ill, with a mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score of 21.7 (range, 0-48), and 51 patients (42.5%) died. The distribution of preoperative evaluation is as follows: CT, 67; DPL, 11; both modalities, 18; and no preoperative evaluation, 24. Those undergoing DPL were more severely ill, as evidenced by significantly higher APACHE II scores. By comparison with CT, DPL was associated with a reduced risk for operation intervention (adjusted odds ratio, 0.04; 95% confidence interval, 0.01-0.32; p = 0.002) and mortality (adjusted odds ratio, 0.09; 95% confidence interval, 0.01-0.62; p = 0.02). DPL is associated with reduced operative intervention yet improved survival, when compared with patients evaluated with

    The treatment of advanced desmoid-type fibromatosis (DF) is poorly standardized and primarily based on physician's choice. We assessed systemic treatment preferences for advanced DF among European experts, with the aim to define a control treatment for prospective randomized trials. A structured questionnaire was sent to a group of physicians involved in DF treatment. 54 experts from 14 countries (Europe, Israel) responded. Disease progression and failure of local therapy were typical indications for systemic therapy. Treatment preferences for patients with sporadic DF versus DF associated with Gardner's syndrome were similar. Physicians use at least 5 different classes of drugs (27 agents). The most frequently used compounds were anti-estrogens and non-steroidal anti-inflammatory agents (NSAIDs), in combination or as single agents. The second and third most common systemic approach was chemotherapy based on methotrexate or an anthracycline. Trial activity was limited to 1 country/1 multicentric study. There is an unmet medical need for evidence-based treatments and well-designed studies. Clinical trials with systemic agents should ideally select a homogeneous DF population with advanced, progressive, ideally symptomatic disease and/or functional impairment after failure of wait-and-see and/or local treatments, and should be randomized, with placebo, anti-estrogens, NSAIDs, or physician's choice as comparator. © 2018 S.

    Fetal blood pressure increases during late gestation; however, the underlying vascular mechanisms are unclear. Knowledge of the maturation of resistance arteries is important to identify the mechanisms and vulnerable periods for the development of vascular dysfunction in adulthood. We determined the functional and structural development of fetal sheep mesenteric resistance arteries using wire myography and immunohistochemistry. Media mass and distribution of myosin heavy-chain isoforms showed no changes between 0.7 (100 ± 3 days) and 0.9 (130 ± 3 days) gestation. However, from 0.7 to 0.9 gestation, the resting wall tension increased accompanied by non-receptor-dependent (potassium) and receptor-dependent (noradrenaline; endothelin-1) increases in vasocontraction. Angiotensin II had no contractile effect at both ages. Endothelium-dependent relaxation to acetylcholine and prostaglandin E2 was absent at 0.7 but present at 0.9 gestation. Augmented vascular responsiveness was paralleled by the maturation of sympathetic and sensory vascular innervation. Non-endothelium-dependent relaxation to nitric oxide showed no maturational changes. The expression of vasoregulator receptors/enzymes did not increase between 0.7 and 0.9 gestation. Vascular maturation during late ovine gestation involves an increase in resting wall tension and the vasoconstrictor and vasodilator capacity of the mesenteric resistance arteries. Absence of structural changes in the tunica media and the lack of an increase in vasoregulator receptor/enzyme expression suggest that vasoactive responses are due to the maturation of intracellular pathways at this gestational age. © 2017 S.

    Full Text Available Primary hepatic signet ring cell neuroendocrine tumor (NET is extremely rare, and may show both neuroendocrine and glandular differentiation. Unlike the usual signet ring cells of adenocarcinoma, these cells are characterized by mucin negative, cytokeratin and chromogranin positive intracytoplasmic vacuoles resembling signet ring cells. These tumors are usually well demarcated surgically resectable lesions. To the best of our knowledge, we report the fifth case of primary hepatic signet ring cell NET, with the present case bearing multiple hepatic space occupying lesions and mesenteric metastasis. Due to very few isolated reports, prognosis of NET with signet ring cell morphology is largely unknown. Documentation of this case with review of related literature may enrich the existing knowledge regarding the outcome and management of this rare tumor.

    Mesenteric vein thrombosis is a rare disorder that is often the first manifestation of a systemic condition such as a hypercoagulable state or cancer. In particular, myeloproliferative disorders can present as mesenteric vein thrombosis even in the setting of relatively normal peripheral blood counts. A recent novel mutation in the Janus activated kinase 2 gene involving a gain-of-function substitute of valine to phenylalanine at position 617 (JAK2 V617F) has been discovered to be prevalent in patients with mesenteric vein thrombosis and myeloproliferative disorders. This article reports a patient who presented with mesenteric vein thrombosis and relatively normal peripheral blood counts. He was diagnosed with essential thrombocythemia after he tested positive for the JAK2 V617F mutation. Copyright (c) 2010 Society for Vascular Surgery. Published by Mosby, Inc. All rights reserved.

    Protein S (PS), a vitamin K-dependent glycoprotein, performs an important role in the anticoagulation cascade as a cofactor of protein C. Because of the presence of a pseudogene and two different forms of PS in the plasma, protein S deficiency (PSD) is one of the most difficult thrombophilias to study and a rare blood disorder associated with an increased risk of thrombosis. We describe a unusual case of previously healthy 37-year-old man diagnosed with portal-splenic-mesenteric vein thrombosis secondary to PSD. The patient was admitted to the hospital due to continuous nonspecific abdominal pain and nausea. Abdominal computed tomography revealed acute venous thrombosis from inferior mesenteric vein to left portal vein via splenic vein, and laboratory test revealed decreased PS antigen level and PS functional activity. Conventional polymerase chain reaction and direct DNA sequencing analysis of the PROS1 gene demonstrated duplication of the 166th base in exon 2 resulting in frame-shift mutation (p.Arg56Lysfs*10) which is the first description of the new PROS1 gene mutation to our knowledge. Results from other studies suggest that the inherited PSD due to a PROS1 gene mutation may cause venous thrombosis in a healthy young man without any known predisposing factor.

    To analyze the clinical spectrum of acute mesenteric venous thrombosis (AMVT), to assess the factors affecting the outcome and to determine the optimal management of this disease. We retrospectively reviewed the case records of 20 patients with acute mesenteric venous thrombosis confirmed on CT imaging or on laparotomy over a 23 year period. Patients were divided into two groups according to the duration of symptoms: group I with symptoms for up to 3 days duration and group II with symptoms for more than 3 days. The mean age was 50.55 year, with 15 male and five female patients. In all patients the diagnosis were confirmed on CT imaging preoperatively except two patients when the diagnosis was established on exploratory laparotomy in the period before 1998. There were six patients in group I and 14 in group II. Five patients underwent an operation and one received a non-operative treatment in group I. Three patients underwent laparotomy and 11 received non-operative treatment in group II (P-value 0.01, Fisher's exact test). There were three and one mortality in groups I (n=6) and II (n=14) respectively (P-value 0.061, Fisher's exact test). Most patients received preoperative therapeutic anticoagulation. Two patients in group II who underwent exploratory laparotomy, neither did receive preoperative anticoagulation. Both patients died in the postoperative period. Eighteen patients were investigated for thrombophilia. Eleven patients had one (n=6) or more (n=5) identifiable hypercoagulable state, these included protein S deficiency (n=1), both protein C and S deficiency (n=5), polycythemia (n=2), factor V Leiden deficiency (n=1) and malignancy (n=2). None had antithrombin III deficiency, hyperhomocystine urea and contraceptive pill intake. There were no statistical differences between thrombophilic and non-thrombophilic patients regarding duration of symptoms, indications for laparotomy and 30 days mortality rate.

    The human mesentery is now regarded as contiguous from the duodenojejunal (DJ) to anorectal level. This interpretation prompts re-appraisal of computed tomography (CT) images of the mesentery. A digital model and reference atlas of the mesentery were generated using the full-colour data set of the Visible Human Project (VHP). Seventy one normal abdominal CT images were examined to identify mesenteric regions. CT appearances were correlated with cadaveric and histological appearances at corresponding levels. Ascending, descending and sigmoid mesocolons were identifiable in 75 %, 86 % and 88 % of the CTs, respectively. Flexural contiguity was evident in 66 %, 68 %, 71 % and 80 % for the ileocaecal, hepatic, splenic and rectosigmoid flexures, respectively. A posterior mesocolic boundary corresponding to the anterior renal fascia was evident in 40 % and 54 % of cases on the right and left, respectively. The anterior pararenal space (in front of the boundary) corresponded to the mesocolon. Using the VHP, a mesenteric digital model and reference atlas were developed. This enabled re-appraisal of CT images of the mesentery, in which contiguous flexural and non-flexural mesenteric regions were repeatedly identifiable. The anterior pararenal space corresponded to the mesocolon. (orig.)

    The human mesentery is now regarded as contiguous from the duodenojejunal (DJ) to anorectal level. This interpretation prompts re-appraisal of computed tomography (CT) images of the mesentery. A digital model and reference atlas of the mesentery were generated using the full-colour data set of the Visible Human Project (VHP). Seventy one normal abdominal CT images were examined to identify mesenteric regions. CT appearances were correlated with cadaveric and histological appearances at corresponding levels. Ascending, descending and sigmoid mesocolons were identifiable in 75 %, 86 % and 88 % of the CTs, respectively. Flexural contiguity was evident in 66 %, 68 %, 71 % and 80 % for the ileocaecal, hepatic, splenic and rectosigmoid flexures, respectively. A posterior mesocolic boundary corresponding to the anterior renal fascia was evident in 40 % and 54 % of cases on the right and left, respectively.

    Cavitating mesenteric lymph node syndrome (CMLNS) is an infrequently reported manifestation of unrecognized/longstanding celiac disease and may be associated with enteropathy-associated intestinal T-cell lymphoma and hyposplenism. Unrecognized malignancy and life-threatening infections can pose a significant risk to patients in cases of delayed diagnosis. Fine-needle aspiration of the mesenteric lesions may contribute significantly to the correct diagnosis and can expedite patient management. We report on the cytologic characteristics of enteropathy-associated intestinal T-cell lymphoma first detected in a cyst fluid specimen obtained from a patient with cavitating mesenteric lesions. Image-guided fine-needle aspiration resulted in chylous fluid that contained a lymphoid cell population with neoplastic morphology and abnormal immunophenotype. Further work-up led to the diagnosis of enteropathy-associated intestinal T-cell lymphoma with bone marrow involvement. Cytologic assessment of the cyst fluid is an important part of the diagnostic cascade in patients with CMLNS to exclude clinically occult lymphoma. © 2014 Wiley Periodicals, Inc.

    A protein with high affinity for vitamin D3 and 25-hydroxyvitamin D3 in rat mesenteric lymph has been studied. Mesenteric lymph was collected after duodenal instillation of radiolabeled vitamin D3 and 25-hydroxyvitamin D3. As previously described, approximately 10% of vitamin D3 and 95% of 25-hydroxyvitamin D3 recovered in mesenteric lymph were associated with the alpha-globulin fractions. The radioactive vitamin D3 recovered in the lymph fraction with d greater than 1.006 (free of chylomicrons) coeluted with purified rat serum binding protein for vitamin D and its metabolites (DBP) from an antirat DBP column. The results obtained by immunoblotting after sodium dodecyl sulfate polyacrylamide gel electrophoresis showed that this protein in mesenteric lymph had molecular weight and immunological properties identical with purified serum DBP. Purified serum DBP labeled with 125 I was injected intravenously and mesenteric lymph was collected. results suggesting that DBP may be transferred from blood to mesenteric lymph and that plasma and lymph DBP may have a similar origin

    Objective: The counterclockwise rotation of the SMV on SMA is a normal and non-specific finding, which results in an incomplete swirl formation on CT scans. However, it has a potential to be misinterpreted as ‘midgut volvulus’ resulting in serious clinical implications. The study was done to determine the frequency and degree of counterclockwise rotation of the SMV on SMA on CT in normal otherwise asymptomatic pediatric patients undergoing CT scan. Methods: In this IRB approved study, we retrospectively analyzed abdominal CT scan examinations of 200 consecutive pediatric patients (age range of 11 days to 18 years), which were performed for different clinical indications over a period of 10 months. They were evaluated for the absence or presence and degree of counterclockwise rotation of the mesenteric vessels. Results: Of the 200 patients, 128 (64%) patients showed no clockwise or anticlockwise rotation of mesenteric vessels. Counterclockwise rotation of SMV on SMA was seen in 72 (36%) patients. Further, the degree of rotation of vessels was also calculated, based on the criteria proposed by the authors. Conclusions: The counterclockwise rotation of SMV on SMA gives an appearance of mesenteric whirlpool in otherwise normal mesenteric vessels and can be misinterpreted as midgut volvulus. It is a normal CT appearance and is due to a variation in branching pattern of mesenteric vessels. Awareness of this normal branching pattern of mesenteric vessels is important to avoid an inadvertent laparotomy

    Objective: The purpose of this study was to assess the efficacy of multidetector-row CT (MDCT) for the diagnosis of non-occlusive mesenteric ischemia (NOMI) by analyzing morphology and diameter of superior mesenteric artery (SMA). We assessed whether MDCT was as useful as angiography for the diagnosis of NOMI. Materials and methods: Four patients who were diagnosed with NOMI were retrospectively analyzed. All patients had 8-row MDCT followed by laparotomy. Two of them underwent angiography after MDCT. The morphology and diameter of SMA of these cases was analyzed on multi-planar reconstructed (MPR) images. The mean diameter of SMA of NOMI cases was compared to that of 13 control cases. Results: MPR images of all NOMI cases showed irregular narrowing of the SMA, spasm of the arcades of SMA, and poor demonstration of intramural vessels. MPR images of two patients who had angiography were concordant with their angiograms. The mean diameter of SMA of NOMI patients was 3.4 ± 1.1 mm, which was statistically smaller than that of 13 control patients, 6.0 ± 1.5 mm (P < 0.05, Wilcoxon rank sum tests). Conclusion: Angiography has been recognized essential for the diagnosis of NOMI. This study shows the possibility of MDCT to be an equivalently useful modality compared to angiography for the diagnosis of NOMI by interpreting morphologic appearance and diameter of SMA. Introduction of MDCT in the decision tree of NOMI treatment may bring the benefit of prompt diagnosis and subsequent early and efficient initiation of therapy, which may improve the mortality.

    To determine the activity of radiotherapy in patients with inoperable desmoid-type fibromatosis (DF) a multicenter prospective phase II trial was carried out. Patients with inoperable progressive disease of primary, recurrent or incompletely resected lesions received a dose of 56 Gy in 28 fractions. Follow-up MRI studies were carried out every 3 months for 2 years and thereafter every 6 months. The primary end point was local control rate at 3 years, estimated by a nonparametric method for interval-censored survival data. Secondary end points were objective tumor response, acute and late toxic effect. Forty-four patients (27 F/17 M) were enrolled from 2001 to 2008. Median age was 39.5 years. Main tumor sites included trunk 15 (34.1%) and extremities 27 (61.3%). Median follow-up was 4.8 years. The 3-year local control rate was 81.5% (90% one-sided confidence interval 74% to 100%). Best overall response during the first 3 years was complete response (CR) 6 (13.6%), partial response (PR) 16 (36.4%), stable disease 18 (40.9%), progressive disease 3 (6.8%) and nonassessable 1 (2.3%). Five patients developed new lesions. After 3 years, the response further improved in three patients: (CR 2, PR 1). Acute grade 3 side-effects were limited to skin, mucosal membranes and pain. Late toxic effect consisted of mild edema in 10 patients. Moderate dose radiotherapy is an effective treatment of patients with DF. Response after radiation therapy is slow with continuing regression seen even after 3 years.

    Full Text Available Objective. Acute mesenteric ischemia (AMI is a rare but serious complication after cardiac surgery. The aim of this retrospective study was to evaluate the incidence, outcome, and perioperative risk factors of AMI in the patients undergoing elective cardiac surgery. Methods. From January 2005 to May 2013, all patients who underwent cardiac surgery were screened for participation, and patients with registered gastrointestinal complications were retrospectively reviewed. Univariate analyses were performed. Results. The study included 6013 patients, of which 52 (0.86% patients suffered from AMI, 35 (67% of whom died. The control group (150 patients was randomly chosen from among cases undergoing cardiopulmonary bypass (CPB. Preoperative parameters including age (, renal insufficiency (, peripheral vascular disease (, preoperative inotropic support (, poor left ventricular ejection fraction (, cardiogenic shock (, and preoperative intra-aortic balloon pump (IABP support ( revealed significantly higher levels in the AMI group. Among intra- and postoperative parameters, CPB time (, dialysis (, inotropic support (, prolonged ventilator time (, and IABP support ( appeared significantly higher in the AMI group than the control group. Conclusions. Prompt diagnosis and early treatment should be initiated as early as possible in any patient suspected of AMI, leading to dramatic reduction in the mortality rate.

    Leptin, a protein with a cytokine-like structure, is produced predominantly by adipocytes. It appears to play a key role in immune responses by increasing the secretion of Th1 and pro-inflammatory cytokines. As fat-wrapping is a characteristic feature of Crohn's disease (CD), and as increased leptin levels have been reported in animal models of intestinal inflammation, this study investigated whether mesenteric adipose tissue could be a source of leptin in human inflammatory bowel disease (IBD). To quantify the expression of leptin mRNA in mesenteric adipose tissue of patients with CD or ulcerative colitis (UC). Specimens were obtained from mesenteric white adipose tissue close to healthy and inflammatory small intestine and/or colon in patients with CD or UC and, for controls, from apparently healthy mesentery of patients operated for carcinoma of the right colon. The expression of leptin mRNA was assessed by reverse transcription-competitive polymerase chain reaction. Leptin mRNA levels were significantly higher in mesenteric adipose tissue of CD and UC patients than in controls (P<0.05). In CD and UC, concentrations were not significantly different in mesenteric fat specimens, whether contiguous to macroscopically normal or grossly abnormal intestine. This study provides the first evidence of a novel abnormality of the mesentery of patients with IBD. Overexpression of leptin mRNA in mesenteric adipose tissue may contribute to (a) the inflammatory process, (b) enhancement of mesenteric TNF alpha expression in CD (as recently reported), and/or (c) the anorexia frequently reported during flares of IBD.

    Our aim was to report the multidetector-row computed tomography (MDCT) findings of sclerosing mesenteritis, which is a rare disease characterized by chronic nonspecific inflammation of mesenteric adipose tissue. It has associated diseases, and we explored its prevalence. A total of 2100 patients were evaluated retrospectively for sclerosing mesenteritis between December 2007 and May 2009. Signs and symptoms, associated diseases, laboratory data, surgical histories, and related findings of a misty mesentery, which corresponds to sclerosing mesenteritis on MDCT, were recorded. Misty mesentery findings were seen in 51 (2.43%; 35 men) patients. Their ages ranged between 33 and 78 years (mean 56.2 years). The most frequent complaint of patients was abdominal pain (n=19; 37.2%). The most prominent possible causative and/or associated factors in our study were malignancy (n=9; 17.6%), previous surgery (n=17; 33.3%), smoking (n=20; 39.2%), coronary artery disease (n=9; 17.6%), urolithiasis (n=10; 19.6%), hypertension (n=18; 35.2%), hyperlipidemia (n=13; 25.5%), and diabetes mellitus (n=11; 21.5%). On MDCT, density values in mesenteric fat (-62.8±18.6 Hounsfield unit (HU)) were significantly higher than the values for subcutaneous (-103.9±5.8 HU) and retroperitoneal (-105±6 HU) fatty tissues (both P<0.0001). A partially hyperdense stripe (n=37; 72.6%), well-defined soft tissue nodules (100%), hypodense fatty halo enclosing vessels (n=1; 1.9%), and nodules (n=12; 23.5%) were demonstrated in most of the patients. The diagnosis of sclerosing mesenteritis has increased with the more frequent use of MDCT and the popularization of the Digital Imaging and Communications in Medicine (DICOM) viewer. Defined hallmarks on MDCT can be helpful for differentiating sclerosing mesenteritis from other pathologies. (author)

    Objective: To assess the role of multidetector CT angiography (MDCTA) in the diagnosis of acute mesenteric ischemia (AMI) and to compare the diagnostic utility of axial images with reconstructed images. Materials and methods: In this Institute Review Board approved prospective study, MDCTA was performed on 31 patients who presented with the clinical suspicion of AMI (25M; 6F, age range: 16–73 years). Axial and reconstructed images of each patient were evaluated independently by two radiologists for evidence of bowel wall thickening, abnormal mucosal enhancement, bowel dilatation or obstruction, mesenteric stranding, ascites, solid organ infarcts, pneumatosis intestinalis or porto-mesenteric gas, and mesenteric arterial or venous occlusion. MDCT findings were correlated with the surgical findings and clinical outcome. Patients were later divided into two groups: a study group of patients with proven AMI and a control group of patients with an alternate diagnosis, for the purpose of statistical analysis. Results: AMI was correctly diagnosed in all 16 patients on MDCTA (100% sensitivity and specificity) of whom nine patients underwent surgical exploration. Three patients expired before surgery and the remaining 5 patients were proven based on positive clinical and laboratory findings. Mesenteric arterial occlusion was seen in 7 patients while 5 patients had portomesenteric venous thrombosis. Reconstructed images using minimum intensity projection, volume rendering and multiplanar volume reconstruction were found to perform better for the detection of vascular abnormalities and improved the diagnostic confidence of both radiologists in the evaluation of bowel and mesenteric abnormalities. Conclusion: MDCTA is an effective non-invasive modality for the diagnosis of mesenteric ischemia.

    IntroductionMesenteric bleeding is a rare but potentially life-threatening complication of blunt abdominal trauma. It can induce active hemorrhage and a compressive hematoma leading to bowel ischemia. Emergency laparotomy remains the gold standard treatment. We aimed to study the effectiveness and complications of embolization in patients with post-traumatic mesenteric bleeding.Materials and MethodsThe medical records of 7 consecutive patients with active mesenteric bleeding treated by embolization in a level-one trauma center from 2007 to 2014 were retrospectively reviewed. All patients presented with active mesenteric bleeding on CT scans without major signs of intestinal ischemia. We focused on technical success, clinical success, and the complications of embolization.ResultsSix endovascular procedures were successful in controlling hemorrhage but 1 patient had surgery to stop associated arterial and venous bleeding. One patient suffered from bowel ischemia, a major complication of embolization, which was confirmed by surgery. No acute renal failure was noted after angiography. For 1 patient we performed combined management as the endovascular approach allowed an easier surgical exploration.ConclusionIn mesenteric trauma with active bleeding, embolization is a valuable alternative to surgery and should be considered, taking into account the risk of bowel ischemia.

    Computed tomography angiography (CTA) of the abdomen with multiple detector-row computed tomography (MD-CT) is an effective technique for minimally invasive imaging of the renal arteries and the visceral vasculature. This article reviews the clinical and technical aspects of MD-CT angiography in terms of image acquisition and reconstruction parameters, contrast medium application, and three-dimensional visualization with special attention to renal and mesenteric vascular imaging. Because of its high sensitivity to detect renal artery stenosis on the one hand, and because a normal renal CTA virtually excludes the presence of a significant renal artery stenosis on the other hand, renal CTA plays a useful role in the management of patients with suspected renovascular hypertension. Mesenteric CTA is a useful tool for visualizing normal vascular anatomy and its variants--particularly in the setting of organ transplantation. Vascular pathology, e.g. atherosclerotic disease (abdominal angina), or aneurysms of the visceral arteries are reliably assessed with CTA. Mesenteric CTA is an invaluable adjunct to abdominal CT in the setting of abdominal emergencies, because of its ability to detect the causes of acute intestinal ischemia (superior mesenteric artery embolism or thrombosis, superior mesenteric vein thrombosis). Accurate timing of the CTA acquisition and the subsequent parenchymal phase acquisition relative to the contrast medium transit time is critical to obtain excellent image quality in double-pass abdominal CT acquisitions.

    Full Text Available This study aimed to investigate the effect of mesenteric lymph drainage on the acute kidney injury induced by hemorrhagic shock without resuscitation. Eighteen male Wistar rats were randomly divided into sham, shock, and drainage groups. The hemorrhagic shock model (40 mmHg, 3 h was established in shock and drainage groups; mesenteric lymph drainage was performed from 1 h to 3 h of hypotension in the drainage group. The results showed that renal tissue damage occurred; the levels of urea, creatinine, and trypsin in the plasma as well as intercellular adhesion molecule-1 (ICAM-1, receptor of advanced glycation end-products (RAGE, tumor necrosis factor-α (TNF-α, malondialdehyde (MDA, lactic acid (LA, and 2,3-DPG in the renal tissue were increased in the shock group after 3 h of hypotension. Mesenteric lymph drainage lessened the following: renal tissue damage; urea and trypsin concentrations in the plasma; ICAM-1, RAGE, TNF-α, MDA, and LA levels in the renal tissue. By contrast, mesenteric lymph drainage increased the 2,3-DPG level in the renal tissue. These findings indicated that mesenteric lymph drainage could relieve kidney injury caused by sustained hypotension, and its mechanisms involve the decrease in trypsin activity, suppression of inflammation, alleviation of free radical injury, and improvement of energy metabolism.

    Full Text Available An 83-year-old woman was referred to our emergency department with acute urticaria and sudden shortness of breath approximately 30 min after taking rectal diclofenac potassium for lumbago. After treatment with adrenaline and corticosteroids, the patient became hemodynamically stable and left the hospital on the next day. She attended our hospital 1 week after the onset of anaphylaxis because of repeated postprandial epigastric pain. No abnormal lesions were found in endoscopy. Radiographic selective catheter angiography revealed chronic mesenteric ischemia caused by atherosclerosis and abundant collateral arteries between the celiac trunk, the superior mesenteric artery and the inferior mesenteric artery. Patients with chronic mesenteric ischemia usually present with a clinical syndrome characterized by painful abdominal cramps and colic occurring typically during the postprandial phase. Fear of eating resulted in malnutrition. She was prescribed proton pump inhibitor, digestants, anticholinergic agents, serine protease inhibitors, prokinetics, antiplatelet agents and transdermal nitroglycerin intermittently, but these had no beneficial effects. It was most probable that this patient with chronic atherosclerotic mesenteric ischemia was suffering from functional abdominal pain syndrome induced by anaphylaxis. Since psychiatric disorders were associated with alterations in the processing of visceral sensation, we facilitated the patient’s understanding of functional abdominal pain syndrome with the psychologist. Postprandial abdominal pain gradually faded after administration of these drugs and the patient left the hospital. Developing a satisfactory patient-physician relationship was considered more effective for the management of persistent abdominal pain caused by complicated mechanisms.

    Full Text Available Abstract Background Rats fed high fat (HFD or high sucrose (HSD diets develop increased adiposity as well as impaired vasodilatory responsiveness stemming from oxidative stress. Moreover, HFD rats become hypertensive compared to either control (Chow or HSD fed rats, suggesting elevated vascular tone. We hypothesized that rats with increased adiposity and oxidative stress demonstrate augmented pressure-induced vasoconstriction (i.e. myogenic tone that could account for the hypertensive state. Methods Male Sprague-Dawley rats were fed Chow, HFD or HSD for 6 weeks. The effects of oxidative stress and endogenous nitric oxide on myogenic responses were examined in small mesenteric arteries by exposing the arteries to incremental intraluminal pressure steps in the presence of antioxidants or an inhibitor of nitric oxide synthase, LNNA (100 μM. Results Contrary to the hypothesis, rats fed either HSD or HFD had significantly impaired myogenic responses despite similar vascular morphology and passive diameter responses to increasing pressures. Vascular smooth muscle (VSM calcium levels were normal in HFD arteries suggesting that diminished calcium sensitivity was responsible for the impaired myogenic response. In contrast, VSM calcium levels were reduced in HSD arteries but were increased with pre-exposure of arteries to the antioxidants tiron (10 mM and catalase (1200 U/mL, also resulting in enhanced myogenic tone. These findings show that oxidative stress impairs myogenic tone in arteries from HSD rats by decreasing VSM calcium. Similarly, VSM calcium responses were increased in arteries from HFD rats following treatment with tiron and catalase, but this did not result in improved myogenic tone. Nitric oxide is involved in the impaired myogenic response in HFD, but not HSD, rats since inhibition with LNNA resulted in maximal myogenic responses at lower intraluminal pressures and VSM calcium levels, further implicating reduced calcium sensitivity in

    The caudal mesenteric ganglion (CaMG) is a prevetrebral ganglion which provides innervation to a number of organs in the abdominal and pelvic cavity. The morphology of CaMG and the chemical coding of neurones in this ganglion have been described in humans and many animal species, but data on this topic in the sheep are entirely lacking. This prompted us to undertake a study to determine the localization and morphology of sheep CaMG as well as immunohistochemical properties of its neurons. The study was carried out on 8 adult sheep, weighing from 40 to 60 kg each. The sheep were deeply anaesthetised and transcardially perfused with 4% paraformaldehyde. CaMG-s were exposed and their location was determined. Macroanatomical observations have revealed that the ovine CaMG is located at the level of last two lumbar (L5 or L6) and the first sacral (S1) vertebrae. The ganglion represents an unpaired structure composed of several, sequentially arranged aggregates of neurons. Immunohistochemical investigations revealed that nearly all (99.5%) the neurons were DβH-IR and were richly supplied by VACHT-IR nerve terminals forming "basket-like" structures around the perikarya. VACHT-IR neurones were not determined. Many neurons (55%) contained immunoreactivity to NPY, some of them (10%) stained for Met-ENK and solitary nerve cells were GAL-positive. CGRP-IR nerve fibres were numerous and a large number of them simultaneously expressed immunoreactivity to SP. Single, weakly stained neurones were SP-IR and only very few nerve cells weakly stained for VIP.

    The purpose of this study was to characterize the outcome of attempted endovascular intervention in patients with acute embolic or thrombotic superior mesenteric artery (SMA) occlusion. The records of 21 patients during a 3-year period between 2005 and 2008 were retrieved from the in-hospital registry. The first group included 10 patients (6 women and 4 men; median age 78 years) with acute embolic occlusion of the SMA. The median duration of symptoms from symptom onset to angiography was 30 hours (range 6 to 120). Synchronous emboli (n = 12) occurred in 6 patients. Embolus aspiration was performed in 9 patients, and 7 of these had satisfactory results. Complementary local thrombolysis was successful in 2 of 3 patients. Residual emboli were present at completion angiography in all 7 patients who underwent successful aspiration embolectomy, and bowel resection was necessary in only 1 of these patients. One serious complication occurred because of a long SMA dissection. The in-hospital survival rate was 90% (9 of 10 patients). The second group included 11 patients (10 women and 1 man; median age 68 years) with atherosclerotic acute SMA occlusions. The median time of symptom duration before intervention was 97 hours (range 17 to 384). The brachial, femoral, and SMA routes were used in 6, 7, and 5 patients, respectively. SMA stenting was performed through an antegrade (n = 7) or retrograde (n = 3) approach. Bowel resection was necessary in 4 patients. No major complications occurred. The in-hospital survival rate was 82% (9 of 11 patients). Endovascular therapy of acute SMA occlusion provides a good alternative to open surgery.

    Acute superior mesenteric venous thrombosis is rare. With advance in CT venography, angiography and diagnostic laparoscopy, the incidence of acute superior mesenteric venous thrombosis has increased worldwide with more access to early diagnosis. The use of anticoagulation medication, interventional radiology, and damage control approach has resulted in better clinical outcomes. At present, the new step-up approach for acute superior mesenteric venous thrombosis includes CT venography as the main diagnostic technique, anticoagulation as the cornerstone of therapy, local transcatheter thrombolytic therapy as the key recanalization method, and adjunctive use of arterial spasmolysis and various endovascular manipulation and damage control surgery by intestinal resection plus jejunostomy and ileostomy or open abdomen. This strategy may further improve clinical outcomes. This review will present the most recent advance in this strategy.

    Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors' knowledge, a complete cranial mesenteric arterial obstruction due to verminous arteritis has rarely been described in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.

    Full Text Available Context The serum carcinoembryonic antigen (CEA is an important prognostic factor in colorectal cancer, however the rectum presents different routes of venous drainage, stating that the level of CEA in peripheral and mesenteric rectal tumors may be different, depending on the location of the tumor in the rectal segment. Objective The goal of this study was to evaluate the relationship between the peripheral and mesenteric venous levels of CEA and the association between these levels and the tumour location in the rectums of patients successfully operated on for rectal carcinoma. Methods Thirty-two patients who were surgically treated for rectal carcinoma were divided into patients with tumours located in the upper rectum (n = 11 or lower rectum (n = 21. The CEA values were assessed by electrochemiluminescence immunoassay. Serum and mesenteric CEA levels were associated with the tumour anatomopathological characteristics: location, histological type, cellular differentiation grade, depth of invasion into the rectal wall, angiolymphatic invasion, tumour, node, and metastasis staging; and the CEA index (≤1.0 or ≥1.0 ng /mL. Results Analysis of the serum CEA values using clinical and anatomopathological parameters revealed no significant association with tumour location, histological type, cellular differentiation grade, depth of invasion into the intestinal wall, and tumour, node, and metastasis staging. The mesenteric CEA levels were significantly associated with the tumour location (P = 0.01. The CEA values in the mesenteric venous blood and the presence of angiolymphatic invasion (P = 0.047 were significantly different. A significant relationship was found between the CEA index value and the rectal tumour location (P = 0.0001. Conclusions The CEA levels were higher in the mesenteric vein in tumours located in the upper rectum and in the presence of angiolymphatic invasion. CEA drainage from lower rectum adenocarcinomas preferentially occurs

    We evaluated the usefulness of MRI and compared it with CT for diagnosis of mesenteric lymphoma in a dog. The results in the plain CT, dynamic CT and plain MR (T1WI and T2WI) images suggested that the mass was a large single nodular lesion with abundant blood perfusion. On enhanced MRI(T1WI) , the mass was depicted as a tumor with adhesion to the gut wall. Exploratory laparotomy confirmed the mass was consistent with the findings on enhanced MRI. We think that MRI might be a useful imaging tool for diagnosis of canine mesenteric lymphoma.

    Although acute aortic occlusion (AAO) and acute mesenteric ischemia (AMI) are relatively rare condition, it is very important to know clinical features and managements for these because a delay in diagnosis and appropriate interventions results in high morbidity and mortality. AAO can result from aortic saddle embolus, acute thrombosis of an atherosclerotic aorta, and so on. Superior mesenteric artery embolism and thrombosis are main cause of AMI. The purpose of this article is to review the pathophysiology, clinical presentation, diagnosis, and management of these diseases. The latest information in this article may help readers to promptly make the diagnosis and effectively manage it in a timely manner.

    Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, acquired, life-threatening haematological disorder. It is characterised by complement induced haemolytic anaemia, thrombosis and impaired bone marrow function. Thrombosis most commonly occurs in the hepatic, portal, superior mesenteric and cerebral veins. A22-year female, previously diagnosed with severe aplastic anaemia treated with anti-lymphocyte globulin (ALG) and cyclosporine, had become transfusion independent for more than 10 years. She presented with abdominal pain and vomiting, initially diagnosed with portal and superior mesenteric vein thrombosis. Immunophenotyping by flow cytometry revealed a diagnosis of paroxysmal nocturnal haemoglobinuria type III. She was treated with vitmamin K anatagonist and platelet transfusion.

    To determine the optimal initial treatment modality for acute superior mesenteric vein thrombosis (ASMVT) in patients with circumscribed peritonitis. A retrospective review was made of the Vascular Surgery Department's medical records to identify adult patients (≥ 18 years old) presenting with circumscribed peritonitis and diagnosed with ASMVT by imaging or endoscopic examination. Patients were selected from the time period between October 2009 and October 2012 to assess the overall performance of a new first-line treatment policy implemented in May 2011 for patients with circumscribed peritonitis, which recommends transcatheter thrombolysis with local anticoagulation and endovascular mechanical thrombectomy. Of the 25 patients selected for study inclusion, 12 had undergone emergency surgical exploration (group 1) and 13 had undergone the initial catheter-directed thrombolysis (group 2). Data extracted from each patient's records for statistical analyses included method of diagnosis, symptoms, etiology and risk factors, thrombus location, initial management, morbidity, mortality, duration and total cost of hospitalization (in Renminbi, RMB), secondary operation, total length of bowel resection, duration of and findings in follow-up, and death/survival. The two treatment groups showed similar rates of morbidity, 30-d mortality, and 1-year survival, as well as similar demographic characteristics, etiology or risk factors, computed tomography characteristics, symptoms, findings of blood testing at admission, complications, secondary operations, and follow-up outcomes. In contrast, the patients who received the initial non-operative treatment of transcatheter thrombolysis had significantly shorter durations of admission to symptom elimination (group 1: 18.25 ± 7.69 d vs group 2: 7.23 ± 2.42 d) and hospital stay (43.00 ± 13.77 d vs 20.46 ± 6.59 d), and early enteral or oral nutrition restoration (20.50 ± 5.13 d vs 8.92 ± 1.89 d), as well as significantly less

    Full Text Available Jennifer R Cook, Karen E Russell, Kristin B Eden, Aline Rodrigues-HoffmannDepartment of Veterinary Pathobiology, College of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, TX, USAAbstract: Although cryptococcosis is usually associated with respiratory and neurologic signs in domestic species (such as sneeze, cough, nasal discharge, seizures, ataxia, clinical manifestations of the disease may be more subtle and nonspecific. A 3-year-old male castrated Boxer dog presented with a history of chronic vomiting, diarrhea, weight loss, and lethargy. At no time had respiratory or neurologic signs been noted by the owners or the primary care veterinarian. Palpation of an abdominal mass revealed an atypical lesion location: a large (16 × 9 × 7 cm mass at the root of the mesentery. Diagnosis was achieved through cytology of this mass and a positive serologic Cryptococcus capsular antigen titer; polymerase chain reaction was utilized for speciation of the abdominal isolate as Cryptococcus neoformans variety grubii. The animal was euthanized due to poor prognosis. After necropsy and histopathologic analysis, the mesenteric mass and associated lymph nodes were identified as large fungal granulomas. This is a rare manifestation of cryptococcosis, involving several visceral organs, with no remaining evidence of the route of entry of the organism. As prompt diagnosis of mycotic illness is paramount to successful management, this case indicates that cryptococcal infection should be considered as a differential diagnosis in dogs with gastrointestinal signs and lymphadenopathy. The protean nature of cryptococcosis is discussed within the context of a brief review of emerging and unresolved issues in pathogenesis.Keywords: Cryptococcus gattii, granuloma, lymphadenitis

    Full Text Available Colonic complications of severe acute pancreatitis occur rarely. Although there have been several theories on how pancreatic pseudocysts rupture into the colon, the exact pathogenesis remains unknown. We report an unusual case of pseudocysts complicating severe acute pancreatitis presenting with colonic perforation in a 71-year-old man with a history of chronic mesenteric ischemia. Pressure effects from a giant pseudocyst and intravascular volume depletion with acute insult on chronic mesenteric ischemia are highlighted as possible etiologic factors.

    Purpose: Mesenteric panniculitis (MP) is an underdiagnosed inflammatory condition of mesenteric adipose tissue. Prior studies suggested an association of MP with malignancy. To reassess this hypothesis, we performed the first matched case–control study comparing prevalence of malignancy and other disease in patients with and without MP. Material and methods: With a keyword search we identified CT examinations of MP patients between 2010 and 2012. Each MP patient was matched with two control patients for age, gender, abdominal diameter and CT protocol. Manifestation and extent of mesenteric panniculitis was classified independently by two investigators according to established criteria. Concomitant disease, laboratory parameters and follow up CTs were recorded and analyzed for all patients. Results: 77 of 13485 CT patients were diagnosed with MP (prevalence 0.58%). 50.6% of MP patients suffered from malignancy vs. 60.2% in the control group (p = 0.157). Over up to 4 years of follow up in 35 of these 77 MP patients no association between development of MP and the course of tumor diseases could be identified. There was also no significant difference in the rate of frequent concomitant diseases such as hypertension, diabetes or previous surgery between the two groups. Conclusion: In this first case–control-study we could show that, contrary to previous reports, mesenteric panniculitis is neither paraneoplastic nor is it associated with other diseases.

    An 8-year-old male red kangaroo (Macropus rufus) was evaluated with a 2-week history of vomiting and anorexia. Four days prior, the patient became refractory to medical management. The kangaroo was admitted for diagnostic testing and treatment including whole body CT, blood work, and emergency laparotomy. CT findings of a severely enlarged stomach, splenic displacement, and a whirl sign were indicative of mesenteric volvulus with gastric dilatation-volvulus (GDV). Contrast enhancement of abdominal viscera suggested intact arterial blood supply; however, compression of the caudal vena cava and portal vein indicated venous obstruction. Results of preoperative blood work suggested biliary stasis without evidence of inflammation. Additionally, a tooth root abscess was diagnosed on the basis of results of CT. Exploratory laparotomy confirmed the diagnosis of mesenteric volvulus and GDV. The volvuli were corrected by clockwise derotation, and a gastropexy was performed. Tissue samples were obtained from the spleen and liver for evaluation. The kangaroo recovered from surgery, and the abscessed tooth was extracted 6 days later. Eight days after initial evaluation, the kangaroo was discharged. In the present report, the CT whirl sign was used to diagnose volvulus of the abdominal viscera, which suggests that this diagnostic indicator has utility in veterinary patients. Mesenteric volvulus with GDV was successfully treated in a nondomestic species. The tooth root abscess, a common condition in macropods, may explain the historic episodes of anorexia reported by the owner and may have contributed to the development of mesenteric volvulus and GDV in this kangaroo.

    We hypothesised that lower mesenteric near-infrared spectroscopy values would be associated with a greater incidence of gastrointestinal complications in children weighing infrared spectroscopy, central venous oxygen saturation, and arterial blood gases for 48 hours post-operatively. Enteral feeding intake, gastrointestinal complications, and markers of organ dysfunction were monitored for 7 days. A total of 50 children, with median age of 16.7 (3.2-31.6) weeks, were studied. On admission, the average mesenteric near-infrared spectroscopy value was 71±18%, and the systemic oxygen saturation was 93±7.5%. Lower admission mesenteric near-infrared spectroscopy correlated with longer time to establish enteral feeds (r=-0.58, pinfrared spectroscopy (58±18% versus 73±17%, p=0.01) and higher mesenteric arteriovenous difference of oxygen at admission [39 (23-47) % versus 19 (4-27) %, p=0.02]. Based on multiple logistic regression, admission mesenteric near-infrared spectroscopy was independently associated with gastrointestinal complications (Odds ratio, 0.95; 95% confidence interval, 0.93-0.97; p=0.03). Admission mesenteric near-infrared spectroscopy showed an area under the receiver operating characteristic curve of 0.76 to identify children who developed gastrointestinal complications, with a suggested cut-off value of 72% (78% sensitivity, 68% specificity). In this pilot study, we conclude that admission mesenteric near-infrared spectroscopy is associated with gastrointestinal complications and enteral feeding tolerance in children after cardiac surgery.

    Objective: To evaluate the clinical value of percutaneous AngioJet thrombectomy in treatment of acute symptomatic portal and superior mesenteric venous thrombosis venous thrombosis (PVMVT) . Method: From January 2014 to January 2016, a total of 8 patients in Nanjing First Hospital with PVMVT verified by color Doppler ultrasound and computed tomographic angiography (CTA) were analyzed retrospectively. Under ultrasound guidance , the branch of the right portal vein(PV) was punctured with a micropuncture set and a 4-F infusion catheter was advanced to the superior mesenteric vein(SMV). The venogram demonstrated the thrombosis in the PV/SMV and a 6-F AngioJet Xpeeedior catheter was advanced over the guidewire and positioned in the distal SMV. Percutaneous thrombectomy was performed after a mixture of 250 000 U of urokinase in 100 ml of normal saline for mechanical pulse spray of thrombus in all patients for approximately 15 minutes. 2 patients underwent PTA and stent implantation after the thrombectomy procedure, 1 of them and the others 6 patients received continuous transcatheter infusion of urokinase (500 000 U/d) for 24 or 48 hours until the thrombosis was completely dissolved confirmed by angiography at 24 and 48 hours.After procedure and the thrombolytic therapy was discontinued, removal of the infusion catheter and the sheath from the liver, the transhepatic tract was embolized with coils or gelfoam to reduce the risk of bleeding. The patency rate of PV /SMV was assessed by CTA at 1 and 6 months after the procedure. Patients were discharged with oral anticoagulation regimen for at least 6 months.The following criteria were used in evaluation of thrombolysis: grade Ⅰ90% thrombus removal. Results: All 8 patients with PVMVT were treated by AngioJet thrombectomy. Angiography after the thrombectomy procedure showed complete thrombus removal (>90%) was in 3 cases, substantial thrombus removal (50%~90%) in 5 cases. Grade Ⅲ (complete) thrombolysis was achieved in 7

Ang II, Ang I, and TDP elicited a dose-dependent vasoconstrictor effect in both vascular preparations that was completely blocked by the Ang II receptor antagonist saralasin (50 nM. The angiotensin converting enzyme (ACE inhibitor captopril (36 µM completely inhibited the vasoconstrictor effect elicited by Ang I and TDP in aortic rings without affecting that of Ang II. In contrast, captopril (36 µM significantly reduced (80-90% the response to bolus injection of Ang I, without affecting those to Ang II and TDP in mesenteric arteries. Mechanical removal of the endothelium greatly potentiated (70-95% the vasoconstrictor response to Ang II, Ang I, and TDP in aortic rings while these responses were unaffected by the removal of the endothelium of mesenteric arteries with sodium deoxycholate infusion. In addition, endothelium disruption did not change the pattern of response elicited by these peptides in the presence of captopril. These findings indicate that the endothelium may not be essential for Ang II formation in rat mesenteric arteries and aorta, but it may modulate the response to Ang II. Although Ang II formation from Ang I is essentially dependent on ACE in both vessels, our results suggest the existence of an alternative pathway in the mesenteric arterial bed that may play an important role in Ang II generation from TDP in resistance but not in large vessels during ACE inhibition

    Mesenteric vein thrombosis (MVT) is a rare and frequently underdiagnosed complication of Crohn's disease (CD). This study describes the clinical and radiological characteristics of CD /patients with superior mesenteric vein thrombosis (MVT) diagnosed by CT/MRI. The database of Crohn's disease patients treated in Sheba Medical Center between 2005-2010 was searched for MVT diagnosis. Imaging studies of identified patients were retrieved and reviewed by an experienced abdominal radiologist. MVT was defined by superior mesenteric vein obliteration and/or thrombus in the vessel lumen on abdominal imaging. The clinical and radiologic data of these patients were collected from the medical records. MVT was demonstrated in 6/460 CD patients. Five patients had stricturing disease, and one patient had a combined fistulizing and stricturing disease phenotype. All patients had small bowel disease, but 3/6 also had colonic involvement. No patient had a prior thromboembolic history or demonstrable hypercoagulability. One patient had an acute SMV thrombus demonstrable on CT scanning, the remaining patients showed an obliteration of superior mesenteric vein. Two patients received anticoagulation upon diagnosis of thrombosis. No subsequent thromboembolic events were recorded. The incidence of mesenteric vein thrombosis is likely to be underestimated in patients with Crohn's disease. Both CT and MRI imaging demonstrate the extent of enteric disease and coincident SMV thrombosis. In our cohort, thrombosis was associated with stricturing disease of the small bowel. The clinical impact of SMV thrombosis and whether anticoagulation is mandatory for all of these patients remains to be determined. Copyright © 2011 European Crohn's and Colitis Organisation.

    Full Text Available Background/Aims: Copper is an essential trace element for normal cellular function and contributes to critical physiological or pathological processes. The aim of the study was to investigate the effects of copper on vascular tone of rat mesenteric artery and compare the effects of copper on noradrenaline (NA and high K+ induced vasoconstriction. Methods: The rat mesenteric arteries were isolated and the vessel tone was measured by using multi wire myograph system in vitro. Blood pressure of carotid artery in rabbits was measured by using physiological data acquisition and analysis system in vivo. Results: Copper dose-dependently blunted NA-induced vasoconstriction of rat mesenteric artery. Copper-induced vasorelaxation was inhibited when the vessels were pretreated with NG-nitro-L-arginine methyl ester (L-NAME. Copper did not blunt high K+-induced vasoconstriction. Copper preincubation inhibited NA-evoked vasoconstriction and the inhibition was not affected by the presence of L-NAME. Copper preincubation showed no effect on high K+-evoked vasoconstriction. Copper chelator diethyldithiocarbamate trihydrate (DTC antagonized the vasoactivity induced by copper in rat mesenteric artery. In vivo experiments showed that copper injection (iv significantly decreased blood pressure of rabbits and NA or DTC injection (iv did not rescue the copper-induced hypotension and animal death. Conclusion: Copper blunted NA but not high K+-induced vasoconstriction of rat mesenteric artery. The acute effect of copper on NA-induced vasoconstriction was depended on nitric oxide (NO, but the effect of copper pretreatment on NA-induced vasoconstriction was independed on NO, suggesting that copper affected NA-induced vasoconstriction by two distinct mechanisms.

    Acute mesenteric ischemia is a potentially fatal vascular emergency with mortality rates ranging between 60% and 80%. Several studies have extensively examined the hemodynamic and metabolic effects of superior mesenteric artery occlusion. On the other hand, the cardiocirculatory derangement and the tissue damage induced by intestinal outflow obstruction have not been investigated systematically. For these reasons we decided to assess the initial impact of venous mesenteric occlusion on intestinal blood flow distribution, and correlate these findings with other systemic and regional perfusion markers. Fourteen mongrel dogs were subjected to 45 min of superior mesenteric artery (SMAO) or vein occlusion (SMVO), and observed for 120 min after reperfusion. Systemic hemodynamics were evaluated using Swan-Ganz and arterial catheters. Regional blood flow (ultrasonic flow probes), intestinal O(2)-derived variables, and mesenteric-arterial and tonometric-arterial pCO(2) gradients (D(mv-a)pCO(2) and D(t-a)pCO(2)) were also calculated. SMVO was associated with hypotension and low cardiac output. A significant increase in the regional pCO(2) gradients was also observed in both groups during the ischemic period. After reperfusion, a progressive reduction in D(mv-a)pCO(2) occurred in the SMVO group; however, no improvement in D(t-a)pCO(2) was observed. The histopathologic injury scores were 2.7 +/- 0.5 and 4.8 +/- 0.2 for SMAO and SMVO, respectively. SMV occlusion promoted early and significant hemodynamic and metabolic derangement at systemic and regional levels. Additionally, systemic pCO(2) gradient is not a reliable parameter to evaluate the local intestinal oxygenation. Finally, the D(t-a)pCO(2) correlates with histologic changes during intestinal congestion or ischemia. However, minor histologic changes cannot be detected using this methodology.

    Emergency pancreatico-duodenectomy(EPD) is a very rare procedure and few reports are present in medical literature. It is an uncommon approach, usually used for emergency surgical treatment of abdominal trauma that involves the head of the pancreas or the duodenum, but it is also a surgical tool for the treatment of ruptured aneurysms, bleeding pseudocysts, duodenal perforations, uncontrollable hemorrhage from ulcers and tumors, severe infectious complications of acute pancreatitis or endoscopic retrograde cholangiopancreatography related complications (1,2). It is rarely used as the first line of treatment in case of acute bleeding from arterial pseudoaneurysm of the cephalad region of the pancreas. We present the case of a bleeding pseudoaneurysm of the cefalic region of the pancreas in a young patient with previously undiagnosed chronic pancreatitis and with suspicion of a malignant process located in the head of the pancreas. We performed a pancreatico-duodenectomy with resection of superior mesenteric and portal vein with reconstruction using Gore-Tex vascular graft due to probable venous abutment. Postoperative course was without any major complications, only minor grad-I pancreatic fistula was present. We determine that EPD is a useful tool in the treatment of such cases. It can be used as a first line of treatment or secondary to endovascular stenting or embolization. Celsius.

    The purpose of this investigation was to assess the feasibility and effectiveness of transradial approach for transcatheter superior mesenteric artery (SMA) urokinase infusion therapy in patients with acute extensive portal and superior mesenteric venous thrombosis. During a period of 7 years, 16 patients with acute extensive thrombosis of the portal (PV) and superior mesenteric veins (SMV) were treated by transcatheter selective SMA urokinase infusion therapy by way of the radial artery. The mean age of the patients was 39.5 years. Through the radial sheath, a 5F Cobra catheter was inserted into the SMA, and continuous infusion of urokinase was performed for 5-11 days (7.1 ± 2.5 days). Adequate anticoagulation was given during treatment, throughout hospitalization, and after discharge. Technical success was achieved in all 16 patients. Substantial clinical improvement was seen in these 16 patients after the procedure. Minor complications at the radial puncture site were observed in 5 patients, but trans-SMA infusion therapy was not interrupted. Follow-up computed tomography scan before discharge demonstrated nearly complete disappearance of PV-SMV thrombosis in 9 patients and partial recanalization of PV-SMV thrombosis in 7 patients. The 16 patients were discharged 9-19 days (12 ± 6.0 days) after admission. Mean duration of follow-up after hospital discharge was 44 ± 18.5 months, and no recurrent episodes of PV-SMV thrombosis developed during that time period. Transradial approach for transcatheter selective SMA urokinase infusion therapy in addition to anticoagulation is a safe and effective therapy for the management of patients with acute extensive PV-SMV thrombosis.

    Full Text Available Introduction.Acute mesenteric ischemia is a surgical emergency that entails complex, multi-modal management, but its epidemiology and outcomes remain poorly defined. The aim of this study was to perform a population analysis of the contemporary incidence and outcomes of mesenteric ischemia.Methods.This was a retrospective analysis of acute mesenteric ischemia in the state of Maryland during 2009 – 2013 using a comprehensive statewide hospital admission database. Demographics, illness severity, comorbidities, and outcomes were studied. The primary outcome was inpatient mortality. Survivors and non-survivors were compared using univariate analyses, and multivariable logistic regression analysis was performed to evaluate risk factors for mortality.Results.During the 5-year study period, there were 3,157,499 adult hospital admissions in Maryland. 2,255 patients (0.07% had acute mesenteric ischemia, yielding an annual admission rate of 10/100,000. Increasing age, hypercoagulability, cardiac dysrhythmia, renal insufficiency, increasing illness severity, and tertiary hospital admission were associated with development of mesenteric ischemia. Inpatient mortality was high (24%. After multivariate analysis, independent risk factors for death were age > 65 years, critical illness severity, mechanical ventilation, tertiary hospital admission, hypercoagulability, renal insufficiency, and dysrhythmia.Conclusions.Acute mesenteric ischemia occurs in approximately 1/1000 admissions in Maryland. Patients with mesenteric ischemia have significant illness severity, substantial rates of organ dysfunction, and high mortality. Patients with chronic comorbidities and acute organ dysfunction are at increased risk of death, and recognition of these risk factors may enable prevention or earlier control of mesenteric ischemia in high-risk patients.

    A 6-year-old Labrador retriever dog was presented for acute abdominal pain. A tentative diagnosis of mesenteric thrombosis was established antemortem. The dog was treated with supportive care and anti-coagulation but was ultimately euthanized due to disease-related complications. Necropsy examination confirmed an acute mesenteric thrombus along with widespread thromboembolic disease. Potential causes were protein-losing nephropathy, hepatopathy, and/or corticosteroid administration.

    Venous thromboembolism is the most common postoperative medical complication after bariatric surgery. Mortality associated with thromboembolic processes can reach up to 50%-75%. The aim of this study was to determine the incidence of deep vein thrombosis (DVT) and portal-splenic-mesenteric vein thrombosis (PSMVT) in our population undergoing laparoscopic sleeve gastrectomy (LSG) as the bariatric technique, with an anti-thromboembolic dosage scheme of 0.5 mg/kg/day 12 hours preoperatively and maintained during 30 days postoperatively. A prospective observational study was performed, including 100 consecutive patients undergoing LSG between October 2007 and September 2013. To determine the incidence of DVT and PSMVT, all patients undergo contrast-enhanced abdominal computed tomography (CT) and Doppler ultrasonography (US) of both lower limbs on the third postoperative month, whether they were asymptomatic or symptomatic. Contrast-enhanced CT showed 1 case of PSMVT (1%). Two patients presented DVT in the right leg (2%). All the cases were asymptomatic. The incidence of PSMVT and DVT after LSG with a prophylactic low-molecular-weight heparin dose of 0.5 mg/kg/day and maintained during 30 days postoperatively is 1% and 2%, respectively. According to these results, a postoperative screening with Doppler US and/or contrast-enhanced CT seems to be unnecessary.

    Full Text Available Objective To investigate superior mesenteric artery flow measurement by Doppler ultrasonography as a means of characterizing inflammatory activity in Crohn's disease. Materials and Methods Forty patients were examined and divided into two groups – disease activity and remission – according to their Crohn's disease activity index score. Mean superior mesenteric artery flow volume was calculated for each group and correlated with Crohn's disease activity index score. Results The mean superior mesenteric artery flow volume was significantly greater in the patients with active disease (626 ml/min ± 236 × 376 ml/min ± 190; p = 0.001. As a cut off corresponding to 500 ml/min was utilized, the superior mesenteric artery flow volume demonstrated sensitivity of 83% and specificity of 82% for the diagnosis of Crohn's disease activity. Conclusion The present results suggest that patients with active Crohn's disease have increased superior mesenteric artery flow volume as compared with patients in remission. Superior mesenteric artery flow measurement had a good performance in the assessment of disease activity in this study sample.

    In previous studies we reported an altered prostanoid (PR) release-pattern in mesenteric vessels in fructose (F)-overloaded rats, an experimental model of insulin resistance and hypertension. Dehydroepiandrosterone (DHEA) and its precursor Dehydroepiandrosterone sulfate (DHEA-S) are the most abundant circulating steroid hormones produced by the adrenal and recent studies in both cells and animals suggest that DHEA may have acute non-genomic actions that mimic both metabolic and vascular actions of insulin. This study was to analyze in F-overloaded rats, the effects of DHEA treatment on arterial blood pressure and the PR production in mesenteric vessels and aorta. Male 6 week-old Sprague-Dawley rats were randomly divided in four groups: a control group (C), a DHEA (30 mg/kg/sc/48 h)-treated group (D), a fructose (10% w/v in drinking water)-fed group (F), and both treatments simultaneously group (FD). The systolic blood pressure (SBP) was measured by tail cuff method and glycemia and triglyderidemia were measured by enzymatic assays. The mesenteric beds of all groups were dissected, and incubated in Krebs solution. The PR released were measured by HPLC. F overload increased SBP and triglyceridemia and decreased the mesenteric vasodilatory PR release. DHEA treatment prevented the increment in SBP and triglyceridemia and decreased vasoconstrictor PR in F-treated rats. DHEA normalize the PGI(2)/TX ratio, diminished in F-overloaded rats, through the decrease in thromboxane (TX) production and this could be one of the mechanisms by which DHEA prevented the slight hypertension in F-animals.

    Splanchnic artery aneurysms are very rare in children. We report a 10-year-old girl with a large atraumatic ruptured superior mesenteric artery aneurysm that was considered inoperable. She was ultimately treated with two percutaneous US-guided thrombin injections, which led to complete occlusion of the aneurysm. The aetiology of the aneurysm remained unclear, but a family history was suggestive of a congenital connective tissue disease such as Ehlers-Danlos syndrome subtype IV. (orig.)

    Xe-133 uptake in patients with fatty livers is described and compared with uptake and retention in lungs, blood and mesenteric fat and with normal hepatic uptake. In the absence of obstructive lung disease or excessive obesity, Xe-133 uptake and retention is a valuable means of screening patients for the presence of fatty liver. Although non-specific for the etiology of fatty liver, the test is an effective and non-invasive method of detection which merits further application. (author)

    In arterioles, aldosterone counteracts the rapid dilatation (recovery) following depolarization-induced contraction. The hypothesis was tested that this effect of aldosterone depends on cyclooxygenase (COX)-derived products and/or nitric oxide (NO) synthase (NOS) inhibition. Recovery of the response to high K(+) was observed in mesenteric arteries of wild-type and COX-2(-/-) mice but it was significantly diminished in preparations from endothelial NOS (eNOS)(-/-) mice. Aldosterone pretreatment inhibited recovery from wild-type and COX-2(-/-) mice. The NO donor sodium nitroprusside (SNP) restored recovery in arteries from eNOS(-/-) mice, and this was inhibited by aldosterone. Actinomycin-D abolished the effect of aldosterone, indicating a genomic effect. The effect was blocked by indomethacin and by the COX-1 inhibitor valeryl salicylate but not by NS-398 (10(-6) mol/l) or the TP-receptor antagonist S18886 (10(-7) mol/l). The effect of aldosterone on recovery in arteries from wild-type mice and the SNP-mediated dilatation in arteries from eNOS(-/-) mice was inhibited by the histamine H2 receptor antagonist cimetidine. RT-PCR showed expression of mast cell markers in mouse mesenteric arteries. The adventitia displayed granular cells positive for toluidine blue vital stain. Confocal microscopy of live mast cells showed loss of quinacrine fluorescence and swelling after aldosterone treatment, indicating degranulation. RT-PCR showed expression of mineralocorticoid receptors in mesenteric arteries and in isolated mast cells. These findings suggest that aldosterone inhibits recovery by stimulation of histamine release from mast cells along mesenteric arteries. The resulting activation of H2 receptors decreases the sensitivity to NO of vascular smooth muscle cells. Aldosterone may chronically affect vascular function through paracrine release of histamine.

    Objective: To discuss the safety and feasibility of percutaneous aspiration thrombectomy in treating acute mesenteric arterial embolism. Methods: Acute superior mesenteric arterial embolism model was established in 12 hybrid dogs through injection of autologous blood clot via an arterial sheath. According to the removal time of the embolus (2, 4 and 6 hours), the experimental dogs were randomly divided into three groups with 4 dogs in each group. Percutaneous aspiration thrombectomy by using an 8F arterial sheath was carried out at 2, 4 and 6 hours after embolization procedure for the dogs in 2, 4 and 6 hour groups respectively. The results were analyzed. Results: Percutaneous aspiration of the blood bolt with an 8F arterial sheath was successfully accomplished in all experimental dogs of the three groups. The technical success rate was 100%. The average time for the performance of thrombectomy was (2.48±0.47) min, and the average collected volume of the blood was (41.0±4.2) ml. Angiography performed after aspiration revealed that the main stem of the superior mesenteric artery was reopened in all dogs of each group, and residual embolus was seen in a small number of second vascular branches (less than 4 vessels and not adjacent to each other). No serious complications, such as vascular injuries or intestinal bleeding, occurred during and after the aspiration procedures. Conclusion: For the treatment of acute superior mesenteric artery embolism, percutaneous aspiration thrombectomy with an 8F arterial sheath is safe, effective, economical and technically simple.

    Full Text Available Right portal vein embolization is often performed to prevent liver insufficiency after major hepatic resection. The procedure usually involves direct puncture of the portal vein, which requires hepatic hilum manipulation, and may be associated with liver injury, pneumothorax, and hemoperitoneum. This report describes a technique of laparoscopic insertion of a sheath into the inferior mesenteric vein followed by right portal vein embolization.

    In this study, we evaluated if increase in utilization of endovascular surgery has affected in-hospital mortality rates among patients with acute mesenteric ischemia. The National Inpatient Sample (2003-2011) was queried for acute mesenteric ischemia using ICD-9 code for acute mesenteric ischemia (557.1). This cohort was divided into patients treated with open vascular surgery (open vascular group) and by endovascular therapies (endovascular group) based on the ICD-9CM procedure codes. Multivariable logistic regression was used to determine temporal trend for mortality while adjusting for confounding variables. There was 1.45-fold increase in utilization of endovascular techniques in this study. In-hospital mortality rate, total median charges and length of stay were significantly lower among the endovascular group than the open vascular group despite having significantly higher Elixhauser comorbidities index (3 ± 0.1 vs. 2.7 ± 0.1, p = .003). Over the course of the study period, there was no change in the overall mortality rate despite higher endovascular utilization. Factors associated with increased mortality included age, open surgical repair (Odds ratio: 1.45, 95% Confidence Interval: 1.10-1.91, p = .016) and bowel resection Odds ratio: 2.88, 95% Confidence Interval: 2.01-4.12). The mortality rate for acute mesenteric ischemia remains unchanged throughout this contemporary study. Open surgical intervention, bowel resection and age were associated with increased mortality.

    The presence and properties of voltage-gated Na+ channels in mesenteric artery smooth muscle cells (SMCs) were studied using whole cell patch-clamp recording. SMCs from mouse and rat mesenteric arteries were enzymatically dissociated using two dissociation protocols with different enzyme combinations. Na+ and Ca2+ channel currents were present in myocytes isolated with collagenase and elastase. In contrast, Na+ currents were not detected, but Ca2+ currents were present in cells isolated with papain and collagenase. Ca2+ currents were blocked by nifedipine. The Na+ current was insensitive to nifedipine, sensitive to changes in the extracellular Na+ concentration, and blocked by tetrodotoxin with an IC50 at 4.3 nM. The Na+ conductance was half maximally activated at -16 mV, and steady-state inactivation was half-maximal at -53 mV. These values are similar to those reported in various SMC types. In the presence of 1 microM batrachotoxin, the Na+ conductance-voltage relationship was shifted by 27 mV in the hyperpolarizing direction, inactivation was almost completely eliminated, and the deactivation rate was decreased. The present study indicates that TTX-sensitive, voltage-gated Na+ channels are present in SMCs from the rat and mouse mesenteric artery. The presence of these channels in freshly isolated SMC depends critically on the enzymatic dissociation conditions. This could resolve controversy about the presence of Na+ channels in arterial smooth muscle.

In arterioles gap junctions appear to be important for conduction of vasomotor responses along the vessel. Studies of the expression pattern of connexin isoforms...... in the microcirculation are sparse. We investigated the expression of the three major vascular connexins in mesenteric arterioles (diameter micro m) from male Sprague-Dawley rats, since conducted vasomotor responses have been described in these vessels. The findings were compared with those obtained from upstream...... small resistance arteries. Indirect immunofluorescence techniques were used on whole mounts of mesenteric arterioles and on frozen sections of resistance arteries (diameter approximately 300 micro m). Mesenteric arterioles expressed Cx40 and Cx43 in the endothelial layer, and Cx37 was found in most...

    This study was aimed to investigate the cross-sectional shape of mesenteric arterioles at branching, using confocal laser microscopy. Wistar rats (8 weeks, male) were anesthetized with thiobutabarbital sodium. Blood flow and microvascular network in the mesentery were observed using video microscopy. The rat intestine with mesentery was extracted and the intestinal vasculature was perfused with Krebs-Ringer and then fixed with paraformaldehyde under a static pressure of 100mmHg. A section of mesentery was isolated from the intestine, and spread up to the in vivo geometry based on the intravital microscopic observation. The mesentery section was stained with tetramethyl rhodamine isothiocyanate (TRITC)-phalloidin. The samples were observed under a confocal laser microscope. The cross-sectional image was re-sliced to measure the cross-sectional area and major/minor axes of the best fitting ellipse. The aspect ratio was defined in terms of the minor/major diameter ratio. The extended focus image of mesenteric arterioles showed that the cross-sectional shape was not circular but elliptic-like. The cross-sectional area of the parent vessel decreased from proximal to distal positions. The mean aspect ratio of the parent vessel was approximately 0.5, while that of the branching vessel was approximately 0.8. The flattened shape and variation of the cross-sectional area of arterioles requires some correction of in vivo data of the two-dimensional mesenteric microvasculature obtained using intravital microscopy.

    We evaluated the technique of intraperitoneal use of xenon Xe 133, previously described for the diagnosis of early intestinal strangulation obstruction in rats and dogs, for the recognition of acute mesenteric vascular occlusion in these animals. 133 Xe was injected intraperitoneally into five groups of six rats: control, sham operation, superior mesenteric artery (SMA) ligation, superior mesenteric vein ligation, and portal vein ligation. Residual gamma-activity was monitored by external counting and camera imaging. At 30 minutes after injection, the activity was significantly higher in the rats from the three groups with vascular ligation than in the control and sham operation animals (P less than 0.001). gamma-Camera images reflected these findings, with positive images only in the rats that underwent vascular ligation. ''Blinded'' readings of the 30 sets of scans confirmed the diagnostic accuracy of the images. Results were essentially the same in a second series of experiments in eight control dogs and six dogs with balloon occlusion of the SMA. Concentrations of isotope in ischemic intestine ranged from 10(3) to 10(5) times the levels in adjacent normal bowel. These levels and the positive images appeared early, prior to the development of tissue necrosis. The intraperitoneal use of 133 Xe therefore continues to show promise for the recognition of patients with early intestinal ischemia

    The purpose of this study was to investigate the vasoactivity of two inhibitors of potassium ion (K(+) ) channels, a potential antiarrhythmic compound, AVE 0118, and 4-aminopyridine (4-AP). Basal and stimulated tones of rat small mesenteric arteries as well as the possible involvement of KV 1.5 ion channel in the mechanism of vascular effect induced by the compounds were analysed. The standard organ bath technique for vascular tone and immunohistochemistry for the localization of ion channels in the arterial tissue were performed. Third- or fourth-order branch of arterial segments was mounted in myographs for recording the isometric tension. AVE 0118 (10(-5) M) and 4-AP (10(-5) M) modulated neither the basal tone nor the contraction induced by noradrenaline but increased the contraction evoked by electrical field stimulation, sensitive to the block of alpha-1 adrenergic receptors. KV 1.5 ion channel-specific immunostaining demonstrated the presence of immunoreactive nerves, and Schwann-cell-specific (S100) immunostaining confirmed the presence of myelin sheath in rat small mesenteric arteries. The study supports an indirect, sympathetic effect of AVE 0118 similar to that of 4-AP, which is mediated, at least in part, by blocking neuronal KV 1.5 type potassium ion channels in the medio-adventitial layer of rat small mesenteric artery. © 2014 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    Tumor necrosis factor-alpha (TNF-α) is a pivotal mediator that triggers inflammatory process, oxidative stress, and multiple organ injury in sepsis. We investigated the effects of infliximab on survival, mesenteric artery blood flow (MBF), vascular reactivity, and oxidative and inflammatory injuries in cecal ligation and puncture (CLP)-induced sepsis. Wistar rats were divided into Sham, CLP, Sham+infliximab, and CLP+infliximab subgroups. Twenty-four hours before the operations, rats were injected intraperitoneally with infliximab (7 mg/kg) or vehicle (saline; 1 mL/kg). Twenty hours after the operations, MBF and phenylephrine responses of isolated aortic rings were measured. Tissue damages were examined biochemically and histopathologically. Furthermore, survival rates were monitored throughout 96 h. Infliximab improved survival, mesenteric perfusion, and aortic function after CLP. Increases of serum AST, ALT, LDH, BUN, Cr, and inflammatory cytokines (tumor necrosis factor-alpha, interleukin-1 beta, and interleukin-6) induced by CLP were blocked by infliximab. Infliximab prevented malondialdehyde elevations in septic liver, lung, spleen, and kidney tissues, as well as glutathione reductions in septic liver, spleen, and kidney tissues. Protective effects of infliximab on multiple organ damage were also observed histopathologically. Infliximab showed protective effects in sepsis due to its improvement effects on mesenteric perfusion, aortic function, and its anti-inflammatory and antioxidative effects.

    Pachydermodactyly (PDD) is a rare and benign form of digital soft tissues fibromatosis, which affects the skin of the fingers. The disorder is characterized by asymptomatic, symmetric, progressive soft tissue swelling of the proximal interphalangeal (PIP) joints of the fingers. The etiology of disease remains unknown. It is usually acquired, even though there are some publications that document family cases. It affects mainly adolescent men. We report two boys with the bilateral swelling of the of the PIP joints of the fingers and skin and subcutaneous tissue thickening. Based on clinical manifestations, radiological study and histopathological examination, pachydermodactyly was diagnosed. PDD is a rare and benign disorder, although it is important to consider other diseases, especially rheumatic conditions, in the differential diagnosis in order to avoid unnecessary additional tests and treatments.

    To compare the ancillary CT findings between superior mesenteric artery thromboembolism (SMAT) and superior mesenteric vein thrombosis (SMVT), and to determine the independent CT findings of life-threatening mesenteric occlusion. Our study was approved by the institution review board. We included 43 patients (21 SMAT and 22 SMVT between 1999 and 2008) of their median age of 60.0 years, and retrospectively analyzed their CT scans. Medical records were reviewed for demographics, management, surgical pathology diagnosis, and outcome. We compared CT findings between SMAT and SMVT groups. Multivariate analysis was conducted to determine the independent CT findings of life-threatening mesenteric occlusion. Of 43 patients, 24 had life-threatening mesenteric occlusion. Death related to mesenteric occlusion was 32.6%. A thick bowel wall (p < 0.001), mesenteric edema (p < 0.001), and ascites (p = 0.009) were more frequently associated with SMVT, whereas diminished bowel enhancement (p = 0.003) and paralytic ileus (p = 0.039) were more frequent in SMAT. Diminished bowel enhancement (OR = 20; p = 0.007) and paralytic ileus (OR = 16; p = 0.033) were independent findings suggesting life-threatening mesenteric occlusion. The ancillary CT findings occur with different frequencies in SMAT and SMVT. However, the independent findings indicating life-threatening mesenteric occlusion are diminished bowel wall enhancement and paralytic ileus.

    Background: Maintenance of mucosal healing is a primary goal when treating Crohn’s disease (CD). Endoscopy is the most precise method for the assessment of mucosal healing, but is considered overly invasive for patients with CD. In contrast, CT enterography (CTE) is less invasive, but little is known about the correlation between mucosal status and CTE parameters. Methods: We recruited CD patients who underwent CTE and double balloon endoscopy (DBE) on the same day at our hospital between 2012 and 2014. CTE parameters evaluated included bowel-wall thickening, mural hyperenhancement, mural stratification (target sign), submucosal fat deposition, mesenteric hypervascularity (comb sign), increased fat density, mesenteric fibrofatty proliferation, enlarged mesenteric lymph nodes, and stenosis/sacculation. Endoscopic findings were evaluated using the Simple Endoscopic Score for Crohn’s Disease (SES-CD). CTE parameters that were predictive of higher values in the SES-CD were extracted statistically. Results: Forty-one patients were recruited, from which 191 intestinal segments were evaluated. Spearman’s rank correlation coefficients showed that the majority of CTE values exhibited mild to moderate correlations with SES-CD values. Notably, multiple ordinal logistic regression analysis demonstrated that CTE findings obtained from the mesenteric area, such as mesenteric hypervascularity (comb sign) and enlarged mesenteric lymph nodes, were more critical predictors of endoscopic mucosal ulceration than those obtained from the bowel wall. Conclusions: This study was the first of its kind to assess correlations between CTE values and SES-CD values. Mesenteric findings of CTE, rather than mural findings, were highly correlated with the endoscopically evaluated severity of ulceration.

    To evaluate the feasibility and efficacy of urokinase infusion therapy via a transradial approach for transcatheter superior mesenteric artery (SMA) in patients with acute extensive portal and superior mesenteric venous thrombosis. During a period of 8 years, 47 patients with acute extensive thrombosis of portal vein (PV) and superior mesenteric veins (SMV) received urokinase infusion therapy by transcatheter selective SMA via radial artery. Their mean age was 44 ± 13 years (range: 19 - 65). Through radial sheath, a 5F catheter was placed into SMA and subsequently the infusion of urokinase was given for 5 - 11 days (mean: 7.1 ± 2.5). Adequate anticoagulation was initiated during treatment, throughout hospitalization and post-discharge. Follow-up contrast-enhanced computed tomography (CT) was performed in each patient every 3 days and before the removal of infusion catheter. Termination of urokinase infusion therapy was decided on the basis of clinical and radiographic findings. Technical success was achieved in all patients. Two patients had worsening abdominal pain, developed the signs of peritonitis at 24 hours after interventional treatment and underwent eventual laparotomy with the resection of necrotic bowel. Substantial clinical improvement was observed in 45 (95.7%) of them after the procedure. Minor complications at the radial puncture site were observed in 7 patients (14.9%) and infusion therapy continued. Follow-up CT scans at pre-discharge demonstrated a nearly complete disappearance of PV-SMV thrombosis in 29 patients (64.4%) and partial recanalization of PV-SMV thrombosis in 16 patients (35.6%). They were discharged at 9 - 20 days (mean: 12 ± 6) post-admission. The mean post-discharge duration of follow-up was 48 ± 20 months. Recurrent episodes of PV and SMV thrombosis were observed in 2 (4.4%) patients at 6 months and 5 years respectively post-discharge and they were treated successfully with urokinase infusion.

    The aims were to develop a method for real-time detection of histamine release and to test whether incubation with aldosterone induces histamine release from isolated, perfused mice mesenteric arteries. Fura-2-loaded HEK-293 cells transfected with the histamine H1 receptor was used as a sensitive biosensor assay for histamine release from isolated mouse mesenteric arteries. Activation of the H1 receptor by histamine was measured as an increased number of intracellular Ca 2+ transient peaks using fluorescence imaging. The developed biosensor was sensitive to histamine in physiological relevant concentrations and responded to substances released by the artery preparation. Aldosterone treatment of mesenteric arteries from wild-type mice for 50 min resulted in an increased number of intracellular Ca 2+ transient peaks in the biosensor cells, which was significantly inhibited by the histamine H1 blocker pyrilamine. Mesenteric arteries from mast cell-deficient SASH mice induced similar pyrilamine-sensitive Ca 2+ transient response in the biosensor cells. Mesenteric arteries from wild-type and SASH mice expressed histamine decarboxylase mRNA, indicating that mast cells are not the only source of histamine release. The developed biosensor assay can measure release of substances from vascular preparations. Histamine is released from the vessel preparation in response to aldosterone treatment independently of mast cells. The assay enables us to study a new signaling mechanism for vascular responses induced by aldosterone. © 2016 Scandinavian Physiological Society. Published by John Wiley & Sons Ltd.

    Full Text Available ABSTRACT INTRODUCTION: Some publications have demonstrated the presence of lung reperfusion injury in mesenteric ischemia and reperfusion (I/R, but under to diverse methods. Postconditioning has been recognized as effective in preventing reperfusion injury in various organs and tissues. However, its effectiveness has not been evaluated in the prevention of lung reperfusion injury after mesenteric ischemia and reperfusion. OBJECTIVE: To evaluate the presence of pulmonary reperfusion injury and the protective effect of ischemic postconditioning on lung parenchyma in rats submitted to mesenteric ischemia and reperfusion. METHODS: Thirty Wistar rats were distributed into three groups: group A (10 rats, which was held mesenteric ischemia (30 minutes and reperfusion (60 minutes; group B (10 rats, ischemia and reperfusion, interspersed by postconditioning with two alternating cycles of reperfusion and reocclusion, for two minutes each; and group C (10 rats, ischemia and reperfusion interleaved by postconditioning with four alternating cycles of reperfusion and reocclusion of 30 seconds each. Finally, it was resected the upper lung lobe for histological analysis. RESULTS: There were mild lung lesions (grade 1 in all samples. There was no statistical difference between groups 1 and 2 (P >0.05. CONCLUSION: The mesenteric ischemia and reperfusion in rats for thirty and sixty minutes, respectively, caused mild reperfusion injury in lung. Postconditioning was not able to minimize the remote reperfusion injury and there was no difference comparing two cycles of two minutes with four cycles of 30 seconds.

    The aim of this study is to analyze the chronological development of macroscopic, microscopic and magnetic resonance imaging (MRI) findings in a rat model of Superior Mesenteric Venous (SMV) ligation, and to evaluate the role of MRI in the diagnosis of mesenteric venous thrombosis. Thirty adult Sprague-Dawley rats were used and divided in two different groups that underwent a different surgical model and a different monitoring of ischemic damage. Group I underwent macroscopical and histological observation; Group II underwent 7T μMRI evaluation and histological analysis. The first alterations occurred 30 min after SMV ligation and progressively worsened until the eighth hour. The morphological and MRI findings showed the same course. This study provides a systematic evaluation of early anatomopathological and MRI findings following the SMV ligation. MRI allows to identify the early pathological findings of venous mesenteric ischemia and allows to correlate those to the histopathological features. Our data suggest a relevant role of MRI in the diagnostic management of mesenteric venous thrombosis, allowing to non-invasively identify and characterize the histopathologic findings. So, thanks to these skills, its future application in early diagnosis of human mesenteric venous ischemia is supposable. Copyright © 2013 Elsevier Inc. All rights reserved.

    PurposeTo assess the feasibility, effectiveness, and safety of catheter-directed thrombolysis and aspiration thrombectomy therapy by combined route of superior mesenteric vein and artery (SMV+SMA) for acute superior mesenteric venous thrombosis (ASMVT).MethodsThis retrospective study reviewed eight ASMVT patients with transcatheter direct thrombolysis and aspiration thrombectomy therapy via SMV and indirect thrombolysis via SMA during a period of 14 months. The demographics, etiology, risk factors, therapeutic effect, complications, mortality, and follow-up of the study population were assessed. Anatomic and imaging classification of location and extent of thrombus at diagnosis and degree of thrombus lysis were described.ResultsTechnical success was achieved with substantial improvement in symptoms and thrombus resolution after thrombolytic therapy in all patients. The local urokinase infusion by SMA and SMV was performed for 5–7 (6.13 ± 0.83) and 7–15 (12 ± 2.51) days. Anticoagulation was performed catheter-directed and then orally throughout hospitalization and after discharge. Four patients required delayed localized bowel resection after thrombolytic therapy with no death. Thrombolytic therapy was not interrupted despite minor bleeding at the puncture site in two patients and sepsis in another two postoperatively. Nearly complete removal of thrombus was demonstrated by contrast-enhanced CT scan and portography before discharge. Patients were discharged in 10–27 (19.25 ± 4.89) days after admission. No recurrence developed during the follow-up of 10–13 (12.13 ± 0.99) months.ConclusionsCatheter-directed thrombolytic and aspiration therapy via SMV+SMA is beneficial for ASMVT in avoiding patient death, efficient resolving thrombus, rapid improving symptoms, reversing extensive intestinal ischemia, averting bowel resection, or localizing infarcted bowel segment and preventing short bowel syndrome

Anticoagulation was performed catheter-directed and then orally throughout hospitalization and after discharge. Four patients required delayed localized bowel resection after thrombolytic therapy with no death. Thrombolytic therapy was not interrupted despite minor bleeding at the puncture site in two patients and sepsis in another two postoperatively. Nearly complete removal of thrombus was demonstrated by contrast-enhanced CT scan and portography before discharge. Patients were discharged in 10–27 (19.25 ± 4.89) days after admission. No recurrence developed during the follow-up of 10–13 (12.13 ± 0.99) months.ConclusionsCatheter-directed thrombolytic and aspiration therapy via SMV+SMA is beneficial for ASMVT in avoiding patient death, efficient resolving thrombus, rapid improving symptoms, reversing extensive intestinal ischemia, averting bowel resection, or localizing infarcted bowel segment and preventing short bowel syndrome.

    AIM: To investigate the role of second-look laparoscopy in patients with acute mesenteric ischemia (AMI). METHODS: Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room. RESULTS: The average time of admission to the hospital after the initiation of symptoms was 3 d (range, 5 h-9 d). In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% (n = 6). CONCLUSION: Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis.

    The protective effects of cannabidiol (CBD) have been widely shown in preclinical models and have translated into medicines for the treatment of multiple sclerosis and epilepsy. However, the direct vascular effects of CBD in humans are unknown. Using wire myography, the vascular effects of CBD were assessed in human mesenteric arteries, and the mechanisms of action probed pharmacologically. CBD-induced intracellular signalling was characterized using human aortic endothelial cells (HAECs). CBD caused acute, non-recoverable vasorelaxation of human mesenteric arteries with an Rmax of ∼ 40%. This was inhibited by cannabinoid receptor 1 (CB1) receptor antagonists, desensitization of transient receptor potential channels using capsaicin, removal of the endothelium, and inhibition of potassium efflux. There was no role for cannabinoid receptor-2 (CB2) receptor, peroxisome proliferator activated receptor (PPAR)γ, the novel endothelial cannabinoid receptor (CBe), or cyclooxygenase. CBD-induced vasorelaxation was blunted in males, and in patients with type 2 diabetes or hypercholesterolemia. In HAECs, CBD significantly reduced phosphorylated JNK, NFκB, p70s6 K and STAT5, and significantly increased phosphorylated CREB, ERK1/2, and Akt levels. CBD also increased phosphorylated eNOS (ser1177), which was correlated with increased levels of ERK1/2 and Akt levels. CB1 receptor antagonism prevented the increase in eNOS phosphorylation. This study shows, for the first time, that CBD causes vasorelaxation of human mesenteric arteries via activation of CB1 and TRP channels, and is endothelium- and nitric oxide-dependent. © The Author 2015.

    ACh-induced endothelium-dependent relaxation in rabbit small mesenteric arteries is resistant to N-nitro-L-arginine (L-NA) and indomethacin but sensitive to high K+, indicating the relaxations are mediated by endothelium-derived hyperpolarizing factors (EDHFs). The identity of the EDHFs in this vascular bed remains undefined. Small mesenteric arteries pretreated with L-NA and indomethacin were contracted with phenylephrine. ACh (10(-10) to 10(-6) M) caused concentration-dependent relaxations that were shifted to the right by lipoxygenase inhibition and the Ca(2+)-activated K+ channel inhibitors apamin (100 nM) or charybdotoxin (100 nM) and eliminated by the combination of apamin plus charybdotoxin. Relaxations to ACh were also blocked by a combination of barium (200 microM) and apamin but not barium plus charybdotoxin. Addition of K+ (10.9 mM final concentration) to the preconstricted arteries elicited small relaxations. K+ addition before ACh restored the charybdotoxin-sensitive component of relaxations to ACh. K+ (10.9 mM) also relaxed endothelium-denuded arteries, and the relaxations were inhibited by barium but not by charybdotoxin and apamin. With the use of whole cell patch-clamp analysis, ACh (10(-7) M) stimulated voltage-dependent outward K+ current from endothelial cells, which was inhibited by charybdotoxin, indicating K+ efflux. Arachidonic acid (10(-7) to 10(-4) M) induced concentration-related relaxations that were inhibited by apamin but not by charybdotoxin and barium. Addition of arachidonic acid after K+ (10.9 mM) resulted in more potent relaxations to arachidonic acid compared with control without K+ (5.9 mM). These findings suggest that, in rabbit mesenteric arteries, ACh-induced, L-NA- and indomethacin-resistant relaxation is mediated by endothelial cell K+ efflux and arachidonic acid metabolites, and a synergism exists between these two separate mechanisms.

    Acute superior mesenteric venous thrombosis (ASMVT) is an uncommon but catastrophic abdominal vascular emergency with high rate of intestinal failure and mortality. The retrospective pilot study was performed to assess the effect of a multidisciplinary stepwise management strategy on survival and mesenteric recanalization in an integrated intestinal stroke center (ISC). A modern management strategy performed by multidisciplinary specialists in ISC was evaluated among 43 ASMVT patients that were classified into central vs peripheral type, operative vs nonoperative, early vs late treated group from March 2009 to April 2013. Patients received specific medical therapy, endovascular treatment, damage-control surgery, selective second-look laparotomy, critical care management, and clinical nutrition support in a stepwise way. The demographics, etiology, imaging characteristics, treatment procedures, complications, clinical outcome, and 1-year follow-up data were analyzed and compared. Confounding factors of mortality were identified by univariate and ROC-curve analysis. A single-center experience of over 5years for this modern strategy was also reported. The protocol of multidisciplinary stepwise management strategy was followed in all ASMVT patients successfully. The 30-day mortality and recanalization rate were 11.63% and 90.70%. Initial damage-control surgery was carried out in 46.51% patients, with selective second-look laparotomy in 23.26% patients. Endovascular thrombolysis was performed in 83.72% patients initially or postoperatively. Bowel resection was necessary in 18 patients with the length of 100.00 (47.50, 222.50) cm. The incidence of short-bowel syndrome was 13.95%. The rate and length of bowel resection, short-bowel syndrome rate were significantly lower in nonoperative and early-treated groups (Pthrombosis.

    The prognosis of acute superior mesenteric venous thrombosis (SMVT) remains obscure. We aimed to investigate the treatment outcomes and possible risk factors for bowel infarction in these patients. We retrospectively included 66 patients with acute SMVT between January 2002 and June 2016. Each patient underwent contrast-enhanced computed tomography as part of the initial diagnosis. The standard protocol for management included a nonsurgical approach with early anticoagulation and selective exploration. For the analysis of the risk factors for bowel infarction, patients were divided into bowel resection (BR) and non-BR groups. Outcomes of interest were causes of SMVT, percentage of BR after nonsurgical treatment, and risk factors for BR. Of 66 patients, 15 (23%) underwent BR; of these, 9 underwent urgent BR because of peritoneal signs and definite findings of bowel infarction on computed tomography scan, 4 underwent BR after failed anticoagulation, and 2 underwent BR because of delayed stricture. Clinically, vomiting (P = .003), abdominal distention (P = .003), rebound tenderness (P = .005), and leukocytosis (P = .001) were associated with BR. On radiologic examination, bowel wall thickening (P thrombosis in addition to SMVT. All 15 BRs occurred in patients with combined PV thrombosis and SMVT (P thrombosis of the superior mesenteric vein and PV was also associated with BR (P = .028 for superior mesenteric vein; P = .025 for PV). BR was performed in 1 (4%) of 24 patients with transient risk factors compared with 14 (33%) of 42 patients without transient risk factors (P = .006). Three patients (4.5%) died in the hospital. In patients with acute SMVT, the extent of thrombus and etiology were associated with the severity of acute SMVT. Patients with transient risk factors and isolated SMVT tended to have a benign disease course. With early anticoagulation, acute SMVT does not seem to have the grave prognosis that is associated with arterial thrombosis

    Acrolein is generated endogenously during lipid peroxidation and inflammation and is an environmental pollutant. Protein adducts of acrolein are detected in atherosclerotic plaques and neurons of patients with Alzheimer's disease. To understand vascular effects of acrolein exposure, we studied acrolein vasoreactivity in perfused rodent mesenteric bed. Acrolein induced endothelium-dependent vasodilatation that was more robust and more sensitive than dilation induced by 4-hydroxy-trans-2-nonenal, trans-2-hexenal, or propionaldehyde. Acrolein-induced vasodilatation was mediated by K + -sensitive components, e.g., it was abolished in 0 [K + ] o buffer or in 3 mM tetrabutylammonium, inhibited 75% in 50 μM ouabain, and inhibited 64% in 20 mM K + buffer. Moreover, combined treatment with the Ca 2+ -activated K + channel inhibitors 1-[(2-chlorophenyl)diphenylmethyl]-1H-pyrazole (TRAM-34, 100 nM) and apamin (5 μM) significantly reduced vasodilatation without altering sensitivity to acrolein. However, acrolein-induced % dilation was unaffected by L-NAME or indomethacin pretreatment indicating mechanistic independence of NO and prostaglandins. Moreover, acrolein induced vasodilatation in cirazoline-precontracted mesenteric bed of eNOS-null mice confirming eNOS independence. Pretreatment with 6-(2-propargyloxyphenyl) hexanoic acid (PPOH 50 μM), an epoxygenase inhibitor, or the superoxide dismutase mimetic Tempol (100 μM) significantly attenuated acrolein-induced vasodilatation. Collectively, these data indicate that acrolein stimulates mesenteric bed vasodilatation due to endothelium-derived signal(s) that is K + -, ouabain-, PPOH-, and Tempol-sensitive, and thus, a likely endothelium-derived hyperpolarizing factor (EDHF). These data indicate that low level acrolein exposure associated with vascular oxidative stress or inflammation stimulates vasodilatation via EDHF release in medium-sized arteries - a novel function

    Internal herniation is a rare cause of intestinal obstruction, especially in the emergency department. We report a child with acute abdomen resulting from transmesenteric internal herniation of the small bowel. Radiographic findings revealed gaseous distension of the bowel loops in the upper abdominal area with a paucity of gas in the lower abdomen. Operative finding showed gangrenous small bowel due to mesenteric defect with an internal herniation. The gangrenous bowel was resected and the patient was discharged with an uneventful outcome. We emphasize that early recognition of internal herniation warrants further evaluation and appropriate management. Copyright © 2012. Published by Elsevier B.V.

    2012-02-01

    The effects of histamine and mechanisms of its action on the capsular smooth muscle cells of mesenteric lymph nodes were examined on isolated capsular strips under isometric conditions. Histamine (1×10(-8)-5×10(-7) M) decreased the tone of capsular smooth muscle cells and the frequency of phasic contractions. At high concentrations (more than 5×10(-6) M), histamine increased the amplitude and frequency of phasic contractions against the background of increased tonic stress. The effects of histamine were dose-dependent and were realized via direct stimulation of H(1)- and H(2)-receptors on the membrane of smooth muscle cells.

    We evaluated the usefulness of MRI and compared it with CT for diagnosis of mesenceric lymphoma in a dog. The results in the plain CT. dynamic CT and plain MR (TIWI and t2W1) images suggested that the mass was a large single nodular lesion with abundant blood perfusion. On enhanced MRI(T1WI) , the mass was depicted as a tumor with adhesion to the gut wall, Exploratory laparotomy confirmed the mass was consistent with the findings on enhanced MRI. We think that MRI might be a useful imaging tool for diagnosis of canine mesenteric lymphoma

    The authors report on a fatal mesenteric vein thrombosis following an uncomplicated percutaneous transhepatic portal vein catheterisation for the localisation of an insulinoma. Several hours after the procedure the patient developed an acute abdomen. An emergency laparotomy revealed a haemorrhagic infarct of the ileum. The resected specimen showed an acute phlebitis with fresh thrombus. The cause of the phlebothrombosis was thought to be intimal damage from high osmolar contrast medium. There was no evidence of damage due to the catheder, either on the phlebogram or pathologically. 1 fig.

    Acute superior mesenteric venous thrombosis (ASMVT) is an abdominal vascular condition. Early recanalization is essential to successful treatment. The aim of the study was to establish rabbit models of ASMVT and assess the time course of intestinal epithelial barrier disruption. After surgical exposure of superior mesenteric vein (Sham group), large-vessel (L-group) and small-vessel (S-group) models were established by endothelium damage, stenosis creation, and thrombin injection. At baseline, 6, 9, and 12 h, hemodynamic and serum parameters were tested. Serum from ASMVT patients diagnosed at 24, 36, 48, and 60 h from symptom onset was collected. Intestinal barrier disruption was assessed by tight junction (TJ) protein expression, morphology changes, and bacterial translocation. Mesenteric arteriospasm was measured by flow velocity and intestinal wet/dry weight ratio. The serum level of intestinal fatty acid-binding protein and endotoxin in patients was also measured as an indicator for intestinal barrier function. Severe acidosis and lacticemia were observed in both the groups. The L-group experienced greater hemodynamic alteration than the S-group. Intestinal barrier disruption was detected by significantly decreased TJ protein expression, histology and ultrastructure injury of TJ, increased permeability, and bacterial translocation, at 9 h in the S-group and 12 h in the L-group. Secondary mesenteric arteriospasm occurred at the same time of complete intestinal barrier disruption and could be a significant cause of bowel necrosis. Significant increased level of intestinal fatty acid-binding protein and endotoxin was found in patients at 48 h in the S-group type and 60 h in the L-group type. The ASMVT animal models of both the types were first established. The loss of intestinal barrier function occurred at 6 h in the S-group model and 9 h in the L-group model. For clinical patients, the time window extended to 36 h in the S-group type and 48 h in the L

    Full Text Available PRUPOSE: Bacterial translocation has been shown to occur in critically ill patients after extensive trauma, shock, sepsis, or thermal injury. The present study investigates mesenteric microcirculatory dysfunctions, the bacterial translocation phenomenon, and hemodynamic/metabolic disturbances in a rat model of intestinal obstruction and ischemia. METHODS: Anesthetized (pentobarbital 50 mg/kg, i.p. male Wistar rats (250-350 g were submitted to intestinal obstruction or laparotomy without intestinal obstruction (Sham and were evaluated 24 hours later. Bacterial translocation was assessed by bacterial culture of the mesenteric lymph nodes (MLN, liver, spleen, and blood. Leukocyte-endothelial interactions in the mesenteric microcirculation were assessed by intravital microscopy, and P-selectin and intercellular adhesion molecule (ICAM-1 expressions were quantified by immunohistochemistry. Hematocrit, blood gases, lactate, glucose, white blood cells, serum urea, creatinine, bilirubin, and hepatic enzymes were measured. RESULTS: About 86% of intestinal obstruction rats presented positive cultures for E. coli in samples of the mesenteric lymph nodes, liver, and spleen, and 57% had positive hemocultures. In comparison to the Sham rats, intestinal obstruction induced neutrophilia and increased the number of rolling (~2-fold, adherent (~5-fold, and migrated leukocytes (~11-fold; this increase was accompanied by an increased expression of P-selectin (~2-fold and intercellular adhesion molecule-1 (~2-fold in the mesenteric microcirculation. Intestinal obstruction rats exhibited decreased PaCO2, alkalosis, hyperlactatemia, and hyperglycemia, and increased blood potassium, hepatic enzyme activity, serum urea, creatinine, and bilirubin. A high mortality rate was observed after intestinal obstruction (83% at 72 h vs. 0% in Sham rats. CONCLUSION: Intestinal obstruction and ischemia in rats is a relevant model for the in vivo study of mesenteric microcirculatory

    Numerous cases of enamel renal syndrome have been previously reported. Various terms, such as enamel renal syndrome, amelogenesis imperfecta and gingival fibromatosis syndrome, and enamel-renal-gingival syndrome, have been used for patients presenting with the dental phenotype characteristic of this condition, nephrocalcinosis or nephrolithiasis, and gingival findings. This report describes a case of amelogenesis imperfecta of the enamel agenesis variety with nephrolithiasis in a 21-year-old male patient who complained of small teeth. The imaging modalities employed were conventional radiography, cone-beam computed tomography, and renal sonography. Such cases are first encountered by dentists, as other organ or metabolic diseases are generally hidden. Hence, cases of amelogenesis imperfecta should be subjected to advanced diagnostic modalities, incorporating both dental and medical criteria, in order to facilitate comprehensive long-term management.

    Numerous cases of enamel renal syndrome have been previously reported. Various terms, such as enamel renal syndrome, amelogenesis imperfecta and gingival fibromatosis syndrome, and enamel-renal-gingival syndrome, have been used for patients presenting with the dental phenotype characteristic of this condition, nephrocalcinosis or nephrolithiasis, and gingival findings.

    Full Text Available El quiste mesentérico es una enfermedad poco frecuente, cuya importancia ha sido menospreciada en demasiadas ocasiones en la literatura médica. La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento. Se realizó un estudio retrospectivo con revisión de los pacientes ingresados en el Servicio de Cirugía General y Digestiva del Hospital General de Castellón entre enero de 1990 y noviembre de 2005. Se diagnosticaron 4 quistes mesentéricos de los 34 355 ingresos en nuestro servicio. La mitad eran mujeres y la media de edad fue de 25 años. Tres casos presentaron síntomas y sólo uno fue un hallazgo casual. La manifestación clínica más frecuente fue el dolor abdominal leve y difuso. Uno de los pacientes se complicó con una perforación espontánea del quiste y peritonitis. El tratamiento fue la exéresis quirúrgica en todos los casos. Las vías de abordaje fueron: 3 laparotomías y 1 laparoscopia. Únicamente un caso requirió resección intestinal por déficit en la vascularización. No hubo ninguna recidiva tras la cirugía. A pesar de la baja frecuencia de esta enfermedad, su conocimiento es necesario ya que se pueden presentar síntomas cuando el quiste ha crecido, así como complicaciones graves (hemorragia, perforación, obstrucción intestinal, malignización, etc., que se pueden prevenir con la intervención quirúrgica, incluso en los casos asintomáticos
