Difficulty: HardCardiothoracic and Vascular Surgery

Post-operative complications following major cardiothoracic and vascular surgery require precise recognition and immediate intervention. Match each post-operative clinical scenario to the single most appropriate next step in patient management.

  • A 68-year-old male on postoperative day 3 following coronary artery bypass grafting develops abrupt hypotension, jugular venous distention, and electrical alternans on telemetry.Urgent transthoracic echocardiography and pericardiocentesis
  • A 71-year-old male on postoperative day 4 following open repair of an infrarenal abdominal aortic aneurysm complains of severe left lower quadrant abdominal pain and passes bloody stools.Flexible sigmoidoscopy to evaluate colonic mucosa
  • A 65-year-old female presents with sudden-onset bilateral lower extremity weakness, loss of pain sensation, and urinary retention 24 hours after an endovascular thoracic aortic aneurysm repair.Cerebrospinal fluid drainage and augmentation of mean arterial pressure
  • A 75-year-old male on postoperative day 1 after a right carotid endarterectomy exhibits a rapidly expanding, tense neck swelling accompanied by inspiratory stridor and hypoxia.Immediate bedside opening of the surgical incision and hematoma evacuation

Answer

Cardiac tamponade post-CABG is managed with echocardiography and pericardiocentesis. Ischemic colitis post-AAA repair requires flexible sigmoidoscopy. Spinal cord ischemia post-TEVAR requires CSF drainage and MAP augmentation. An expanding neck hematoma post-CEA requires immediate bedside wound opening.
Each post-operative scenario presents a classic, life-threatening complication unique to a specific cardiothoracic or vascular procedure. Matching the correct diagnostic or therapeutic next step requires integrating the surgical history with acute physiological changes (e.g., hemodynamic collapse, neurologic deficits, airway obstruction, or bowel ischemia).

Step-by-Step Solution

1
Analyze the post-CABG vignette
Identify Beck's triad and electrical alternans as definitive signs of cardiac tamponade.
To determine the need for urgent pericardial fluid evacuation and restore cardiac output.
2
Analyze the post-AAA vignette
Recognize bloody diarrhea and left lower quadrant pain as ischemic colitis.
The inferior mesenteric artery is routinely sacrificed during open AAA repair, leading to potential hindgut ischemia that requires visual assessment.
3
Analyze the post-TEVAR vignette
Identify anterior spinal cord syndrome characterized by motor loss and pain/temperature loss with preserved proprioception.
Spinal cord ischemia is a known, devastating complication of thoracic aortic interventions requiring immediate hemodynamic and CSF pressure adjustments.
4
Analyze the post-CEA vignette
Identify impending complete airway compromise from an expanding surgical site hematoma.
To recognize that delaying intervention for transport to the OR or for imaging is fatal; bedside decompression is the standard of care.
