When confronted with such poor results, our can be used with a distal or proximal ring, with a double group developed an intraluminal ring model for the treat- ring, or with an elephant trunk extension (Figure 22. Afer con- ducting a series of experimental studies, we concluded that the intraluminal prosthesis mounted with an intraluminal ring  was eﬃcient and safe, without observing any of the previously described complications. Nearly 20 years ago, we began to use the intraluminal ring for the treatment of acute ascending dissections of the aorta, and obtained favo- (b) rable results with a marked reduction in mortality. Based on our encouraging early experience using the intraluminal ring, we gained enough conﬁdence to begin using this tech- nique in all segments of the aorta, especially in cases where conventional anastomosis was diﬃcult and presented a serious risk of bleeding. We have used intraluminal ring grafs to repair the ascending aorta and/or aortic arch in approximately 500 patients with respectable results. Repeating prosthesis into an intraluminal prosthesis of any length the process at the opposite end of the graft creates a double-ring prosthesis. The ring anastomosis of the intraluminal prosthesis can be placed proximal or distal to the left subclavian artery, rechanneling the aortic flow and occluding the entrance of the false lumen. Choosing the best access is onto the body of the ring and then tied to its groove (note that the diameter diﬃcult because diseases of this segment ofen extend to of the ring should be 4 mm smaller than the prosthesis). Although perfusion and cerebral protection techniques have developed, these extensive repairs of the aorta involve multiple sutures that are diﬃcult to Overall experience access, leading to bleeding, prolonged time of cerebral ischemia, and serious complications. In our experience, the intraluminal ring has been used [6,7] described the use of the intraluminal ring graf for in all segments of the aorta and in many clinical setings, treatment of diseases of the ascending aorta and the aor- including dissection and aneurysm rupture [5,6]. In 785 patients, we employed the that the technique transforms very complicated aortic intraluminal ring as the anastomotic technique. We used a reconstructions into simpler and faster procedures with total of 1098 rings. For example, we have used the intraluminal ring, 201 of them had acute ascending the intraluminal ring in high-risk patients with compli- aortic dissection (25.

A bifurcated graft was used to restore circulation to the innominate and left common carotid arteries, and the intraluminal ring with an elephant trunk was secured to the aortic wall proximal to the left carotid artery. The aortic root was replaced using the Cabrol technique for coronary reattachment. Prior to the sternotomy, we introduce an arterial cannula into the right axillary and right femoral arter- ies (Figure 22.

We depict individual subjectivity in terms of affective patterns, mental content, accompanying somatic states, and associated relationship patterns. To have an overview of the mental health field, it is essential, in addition to sim- ply listing their symptoms, to consider the subjective lived experience of people with psychiatric disorders. Subjective experiences have been particularly neglected, since 134 Symptom Patterns: The Subjective Experience—S Axis 135 the usual methodologies of “descriptive” or “categorical” psychiatry are not adequate to reflect the complexity of human subjective experience in pathological and non- pathological conditions that may need attention and/or treatment. People in the same diagnostic category, with similar symptoms, may still vary widely in their subjective experience, and these variations have implications for treatment. A deeper exploration would be expected to merge some diagnos- tic categories and differentiate others. This chapter on symptom patterns is placed third in our overall diagnostic profile for adulthood because such patterns are best understood in the context of a patient’s overall personality structure and profile of mental functioning. Symptoms such as anxiety, depression, and/or impulse-control problems may be part of an overall emo- tional challenge. For example, problems with impulse control and mood regulation are common in patients with the larger developmental deficit of inability to represent (symbolize) a wide range of affects and wishes. In some instances, notably those in which there has been long-standing psycho- analytic scholarship, we comment on psychodynamic understandings of a given symp- tom pattern and include general implications for treatment, transference, and counter- transference. Differential Diagnosis of Certain Subjective Experiences Some symptoms, such as fear, anxiety, and sadness, are universal, and consequently also common in most psychiatric disorders and nonpsychopathological conditions. Symptoms may have specific interactions, such as those delusions that derive from hallucinations. These anomalous subjective experiences are most often psychological (“psychogenic,” 136 I. Thus substance-mediated symptoms and symptoms caused by another medical condi- tion should always be considered. These are the most common unpleasant subjective states and may appear in almost any disorder. When they are relatively monosymp- tomatic, pronounced, or specific, an anxiety or depressive disorder can be diagnosed. When their absence seems perplexing, then a search for a “primary gain” or for a specific mental functioning (examples include emotional blunting, isolation of affect, la belle indifférence, dissociation of affect, etc. These may be direct bodily expressions of emotional pain, especially in persons not psychologically minded. Symptoms may include tactile posttraumatic flashbacks of real past events, whose origins are murky because auto- biographical memory and context are missing. They may be somatic “betrayals” of unacceptable repressed impulses, as in classic conversion disorders. Negative somato- form symptoms, such as conversion anesthesia for sharp pain, commonly accompany self-mutilation and worsen its prognosis.
