One-staged coverage and revascularisation of traumatised limbs by a flow-through radial mid-forearm free flap.

The concept of flow-through circulation in free flaps is an interesting and useful one. Its importance is paramount in the clinical field, if one applies it as a one-staged technique for cover and revascularisation in major trauma of the extremities. This paper describes the practical use of this concept in two clinical cases (hand and foot), in which an uninterrupted arterial and venous flow was established through the radial mid-forearm fasciocutaneous flap, allowing revascularisation of the ischaemic extremity.

[Indirect articular lymphography using Tc 99m-labeled Dextran in animals].

Looking for a standardization of the articular lymphoscintigraphy, an experimental research was conducted on 14 dogs injected in the ankle, with 2.5 mCi of 99m Tc-labeled dextran (P.M. = 70,000). Good scintigraphic images of the lymphatic system have been obtained. After having collected blood samples during the experimentation as well as aliquots of organs and of tissues, after the necropsy of the animal, it was verified that the 99m Tc-labeled dextran was useful for quantitative studies of the articular lymphatic drainage. The activities attained, in the drainage lymph nodes of injected articulation, are 152 times superior to those obtained in the kidney and one gramma of popliteal ganglion was 8929 times more active than one gramma of blood. The dextran 70,000, widely used in our clinical routine, can be injected to the human being, without any risk, and it may be the tracer which permits studies of the articular lymphatic drainage and the usage of the lymphoscintigraphy, already in expansion in many other Medicine branches, in the articular studies, nowadays.

Combined approach to the differential diagnosis of cholestatic jaundice with endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, ultrasonography, and liver biopsy.

A prospective study of 33 patients with cholestatic jaundice was performed with combined use of endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), ultrasonography, and liver biopsy. A higher rate of success with PTC in 25 cases of extrahepatic cholestasis was offset by the better score of ERCP in 8 cases of intrahepatic cholestasis and its wider diagnostic scope. The procedures were complementary in 10 cases. Ultrasonic imaging of intrahepatic bile ducts proved useful for selecting the first cholangiographic technique. Liver biopsy established etiology in intrahepatic cholestasis. Our combined approach allowed us to develop through objective criteria a diagnostic flow chart of cholestasis.

Endoscopy in the upper G.I. bleedings.

From 388 patients with upper G.I. bleeding investigated by endoscopy, radiology or emergent surgery, one third bled from duodenal ulcer, one third oesophageal varices, and from the remain the most frequent were gastric ulcer (14%) and gastric cancer (9%). From a sample of 53 patients with liver cirrhosis, 66% bled from varices and 34% from other lesions. The proportion of patients who bled from oesophageal varices is higher under 60 yrs. The mortality was higher after 60 yrs, except when there was associated chronic liver disease or renal or cardio-respiratory failure. In this group of patients, near half in our series, the mortality is the same under and above 60 years.
