A German medical journal recently opened the topic anew, and declared that (in depth bio here>) Fr. Augustine Lehmkuhl, S.J. advocates the practice of craniotomy in certain cases. The article was reported in the (the original article here>) Medical Record of New York, and (awesome piece here >) Fr. Aloysio Sabetti , S.J. took occasion to answer, or rather to correct the grossly erroneous assumption that Catholic theologians, much less the Church, were tolerant of the practice of craniotomy.
