The symptoms and signs of splenic rupture vary with the amount and speed of bleeding, the nature and extent of the rupture, and the presence or absence of combined or multiple injuries to other organs. In patients with only subperitoneal rupture or central rupture, the main manifestation is pain in the left upper abdomen, which may increase when breathing; at the same time, the spleen is mostly enlarged and has pressure pain, abdominal muscle tension is usually not obvious, there is no nausea or vomiting, and other manifestations of internal bleeding are not present. If incomplete rupture turns into complete rupture, acute symptoms will appear rapidly and the condition will deteriorate rapidly. Diagnostic laparotomy irrigation: Although it does not indicate the site of injury or the extent of injury, it is helpful in deciding the indications for dissection, with a diagnostic accuracy of more than 90%. Due to the widespread use of ultrasound and CT, the use of laparotomy seems to be limited. Radionuclide imaging: MRI is generally not used for the examination of emergency patients because of the long imaging time and the difficulty of access to MRI machines by certain resuscitation equipment, but it is a more effective examination method after stabilization or when the condition is complicated, especially when examining hemorrhage and hematoma. The various pathological changes after splenic trauma are reflected in MRI images basically the same as CT performance, while MRI can image in coronal and sagittal planes, which is more comprehensive than CT for showing overall changes and other organ injuries related to abdominal trauma. signal area, and at 3 to 14 days of bleeding, a white high-intensity signal is shown on T1-weighted images, and a high-intensity image is also shown on T2-weighted images. Selective abdominal arteriography: This is an invasive test with a high degree of specificity and accuracy, which allows both specific and definitive diagnosis and simultaneous super-selective splenic artery embolization therapy. Generally speaking, patients with splenic rupture can have the following 3 clinical processes: 1. early shock stage: it is a kind of reflex shock following abdominal trauma. 2.Middle insidious stage: The patient has recovered from early shock and the symptoms of internal bleeding are not yet obvious. The length of this period varies, from 3 to 4h for short cases, generally more than 10 hours to 3 to 5 days, and individual diseases such as subperitoneal bleeding or minor lacerations can also last up to 2 to 3 weeks before entering the obvious bleeding stage. During this period, the patient’s mild shock phenomenon has passed, and serious bleeding symptoms have not yet appeared, so the situation is mostly good; except for pain, pressure pain and muscle spasm in the left quarter rib area, there is only a vague local mass, the abdomen is slightly bulging, and radiating pain in the left shoulder is not common. However, if the diagnosis cannot be made in time, it is the main reason for the poor prognosis of most patients, so it is advisable to be cautious and not to be paralyzed or misunderstood because the history of trauma is not clear, the patient is still in good condition, there are no obvious symptoms of internal bleeding, and there is no typical Kehr’s sign or Ballance’s sign. 3.Late bleeding stage: At this stage, there is no doubt about the diagnosis, the bleeding symptoms and signs are very obvious, the patient’s condition has deteriorated, and the prognosis is more serious.
