Background Topical photodynamic therapy with methyl aminolevulinate (MAL-PDT) is a non-surgical treatment for actinic keratoses, Bowen's disease and basal cell carcinoma. MAL-PDT is particularly useful in elderly patients, who often present co-morbidities and/or in whom surgical excision could be contraindicated. MAL-PDT is generally well tolerated; the most frequent acute adverse events include pain and burning sensation localized to the treatment area. We describe our observation of the occurrence of acute postoperative hypertension (APH) and hypertensive crisis, after a MAL-PDT. Methods BP measurement was taken twice at 2-min intervals, both before and shortly after the MAL-PDT session. APH was defined as an increase in systolic BP by more than 20% or an increase in diastolic BP to above 110mmHg. Hypertensive crisis was defined as a systolic BP 180mmHg or a diastolic BP 110mmHg, with or without acute target organ involvement. Results Prevalence of post-MAL-PDT APH was 22%; 11% of patients developed hypertensive crisis after MAL-PDT, requiring immediate treatment. Conclusion We highlight the importance of blood pressure measurement both before and after MAL-PDT session to identify high-risk patients and to prevent potentially severe organ involvement subsequent to hypertensive crisis.

Abstract

Background Topical photodynamic therapy with methyl aminolevulinate (MAL-PDT) is a non-surgical treatment for actinic keratoses, Bowen's disease and basal cell carcinoma. MAL-PDT is particularly useful in elderly patients, who often present co-morbidities and/or in whom surgical excision could be contraindicated. MAL-PDT is generally well tolerated; the most frequent acute adverse events include pain and burning sensation localized to the treatment area. We describe our observation of the occurrence of acute postoperative hypertension (APH) and hypertensive crisis, after a MAL-PDT. Methods BP measurement was taken twice at 2-min intervals, both before and shortly after the MAL-PDT session. APH was defined as an increase in systolic BP by more than 20% or an increase in diastolic BP to above 110mmHg. Hypertensive crisis was defined as a systolic BP 180mmHg or a diastolic BP 110mmHg, with or without acute target organ involvement. Results Prevalence of post-MAL-PDT APH was 22%; 11% of patients developed hypertensive crisis after MAL-PDT, requiring immediate treatment. Conclusion We highlight the importance of blood pressure measurement both before and after MAL-PDT session to identify high-risk patients and to prevent potentially severe organ involvement subsequent to hypertensive crisis.
