 Medical Report: allergies: ganciclovir / acyclovir attending: chief complaint: the patient was admitted on for a liver transplant. major surgical or invasive procedure: liver transplant history of present illness: mr. is a 53m w/ hx hep c cirrhosis and hcc. he presented for a liver transplant. he has not had any fevers, and chills. no diarrhea, nausea or vomiting. no urinary symptoms. no cough. no shortness of breath. he has night sweats at baseline but this has not increased and has actually improved. he ate at 1830. past medical history: hcv, hcc, htn, osteoporosis psh: lap ccy, cervical laminectomy with fusion, tib/fib fx s/p fixation with steel rod. social history: former smoker who has quit in . he smoked 2 packs per day for 40 years. he denies any alcohol or drug use. family history: unremarkable physical exam: vs: t 97.4 hr 91 bp 135/73 rr 20 o2sat 98% ra nad, aaox3, he is w/o asterixis. heent: nc/at,and anicteric. neck is supple w/o lymphadenopathy. cv: regular rate and rhythm pulm: cta b/l abd:soft/nontender/distended/+bs. no splenomegaly. there is no guarding or rebound tenderness. ext: no peripheral edema pertinent results: 05:05am blood wbc-8.5 rbc-2.86* hgb-8.9* hct-26.2* mcv-92 mch-31.0 mchc-33.8 rdw-15.9* plt ct-164 05:05am blood plt ct-164 05:05am blood pt-11.9 ptt-20.3* inr(pt)-1.0 04:45am blood fibrino-251 05:05am blood glucose-76 urean-29* creat-1.0 na-140 k-4.6 cl-103 hco3-31 angap-11 05:05am blood alt-941* ast-108* alkphos-83 totbili-0.7 04:45am blood lipase-19 05:05am blood albumin-3.3* calcium-8.6 phos-3.8 mg-2.4 05:05am blood fk506-7.2 01:34pm ascites totbili-1.4 duplex dop abd/pel limited 2:33 pm duplex dop abd/pel limited reason: flow/ fluid collection. s/p liver tx medical condition: 53 year old man with liver transplant reason for this examination: flow/fluid collcetion .indication: 53-year-old man with liver transplant today, evaluate for fluid collection and flow in vessels. findings: the liver shows no focal abnormalities. there is a tiny trace of fluid in morison's pouch but no other fluid collections are identified. there is no biliary dilatation seen. doppler examination: hepatopetal flow is identified in the main portal vein, the right portal vein, and the left portal vein. velocity of flow within the main portal vein is 52 cm/sec. appropriate flow is identified in the hepatic veins. arterial waveforms in the main hepatic artery, right hepatic artery, and left hepatic artery are appropriate with good upstrokes. flow is identified within the ivc; however, this vessel is not well imaged on this exam. impression: tiny trace of fluid in morison's pouch. appropriate flow is identified in all of the hepatic vessels. duplex dopp abd/pel 11:58 am liver or gallbladder us (singl; duplex dopp abd/pel reason: need to look at arterial and venous flow of transplanted liv medical condition: 53 year old man s/p liver transplant reason for this examination: need to look at arterial and venous flow of transplanted liver. look for any fluid collections indication: 53-year-old man status post liver transplant. -scale and doppler ultrasound of the liver: comparison was made with the prior ultrasound dated . again note is made of a small amount of fluid in pouch, as seen on the prior study. otherwise, the appearance of the liver is unchanged on -scale images. hepatopetal flow is identified in the main and right and left portal veins. the velocity of flow within the main portal vein is 56 cm/sec. hepatic veins are patent with appropriate waveforms. main and right and left hepatic arteries show appropriate arterial waveform with good stroke as noted previously. the proximal right hepatic artery is visualized with normal waveforrms, but peripherally assessment is somewhat limited. impression: small free fluid in morison's pouch as noted previously. patent vessels with appropriate waveforms as described above. note that distal right hepatic artery is not fully visualized on this study--correlate clinically with lab values, and followup if indicated. ct abd w&w/o c 1:33 pm ct abd w&w/o c reason: cta of the liver. smaller cuts around the liver to evaluate field of view: 39 medical condition: 53 year old man s/p liver transplant. reason for this examination: cta of the liver. smaller cuts around the liver to evaluate hepatic artery. need to evaluation for hematoma and bleeding. only need iv contrast contraindications for iv contrast: none. ct liver (multiphase) indication: status post liver transplant. technique: non-contrast, arterial phase and portal venous phase ct liver performed. findings: the portal vein is patent. the donor hepatic artery has been surgically anastomosed to the recipient replaced hepatic artery which arises from the patient's celiac artery. the left and right hepatic arteries and the proper hepatic artery are patent. there is mild dilatation of the donor hepatic artery at the anastamosis. there is a focal wedge- shaped area of patchy hypoattenuation on portal venous and arterial phase in segment vii of the liver possibly representing a focal area of contusion related to recent surgery. there is some periportal edema in segment ii and also in segment ivb. remainder of the liver enhancement is normal on arterial and portal venous phases. the hepatic veins are patent. the spleen is enlarged measuring 14.6 cm in diameter. the pancreas, kidneys, and adrenal glands are normal. there is a small amount of intraperitoneal air. there is perihepatic fluid and some hematoma, consistent with recent surgery. there is mild right basilar collapse consolidation and a small right pleural effusion. impression: 1. patent hepatic vasculature. 2. right basal collapse/consolidation. brief hospital course: the patient was admitted on for a liver transplant. on admission, he was made npo, and pre-op blood work, ekg and cxr were obtained. the patient tolerated the procedure well and was admitted to the icu intubated following surgery for close monitoring. on sedation was weaned, the patient was extubated. ultrasound showed: hepatopetal flow is identified in the main portal vein, the right portal vein, and the left portal vein. velocity of flow within the main portal vein is 52 cm/sec. appropriate flow is identified in the hepatic veins. arterial waveforms in the main hepatic artery, right hepatic artery, and left hepatic artery are appropriate with good upstrokes. flow is identified within the ivc; however, this vessel is not well imaged on this exam. on the patient was transferred to 10 for continued monitoring. he was encouraged to ambulate, started on a regular diet and his fluids were stopped. - the patient's home medications were started and his foley catheter was removed. the patient continued to do well, a ct abdomen was performed on showing patent hepatic vasculature. he is to be discharged home on . medications on admission: : actigall 300 mg q.i.d., diovan 160 mg daily, omeprazole 20 mg daily, calcium with vitamin d twice a day, multi-vit, b complex vitamin, boniva 3 grams every 3 months, started on an antihistimine for itching. discharge medications: 1. furosemide 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 2. fluconazole 200 mg tablet sig: two (2) tablet po q24h (every 24 hours). disp:*60 tablet(s)* refills:*2* 3. valganciclovir 450 mg tablet sig: two (2) tablet po daily (daily). disp:*60 tablet(s)* refills:*2* 4. trimethoprim-sulfamethoxazole 80-400 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. mycophenolate mofetil 500 mg tablet sig: two (2) tablet po bid (2 times a day). disp:*120 tablet(s)* refills:*2* 6. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 7. prednisone 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 8. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 9. oxycodone 5 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed. disp:*60 tablet(s)* refills:*0* 10. valsartan 160 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 11. tacrolimus 5 mg capsule sig: one (1) capsule po twice a day. disp:*60 capsule(s)* refills:*2* 12. tacrolimus 1 mg capsule sig: three (3) capsule po twice a day. disp:*180 capsule(s)* refills:*2* discharge disposition: home discharge diagnosis: liver transplant discharge condition: good discharge instructions: please return to the nearest emergency department or call the transplant coordinator () should you have a temperature greater than 101.5, abdominal pain, nausea, vomiting, shortness of breath, chest pain, excessive drainage or redness surrounding surgical incision. you will need labs (cbc, chem 10, lfts, coags, fk levels) drawn on either tuesday () or wednesday (). these results must be faxed to the transplant coordinator . you have been prescribed a study drug - you have received an educational session by the transplant team. followup instructions: provider: , md, phd: date/time: 3:00 provider: , md, phd: date/time: 2:20 provider: ,chair one rooms date/time: 8:15 md, procedure: other transplant of liver transfusion of packed cells other immobilization, pressure, and attention to wound other operations on lacrimal gland transplant from cadaver diagnoses: unspecified essential hypertension cirrhosis of liver without mention of alcohol chronic hepatitis c without mention of hepatic coma osteoporosis, unspecified other ascites malignant neoplasm of liver, primary
