Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
occurrence of short term complications
Tidsramme: the short term complications will be inspected up to 3 months post-op;
|
impaired arterial or venous flap perfusion by increased (>3 seconds) or reduced (<2 seconds) capillary refill time; infection of the reconstructed breast with evidences from microbiological cultures; partial or entire flap necrosis with evident demarcation by clinical observation
|
the short term complications will be inspected up to 3 months post-op;
|
|
occurrence and change of long term complications
Tidsramme: the long term complications will be assessed at 6 months post-op; repeated assessments will be made at 12 and 24 months to record changes
|
fat necrosis proven by breast ultrasound/ breast MRI/ pathology; flap contracture that causes change in shape and/or volume in the reconstructed breast mound observed by naked-eye inspection or breast imaging; capsular contracture that causes hardness/pains or changes of the reconstructed breast mound observed by surgeon's inspection or breast imaging.
|
the long term complications will be assessed at 6 months post-op; repeated assessments will be made at 12 and 24 months to record changes
|
|
occurrence of secondary surgery
Tidsramme: up to 24 months post-op
|
unplanned surgery due to short-term and/or long-term complications post-op, the types of secondary surgery include but not limited to exploratory surgery, flap salvages, removal or fat necrosis, debridement, prosthetic explantation.
|
up to 24 months post-op

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
occurrence of revision surgery
Tidsramme: 6 to 24 months post-op
|
any surgery performed to the reconstructed or contralateral breast to optimize symmetry
|
6 to 24 months post-op
|
|
baseline and change of subjective evaluation
Tidsramme: the baseline evaluation will be made at 6 months post-op; repeated evaluations will be made at 12 and 24 months to record changes
|
patient oriented aesthetic, psychological and overall outcome evaluations are made with BREAST-Q (short for breast-questionnaire) post reconstruction module, the the selected questionnaire includes a set of questions regarding : category 1-patients' satisfaction with breasts; category 2-patients' satisfaction with outcome and category 3-patients' psychological well-being.
In each category, the total score is generated by Q-score (short for questionnaire-score)software and the total score ranges from 0-100.
The higher the score the better the satisfaction.
|
the baseline evaluation will be made at 6 months post-op; repeated evaluations will be made at 12 and 24 months to record changes
