Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty Using Surgical Interventions

BackgroudRecurrent hemarthrosis following total knee arthroplasty (TKA) is a rare complication. Its pathophysiology and standard treatments have not yet been established. In this study, we report 7 cases of recurrent hemarthrosis after TKA in which failure of the initial conservative treatment was followed by angiographic embolization; in 1 of the 7 cases, arthroscopic electrocauterization was also performed after treatment failure with selective embolization.MethodsFrom January 2015 to May 2018, 7 patients visited our hospital due to recurrent hemarthrosis after TKA. Their medical records and serologic test results were reviewed to check for the presence of any bleeding disorder and history of anticoagulant use. Implant malalignment and instability were checked using X-ray. In all cases, the conservative treatment failed, so interventional angiography with selective embolization was performed, which was also followed by arthroscopic electrocauterization if the outcome was unsatisfactory.ResultsThe interval between TKA and the onset of hemarthrosis ranged from 3 to 76 months (average, 34.1 months). There was no coagulopathy and instability. All patients underwent conservative treatment at an interval of 4.3 months and the rate of relapse was 3.1 on average. On the interventional angiography, 6 cases showed vascular blush, and 1 case had pulsatile bleeding. The average duration for interventional angiography was 90.9 minutes. The average length of follow-up was 38.8 months. Embolization was successfully performed in 4 cases. In 2 of 3 failed cases, the symptoms improved without further treatment. In the remaining 1 failed case, the patient had a relapse of hemarthrosis, so an arthroscopic procedure was performed, which led to identification of the suspicious bleeding point by using preoperative angiographic findings. Electrocauterization was performed and active bleeding was stopped. All cases with recurrent hemarthrosis achieved improvement.ConclusionsInterventional angiography was used to aid in the diagnosis of recurrent hemarthrosis, and therapeutic selective embolization provided satisfactory clinical results. Even if selective embolization fails, interventional angiography may be helpful for further surgical procedures because it reveals vascular blush of a bleeding site. Therefore, interventional angiography and selective embolization should be considered to be a useful treatment for recurrent hemarthrosis after TKA.     

Magnetic resonance angiography in the management of recurrent hemarthrosis after total knee arthroplasty

Spontaneous hemarthrosis is an infrequent but disabling complication after total knee arthroplasty. The purpose of this case series is to demonstrate the utility of magnetic resonance angiography (MRA) in the evaluation of hemarthrosis after total knee arthroplasty. Patients presenting with hemarthrosis unexplained by trauma, anticoagulation, or a bleeding diathesis were retrospectively identified. Eighteen patients were referred for MRA to evaluate recurrent hemarthrosis after failing conservative therapy (n = 16) or synovectomy (n = 2). Despite artifact caused by the metallic components, diagnostic evaluation of regional vessels was made. In 12 of 13 cases that underwent embolization or synovectomy, a hypertrophic feeding artery (or arteries) was visualized on MRA. One case of negative MRA did not have subsequent surgery, and we are unable to comment on the rate of false-positives because all patients in this case series had evidence of bleeding. By characterizing the vascular anatomy and identifying a dominant artery (or arteries) supplying the hypervascular synovium, MRA can serve as a guide for subsequent embolization or synovectomy, as indicated.     

Pseudoaneurysm of the Medial Inferior Genicular Artery After Anterior Cruciate Ligament Reconstruction

We present a case of pseudoaneurysm formation of the medial inferior genicular artery after anterior cruciate ligament reconstruction. The patient presented with repeated knee hemarthrosis. He was diagnosed by means of magnetic resonance angiography and was treated by means of transluminal embolization. The patient's normal was normal after resolution of the vascular pathologic condition.     

Recurrent hemarthrosis in a hemophilic patient after revision total knee arthroplasty

Recurrent hemarthrosis following a revision total knee arthroplasty is a rare complication. The likelihood of encountering bleeding complications in patients with hemophilia C following major surgery is unpredictable. Although the use of postoperative chemotherapeutic agents to prevent deep venous thrombosis (DVT) is considered the standard of care for most patients, its use in the hemophiliac population is unknown. This case describes a woman with Hemophilia C who presented with recurrent hemarthrosis 9 days after her revision total knee arthroplasty. Initial treatment efforts were directed towards treating the patient's underlying coagulopathy. Repeated transfusions of fresh frozen plasma and desmopressin were given in an attempt to achieve hemostasis. However the hemarthrosis did not resolve and 36 days postoperatively, a pseudoaneurysm of the left superior geniculate artery was found by angiography and percutaneously embolized. This article presents the first case, to our knowledge, of recurrent hemarthrosis in a hemophiliac patient after revision total knee arthroplasty. It further highlights the importance of considering all possible causes of postoperative bleeding to make a timely diagnosis in the face of a confounding clinical picture.     

Geniculate Artery Embolization in Patients With Recurrent Hemarthrosis After Knee Arthroplasty: A Retrospective Study

BackgroundRecurrent hemarthrosis after knee arthroplasty is an uncommon and disabling complication of this frequently performed procedure. Selective endovascular embolization of the geniculate arteries is one of the therapeutic options to manage this complication. The purpose of this study is to analyze the effectiveness of this treatment in patients suffering from recurrent hemarthrosis after knee arthroplasty.MethodsWe performed a retrospective study of 31 patients (39 embolization procedures) with recurrent hemarthrosis after knee arthroplasty. There were 17 men and 14 women with a median age of 67 years (range 48-90). All patients were referred for geniculate artery embolization between January 2007 and November 2016.ResultsTwenty-seven procedures were executed on the right side and 12 on the left side. Total knee arthroplasty was performed on 29 patients, only 2 patients underwent unicompartmental knee arthroplasty. Embolization of the superior geniculate arteries was achieved in all patients. In 12 of 39 procedures (31%), at least 1 of the inferior geniculate arteries could not be catheterized, therefore embolization was achieved through collaterals. Symptomatic improvement was observed in 26 of 31 patients (84%). Discomfort or mild postprocedural pain was observed in most patients, needing only minor pain medication, mostly resolving within 24 hours. Two patients presented with a severe complication: a 48-year-old male patient developed septic arthritis and an 85-year-old hypertensive female patient treated with anticoagulants showed aseptic necrosis of the femoral condyles.ConclusionEmbolization of geniculate arteries is a safe and effective treatment in recurrent hemarthrosis post knee arthroplasty. Clinical improvement was seen in most patients.     

Recurrent hemarthrosis following total knee arthroplasty. Report of a case treated with arterial embolization

Recurrent spontaneous hemarthrosis of the knee is common and often related to a detectable cause. In contrast, hemarthrosis after knee arthroplasty is rare and frequently unexplained. We report a case of recurrent hemarthrosis 6 years after total knee arthroplasty. The cause was hypervascularization about the joint, and embolization therapy was effective.

Recurrent hemarthrosis after unicompartmental knee arthroplasty

Recurrent hemarthrosis after knee arthroplasty can be disabling, requiring adequate and immediate diagnosis and treatment for recovery of symptoms and joint function. The most commonly reported cause is impingement of proliferative synovium between prosthetic components. Although various procedures for hemarthrosis have been reported after knee arthroplasty for patients who do not respond to conservative treatment, the recommended first-line therapy is open surgery or embolization. Although hyperplastic synovium was observed during the first and second arthrotomy, in our case, tissue impingement was not detected. We describe a rare case of recurrent hemarthrosis after unicompartmental knee arthroplasty (UKA) and successful treatment by open synovectomy. A 66-year-old woman presented with spontaneous osteonecrosis of the medial femoral condyle in the right leg. She underwent UKA of the right knee of the medial condyle. Eighteen months after UKA, the patient developed recurrent hemarthrosis. Open arthrotomy was performed 22 months after UKA, revealing only hematoma with no obvious hemorrhage or loosening of the prosthesis. No history of trauma or use of anticoagulant medications was present. After a symptom-free period of 8 months, another 2 episodes of hemarthrosis occurred over the course of 8 months. A second open arthrotomy was performed. Hyperplastic synovium with fibrin and hemosiderin pigmentation was observed, again without hemorrhage or loosening. There were no pathological features of pigmented villonodular synovitis. Synovectomy was performed, and no hemarthrosis has recurred for 2 years.     

Therapeutic embolization of the genicular arteries for recurrent hemarthrosis after total knee arthroplasty

The case of a recurrent hemarthrosis initially presenting 30 months after a total knee arthroplasty in a patient on lifelong warfarin is described. Angiography was used to aid in the diagnosis, and therapeutic selective embolization of the superior genicular arteries was performed with satisfactory clinical results.     

Superior medial geniculate artery pseudoaneurysm after primary total knee arthroplasty

Vascular complications after total knee arthroplasty are rare. To date, there are 7 reported cases of pseudoaneurysms affecting the popliteal artery and 6 cases affecting one of the geniculate arteries. We present a case of a geniculate artery pseudoaneurysm that shared symptoms of a deep venous thrombosis on physical examination of a patient who underwent primary total knee arthroplasty. To date, there are no reports in American literature of pseudoaneurysms affecting the superior medial geniculate artery after primary total knee arthroplasty. After a vascular workup including computed tomographic angiography, surgical management included evacuation of the pseudoaneurysm and ligation of the feeding artery. The patient went on to successful recovery.     

Interventional Therapy for the Treatment of Severe Hemobilia After Percutaneous Transhepatic Cholangial Drainage: A Case Series

From May 2003 to May 2010, a total of 9 patients with severe hemobilia after percutaneous transhepatic cholangial drainage (PTCD) were diagnosed using superselective angiography and cholangiography, and then were treated with interventional procedures. Two patients with hepatic arterio-biliary fistula underwent proximal and distal arterial embolization of the responsible vessel. Six patients with pseudoaneurysm had pseudoaneurysm occlusion with proximal and distal embolization. Another patient with biliary-portal vein fistula received a biliary fully covered stent placement. The effects in these patients were evaluated using superselective angiography immediately after the intervention and at 3- and 6-month follow-up. In all patients, hemobilia was stopped right after the treatment and no sign of recurrence was noted at 3- and 6-month follow-up after the interventional therapy. Our findings demonstrate that interventional therapy is a simple, minimally invasive, and safe approach for treating severe hemobilia in patients receiving PTCD.

Pseudoaneurysm of the Superior Pancreaticoduodenal Artery,a Rare Cause of Hemosuccus Pancreaticus: Report of a Case

Chronic pancreatitis with a pseudoaneurysm is an established cause of hemosuccus pancreaticus. We herein describe a patient with chronic alcoholic pancreatitis associated with hemosuccus pancreaticus due to a pseudoaneurysm of the anterior superior pancreaticoduodenal artery rupturing in a pseudocyst of pancreas in the head region. Angiographic embolization was unsuccessful and therefore a laparotomy, ligation, and excision of the pseudoaneurysm with external drainage of pseudocyst were performed. Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding. Contrast-enhanced computed tomography and angiography is diagnostic in the majority of the cases. Surgery is the treatment of choice. Selective angiographic embolization may be helpful in tiding over the emergency until surgery can be performed.     

Pseudoaneurysm of the distal thigh after manipulation of a total knee arthroplasty

The authors describe a unique complication after manipulation of a stiff total knee arthroplasty in a 47-year-old man. Four days after undergoing manipulation under anesthesia (MUA), the patient presented with increasing pain and swelling of the affected knee and decreased hemoglobin/hematocrit. Computed tomographic angiogram revealed a ruptured pseudoaneurysm of a segmental branch of the deep femoral artery that was treated with embolization and anterior thigh compartment fasciotomy. Although many complications of MUA have been described, we present a novel finding of a ruptured pseudoaneurysm. Ruptured pseudoaneurysm should be included in the differential diagnosis whenever a patient presents with pain and swelling of the thigh after MUA given its potential morbidity.     

Therapieoption perioperativer Blutungskomplikationen

Perioperative hemorrhage after total hip arthroplasty is a rare but life-threatening complication. The aim of the current retrospective analysis of five cases was to answer the question of whether bleeding can be controlled by angiography and catheter embolization.A retrospective analysis of five patients with perioperative bleeding complications after hip surgery was done. Bleeding occurred in one case after implantation of an acetabular revision cup, in three cases in association with implantation of a bipolar prosthesis, and in one case in conjunction with a Girdlestone procedure due to septic femoral head necrosis. In four cases we detected arterial bleeding with angiography, all of which were controlled during angiography; one case was complicated by bleeding after a few days. One patient died from multiorgan failure after control of peracute hemorrhage.Subacute hemorrhage after hip surgery can be controlled by angiography. In peracute situations clamping of the external iliac artery is an alternative procedure.     

Transarterial endovascular coil embolization in managing intractable bleeding from fibular artery: A case report

IntroductionPseudoaneurysms of the fibular artery are rare. Recently, endovascular techniques have been preferred over open surgery.Case presentationA 50-year-old male patient complained of recurrent bleeding from surgical wounds that had been present for one month. The patient sustained an open cruris fracture. No source of active bleeding was found at the time of exploration. The patient has then performed angiography with coiling and showed a pseudoaneurysm originating from the left fibular artery branch. Surgical debridement and external fixation were performed one day after the angiography and embolization procedure. The patient was discharged on the third day, and there has been no recurrent bleeding ever since.Case discussionA pseudoaneurysm can be thought of as one of the intractable bleeding causes. Recently, the endovascular technique has been commonly used as an alternative treatment if we did not find the source of bleeding in exploration. Many kinds of the literature showed the success of using non-surgical management, especially the coil embolization as the patient received.ConclusionIn the management of pseudoaneurysm following trauma which cannot be found in open surgery, an endovascular technique like coil embolization can be the alternative method.     

Femoral nerve palsy associated with iliacus hematoma following pseudoaneurysm after revision hip arthroplasty

Iliacus hematoma associated with femoral nerve palsy is a very rare but considerable complication of hip arthroplasty. A 76-year-old woman had femoral nerve palsy 6 months after revision hip arthroplasty using a reinforcement plate. Computed tomography and selective angiography revealed the pseudoaneurysm on an extension of one of the screws fixing the hardware. Transcatheter arterial embolization proximal to the aneurysm was performed to resolve the aneurysm and to prevent further bleeding. Surgical removal of the hematoma was successfully achieved, as was full functional recovery. This case report describes our diagnosis and treatment of this rare condition and also the therapeutic usefulness of the radiologic intervention to control further bleeding before and after surgical removal of the hematoma.     

Relationship between pseudoaneurysm formation and biloma after successful transarterial embolization for severe hepatic injury: permanent embolization using stainless steel coils prevents pseudoaneurysm formation

OBJECTIVE: The purpose of this study was to determine the association between bilomas and pseudoaneurysm complications after severe hepatic injury. METHODS: Angiography was performed in patients with American Association for the Surgery of Trauma grade > or = III hepatic injury on contrast-enhanced computed tomographic scanning. When contrast extravasation was observed, transarterial embolization (TAE) was performed. After TAE, technetium-99m pyridoxyl-5-methyl-tryptophan cholescintigraphy was performed to detect the coexistence of bilomas. Follow-up angiography was performed when a biloma was detected. Eighty consecutive patients underwent angiography; after angiography, five patients died. The remaining 75 patients who underwent cholescintigraphy were included in this study. RESULTS: All 11 patients who had bilomas had angiographic evidence of contrast extravasation. The biloma frequency was higher in patients with grades IV and V injuries than in those with grade III injury (p = 0.024). Follow-up angiography revealed pseudoaneurysms in 7 of these 11 patients. All six patients in whom only gelatin sponge pledget injection was used to embolize had pseudoaneurysms. Among them, two patients had computed tomographic evidence of massive intra-abdominal fluid collection. In contrast, only one of five patients who received the combination of gelatin sponge pledget injection and stainless steel coils to permanently embolize injured arteries had a pseudoaneurysm. In this patient, the pseudoaneurysm was found in the peripheral part of the collateral vessels. All patients with pseudoaneurysms underwent repeat TAE and were discharged from the hospital uneventfully. CONCLUSION: In patients with high-grade hepatic injury and arterial bleeding who developed biloma, use of a gelatin sponge, an absorbable embolic material, is associated with a risk of pseudoaneurysm formation. Permanent arterial embolization using stainless steel coils is indicated to decrease this risk.     

Giant pseudoaneurysm of posterior division of renal artery: A rare complication of pyelolithotomy

Giant renal artery pseudoaneurysm after pyelolithotomy is an uncommon but important disorder. A case of giant pseudoaneurysm arising from the posterior division of right renal artery following pyelolithotomy is presented. The patient presented with a flank mass six months after pyelolithotomy. CT-scan as well as selective renal angiography revealed a giant pseudoaneurysm arising from the posterior division of renal artery. Nephrectomy was necessitated as selective embolization was not possible due to its extraordinarily large size. This revised version was published online in September 2006 with corrections to the Cover Date.     

Recurrent hemarthrosis after knee joint arthroplasty: etiology and treatment

This study reports the results for 10 patients with recurrent hemarthrosis after knee joint arthroplasty. The average interval between arthroplasty and the first instance of hemarthrosis was at 26 months, and the average number of hemarthroses per patient was 3.8. In 3 patients, the bleeding responded to simple conservative measures. The remaining 7 needed surgery; there were 6 arthroscopic synovectomies and 1 polyethylene revision. Impingement of the proliferative synovium was observed in only 2 patients during surgical intervention. In the 2 patients in whom arthroscopic management was successful, another procedure with an electric coagulator, in addition to a formal synovectomy, was performed. The use of a coagulator may be helpful for direct coagulation when arthroscopic management is selected, although open synovectomy is curative in most cases.
