“…The infarcted area usually appears as a patchy hypoechoic lesion on ultrasonography. [ 13 ] However, ultrasonography has a low sensitivity for acute splenic infarction. Abdominal CT performed with intravenous contrast remains the best method to confirm the diagnosis of splenic infarction, especially for patients in the hyperacute phase.…”

Rationale: Splenic infarction usually occurs in patients with underlying illnesses such as thromboembolic disorders and infiltrative hematologic diseases. Herein, we report a rare case of splenic infarction in a previously healthy boy diagnosed with infectious mononucleosis (IM). Splenic infarction is a rare complication of IM and its incidence is unknown. This case report summarizes the clinical characteristics, treatment options, and anticipated time for recovery from splenic infarction in IM. Patient concern: A16-year-old boy presented to our clinic with complaints of fever, sore throat, and general sweakness for 7 days. The patient was diagnosed with IM due to an Epstein–Barr virus infection. Two days later, the patient developed severe abdominal pain in the left upper quadrant and returned to our ER for further evaluation. Diagnosis: IM complicated with splenic infarction. Interventions: Contrast-enhanced CT confirmed the diagnosis of splenic infarction. This patient was admitted for supportive treatment and close medical monitoring. Surgical Outcomes: The patient recovered well with conservative treatment. Lessons: IM is most often seen in adolescents and young adults. Splenic infarction is a rare complication of IM, particularly in patients who do not usually have any underlying predisposing medical conditions. Contrast-enhanced CT is the imaging modality of choice in suspected cases. Early recognition and treatment of splenic infarction in patients with IM can help prevent potentially life-threatening events. Patients should be advised to avoid sports that may precipitate splenic rupture. However it is still unknown when it is safe for patients to resume sports. In our case, 6 weeks after the splenic infarction, the patient generally felt well with complete resolution of objective symptoms and splenomegaly, and resumed sports without experiencing any adverse events.

“…The measurement of spleen volume on imaging is often expressed by the splenic index, which is the longitudinal diameter Â the wide diameter Â the thick diameter. 33 The splenic longitudinal diameter usually determines the overall spleen size, however, this is not absolute, as the wide and thick diameters can also affect the spleen size. This may explain the erratic results of our study on the correlation between splenic length diameter and portal vein thrombosis.…”

“…Previous studies have shown a rebound of platelet count in proportion to the volume of the removed spleen, 30,32 thus broader splenic vein diameter often predicts a larger spleen volume increasing the risk of platelet aggregation to form blood clots. The measurement of spleen volume on imaging is often expressed by the splenic index, which is the longitudinal diameter × the wide diameter × the thick diameter 33 . The splenic longitudinal diameter usually determines the overall spleen size, however, this is not absolute, as the wide and thick diameters can also affect the spleen size.…”

BackgroundThe primary aim of the present study was to explore risk factors for portal vein system thrombosis following splenectomy.MethodsA systematic search of PubMed, Embase and Cochrane libraries was conducted to identify original studies that fulfilled the inclusion criteria. Raw data on potential risk factors for portal vein system thrombosis after splenectomy were extracted for meta‐analysis. Subsequently, a sensitivity analysis was conducted to verify the stability of the results.ResultsEighteen studies with 626 thrombosis events from 1807 splenectomy met the inclusion criteria. Larger spleen volume (SMD 0.44, P = 0.000), broader splenic vein diameter (WMD 2.30, P = 0.000), broader portal vein diameter (WMD 2.08, P = 0.000), a lower velocity of portal blood flow (WMD −0.91, P = 0.001), decreased platelet count (WMD −5.14, P = 0.007), decreased white blood cell (WMD −0.40, P = 0.027), decreased haemoglobin (WMD −9.14, P = 0.002), ascites (OR 1.81, P = 0.003) and bleeding history before surgery (OR 1.88, P = 0.002) were identified to be factors that exacerbated the risk of portal vein system thrombosis after splenectomy. Sex, age, preoperative prothrombin time, postoperative platelet count, postoperative D‐dimer, operation time and intraoperative blood loss, did not increase the risk of thrombosis.ConclusionLarger spleen volume, broader splenic vein diameter, broader portal vein diameter, a lower velocity of portal blood flow, ascites, bleeding history before surgery, decreased platelet count, white blood cell and haemoglobin may increase the risk of portal vein system thrombosis.

“…Various imaging modalities are employed for assessing splenic size, including ultrasound (US) [6][7][8][9][10][11], computed tomography (CT) [12][13][14][15][16][17][18][19], magnetic resonance imaging (MRI) [20,21], and nuclear scintigraphy [22][23][24], among which US and CT hold prominence [25,26]. US is often the first imaging method for evaluation of splenic size due to its widespread availability, cost effectiveness, and lack of ionizing radiation [2].…”

The accurate measurement of splenic size is essential for the diagnosis and management of various gastrointestinal and hematological conditions. While ultrasound (US) and computed tomography (CT) are widely used imaging modalities for assessing splenic size, discrepancies between their measurements have been observed in clinical practice. This study aimed to analyze the measurement differences between US and CT and identify factors influencing these differences. A retrospective analysis of 598 asymptomatic patients who underwent both abdominal US and CT was conducted. Measurements of splenic size obtained from US, axial CT, and coronal CT scans were compared, and various factors such as patient demographics, operator experience, and imaging parameters were evaluated to elucidate their impact on the measurement discrepancies. The results revealed that US consistently underestimated splenic size compared to CT. The magnitude of the discrepancy was influenced by factors such as patient age, body mass index (BMI), depth of the spleen from skin on US and that on CT, visibility of the splenic hilum on US, sonic window quality, and operator experience. This study underscores the importance of considering these factors when interpreting splenic measurements obtained from different imaging modalities in clinical practice.
