Summary
Prophylactic splenic artery embolization using gelatin sponge may safely manage occult splenic hemorrhage after blunt trauma. This approach can minimize bleeding complications and reduce the need for further interventions.
Area of Science:
- Radiology
- Interventional Radiology
- Trauma Surgery
Background:
- Nonoperative management of traumatic splenic hemorrhage often involves embolization.
- Prophylactic embolization with absorbable gelatin sponge is considered when computed tomography angiography cannot exclude a splenic bleed.
Observation:
- This retrospective case series reviewed 4 patients with blunt abdominal trauma.
- Patients underwent prophylactic transarterial splenic artery embolization due to moderate splenic injury suggested by CT angiography, with no apparent hemorrhage on fluoroscopic angiography.
Findings:
- The study characterized demographic data and clinical outcomes of these patients.
- Periprocedural hemodynamic status, technical success, and postoperative complications were analyzed.
- Prophylactic embolization demonstrated potential safety and efficacy in managing occult splenic hemorrhage.
Implications:
- Prophylactic embolization with gelatin sponge may minimize bleeding complications in cases of occult splenic hemorrhage.
- This strategy has the potential to reduce the need for subsequent interventions in patients with blunt splenic trauma.

01:29Pulmonary Embolism I: Introduction
735
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

02:39lncRNA - Long Non-coding RNAs
10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

28.0K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
