Chief Complaint & HPI
Chief Complaint
Bleeding right thigh mass in a patient being anticoagulated forpulmonary embolism
History of Present Illness
86yo Hispanic male with known history of metastatic pleomorpliposarcoma of the right thigh presents with a bleeding right thmass. On staging CT of the chest, there was an incidental PE
Anticoagulation was initiated with Lovenox to Coumadin bridgepatient returned with several days of persistent bleeding of theIR was consulted to assist with management.

Intervention
ObjectivesPrimary: Stop the bleeding from the thigh mass
Secondary: Prevent new PE or worsening of current PE
Plan
1. RBC transfusion for anemia
2. Hold Lovenox and Coumadin to resolve coagulopathy
3. Arteriogram of right lower extremity following access of left common fartery. Selectively embolize feeding vessels to the tumor.
4. Place IVC filter via the opposite groin or transjugular approach

Question 1
1) To significantly decrease operative bleeding of a soft tissue tumowhat percentage does tumor enhancement need to be reduced preoperative embolization?
A: 5%
B: >20%
C: >70%
D: >95%

Correct!
1) For preoperative embolization of a bone or soft tissue tumor to significdecrease operative bleeding, by what percentage does tumor enhanceneed to be reduced?
A: 5%
B: >20%
C: >70%. According to Sun and Lang, preoperative embolization must elim>70% of the arterial supply to the tumor in order to significantly reduce o
bleeding. According to Barton et al., surgical resection should occur withof the embolization to prevent neovascularization.
D: >95%

Question 2
2) Which of the following is an indication for IVC filter placement?

Correct!
1) Which of the following is an indication for IVC filter placement?
A: Treatment of acute pulmonary embolism. IVC filters are used to prevent PE in with lower extremity DVTs.
B: Prevention of pulmonary embolism in a patient who cannot be anticoagulatedfilter placement is indicated in patients who cannot be anticoagulated due to rectrauma or bleeding risk, and in patients who have failed anticoagulation therapy
C: To maintain patency of the IVC in a patient with intra-abdominal malignancy. IV
are not used to stent the IVC, but to prevent clot or debris from migrating to thepulmonary arteries.
D: Prevention of pulmonary embolism in a patient with upper extremity DVT. A fiINFERIOR vena cava, would not prevent an upper extremity DVT from migratinglungs.

Clinical Follow Up
Bleeding of the right thigh mass stopped POD#1 at whichanticoagulants were resumed.
Patient was discharged home on POD#4 to home healthc
Recommendations were to have outpatient radiation thethe right thigh to prevent future growth and revascularizathe mass.

Summary & Teaching Points
Embolization of bone and soft tissue tumors is well described in the literpreoperative conditioning and palliation. Our case is unique in that it reppalliative embolization for the specific purpose of decreasing bleeding in anticoagulated patient with an unresectable primary tumor.
Contraindications to bone and soft tissue embolization include coagulopthrombocytopenia and anemia. For this reason, we corrected the coaguand transfused PRBCs prior to the procedure.
IVC filter placement is an effective way to prevent PE in a patient withcontraindications to anticoagulation (as in this patient).
