Shin N et al . BCS review World J Hepatol 2016 June
■ Large geographic variations even in Asia in the prevalence of HVOTO with IVC, or combined IVC and HV blocks.
■ NEPAL : A prospective survey spanning 3 years of admission to the Liver Unit of Bir Hospital in Kathmandu, disclosed that IVC OR COMBINED IVC BLOCKS accounted for 150 of 866 patients with liver disease (17.3%),
■ PGI CHANDIGARH : As a comparison, it took 14 years to collect 91 cases of IVC or combined block in a Liver Unit at PGI Chandigarh;
■ MADRAS MEDICAL COLLEGE: 13 years to collect 78 cases.
■ AIIMS, NEW DELHI : Of 825 patients admitted for portal hypertension in the years 1978–1992, 51 (6.2%) had IVC or combined block.
PATHOPHYSIOLOGY
Hepatic venous outflow obstruction
Increased sinusoidal &
portal pressure
Extravasation of fluid from
sinusoids
Ascites
Venous stasis and congestion
Hypoxic damage to hepatocytes
Hepatocyte necrosis (Centrilobular) l/t lobular collapse
Fibrosis, Nodular regenerative hyperplasia
Cirrhosis
■Liver injury becomes irreversible once there is Lobular collapse
■Diagnosis before lobular collapse will allow the sinusoids to be decompressed, with recoverable liver function
■Early diagnosis and treatment of sinusoidal congestion is important for good prognosis
PATHO-PHYSIOLOGY
ACUTE STAGE
– Portal vein becomes draining vein
– Increased hepatic
arterial flow
CHRONIC STAGE
– Necrotic areas replaced by fibrotic tissue
– Intrahepatic collateral vessels
– Heterogeneous
enhancement with a reticular pattern at the periphery of liver
■ Caudate lobe hypertrophy (50%)■ Portal vein obstruction - 10-20% ■ Asynchronous obstruction of hepatic veins – Hepatic veins – 66% (Usually two are blocked for disease to be clinically evident)– Isolated occlusion of IVC – 10%– Combined occlusion – 23%

IMAGING
■Role of imaging– Site of obstruction– Patency of HV, IVC, Portal vein (PV)– Details of vascular anatomy– Status of liver– Caudate lobe– Collaterals– Differentiates forms of BCS
Brancatelli G et al, Am J Roentgenol 2007
DOPPLER USG– First investigation of choice– Sensitivity & specificity > 85%
Bolondi L et al,Gastroenterology 1991– CD & pulsed Doppler : complimentary to Gray Scale.– CE-USG : superior to Gray scale & CD for
detection/characterisation of HV throbosis.Bolondi Gastroenterology 1991
HV patency and size/IVC ThrombosisIntrahepatic collaterals (90%) Prominent IRHV/ caudate vein (>2mm) The ability to demonstrate the reversal of flow direction may be
the most important superiority of Doppler imaging in comparison to contrast-enhanced cross-sectional methods .Reversed flow direction in the main portal vein
Caudate hypertrophy (Mean AP > 35 mm)
Thrombus in middle hepatic vein. (A) Color Doppler image shows no color signal in lumen (arrow), indicating obstruction of vessel. (B) In another patient, weak intraluminal color signals can be
identified consistent with non-occlusive thrombus. Note reverse flow (flow towards to probe) in lumen which is represented by red color.
Web in inferior vena cava. Sagittal sonogram of upper abdomen demon- strates echogenic web constricting inferior vena cava (IVC) at
subdiaphragmatic level.
Chronic thrombosis of right hepatic vein. Gray-scale sonogram shows right hepatic vein (RHV) as hyperechogenic cord-like structure (arrows).

Chronic thrombosis of right hepatic vein. Gray-scale sonogram shows right hepatic vein (RHV) as hyperechogenic cord-like structure (arrows).
Inferior RHV (A) Duplex Doppler reveals enlarged IRHV lying behind right posterior PV branch. The Doppler tracing in IRHV has
lost its normal triphasic appearance. (B) Postcontrast fat-suppressed in-phase gradient-echo MR image obtained in axial
plane in same patient as in (A) shows IRHV (arrow) draining into IVC at level of porta hepatis. Also note, enlarged veins of vertebral
plexus and veins of anterior and lateral abdominal wall.Caudate vein > 2 mm : BCS should be questioned.
Intrahepatic collaterals present in 90% of cases
US can be used as an appropriate guide to treatment and for surveillance after TIPS
placement.

LIMITATIONS OF SON0GRAPHY
■ Restriction from body habitus, ■ Intestinal gas or excessive ascites, ■ Failure to detect fresh thrombus in veins, ■ Failure to demonstrate patent veins within
congested or conversely, shrunken cirrhotic liver, ■ Failure to demonstrate retroperitoneal collaterals
unless they are hugely dilated, and ■ Operator-dependency.
CROSS SECTIONAL IMAGING■CT/MRI scan– Venous anatomy – patent IVC, PV, HV and non
visualisation of HV.– Caudate lobe hypertrophy (Fan shaped
enhancement)– Collaterals– Ascitis– Liver
– The overall accuracy of CT for detecting thrombosis has been reported as 50% .
– Not found to be useful in showing web in the IVC
• Necrotic areas• Altered parenchymal
perfusion pattern• Early homogenous central
enhancement• Delayed patchy
enhancement of periphery of liver
• Prolonged retention of contrast in the periphery
• Regenerative nodules
Ayse Erden European Journal of Radiology 2007
Inhomogeneous enhancement of liver. CECT reveals lobular and patchy
areas of enhancement separated by linear and
reticulated regions of relatively low density. This
appearance is probably due to stagna- tion of sinusoidal
flow. Also note wedge-shaped peripheral area of diminished attenuation in
right lobe. Parenchymal changes in BCS CECT shows
peripheral regions with low attenuation due to portal hypoperfusion (black arrows). Such areas are prone to
atrophy. Dilated veins of caudate lobe (white arrows) can also be
identified.
ACUTE BCS : sagittal (A) and coronal (B) computed tomographic images, with subtle thrombosis in the hepatic veins with nonopacification ( black arrow ) and a smooth liver contour. CHRONIC BCS : Prominent intrahepatic vessels can be seen (C) , ascitis, significant caudate hypertrophy ( D, white arrow ), and heterogeneous enhancement is seen with central hyper- and peripheral hypo-enhancement (E) .
MRI■ Preffered as a SECOND LINE OF INVESTIGATION ■ Particularly beneficial in the evaluation of the patients with non-
diagnostic ultrasonography ■ Liver morphology and regional perfusional disorders : similar to CECT.■ However, some parenchymal lesions such as
Benign regeneration nodules (>10 in no,<4 cm & hypervascular)
Hemorrhagic necrosis and Perfusion disorders :
characterized better with MR imaging than with a CECT■ Useful in differentiating regenerative nodules from HCC based on T2-
weighted signal characteristics ( Brancatelli et al, 2007 )
Benign regenerative nodules. Coronal MIP image obtained at
portal venous phase of MR angiography shows multiple
enhanced nodules of varying size throughout liver.
HCC in BCS : In-phase gradient-echo MR image obtained at late venous
phase demonstrates HCC with mosaic pattern. Note delayed
enhancement of its fibrous capsule (arrows) and hypointense thrombus material in peripheral branches of
right hepatic vein (parallel arrows).
■ ENHANCEMENT PATTERNSACUTE : Both early and late gadolinium-enhanced
MR images show diminished peripheral enhancement.
SUBACUTE : heterogeneously increased enhancement within the liver periphery
CHRONIC : Minimal enhancement differences (40% SHOW HOMOGENOUS ENHANCMENT)
Atrophy of the right lobe of the liver (especially the peripheral regions), hypertrophy of the left lobe and the presence of regenerative nodules and contour irregularities show the progression to
cirrhosis hypertrophy of caudate lobe is found in 60–87% of
all cases
MULTIPHASIC STUDIES WITH MR
ANGIOGRAPHY■ HA/PV system are examined along with HV-IVC with one injection of contrast material
■ Narrowing, stretching or distortions of arterial and portal vessels : structural changes in parenchyma.
■ In portal venous phase (second phase) of MRA, venous out flow obstruction can be inferred from the patchy enhancement of the liver.
■ Late venous phase imaging is necessary to visualize the patent HVs and intrahepatic venous collaterals.
■ Hepatic veins with sluggish flow may be missed if inadequate delay time is used.
■ Later phases of examination : Dilution of intraluminal contrast l/t diminishes contrast difference between the vessels and parenchyma Thus thin collaterals seen on sonography may be inconspicuous at MR angiography.
LOCATIONS OF EXTRA- HEPATIC COLLATERAL VEINS IN BCS :
Different from those seen in cirrhosis. 4 groups mainly in RPDeep and central tributaries of the systemic circulation
Ascending lumber veins, Vertabral venous plexus, Azygos and Hemiazygos veins) are the most frequent
collateralized routes.These vessels can be observed on MR angiography and CT in 36% and 32% of the cases, respectively Other collateral vessels : Left renal-hemiazygos pathway and inferior phrenic-pericardiophrenic veins
Collateral veins in BCS. (A) Coronal MR image shows (IVC) occluded in its hepatic portion. IRHV is prominent as an intrahepatic collateral whereas azygos vein (AV), hemiazygos vein (HV) and left inferior phrenic vein (LIPV) are noted as extrahepatic collateral vessels. A: aorta, SV: splenic vein, LRV: left renal vein, and SMV: superior mesenteric vein. (B) Inferior venacavogram confirms occlusion in IVC and presence of IRHV and LIPV as collaterals.
ADVANTAGES OF MRA OVER DOPPLER
■ No restriction from body habitus and intestinal gas; ■ Short examination time; ■ No operator-dependency; ■ Better anatomic orientation, and ■ Easy documentation of surgical portacaval shunt
patency and portal venous system. ■ It also offers the possibility to evaluate the
enhancement patterns of liver parenchyma.

Venogram of the IVC demonstrates compression of the intrahepatic portion of the cava ( A, black arrows ) during placement of a TIPS
( single black arrow ). Most often, one of the occluded veins can be cannulated, often
showing thrombus ( B, black arrow ). Further injection after accessing the hepatic vein may demonstrate
the classic “spiderweb” pattern of small, intrahepatic venous collaterals (C)
CONTEMPORARY ROLE OF VENOGRAPHYPlatform for interventional radiology procedures. ■ TIPS placement, ■ Catheter-directed thrombolysis, ■ Mechanical thrombectomy and ■ Balloon angioplasty, and ■ Recanalization of an occluded hepatic vein or
vena cava with stent placement.■ Transjugular liver biopsy. ■ Use of hepatic venography may be an essential
guide and road map for surgical therapy in BCS
Erdon, 2007 ; Kamath, 2006
ROLE OF LIVER BIOPSYNeed?■ Parenchyma may be affected unevenly ■ Exclusion of cirrhosis or severe fibrosis■ Feasibility of shunt■ Differentiates veno-occlusive disease & cirrhosis of other origin

■Treatment depends on the
causethe anatomic
characteristics and stage of liver diseasethe pace of the disease
■Underlying disorder can be found in 70% cases & multiple disorders can be present in 25%
■Early relief of obstruction may reverse parenchymal abnormalities and improves survival
■Remove the cause■Prevention of thrombosis extension ■Relieve the high pressure &
congestion in liver■Management of massive ascites
MANAGEMENT OPTIONS
■Medical therapy■Minimal invasive
interventions (MII)■Surgery (SHUNT AND NON
SHUNT SURGERIES)■Liver transplantation
Is this the sequence?

MEDICAL MANAGEMENT
Objectives (1) remove the cause of the venous thrombosis, (2) relieve the high pressure and congestion within
the liver, (3) prevent extension of the venous thrombosis, and (4) reverse the massive ascites.
MEDICAL MANAGEMENT ■Anticoagulants (Heparin/ warfarin)■Systemic thrombolytic therapy ■Management of ascites– Sodium restriction (<2gm/day)– Diuretic therapy– Therapeutic paracentesis■Management of hematologic disorders
■ Anticoagulants– Recommended routinely– Underlying prothrombotic state– Heparin/ warfarin – Improvement in prognosis
Zeitoun G et al, Hepatology 1999– No reports of severe bleeding
Janssen et al, J Hepatol 2003
■ Systemic thrombolytic therapy/Local Thrombolytic therapy
– No benefitSharma et al, J Hepatol 2004
- 1/3rd of patients were believed to have had a clinical response to treatment for periods of 2 months to 1 year.
■ Recent series from China, 12 or 13 patients had patent hepatic veins without recurrent thrombosis after a mean follow-up of 24 months. The one initial treatment failure was salvaged by repeat angioplasty
Zhang et al, 2013■ Tissue plasminogen activator (tPA) is the direct thrombolytic of choice by catheter
route
■PCV : ■Hydroxyurea, (should be started as soon
as the disease is discovered and continued for life).
Other treaments : serial phlebotomy, anagrelide, interferon alfa-2b, and ruxolitinib.
Whatever treatment regimen is used, the disease runs a benign course if treated early.
Dramatic responses to intravenous (IV) heparin therapy have been reported, although relapses have been common.
Hartmann et al, 1980
■PNH : Eculizumab
Medical therapy alone – Is it enough?
– 12/14 died within 6 months McCarthy PM et al, Arch Surg 1985

decreased luminal shunt diameter) – – 18-78%,
– Mostly in 1st year
SURGICAL MANAGEMENT■Surgical Options
– Decompressive surgical shunts– Radical membrane excision– Surgical Removal of Venous
Obstruction
LIVER TRANSPLANT
SURGICAL SHUNTS
■Pre-requisite– Reversible liver injury
■Indication– Technically difficult TIPS (massive
thrombosis)– Porta-caval pressure gradient > 10 mm Hg
■Difficult to compare different groups
– Surgical vs. medical or minimally invasive techniques
■ Retrospective■ Significant time bias■ Sick patients usually managed medically■ No prospective studies■ No/ small control group

– Side to side portacaval Shunt (SSPCS)
– Mesocaval shunt (MCS)– Splenocaval shunt (SCS)– Proximal splenorenal shunt (PSRS)– Distal splenorenal shunt (DSRS)
■IVC OCCLUSION INFRA-HEPATIC IVC TO RIGHT ATRIUM PRESSURE GRADIENT > 20MM HG
– Meso-atrial shunts (MAS)– Cavo-atrial shunt with SSPCS– IVC stenting before PCS/ MCS– Cavocaval transflow– Splenoatrial shunt– Splenojugular shunt– Mesojugular shunt
Portacaval shunt
Mesocaval shunt

■Valveless PV can act as an outflow tract l/t sinusoidal decompression.
■Side to Side anastomosis between PV & IVC
■Shunt patency depends on the pressure gradient between the high pressure portal system & the low pressure IVC
■Best patency rates ■Shunt blockage rate is -- 3% at 13
years
Measurement of pressures in the IVC and PV with a saline (spinal) manometer by direct needle puncture before performance of portacaval anastomosis. All portal pressures are corrected by subtracting the IVC pressure from the portal pressure. Pressures in the IVC and PV are measured again after completion of the shunt. B, IVC pressure. C, Free portal pressure. D, Hepatic occluded portal pressure, obtained on the hepatic side of a clamp occluding the portal vein. E, Splanchnic occluded portal pressure, obtained on the intestinal side of a clamp occluding the portal vein.
Pressure gradient at the end of surgery of > 50 mm of saline is unacceptable and revision may be required
PROBLEMS WITH PCS
■Portal vein thrombosis is an obvious contraindication
■Dissection at porta- subsequent technical difficulty at transplant
■Fulminant liver failure and decompensated cirrhosis- Liver transplant

Recurrence of BCS in the transplanted liver
■ BCS following LT with the piggyback technique is a well-described complication.
■ Reported incidence of 1–7% (more common after the piggyback technique).
■ However, two recent retrospective studies were unable to detect a difference in the rate of BCS between the piggyback technique and the standard technique.
■ Usually presents in the early postoperative period. (25% after first week)
■ Technical factors : inadequate graft size and use of two hepatic veins for the venous anastomosis.
■ The rate of BCS after construction of the venous anastomosis with two veins is 2.3% while the use of three veins decreases the rate to 0.7%.
■ Conventional piggy back technique vs the side-to-side variation of the piggyback technique : 2.4% vs. 0.7% respectively incidence of BCS.

Mural et al. Hepatology 2004
The 5-year transplant-free survival was 89%, 74% and 42% for class I, class II and class III
respectively. A possible weakness of this study is that it
excluded patients who underwent transplant.
■ The Rotterdam score : Excellent in predicting intervention-free survival, and no other variable could significantly improve its prognostic ability.
Rotterdam score is the best discrimination index for 3-month mortality in BCS and should be used to determine treatment urgency.

Which is the best surgery for Budd-Chiari syndrome: venous decompression or liver transplantation? A single-center experience with 50 patients.Ringe B, Lang H, Klinik fur Abdominal- und Transplantations, Hennover, Germany.
The optimal treatment of BCS is still controversial whether venous decompression or LT is superior.
► 50 patients treated between 1981 and 1993 was retrospectively analyzed.► 12 pts : PSS or local decompressive procedures, ► 43 cases(38+5) : LT , including 5 with previous conventional surgery. ► The overall mortality of 18 of 50 was concentrated within the early postoperative
period, with no patient lost after 1 year.► In the venous decompression group, the success rate was only 29%, and
treatment failure was closely related to the finding of cirrhosis or technical problems like vascular thrombosis.
► After LT, early complications were rejection, primary non function, or graft necrosis, and contributed significantly to the risk of sepsis.
► 30 of 43 liver recipients are currently alive, including 4 rescued after failed decompressive surgery, with 1- and 10-year survival of 69%, and excellent recurrence-free rehabilitation.
► ConclusionPatient selection plays a dominant prognostic role in the treatment of BCS.
