Causes angina or myocardial infarction
-Pain signal from Phrenic Nerve

20
Q

Myocardial Infarction

A

Sudden occlusion of a major coronary artery causing myocardium to undergo necrosis

  • Occurs mostly in the LAD (40-50%)
  • Second most in the Right Coronary Artery (30-40%)
  • Third most in the Circumflex Branch (15-20%)
21
Q

Cardiac Arrythmia

A

May occur if part of conducting system is damaged
-Asynchronous contraction of the heart ventricles

Can be corrected with an internal pacemaker

22
Q

Aortic Branch Variations

A

Normal branching (Left Subclavian, Left Common Carotid, and Brachiocephalic Trunk) is observed in only 65% of the population

23
Q

Aortic Coarctation

A

Stenosis of part of the Aorta

  • Can be preductal (infants) or postductal (adults)
  • Causes high pressure in the head and low pressure in the lower limbs

Leads to rib notching
-Rib gets worn down over time due to pulsating artery lying on top of bone

24
Q

DiGeorge Syndrome

A

Congenital immunodeficiency disorder caused by a deletion on Chromosome 22
-Most common cause of congenital thymic aplasia

Characterized by: (CATCH-22)

  • Cardiac Abnormalities
  • Abnormal Facies
  • Thymic Aplasia
  • Cleft Palate
  • Hypocalcemia
  • Deletion on Chromosome 22
25
Liposuction
Removal of Camper's Fascia using suction tube and high vacuum pressure Considered "botched" when too much is removed leading to an uneven structure of the skin
26
Patent Urachus
Urachus is an opening between bladder and umbilicus that should close at birth and become the Median Umbilical Ligament If left open, bladder infections can occur from opening Three types: - Urachal cyst - Urachal sinus - Urachal fistula
27
Prune Belly Syndrome
Associated with Patent Urachus Suspected if umbilical cord is enlarged with edema or slow to slough off Characterized by three main features: - Anterior abdominal wall muscles deficient or missing - Urinary tract abnormalities - Bilateral cryptorchidism (undescended testes) Believed to be caused by: - Urinary tract obstruction - Primary mesodermal development defect
28
Variocele
Blockage and engorgement of the Pampiniform Venous Plexus -Scrotum left feeling like a "Bag of worms" Occur more on the left side because of 90 degree angle from Left Renal Vein to Left Testicular Vein Can be caused by Nutcracker Syndrome or SMA syndrome
29
Direct Inguinal Hernia
Herniation passes MEDIAL to inferior epigastric vessels - Busts in to inguinal canal through side wall - Only passes through Superficial Inguinal Ring
30
Indirect Inguinal Hernia
Herniation passes LATERAL to inferior epigastric vessels - Passes through both Deep and Superficial Inguinal Rings - More than 2/3 of inguinal hernias
31
Duodenal Ulcers
- Ulceration of duodenal mucosa - Typically occurs along posterior aspect of the first part of the duodenum - Typically a result of Peptic Ulcer Disease, Chronic H. Pylori infection, smoking, NSAIDs - Gastroduodenal artery is most at risk for erosion
32
Portal Hypertension
Resistance to portal flow through the liver leading to regurgitation Due to: - Portal vein stenosis (pre-hepatic) - Cirrhosis (intrahepatic) - Right sided Heart failure (post-hepatic) Causes: - Encephalopathy - Ascites - Splenomegaly
33
Triangle of Calot
Anatomical landmark for locating the Cystic Artery Borders: - Superior: Inferior border of the Liver - Medial: Cystic Duct - Lateral: Common Hepatic Duct Contains: - Right Hepatic Artery - Cystic Artery - Lymphatics

35
Ligament of Treitz
Inferior extension from Diaphragm to Duodenum composed of skeletal and smooth muscle Landmark for surgical procedures -Duodenojejunal flexure Marks tie off point for removing bowel in an autopsy
36
SMA Syndrome
When the SMA compresses the Duodenum causing an obstruction in the GI tract -Can also compress the Left Renal Vein Can occur after significant weight loss, no extra fat to keep SMA extended Patient presents with: - Nausea - Vomiting - Early satiety
37
Appendicitis
Acute inflammation of the appendix Begins as vague periumbilical pain progresses to RLQ as inflammation spreads to the mesoappendix McBurney's Point - Imaginary line from umbilicus to ASIS to palpate appendix - If painful when palpating, indicative of appendicitis
38
Psoas Sign
Test for appendicitis -Extension of the right thigh to test for pain (stretching psoas muscle will irritate the mesoappendix eliciting a response)
39
Colon Cancer
Adenocarcinoma is most common malignancy of the GI tract Dietary factors: - Low fiber diet - High fat and carb intake Genetic factor: -APC Gene
40
Colostomy
Surgical procedure that fixes the colon to an opening on the skin - Done after intestinal surgery or resection - Waste passes through opening into collection system\
41
Diverticulosis
Mucosa pushes out between weakened muscle fibers in the sigmoid colon making pockets - Fecal matter impacts the pockets causing inflammation - Pockets can rupture leaving fecal matter in peritoneal cavity causing peritonitis or sepsis
42
Meralgia paresthetica
Painful neuropathy of the Lateral Femoral Cutaneous Nerve due to entrapment as it passes through the inguinal ligament Crossover to thigh is most common site of entrapment Occurs due to: - Pregnancy - Tight clothing - Obesity
43
Adrenal Insufficiency
Adrenal glands don't produce enough hormone Can lead to life threatening Adrenal Crisis (especially Tertiary) - Low blood pressure, glucose, sodium - High blood potassium Primary (Addison's Disease) -Adrenal glands are affected Secondary -Pituitary gland is affected Tertiary - Hypothalamus is affected - Can be caused by excessive Prednisone usage
44
Polycystic Kidney Disease
Multiple clusters of cysts on the kidneys Can cause kidney to swell: - Disrupts function - Chronic high blood pressure - Kidney infections - Renal failure
45
Kidney Stones
Form and become located in the Calices of the kidneys, ureters, or urinary bladder - If stone is sharp or larger than 3mm, it will distend the ureter and cause severe referred pain in the lumbar and inguinal regions - May lead to blood in the urine
46
Ureteric Jets
Visualization of normal efflux of urine from distal end of ureter into the bladder Used to assess obstructive uropathy
47
Incontinence
1 in 4 people over 65 have incontinence Stress Incontinence: - Increased abdominal pressure under stress - Weak pelvic floor muscles Urge Incontinence: -Involuntary contraction of bladder muscles Overflow Incontinence: -Blockage of the Urethra Neurogenic Incontinence: -Disturbed function of the nervous system
