[Value of color duplex ultrasound in diagnosis of insufficiency of perforant veins. A prospective study of 94 patients].

Using colour coded duplex sonography in pre-operative diagnosis of insufficient perforant veins we succeeded in accomplishing a close correspondence between diagnostic methods and intraoperative findings. We examined 94 patients suffering from primary varicosis by duplex sonography and found 334 perforant veins in total, i.e.

[Diabetic microangiopathy].

On the whole, diabetic microangiopathy can be understood as the clinical renal-retinal syndrome. About 10% of all diabetics die of end-stage renal failure, more frequent in IDDM. With an incidence of 14% diabetic retinopathy is one of the major causes of blindness in adulthood.

[Incidence and symptomatology of lung embolism in relation to the site of deep venous thrombosis].

The uncertainty about the true incidence of pulmonary embolism (PE) in connection with deep venous thrombosis (DVT) becomes evident when comparing the results of autopsy--vs. clinical studies, with the former showing a three-fold elevated rate of embolisation. In order to evaluate the percentage of clinically inapparent PE, all patients (65 females, 54 males, mean age 61.

[Risk profile and macroangiopathy in type II diabetics in medical practice].

The risk profile and the macro-vascular complications of patients with type II diabetes mellitus (NIDDM) was investigated in general practice patients for the first time in the FRG. It was the aim of the study to evaluate the efficacy of the therapy and possible improvements after detailed instructions in a random sample of well defined NIDDM in the greater Munich area. 290 NIDDM (187 female, 103 male) out of a total of 1500 patients treated by 22 general practitioners were randomly recruited for the study.
