A case report of mesenteric venous thrombosis with small bowel infarction in a 38-year-old woman who had been taking oral contraceptives is reported. The patient was admitted complaining of severe abdominal pain and vomiting for 36 hours. On admission, temperature was 37.5 degrees C and pulse 120/minute. Abdominal rigidity and left-sided abdominal tenderness were present. X-ray of the abdomen showed 2 distended loops of small bowel and 3 fluid levels. Serum amylase was normal. White cell count was 10,000/cu mm. There was a history of abdominal pain and diarrhea over a period of several years. For 6 months she had been taking Ovulen (mestranol .1 mg and ethynodiol diacetate .5 mg) for menstrual irregularity. 2 weeks earlier she had suffered an influenzalike illness with pleuristic chest pain, loin pain, urinary frequency, and dysuria. Chest X-ray and intravenous pylography were then reported as normal. At immediate operation, a 15 cm segment of ileum was found to be infarcted. Semipurulent fluid was present in the abdomen and areas of fibrinous peritonitis were observed. The involved segment of ileum was resected. A small thrombus was extracted from a mesenteric vein. Initial postoperative course was good but 3 days after operation chest pain, dyspnea, and giddiness developed and cardiac arrest followed. Resuscitation was successful. Pulmonary angiography then showed thrombi in all branches of the pulmonary artery. After heparin therapy symptoms improved and the patient left the hospital in 2 weeks, her condition being stabilized with warfarin and dipyridamole (Persantin). The diagnosis was confirmed by histological examination. Early recanalization of a mesenteric vein was noted. Other reported cases have shown an average prodromal phase of 4 or 5 days. The long-term diarrhea was considered as not connected with the present illness but the presumed influenza illness 2 weeks earlier may have been due to a pulmonary embolism. Of reported cases, 5 of 13 have died. Early diagnosis, prompt surgery, and heparin therpay are considered important.

An unexplained increase in the frequency of pyogenic liver abscesses of unknown etiology has, fourtunately, been paralleled by significant advances in diagnostic and therapeutic methods. This report reviews experience with 14 patients operated upon at NYU Medical Center since 1971. Eight cases (57%) were cryptogenic. Other abscesses were associated with biliary disease (3); abdominal sepsis (2); and trauma (1). Abscesses were present on hospitalization in 12 patients. Clinical findings included fever (101-108 F); 100%; leucocytosis, 71%; anorexia and vomiting, 50%; localized tenderness and hepatomegaly, 50%; hypoalbuminemia, 86%; hypocholesterolemia, 78%; elevated SGOT, 71%; and elevated aikaline phosphatase, 43%. Technetium hepatic scintiscans showed focal defects in 10 of 12 patients (83%), but did not detect multiple abscesses in 2 of these. Hepatic arteriography performed in 10 patients was highly accurate, outlining single abscesses in 6 and multiple abscesses in 4. Furthermore, in one patient a false positive scintiscan was demonstrated by negative arteriography, confirmed by autopsy. In 4 patients, arteriography indicated an abscess in the posterior-superior area of the right hepatic lobe. With precise anatomical localization, a trans-thoracic approach permitted uncomplicated drainage in each case. This approach provides excellent exposure and direct drainage for abscesses in this area. An additional therapeutic adjunct in two patients, with 4 and 11 abscesses each, was postoperative intraportal infusion of antibiotics through the umbilical vein. Thirteen patients (83%) recovered, one dying from pulmonary embolism. Primary hepatic abscesses occur with increasing frequency. Primary hepatic abscesses occur with increasing frequency. Primary hepatic abscesses occur with increasing frequency. The methods described allow more precise preoperative diagnosis and direct surgical drainage.

In a world-wide survey of the results of 5539 highly selective vagotomies (HSVs) performed electively for duodenal ulcer the operative mortality was found to be 0-3%. This was lower than that found in collected series after either vagotomy with drainage (0-8%) or gastric resection with or without vagotomy (over 1%). Necrosis of the lesser curvature occurred in 10 patients (0-2%) after HSV and caused death in 5(0-1%). Such necrosis is probably ischaemic in origin. Hence reperitonealisation of the raw area on the lesser curvature and prompt laparotomy if the patient develops signs of peritonitis might lower the mortality still further. Three deaths were due to pulmonary embolism, one to mesenteric vascular occlusion, and four to myocardial infarction; such deaths might be reduced by the prophylactic use of low-dose heparin. Persisting gastric stasis requiring drainage occurred in only 0-1% of the patients in the early postoperative period and in 0-6% of the patients later. Hence drainage procedures, which produce side effects such as early dumping, bilious vomiting, and diiarrhoea, could be abandoned if the mean incidence of recurrent ulceration after HSV remains close to its present level. HSV is probably the safest operation for duodenal ulcer because the alimentary tract is not opened and there is no anastomosis, suture line, or stoma.

In 1983, a previously healthy 21-year old mother came to University Hospital in Dijon, France feeling weak and had a severe frontal headache with vomiting. Clinical and biochemical tests were normal. She smoked 20 cigarettes/day and used a high dosed combined oral contraceptive (OC) (ethinyl estradiol and cyproterone acetate). 15 days later, the headache returned and she could not understand spoken words and the bilateral section of the brain had slowed. Yet her mental status was normal as were cerebrospinal fluid and cerebral computerized tomography tests. The antiherpes virus drug, vidabarine, did not alleviate symptoms. At least 1 month later, a severe left pulmonary embolism caused acute right heart failure. She also had a prethrombotic left iliac vein, so physicians began heparin therapy, adding nifedipine and buflomedil to control the spasms in the right internal iliac artery and both external iliac arteries. Acute ischemia of the lower limbs eased within a week but sensory disorders remained for 2 months. Satisfactory collaterality transpired due to a blocked left external iliac artery and left iliac vein. The following signs and symptoms indicated her condition to be homocystinuria: blond hair with deep blue eyes, macrocytic anemia, factor VII deficit (51%), strong positive Brandt's reaction, cystine homocystine in the plasma, and presence of homocystine, cystathionine, and methionine in the urine. Physicians took her off the OC and discharged her on vitamin B6/day, folic acid/day, betaine citrate/day, and the anticoagulant Coumadin. A subsequent check of her 19-year old sister found she had it too. They assessed the patient's condition yearly. In 1988, her left leg developed edema and she limped when not using elastic stockings. Effects of iliac vein phlebitis were evident. She no longer suffered from headaches. Since plasma methionine was within the normal range and homocystine no longer was present in plasma and urine, the physicians halted the anticoagulant therapy. In conclusion, the OC precipitated this partial form of homocystinuria.

Chronic intravenous toxicity studies in monkeys were carried out with 3-[(2,3-cyclopenteno-1-pyridinium)-methyl]-7-[2-syn-methoximino - 2-(2-aminothiazol-4-yl)-acetamido]-ceph-3-em-4-carboxylate (cefpirome, HR 810; CAS 84957-29-9) a new cephalosporin derivative. In a 90-day study in rhesus monkeys (4 males/4 females per group) dosages of 0, 50, 160 and 500 mg/kg/day were administered. In a 6-month study 5 groups of 6 male and 6 female cynomolgus monkeys received NaCl-solution (0.9%), the vehicle, and 50, 200 or 800/400 mg/kg/d (the highest dosage had to be lowered after the first week due to acute drug intolerance). For clarification of the dose relationship to the findings in the 800/400 mg/kg group, a supplementary 6-month study with 500 mg/kg cefpirome including a vehicle control was also performed. 50 mg cefpirome/kg/d was well tolerated; so too were 160 and 200 mg/kg apart from a slight beta 2-microglobulinuria and/or enzymuria. Almost exclusively at the high dosages retching and vomiting, and exclusively at the high dosages diarrhea, inappetence and physical weakness were sporadically seen in the first phase of the studies. 500 and 400 mg/kg led to increasing signs of discrete renal tubular changes (enzymuria, beta 2-microglobulinuria, cylindruria and minimal histological changes in 2 animals of the 400 mg/kg group). In one rhesus monkey (500 mg/kg) and two cynomolgus monkeys (800 mg/kg) severe kidney damage had developed within the first week. In all dosage groups of the 90-day study special histological methods revealed a dose-dependent increase and enlargement of lysosomes in the epithelia of the proximal renal tubules. Increased cytolysis was, however, not observed. In all the studies there was a dose-dependent increase in the kidney weights of the intermediate and highest dosage groups. The females of the 400 mg/kg group showed slight anemia accompanied by a slight increase in the reticulocyte count. One animal of this group died prematurely probably due to pulmonary embolism. The signs of slight renal impairment including lysosome enlargement, and the slight anemia proved to be reversible.

(PGF2alpha) Prostaglandin F2alpha was administered intraamniotically to 16 patients in 3 groups: molar pregnancy (8 cases), fetal death (6 cases), and anencephalic fetus (2 cases). These particular types of situations were selected because the effects of PGs upon the product were unknown. PG was administered in dosages between 3 and 200 mcg after being prepared in an ethanol solution. It appeared to have no effect on uterine contractility. It is best to start contractility stimulation with low doses which should be increased progressively according to uterine response. Tone, intensity, frequency, and uterine activity increased when PG dose was increased. Uterine labor as to maturity and cervical dilatation, was studied in the 3 groups. Blood pressure was registered in 2 patients with molar pregnancy; there were no changes during the 1st hours of the study. However, during the last part, differential pressure increased by systolic increase. In 4 patients with fetal death, cervical dilatation register was taken. Average dilatation time (going from 2-10 cm) was 9.50 hours. There were such side effects as slight nausea, vomiting, and chills. 1 of the patients presented with hypotension upon administration of PGF2alpha 200 mcg. 4 patients suffered complications; 1 with molar pregnancy had a possible pulmonary embolism by trophoblast, another had hemorrhage and hypotension, 1 patient with fetal death had immediate hypotension after administration of 200 mcg, and the other had deciduo-myometritis which cleared with antibiotics and curettage. No other subjects experienced complications. Intraamniotic PG administration produced few side effects. (author's modified)

In a series of 250 consecutive open-heart operations, three cases of late cardiac tamponade were noted following the operation. This led the authors to review the literature pertaining to this complication. Ninety-nine cases were collected. The frequency of late tamponade associated with cardiac surgery was 0.62% and was fatal in 16.2% of those cases. The delay before the tamponade appeared varied from 3 days to 3 months (mean 14.5 +/- 7.8 days). The initial clinical picture is insidious and vague, and this constitutes the danger of late cardiac tamponade. The clinical signs are of the respiratory (dyspnea, chest pain), gastrointestinal (anorexia, vomiting) and central nervous (mental confusion, even coma) systems. Pallor with a drop in hematocrit in patients on anticoagulant therapy suggests occult bleeding. A definitive diagnosis depends on catheterization of the right side and on mono- and bidimensional echocardiography. The authors believe that computerized axial tomography represents an interesting noninvasive and reliable examination technique when it can be used during emergency treatment. Pericardial puncture, which is both a diagnostic and therapeutic technique, was useful in one third of the cases; it produced a false-negative result in 12%. The resulting differential diagnoses are pulmonary embolism, myocardial insufficiency and septic shock. Late cardiac tamponade may be produced by one of two mechanisms: hemopericardium due to overdosage of anticoagulants or an exacerbated form of the post-pericardiotomy syndrome. Emergency treatment is always necessary. Pericardiocentesis is a useful diagnostic aid and provides temporary stabilization preoperatively. A wide surgical approach is always indicated. The mortality in untreated patients is 100%. The frequency of immediate relapse or, occasionally, of delayed relapse is estimated to be 11%; relapse may be lethal.

The charts and anaesthetic records of 97 infants less than two years of age who underwent bone marrow transplantation at the University of Minnesota from 1978-1992 were retrospectively reviewed. These infants underwent 564 general anaesthetics. There were 48 perioperative complications, most (39) involving the airway. There were 20 difficult intubations occurring in 13 patients. The causes of the difficult intubations were anatomical abnormalities (12), mucositis (4), pharyngeal oedema (3) and emesis upon induction of anaesthesia (1). Four intraoperative deaths occurred. The deaths were caused by haemorrhage (2), pulmonary embolism (1) and myocardial ischaemia (1). Four patients died within 72 h of surgery; one from cerebral oedema following an intraoperative cardiac arrest, one from fungal septicaemia, one from haemorrhage and one from multiple organ failure following an intracerebral haematoma. Infants undergoing bone marrow transplantation are at high risk for perioperative morbidity and mortality, particularly from complications involving the airway, bleeding or sepsis.

A case is reported of a duodenal perforation by a Kimray-Greenfield filter hook in a 66-year-old female patient. This device had been inserted four years before, after a pulmonary embolism. The patient presented with epigastric pain, vomiting and extracellular dehydration with renal failure. A plain abdominal film showed the filter to be tilted 15 degrees to the left, with an opening 28 mm wide. Various investigations were carried out, none of which providing a satisfactory diagnosis. Steroid treatment (1 mg.kg-1 x day-1 of prednisone) was started before admission to intensive care. Only at that time gastroduodenoscopy showed on of the filter's hooks jutting through the duodenal wall. This perforation was located in the posterior wall of the third part of the duodenum, and was associated with an ulcer of the mucosa facing this hook. The diagnosis was confirmed by an abdominal CT scan. The hook was cut and the perforation sealed off during a first laparotomy. Twenty-six days later, the patient developed intestinal obstruction due to a haematoma of the jejunal wall. She later had a cerebrovascular accident, with status epilepticus and deep coma. She died four months after her admission. The late complications of vena caval filters are discussed. The position of these devices should be regularly checked by a plain abdominal film. Abdominal CT scanning is a useful investigation for the diagnosis of intra and extravascular complications.

Acute pseudo-obstruction of the colon (Ogilvie syndrome) results in massive colonic dilatation that may lead to a life-threatening perforation. This complication is known to occur after arthroplasty of the hip, yet the prevalence of the complication and its effects on the outcome of the procedure are unknown. We reviewed the records of thirty patients (mean age, 74.3 years; range, fifty-six to ninety years) in whom acute colonic pseudo-obstruction developed after hip arthroplasty between 1984 and 1993. During this ten-year period, 10,468 hip arthroplasties were performed at our institution; therefore, the prevalence of acute colonic pseudo-obstruction was 0.29 per cent. The most common presenting symptom was abdominal distention, which occurred a mean of 3.5 days (range, one to eleven days) postoperatively and was noted in twenty-seven of thirty patients. Nausea (fourteen patients), vomiting (eight patients), and abdominal pain (two patients) were observed less frequently. Twenty-one associated medical complications, including pulmonary embolism (four patients), upper gastrointestinal bleeding (three patients), and deep infection (not evident intraoperatively) at the site of the arthroplasty (two patients), developed in fifteen patients. Eighteen of the twenty-one complications occurred after the onset of colonic pseudo-obstruction. The associated medical problems resulted in four deaths (13 per cent). Recognition by the orthopaedic surgeon of the presenting features of acute colonic pseudo-obstruction is important in order to facilitate prompt initiation of treatment, which may hasten recovery and reduce the morbidity and the mortality associated with this complication.
