Acute pulmonary embolism (PE) is the third most common cause of death in hospitalized patients. The development of sophisticated diagnostic and therapeutic modalities for PE, including endovascular therapy, affords a certain level of complexity to the treatment of patients with this important clinical entity. Furthermore, the lack of level I evidence for the safety and effectiveness of catheter directed therapy brings controversy to a promising treatment approach. In this review paper, we discuss the pathophysiology and clinical presentation of PE, review the medical and surgical treatment of the condition, and describe in detail the tools that are available for the endovascular therapy of PE, including mechanical thrombectomy, suction thrombectomy, and fibrinolytic therapy. We also review the literature available to date on these methods, and describe the function of the Pulmonary Embolism Response Team.
Spontaneous splenic rupture (SSR) is a rare but potentially life-threatening entity. It can be due to neoplastic, infectious, haematological, inflammatory and metabolic causes. An iatrogenic or an idiopathic aetiology should also be considered. Depending on the degree of splenic injury and the haemodynamic status of the patient, it can be managed conservatively. A 61-year-old man presented to the emergency department with an acute abdomen, hypovolaemic shock and clotting abnormalities. However, his focused assessment with sonography for trauma showed no evidence of an aortic aneurysm, rupture or dissection. Further investigation with a CT angiogram aorta confirmed a subcapsular splenic haematoma with free fluid in the pelvis and a mass in the superior pole of the spleen. He was diagnosed with an SSR. He was initially managed non-operatively. However, his repeat CT showed an enlarging haematoma and he underwent embolisation of his splenic artery. Ultrasound-guided core biopsy of his splenic mass confirmed the diagnosis of diffuse large B-cell lymphoma. This paper will discuss the clinical presentation, differential diagnosis and management of SSR. Furthermore, it provides an important clinical lesson to maintain a high index of clinical suspicion for splenic injury in patients presenting with left upper quadrant abdominal pain radiating to the shoulder. This case also reinforces the importance of close observation and monitoring of those individuals treated conservatively for signs of clinical deterioration.
A 68-year-old lady with end-stage chronic obstructive pulmonary disease presented with vomiting and abdominal pain. On examination her abdomen was grossly distended, diffusely tender and hyper-resonant. Imaging showed dilated loops of bowel and free air in the abdomen with no intestinal perforation. The free abdominal air had come down from the thorax by dissecting down around the oesophagus. A pneumomediastinum was present in her chest, secondary to her extensive emphysematous disease. She was treated conservatively and her pneumomediastinum resolved several weeks later, with subsequent resumption of intestinal motility and return to premorbid function. Surgical intervention would not have helped her condition.
Lobular capillary hemangioma (LCH) or pyogenic granuloma is a benign vascular tumor seen in children and adults, with a propensity to bleed profusely. Diagnosis can be made on the basis of sudden onset, rapid growth, history of trauma, and recurrent bleeding, though histopathological evidence is confirmatory. As these tumors do not usually regress spontaneously and have a high rate of recurrence, full-thickness surgical excision is a good option, especially in areas of low tension, such as the eyelids, as it offers satisfactory results with good aesthetic outcome and low chances of recurrence. Here, we report two cases of LCH over the upper eyelids, which were treated by full-thickness elliptical excision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
