Colonic Intramural Hematoma in a Cat: A Case Report.

ABSTRACT: Colonic intramural hematoma is a rare condition in humans and companion animals. Its clinical presentation in cats has not previously been reported. An 8-year-old male American shorthair cat presented with acute onset of constipation and anorexia for 3 days. Laboratory examination indicated mild elevation of alanine aminotransferase, globulin, and total protein levels. Complete blood count was normal. Radiographs revealed a soft tissue opacity mass located caudodorsally to the urinary bladder, causing narrowing of the descending colonic lumen. Sonography showed a heteroechogenic intraluminal mass containing liquefied content between the submucosal and muscular layers of the descending colon. On computed tomographic images, the mass contained two different attenuated contents with an interface. Colonoscopy was then performed for intestinal biopsy, and the contents observed in the intraluminal mass were drained via surgical evacuation and considered as blood clots. Supportive medical treatment, including antibiotics and fecal softener, was administered, and the clinical signs resolved uneventfully. Mild chronic proctitis without apparent malignancy was confirmed histopathologically, and no recurrence was observed after more than 14 months, and thus a colonic intramural hematoma was presumptively diagnosed. The information provided by multimodal imaging of the mass was essential for the diagnosis and determination of the treatment in this case.

Gastric intramural hematoma subsequent to thoracic aortic dissection: Case report and literature review.

Project description:IntroductionIntramural hematomas of the gastrointestinal tract are uncommom, usually located in the esophagus or duodenum, with idiophatic or secondary causes. We present a very rare case of gastric intramural hematoma caused by an unpublished etiology, with literature review.Case presentationAn elderly woman suffered acute thoracic aorta dissection followed by gastric intramural hematoma, diagnosed through endoscopy and computed tomography angiography. The treatment included endovascular aortic repair and conservative management.DiscussionThe postulated mechanism for the bleeding in gastric intramural hematoma is shredding of terminal arteries at the point of penetration into the muscular layer with subsequent dissection of the muscularis propria from the submucosa. The most frequently cited risk factor is hemorrhagic diathesis/anticoagulant use and the main etiologies are trauma and post-interventional endoscopy. In the diagnosis work-up, computed tomography is the method of choice, usually associated with endoscopy. There is no standard of care for such rare condition. Thus, treatment may be cause-dependent, ranging from conservative to minimally invasive and/or surgery.ConclusionsGastric intramural hematoma is a rare disorder with many causes and we described a new etiology for it. The computed tomography is the diagnostic modality of choice, with the aid of other examinations. The treatment comprises conservative measures, minimally invasive approach or most commonly surgery.

Iatrogenic Acute Ascending Aortic Dissection with Intramural Hematoma during Coronary Artery Stenting: A Case Report.

Project description:BackgroundIatrogenic acute ascending aortic dissection during percutaneous coronary intervention (PCI) is an exceptionally rare and life-threatening sequel that requires early and accurate diagnosis along with rapid management. No guidelines have yet been established to direct decisions on the different treatment options that can be employed in the setting of acute aortic dissections caused by PCI. However, similar cases have been treated either by intracoronary stenting and conservative management as in localized aortocoronary dissections or by surgical intervention in cases of extensive aortic dissections.Case summaryHereby, we present a rare case of a female patient who developed "full-blown" acute ascending aortic dissection (Stanford type A-DeBakey type II dissection) with intramural hematoma during an elective percutaneous transluminal coronary angioplasty (PTCA) of the right coronary artery (RCA) and left circumflex artery (LCA). Accordingly, emergent surgical repair of the dissected aorta was performed including grafting of supracoronary ascending aortic tube, along with coronary artery bypass graft placement and septal myomectomy for severely hypertrophied cardiac septum. The patient recovered successfully without any documented postoperative complications.ConclusionIt is pivotal to avoid aggressive use of instrumentation during PTCA in order to prevent the potential development of catheter-induced aortic dissection.

Post myocardial infarction left ventricular intramural dissecting hematoma: a case report describing a very rare complication.

Project description:BackgroundDissecting intramural hematoma is a rare complication of acute myocardial infarction (AMI) and has been associated with increased mortality. There has been paucity of literature to establish protocols and guidelines for management in such cases.Case presentationWe hereby report the case of a 45-year-old male patient with left ventricular intramural dissecting hematoma (LV-IDH) who presented with chest pain and breathlessness and diagnosed as non-ST-elevation myocardial infarction (NSTEMI). Transthoracic echocardiography (TTE) was performed showing LV-IDH, confirmed with cardiac magnetic resonant imaging (cMRI). Selective coronary arteriography (CAG) was performed showing significant obstructive coronary artery disease (CAD). Further management with conservative approach involved discussion with patient, cardiothoracic surgeon and cardiology team including heart failure specialist and interventional cardiology.ConclusionsThis case describes a rare complication of AMI and also focuses on utility of TTE and cMRI in the diagnosis of this rare complication. Both diagnosis and management are challenging and have to be individualized in similar cases. Multidisciplinary care coordination is important in management of patients with this diagnosis.

Conservative treatment of a left atrial intramural hematoma after left atrial thrombus resection and concomitant mitral valve replacement--case report.

Project description:Left atrial intramural hematoma is a seldom cause of left atrial mass. It has been described to occur spontaneously, after interventional procedures, after blunt chest trauma, or after aortocoronary bypass surgery. We present a case of mitral valve replacement together with the removal of a large intraatrial space-occupying lesion. Intraoperative transesophageal echocardiography confirmed a successful resection of this mass. Surprisingly, upon admission to ICU, transesophageal and transthoracic echocardiography revealed a recurrence of an intramural lesion, closest matching a hematoma, which was confirmed by contrast-enhanced computed tomography. Surgical intervention was thoroughly discussed but a conservative management was favoured. 3 months after surgery, a reassessed transthoracic echocardiography and computed tomography demonstrated an almost complete resolution of the pre-existing hematoma.

Nontraumatic bilateral subdural hematoma: Case report.

Project description:A subdural hematoma (SDH) is a type of bleeding in which a collection of blood gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. Although most cases reported of subdural hematoma are due to traumatic brain injury, to the best of our knowledge this is a rare case of nontraumatic subdural hematoma. A 31 year-old-Male presented to the emergency department with a severe headache for 3 weeks, with the presence of oculomotor disorders. There is no history of major trauma, minor trauma or fights. Also, no history of hypertension, or Haematological diseases. Magnetic resonance imaging (MRI) showed bilateral subdural hematoma. The right-sided hematoma was treated conservatively and the Left-sided was treated by surgery. Follow-up for three months revealed no recurrence. Nontraumatic subdural hematoma is one of the challenging cases that neurosurgeons face. We presented a patient with idiopathic spontaneous subdural hematoma. Computed tomography (CT) is the first step for diagnosis and Magnetic resonance imaging (MRI) is considered an excellent imaging investigation to evaluate such patients. Symptomatic subdural hematomas require an emergent treatment by identifying and controlling sites of bleeding conservatively or by surgery. Subdural hematoma with no history of trauma should be treated emergently and evaluated strictly. Follow-up is essential in patients with neural symptoms. Massive symptomatic subdural hematoma (SDH) should be treated with surgery to control the bleeding.

Spontaneous retroperitoneal hematoma: a case report.

Project description:BackgroundSpontaneous retroperitoneal hematoma is defined as bleeding in the retroperitoneal space without any triggers such as trauma, invasive procedures, and abdominal aortic aneurysm.Case presentationA 48-year-old Japanese man who experienced sudden abdominal pain, severe hypotension, and decreased hemoglobin was diagnosed with spontaneous retroperitoneal hematoma. Contrast-enhanced computed tomography revealed massive left retroperitoneal hematoma; however, neither extravasation nor causative aneurysm was noted. Through conservative management with close monitoring, he was treated and discharged on the tenth hospital day without any morbidity.ConclusionsSpontaneous retroperitoneal hematoma treatment comprises conservative management, transcatheter arterial embolization, and surgical intervention. The mortality rate of spontaneous retroperitoneal hematoma is so high that the optimal treatment timing needs to be carefully judged on the basis of detailed evaluation, and management algorithm with clear criteria.

Aortic luminal thrombus and intramural hematoma after cardiopulmonary resuscitation.

Project description:We describe the case of a patient with an intramural hematoma and floating thrombus after cardiopulmonary resuscitation. The 92-year old man had a cardiac arrest due to ventricular fibrillation and witnesses immediately initiated manual cardiopulmonary resuscitation. Transesophageal echocardiography was performed immediately on hospital admission because the patient was in cardiogenic shock. In addition to an akinetic anterior wall, examination of the descending thoracic aorta demonstrated an intramural hematoma and a floating intra-aortic thrombus at a distance of 40cm from the dental arch. There was no aortic dissection. The thrombus was attributed to aortic compression during cardiopulmonary resuscitation. Although the aortic thrombus and intramural hematoma were not associated with any complications in this patient, insertion of an intra-aortic balloon may have led to aortic rupture or embolic events. Transesophageal echocardiography should be performed, when available, prior to insertion of an intra-aortic balloon for counterpulsation in patients who have undergone cardiopulmonary resuscitation.

Facial hematoma of endodontic origin: A case report.

Project description:Endodontic treatment is a common procedure in dentistry that consists of elimination of organic tissues, infected debris, and pathogenic bacteria from the canal system by means of mechanical instrumentation associated with abundant disinfecting agents (Haapasalo et al., 2005) [1]. Despite progress with its implementation, dentists may at any time be faced with complications during or after a root canal procedure. While some of these problems can be anticipated, many can never really be predicted. A complication such as a hematoma that is usually seen as a complication of trauma or oral surgery, is rarely seen after a simple endodontic treatment. It put the dentist in a confused and uncomfortable situation. Dentists should be aware of the possible occurrence of this incident and should know what can cause it and how to manage it. We report the case of a 63-year-old patient, referred by her general dentist to our center for the sudden onset of a facial hematoma after endodontic treatment.
