Q

Seatbelt

sign. What is it? Cause(s)

A

Bruising where a seatbelt was. Deceleration injury

29
Q

__________is the best initial test to evaluate free air under the diaphragm

A

Upright chest x-ray

Free air under the diaphragm indicates a perforation of the bowel.

30
Q

_______is the most appropriate next step in a patient suffering from acute mesenteric ischemia.

A

Angiography

31
Q

acute mesenteric ischemia. cx fx

A

complaints of abdominal pain 10/10 that is severe and out of proportion to physical findings. no guarding, soft abdomen, and no rebound tenderness.

32
Q

Ischemic Colitis pathop

A

lack of blood flow to the mesentery of the bowel. Ischemia of the bowel is most damaging to the mucosa.

33
Q

Ischemic Colitis cxfx

A

Abdominal pain that is described as cramping
Bloody diarrhea
+- fever

34
Q

Ischemic Colitis The best initial test

A

a CT scan of the abdomen.

35
Q

Ischemic Colitis most accurate test

A

angiography.

Colonoscopy with biopsy can also show ischemic mucosa, but it takes time for pathology to come back.

36
Q

Ischemic Colitis tx

A

IV normal saline and antibiotics if fever is present

37
Q

Acute mesenteric ischemia Patho

A

acute occlusion of mesenteric arteries, most commonly the superior mesenteric artery.

38
Q

The number one risk factor for Acute mesenteric ischemia is

A

atrial fibrillation, which can cause emboli to occlude the vessel.

39
Q

Acute mesenteric ischemia Cx Fx

A

excruciating pain that is out of proportion to the physical exam.

40
Q

Acute mesenteric ischemia labs

A

may show increased lactic acid and leukocytosis

41
Q

causes of abdominal pain that do not require surgery.

A

MI, GERD, lower lobe pneumonias, and acute porphyria

42
Q

Acute mesenteric ischemia best initial test is

A

abdominal x-ray showing air in the bowel wall.

43
Q

Acute mesenteric ischemia The most accurate test

A

angiography.

44
Q

Acute mesenteric ischemia most appropriate therapy.

A

Emergent laparotomy with resection of necrotic bowel

45
Q

Acute mesenteric ischemia . Endovascular therapy is indicated only if

A

there is a clear reason to avoid surgery.

46
Q

The most common locations for infarction are

A

watershed areas. Splenic flexure . rectosigmoid junction.

47
Q

Chronic mesenteric ischemia patho

A

results from atherosclerotic disease of 2 or more mesenteric vessels.

48
Q

In intestinal ischemia, _____is the equivalent of exertion in “chest pain with exertion.”

49
Q

Chronic mesenteric ischemia best diagnostic test is

A

angiography.. first to delineate the location of the lesions; then stenting or bypass reestablishes blood flow to allow surgical correction.

50
Q

Median Arcuate Ligament Syndrome (MALS) cxfx

A

severe postprandial abdominal pain, nausea, and weight loss.

51
Q

Median Arcuate Ligament Syndrome (MALS) patho

A

The condition is caused by external compression of the

celiac trunk by the median arcuate ligament.

52
Q

Median Arcuate Ligament Syndrome (MALS) dx

A

is a diagnosis of exclusion. Confirm with duplex ultrasonography to measure blood flow through the celiac artery.

53
Q

Median Arcuate Ligament Syndrome (MALS) tx

A

The general approach to treatment of MALS is surgical decompression of the celiac artery.

54
Q

A

Chollecystitis
Billiary colic

cream

A

“Brain freeze” secondary to rapid temperature change of the sinuses

61
Q

Q

Site of referred pain for Prostate

A

Tip of penis/perineum

65
Q

Site of referred pain for Appendix

A

Right lower abdominal quadrant
