A case of chylorrhea arising after median sternotomy for treatment of atrial septal defect was reported. The patient was a 55-year-old male, who had visited our outpatient clinic with a complaint of edema in the bilateral lower legs in June 1990. Under a diagnosis of atrial septal defect, a patch closure was performed in November. On the 5th postoperative day, a full liquid diet was started. Two hours and a half after the food intake, the drainage from a tube inserted into the anterior mediastinum turned milky white. Chylorrhea was diagnosed. The patient was placed in N.P.O. and maintained by an intravenous hyperalimentation. Drainage of 250-350ml/day milky white fluid persisted until the 14th postoperative day, when a 5cm removal of the mediastinal tube resulted in dramatic decrease in drainage. Thus chylorrhea in this case was cured by conservative treatment.

A Pulmonary arterial flow-directed catheter (Oxymetry 93A-741-7.5F), combining the fiberoptic reflectometric system of continuous measurement of mixed venous blood oxygen saturation (SvO₂) was used for hemodynamic measurements including thermodilution cardiac output estimation and hemoglobin value in 21 cases of open heart surgery. Immediately after open heart surgery there was low correlation between Hb (hemoglobin value) and SvO₂ (r=0.513, p<0.05). However there was no correlation between SvO₂ and cardiac function (pulmonary capillary wedge pressure and cardiac index). With almost normal Hb (10-13g/dl) the average cardiac index (CI) in cases of SvO₂ less than 60% was 2.47l/min/m² which was significantly lower than those with SvO₂ more than 60% (p<0.01). With normal CI (2.5-4.0l/min/m²) the average Hb in cases of SvO₂ less than 60% was 7.40g/dl which was significantly lower than those of more than 60% (p<0.01). This study suggested that there is low cardiac function or severe anemia in the state of SvO₂ less than 60%.

We studied the effects of granulocytic elastase (GEL) and fibronectin (FN) on the coagulation and fibrinolytic system when using cardiopulmonary bypass (CPB). Blood sampling was performed before CPB (Pre), just after CPB (Post) the 1st postoperative day (PD1) and the second postoperative day (PD2). Laboratory parameters were GEL, FN, fibrinogen (Fib), prothrombin time (PT), fibrin degradation products (FDP), D dimer (D-D), α2 plasmin inhibitor plasmin complex (PIC) and antithrombin III (AT III). The level of GEL was highest and that of FN was lowest at Post. The levels of Fib, PT and AT III were lowest and that of PIC was highest just after CPB. The levels of FDP and D-D were highest on PD1. The levels of GEL and D-D correlated just after CPB and on PD1 and PD2. The level of GEL correlated with that of PIC on PD1. These results demonstrated that the level of FN decreased with CPB. And it was expected that CPB time affected the level of GEL. The levels of GEL affects D-D and PIC which are fibrinolysic factors particularly related to secondary fibrinolysis.

Introduction: Calciphylaxis is a rare disorder characterized by painful ischemic skin ulcers. There is currently no approved therapy and its pain management is often challenging. Case: A 40-year-old female was diagnosed with calciphylaxis seven years after starting hemodialysis. Despite the administration of sodium thiosulfate intravenous and intralesional combination therapy, the ulcers progressed on both lower limbs and buttocks. She suffered from terrible and opioid refractory pain due to ulcers. After careful consideration of the appropriateness, a lumbar sympathetic ganglion block (LSGB) was performed. Six months later, all the ulcers had re-epithelialized and she was relieved of pain. Conclusion: While the appropriateness of LSGB must be carefully evaluated, it could be a treatment option for patients with central-type calciphylaxis.
