Peripheral Autonomic Neuropathies
Published in David Robertson, Italo Biaggioni, Disorders of the Autonomic Nervous System, 2019
Sudeck (1900) described a post-traumatic dystrophy in which after minor traumas, usually in the region of the wrist or ankle joint, atrophy and patchy decalcification of bone occurs. Pain may be severe and abnormal vasomotor and sudomotor activity is seen. Many changes in Sudeck atrophy are due to disuse because of pain. This condition can also be successfully treated by sympathectomy.
Management of scleroderma
Published in Aparna Palit, Arun C. Inamadar, Systemic Sclerosis, 2019
Phosphodiesterase-5 (PDE-5) inhibitors (sildenafil, tadalafil, vardenafil) are recommended in patients who do not satisfactorily respond to calcium channel blockers. In patients with severe attacks or critical digital ischemia, intravenous infusion of vasodilator prostaglandins, like iloprost, is advocated. This can be given during the winter months when frequent episodes RP are expected.10 Sympathectomy may also be considered in severe and refractory cases.11,12

In reconstructive microsurgery, sympathectomy is obtained by cutting the nerve endings after flap elevation and pedicle separation. However, catecholamine discharge from the nerve endings can continue until the second postoperative day, and the hyperadrenergic environment increases the susceptibility to vasospasm [38,39]. This situation is prevented by adventitiectomy. Adventitiectomy for perivascular sympathetic denervation is effective in arterial grafts and recipient vessels, but increasing tissue handling and trauma is its most significant disadvantage [5,40,41]. According to our study results, due to acute and long-term vasodilation, perioperative use of topical 2.5% ethanol administration may be an alternative agent for preventing postoperative vasospasm in artery grafts and recipient vessels.

Although there are many treatment options available to treat axillary hyperhidrosis, in our experience, these modalities do not have the same degree of patient satisfaction as the microwave device. Temporary treatments, such as topical aluminum, topical glycopyrrolate, oral anticholinergics, topical anticholinergics, or botulinum toxin, either require frequent application or are associated with a significant financial or time cost (11,12). Permanent treatments include radical surgical excision, liposuction, and endoscopic thoracic sympathectomy(13). These procedures are usually effective, but may be associated with long recovery times, scarring, and retraction. Sympathectomy in particular is associated with compensatory hyperhidrosis, which has been reported to occur in as many as 94% of patients. New and promising treatments for axillary hyperhidrosis include the neodymium-doped yttrium aluminum garnet laser (transcutaneous and subdermal), fractionated microneedle radiofrequency treatment, and high-intensity micro-focused ultrasound (14–17).

Resistant hypertension (RH) is a chronic disease characterized by uncontrollable levels of 140/90 mmHg with the use of four or more blood pressure (BP)-lowering drugs [1]. This chronic disease can cause a higher risk of cardiovascular events, such as myocardial infarction, coronary heart disease, heart failure, and ischemic stroke, as well as chronic kidney disease and death [2]. Therefore, it has received significant attention in the field of global public health. Hypertension can be caused by many factors, including adverse diet and living habits, excessive activation of the renal sympathetic nerve, and hyperactivation of the renin–aldosterone–angiotensin system [3]. Studies have shown that removing sympathetic nerves may reduce BP [4]. However, surgical sympathectomy has been abandoned because of its side effects, trauma, slow recovery, and high morbidity [5].
