A case report of total abdominal hysterectomy resulting in acute thrombotic thrombocytopenic purpura with pancreatitis and hepatitis: complete resolution with plasma exchange therapy

Postsurgical thrombotic microangiopathy: Case series and review of the literature

OBJECTIVES

Describe the clinical presentation, treatment, and outcomes of postsurgical thrombotic microangiopathy (TMA).

METHODS

In this retrospective study, records of individuals diagnosed with TMA developing within 30 days of a surgical procedure at Mayo Clinic from 2000 to 2016 were reviewed. Available literature regarding postsurgical TMA was comparatively reviewed.

RESULTS

Twenty patients were diagnosed with TMA developing within 30 (median 6.5, range (1-28)) days) following a procedure. Preceding procedures included orthopedic (n = 4), vascular (n = 4), abdominal (n = 8), thoracic (n = 2), and other (n = 2). Review of the literature identified 65 patients with postsurgical TMA and cardiovascular procedures were the most common preceding surgery. The majority of patients in the current cohort and literature were treated with therapeutic plasma exchange (TPE). Among the evaluable patients in the current cohort, 100% demonstrated response to TPE; however, 25% required the addition of other therapy including eculizumab to maintain a response 80% of patients in the literature demonstrated a response to TPE.

CONCLUSIONS

Although rare, early recognition and treatment of postsurgical TMA can lead to good outcomes. More research is necessary to determine the underlying pathophysiology and optimal treatment for postsurgical TMA.

Postoperative thrombotic thrombocytopenic purpura

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening disease characterized by acute episodes of thrombocytopenia and microangiopathic hemolytic anemia occurring due to platelet and von Willebrand factor deposition and hyaline thrombi formation in arterioles and capillaries throughout the body, which results in organ ischemia. TTP can be idiopathic or secondary, and there are several causes of secondary TTP. There is a clinical syndrome resembling TTP that occurs after surgical procedures, so-called "postoperative TTP" (pTTP). In this review, the differential diagnosis, pathogenesis and clinical and laboratory features of pTTP, together with the treatment modalities and outcomes of the patients, are discussed. The pTTP is a diagnosis of exclusion, and disseminated intravascular coagulation, heparin-induced thrombocytopenia and medication-induced effects should be ruled out. As in classical TTP, patients with pTTP should be diagnosed and treated with therapeutic plasma exchange (TPE) as early as possible to reduce their morbidity and mortality. Although rarely seen, surgeons and physicians of all specialties should be alert to the possibility of pTTP, and since pTTP is a life-threatening event that usually can be treated successfully with TPE, especially when diagnosed early in its course, it is critical to recognize and treat pTTP promptly.

Thrombotic thrombocytopenic purpura: a case presenting with acute ischemic colitis

Thrombotic thrombocytopenic purpura (TTP) consists of the pentad of thrombocytopenia, hemolytic anemia, fever, neurologic abnormalities, and renal disease. We present a case report of acute TTP following a bout of ischemic colitis. This report reminds the clinician that ischemic colitis can be an atypical presentation of TTP. The prompt recognition and treatment of this disease process resulted in a good prognosis for our patient.

Life-threatening hemorrhagic shock after laparoscopic surgery: a case of postoperative thrombotic thrombocytopenic purpura

We report the successful management of a female patient who developed postoperative thrombotic thrombocytopenic purpura (TTP) after an uneventful laparoscopic oophorocystectomy. The patient underwent uneventful laparoscopic surgery for ovarian cystoma. One hour after completion of surgery, the patient suddenly went into shock, with her blood pressure dropping to 60/40 mmHg. Hemorrhage into the abdominal cavity with an estimated blood loss of 2,000 ml was confirmed by exploratory laparotomy. Initially, anemia and thrombocytopenia were attributed to blood consumption or disseminated intravascular coagulation (DIC). However, blood tests revealed evidence of hemolytic anemia, with fragmented erythrocytes observed on peripheral blood smear examination. Serum levels of lactate dehydrogenase, blood urea nitrogen, and creatinine were elevated. Based on the findings, postoperative TTP was suspected. High-dose steroids and plasma infusions were administered but proved ineffective. Plasma exchange was performed three times, resulting in resolution of postoperative TTP. TTP is an idiopathic disorder, known to be triggered by surgical trauma. Postoperative TTP is difficult to distinguish clinically from DIC because of its close similarity with the latter and subtle differences from other postoperative hematological complications. It is important to bear in mind the possibility of postoperative TTP in patients with unexplained hemorrhagic shock after uneventful surgery.

Thrombotic thrombocytopenic purpura after prophylactic cefuroxime axetil administered in relation to a liposuction procedure

Thrombotic thrombocytopenic purpura (TTP) or Moschcowitz's syndrome is characterized by platelet and von Willebrand factor (vWF) deposition in arterioles and capillaries throughout the body, which results in organ ischemia. The diagnostic pentad characterizing TTP consists of thrombocytopenia, microangiopathic hemolytic anemia (MAHA), fever, neurologic manifestations, and renal insufficiency. In terms of type, TTP can be either idiopathic or secondary. The causes of secondary TTP include pregnancy, infections, pancreatitis, collagen vascular disease, cancer, bone marrow transplantation, and drugs (including cephalosporins). Postoperative TTP has been reported after vascular surgery, renal and liver transplantations, and orthopedic, urologic, and abdominal surgical procedures. Therapeutic plasma exchange (TPE) therapy has reduced the mortality rates, but sometimes patients may have to receive immunosuppressive drugs including vincristine (VCR). This report describes a 42-year-old woman with TTP after prophylactic usage of cefuroxime axetil in relation to a liposuction procedure who was treated successfully with plasma exchange and VCR. The patient fully recovered after 17 TPEs and three doses of VCR. At this writing, her TTP still is in remission after 6 months of follow-up evaluation. To the authors' knowledge, this is the first report in the literature describing a patient with TTP after cefuroxime axetil administered in relation to a surgical procedure who was treated successfully with TPE and VCR.

Thrombotic thrombocytopenic purpura associated with severe acute pancreatitis in a context of decreased ADAMTS13 activity: a case report

Thrombotic thrombocytopenic purpura (TTP) is a severe multisystemic microvascular disease defined by the association of hemolytic anemia, thrombocytopenia, acute renal failure, fever, and neurological disorders. The pathophysiology has recently been elucidated by the discovery of a von Willebrand factor-cleaving protease (ADAMTS13) deficiency involved in platelet aggregation and ischemia. The association between TTP and acute pancreatitis (AP) has rarely been reported, described either as a cause or a consequence. The role of ADAMTS13 during AP is still unknown. We describe the case of a 41-year-old woman who developed a TTP, with decreased ADAMTS13 activity, associated with severe AP. Published cases of thrombotic microangiopathy associated with AP are reviewed. The pathophysiology, management, prognostic factors, and rationale for treatment are discussed. AP should be sought in patients with TTP presenting with abdominal pain. On the other hand, TTP should be considered in patients with AP and thrombocytopenia.

Acute postoperative thrombotic thrombocytopenic purpura following hysterectomy and lymphadenectomy for endometrial cancer

BACKGROUND

Thrombotic thrombocytopenic purpura (TTP) in the acute postoperative setting is a recently recognized syndrome that, similar to classic or idiopathic TTP, presents variably with microangiopathic hemolytic anemia, thrombocytopenia, fever, renal failure, and mental status changes. Though most reports of postoperative TTP are in conjunction with cardiac or vascular surgery, it has also been reported following orthopedic and abdominal surgeries.

CASE

We present a case of a 53 year-old female diagnosed with metastatic poorly differentiated endometrial cancer who developed TTP the day following her cytoreductive cancer surgery.

CONCLUSION

To our knowledge, this represents the first reported case of postoperative TTP following gynecologic cancer surgery. Because the presentation can be confused with other early postoperative complications, awareness of this syndrome is essential as initiation of plasmapheresis can be life-saving.

Post-appendectomy thrombotic thrombocytopenic purpura: a case report and review of the literature

Thrombotic thrombocytopenic purpura (TTP) is a syndrome characterized by microangiopathic hemolytic anemia and thrombocytopenia with varying degrees of renal dysfunction, neurologic signs and symptoms, and fever. Evidence has supported that a large proportion of cases of acquired TTP are due to the accumulation of ultralarge von Willebrand factor (vWF) multimers due to an acquired deficiency in the vWF cleaving protease, ADAMTS-13. TTP is rare in the post-surgical setting but is best described after cardiothoracic and vascular surgeries. We present a case of postoperative TTP first presenting with microangiopathic hemolytic anemia and thrombocytopenia 9 days after emergent appendectomy for a ruptured appendix. ADAMTS-13 and factor H levels returned normal and an ADAMTS-13 inhibitor was not identified. To our knowledge, this is the first case report of postoperative TTP after an appendectomy and the first report with correlative ADAMTS-13 data. Plasma exchange with fresh frozen plasma followed by cryopoor plasma, along with steroids resulted in eventual remission of TTP in our patient. Early postoperative diagnosis and aggressive management with consideration of initiation of plasma exchange is imperative to decrease the morbidity and morality associated with TTP.
