WINNING THE BATTLE BUT LOSING THE WAR A Brief Case Presentation Michael Caselnova, M.D.
GOALS • Case presentation • Brief review of diagnoses encountered • Lessons learned • Recommendations to improve care
The Case • Day 0 • 67 y/o WM presented to another facility with: • Abdominal pain • Hypotension • Diaphoretic • “pale”
ADDITIONAL FINDINGS • CT abdomen showed: • 7 cm AAA with large retroperitoneal hematoma • PMH significant for coronary stent
The Problem? • NO Cardiothoracic surgeon available at the outlying facility • Decision made to transfer pt by air to our facility • Transfused during transport • Met by CT surgeon and anesthesiology on helipad and taken directly to OR
FINDINGS ON ARRIVAL • SBP in 60-80 range • Cyanosis of abdomen and legs • No peripheral pulses • As he was being placed on table: • pH 6.8 • SBP unobtainable
Procedure • “EMERGENCY LIFE SAVING REPAIR OF ABDOMINAL AORTIC ANEURYSM” • 18 mm straight dacron tube graft
Findings at time of surgery • Large retroperitoneal hematoma, R>L • Compression of vena cava • Free intra abdominal blood • Coagulopathy • Hypothermia 33.8 degrees • ? Hepatic tumor on palpation • TEE showed good LV function • BP 120/70 post op
Received • 15 units PRBC • 10 units FFP • 20 units cryoprecipitate • Platelets • TPN post op
POD 1 Small mucoid bloody stools x 7 • POD 2 2 more bloody stools and abd pain • GI consult • CT read as 3.5-4 cm exophytic liver mass • Alk phos normal • Bili normal • AST 165
Preliminary Dx • Ischemic colitis from profound hypotension • Needs CT w contrast but Azotemic • AFP requested (later came back normal)
POD 4 • Neurology consult for weakness and numbness of lower extremities • Initial impression: • Either direct compression of lumbar plexus by retroperitoneal hematoma or • Cord ischemia due to hypotension • Prognosis good for recovery of function
POD 5 • Colonoscopy: ischemic colitis in section of rectum and sigmoid and descending colon • No areas of circumferential ischemic colitis • No areas that looked like they wouldn’t heal • Rec: FEED
POD 9 • Fever to 102.6 • Pulmonary consult • Atelectasis on CXR • WBC on POD 8 was 19.5 • Had been started on Moxi and Vanc • Blood Cult growing GNR • Moxi stopped and pip/tazo added
POD 12 • BC growing Pseudomonas and Klebsiella pneumoniae • Urine C&S 2 GNR • Few candida from central line • ID consult- candida felt likely colonization BUT concern for graft so fluconazole rec for 2-4 wks • One culture pos for staph epi sens to all • Vanco stopped
POD 18 • Discharged to ECF in outlying city • Fluconazole for 30 days po • Pip/tazo for one more week • BATTLE WON! • BUT…..
POD 37 • Brought to ER with fever, nausea, vomiting abd pain • No dysuria • Few days of diarrhea but no hematochezia • CT: air and fluid in aortic lumen, surrounding the graft, and anterior to aorta at level of prox graft anastomosis consistent w infection/abscess formation • Abnormal area of low attenuation in liver- possible infarct/infection/can’t exclude mass
Transfer to our facility • CT surgeon accepted pt- felt the air and fluid were expected findings post op • Hospitalist Consult requested • Afebrile on arrival • Pt was on oral cipro and augmentin • WBC 11K, Hgb 12.2, plt 127K, alb 1.9, alk phos 409, CXR w hazy opacity R either atelectasis or infiltrate, but improved from previous
Cultured again • Pip/tazo and vanco • C dif neg • Gram pos cocci in 1of 2 BC from referring facility • RUQ tenderness • NO mention of hepatic mass in the DC summary
RUQ sono-thickened GB wall and sludge • Amylase and lipase normal • Gen Surg consult • HIDA neg for acute cholecystitis and EF was 42%; decreased uptake R side of liver
POD 44 • Renal function worsening BUN 49, Cr 2.9 • Plt 76K, WBC 15.8, INR 2.87 • Nephrology Consult-? Vanco, ? ATN, ? obstruction • Renal sono normal • Start CRRT dialysis • CT directed liver Bx done POD 41-results pending
POD 45 • ID consult- ? Sepsis • Vanco continued but imipenem added • Transaminases increasing, ? Hepatorenal syndrome • Heme/onc consult for liver mass (path still pending) • Can’t treat malignancy due to overall condition
POD 46 • CTA chest/abd/pelvis • Increasing R pleural effusion • Increasing ascites • Perigraft fluid w air, ? Infectious process • Decision made w family to change status to DNR
POD 47 • Pt expired • Final Dx on liver Bx was primary malignant liver neoplasm-report signed on POD 54 • LOST THE WAR
Abdominal Aortic Aneurysm • Diameter > 3.0 cm at level of renal arteries • Risk factors include age1,2, smoking3, male sex4, HTN5, family Hx1, atherosclerosis • Most are asymptomatic until rupture, but if symptoms are present (abd or back pain or tenderness on palpation) the risk for rupture is higher • Ruptured AAA typically presents with abd or back pain, hypotension, pulsatile abd mass
AAA • Overall survival rate for ruptured AAA is 25%; 50% survive to reach hospital but 50% reaching hospital don’t survive6 • If BP is stable, the aneurysm rupture is temporarily contained
ISCHEMIC COLITIS • Caused by reduction in intestinal blood flow, by occlusion, vasospasm, or hypoperfusion of mesenteric vessels • More common in elderly • Majority develop non-gangrenous ischemia and resolve w/o sequelae, but can develop stricture7 • 15% develop gangrene7 • Splenic flexure and rectosigmoid junction most vulnerable sites • Occurs in 1-7% of aortoiliac surgery8,9
ISCHEMIC COLITIS • Findings include: • Abdominal pain and tenderness which is usually mild • Rectal bleeding or bloody diarrhea within 24 hrs of onset of pain • May develop ileus or proceed to severe gangrene with shock
ISCHEMIC COLITISDX • CLINICAL SETTING • PHYSICAL EXAM • RADIOLOGIC • ENDOSCOPIC • NO SPECIFIC LAB FINDINGS • PLAIN FILMS USUALLY NON SPECIFIC • MRI/MRA NOT USEFUL • CT W CONTRAST OFTEN NONSPECIFIC • COLONOSCOPY WITHOUT PREP, MINIMAL AIR INSUFFLATION
ISCHEMIC COLITIS TX • In absence of perforation or gangrene • Supportive care, bowel rest, IVF to maintain perfusion • Empiric broad spectrum Abx • NGT if ileus present • ? TPN
ISCHEMIC COLITISTX • Surgical intervention if clinical worsening • Surgical intervention for colonic infarction • Generally surgery performed without prep
PRIMARY HEPATOCELLULAR CARCINOMA • Usually develops in setting of chronic liver Disease • Often untreatable at time of Dx • Usually asymptomatic until late in course • Fever may develop with central tumor necrosis • Lab findings usually nonspecific • AFP not elevated in all cases- 40% are normal12 • Extrahepatic spread in 10-20% at time of Dx10, 11
Primary hepatocellular carcinoma • Most common metastase are to lung, intraabdominal lymph nodes, bone, adrenal gland
PRIMARY HEPATOCELLULAR CARCINOMA DX • Usually have underlying liver disease • Rising alpha fetoprotein (but not all tumors secrete AFP) • CT or MRI- dominant solid nodule, hypervascular, venous invasion with elevated AFP • Percutaneous Bx
AAA POST OP • Hematoma present in all patients-usually resolves in 7-65 days in 82% of patients • Perigraft fluid resolves over 3 mos • Perigraft gas usually resolves in one week
LESSONS LEARNED • INCLUDE IN DISCHARGE SUMMARY ANYTHING SIGNIFICANT WHICH NEEDS FOLLOW UP-SUBSEQUENT PROVIDERS WILL BE RELYING ON IT • REVIEW OTHER MEDICAL RECORDS WHEN RE ADMITTING PATIENT- PRIOR H&P, CONSULTS, RADIOLOGY, ETC
LESSONS LEARNED • TRY TO GET CONSULTING HOSPITALIST TO DO DISCHARGE SUMMARY AND DEATH CERTIFICATE • JUST KIDDING!
