The presence of uncertain abdominal pain out of proportion to physical examination findings with the presence of risk factors is diagnostic of mesenteric ischemia.
Physical examination of patients with mesenteric ischemia can be normal in early stages or there may be mild abdominal distention in the absence of peritonitis which presents as rebound tenderness and guarding. As the ischemia progresses to involve all the layers of the intestine (transmural infarction), abdomen becomes distended, feculent ordor to the breath is present, peritoneal signs develop and bowel sounds become absent.

Overview

Physical examination of patients with mesenteric ischemia can be normal in early stages or there may be mild abdominal distention in the absence of peritonitis which presents as rebound tenderness and guarding. As the ischemia progresses to involve all the layers of the intestine (transmural infarction), abdomen becomes distended, feculent ordor to the breath is present, peritoneal signs develop and bowel sounds become absent. Signs of dehydration and shock may also appear if not treated in time.

Appearance of the Patient

  • Patients presenting with acute occlusive mesenteric ischemia are in acute distress while patients with chronic mesenteric ischemia may look malnourished due to sitophobia (fear of eating).

Vital Signs

  • Tachycardia with irregular pulse in case of atrial fibrillation
  • Tachypnea
  • Weak/bounding pulse

Skin

Neck

  • Jugular venous distension in case of congestive heart failure
  • Carotid bruits may be auscultated unilaterally/bilaterally using the bell/diaphragm of the otoscope in patients having atherosclerosis

Lungs

  • Asymmetric chest expansion / Decreased chest expansion
  • Lungs are hypo/hyperresonant
  • Fine/coarse crackles upon auscultation of the lung bases/apices unilaterally/bilaterally
  • Rhonchi
  • Vesicular breath sounds / Distant breath sounds
  • Expiratory/inspiratory wheezing with normal / delayed expiratory phase
  • Wheezing may be present
  • Egophony present/absent
  • Bronchophony present/absent
  • Normal/reduced tactile fremitus

Heart

  • Chest tenderness upon palpation
  • PMI within 2 cm of the sternum (PMI) / Displaced point of maximal impulse (PMI) suggestive of ____
  • Heave / thrill
  • Friction rub
  • S1
  • S2
  • S3
  • S4
  • Gallops
  • A high/low grade early/late systolic murmur / diastolic murmur best heard at the base/apex/(specific valve region) may be heard using the bell/diaphgram of the otoscope

Abdomen

Neuromuscular

  • Patient is usually oriented to persons, place, and time
  • Altered mental status
  • Glasgow coma scale is ___ / 15
  • Clonus may be present
  • Hyperreflexia / hyporeflexia / areflexia
  • Positive (abnormal) Babinski / plantar reflex unilaterally/bilaterally
  • Muscle rigidity
  • Proximal/distal muscle weakness unilaterally/bilaterally
  • ____ (finding) suggestive of cranial nerve ___ (roman numerical) deficit (e.g. Dilated pupils suggestive of CN III deficit)
  • Unilateral/bilateral upper/lower extremity weakness
  • Unilateral/bilateral sensory loss in the upper/lower extremity
  • Positive straight leg raise test
  • Abnormal gait (describe gait: e.g. ataxic (cerebellar) gait / steppage gait / waddling gait / choeiform gait / Parkinsonian gait / sensory gait)
  • Positive/negative Trendelenburg sign
  • Unilateral/bilateral tremor (describe tremor, e.g. at rest, pill-rolling)
  • Normal finger-to-nose test / Dysmetria
  • Absent/present dysdiadochokinesia (palm tapping test)

Extremities

  • Cyanosis
  • Pitting/non-pitting edema of the upper/lower extremities
