[S1 guideline on intermittent pneumatic compression (IPC)]. / S1-Leitlinie Intermittierende Pneumatische Kompression (IPK, AIK).

Under the direction of the German Society of Phlebology (Deutsche Gesellschaft für Phlebologie) and in cooperation with other specialist associations, the S1 guideline on intermittent pneumatic compression (IPC) was adopted in January 2018. It replaces the previous guideline from March 2005. The aim of the guideline is to optimize the indication and therapeutic use of IPC in vascular diseases and edema. An extensive literature search of MEDLINE, existing guidelines, and work relevant to the topic was performed. In view of the often methodologically weak study quality with often small numbers of cases and heterogeneous treatment protocols, recommendations can often only be derived from the available data using good clinical practice/expert consensus. Intermittent pneumatic compression is used for thromboembolism prophylaxis, decongestive therapy for edema, and to positively influence arterial and venous circulation to improve clinical symptoms and accelerate ulcer healing in both the outpatient and inpatient care setting. The therapy regimens and devices used depend on the indication and target location. They can be used as outpatient and inpatient devices as well as at home for long-term indications. A target indication is thrombosis prophylaxis. IPC should be used in severe chronic venous insufficiency (stages C4b to C6), in extremity lymphedema as an add-on therapy and in peripheral arterial occlusive disease (PAOD) with stable intermittent claudication or critical ischemia. IPC can be used in post-traumatic edema, therapy-resistant venous edema, lipedema and hemiplegia with sensory deficits and edema. Absolute and relative contraindications to IPC must be taken into account and risks considered and avoided as far as possible. Adverse events are extremely rare if IPC is used correctly. If the indication and application are correct-also as an add-on therapy-it is a safe and effective treatment method, especially for the treatment of the described vascular diseases and edema as well as thrombosis prophylaxis.

Residual stumps associated with inguinal varicose vein recurrences: a multicenter study.

PURPOSE: It is unclear whether a residual sapheno-femoral stump left in place after stripping of the great saphenous vein can contribute to the formation of late inguinal varicose vein recurrence. In order to obtain information about the time course of recurrence development, patients with histologically proven residual stumps were recruited and asked about the interval between the initial operation and the first clinical signs of varicose vein recurrence. METHODS: A multi-centre study involving 7 centres was conducted amongst patients undergoing redo-surgery for inguinal varicose vein recurrences. The sapheno-femoral stumps resected during the redo-surgery were classified histologically. Patients with a proven long residual sapheno-femoral stump were asked to describe the first signs of varicose vein recurrence with the help of a standardised questionnaire. From these data the symptom-free interval, consisting of the time frame between the initial operation and the first signs of recurrence, was determined. RESULTS: In 279 legs of 251 patients a long residual sapheno-femoral stump was present. Most patients had experienced a symptom-free interval after the initial operation with a mean duration of 7.4 S.D. 5.5 years. Recurrent varicose veins became apparent after a mean time interval of 6.3 S.D. 5.3 years and congestion symptoms occurred after a mean interval of 8.5 S.D. 5.7 years. CONCLUSIONS: In patients with symptomatic groin recurrences, a long residual sapheno-femoral stump was found in about two thirds of cases. The first clinical signs of varicose vein recurrence can be expected 7-8 years after the initial treatment at the earliest. Long term follow up is required reliably to asses the outcome of treatment for varicose veins.
