Abstract
Poorly controlled hypertension was incidentally cured after performing an endoscopic sympathetic block (ESB) in a patient with hyperhidrosis craniofacialis (HHC). A survey of the literature indicated that 30% to 40% of essential hypertension is of sympathetic origin. Patients with facial sweating associated with hypertension were then studied to determine whether blood pressure is lowered after performing ESB. Between November 2002 and July 2003, 17 hypertensive patients (13 males and 4 females) ranging in age from 22 to 62 years underwent ESB solely for HHC at the Department of Surgery of Kaohsiung Medical University, Taiwan. Their preoperative systolic blood pressure (SBP) values ranged from 170±6 to 200.7±7.6 mmHg, and their diastolic blood pressure (DBP) values ranged from 94.7±6.1 to 120.3±5.7 mmHg. Their heart rates were between 92.67±2.28 and 119.67±5.13 beats per minute (bpm). They were refractory to aggressive medical treatment, including lifestyle modifications and antihypertensive medications. Their postoperative blood pressure, heart rate and surgical outcomes were recorded. After performing ESB, HHC was cured in all 17 patients. Based on the reductions in blood pressure and heart rate, the patients could be divided into two groups, one showing high-level reductions (Group T) and one showing low-level reductions (Group S). The blood pressure of Group T (ten patients) was reduced to the range of 120.2±6.9 to 131.6±3.5 mmHg SBP and 74.8±3.1 to 85.4±4.5 DBP, and the heart rate of this group was reduced to the range of 65.36±4.63 to 85±3.60 bpm, while the blood pressure and heart rate of Group S (seven other patients) were reduced to the ranges of 145.9±5.7 to 160.5±5.5 mmHg SBP, 90±4 to 100.7±3.2 mmHg DBP, and 80±4 to 90.83±3.53 bpm, respectively. The patients in Group S were well controlled at 119.8±5.5 to 130.6±8.0 mmHg SBP and 70.1±3.8 to 84.5±5.7 mmHg DBP with a daily low-dose of calcium channel blocker. The average follow-up periods of the two groups were 17.00±2.906 and 17.43±2.37 months, respectively. We named this surgically curable form of hypertension “Sympathetic Hypertensive Syndrome” (SHS), which we define by the presence of all three of the following: 1) stage II hypertension; 2) HHC or other sympathetic disorders; and 3) heart rate ≥100 bpm. If the patient is male the reductions of blood pressure after the surgery will be better, which might be due to the link with Y chromosome. Finally, we recommend that ESB should be performed in patients with SHS, although the female would respond less satisfactorily in terms of the blood pressure.
