T. J. A IS STRONG PROPENSITY FOR T. E COMPLICATION THAT IS POTENTIALLY LIFE - THREATENING DVT
OBESITY CANCER PREVIOUS VTE FAMILY HISTORY SMOKING ADMISSION TO ICU DEHYDRATION THROMBOPHILIA CONTRACEPTIVE USE POST- OPERATION IMMOBILITY RISK- FACTORS
CHARNLEY & CO: 7959 CASES OF T. J. A 1962- 73 P- E : 8% FATAL CONDITION: 1% INSALL INCREASE ATTENTION TO T. E DISEAS AND EMPHASIS PREVENTION
DVT WITHOUT ANY PREVENTION 84%CLINICALLY P. E 1.7%FATAL P. E: - POSITIVE VENOGRAPHY NOT ITSELF ASSOCIATED WITH LOCAL SYMPTOMS
PRESENTATION OF T. E DISEASE FOLLOWING T. H. A & T. K. A IS DIFFERENT RELATED TO VIRCHOW’S TRIAD STASIS INTIMAL INJURY HYPERCOAGULABILITY
BEFORE ROUTINE USE OF CHEMOPROPHYLAXIS PROXIMAL DVT WAS IN 50- 60% OF T. H. A DISTAL WAS IN T. K. A
PROXIMAL THROMBI ALMOST IS SEGMENTAL AND NEAR LESSER TROCH LARGE MORE EMBOLIZE GREAT HEMODYNAMIC IMBALANCE MORE P. E RESULT
RESULT OF INTIMAL DAMAGE TO FEMORAL VEIN WHICH IS TWISTED DURING POSITION OF L- L PREPARATION & DEVICE INSERTION
POTENT ANTICOAGULANTS MITIGATE INTIMAL INJURY & REDUCE PROXIMIL THROMBI IN T. H. A DISTAL THROMBI AFTER T. K. A IS MORE RELATED TO BLOOD STASIS 1- FOLDING 3- OCCLUSION TOURNIQUET & ANTIGOAGULANT AND IPC ALONE ARE NOT EFFECTIVE IN PREVENTION OF POPLITEAL VEIN
PREVENTION WITH IPC AND REGIONAL ANESTHESIA OR IPC + CHEMOPROPHYLAXIS
RELEAS OF THE TOURNIQUET AFTER T. K. A TRANSESOPHAGEAL ECHOCARDIOGRAPHY HAS NOISE IN ECHO PATTERN FROM: 1- EMBOLIC 2- BONE MARROW 3- ELMENTS FAT
FAT FROM AFTER INTRAMEDULLARY CANAL INTRAVASATION CANAL PREPARATION PRESSURIZATION ON STEM CEMENTATION
ORTHOPEADIC SURGEON EMPHASIS TO: 1- PROPHYLAXIS OF CLINICAL EVENTS 2- BALANCE THE RISK OF BLEEDING MORE THAN: PREVENTION OF VENOGRAPHIC DISEASE
AMERICAN COLLEGE OF CHEST- PHYSICIAN (ACCP) SUGESST THAT ANTICOAGULANT NEEDED AS SOON AS ELEVATED BLEEDING RISK SUBSIDE
REGIONAL ANESTHESIA REDUCE DVT VASODILATATION BETTER VENOUS RETURN RESEMBLE OF SYMPATHECTOMY NO EFFECT ON INTRAOPERATIVE THROMBOGENIE BUT VASODILATION STIMULATE OF INTIMAL FIBRINOLYSIS PREVENTION OF DVT SPINAL EPIDURAL PROXIMAL CLOT 50% DISTAL CLOT 20%
2- PNEUMATIC COMPRESSION: - I. P. C ALONE IS NOT VERY EFFECTIVE - I. P. C & REGIONAL ANESTHESIA HAS SYNERGIC EFFECT TO PREVENT OF DVT
WESTRICH & COLLEAGUES SUGGEST IPC AND HEPARIN REDUCE DVT THAT SIGNIFICANTLY BETTER THAN WARFARIN OR ASPIRIN
3- ASPIRIN OVERALL ANTIPLATELER ARE INEFFECTIVE ON THE VENOUS SIDE OF CIRCULATION
RESULT OF STUDY IN 12291 PATIENT WITH T. J. A THAT ANALYSIS MORTALITY AT 1-6W 2- 3 MON G:A L. MW. H- XIMELAGTRAN - FONDAPARINUX G:B REGIONAL ANESTHESIA WITH OR WITHOUT 1- HEPARIN 2- IPC 3- ASPIRIN G: C WARFARIN
EMPHASIS THAT MULTIMODAL ASPIRIN PROPHYLALY IS BETTER ASPIRIN: REDUCE P. E. (CLINICAL MANIFESTATION OF V.T) SPECIALLY USE WITH REG- ANES
ACCORDINGLY: THERE IS BOTH EVIDENCE AND MOMENTUM GROWING TO JUSTIFY A RANDMIZED CLINICAL TRIAL COMPARING ASPIRIN – WARFARIN AND NEWER AGENT IN CONJUCTION WITH REG – ANES FOR VT PROPHYLAXIS AFTER T. J. A
SYMPTOMATIC & FATAL P. T. E IS MORE IN T. H. A THAN T. K. A RESIDUAL VENOGRAPHIC PREVALANCE OF DVT HAS BEEN MORE AFTER T. K. A CHMOPROPHYLAXIS
THIS MEAN THAT PREVENTION OF DVT AFTER T. K. A IS MORE REFRACTORY TO BOTH TRADITIONAL AND CONTEMPORARY DRUG PROPHYLAXIS
L. M. W. H OR FRACTIONAL MORE BINDING TO ANTI- THROMBIN III THAN CONVENTIONAL HEPARIN SO MORE EFFECT TO DVT PREVENTION IN T. J. A
HEPARIN INDUCED THROMBOCYTOPENIA (HIT) AND DEVASTING COMPLICATION OF ALL FORM OF HEPARIN UNCOMMON 2.6 % IN CONVENTIONAL- H 0.2 % IN L. M. W. H
FONDAPARINUX IS SYNTHETIC PENTASACCHARIDE BIND ONLY TO THE ANTI - THROMBIN III HEPARIN SITE AND HAD NO RISK OF HIT
ENOXAPARIN PROPHYLAXIS POWER, REDUCE V.T RATES FROM 28% TO 6%
RIVAROXABAN IN 2011 APPROVED BY FOOD & DRUG ADMINISTRATION REDUCE OVERALL DVT & ALL CAUSE MORTALITY. RATE UNDER 7% (IN 3148 T. K. A) 31.4% REDUCTION COMPARED WITH ENOXAPARIN
RIVAROXABAN 1- NEED NO MONITORING 2- METABOLIZE IN LIVER 3- ONLY ORAL USE 4- 10 mg DAILY 5- NO BLEEDING EVIDENT MORE THAN ENOXAPARIN
V. T OF CALF MANAGE WITH 6 WEEKS PERIOPERATIVE OF WARFARIN • PROXIMAL DVT WITH 12 WEEK WARFARIN • P. E WITH 3- 6 MONTHS • THERAPEUTIC (INR 2- 3) WARFARIN AFTER INITIAL ANTICOAGULATION WITH L. M. W. H MORE RECENTLY IN THE ERA OF L. M. W. H, IMMEDIATE OUTPATIENT TREATMENT OF V. T HAS BECOME POPULAR TREATMENT
HOW EVER, IN POSTOPERATIVE PATIENT WITH A SBSTANTIAL ATTENDANT RISK OF BLEEDING, INITIATION OF ANTICOAGULATION AS AN INPATIENT FOLLOWED BY OUT PATIENT THERAPY AFTER ANTICOAGULANT DOSING AND INTENSITY HAVE BEEN STABILIZED IS A MORE PRUDENT APPROACH
JBJS 2013/ 1/1 15670 T. J. A 5- YEAR 90 DAY FOLLOWED NO DIFFERENCE BETWEEN ASPIRIN AND L. M. W. H IN: T. E COMPLICATION P. E MORTALITY CONFIDENCE INTERVAL MAJOR HEMORROGE
COMBINED MECHANICAL & DRUG FOR 10- DAY AFTER T. K. A IS MORE EFFECTIVE
MORE PATIENT OF ASPIRIN GROUP MORE RETURN TO THEATER FOR WOUND COMPLICATION
CHARNLEY & CO 2012 7959 T. J. A 11 YEARS 1- PE: 8% 2- FATAL CASES 1% IN T. J. A WITHOUT PROPHYLAXIS DVT 84% CLINICALLY P.E 1.7% FATAL CASE OVERALL: IPC + L. M. W.H IS BETTER OF IPC + ASPIRIN OR WARFARIN
