Ovarian vein thrombosis, with rare exceptions, is a puerperal process that often mimicks appendicitis but may be recognized only in retrospect as a source of continued pulmonary embolization. Ovarian vein thrombosis may also accompany septic pelvic thrombophlebitis and constitute a life-threatening problem. Ovarian vein thrombosis probably exists in a subclinical form as well, and the relative infrequency of reports of this entity attest to the lack of clinical recognition rather than to its clinical rarity. Most instances of ovarian vein thrombosis will respond to antibiotics, anticoagulation, hydration and bed rest but, when septic in etiology, interruption of the vena cava and ovarian veins may be required. Acute appendicitis, the most frequent misdiagnosis, often leads to exploration, and careful resection of the affected vein in such patients generally results in cure.

The authors report two cases of puerperal right ovarian vein thrombophlebitis (POVT) with floating thrombus in the inferior vena cava (IVC). The originality of this report lies in the first line surgical treatment approach. POVT is recognized as presenting usually within the first week post-partum after about 0.05% of deliveries. The syndrome consists of lower abdominal or flank pain, unexplained fever and a tender abdominal mass. Abdominal or pelvic findings are often scanty. In some cases, the thrombus may extend to the inferior vena cava, leading to the risk of pulmonary embolism or low grade renal insufficiency. Diagnosis has been difficult in the past. Since acute appendicitis is the commonest differential diagnosis, laparotomy is frequent. CT scan provides a readily available, accurate, non invasive technique for the diagnosis of POVT. Criteria are: enlargement of the vein, a low density lumen within the vessel wall and a sharply defined vessel wall enhanced by contrast media. The treatment of POVT is initially medical. Antibiotics should be given to cover the commonest infecting organisms. Heparin should also be prescribed at therapeutic IV doses to be followed by oral anticoagulants for at least six weeks. Surgery is usually only recommended when the patient remains symptomatic despite proper medical management, develops clinical, scan or arteriographic evidence of pulmonary embolism, or cannot be anticoagulated. The recommended surgical technique is to clamp the anastomosis of the ovarian vein with the vena cava.(ABSTRACT TRUNCATED AT 250 WORDS)

Common primary surgical sources of thrombophlebitis of the mesenteric vein are diverticulitis and appendicitis. This is an acute ascending infection with septic thrombophlebitis. C.T. imaging can diagnose this complication at an early stage. Broad spectrum antibiotic therapy and heparin should be started. Surgery is performed electively to eradicate the primary inflammatory process. Early detections of septic ascending pylephlebitis and adequate treatment have decreased the mortality rate. We report a clinical case of thrombophlebitis of the mesenteric vein in acute appendicitis.

Amoebiasis, a disease of worldwide distribution, is endemic in tropical countries with suboptimal sanitation facilities. Isolated amoebic appendicitis (IAA) is regarded as a rare manifestation of the disease globally. Because there are no defined clinical features that distinguish IAA from bacterial appendicitis, diagnosis is usually dependent on histopathological examination. A 9-year retrospective study was undertaken to investigate the clinicopathological aspects of IAA. The main complaints were fever and abdominal pain. None of the patients had dysentery. The pre-operative clinical diagnosis was acute appendicitis and acute abdomen in 13 and 8 patients, respectively. In all cases the intra-operative diagnosis was acute appendicitis. Gross pathological appraisal revealed peritonitis and perforation in 19 and 17 cases, respectively. Histopathological examination of these appendices demonstrated appendiceal ulceration, transmural mixed inflammation, haematophagous amoebic trophozoites and necrosis in all cases. Vascular pathology comprised venous and capillary luminal plugging (11 cases), necrotising small vessel vasculitis (11 cases), thrombophlebitis of medium sized veins (9 cases) and arteritis with associated thrombosis (1 case). Organising fibrinopurulent peritonitis was present in 19 cases. Two appendices that appeared normal macroscopically demonstrated ulceration and inflammation that were confined to the mucosa and submucosa. All of 18 patients who were treated with metronidazole survived without further surgery, while three patients who were untreated succumbed to the disease. Appendicectomy, accurate histopathological appraisal thereof and optimal, timely management of IAA were critical to the favourable outcome in the present study.

Pylephlebitis is extremely rare and associated with high mortality, even in this modern era. It usually occurs secondary to infection in the region drained by the portal systems or in the structure contiguous to the portal vein. We report a case of septic thrombophlebitis of the portal and superior mesenteric veins (SMV) with multiple liver abscesses caused by acute appendicitis with an abscess of the mesoappendix. We performed appendectomy and successfully removed the thrombi using a Fogarty catheter. Postoperative histopathological examination confirmed a diagnosis of appendicitis and septic thrombophlebitis of the portal vein and SMV. The patient recovered completely with appropriate medical and surgical treatment.

Pylephlebitis, a rare complication of acute appendicitis, is defined as thrombophlebitis of the portal venous system. Pylephlebitis usually occurs due to secondary infection in the region drained into the portal system. We report a case of pylephlebitis caused by acute appendicitis. The patient was transferred from a private clinic 1 wk after appendectomy with the chief complaints of high fever and abdominal pain. He was diagnosed with pylephlebitis of the portal vein and superior mesenteric vein by CT-scan. The patient was treated with antibiotics and anticoagulation therapy, and discharged on the 25th day and follow-up CT scan showed a cavernous transformation of portal thrombosis.

Pylephlebitis, a septic thrombophlebitis of the portal vein, is a life-threatening complication of intraabdominal infections, commonly associated with acute appendicitis in children, and diverticulitis in adults. A 13-year-old boy was admitted for high fever and jaundice. On the fifth day of hospitalization, ultrasound Doppler flow and Computer Tomography scan studies showed thrombosis of the portal vein and acute appendicitis. The patient was treated with antibiotics, anticoagulation and laparotomy with appendectomy. No thrombophilic risk factors were diagnosed. Our aim is to improve physicians' awareness of this complication and emphasize the importance of early diagnosis and appropriate therapy in children in order to reduce serious complications and long-term sequels.

Mesenteric venous thrombophlebitis represents a very rare complication of acute appendicitis. Based on the findings of a 45-year-old patient with mesenteric venous thrombophlebitis due to acute appendicitis, we herein describe the diagnostic difficulties and therapeutic options in this uncommon disease. The treatment in our case consisted of simple appendectomy and perioperative anticoagulation therapy.

Septic thrombophlebitis of the superior mesenteric vein (SMV) is rarely caused by acute appendicitis. The clinical symptoms of SMV thrombophlebitis are varied and atypical, so the diagnosis is commonly delayed, resulting in a reported mortality rate of 30%-50%. We report a case of SMV septic thrombophlebitis caused by acute appendicitis in which the patient was successfully treated with surgical intervention, appropriate antibiotics, and anticoagulation therapy. A follow-up abdominal computed tomography scan after 3 months of treatment showed that the SMV thrombosis had been resolved.

Pylephlebitis is defined as septic thrombophlebitis of the portal vein. It is a rare but serious complication of an intraabdominal infection, more commonly diverticulitis and appendicitis. It has an unspecific clinical presentation and the diagnosis is difficult. The authors report a case of a 21-year-old man with acute appendicitis complicated by pylephlebitis. The diagnosis was made with contrast enhanced CT.
