Aortic Emergencies
Aortic dissection and aneurysm rupture are among the highest-acuity abdominal calls. RadCall covers Stanford and DeBakey classification, CTA protocol and findings, entry tear localization, and the distinction between type A and B management. AAA rupture signs and endoleak classification after EVAR are also included.
- Stanford classification — Type A vs Type B
- DeBakey classification — types I, II, III
- Intimal flap — true vs false lumen identification
- Entry tear — location, size, aortic involvement
- Malperfusion — visceral, renal, lower extremity
- AAA — diameter criteria, rupture signs
- Retroperitoneal hematoma — periaortic, psoas tracking
- Endoleak — Type I–V classification post-EVAR
Bowel Obstruction and Ischemia
Small and large bowel obstruction require urgent identification of closed-loop configuration, ischemia signs, and transition point. Mesenteric ischemia — arterial, venous, or non-occlusive — carries high mortality and requires pattern recognition on CT.
- Small bowel obstruction — simple vs closed-loop
- Closed-loop obstruction — C or U configuration, torsion
- Bowel ischemia — wall thickening, pneumatosis, portal gas
- Transition point — identification and cause
- Large bowel obstruction — colon cutoff, cecal diameter
- Mesenteric ischemia — SMA territory, CT angiography
- Mesenteric venous thrombosis — SMV, portal vein
- Volvulus — sigmoid vs gastric vs cecal
Solid Organ Trauma
AAST grading guides management decisions for splenic, hepatic, and renal injuries. RadCall covers each organ's grading scale, active extravasation identification, and embolization thresholds — the critical information needed when the trauma surgery team calls.
- Splenic laceration — AAST grade I–V
- Hepatic laceration — AAST grade, biloma risk
- Renal trauma — AAST grade, vascular pedicle
- Active extravasation — blush vs pseudoaneurysm
- Splenic embolization — criteria, proximal vs selective
- Pancreatic trauma — duct disruption, AAST grade
- Adrenal hematoma — trauma association
- Mesenteric injury — sentinel clot, bowel wall thickening
Acute Abdominal Conditions
- Appendicitis — CT and US criteria, Alvarado score
- Free air — pneumoperitoneum patterns and sensitivity
- Diverticulitis — Hinchey classification, complications
- Cholecystitis — acute vs gangrenous, Murphy sign CT
- Pancreatitis — Atlanta classification, CT severity index
- Ectopic pregnancy — US approach, beta-hCG correlation
- Ovarian torsion — US and CT findings, Doppler
- Ureteral stone — density, size, obstruction degree
