Subcapsular hematoma and rupture of the liver graft
Abstract
Absztrakt
Májtranszplantáció után a graft subcapsularis haematomája és/vagy rupturája, mely kialakulhat spontán, sérülés vagy invazív radiológiai beavatkozásokat követően, ritkán előforduló, súlyos szövődmény. Szerzők 350 májátültetés során észlelt négy esetből három ismertetésével illusztrálják a szövődmény súlyosságát. Az első esetben graftbiopszia utáni álaneurysma halálos kimenetelű májrupturát eredményezett. A második esetben a donormáj felszínes sérülésének transzplantáció után mély ruptura lett a következménye, amely miatt májresectiót kellett végezni. A beteg septicus állapotban meghalt. A harmadik beteg műtét során észlelt subcapsularis haematomáját sikeresen kezelték, és a beteg meggyógyult. Eddigi tapasztalataik és az irodalmi ajánlások alapján a szerzők javaslatot fogalmaznak meg a műtét során keletkező májtok alatti vérömlenyek kezelésére, melynek lényegi részét képezi az argon-diathermia és a fibrinogennel és thrombinnal bevont kollagénszivacs alkalmazása.

Spontaneous hepatic rupture secondary to severe pregnancy-induced hypertension is associated with a high rate of maternal and fetal mortality. Numerous types of surgical management have been described, but a uniform surgical approach has not been accepted. The purpose of this review was to examine modes of surgical therapy reported in the literature since 1976, as well as the 11-year experience at our institution. Twenty-eight cases were extracted from the literature and seven more were identified at our institution. The incidence in our population was one per 45,145 live births. Among 27 cases managed by packing and drainage, an 82% overall survival was achieved, whereas only 25% of eight patients undergoing hepatic lobectomy survived (P = .006). Hepatic hemorrhage with persistent hypotension unresponsive to blood products should be managed by evacuating the hematoma, packing the damaged liver, and draining the operative site. More aggressive surgical techniques, such as hepatic artery ligation or hepatic lobectomy, should be reserved for refractory cases.
Spontaneous hepatic rupture associated with preeclampsia is a rare but life-threatening situation. Several different surgical treatments have been described, depending on the severity of the rupture. Liver transplantation has become the mainstay for patients with end-stage liver disease. Transplantation in the setting of liver trauma or massive parenchymal disruption is not well defined. To our knowledge, this treatment has not been reported for spontaneous hepatic rupture in pregnancy.
Massive, spontaneous hepatic rupture occurred in a patient at 36 weeks' gestation as a result of severe preeclampsia. Conventional surgical therapies were unsuccessful in controlling the massive hemorrhage. As a life-saving measure, the patient underwent total hepatectomy with the creation of an end-to-side portcaval shunt, thereby rendering the patient anhepatic. The patient was listed as urgently needing a liver for transplantation through the United Network for Organ Sharing. A suitable donor liver was located approximately 8 hours after the emergency hepatectomy. The patient underwent orthotopic liver transplantation after being maintained in an anhepatic state for almost 13 hours. The patient was discharged on postoperative day 41, suffering only from some ischemic lower extremity neuropathy secondary to hypovolemic hypotension occurring during the hepatectomy procedure.
In the reported case, spontaneous hepatic rupture resulted in a massive hemorrhage that could not be controlled by previously reported techniques and required total hepatectomy followed by liver transplantation.
From 1983 to 1991, 42 patients were operated on for hepatocellular carcinoma (HCC) complicating cirrhosis. Five presented with spontaneous rupture of the tumour: three had posthepatitis B and two non-A non-B cirrhosis. By contrast, 65 per cent of patients with non-ruptured HCC had alcoholic cirrhosis (P < 0.01). Laparotomy was carried out on an emergency basis (four patients) or after a 12-h delay (one) because of haemodynamic instability. Liver resection was performed in four cases (two wedge resections, one segmentectomy III, one extended right hepatectomy) and in the fifth patient hepatic artery ligation was performed. Bleeding was controlled after all four resections with one postoperative death, while the patient treated by ligation died during operation. Of the three surviving patients after liver resection, two died, 6 and 12 months after surgery. One patient is alive with recurrent tumour 43 months after extended right hepatectomy. The present data, combined with analysis of 250 cases of ruptured HCC from the literature, indicate that emergency resection is the treatment of choice in patients with limited tumour and preserved liver function. Transcatheter hepatic artery embolization, if available, is the next choice for high-risk patients or before surgical resection of the tumour. More conservative surgical approaches are the last choice because of poor reported results.
To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).
Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.
The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n = 3) or by arteriography (n = 4).
Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%).
As more adults undergo transplantation with partial liver grafts, the unique features of these segments and their clinical significance will become apparent. A patient presented with life-threatening hemorrhage from an iatrogenic laceration to a right lobe graft 11 days after transplantation. The creation of a portacaval shunt effectively controlled the bleeding, allowing more elective replacement of the organ with another right lobe graft. The regeneration process combined with increased portal blood flow and relative outflow limitation may have set the stage for this complication. Any disruption of the liver parenchyma during transplantation should be securely repaired and followed cautiously. Portacaval shunting is an option for controlling hemorrhage from the liver in transplant recipients. The timely availability of a second organ was likely the ultimate determinant of survival for this patient.
Spontaneous rupture of the liver has been described in association with many benign and malignant conditions. We report, to our knowledge, the first case of spontaneous rupture of the liver upon revascularization, requiring total hepatectomy and portocaval shunt, followed by successful retransplantation. Routine pathological examination of the explanted liver failed to reveal the etiology of the rupture. However, electron microscopy demonstrated abnormal collagen in the hepatic arterial wall compatible with a collagen disorder such as Ehlers-Danlos type IV disease. We conclude that the donor liver had a previously undiagnosed collagen disorder. Review of the literature does not preclude the use of livers from donors with a history of connective tissue disorders. Based on our experience one should exercise caution when using livers from such donors. With a history of connective tissue disorder in an immediate family member, further tests should be performed in the donor to rule out a subclinical connective tissue disorder. In addition, a review of all patients reported thus far to have undergone total hepatectomy and portocaval shunt, followed by liver transplantation as a two-stage procedure is presented.
Subcapsular liver hematoma formation has been reported in less than 2% of pregnancies complicated by HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. The purpose of this study was to identify the main diagnostic and therapeutic options for management of these patients.
In this 10-year retrospective review, we performed a computer-directed search of all cases of confirmed HELLP syndrome with hepatic hematoma treated in the surgical department of our tertiary care referral medical center.
Five patients with subcapsular liver hematoma in HELLP syndrome could be identified. All patients received transabdominal ultrasound, computed tomography, or magnetic resonance imaging. Conservative treatment was successful in three patients. Emergency surgical intervention was necessary in two patients, including one liver transplantation.
The case series shows the full diagnostic spectrum with transabdominal ultrasound, computed tomography, and magnetic resonance imaging, as well as the different therapeutic options varying from conservative therapy to operative management, including liver transplantation.
Subcapsular hematoma of the graft is an underreported complication of liver transplantation (LT). Among 408 LT performed from September 1, 1985, to September 1, 2000, eight patients developed a subcapsular hematoma within 30 days after LT (8/408 = 2.0%). Among the six early cases observed, five required further surgical approaches due to hematoma progression, rupture, and hemorrhage. One patient underwent liver retransplantation due to uncontrollable hepatic hemorrhage. The two more recent cases were successfully treated by early opening of the Glisson's capsule with hemostasis of the hepatic raw bleeding surface. The five patients who developed acute renal failure required dialysis. Three patients died during hospitalization. Among the survivors, two were discharged on the postoperative (PO) day 15; the others on PO day 37, 38, and 56. In conclusion, subcapsular hematoma of the graft is a potentially serious complication of LT that may produce severe hemorrhage, shock, and in extreme cases, graft loss or even death. The severity of the complication is related to the extension of the decapsulated area of the graft. An early surgical approach with intentional opening of the hematoma before progression of the lesion seems to facilitate hemostasis and improve results.
Subcapsular hematoma of the graft is a serious complication of liver transplantation (LT), and there has been no discussion in the literature about optimal management except in sporadic case reports. The aim of this work is to review our experience of subcapsular hematoma in living donor liver transplantation (LDLT) and to introduce our management strategy. Among the 818 cases of adult-to-adult LDLT between February 1997 and November 2005, there have been 4 cases of subcapsular hematoma. Two of these developed after percutaneous liver biopsy and the other 2 developed after percutaneous transhepatic biliary drainage (PTBD). Two developed immediately after the procedure, whereas the other 2 developed 8 and 12 days after the procedure, respectively, due to rupture of a pseudoaneurysm. Our management strategy was as follows; after performing dynamic computed tomography for initial diagnosis, these 3 steps were taken: 1) hepatic arteriography and selective embolization of bleeding focus; 2) pigtail catheter drainage (PCD) of subcapsular hematoma; and 3) hepatic vein stenting if there was a sign of outflow disturbance due to compression by a large hematoma. All 4 of our patients recovered from the insult of subcapsular hematoma. In conclusion, our results indicate that patients who develop subcapsular hematoma after LDLT can be treated nonsurgically.
