The findings suggested that SIADH was the second stage of the triphasic
condition encountered after cranial surgery.
There is also no evidence comparing monophasic to triphasic
Prior to the procedure, all patients were subjected to the following investigations: liver profile (bilirubin, aspartate transaminase, alanine transaminase, alkaline phosphatase, albumin, and INR), complete blood count, alpha-fetoprotein (AFP), conventional abdominal ultrasound (US), and triphasic
CT of the abdomen.
So-called intramolar choriocarcinoma may be encountered in a curettage specimen, (17) where villi of complete mole are surrounded by markedly atypical trophoblastic cells with focal biphasic to triphasic
growth patterns, simulating choriocarcinoma.
Additionally, hemangiomas demonstrate a characteristic triphasic
growth pattern, with initial rapid enlargement (Phase 1 or Proliferating Phase), followed by stabilization and regression (Phase 2 or Involuting Phase), ending with complete involution (Phase 3 or Involuted Phase).
Later models would expand to encompass psychological components of motivation, such as Lief's (1977) model of sexual response that included sexual desire, and Kaplan's Triphasic
Model (Kaplan 1977), which helped inform the categorization and diagnostic criteria of female sexual dysfunction for decades, beginning in 1980 with the publication of the DSM-III (American Psychiatric Association, 1980).
The abdomen was further evaluated with a triphasic
renal CT scan, confirming the presence of a 7 x 25 mm central filling defect within the proximal right ureter (Figures 1-2).
Video EEG showed periodic waves forming in a triphasic
pattern, which occurred every 3-15 seconds, with a frequency of 1 Hz, and are typical for CJD (Figure 2).
Doppler sonography showed a distinct stricture and triphasic
flow loss on the left femoral artery.
Radial and ulnar arterial flows were found to be triphasic
in the Doppler ultrasonography.
Tc-99m labeled triphasic
whole body bone scintigraphy showed a marked focal activity in the right femoral head and in the medial condyle of the right distal femur on the delayed bone phase images (Figure 5).
A duplex ultrasound demonstrated normal triphasic
waveforms extending from the right superficial femoral artery caudally to the proximal popliteal artery.
